- Abstract
Prior research suggests that reducing font clarity can cause people to consider printed information more carefully. The most famous demonstration showed that participants were more likely to solve counterintuitive math problems when they were printed in hard-to-read font. However, after pooling data from that experiment with 16 attempts to replicate it, we find no effect on solution rates. We examine potential moderating variables, including cognitive ability, presentation format, and experimental setting, but we find no evidence of a disfluent font benefit under any conditions. More generally, though disfluent fonts slightly increase response times, we find little evidence that they activate analytic reasoning.

The seven Australasian genera of blister beetles (Coleoptera : Meloidae : Nemognathinae) are reviewed. Included are a key to genera, generic synopses and descriptions of two new genera of Nemognathini, Australozonitis and Pulchrazonitis, as well as a new monotypic tribe Palaestrini, which features a bauplan of male genitalia unique not only to the subfamily Nemognathinae but to the entire family. The genus Palaestra is redefined to include several Australasian, Asian and African species previously assigned to Zonitis. Exceptional variation of male genitalia encountered in the Palaestrini challenges current subfamily definitions, which are partly based on male genitalic structure and correlated sexual behaviour. Generic synopses include synonyms, type species, number of species, geographic distribution, significant references on taxonomy, life history and morphology, and additional notes. Forty-six new combinations are proposed for species previously in Zonitis. Distribution and relationship of tribes within the Nemognathinae, as well as the biogeography of the Australasian Meloidae are outlined and discussed.

- Abstract
Searching for missing or wanted people is a crucial task in our society. Previous work on prospective person memory (PPM) has demonstrated that performance on this type of search task is worse relative to standard prospective memory tasks. Importantly, this process may be further affected by the race of the missing person, yet this has never been tested in laboratory settings. To test the effects of race on PPM, a convenience sample consisting primarily of self-identified Caucasian participants was asked to search for either a Caucasian or an Indian target person while judging the orientation of different Caucasian and Indian faces. Although the tasks were otherwise identical, 89% of Caucasian PPM targets were found while only 53% of Indian targets were found. Furthermore, relative to a control group with no PPM requirements, participants were slower and more error-prone when judging Indian faces relative to White faces, particularly if they were searching for an Indian face. We interpret these results as revealing other-race effects in prospective person memory, highlighting race as a critical factor for finding missing people. Importantly, this also emphasizes the need for real-world search efforts to factor in difficulty differences when people monitor for missing/wanted people from their own or different racial backgrounds. For example, media coverage of missing persons cases could perhaps be distributed more equitably by considering whether the missing person is from a racial minority in that region., (© 2024.

Ferreira L, Sanfins MD, Pinto JD, Skarzynski PH, Skarżyńska MB, and Vieira Biaggio EP
- Abstract
Background: Congenital toxoplasmosis (CT) occurs mainly by primary maternal infection during pregnancy. It is estimated that the incidence of vertical transmission to the fetus is 20% and that infected women are more likely to have a premature birth or low birth weight neonate since there is an association between CT and the rate of premature birth and low birth weight. In addition to severe neurological and ophthalmic consequences, hearing disorders such as hearing loss are also among the clinical manifestations seen in children with CT. Given the above, the objective of this study is to verify what are the auditory disorders seen in children with CT., Methods: This literature review was structured according to the PRISMA statement and based on the terms of Study Target Population, Intervention, Comparison, Outcomes, and Study Types (PICOS). To obtain the studies, the following electronic databases were consulted: PubMed, Web of Science, Scopus, and Lilacs. The combined terms used for the search were: ("auditory evoked potentials" OR "hearing" OR "hearing loss") AND ("congenital toxoplasmosis"). The selection of articles was carried out independently, blindly, by two of the authors, to minimize risk of bias., Results: The search in the databases identified 172 articles, after excluding duplicate articles, 105 studies were identified. From the selection made by reading the titles and abstracts, 11 studies were selected for full-text reading. A total of 94 studies were excluded. An article was selected from the list of references. Therefore, 12 studies were included in the final analysis. It was observed that a significant percentage of studies sought to study the peripheral auditory pathway, verifying the occurrence or association between hearing loss and the presence of congenital infection. Only two studies evaluated the central auditory pathway, using the Brainstem Auditory Evoked Potential (BAEP) and the Frequency Following Response (FFR)., Conclusion: Toxoplasmosis affects not only the peripheral areas but central areas as well. Most studies suggest this pathology as a risk factor for both peripheral and central impairment. Research has found a greater association between CT and mild to moderate hearing loss, in addition to alterations in exams such as BAEP and FFR. These data recommend that CT be reported as a global public health problem and can help assess complications and impacts of hearing disorders as a result of CT. There is a gap about studies that retract the co-occurrence between CT and other Risk Indicators for Hearing Loss (RIHL), such as prematurity, permanence in the intensive care unit, and use of ototoxic medications, lack of longitudinal studies, that accompany the development of hearing and language of children with CT, since the consequences of this infection may be late., 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 © 2024 Ferreira, Sanfins, Pinto, Skarzynski, Skarżyńska and Vieira Biaggio.)

- Abstract
Purpose: To describe the rationale and design of the VOYAGER (NCT05476926) study, which aims to investigate the safety and effectiveness of faricimab and the Port Delivery System with ranibizumab (PDS) for neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME) in clinical practice. VOYAGER also aims to understand drivers of clinical practice treatment outcomes by gaining novel insight into the intersection of treatment regimens, decisions, anatomic outcomes, and vision., Design: Primary data collection, noninterventional, prospective, multinational, multicenter clinical practice study., Participants: At least 5000 patients initiating/continuing faricimab or PDS for nAMD/DME (500 sites, 31 countries)., Methods: Management will be per usual care, with no mandated scheduled visits/imaging protocol requirements. Using robust methodologies, relevant clinical and ophthalmic data, including visual acuity (VA), and data on treatment clinical setting/regimens/philosophies, presence of anatomic features, and safety events will be collected. Routinely collected fundus images will be uploaded to the proprietary Imaging Platform for analysis. An innovative investigator interface will graphically display the patient treatment journey with the aim of optimizing treatment decisions., Main Outcome Measures: Primary end point: VA change from baseline at 12 months per study cohort (faricimab in nAMD and in DME, PDS in nAMD). Secondary end points: VA change over time and per treatment regimens (fixed, treat-and-extend, pro re nata, and other) and number. Exploratory end points: VA change in relation to presence/location of anatomic features that impact vision (fluid, central subfield thickness, fibrosis, atrophy, subretinal hyperreflective material, diabetic retinopathy severity, and disorganization of retinal inner layers) and per treatment regimen/philosophies. The impact of regional and practice differences on outcomes will be assessed as will safety., Results: Recruitment commenced in November 2022 and will continue until late 2027, allowing for up to 5 years follow-up. Exploratory interim analyses are planned annually., Conclusions: VOYAGER is an innovative study of retinal diseases that will assess the effectiveness and safety of faricimab and PDS in nAMD and DME and identify clinician- and disease-related factors driving treatment outcomes in clinical practices globally to help optimize vision outcomes., Financial Disclosures: Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (© 2023 by the American Academy of Ophthalmology.)

- Abstract
Choroidal neovascularization (CNV) is a pathological angiogenesis of the choroidal plexus of the retina and is a key feature in the wet form of age-related macular degeneration. Mononuclear phagocytic cells (MPCs) are known to accumulate in the subretinal space, generating a chronic inflammatory state that promotes the growth of the choroidal neovasculature. However, how the MPCs are recruited and activated to promote CNV pathology is not fully understood. Using genetic and pharmacological tools in a mouse model of laser-induced CNV, we demonstrate a role for the p75 neurotrophin receptor (p75
NTR ) in the recruitment of MPCs, in glial activation, and in vascular alterations. After laser injury, expression of p75NTR is increased in activated Muller glial cells near the CNV area in the retina and the retinal pigmented epithelium (RPE)-choroid. In p75NTR knockout mice (p75NTR KO) with CNV, there is significantly reduced recruitment of MPCs, reduced glial activation, reduced CNV area, and the retinal function is preserved, as compared to wild type mice with CNV. Notably, a single intravitreal injection of a pharmacological p75NTR antagonist in wild type mice with CNV phenocopied the results of the p75NTR KO mice. Our results demonstrate that p75NTR is etiological in the development of CNV.- Published

- Abstract
Objectives: to describe reference values for the electrophysiological thresholds obtained in the frequency-specific Auditory Brainstem Response (fsABR) with the NB CE-Chirp® LS and NB iChirp stimuli in hearing infants and to compare the variables: Minimum Levels of Response (MLR), latency, amplitude and examination time., Methods: the sample consisted of 74 full-term infants, with a mean age of 23.11 days, 29 females and 45 males. The participants underwent fsABR at the frequencies of 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz, to measure the MLR with the NB CE-Chirp® LS stimulus in the Eclipse equipment, and with the NB iChirp stimulus in the SmartEP, all in natural sleep and performed in the same session. The waveforms were evaluated by judges and later, for the comparison of thresholds and examination time, analyzed with the Wilcoxon test. To compare latency and amplitude, the Student's T Test and ANOVA were used for the same variables, but with the same stimulus. The Kruskal-Wallis test was used to compare the examination time at the different frequencies., Results: The MLR and latency at 500 Hz and 1000 Hz showed a statistically significant difference between the stimuli, with lower thresholds and higher latencies for the NB iChirp. Higher amplitudes were obtained with the NB iChirp stimulus. The average examination time for the threshold investigation in the four frequencies was 40 min for each ear., Conclusion: it was possible to present reference values for the MLR and latencies for the NB CE-Chirp® LS and NB iChirp stimuli for hearing infants. In addition, with the NB iChirp, the latency of the responses was influenced by the frequency, but it was the stimulus that provided greater amplitudes. With the NB CE-Chirp® LS, the frequency did not influence latency, except at 500 Hz, and the stimulus provided recordings that facilitated the visualization of wave V. There was no difference in the examination time between the stimuli, nor between the test frequencies., Competing Interests: Declaration of competing interest The authors have declared that no competing interests exist., (Copyright © 2022 Elsevier B.V.

- Abstract
Purpose: To describe the audiological characteristics and the type of intervention chosen on unilateral hearing loss cases in children and adolescents as well as to analyze correlations between the degree of hearing loss, the indication and the use of electronic devices., Methods: Observational, descriptive and retrospective study, carried out with information of 34 medical records from children and adolescents with unilateral hearing loss, assessed by two auditory rehabilitation services of medium complexity, throughout 2016 to 2019. Descriptive and Inferential statistical analysis were performed with the data., Results: A predominance of profound sensorineural unilateral hearing loss in the right ear, of pre-lingual character, with 20.6% of malformations. The most adopted intervention was the hearing aid indication, although its use is low, regardless of the degree of the hearing loss. An association was found between the degree of the hearing loss and the healthcare professionals in indicating the use of the devices., Conclusion: The indication of hearing aids is the most frequent and this decision is influenced by the degree of the hearing loss, in which the devices are mostly indicated for mild to severe losses, with bigger divergence of conduct for profound hearing losses.

- Abstract
During childhood, neuronal modifications occur so that typical childhood communicative development occurs. This work aims to contribute to the understanding of differences in the speech encoding of infants and school-age children by assessing the effects of child development, in different phases of early childhood, on the encoding of speech sounds. There were 98 subjects of both sexes, aged from 1 day to 8 years and 9 months who participated in the study. All subjects underwent a Frequency Following Response (FFR) assessment. A regression and linear correlation showed the effects of age in the FFR components, i.e., significant decrease in the latency and increased amplitude of all FFR waves with age. An increase in the slope measure was also observed. Younger infants require more time and show less robust responses when encoding speech than their older counterparts, which were shown to have more stable and well-organized FFR responses., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Objective: to investigate the use of the iChirp stimulus in the infant's audiological diagnosis compared to stimuli typically used in the ABR in infants, in addition to suggesting reference values for the assessment of this population., Methods: 62 infants participated in the study, 29 females and 33 males. The subjects underwent the recording of the Auditory Brainstem Response in the Smart Ep equipment, with the stimuli click, iChirp-broadband, tone burst and iChirp-narrowband, which were presented at three levels of intensity (20 dB, 40 dB and 60 dB) and, for tone burst and iChirp-narrowband stimuli, at different frequencies (0.5, 1 k, 2 k and 4 KHz). The data were later analyzed using Student's t-test., Results: In general, the iChirp-broadband and iChirp-narrowband stimuli showed higher latency values and greater amplitudes when compared to click and tone burst stimuli. Furthermore, better signal-to-noise ratios were observed when contrasting iChirp-narrowband with tone burst. Additionally, reference values were established for the assessment of ABR in infants with the iChirp-broadband and iChirp-narrowband in the Smart-Ep equipment., Conclusion: The iChirp stimulus appears to be promising in the infant's audiological diagnosis, as its use promoted greater amplitudes and better wave morphology, which facilitates to mark the waveforms and provides greater efficiency in the investigation of the auditory thresholds. The indication of normative data also enables the clinical use of these stimuli in the infant's audiological diagnosis., (Copyright © 2022 Elsevier B.V. All rights reserved.)

- Abstract
Remembering to fulfill an intention at a later time often requires people to monitor the environment for cues that it is time to act. This monitoring involves the strategic allocation of attentional resources, ramping attention up more in some contexts than others. In addition to interfering with ongoing task performance, flexibly shifting attention may affect whether task-irrelevant information is later remembered. In the present investigation, we manipulated contextual expectations in event-related prospective memory (PM) to examine the consequences of flexible attention allocation on incidental memory. Across two experiments, participants completed a color-matching task while monitoring for ill-defined (Experiment 1) or specific (Experiment 2) PM targets. To manipulate contextual expectations, some participants were explicitly told about the trial types in which PM targets could (or not) appear, while others were given less precise or no expectations. Across experiments, participants' color-matching decisions were slower in high-expectation trials, relative to trials when targets were not expected. Additionally, participants had better incidental memory for PM-irrelevant items from high-expectation trials, but only when they received explicit contextual expectations. These results confirm that participants flexibly allocate attention based on explicit trial-by-trial expectations. Furthermore, the present study indicates that greater attention to item identity yields better incidental memory even for PM-irrelevant items, irrespective of processing time., (© 2021.

- Abstract
Domain-specific expertise changes the way people perceive, process, and remember information from that domain. This is often observed in visual domains involving skilled searches, such as athletics referees, or professional visual searchers (e.g., security and medical screeners). Although existing research has compared expert to novice performance in visual search, little work has directly documented how accumulating experiences change behavior. A longitudinal approach to studying visual search performance may permit a finer-grained understanding of experience-dependent changes in visual scanning, and the extent to which various cognitive processes are affected by experience. In this study, participants acquired experience by taking part in many experimental sessions over the course of an academic semester. Searchers looked for 20 categories of targets simultaneously (which appeared with unequal frequency), in displays with 0-3 targets present, while having their eye movements recorded. With experience, accuracy increased and response times decreased. Fixation probabilities and durations decreased with increasing experience, but saccade amplitudes and visual span increased. These findings suggest that the behavioral benefits endowed by expertise emerge from oculomotor behaviors that reflect enhanced reliance on memory to guide attention and the ability to process more of the visual field within individual fixations.

- Abstract
When searching for objects in the environment, observers necessarily encounter other, nontarget, objects. Despite their irrelevance for search, observers often incidentally encode the details of these objects, an effect that is exaggerated as the search task becomes more challenging. Although it is well established that searchers create incidental memories for targets, less is known about the fidelity with which nontargets are remembered. Do observers store richly detailed representations of nontargets, or are these memories characterized by gist-level detail, containing only the information necessary to reject the item as a nontarget? We addressed this question across two experiments in which observers completed multiple-target (one to four potential targets) searches, followed by surprise alternative forced-choice (AFC) recognition tests for all encountered objects. To assess the detail of incidentally stored memories, we used similarity rankings derived from multidimensional scaling to manipulate the perceptual similarity across objects in 4-AFC (Experiment 1a) and 16-AFC (Experiments 1b and 2) tests. Replicating prior work, observers recognized more nontarget objects encountered during challenging, relative to easier, searches. More importantly, AFC results revealed that observers stored more than gist-level detail: When search objects were not recognized, observers systematically chose lures with higher perceptual similarity, reflecting partial encoding of the search object's perceptual features. Further, similarity effects increased with search difficulty, revealing that incidental memories for visual search objects are sharpened when the search task requires greater attentional processing.

- Abstract
In many visual search tasks (e.g., cancer screening, airport baggage inspections), the most serious search targets occur infrequently. As an ironic side effect, when observers finally encounter important objects (e.g., a weapon in baggage), they often fail to notice them, a phenomenon known as the low-prevalence effect (LPE). Although many studies have investigated LPE search errors, we investigated the attentional consequences of successful rare target detection. Using an attentional blink paradigm, we manipulated how often observers encountered the first serial target (T1), then measured its effects on their ability to detect a following target (T2). Across two experiments, we show that the LPE is more than just an inflated miss rate: When observers successfully detected rare targets, they were less likely to spot subsequent targets. Using pupillometry to index locus-coeruleus (LC) mediated attentional engagement, Experiment 2 confirmed that an LC refractory period mediates the attentional blink (`Nieuwenhuis, Gilzenrat, Holmes, & Cohen, 2005, Journal of Experimental Psychology: General, 134[3], 291-307), and that these effects emerge relatively quickly following T1 onset. Moreover, in both behavioral and pupil analyses, we found that detecting low-prevalence targets exacerbates the LC refractory period. Consequences for theories of the LPE are discussed.

- Abstract
Recognition memory is often viewed as the end-product of discrete cognitive events, involving the combination of latent operations such as the assessment of memory strength, the decision time, and the memory judgement. Recently, researchers have begun using the physical dynamics of memory retrieval to provide insight into the dynamic, possibly non-discrete, processes that underlie memory decisions. In this study, the underlying distributional properties of targets and lures were manipulated by populating lists with items drawn from either homogeneous or heterogeneous word frequency and context variability ranges. In all conditions, participants' x-, y- mouse coordinates were recorded as they processed test items, allowing estimates of response dynamics (e.g., initial deviation and area under the curve [AUC]), and eventual old/new responses. The stimulus manipulations affected the distribution shapes and, to a greater degree, the placements of subjective confidence thresholds. We observed tight correspondences between confidence and AUC for both hits and correct rejections. We interpret these results within dynamic models of recognition memory.

- Abstract
When observers search for multiple (rather than singular) targets, they are slower and less accurate, yet have better incidental memory for nontarget items encountered during the task (Hout & Goldinger, 2010). One explanation for this may be that observers titrate their attention allocation based on the expected difficulty suggested by search cues. Difficult search cues may implicitly encourage observers to narrow their attention, simultaneously enhancing distractor encoding and hindering peripheral processing. Across three experiments, we manipulated the difficulty of search cues preceding passive visual search for real-world objects, using a Rapid Serial Visual Presentation (RSVP) task to equate item exposure durations. In all experiments, incidental memory was enhanced for distractors encountered while participants monitored for difficult targets. Moreover, in key trials, peripheral shapes appeared at varying eccentricities off center, allowing us to infer the spread and precision of participants' attentional windows. Peripheral item detection and identification decreased when search cues were difficult, even when the peripheral items appeared before targets. These results were not an artifact of sustained vigilance in miss trials, but instead reflect top-down modulation of attention allocation based on task demands. Implications for individual differences are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

- Abstract
To improve maintenance of task-relevant information in visual working memory (VWM), previously encoded, but no longer relevant, information can be suppressed or forgotten. However, it is unclear whether a cue directing attention to a subset of stimuli leads to complete forgetting for non-cued stimuli. The current study utilized a novel method of testing to-be forgotten information to determine if the effectiveness of forgetting differs depending on the type of encoded stimuli. Participants performed a directed forgetting change detection task, and importantly, the changed stimulus could be a novel stimulus or a to-be-forgotten stimulus. Stimulus type (colors, objects, or shapes) was manipulated across two experiments. Results suggest that a cue benefits memory for to-be-remembered information, but performance is not equivalent to never encoding to-be-forgotten information. Furthermore, the type of encoded information impacts the extent of forgetting., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Aim: This integrative review aims to summarize the evidence regarding the health-related quality of life, psychological well-being, and the relevant influencing factors in men with benign prostatic hyperplasia., Methods: An integrative published work review was adopted. Articles published in English from 2002 to 2014 that addressed the variables of health-related quality of life, psychological well-being, or the relevant influencing factors in men with benign prostatic hyperplasia were included., Results: Of the 4708 articles retrieved, 16 were deemed relevant. Analysis of the published work suggests that benign prostatic hyperplasia has a negative impact on health-related quality of life, citing two major predictive factors: lower urinary tract symptoms and medical management. The psychological well-being of men with benign prostatic hyperplasia remains inconclusive as very limited studies have been conducted to investigate this aspect in these men. Limited studies collectively investigate the relationship among concepts such as health-related quality of life, psychological well-being, and sociodemographic and clinical factors related to benign prostatic hyperplasia., Conclusion: This review highlights the need to conduct further study on health-related quality of life and the psychological well-being of patients with benign prostatic hyperplasia, especially in an Asian context. Such efforts promote patient-centric care and improve patient satisfaction through incorporating the concept of health-related quality of life into clinical practices., (© 2016 Japan Academy of Nursing Science.)

- Abstract
Prior research suggests that reducing font clarity can cause people to consider printed information more carefully. The most famous demonstration showed that participants were more likely to solve counterintuitive math problems when they were printed in hard-to-read font. However, after pooling data from that experiment with 16 attempts to replicate it, we find no effect on solution rates. We examine potential moderating variables, including cognitive ability, presentation format, and experimental setting, but we find no evidence of a disfluent font benefit under any conditions. More generally, though disfluent fonts slightly increase response times, we find little evidence that they activate analytic reasoning., ((c) 2015 APA, all rights reserved).)

- Abstract
Aims and Objectives: To examine the health-related quality of life and psychological well-being of patients with benign prostatic hyperplasia and identify the predictive factors of health-related quality of life., Background: Benign prostatic hyperplasia is highly prevalent in ageing men and causes bothersome lower urinary tract symptoms, which has a negative impact on their health-related quality of life. The current practice of managing benign prostatic hyperplasia focuses on relieving physical symptoms. However, the impact of benign prostatic hyperplasia on the patients' health-related quality of life and psychological well-being remains understudied, especially in the Asian population., Design: A descriptive correlational survey study., Methods: A convenience sample of 97 patients with benign prostatic hyperplasia was recruited at an outpatient urology clinic of a tertiary hospital in Singapore. The health-related quality of life, lower urinary tract symptoms and psychological well-being of the participants were assessed using the 12-item Short-Form Health Survey, International Prostate Symptom Score and the Hospital Anxiety and Depression Scale, respectively., Results: The health-related quality of life scores were low with physical and mental health component scores of 47·0 and 48·9, respectively, as assessed by the 12-item Short-Form Health Survey. There was a high prevalence of anxiety (10·3%) and depression (21·6%). Correlation analysis revealed significantly negative relationships between lower urinary tract symptoms, anxiety, depression and physical and mental health dimensions of the 12-item Short-Form Health Survey. Multiple linear regression analysis further identified that postvoid residual urine and lower urinary tract symptoms were predictive factors of the physical health dimension, whereas anxiety and depression were predictive factors of the mental health dimension of the 12-item Short-Form Health Survey., Conclusions: The health-related quality of life of patients with benign prostatic hyperplasia was poor, and their psychological well-being was severely affected. Postvoid residual urine, lower urinary tract symptoms, anxiety and depression were identified to be significant predictive factors of the health-related quality of life of patients with benign prostatic hyperplasia., Relevance to Clinical Practice: Findings from this study provide useful evidence-based information for healthcare professionals in the development and implementation of effective and culturally sensitive interventions to improve the health-related quality of life and psychological well-being of patients with benign prostatic hyperplasia., (© 2014 John Wiley & Sons Ltd.)

- Abstract
Chalcidoidea (Hymenoptera) is extremely diverse with an estimated 500 000 species. We present the first phylogenetic analysis of the superfamily based on both morphological and molecular data. A web-based, systematics workbench mx was used to score 945 character states illustrated by 648 figures for 233 morphological characters for a total of 66 645 observations for 300 taxa. The matrix covers 22 chalcidoid families recognized herein and includes 268 genera within 78 of 83 subfamilies. Morphological data were analysed alone and in combination with molecular data from ribosomal 18S (2105 bp) and 28S D2-D5 expansion regions (1812 bp). Analyses were analysed alone and in combined datasets using implied-weights parsimony and likelihood. Proposed changes in higher classification resulting from the analyses include: (i) recognition of Eriaporidae, revised status; (ii) recognition of Cynipencyrtidae, revised status; (iii) recognition of Azotidae, revised status; (iv) inclusion of Sycophaginae in Agaonidae, revised status; (v) reclassification of Aphelinidae to include Aphelininae, Calesinae, Coccophaginae, Eretmocerinae and Eriaphytinae; (vi) inclusion of Cratominae and Panstenoninae within Pteromalinae (Pteromalidae), new synonymy; (vii) inclusion of Epichrysomallinae in Pteromalidae, revised status. At a higher level, Chalcidoidea was monophyletic, with Mymaridae the sister group of Rotoitidae plus the remaining Chalcidoidea. A eulophid lineage was recovered that included Aphelinidae, Azotidae, Eulophidae, Signiphoridae, Tetracampidae and Trichogrammatidae. Eucharitidae and Perilampidae were monophyletic if Eutrichosomatinae (Pteromalidae) was included, and Eupelmidae was monophyletic if Oodera (Pteromalidae: Cleonyminae) was included. Likelihood recovered a clade of Eupelmidae + (Tanaostigmatidae + (Cynipencyrtus + Encyrtidae). Support for other lineages and their impact on the classification of Chalcidoidea is discussed. Several life-history traits are mapped onto the new phylogeny., (© 2012 Her Majesty the Queen in Right of Canada Cladistics © The Willi Hennig Society 2013 Reproduced with the permission of the Minister of Agriculture and Agri-Food Canada.)

- Abstract
This is the first study of Australian blister beetle larvae. The first-instar larva of one species of the endemic genus Palaestra Laporte de Castelnau, 1840, is described as well as those of other phoretic species without adult association and consequently unplaced to genus. Two main larval types (Groups 1 and 2) are recognised, as are distinct morphotypes within each group. Although both groups are assignable to the Nemognathinae, they are characterised by traits not paralleled by subfamily representatives from other regions of the world. Group 1, which includes Palaestra , is the more distinctive, whereas Group 2 shares most characteristics with members of the cosmopolitan tribe Nemognathini. A tabular comparison of larval groups and morphotypes is included., (© 2010 The Authors. Journal compilation © 2010 Australian Entomological Society.)

- Abstract
Hobnail hemangioma (HH) is a rare benign vascular neoplasm reported as a distinctive small benign, solitary vascular neoplasm of the superficial and mid-dermis occurring on the face, trunk, or extremities of young or middle-aged adults. The oral manifestations are quite uncommon, with only three cases reported in the English language literature. The following case refers to a 38-year-old woman with a small nodule on the hard palatal mucosa. Histological findings showed a biphasic growth pattern of irregularly dilated vascular structures in the superficial mucosa, lined by epithelioid endothelial cells with a hobnail appearance, with neoplastic vessels observed in deeper parts of the lesion. In the oral cavity, the differential diagnosis includes hemangioma, melanoma, and Kaposi's sarcoma, whose clinical and histological features may be confused with those of HH.
