Ablon JS and Jones EE
- Abstract
OBJECTIVE: This research extends a series of studies that have examined the process of psychotherapy. The authors hypothesized that manual regimens of psychotherapy compared in a controlled clinical trial would overlap considerably in process and technique and that intervention strategies common to both treatments would be responsible for promoting patient change. METHOD: Expert therapists developed prototypes of the ideal regimens of brief interpersonal psychotherapy and cognitive behavior therapy using the Psychotherapy Process Q-Set, an instrument designed to provide a standard language for describing treatment processes. A separate set of clinical judges then used the Psychotherapy Process Q-Set to score the actual transcripts of interpersonal psychotherapy and cognitive behavior therapy sessions conducted as part of the NIMH Treatment of Depression Collaborative Research Program. The expert prototypes were then compared with actual therapy administered in order to determine the extent to which each form of therapy conformed to its ideal prototype. RESULTS: Both the interpersonal psychotherapy and cognitive behavior therapy sessions adhered most strongly to the ideal prototype of cognitive behavior therapy. In addition, adherence to the cognitive behavior therapy prototype yielded more positive correlations with outcome measures across both types of treatment. CONCLUSIONS: Relying on brand names of therapy can be misleading. These findings suggest that the basic premise of controlled clinical trials (i.e., that the compared interventions represent separate and distinct treatments) may not have been met in the NIMH Treatment of Depression Collaborative Research Program. The implications of these findings for using controlled clinical trials to study psychotherapy are discussed. [ABSTRACT FROM AUTHOR]

- Abstract
In 192 oocyte donation cycles performed between January 1993 and July 1996, we examined the width of 'the window for embryo transfer' using standard hormonal replacement methods. All transfers were performed within 48 h of insemination. We varied the day of embryo transfer with regard to the initiation of progesterone therapy and, thus, the duration of endometrial exposure to progesterone and analysed the resulting pregnancy rates. Patients were divided into five groups (I-V) and embryo transfers were performed 2, 3, 4, 5 or 6 days following initiation of progesterone therapy. The number of pregnancies per transfer cycle achieved in groups I-V were 0 (0%), 3 (12%), 16 (40%), 29 (48.3%), and 10 (20.4%) respectively. The increased pregnancy rate in group III in comparison to group II is statistically significant (P < 0.03). Furthermore, the pregnancy rate in group IV (5 days of progesterone administration before embryo transfer) was significantly higher than in group V (6 days of progesterone administration before embryo transfer; P < 0.005). We also noted that, when embryos were transferred 4 or 5 days after initiation of progesterone therapy, the pregnancy rates were not significantly different between menopausal and cycling recipients (50% vs 43.7%). Our results indicate that the window for embryo transfer is dependent on duration of treatment with progesterone; it begins approximately 48 h after starting progesterone administration and lasts for approximately 4 days. The optimum period for transferring embryos at the 4- to 8-cell stage corresponds to cycle days 18 and 19. Transfers performed on the 17th and 20th days of the cycle can result in successful implantation, although the rates of implantation are highest when transfers are done on days 18 and 19.

Five diets were tested for their capacity to promote weight gains in newly-weaned, 19-d-old, rotavirus-exposed pigs. The diets were tested under conditions designed to minimize the stress of weaning. That is, rotavirus-exposed pigs were moved at weaning to an isolation unit, caged individually and fed hourly liquid diets that were high (approximately 26%) and low in protein (approximately 11%). In all experiments, pigs experienced postweaning rotavirus-associated diarrhea and depression in rate of gain. Pigs grew faster: when fed diets high in protein (approximately 26% protein) vs low in protein (approximately 11% protein) and when fed diets containing cows' milk proteins vs proteins from soybean flour. A diet containing antibodies to rotavirus did not ameliorate the weanling diarrhea.

A method has been developed in rabbits by which hormones can be injected directly into the follicular antrum without impairing the ability of the follicle to ovulate. When 10 ng of LH or 100 ng of FSH are injected into single follicles they ovulate, as determined by ovulation points and by the demonstration of ova in the oviduct. Saline-treated adjacent follicles do not ovulate. The rate of ovulation is not significantly different from that obtained by the intravenous administration of these hormones. Ovulation occurs 10.5 h after treatment. Prolactin, TSH, or saline were unable to induce ovulation. The contamination of FSH by LH cannot account for the ability of FSH to cause ovulation. Combinations of 75 ng of FSH and 5 ng of LH, doses which do not cause ovulation when the hormones are given separately, are effective in inducing ovulation. It is concluded that the ovulation-inducing hormone is a complex of FSH and LH. When less than ovulatory doses of LH (1-5 ng) or of FSH (10-20 ng) are injected, the treated follicles invariably luteinize in the presence of the ovum. Ovulated or luteinized follicles produce amounts of progesterone comparable to corpora lutea (CL) of pseudopregnant rabbits. In spite of innumerable studies on the role of LH in the process of ovulation, the identity of the ovulation-inducing hormone remains uncertain. Both FSH and LH are known to be released simultaneously and shortly prior to ovulation in such diverse species as man, rats, and sheep. It is now known that the same releasing factor (GNRF) releases both FSH and LH (Schally et al., 1971). These findings further raise the question whether the simultaneous release of the two gonadotropins is incidental or whether they both play a role in the induction of ovulation. That either LH or FSH can

- Abstract
Background Intraoperative safety protocols, including proper labelling of syringes, are critical to patient safety in surgical settings. While the Royal Pharmaceutical Society and the Royal College of Anaesthetists provide clear guidelines to prevent medication errors, ensuring consistent compliance with labelling protocols in the fast-paced and complex environment of orthopaedic surgery can still present practical challenges. The absence of proper labelling, combined with the use of multiple fluids such as normal saline, disinfectants, and local anaesthetics, increases the risk of adverse outcomes due to fluid misidentification. This quality improvement project aimed to assess current labelling practices in a district general hospital, identify barriers to compliance, and develop a cost-effective solution. Methodology The project was conducted in three orthopaedic theatres over two audit cycles. During the first audit cycle, 30 procedures were observed to assess compliance with labelling guidelines. Compliance was defined as the labelling of all syringes containing fluids present in the sterile field. Following this, an intervention was introduced, using surgical marker pens and sterile stickers for fluid labelling, along with a mandatory "tactical pause and check" and an awareness campaign. Two months later, a second audit of 34 procedures was conducted to evaluate the effectiveness of the intervention. Results In the first audit cycle, only three out of 30 procedures (10%) were compliant with labelling guidelines. Following the intervention, compliance increased dramatically to 32 out of 34 procedures (94%). The results were statistically significant (p < 0.05) as determined by Fisher's exact test. The use of sterile stickers and marker pens proved to be a simple and cost-effective solution that did not interfere with the sterile environment or increase costs. Conclusions This study demonstrates that a low-cost intervention using sterile stickers and surgical marker pens can significantly improve compliance with fluid labelling guidelines in orthopaedic surgery, thereby enhancing patient safety. While the intervention was successful, future research should explore more sustainable solutions, such as pre-printed sterile labels, and evaluate the long-term impact of such interventions across various surgical settings. Continuous education and regular audits will be essential in maintaining high compliance rates., Competing Interests: Human subjects: All authors have confirmed that this study did not involve human participants or tissue.

- Abstract
Understanding host-microbe interactions in planta is an expanding area of research. Amplicon sequencing of the 16S rRNA gene is a powerful and common method to study bacterial communities associated with plants. However, the co-amplification of mitochondrial and plastid 16S rRNA genes by universal primers impairs the sensitivity and performance of 16S rRNA sequencing. In 2020, a new method, Cas-16S-seq, was reported in the literature to remove host contamination for profiling the microbiota in rice, a well-studied domestic plant, by engineering RNA-programmable Cas9 nuclease in 16S rRNA sequencing. For the first time, we tested the efficiency and applicability of the Cas-16S-seq method on foliage, flowers, and seed of a non-domesticated wild plant for which there is limited genomic information, Leptospermum scoparium (mānuka). Our study demonstrated the efficiency of the Cas-16S-seq method for L. scoparium in removing host contamination in V4-16S amplicons. An increase of 46% in bacterial sequences was found using six guide RNAs (gRNAs), three gRNAs targeting the mitochondrial sequence, and three gRNAs targeting the chloroplast sequence of L. scoparium in the same reaction. An increase of 72% in bacterial sequences was obtained by targeting the mitochondrial and chloroplast sequences of L. scoparium in the same sample at two different steps of the library preparation (DNA and 1st step PCR). The number of OTUs (operational taxonomic units) retrieved from soil samples was consistent when using the different methods (Cas-16S-seq and 16S-seq) indicating that the Cas-16S-seq implemented for L. scoparium did not introduce bias to microbiota profiling. Our findings provide a valuable tool for future studies investigating the bacterial microbiota of L. scoparium in addition to evaluating an important tool in the plant microbiota research on other non-domesticated wild species., (© 2024.

- Abstract
Aims: Arbuscular mycorrhizal fungi (AMF) can perform significant functions within sustainable agricultural ecosystems, including vineyards. Increased AMF diversity can be beneficial in promoting plant growth and increasing resilience to environmental changes. To effectively utilize AMF communities and their benefits in vineyard ecosystems, a better understanding of how management systems influence AMF community composition is needed. Moreover, it is unknown whether AMF communities in organically managed vineyards are distinct from those in conventionally managed vineyards., Methods and Results: In this study, vineyards were surveyed across the Marlborough region, New Zealand to identify the AMF communities colonizing the roots of different rootstocks grafted with Sauvignon Blanc and Pinot Noir in both conventional and organic systems. The AMF communities were identified based on spores isolated from trap cultures established with the collected grapevine roots, and by next-generation sequencing technologies (Illumina MiSeq). The identified AMF species/genera belonged to Glomeraceae, Entrophosporaceae, and Diversisporaceae. The results revealed a significant difference in AMF community composition between rootstocks and in their interaction with management systems., Conclusions: These outcomes indicated that vineyard management systems influence AMF recruitment by rootstocks and some rootstocks may therefore be more suited to organic systems due to the AMF communities they support. This could provide an increased benefit to organic systems by supporting higher biodiversity., (© The Author(s) 2024.

- Abstract
Fungal endophytes inhabit a similar ecological niche to that occupied by many phytopathogens, with several pathogens isolated from healthy tissues in their latent phase. This study aimed to evaluate the pathogenicity, the colonisation ability, and the enzyme activity of 37 endophytic fungal isolates recovered from apparently healthy apple shoot and leaf tissues. The pathogenicity of the isolates was assessed on 'Royal Gala' and 'Braeburn' fruit and detached 'Royal Gala' shoots. For the non-pathogenic isolates, their ability to endophytically colonise detached 'Royal Gala' shoots was evaluated. Enzyme activity assays were undertaken to determine whether the pathogenicity of the endophytes was related to the production of the extracellular enzymes, amylase, cellulase, pectinase, protease, and xylanase. Of the 37 isolates studied, eight isolates, representing the genera Colletotrichum, Diaporthe, Fusarium, and Penicillium, were shown to be pathogenic on both apple shoots and fruit. Two isolates identified as Trichoderma atroviride, were pathogenic only on shoots, and three isolates, representing the genus Diaporthe, were pathogenic only on fruit. Of the remaining 24 isolates, 22 (Biscogniauxia (n = 8), Chaetomium (n = 4), Trichoderma (n = 3), Epicoccum (n = 2), Neosetophoma (n = 2), Xylaria (n = 1), Daldinia (n = 1), and Paraphaeosphaeria (n = 1)) were recovered from the inoculated apple shoots but two failed to colonise the shoot tissues. Of the isolates tested, 20 produced amylase, 15 cellulase, 25 pectinase, 26 protease, and 13 xylanase. There was no correlation between the range and type of enzymes produced by the isolates and their pathogenicity or ability to endophytically colonise the shoot tissue. The study showed that approximately one-third (13/37) of the isolates recovered from the apparently healthy apple shoot tissues were observed as latent pathogens. The isolates that did not cause disease symptoms may have the ability to reduce colonisation of apple tissues by pathogens including Neonectria ditissima associated with European canker of apple., Competing Interests: Declaration of competing interest The authors declared that there is no conflict of interest., (Copyright © 2024 The Authors.

- Abstract
Individual differences in reactivity to unpredictable threat (U-threat) have repeatedly been linked to symptoms of anxiety and drinking behavior. An emerging theory is that individuals who are hyper-reactive to U-threat experience chronic anticipatory anxiety, hyperarousal, and are vulnerable to excessive alcohol use via negative reinforcement processes. Notably, anxiety and alcohol use commonly relate to disruptions in sleep behavior and recent findings suggest that sleep quality may impact the link between reactivity to U-threat and psychiatric symptoms and behaviors. The aim of the current study was to examine the unique and interactive effects of reactivity to U-threat and sleep quality on anxiety symptoms and drinking behavior in a cohort of youth, ages 16-19 years. Participants (N = 112) completed a well-validated threat-of-shock task designed to probe individual differences in reactivity to U-threat and predictable threat (P-threat). Startle eyeblink potentiation was recorded during the task as an index of aversive reactivity. Participants also completed well-validated self-report measures of anxiety and depression symptoms, lifetime alcohol use, and current sleep quality. Results revealed significant startle reactivity to U-threat by sleep quality interactions on anxiety symptoms and lifetime drinking behavior. At high levels of sleep disturbance (only), greater reactivity to U-threat was associated with greater anxiety symptoms and total number of lifetime alcoholic beverages. These results suggest that sensitivity to uncertainty and chronic hyperarousal increases anxiety symptoms and alcohol use behavior, particularly in the context of poor sleep quality., (© 2024 Society for Psychophysiological Research.)

14. Childhood Adversity and Youth Suicide Risk: The Mediating Role of Intolerance of Uncertainty.

- Abstract
Exposure to adverse childhood experiences (ACEs) is a well-established risk factor for suicidality in adolescence and young adulthood. However, the specific mechanisms underlying this relationship remain unclear. Existing research and theoretical frameworks suggest alterations in cognitive and affective processes may account for this association. Intolerance of uncertainty (IU) exacerbates negative affect and arousal states and may contribute to sustained distress. It is therefore plausible that ACEs may be associated with high IU, and in turn, high IU may be associated with increased suicide risk. The present study directly tests this hypothesis in a cohort of youth (18-19 years) with varying ACE exposure. Participants with and without a history of trauma (N=107) completed a battery of self-report questionnaires to assess ACEs, IU, and suicide risk. Results revealed ACEs were significantly associated with both IU and suicide risk. IU and suicide risk were also correlated. Importantly, findings demonstrated a significant indirect effect of ACEs on suicide risk through IU. Findings converge with broader literature on the relationship between childhood adversity and suicidality and extend previous research by highlighting IU as a mediator of this relationship, positing IU as a potentially viable target for suicide prevention among those with a history of ACEs., Competing Interests: Declaration of Interests All authors declare no conflicts of interest.

- Abstract
Aims: Sclerotinia sclerotiorum is an important pathogen of a wide range of crops, with current control mostly relying on the use of fungicides. This study assessed the effect of biofumigation on in vitro inhibition of mycelial growth and reduction of sclerotial viability of S. sclerotiorum as an attempt to seek an alternative management strategy., Methods and Results: The effect of different biofumigant crop types to inhibit mycelial growth of ten S. sclerotiorum isolates was investigated, with Brassica juncea 'Caliente 199' being the most effective biofumigant crop. The efficacy of 'Caliente 199' to inhibit mycelial growth and reduce sclerotial viability was influenced by different crop factors. Plant tissue of 'Caliente 199' harvested at 50% or 100% flowering and adjusted to 80% (w/w) moisture resulted in greater mycelial inhibition and a reduction in the sclerotial viability compared with the vegetative tissue with the same plant moisture. Mycelial inhibition and reduction of sclerotial viability were affected by tissue quantity. Whole plant tissue and shoots only resulted in a similar inhibition of mycelial growth, but whole plant tissue resulted in a greater reduction of sclerotial viability. The S. sclerotiorum isolates differed in sensitivity to the volatile bioactive compounds released by the biofumigant plant tissue., Conclusions: The volatile bioactive compounds released by 'Caliente 199' resulted in effective mycelial inhibition but did not kill sclerotia completely., (© The Author(s) 2023.

- Abstract
Background: Antimicrobial resistance and therapy-related adverse effects make Mycobacterium abscessus treatment challenging. Omadacycline is a novel, bioavailable aminomethylcycline with favourable in vitro activity against M. abscessus., Aims: To describe a case report and review the published literature describing outcomes for M. abscessus infections treated with omadacycline., Methods: Systematic literature review., Results: We identified three articles that, in addition to our case report, describe 18 patients. Pulmonary infections were most frequent. Minimum inhibitory concentrations were reported for two isolates (0.25 and 0.5 mg/L). Despite half the patients starting omadacycline because of failure of prior therapy, 15 (83%) had a favourable outcome, defined as 'cure', 'improvement' or 'clinical success' as determined by the primary study authors. One patient (6%) discontinued omadacycline because of gastrointestinal intolerance., Conclusions: Although the limited observational data and in vitro susceptibility results are encouraging, randomised control trials are required to determine the role of omadacycline as part of combination therapy for this most difficult-to-treat pathogen., (© 2023 The Authors.

- Abstract
To assess the correlation of orthopedic surgery residents compared with expert geriatricians in the assessment of frailty stage using the Clinical Frailty Scale (CFS) in patients with hip fractures. A retrospective chart review was performed from January 1, 2015 to December 31, 2019. Patients admitted with a diagnosis of hip fracture were identified. Those patients with a CFS score completed by orthopedic residents with subsequent CFS score completed by a geriatrician during their admission were extracted. Six hundred and forty-eight patients over age 60 (mean 80.5 years, 73.5% female) were admitted during the study period. Orthopaedic residents completed 286 assessments in 44% of admissions. Geriatric medicine consultation was available for 215 patients such that 93 patients were assessed by both teams. Paired CFS data were extracted from the charts and tested for agreement between the 2 groups of raters. CFS assessments by orthopedic residents and geriatrician experts were significantly different at P < .05; orthopedic residents typically assessed patients to be one CFS grade less frail than geriatricians. Despite this, the CFS assessments showed good agreement between residents and geriatricians. Orthopaedic surgery residents are reliable assessors of frailty but tend to underestimate frailty level compared with specialist geriatricians. Given the evidence to support models such as orthogeriatrics to improve outcomes for frail patients, our findings suggest that orthopedic residents may be well positioned to identify patients who could benefit from such early interventions. Our findings also support recent evidence that frailty assessments by orthopedic surgeons may have predictive validity. Low rates of initial frailty assessment by orthopedic residents suggests that further work is required to integrate more global comprehensive care., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2023 the Author(s).

- Abstract
Grapevine trunk diseases (GTDs) are a substantial challenge to viticulture, especially with a lack of available control measures. The lack of approved fungicides necessitates the exploration of alternative controls. One promising approach is the investigation of disease escape plants, which remain healthy under high disease pressure, likely due to their microbiome function. This study explored the microbiome of grapevines with the disease escape phenotype. DNA metabarcoding of the ribosomal internal transcribed spacer 1 (ITS1) and 16S ribosomal RNA gene was applied to trunk tissues of GTD escape and adjacent diseased vines. Our findings showed that the GTD escape vines had a significantly different microbiome compared with diseased vines. The GTD escape vines consistently harbored a higher relative abundance of the bacterial taxa Pseudomonas and Hymenobacter . Among fungi, Aureobasidium and Rhodotorula were differentially associated with GTD escape vines, while the GTD pathogen, Eutypa , was associated with the diseased vines. This is the first report of the link between the GTD escape phenotype and the grapevine microbiome., Competing Interests: HR, DM, and SB are employed by The New Zealand Institute for Plant and Food Research Limited.

- Abstract
Introduction: This cross-sectional study explores the contributions of personal and contextual factors in the adjustment process of a sample of internationally mobile children and adolescents having relocated to Switzerland. Based on evolutionary developmental theories and recommendations by Research Domain Criteria and The Hierarchical Taxonomy of Psychopathology theoretical frameworks, we hypothesized and tested a heuristic model of TCK adjustment, aiming to identify prevention and treatment targets tailored for our sampled population., Methods: We assessed the relationships in the hypothesized models, particularly how perceived and acculturative stress influence TCK adjustment and whether the relationship between the predictors of TCK stress and the outcomes of TCK adjustment are mediated by resilience and family functioning. A total of 143 participants aged 7-17, having relocated internationally with their working parent(s), recruited in local and international schools in Switzerland, were included in this study. Data were collected using an online survey after we collected consent. We assessed factors of adjustment using validated questionnaires: perceived stress and acculturative stress and the potential mediating roles of family functioning and resilience. We measured the outcome of adjustment through mental health difficulties and sociocultural adjustment. We used path analysis to test the model., Results: Results highlight the contributions of perceived stress and acculturative stress to TCK mental health and sociocultural adjustment. We also we found a mediation effect for resilience in the relationship between perceived stress and mental health. Family functioning was not a significant mediator in any relationship that we assessed., Discussion: We discuss implications for future research, promoting TCK adjustment and preventative psychotherapeutic interventions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Jones, Reed, Meyer, Gaab and Ooi.)

- Abstract
Arbuscular mycorrhizal fungi (AMF) deliver potentially significant services in sustainable agricultural ecosystems, yet we still lack evidence showing how AMF abundance and/or community composition can benefit crops. In this study, we manipulated AMF communities in grapevine rootstock and measured plant growth and physiological responses. Glasshouse experiments were set up to determine the interaction between rootstock variety and different AMF communities, using AMF communities originating under their own (i.e., "home") soil and other rootstocks' (i.e., "away") soil. The results revealed that specific AMF communities had differential effects on grapevine rootstock growth and nutrient uptake. It was demonstrated that a rootstock generally performed better in the presence of its own AMF community. This study also showed that AMF spore diversity and the relative abundance of certain species is an important factor as, when present in equal abundance, competition between species was indicated to occur, resulting in a reduction in the positive growth outcomes. Moreover, there was a significant difference between the communities with some AMF communities increasing plant growth and nutrient uptake compared with others. The outcomes also demonstrated that some AMF communities indirectly influenced the chlorophyll content in grapevine leaves through the increase of specific nutrients such as K, Mn, and Zn. The findings also indicated that some AMF species may deliver particular benefits to grapevine plants. This work has provided an improved understanding of community level AMF-grapevine interaction and delivered an increased knowledge of the ecosystem services they provide which will benefit the wine growers and the viticulture industry., (© 2022.

- Abstract
One Biosecurity is an interdisciplinary approach to policy and research that builds on the interconnections between human, animal, plant, and ecosystem health to effectively prevent and mitigate the impacts of invasive alien species. To support this approach requires that key cross-sectoral research innovations be identified and prioritized. Following an interdisciplinary horizon scan for emerging research that underpins One Biosecurity, four major interlinked advances were identified: implementation of new surveillance technologies adopting state-of-the-art sensors connected to the Internet of Things, deployable handheld molecular and genomic tracing tools, the incorporation of wellbeing and diverse human values into biosecurity decision-making, and sophisticated socio-environmental models and data capture. The relevance and applicability of these innovations to address threats from pathogens, pests, and weeds in both terrestrial and aquatic ecosystems emphasize the opportunity to build critical mass around interdisciplinary teams at a global scale that can rapidly advance science solutions targeting biosecurity threats., Competing Interests: The authors declare that they have no competing interests., (© 2023 The Author(s).)

- Abstract
Bullying victimization is a risk factor for suicidal ideation, suicide behaviors, and death by suicide in youth. However, not all victims of bullying report suicidal thoughts and behaviors, suggesting that there may be certain subgroups who are at high risk for suicide. Neuroimaging studies suggest that individual differences in neurobiological threat reactivity may contribute to increased vulnerability to suicide, particularly in the context of repeated exposure to bullying. The purpose of the present study was to examine the unique and interactive effects of past-year bullying victimization and neural reactivity to threat on suicide risk in youth. Ninety-one youth (ages 16-19) completed self-report measures of past-year bullying victimization and current suicide risk. Participants also completed a task designed to probe neural reactivity to threat. Specifically, participants passively viewed negative or neutral images during functional magnetic resonance imaging. Bilateral anterior insula (AIC) and amygdala (AMYG) reactivity to threat/negative images (>neutral images) was used to capture threat sensitivity. Greater bullying victimization was associated with increased suicide risk. There was also a bullying by AIC reactivity interaction such that among individuals with high AIC reactivity, greater bullying was associated with increased suicide risk. Among individuals with low AIC reactivity, there was no association between bullying and suicide risk. Results suggest that youth with increased AIC reactivity to threat may be particularly vulnerable to suicide in the context of bullying. These individuals may represent a high-risk group for subsequent suicide behavior and AIC function may be a promising objective prevention target., Competing Interests: Declaration of competing interest All authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier Ltd.

- Abstract
In recent years, there has been increased attention regarding the impact of the media on individuals' perceptions of the criminal justice system, specifically focusing on the CSI effect and forensic evidence. In order to expand this area of research, this article focuses on the impact and interaction of crime-related media-watching habits and victim gender on perceptions of blameworthiness and punishment of both victims and aggressors in sexual assault cases. As expected, results supported the hypothesis that increased media-watching contributed to more stereotypical perceptions of sexual assault cases. However, slight variations observed in blameworthiness and punishment based on victim gender were nonsignificant. Implications for future research are discussed., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Flowers are an important niche for microbes, and microbes in turn influence plant fitness. As flower morphology and biology change rapidly over time, dynamic niches for microbes are formed and lost. Floral physiology at each life stage can therefore influence arrival, persistence and loss of microbial species; however, this remains little understood despite its potential consequences for host reproductive success. Through internal transcribed spacer 1 (ITS1) community profiling, we characterized the effect of transitioning through five floral stages of mānuka (Leptospermum scoparium), from immature bud to spent flower, and subsequent allocation to seed, on the flower-inhabiting fungal community. We found nectar-consuming yeasts from Aureobasidium and Vishniacozyma genera and functionally diverse filamentous fungi from the Cladosporium genus dominated the anthosphere. The candidate core microbiota persisted across this dynamic niche despite high microbial turnover, as observed in shifts in community composition and diversity as flowers matured and senesced. The results demonstrated that floral stages are strong drivers of anthosphere fungal community assembly and dynamics. This study represents the first detailed exploration of fungi through floral development, building on fundamental knowledge in microbial ecology of healthy flowers., (© 2022 The Authors.

- Abstract
Abnormal reward processing is an important yet understudied risk factor for suicide. Recent neuroimaging studies have found that suicidality is associated with abnormal reward-related neural reactivity and connectivity across a wide range of brain regions and circuits. The varying, and oftentimes discrepant, findings have hindered progress in elucidating the neurobiological link between reward processing dysfunction and suicide risk. Some of this variability is likely related to different reward-related paradigms that are utilized across studies. The primary aim of the current study was to address these issues by comparing neural reactivity between youth with and without a history of suicidal ideation during direct manipulation of reward parameters. A total of 108 unmedicated youth, ages 17-19, were classified into two groups: 1) history of suicidal ideation (n = 39) and 2) no history of suicidal ideation (n = 69). All participants completed a novel reward anticipation task probing anticipation of predictable (P-reward) and unpredictable (U-reward) monetary reward. Results revealed that compared with controls, youth with a history of suicidal ideation exhibited increased neural activation in the dorsal anterior cingulate cortex (dACC) and right anterior insula (aINS) during anticipation of U-reward. There were no group differences during anticipation of P-reward. These findings suggest that propensity for suicidal ideation may be related to specific abnormalities during anticipation of U-reward, but not P-reward., Competing Interests: Declaration of competing interest All authors have no conflicts of interest to declare., (Copyright © 2022.

- Abstract
Objective: To investigate any association between expressions of parents' continuing bond with their stillborn baby and bereavement adaptation., Background: Continuing bonds theory suggests that bereaved parents adapt to the loss of their child by sharing and transforming mental representations of the child, allowing them to be integrated into parents' everyday lives. Little is known about the mental health benefits of expressing continuing bonds following stillbirth. This study examined any association between aspects of parents' relationship with their stillborn baby, social support for the relationship, and bereavement adaptation., Methods: Cross-sectional questionnaire study. Parents of stillborn babies ( N =170) completed an online questionnaire examining engagement in continuing bonds expressions; characteristics of parents' relationship with their stillborn baby and their experience of sharing it; social support, and meaning-making. Measures of mental health were included to quantify bereavement adaptation., Results: Regression analyses showed that time since death, meaning-making, engaging with nature, and legacy building are positively linked to bereavement adaptation. Risk factors included inadequate social support for the relationship, a greater desire to share it more freely, an increased sense of integration with baby, and societal pressure to move on., Conclusion: Key aspects of parents' ongoing relationship with their stillborn baby and the social context are related to bereavement adaptation.

- Abstract
Grapevine trunk diseases (GTDs) are a significant problem for New Zealand viticulture. Endophytic actinobacteria are of interest as potential biocontrol agents due to their ability to inhibit plant pathogens and improve plant growth. However, no studies have investigated the diversity of actinobacteria associated with grapevines in New Zealand vineyards and their bioactivity. Actinobacteria diversity in different 'Sauvignon blanc' vine tissues from three vineyards (conventional and organic management, and different vine ages) was assessed using different methods and media. Forty-six endophytic actinobacteria were isolated, with more isolates recovered from roots (n = 45) than leaves (n = 1) and shoot internodes (n = 0). More isolates were recovered from the organic (n = 21) than conventional (n = 8) vineyard, mature (25-year old; n = 21) than young (2-year old; n = 2) vines and using a tissue maceration technique (n = 40). Actinomycete Isolation Agar, International Streptomyces Project 2, and Starch Casein media were effective for actinobacteria isolation. Most of the isolates recovered belonged to Streptomyces, with one isolate identified as Mycolicibacterium. Forty isolates were assessed for antifungal activity and plant growth-promoting (PGP) characteristics. Of these, 13 isolates had antifungal activity against test GTD pathogens (Dactylonectria macrodidyma, Eutypa lata, Ilyonectria liriodendri, Neofusicoccum parvum, and N. luteum). Eighteen isolates exhibited more than one PGP trait; 25siderophore production (n = 25), phosphate solubilization (n = 6), and indole acetic acid production (n = 16). Two strains, Streptomyces sp. LUVPK-22 and Streptomyces sp. LUVPK-30, exhibited the best antifungal and PGP properties. This study revealed the diversity of culturable endophytic actinobacteria from grapevines in New Zealand vineyards and their biocontrol potential against GTD pathogens., (© 2022. The Author(s).)

- Abstract
White clover ( Trifolium repens ) is integral to mixed pastures in New Zealand and temperate agriculture globally. It provides quality feed and a sustainable source of plant-available nitrogen (N) via N-fixation through symbiosis with soil-dwelling Rhizobium bacteria. Improvement of N-fixation in white clover is a route to enhancing sustainability of temperate pasture production. Focussing on seedling growth critical for crop establishment and performance, a population of 120 half-sibling white clover families was assessed with either N-supplementation or N-fixation via inoculation with a commercial Rhizobium strain (TA1). Quantitative genetic analysis identified significant ( p < 0.05) family additive genetic variance for Shoot and Root Dry Matter (DM) and Symbiotic Potential (SP), and Root to Shoot ratio. Estimated narrow-sense heritabilities for above-ground symbiotic traits were moderate (0.24-0.33), and the strong ( r ≥ 0.97) genetic correlation between Shoot and Root DM indicated strong pleiotropy or close linkage. The moderate ( r = 0.47) phenotypic correlation between Shoot DM under symbiosis vs. under N-supplementation suggested plant growth with mineral-N was not a strong predictor of symbiotic performance. At 5% among-family selection pressure, predicted genetic gains per selection cycle of 19 and 17% for symbiotic traits Shoot DM and Shoot SP, respectively, highlighted opportunities for improved early seedling establishment and growth under symbiosis. Single and multi-trait selection methods, including a Smith-Hazel index focussing on an ideotype of high Shoot DM and Shoot SP, showed commonality of top-ranked families among traits. This study provides a platform for proof-of-concept crosses to breed for enhanced seedling growth under Rhizobium symbiosis and is informative for other legume crops., Competing Interests: OE and GC were employed by PGG Wrightson Seeds Ltd. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Weith, Jahufer, Hofmann, Anderson, Luo, Ehoche, Cousins, Jones, Ballard and Griffiths.)

- Abstract
The pet trade and Traditional Chinese Medicine (TCM) consumption are major drivers of global biodiversity loss. Tokay geckos ( Gekko gecko ) are among the most traded reptile species worldwide. In Hong Kong, pet and TCM markets sell tokay geckos while wild populations also persist. To clarify connections between trade sources and destinations, we compared genetics and stable isotopes of wild tokays in local and non-local populations to dried individuals from TCM markets across Hong Kong. We found that TCM tokays are likely not of local origin. Most wild tokays were related to individuals in South China, indicating a probable natural origin. However, two populations contained individuals more similar to distant populations, indicating pet trade origins. Our results highlight the complexity of wildlife trade impacts within trade hubs. Such trade dynamics complicate local legal regulation when endangered species are protected, but the same species might also be non-native and possibly damaging to the environment.

- Abstract
Aim: Botryosphaeriaceae causing stem blight and dieback of blueberry are important pathogens limiting economic production worldwide. This study investigated the pathogenicity and relative virulence of isolates from the Neofusicoccum species commonly associated with blueberries in New Zealand on different tissues and cultivars of blueberries., Methods and Results: Both wounded and non-wounded fruit and flower buds and wounded attached soft green and hard green shoots were susceptible to infection by conidia of Neofusicoccum australe, Neofusicoccum parvum and Neofusicoccum ribis. N. ribis was generally most virulent, followed by N. parvum and then N. australe. Inoculation of potting mixture with N. australe or N. ribis conidia showed that potting mixtures were not a source of inoculum for infection of blueberry roots. Wounded and non-wounded leaf buds, fruit and wounded soft green shoots and hard green shoots of the different cultivars tested were susceptible to infection by N. parvum and N. ribis. Whilst the fruit of all cultivars were similarly infected, infection incidence in inoculated leaf buds was lowest in "Blue Bayou" and "Ocean Blue". Cultivar susceptibility differed when tested on soft green shoots compared with hard green shoots, with shortest lesions developed on "Maru" on soft green shoots, and "Centra Blue" and "Ocean Blue" on hard green shoots., Conclusions: All tested above-ground blueberry tissues, including non-wounded tissue, were susceptible to Neofusicoccum spp. All the cultivars assessed were susceptible to infection, although they varied in their relative susceptibility depending on the tissue assessed., Significance and Impact of the Study: The potential for non-wounded tissue to become infected indicate that fungicides may need to be applied to protect all tissue, not just wounds., (© 2022 The Authors.

- Abstract
Black foot disease is one of the main grapevine root diseases observed worldwide and is especially problematic in New Zealand. Arbuscular mycorrhizal fungi (AMF) have been shown to reduce infection and mitigate the effect of black foot disease on grapevine rootstocks. In contrast to prior studies, which have limited their focus to the effect of one, two or a combination of only a small number of AMF species, this study used whole AMF communities identified from 101-14, 5C and Schwarzmann rootstocks sampled from New Zealand vineyards. The effect of AMF on black foot disease was investigated in a 'home' and 'away' experiment using three commercial grapevine rootstocks. The study produced some evidence that AMF treatments lowered disease incidence at 5 cm and disease severity in vines by 40% to 50% compared to the vines inoculated with the pathogen only. This work also showed that the presence of high disease incidence may have limited the potential disease protective effect of AMF community. However, despite the high disease incidence and severity, AMF inoculation increased vine growth parameters by 60% to 80% compared to the vines inoculated with the pathogen only. This study is the first to provide an understanding on how young grapevine rootstocks inoculated with their 'home' and 'away' AMF communities would respond to challenge with a black foot pathogen species mixture. Further research is required to understand the mechanistic effect of AMF colonization on the increase of grapevine growth parameters under high black foot disease pressure.

- Abstract
Neurological disease and disorders remain a large public health threat. Thus, research to improve early detection and/or develop more effective treatment approaches are necessary. Although there are many common techniques and imaging modalities utilized to study these diseases, existing approaches often require a label which can be costly and time consuming. Matrix-assisted laser desorption ionization (MALDI) imaging mass spectrometry (IMS) is a label-free, innovative and emerging technique that produces 2D ion density maps representing the distribution of an analyte(s) across a tissue section in relation to tissue histopathology. One main advantage of MALDI IMS over other imaging modalities is its ability to determine the spatial distribution of hundreds of analytes within a single imaging run, without the need for a label or any a priori knowledge. Within the field of neurology and disease there have been several impactful studies in which MALDI IMS has been utilized to better understand the cellular pathology of the disease and or severity. Furthermore, MALDI IMS has made it possible to map specific classes of analytes to regions of the brain that otherwise may have been lost using more traditional methods. This review will highlight key studies that demonstrate the potential of this technology to elucidate previously unknown phenomenon in neurological disease., (© 2021.

- Abstract
Aim: Arbuscular mycorrhizal fungi (AMF) are often regarded as non-specific symbionts, but some AMF communities show host preference in various ecosystems including vineyards. Grapevine plants are very responsive to AMF colonization. Although these fungi have potentially significant applications for sustainable agricultural ecosystems, there is a gap in knowledge regarding AMF-grapevine interactions worldwide and especially in New Zealand. This study focused on identifying AMF taxa colonizing grapevines in New Zealand vineyards and investigated the effect of grapevine rootstocks on AMF community diversity and composition., Methods and Results: Denaturing gradient gel electrophoresis (DGGE) and trap cultures were used to characterize the AMF communities. Grapevine roots from three vineyards and nine rootstocks were analysed by DGGE and used in trap cultures for AMF recovery. Trap cultures allowed the recovery of six AMF spore morphotypes that belonged to Ambispora sp., Claroideoglomus sp., Funneliformis sp. and Glomus sp. Bands excised, reamplified and sequenced from the DGGE were assigned to Glomus sp., Rhizophagus sp. and Claroideoglomus sp. The AMF community analyses demonstrated that rootstock significantly (P < 0·05) influenced the AMF community composition in all sites., Conclusions: The study showed that for a comprehensive identification of AMF, both results from trap culture and molecular work were needed and that the rootstock cultivar was the main driver of the arbuscular mycorrhizal community colonizing the roots., Significance and Impact of the Study: This study provides a firm foundation for future research exploring the beneficial use of AMF in enhancing grapevine production and sustainability., (© 2021 The Society for Applied Microbiology.)

34. Being Ostracized Versus Out of the Loop: Redundant or Unique Predictors of Variance in Workplace Outcomes?

Jones EE, Ramsey AT, Wesselmann ED, Rosenthal HJ, and Hesson-McInnis MS
- Abstract
Based on the existing research, being excluded from information (i.e., being out of the loop) produces similar consequences as being ignored or excluded from activities. Consequently, one might wonder whether it is necessary to measure or study different types of exclusion in the workplace context, rather than just assessing a single type of exclusion. The current research investigated the associations between two types of workplace exclusion (i.e., being ostracized and being left out of the loop) and various workplace outcomes, with the purpose of determining whether these different types of exclusion predict unique or redundant variance in these workplace outcomes. In Study 1, we obtained better model fit when we assigned items measuring out-of-the-loop experiences at work to a different factor than items assessing experiences with ostracism at work. In Study 2, we observed that measuring employees' experiences with being out of the loop predicted unique variance in workplace outcomes (e.g., job satisfaction), above and beyond experiences with ostracism at work. Relative weight analyses suggested that both ostracism and out-of-the-loop experiences were equally important predictors of these outcomes. Together, these studies indicate that being ostracized and being left out of the loop may be distinct exclusion experiences and better predictions about workplace outcomes can be made by assessing both types of exclusion. On a practical level, measuring different types of exclusion may prove useful, because organizations may need to implement different interventions for addressing distinct types of exclusion.

- Abstract
Aims: This research aimed to identify factors influencing endophyte community structure in apple shoots and the bioactivity of cultured representatives against the fungal pathogen Neonectria ditissima., Methods and Results: The endophyte community in leaves and stems of the apple cultivars 'Royal Gala' and 'Braeburn' were analysed by a cultivation-independent method (PCR-DGGE) which showed that tissue type, cultivar and site were determinant factors, with the endophyte taxa in 'Royal Gala' more variable than that in 'Braeburn', with leaf endophyte communities typically differing from stems in both cultivars. Seasonal (spring vs autumn) and regional (Nelson vs Hawke's Bay) variations were not obvious in woody stems. A collection of 783 bacterial and 87 fungal endophytes were recovered from leaves and stems of 'Royal Gala', 'Braeburn', 'Scilate' and/or 'Scifresh' from Nelson (nine sites) and Hawke's Bay (five sites) in spring and from Nelson (three sites) in autumn. A dual culture plating assay was used to test their ability to inhibit the mycelial growth of N. ditissima. Thirteen bacterial (mean of percent inhibition ≥20%) and 17 fungal isolates were antagonistic towards N. ditissima. These isolates belonged to the bacterial genera Bacillus and Pseudomonas, and fungal genera Chaetomium, Epicoccum, Biscogniauxia, Penicillium, Diaporthe, Phlyctema and two unidentified fungal isolates., Conclusions: Endophyte communities in apple shoots were determined by tissue type, cultivar and site. Endophytic bacterial and fungal isolates inhibiting N. ditissima growth in vitro were found., Significance and Impact of the Study: These results provided new evidence of factors influencing apple endophyte community in New Zealand. Endophytes with potential to reduce N. ditissima infection were identified, with the potential to be developed into a biocontrol strategy for European canker., (© 2020 The Society for Applied Microbiology.)

- Abstract
Despite the pain ostracism (being excluded and ignored) causes, researchers have minimally investigated factors related to reducing its occurrence. We investigated the association between higher trait mindfulness (the tendency to be attentive to the present moment) and lower engagement in ostracism. In Study 1, employed adults scoring higher on trait mindfulness reported ostracizing coworkers less. In Study 2, participants possessing higher levels of trait mindfulness demonstrated greater inclusion of a fellow group member being ostracized by others in the group. Results suggested that attention, rather than empathy, was the psychological process responsible for greater inclusion of an ostracized group member by mindful individuals. Study 3 supported this conclusion because participants responded similarly to those high in trait mindfulness when they were instructed to pay attention and ensure all players were included equally. Overall, we found that people with higher levels of trait mindfulness are more attentive to targets of ostracism.

- Abstract
Key Message: The quantitative barley leaf rust resistance gene, Rph26, was fine mapped within a H. bulbosum introgression on barley chromosome 1HL. This provides the tools for pyramiding with other resistance genes. A novel quantitative resistance gene, Rph26, effective against barley leaf rust (Puccinia hordei) was introgressed from Hordeum bulbosum into the barley (Hordeum vulgare) cultivar 'Emir'. The effect of Rph26 was to reduce the observed symptoms of leaf rust infection (uredinium number and infection type). In addition, this resistance also increased the fungal latency period and reduced the fungal biomass within infected leaves. The resulting introgression line 200A12, containing Rph26, was backcrossed to its barley parental cultivar 'Emir' to create an F
2 population focused on detecting interspecific recombination within the introgressed segment. A total of 1368 individuals from this F2 population were genotyped with flanking markers at either end of the 1HL introgression, resulting in the identification of 19 genotypes, which had undergone interspecific recombination within the original introgression. F3 seeds that were homozygous for the introgressions of reduced size were selected from each F2 recombinant and were used for subsequent genotyping and phenotyping. Rph26 was genetically mapped to the proximal end of the introgressed segment located at the distal end of chromosome 1HL. Molecular markers closely linked to Rph26 were identified and will enable this disease resistance gene to be combined with other sources of quantitative resistance to maximize the effectiveness and durability of leaf rust resistance in barley breeding. Heterozygous genotypes containing a single copy of Rph26 had an intermediate phenotype when compared with the homozygous resistant and susceptible genotypes, indicating an incompletely dominant inheritance.- Published

- Abstract
Several high-profile cases involving wrongful convictions have featured factually incorrect confessions (i.e., confessions that contradicted case facts). The current research investigated the effects of factually incorrect confessions on juror judgments. In Experiment 1, participants read a trial transcript, containing either no confession, a factually correct confession, or a factually incorrect confession after a 1-hour or 10-hour interrogation. Afterwards, participants judged the coerciveness of the confession, guilt of the suspect and named accomplice, and strength of the prosecution's case. Experiment 2 used confessions with different factual errors and different interrogation lengths. Participants made the same legal judgments. In both experiments, participants rated a factually incorrect confession as more coerced than a factually correct confession. Participants fully discounted factually incorrect confessions when evaluating a defendant's guilt. However, compared to conditions with no confession, participants perceived a named accomplice as guiltier and the prosecution's case as stronger when the defendant provided a factually incorrect confession., Competing Interests: Eric E.

Jarman KL, Kowitt SD, Queen TL, Ranney LM, Kim K, Jones EE, Donovan E, and Goldstein AO
- Abstract
Objectives: The Food and Drug Administration (FDA) is required under the Family Smoking Prevention and Tobacco Control Act to communicate the risks of tobacco use to the public. Little research exists about methods to communicate the constituents of tobacco in a media campaign. This research examines specific strategies to increase effectiveness of a media campaign for cigarette smoking adults about tobacco constituents by including engagement text about smoking cessation and FDA as the source of the campaign., Methods: In an eye tracking study of 211 current cigarette smokers, participants randomly viewed 4 cigarette constituent messages that varied engagement text for quitting (benefits of quitting and quitline number, presence, absence) and by FDA source (presence, absence). After the eye tracking session, participants were asked about recall of the national quitline number and the source of message., Results: Participants in conditions with engagement text were significantly more likely than those in the no engagement conditions to recall the national quitline number. Few participants saw or recalled the FDA source., Conclusions: Engagement text for smoking cessation on constituent communication campaign messages significantly increases recall of the quitline, an important resource for smokers., Competing Interests: Conflict of Interest Statement All authors of this article declare that they have no conflicts of interest.

- Abstract
Lysophosphatidic acid (LPA) levels increase in the cerebrospinal fluid and blood within 24 hours after traumatic brain injury (TBI), indicating it may be a biomarker for subsequent cellular pathology. However, no data exist that document this association after TBI. We, therefore, acquired matrix-assisted laser desorption ionization imaging mass spectrometry data of LPA, major LPA metabolites, and hemoglobin from adult rat brains at 1 and 3 hours after controlled cortical impact injury. Data were semiquantitatively assessed by signal intensity analysis normalized to naïve rat brains acquired concurrently. Gray and white matter pathology was assessed on adjacent sections using immunohistochemistry for cell death, axonal injury, and intracellular LPA, to determine the spatiotemporal patterning of LPA corresponding to pathology. The results revealed significant increases in LPA and LPA precursors at 1 hour after injury and robust enhancement in LPA diffusively throughout the brain at 3 hours after injury. Voxel-wise analysis of LPA by matrix-assisted laser desorption ionization and β-amyloid precursor protein by immunohistochemistry in adjacent sections showed significant association, raising the possibility that LPA is linked to secondary axonal injury. Total LPA and metabolites were also present in remotely injured areas, including cerebellum and brain stem, and in particular thalamus, where intracellular LPA is associated with cell death. LPA may be a useful biomarker of cellular pathology after TBI., (Copyright © 2018 American Society for Investigative Pathology. Published by Elsevier Inc. All rights reserved.)

- Abstract
Diethylnitrosamine-treated male mice were assigned to 4 groups: a casein-based 35% high fat ethanol liquid diet (EtOH), an EtOH diet made with soy protein isolate protein (EtOH/SOY), an EtOH liquid diet supplemented with genistein (EtOH/GEN) and a chow group. EtOH feeding, final concentration 5% (v/v), continued for 16 wks. EtOH increased incidence and multiplicity of basophilic lesions and adenomas compared to the chow group, (p < 0.05). The EtOH/SOY group had reduced adenoma progression when compared to the EtOH and EtOH/GEN group, (p < 0.05). Genistein supplementation had no protective effect. Soy feeding significantly reduced serum ALT concentrations (p < 0.05), decreased hepatic TNFα and CD-14 expression and decreased nuclear accumulation of NFκB protein in EtOH/SOY-treated mice compared to the EtOH group (p < 0.05). With respect to ceramides, high resolution MALDI-FTICR Imaging mass spectrometry revealed changes in the accumulation of long acyl chain ceramide species, in particular C18, in the EtOH group when compared to the EtOH/SOY group. Additionally, expression of acid ceramidase and sphingosine kinase 1 which degrade ceramide into sphingosine and convert sphingosine to sphingosine-1-phosphate (S1P) respectively and expression of S1P receptors S1PR2 and S1PR3 were all upregulated by EtOH and suppressed in the EtOH/SOY group, p < 0.05. EtOH feeding also increased hepatocyte proliferation and mRNA expression of β-catenin targets, including cyclin D1, MMP7 and glutamine synthase, which were reduced in the EtOH/SOY group, p < 0.05. These findings suggest that soy prevents tumorigenesis by reducing inflammation and by reducing hepatocyte proliferation through inhibition of EtOH-mediated β-catenin signaling. These mechanisms may involve blockade of sphingolipid signaling.

- Abstract
We explored conditions under which being in the loop may be an undesirable experience. We tested whether information valence moderates the effects of being in versus out of the loop in four studies. In a pilot study, participants imagined positive and negative events and indicated the degree to which they would like to know this information. In Study 1, participants imagined being in or out of the loop on positive or negative information and indicated how they would feel. In Study 2, participants relived an actual experience when they were in or out of the loop on positive or negative information. In Study 3, participants were in or out of the loop on positive or negative information needed for an upcoming task. These studies provide evidence that being in the loop on negative information can be an unenjoyable experience, threatening fundamental needs and increasing negative affect.

- Abstract
To better understand regional brain glycosphingolipid (GSL) accumulation in Gaucher disease (GD) and its relationship to neuropathology, a feasibility study using mass spectrometry and immunohistochemistry was conducted using brains derived from a GD mouse model (4L/PS/NA) homozygous for a mutant GCase (V394L [4L]) and expressing a prosaposin hypomorphic (PS-NA) transgene. Whole brains from GD and control animals were collected using one hemisphere for MALDI FTICR IMS analysis and the other for quantitation by LC-ESI-MS/MS. MALDI IMS detected several HexCers across the brains. Comparison with the brain hematoxylin and eosin (H&E) revealed differential signal distributions in the midbrain, brain stem, and CB of the GD brain versus the control. Quantitation of serial brain sections with LC-ESI-MS/MS supported the imaging results, finding the overall HexCer levels in the 4L/PS-NA brains to be four times higher than the control. LC-ESI-MS/MS also confirmed that the elevated hexosyl isomers were glucosylceramides rather than galactosylceramides. MALDI imaging also detected differential analyte distributions of lactosylceramide species and gangliosides in the 4L/PS-NA brain, which was validated by LC-ESI-MS/MS. Immunohistochemistry revealed regional inflammation, altered autophagy, and defective protein degradation correlating with regions of GSL accumulation, suggesting that specific GSLs may have distinct neuropathological effects.

- Abstract
Matrix assisted laser desorption ionization imaging mass spectrometry (MALDI IMS) has proven to be a quick, robust, and label-free tool to produce two-dimensional (2D) ion-density maps representing the distribution of a variety of analytes across a tissue section of interest. In addition, three-dimensional (3D) imaging mass spectrometry workflows have been developed that are capable of visualizing these same analytes throughout an entire volume of a tissue rather than a single cross-section. Until recently, the use of Fourier transform ion cyclotron resonance (FTICR) mass spectrometers for 3D volume reconstruction has been impractical due to software limitations, such as inadequate capacity to manipulate the extremely large data files produced during an imaging experiment. Fortunately with recent software and hardware advancements, 3D reconstruction from MALDI FTICR IMS datasets is now feasible. Here we describe the first proof of principle study for a 3D volume reconstruction of an entire mouse lung using data collected on a FTICR mass spectrometer. Each lung tissue section was analyzed with high mass resolution and mass accuracy, and considered as an independent dataset. Each subsequent lung section image, or lung dataset, was then co-registered to its adjacent section to reconstruct a 3D volume. Volumes representing various endogenous lipid species were constructed, including sphingolipids and phosphatidylcholines (PC), and species confirmation was performed with on-tissue collision induced dissociation (CID).

- Abstract
Background: Serum proteomic biomarkers offer a promising approach for early detection of cancer. In this study, we aimed to identify proteomic profiles that could distinguish colon cancer cases from controls using serial prediagnostic serum samples. Methods: This was a nested case-control study of active duty military members. Cases consisted of 264 patients diagnosed with colon cancer between 2001 and 2009. Controls were matched to cases on age, gender, race, serum sample count, and collection date. We identified peaks that discriminated cases from controls using random forest data analysis with a 2/3 training and 1/3 validation dataset. We then included epidemiologic data to see whether further improvement of model performance was obtainable. Proteins that corresponded to discriminatory peaks were identified. Results: Peaks with m/z values of 3,119.32, 2,886.67, 2,939.23, and 5,078.81 were found to discriminate cases from controls with a sensitivity of 69% and a specificity of 67% in the year before diagnosis. When smoking status was included, sensitivity increased to 76% while histories of other cancer and tonsillectomy raised specificity to 76%. Peaks at 2,886.67 and 3,119.32 m/z were identified as histone acetyltransferases while 2,939.24 m/z was a transporting ATPase subunit. Conclusions: Proteomic profiles in the year before cancer diagnosis have the potential to discriminate colon cancer patients from controls, and the addition of epidemiologic information may increase the sensitivity and specificity of discrimination. Impact: Our findings indicate the potential value of using serum prediagnostic proteomic biomarkers in combination with epidemiologic data for early detection of colon cancer.

- Abstract
Purpose: To evaluate early cardiac single photon computed tomography (SPECT) findings after left breast/chest wall postoperative radiation therapy (RT) in the setting of deep inspiration breath hold (DIBH)., Methods and Materials: We performed a prospective single-institution single-arm study of patients who were planned for tangential RT with DIBH to the left breast/chest wall (± internal mammary nodes). The DIBH was done by use of a controlled surface monitoring technique (AlignRT, Vision RT Ltd, London, UK). The RT was given with tangential fields and a heart block. Radiation-induced cardiac perfusion and wall motion changes were assessed by pre-RT and 6-month post-RT SPECT scans. A cumulative SPECT summed-rest score was used to quantify perfusion in predefined left ventricle segments. The incidence of wall motion abnormalities was assessed in each of these same segments., Results: A total of 20 patients with normal pre-RT scans were studied; their median age was 56 years (range, 39-72 years). Seven (35%) patients also received irradiation to the left internal mammary chain, and 5 (25%) received an additional RT field to supraclavicular nodes. The median heart dose was 94 cGy (range, 56-200 cGy), and the median V25
Gy was zero (range, 0-0.1). None of the patients had post-RT perfusion or wall motion abnormalities., Conclusions: Our results suggest that DIBH and conformal cardiac blocking for patients receiving tangential RT for left-sided breast cancer is an effective means to avoid early RT-associated cardiac perfusion defects., (Copyright © 2016 Elsevier Inc.

- Abstract
Farber disease is a rare autosomal recessive disorder caused by acid ceramidase deficiency that usually presents as early-onset progressive visceral and neurologic disease. To understand the neurologic abnormality, we investigated behavioral, biochemical, and cellular abnormalities in the central nervous system of Asah1
P361R/P361R mice, which serve as a model of Farber disease. Behaviorally, the mutant mice had reduced voluntary locomotion and exploration, increased thigmotaxis, abnormal spectra of basic behavioral activities, impaired muscle grip strength, and defects in motor coordination. A few mutant mice developed hydrocephalus. Mass spectrometry revealed elevations of ceramides, hydroxy-ceramides, dihydroceramides, sphingosine, dihexosylceramides, and monosialodihexosylganglioside in the brain. The highest accumulation was in hydroxy-ceramides. Storage compound distribution was analyzed by mass spectrometry imaging and morphologic analyses and revealed involvement of a wide range of central nervous system cell types (eg, neurons, endothelial cells, and choroid plexus cells), most notably microglia and/or macrophages. Coalescing and mostly perivascular granuloma-like accumulations of storage-laden CD68+ microglia and/or macrophages were seen as early as 3 weeks of age and located preferentially in white matter, periventricular zones, and meninges. Neurodegeneration was also evident in specific cerebral areas in late disease. Overall, our central nervous system studies in Asah1P361R/P361R mice substantially extend the understanding of human Farber disease and suggest that this model can be used to advance therapeutic approaches for this currently untreatable disorder., (Copyright © 2017 American Society for Investigative Pathology.

- Abstract
Glycosylated proteins account for a majority of the posttranslation modifications of cell surface, secreted, and circulating proteins. Within the tumor microenvironment, the presence of immune cells, extracellular matrix proteins, cell surface receptors, and interactions between stroma and tumor cells are all processes mediated by glycan binding and recognition reactions. Changes in glycosylation during tumorigenesis are well documented to occur and affect all of these associated adhesion and regulatory functions. A MALDI imaging mass spectrometry (MALDI-IMS) workflow for profiling N-linked glycan distributions in fresh/frozen tissues and formalin-fixed paraffin-embedded tissues has recently been developed. The key to the approach is the application of a molecular coating of peptide-N-glycosidase to tissues, an enzyme that cleaves asparagine-linked glycans from their protein carrier. The released N-linked glycans can then be analyzed by MALDI-IMS directly on tissue. Generally 40 or more individual glycan structures are routinely detected, and when combined with histopathology localizations, tumor-specific glycans are readily grouped relative to nontumor regions and other structural features. This technique is a recent development and new approach in glycobiology and mass spectrometry imaging research methodology; thus, potential uses such as tumor-specific glycan biomarker panels and other applications are discussed., (© 2017 Elsevier Inc.

- Abstract
Leptospermum scoparium or mānuka is a New Zealand native medicinal plant that produces an essential oil with antimicrobial properties. This is the first study to investigate the structure and bioactivity of endophytic bacteria in mānuka by using a combination of cultivation-independent (DGGE) and dependent approaches. A total of 23 plants were sampled across three sites. Plants were considered either immature (3-8 years) or mature (>20 years). The endophyte community structure and richness was affected by plant tissue and bacterial communities became more stable and uniform as plant maturity increased. A total of 192 culturable bacteria were recovered from leaves, stems and roots. Some bacterial isolates showed in vitro biocontrol activity against two fungal pathogens, Ilyonectria liriodendri and Neofusicoccum luteum and a bacterial pathogen, Pseudomonas syringae pv. actinidiae. A high proportion of bacterial endophytes could produce siderophores and solubilise phosphate in vitro. Gammaproteobacteria was the most variable class, representing the majority of cultivated bacteria with bioactivity., Competing Interests: The authors have declared that no competing interests exist.
