This study explores four 1.5-generation Korean-New Zealanders' perceptions of bilingualism, heritage language (HL) competence, and identity. Drawing on interview data, the study shows that the participants were strongly connected to their ethnic group and strove to accept and strengthen their hyphenated Korean-New Zealander identities through foregrounding their bilingual and bicultural competence. In addition to their Korean use at home, socializing with other Korean speakers at church and in peer groups aided their learning of a wide range of registers in context, while providing culturally sensitive places for the participants to explore their identities. Nevertheless, the study also found that the participants encountered racial and linguistic hierarchical structures from which they were marginalized, which delayed their construction of positive bilingual identities. The findings enable a deeper understanding of how family-internal and family-external factors shape immigrant children's identities, and suggest that substantial institutional and societal support are needed to foster immigrant children's bilingualism and biculturalism.

This narrative case study examines the identity development of two mixed-heritage (Korean/White and Korean/Japanese) university students in relation to Korean as a heritage language (HL) in New Zealand. The narratives of the two participants (Mia and Hannah) revealed that they grew up with different levels of exposure to the HL, which impacted their HL proficiency, and experienced different struggles with identity construction. While Mia's White appearance helped her explore multiple ethnic/cultural identities, Hannah was deemed completely non-White by White New Zealanders, assigned a minority "Asian" identity, and subjected to racial discrimination. The dominant group's confusion about intra-race mixedness and perceptions of Hannah as non-mixed complicated her situation. Hannah had little access to a majority heritage (New Zealander) identity, but also found her specific heritage identities occluded by an imposed single ("Asian") identity. Nonetheless, on entering university both participants showed a strong desire to embrace their Koreanness through HL education or socialization with coethnic peers. HL learning played a crucial role in their construction of mixed-heritage identity; for Mia, the HL was valuable social capital, while for Hannah, the HL was a means of claiming her ethnic identity. This study highlights the complexity and plurality of mixed-heritage identities and offers implications for educators.

This article explores language ideologies, heritage language (HL) use, and identity construction among 1.5-generation Korean immigrants in New Zealand. Drawing on interview data, the study shows how language ideologies and identities influence these immigrants' language use and investment. All participants reported speaking Korean with their parents and adult members of their ethnic community, considering the use of English with these interlocutors to be inappropriate. The participants associated Korean language with their ethnocultural identities and viewed proficiency in their HL as essential in claiming Koreanness. The majority also reported 'mixing' Korean and English with siblings and friends, a practice they perceived as part of a shared 'Kowi' (Korean-Kiwi) identity. The participants' investment in HL use and maintenance was strongly tied to gaining cultural capital as Koreans in New Zealand; at the same time, they showed a lack of investment in further HL development. Constructing their identities as diasporic subjects, they did not regard native-like Korean fluency or advanced literacy skills as necessary or contributing to their socioeconomic capital. Based on the findings, this study offers implications for school administrators and policy makers in terms of how to support immigrants' HL development for the benefit of individuals, families, communities, and the nation.

This narrative study focuses on how Gina, a Korean learner with a Korean immigrant mother and a European-descent New Zealander father, constructed her identities and engaged with Korean as a heritage language (HL) before, during, and after studying abroad in Korea. Gina's transformative experiences illustrate the links between HL learning and learners' understanding of themselves in racial/ethnic/cultural terms. The study highlights raciolinguistic ideologies' complex influence on the HL development and identity (re)construction of learners who consider themselves to have multiple racial/ethnic/cultural heritages. Although Gina's HL learner identity hampered her classroom education during study abroad, her family background provided her opportunities outside the classroom that strengthened her sense of belonging and encouraged her (re)construction of her identities. The study provides practical implications for study-abroad program developers and educators concerning the raciolinguistic ideologies that HL learners who identify as having multiple heritages might bring to their HL learning and participation in study-abroad programs. Being aware of raciolinguistic ideologies, preparing students for how their own and others' ideologies might impact their experiences during study abroad, and providing the means for multiheritage HL learners to share their experiences could all contribute positively to these learners' continued identity (re)construction, HL development, and study-abroad experiences.

Drawing on autobiographical narratives of a second-generation Korean heritage language (HL) student who grew up in Auckland, New Zealand, this study examines the role of university study in HL students' identity development. In her narratives, the participant describes feeling inferior about her Korean HL and culture as a child but finding that university offered space for the (re)construction and positive reinforcement of her HL and cultural identities over time. The university provided her with a multicultural community, and HL and other identity- and heritage-culture-related courses, which enabled her both to (re)construct her sense of self and to critically examine the challenges she faced in a White European-dominated society. The findings shed light on second-generation immigrant-background students' HL and related identity development processes, and the importance of creating bilingual and bicultural educational spaces in tertiary education for their ongoing identity development.

Drawing on Bourdieu's concept of linguistic capital and Darvin and Norton's notion of investment, this study explores heritage language (HL) use among 1.5-generation Korean immigrants in the New Zealand workplace. The data were collected through interviews with heritage speakers of Korean working in diverse fields in Auckland. The majority of the participants had some degree of regular HL use at work, albeit limited to interactions with monolingual clients rather than with bilingual clients or colleagues. Some participants hesitated to use Korean in these situations because of their self-perceived imperfect HL skills and language anxiety. Moreover, although they perceived their HL as useful, they did not consider it a highly valuable form of linguistic capital in their professional lives. While they realized that HL proficiency would be valuable if they were to return to Korea for career-related purposes, none of them had plans to do so. Consequently, despite a stated interest in improving their HL proficiency, they did not actually invest in the HL. This study sheds light on the complex relationships between language ideologies, identity, and investment in HL learning in the context of diaspora, and offers pedagogical implications for HL education.

Background: An increasing number of older patients are undergoing emergency laparotomy (EL). Frailty is thought to contribute to adverse outcomes in this group. The best method to assess frailty and impacts on long‐term mortality and other important functional outcomes for older EL patients have not been fully explored. Methods: A prospective multicenter study of older EL patients was conducted across four hospital sites in New Zealand from August 2017 to September 2022. The Clinical Frailty Scale (CFS) was used to measure frailty—defined as a CFS of ≥5. Primary outcomes were 30‐day and one‐year mortality. Secondary outcomes were postoperative morbidity, admission for rehabilitation, and increased care level on discharge. A multivariate logistic regression analysis was conducted, adjusting for age, sex, and ethnicity. Results: A total of 629 participants were included. Frailty prevalence was 14.6%. Frail participants demonstrated higher 30‐day and 1‐year mortality—20.7% and 39.1%. Following adjustment, frailty was directly associated with a significantly increased risk of short‐ and long‐term mortality (30‐day aRR 2.6, 95% CI 1.5, 4.3, p = <0.001, 1‐year aRR 2.0, 95% CI 1.5, 2.8, p < 0.001). Frailty was correlated with a 2‐fold increased risk of admission for rehabilitation and propensity of being discharged to an increased level of care, complications, and readmission within 30 days. Conclusion: Frailty was associated with increased risk of postoperative mortality up to 1‐year and other functional outcomes for older patients undergoing EL. Identification of frailty in older EL patients aids in patient‐centered decision‐making, which may lead to improvement in outcomes. [ABSTRACT FROM AUTHOR]

Purpose: This paper highlights important lessons for co-innovation drawn from three ex-post case study innovation projects implemented within three sub-sectors of the primary industry sector in New Zealand. Design/methodology/approach: The characteristics that fostered co-innovation in each innovation project case study were identified from semi-structured interviews conducted with key stakeholders in each project, iterative discussions to confirm the findings and secondary document analysis. Common themes from the three cases are examined in relation to innovation system structure and function analysis and agricultural innovation system (AIS) literature. This study builds on the literature attempting to overcome methodological challenges in the applied AIS research space. Findings: The findings have implications for co-innovation in practice; that there needs to be network-level capability and legitimacy, an understanding of priorities between actors, and adequate resources, to ensure proposed outcomes are likely to be attained. Practical implications: Practically, project leaders need to ensure they embed an appropriate mix of actors in the research program and they also need to create and encourage room for open and honest dialogue between these actors to develop a shared vision of the future. Theoretical implications: A conceptual model is developed to highlight and simplify lessons that can inform future projects involving co-innovation approaches to create value in the primary industries and AIS more generally. This model is unique to the applied AIS research space and provides new insights on enhancing the potential value of a co-innovation approach. Originality/value: The paper adds to current scholarly debates and provides insight to key actions stakeholders need to take to foster co-innovation processes for successful outcomes in extension.

The phlorotannin-polycaprolactone-coated endotracheal tube (PP tube) has been developed with the aim of preventing tracheal stenosis that can result from endotracheal intubation, a factor that can lead to a serious airway obstruction. Its preventive efficacy has been assessed through both in vitro and in vivo investigations. However, there is a lack of studies concerning its biocompatibility and sub-chronic toxicity in animal models, a crucial factor to ensure the safety of its usage as a functional endotracheal tube. Thus, this study aimed to evaluate the biocompatibility and sub-chronic (13 weeks) toxicity of the PP tube through L929 cell line and diverse in vivo models. The cytotoxicity testing was performed using the extracts of PP tube on L929 cells for 72 h. Furthermore, other tests conducted on animal models, including ICR mice (acute systemic toxicity), New Zealand white rabbit (intradermal reactivity and pyrogen tests), guinea pig (maximization sensitization), and Sprague Dawley rats (sub-chronic toxicity). In both biocompatibility and sub-chronic toxicity analyses, no significant adverse effects are observed in the groups exposed to the PP tube, when compared to control group. Altogether, the findings suggested that the PP tube exhibits relative non-toxic and safety, supporting its suitability for clinical usage. However, extended periods of intubation may produce mild irritant responses, highlighting the clinical caution of limiting intubation duration to less than 13 weeks. [ABSTRACT FROM AUTHOR]

Peri-implantitis is an inflammatory lesion leading to bone destruction resulting from bacterial infection and biofilm formation. Treatments of peri-implantitis aim at bacterial controls and decontamination to promote re-osseointegration. The present study aimed to assess the decontamination of biofilm and the osseointegration of titanium discs in a rabbit tibia model. Discs were immersed in culture medium inoculated with Staphylococcus aureus and incubated at 37 °C for 24 h and allocated to different treatments (n = five per group). The decontamination methods were an air-polishing system, 0.12% chlorhexidine rinse, and Er:Yag laser treatments. Each disc from the experimental groups was observed using scanning electron micrography. The rest of the discs were then implanted in four male New Zealand rabbits. Histological and radiographic evaluations were performed. For the quantification of bone density in radiographic data, the fractal dimension (FD) and mean grayscale value (GV) were measured. The Kruskal–Wallis test was used to compare bone density (p < 0.05). Statistically significant differences in FD were observed between the air-polishing treatment with chlorhexidine rinse and the air-polishing treatment with chlorhexidine rinse and Er:Yag laser treatment compared to the contaminated group (p < 0.05). Also, there were statistically significant differences in the results obtained for the group undergoing air-polishing treatment with chlorhexidine rinse and Er:Yag laser treatment compared to the contaminated group (p < 0.05). The decontamination method using air polishing treatment, chlorhexidine rinse, and Er:Yag treatment showed favorable osseointegration with good bone quality. [ABSTRACT FROM AUTHOR]

Overgrowth of long bones was noted in pediatric patients who underwent anterior cruciate ligament reconstruction. Hyperaemia during creating a metaphyseal hole and the microinstability made by the drill hole may induce overgrowth. This study aimed to determine whether metaphyseal hole creation accelerates growth and increases bone length and compare the effects of growth stimulation between metaphyseal hole creation and periosteal resection. We selected 7- to 8-week-old male New Zealand white rabbits. Periosteal resection (N = 7) and metaphyseal hole creation (N = 7) were performed on the tibiae of skeletally immature rabbits. Seven additional sham controls were included as age-matched controls. In the metaphyseal hole group, the hole was made using a Steinman pin at the same level of periosteal resection, and the cancellous bone beneath the physis was removed by curettage. The vacant space in the metaphysis below the physis was filled with bone wax. Tibiae were collected 6 weeks after surgery. The operated tibia was longer in the metaphyseal hole group (10.43 ± 0.29 cm vs. 10.65 ± 0.35 cm, P = 0.002). Overgrowth was higher in the metaphyseal hole group (3.17 ± 1.16 mm) than in the sham group (− 0.17 ± 0.39 mm, P < 0.001). The overgrowth in the metaphyseal hole group was comparable to that in the periosteal resection group (2.23 ± 1.52 mm, P = 0.287). In rabbits, metaphyseal hole creation and interposition with bone wax can stimulate long bone overgrowth, and the amount of overgrowth is similar to that seen in periosteal resection.

We examined whether recombinant human bone morphogenetic protein-2 (rhBMP-2) when applied to collagen membranes, would reinforce them during guided bone regeneration. Four critical cranial bone defects were created and treated in 30 New Zealand white rabbits, including a control group, critical defect only; group 1, collagen membrane only; group 2, biphasic calcium phosphate (BCP) only; group 3, collagen membrane + BCP; group 4, collagen membrane with rhBMP-2 (1.0 mg/mL); group 5, collagen membrane with rhBMP-2 (0.5 mg/mL); group 6, collagen membrane with rhBMP-2 (1.0 mg/mL) + BCP; and group 7, collagen membrane with rhBMP-2 (0.5 mg/mL) + BCP. After a 2-, 4-, or 8-week healing period, the animals were sacrificed. The combination of collagen membranes with rhBMP-2 and BCP yielded significantly higher bone formation rates compared to the other groups (control group and groups 1–5 < groups 6 and 7; p < 0.05). A 2-week healing period yielded significantly lower bone formation than that at 4 and 8 weeks (2 < 4 = 8 weeks; p < 0.05). This study proposes a novel GBR concept in which rhBMP-2 is applied to collagen membranes outside instead of inside the grafted area, thereby inducing quantitatively and qualitatively enhanced bone regeneration in critical bone defects.

Utilizing a social learning perspective, this study investigated the associations between vicarious and direct racism and generalized trust among Asian communities in New Zealand during COVID-19, highlighting the comparability of their effects. Data from a cross-sectional online survey conducted in 2021 (N = 1377), were utilized to estimate the prevalence of vicarious and direct racism experiences and the distribution of since-COVID generalized trust. Linear regression was used to assess the association between experiences of racism and shifts in generalized trust. Findings indicate that almost 40 % of participants experienced racism, with vicarious experiences of physical violence and unfair treatment being more prevalent, while direct experiences of microaggressions and verbal/written abuse were more common. Female, younger, Chinese, and South East Asian participants, those for whom English is a first language, and students reported disproportionate reductions in generalized trust. Negative associations were identified between vicarious and direct racism experiences and changes in generalized trust. Crucially, our analysis reveals that vicarious microaggression experiences have a greater negative association with generalized trust than direct experiences, challenging prevailing perceptions of their significance. Emphasizing a comprehensive approach to eliminating all forms of racism, the findings support the need for critical scrutiny of media reporting of racism and its influence on trust.

INTRODUCTION: Anti-Asian racism was a feature of the social response to the Covid-19 pandemic, and its impact on the well-being of Asian communities warrants closer examination. The current study aimed to gauge whether the sense of belonging mitigated the adverse effects of racism on life satisfaction for self-identified Asian New Zealanders. METHODS: This analysis included 1341 responses to a cross-sectional online survey conducted in 2021. Descriptive analyses outline how components of a sense of belonging were distributed among participants and those who experienced racism during the Covid-19 pandemic. We used linear regression to examine the role of a sense of belonging as a potential pathway variable in the association between experiencing racism and life satisfaction. FINDINGS: In this survey, four out of 10 participants reported experiencing racism in the first 18 months of the pandemic. Participants' life satisfaction decreased slightly since January 2020 (p<0.001). Experiencing racism was associated with decreased life satisfaction. All the components of sense of belonging reduced the magnitude of this negative association between racism experience and life satisfaction, in particular, expressing one's own ethnic identity and belonging in Aotearoa. CONCLUSIONS: Given that anti-Asian racism is currently a feature of life and a significant stressor during the pandemic, this study provides empirical evidence of the protective role of a sense of belonging against anti-Asian racism. This study focused on Asian members in Aotearoa New Zealand, but its practical implications have the potential to support other minoritised ethnic communities who also experience racism during the pandemic and beyond.

Plastic pollution has become a global concern, demanding urgent attention and concerted efforts to mitigate its environmental impacts. Biodegradable plastics have emerged as a potential solution, offering the prospect of reduced harm through degradation over time. However, the lower mechanical strength and slower degradation process of biodegradable plastics have hindered their widespread adoption. In this study, we investigate the incorporation of New Zealand (NZ) jade (pounamu) particles into poly(lactic acid) (PLA) to enhance the performance of the resulting composite. We aim to improve mechanical strength, flame retardation, and degradability. The material properties and compatibility with 3D printing technology were examined through a series of characterization techniques, including X-ray diffraction, dispersive X-ray fluorescence spectrometry, scanning electron microscopy, energy-dispersive X-ray spectroscopy, thermogravimetric analysis, 3D printing, compression molding, pycnometry, rheometry, tensile tests, three-point bending, and flammability testing. Our findings demonstrate that the addition of NZ jade particles significantly affects the density, thermal stability, and mechanical properties of the composites. Compounding NZ jade shows two different changes in thermal stability. It reduces flammability suggesting potential flame-retardant properties, and it accelerates the thermal degradation process as observed from the thermogravimetric analysis and the inferred decrease in molecular weight through rheometry. Thus, the presence of jade particles can also have the potential to enhance biodegradation, although further research is needed to assess its impact. The mechanical properties differ between compression-molded and 3D-printed samples, with compression-molded composites exhibiting higher strength and stiffness. Increasing jade content in composites further enhances their mechanical performance. Th results of this study contribute to the development of sustainable solutions for plastic pollution, paving the way for innovative applications and a cleaner environment. [ABSTRACT FROM AUTHOR]

This research paper reports the findings from an international survey of fieldwork practitioners on their use of technology to enhance fieldwork teaching and learning. It was found that there was high information technology usage before and after time in the field, but some were also using portable devices such as smartphones and global positioning system whilst out in the field. The main pedagogic reasons cited for the use of technology were the need for efficient data processing and to develop students' technological skills. The influencing factors and barriers to the use of technology as well as the importance of emerging technologies are discussed.

In Pacific Rim countries parents of children with developmental disabilities have organized peer support organizations. One form of peer support is Parent to Parent based on one to one connections between two parents. The movements to create and sustain peer support in the U.S., New Zealand, China, and Korea are described. Qualitative evidence from interviews in the US indicates several reasons why Parent to Parent is effective for some of the people who obtain social provisions from the organizations. Peer support helps parents resist social stigma, gain hope, and obtain persuasive guidance. They are able to exchange situated knowledge from their lived experiences with children with disabilities (Brown, Collins & Duguid, 1989). This kind of information may not be available through other sources.

Background: The 'weekend effect' is the term given to the observed discrepancy regarding patient care and outcomes on weekends compared to weekdays. This study aimed to determine whether the weekend effect exists within Aotearoa New Zealand (AoNZ) for patients undergoing emergency laparotomy (EL), given recent advances in management of EL patients. Methods: A cohort study was conducted across five hospitals, comparing the outcomes of weekend and weekday acute EL. A propensity‐score matched analysis was used to remove potential confounding patient characteristics. Results: Of the 487 patients included, 132 received EL over the weekend. There was no statistically significant difference between patients undergoing EL over the weekend compared to weekdays. Mortality rates were comparable between the weekday and weekend cohorts (P = 0.464). Conclusions: These results suggest that modern perioperative care practice in New Zealand obviates the 'weekend' effect. [ABSTRACT FROM AUTHOR]

This study investigates family language policy (FLP) in three dual heritage and interlingual families in New Zealand. It focuses on the language use of three Korean migrant mothers and their attitudes towards their children's multilingualism and heritage languages (HLs). Each family's FLP took a "one person, one language" approach, with the mothers consistently using Korean but occasionally switching to English. All three mothers in this case study showed positive attitudes towards their children maintaining their HLs, and used various strategies to encourage their children's exposure to the HLs. However, each of the mothers conceptualized the positions of the children's HLs somewhat differently, which influenced language socialization at home. Moreover, despite their strong commitment to bilingual or multilingual parenting, the mothers had low expectations for their children's HL proficiency, reflecting the minority status of HLs in the wider society.

The importance of wildlife health has been critically emphasized by the current global pandemic. Pharmacists play a valuable role in the health care of companion animals and livestock; however, their involvement in exotic animal health is largely unexplored. This project consulted with zoo vets in New Zealand and investigated their practices around prescribing and dispensing of medicines to explore the opportunities for the involvement of pharmacists. A mixed methods approach was used where data were initially collected through an online survey distributed to 26 veterinarians and animal keepers working in zoos, wildlife parks, and sanctuaries. An optional semistructured interview followed the survey. The facilities surveyed housed New Zealand native animal species and 85% also housed exotic animals. Veterinarians dispensed 75% of medicines at their animal facility, whereas the remaining 25% were dispensed by veterinary nurses. On average, 5-10 medications were dispensed at each animal facility per day. Common medicines dispensed were antibiotics, pain relievers, and antifungals. Most respondents felt that they could benefit from working alongside pharmacists in veterinary care. Compounding, access to medicines and identification of tailored formulations were identified as areas where collaboration would be valued. Limitations in the knowledge of pharmacists in animal medicine were distinguished as an area enhancement to assist in collaborative relationships. There are opportunities for the skills of pharmacists to be incorporated into the care of animals in zoos and wildlife parks in New Zealand. Strengthening the pharmacist-veterinarian relationship can enhance the health outcomes of animals in animal facilities through this interprofessional interaction.

Fungi in the class Leotiomycetes are ecologically diverse, including mycorrhizas, endophytes of roots and leaves, plant pathogens, aquatic and aero-aquatic hyphomycetes, mammalian pathogens, and saprobes. Hymenotorrendiella species are often assumed to be saprobic, their fruiting bodies developing on fallen leaves and dead wood but, in many cases, these putative saprobes are found on only a single host. For the leaf-inhabiting species this host specialisation has been shown to be driven by an endophytic phase to the life cycle, the initial infection of the host being on living leaves. Host specialisation has resulted in high levels of species diversity but within Hymenotorrendiella most of these species remain unnamed. In this paper four species of Hymenotorrendiella are accepted from Eucalyptus in Australia — the leaf-inhabiting H. communis, as well as three wood-inhabiting species, H. clelandii, and two species described here as new, H. spooneri and H. brevis. The leaf-inhabiting H. communis has an endophytic phase to its life cycle, fruiting on dead leaves but with infection initiated while the leaves are still alive and appears to have been moved around the world along with its Eucalyptus host. The biology of the wood-inhabiting species is unknown although H. clelandii occurs also in New Zealand on introduced Eucalyptus. Also described here are two other wood-inhabiting species from New Zealand that are closely related to H. clelandii – H. coriariae from Coriaria arborea, and H. pruinosa from Leptospermum and Kunzea. H. spooneri as accepted here appears to comprise a phylogenetically diverse complex of several closely related sister populations. These populations differ somewhat morphologically, but each is represented by only one specimen, making it impossible at present to assess the possible taxonomic significance of those morphological differences.

This study was conducted to investigate the combination of nisin Z and NaCl as a natural food preservative to improve the quality of fish products under refrigerated temperatures. Treatments against Listeria monocytogenes and Staphylococcus aureus included 1000 IU nisin Z (NZ) in 3% (NZ3), 5% (NZ5), or 7% NaCl solution (NZ7). Both NZ5 and NZ7 showed significantly higher antimicrobial activities, and minced Nile tilapia (Oreochromisniloticus) inoculated with L. monocytogenes or S. aureus showed a reduced microbial load compared to the positive control groups. Therefore, the combination of nisin Z and NaCl exhibited potent antibacterial activities, highlighting its usability as a natural alternative to synthetic preservatives. [ABSTRACT FROM AUTHOR]

Duchenne muscular dystrophy (DMD) is a life-shortening genetic condition involving progressive muscular wasting for which there is no hope of recovery at present. The lives of people with DMD, cherished by their families, are systematically marginalised and undervalued by healthcare bureaucracies while enrolment in clinical trials of new treatments offers possibilities of longer-term biomedical solutions. How is hope preserved under such circumstances and what activities can promote a full and meaningful life for those with DMD? Ethnographic research within the DMD community in Aotearoa New Zealand provided a basis for addressing these questions and for understanding different concepts of hope and social suffering, the value of life in DMD and disability studies, and how these are shaped by regimes of governmentality.

Purpose: To compare the bone responses of chemically modified implants using the plasma immersion ion implantation and deposition method with those of blasted implants. Materials and Methods: The titanium implants were blasted with resorbable blasting media (RBM) and designated as controls. The ion-implanted implants were divided into two test groups, namely, calcium (Ca) and magnesium (Mg) implants. Six implants (two implants per group) were placed into the proximal tibias of 11 New Zealand white rabbits. Fluorochrome labeling was administered at 2 and 4 weeks after surgery. Resonance frequency analysis (RFA) was conducted immediately after surgery and at 6 weeks of healing. The removal torque was measured in half of the tibiae. The implants in another tibia were subjected to fluorescence analysis and histologic and histomorphometric evaluations. Results: The fluorescence analysis suggested that osteoconductivity was improved in the early osseointegration stages in the Ca and Mg implants. In the cortical region, the bone-to-implant contact in the Mg implants and the bone area % in the Ca and Mg implants were higher than those in the RBM implants (P < .05). All groups demonstrated similar biomechanical strengths with respect to the RFA and the removal torque measurements. Conclusion: The osseointegration speed and the bone contact were positively affected by the Ca and Mg ion implantation, especially in the Mg implants, because of the synergistic effect. However, no remarkable differences were found in biomechanical strength in the later osseointegration stages. [ABSTRACT FROM AUTHOR]

A study using live rabbits with analysis of stained excised corneas showed dispersive OVD provides significantly more corneal endothelial cell protection from simulated lenticular debris than cohesive OVD during phacoemulsification. Purpose: To compare the protection of the corneal endothelium provided by a cohesive and a dispersive ophthalmic viscosurgical device (OVD) against damage from torsional ultrasound and simulated lenticular debris during phacoemulsification. Setting: University setting, Salt Lake City, Utah. Design: Experimental study. Methods: 15 New Zealand rabbits were included. After incision, each eye received cohesive or dispersive OVD (ProVisc or Viscoat). 10 1.0 mm beads were injected to simulate lenticular debris. The Intrepid Balanced tip (Centurion Ozil handpiece) was inserted into the anterior chamber, and 60% torsional ultrasound with 50 mL/min flow, 70 mm Hg intraocular pressure, and 600 mm Hg vacuum was applied (20 seconds). Cumulative dissipated energy (CDE) was noted. After euthanasia and enucleation, corneas were removed, stained with trypan blue/alizarin red, and photographed (5 ×400 magnification photos and 1 overview photograph from each cornea). ImageJ was used to evaluate cell damage and loss. Results: CDE was 4.70 ± 0.26 and 4.64 ± 0.10 in the cohesive and dispersive OVD groups, respectively (P =.8647). The analysis of the ×400 photographs showed that the percentage of intact cells was statistically higher in the dispersive OVD group (P =.0002), whereas the percentages of damaged and lost cells were statistically higher in the cohesive OVD group (P =.0002 and.0059, respectively). Overview photographs revealed the presence of residual OVD on the endothelium, especially in the dispersive group. Conclusions: In this experimental study using a rabbit model, the corneal endothelium protection provided by the dispersive OVD was superior to that provided by the cohesive OVD.

A study using live rabbits, with subsequent analysis of excised corneas stained with trypan blue/alizarin red, showing simulated swirling lenticular debris may contribute significantly to corneal endothelium damage during phacoemulsification. Purpose: To evaluate mechanical damage of simulated lenticular debris on corneal endothelial cells during phacoemulsification. Setting: University setting, Salt Lake City, Utah. Design: Experimental study. Methods: 12 New Zealand rabbits underwent bilateral surgery. After incision, 10 1.0 mm beads were injected into the anterior chamber of test eyes to simulate lenticular debris. A balanced salt solution was injected into the contralateral eyes with the same injector. The Intrepid Balanced Tip of the Centurion Ozil handpiece was inserted into the anterior chamber, and 60% torsional ultrasound was applied for 20 seconds with 50 mL/min flow, 70 mm Hg intraocular pressure, and 600 mm Hg vacuum. Cumulative dissipated energy (CDE) was noted. After euthanasia and enucleation, the corneas were removed, stained with trypan blue/alizarin red, and photographed in a standardized manner (×400 photographs from 5 specific areas and 1 overview photograph from each corneal button). The ImageJ program was used to evaluate cell damage and loss in the photographs. Results: CDE was 4.64 ± 0.19 for test eyes with beads and 4.66 ± 0.17 for control eyes without beads (P =.58). The percentage of intact cells was statistically higher in the control group (P =.0005), whereas the percentages of damaged and lost cells were statistically higher in the test group (P =.0010 and.0005, respectively). This was observed in the analysis of the ×400 photographs and overview photographs. Conclusions: This study suggests that lenticular debris swirling around the anterior chamber may cause significant damage to the corneal endothelium, providing further insight on mechanisms of damage during phacoemulsification.

Some heritable endosymbionts can affect host mtDNA evolution in various ways. Amphipods host diverse endosymbionts, but whether their mtDNA has been influenced by these endosymbionts has yet to be considered. Here, we investigated the role of endosymbionts (microsporidians and Rickettsia) in explaining highly divergent COI sequences in Paracalliope fluviatilis species complex, the most common freshwater amphipods in New Zealand. We first contrasted phylogeographic patterns using COI, ITS, and 28S sequences. While molecular species delimitation methods based on 28S sequences supported 3–4 potential species (N, C, SA, and SB) among freshwater lineages, COI sequences supported 17–27 putative species reflecting high inter‐population divergence. The deep divergence between NC and S lineages (~20%; 28S) and the substitution saturation on the 3rd codon position of COI detected even within one lineage (SA) indicate a very high level of morphological stasis. Interestingly, individuals infected and uninfected by Rickettsia comprised divergent COI lineages in one of four populations tested, suggesting a potential influence of endosymbionts in mtDNA patterns. We propose several plausible explanations for divergent COI lineages, although they would need further testing with multiple lines of evidence. Lastly, due to common morphological stasis and the presence of endosymbionts, phylogeographic patterns of amphipods based on mtDNA should be interpreted with caution. [ABSTRACT FROM AUTHOR]

Background: Recent studies have reported improved diastolic function in patients administered sodium-glucose cotransporter 2 inhibitors (SGLT2i). We aimed to investigate the effect of dapagliflozin on left ventricular (LV) diastolic function in a diabetic animal model and to determine the molecular and cellular mechanisms underlying its function.Methods: A total of 30 male New Zealand white rabbits were randomized into control, diabetes, or diabetes+dapagliflozin groups (n = 10/per each group). Diabetes was induced by intravenous alloxan. Cardiac function was evaluated using echocardiography. Myocardial samples were obtained for histologic and molecular evaluation. For cellular evaluation, fibrosis-induced cardiomyoblast (H9C2) cells were obtained, and transfection was performed for mechanism analysis (serum and glucocorticoid-regulated kinase 1 (SGK1) signaling analysis).Results: The diabetes+dapagliflozin group showed attenuation of diastolic dysfunction compared with the diabetes group. Dapagliflozin inhibited myocardial fibrosis via inhibition of SGK1 and epithelial sodium channel (ENaC) protein, which was observed both in myocardial tissue and H9C2 cells. In addition, dapagliflozin showed an anti-inflammatory effect and ameliorated mitochondrial disruption. Inhibition of SGK1 expression by siRNA decreased and ENaC and Na+/H+ exchanger isoform 1 (NHE1) expression was confirmed as significantly reduced as siSGK1 in the diabetes+dapagliflozin group.Conclusions: Dapagliflozin attenuated left ventricular diastolic dysfunction and cardiac fibrosis via regulation of SGK1 signaling. Dapagliflozin also reduced macrophages and inflammatory proteins and ameliorated mitochondrial disruption. [ABSTRACT FROM AUTHOR]

The purpose of this article is to present the research findings from a qualitative study on a type of second migration experienced by Korean-New Zealand immigrants in Australia. Data were collected from 16 in-depth interviews with those people who initially moved from South Korea to New Zealand, and then migrated to Australia. The study findings show that the participants were likely to experience 'soft-landing' relocation, ethnically internal belonging and identity flexibility. A critical reflection on this second-migration phenomenon is presented in order to help social work professionals broaden their perspectives on today's fluid migration and its implications for practice.
