Widespread variation in molecular interactions and regulatory properties among transcription factor isoforms.

Most human Transcription factors (TFs) genes encode multiple protein isoforms differing in DNA binding domains, effector domains, or other protein regions. The global extent to which this results in functional differences between isoforms remains unknown. Here, we systematically compared 693 isoforms of 246 TF genes, assessing DNA binding, protein binding, transcriptional activation, subcellular localization, and condensate formation. Relative to reference isoforms, two-thirds of alternative TF isoforms exhibit differences in one or more molecular activities, which often could not be predicted from sequence. We observed two primary categories of alternative TF isoforms: "rewirers" and "negative regulators", both of which were associated with differentiation and cancer. Our results support a model wherein the relative expression levels of, and interactions involving, TF isoforms add an understudied layer of complexity to gene regulatory networks, demonstrating the importance of isoform-aware characterization of TF functions and providing a rich resource for further studies.

Gender Moderates the Relationship Between Avatar Customization and Enjoyment in Popular Video Games.

Using online survey methods (n = 153), this study investigates whether exposure to different levels of customization in games will increase the experiences of enjoyment, both directly and indirectly, through the experience of avatar embodiment, as well as whether these relationships are influenced by gender identity. Results indicate a positive relationship between level of exposure to customization and enjoyment for women-identified participants. These outcomes may provide insight into gendered preference in gaming, potentially providing an avenue by which to make games more inclusive to women gamers.

Use of Hyaluronic Acid Filler in Patients with Secondary Cleft Lip Deformity.

METHODS: Retrospective case note review was undertaken of all patients treated in the clinic over a two-year period. RESULTS: 20 patients underwent HA filler injections to the upper lip 26 times. Most were female (F:M = 3:1) and patients were aged 18-58 years. Most patients had a unilateral cleft lip +/- palate (n = 13, 65%). The most common indication was to address upper lip volume (n = 13, 65%). Other indications included vermillion notch (n = 5, 25%), cupid bow peak height asymmetry (n = 4, 20%), scar asymmetry (n = 1, 5%) and nasal sill flattening (n = 1, 5%). Small volumes of filler were used with an average of 0.34 ml (range 0.05-1.2 ml). There were no complications and one patient reported pruritis post procedure. CONCLUSIONS: HA filler is a safe and reliable treatment for certain aspects of asymmetry following cleft lip repair. It can be used to address volume deficiency and asymmetry, cupid bow peak height discrepancies and a vermillion notch for patients who do not want surgery. Injection of HA to the lips can be performed easily, with appropriate training, in the outpatient setting.

What Do Social Media Influencers Say About Birth Control? A Content Analysis of YouTube Vlogs About Birth Control.

Youth get their sexual health information from social media, often from social media influencers (SMIs) or microcelebrities with large followings. Previous research suggests that SMIs have powerful persuasive effects on attitudes and behaviors. Thus, it is important to examine the ways in which sexual health information, such as birth control, is conveyed by SMIs. Using framing theory as a theoretical framework, this study examines characteristics of SMIs and their shared experiences pertaining to birth control. A content analysis of YouTube vlogs (n = 50) posted from December 2019-2021 was conducted on SMIs who talk about their experiences using hormonal and non-hormonal birth control. SMI status was determined based on the number of people subscribed to the YouTube channels. Results suggest that SMI YouTube videos are primarily about the discontinuation of hormonal birth control and may provide inaccurate sexual health information. Reasons for discontinuation of hormonal birth control provided by the SMIs are discussed. Future research should explore the effects of influencer sexual health messaging on beliefs, attitudes, and behaviors.

Philtral Height Discrepancy in Patients with Complete and Incomplete Cleft Lips + /-Palate - Results from a Single Nation Consecutive Cohort.

INTRODUCTION: The aim of unilateral cleft lip repair is to restore form and function, including symmetrisation of cleft and non-cleft philtral height. Expectation of best outcome is achieved in situations with minimal asymmetry and is assumed occurs most often in incomplete cleft lip only patients. We sought to investigate philtral height discrepancy (PHD) in children with unilateral cleft lip + /-palate from a single nation cohort. METHODS: Review of prospectively collected PHD measurements taken at time of surgery for all children undergoing unilateral cleft lip repair in Scotland born Jan 2017-December 2020. Data was collected using Microsoft Excel and analysed using embedded statistical software. RESULTS: 102 consecutive patients with unilateral lip involvement were identified from the national database. 94 had prospectively documented PHD (92.2%). The majority of patients had an isolated cleft lip (51.1%). Incomplete clefts presented more frequently (52.1%) than complete clefts (47.9%). Mean PHD for the whole cohort was 3.91mm (standard deviation 1.01mm, range 1-6mm). The difference in mean PHD (in-complete versus complete) was 1.1mm (3.4 vs. 4.5, p < 0.001). For lip only versus lip and palate the difference in mean PHD was 1.0mm (3.4 vs. 4.4, p < 0.001). CONCLUSIONS: This single country consecutive cohort review of PHD in children undergoing unilateral cleft lip repair statistically supports the anecdote that patients with an incomplete cleft lip and isolated cleft lip have lesser asymmetry at presentation. This study presents a consecutive cohort with a greater range of PHD than has previously been reported in the literature.

Spatial and temporal analysis of the risks posed by metal contamination in coastal and marine sediments of Bahrain.

Nine metals including Al, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were analysed from sediment samples collected from 29 stations since 2007 from Bahraini waters. Within this study, it was investigated whether concentrations of these determinants are at concentrations above internationally established Assessment Criteria (AC). The majority of sites were considered not to pose a toxicological risk in terms of metal contamination. Where breaches occurred, they were mainly from historic samples related to Cr, Cu and Ni contamination. A trend assessment revealed that out of 59 significant trends, 36 were downwards and 23 upwards, indicating that some determinants like Al, Zn and Ni are improving strongly across some sites, whilst areas associated with industrial activity still see some increasing trends for Al, Cd, Pb and Zn.

A seafood risk tool for assessing and mitigating chemical and pathogen hazards in the aquaculture supply chain.

Intricate links between aquatic animals and their environment expose them to chemical and pathogenic hazards, which can disrupt seafood supply. Here we outline a risk schema for assessing potential impacts of chemical and microbial hazards on discrete subsectors of aquaculture-and control measures that may protect supply. As national governments develop strategies to achieve volumetric expansion in seafood production from aquaculture to meet increasing demand, we propose an urgent need for simultaneous focus on controlling those hazards that limit its production, harvesting, processing, trade and safe consumption. Policies aligning national and international water quality control measures for minimizing interaction with, and impact of, hazards on seafood supply will be critical as consumers increasingly rely on the aquaculture sector to supply safe, nutritious and healthy diets.

Aquatic contaminants in Solomon Islands and Vanuatu: Evidence from passive samplers and Microtox toxicity assessment.

Water Quality issues in many Pacific countries are rising, with the increase in coastal populations and associated urban runoff but management requires contamination issues in the aquatic environment to be identified and prioritised. In Vanuatu and Solomon Islands there are few laboratories and resources to assess for the presence or impact of complex chemical contaminants. The extent and impact of chemical contamination of the marine and coastal environment is poorly described. Passive chemical samplers were used to measure a range of aquatic pollutants around the capital cities, Honiara (Solomon Islands) and Port Vila (Vanuatu). We detected a range of chemicals indicative of agricultural and industrial contamination and a few sites had concerning concentrations of specific hydrocarbons and pesticides. The rapid ecotoxicology test, Microtox, indicated toxic impacts in rivers, coastal sites and urban drains This work provides new data on chemical contamination and possible impacts of that contamination for both countries. The techniques could be applied widely across the region to generate critical data for environmental management, guide monitoring efforts and measure the impact of policy or land-use changes.

Kuwait's marine biodiversity: Qualitative assessment of indicator habitats and species.

The tropical waters of the Northern Arabian Gulf have a long history of maritime resource richness. High levels of biodiversity result from the complex matrix of coastal habitats, coral reefs and sea grass beds that characterise the region. Insight into the ongoing health of such habitats and the broader Kuwait maritime environment can be gauged by the status of indicator species found within these habitats. Here we review information on the occurrence, distribution and threats to key marine habitats and associated indicator species to provide an updated assessment of the state of the Kuwait's marine biodiversity. Critical evaluation of historic data highlights knowledge gaps needed inform the focus of future monitoring and conservation efforts. This assessment is designed to evaluate performance against environmental policy commitments, while providing a solid foundation for the design of comprehensive marine ecosystem management strategies.

Seagrass habitat in Tarawa Lagoon, Kiribati: Service benefits and links to national priority issues.

This paper presents a review around seagrass habitat in Tarawa Lagoon, Kiribati and explores the links between seagrass occurrence and the national priority issues of climate change, urban development, human health, nearshore fisheries, threatened species, ocean policy, research capacity and awareness. The contribution of healthy seagrass habitats to many aspects of these national issues is often overlooked and there is need to establish the knowledge gaps and priority actions that can enable mitigation of issues that impact on valuable seagrass resources and their management. Research data on seagrass habitats in Kiribati, and the wider Pacific Island region, is limited and this hinders informed decisions at local, national and regional levels. We present a comprehensive review on seagrass within a national context to aid prioritisation and uptake of information for resource owners, and wider stakeholders, in Kiribati while acknowledging local expertise. The paper highlights data and knowledge gaps that if addressed, will provide information useful to Kiribati nationals, communities and government stakeholders. Recommendations for actions that fill these gaps and build understanding of seagrass resources in Kiribati are provided.

Sustainable aquaculture through the One Health lens.

Aquaculture is predicted to supply the majority of aquatic dietary protein by 2050. For aquaculture to deliver significantly enhanced volumes of food in a sustainable manner, appropriate account needs to be taken of its impacts on environmental integrity, farmed organism health and welfare, and human health. Here, we explore increased aquaculture production through the One Health lens and define a set of success metrics - underpinned by evidence, policy and legislation - that must be embedded into aquaculture sustainability. We provide a framework for defining, monitoring and averting potential negative impacts of enhanced production - and consider interactions with land-based food systems. These metrics will inform national and international science and policy strategies to support improved aquatic food system design.

Unilateral soft palate palsy secondary to blunt neck trauma: a case report.

Unilateral soft palate paralysis is rare. No cases of unilateral soft palate paralysis with associated velopharyngeal insufficiency (VPI) secondary to minor blunt neck trauma have been reported to date. This case details the presentation of a man with isolated unilateral soft palate paralysis and associated velopharyngeal insufficiency following a collision with an opponent when playing soccer.

Preequilibrium Asymmetries in the

The physical properties of neutrons emitted from neutron-induced fission are fundamental to our understanding of nuclear fission. However, while state-of-the-art fission models still incorporate isotropic fission neutron spectra, it is believed that the preequilibrium prefission component of these spectra is strongly anisotropic. The lack of experimental guidance on this feature has not motivated incorporation of anisotropic neutron spectra in fission models, though any significant anisotropy would impact descriptions of a fissioning system. In the present work, an excess of counts at high energies in the fission neutron spectrum of ^{239}Pu is clearly observed and identified as an excess of the preequilibrium prefission distribution above the postfission neutron spectrum. This excess is separated from the underlying postfission neutron spectrum, and its angular distribution is determined as a function in incident neutron energy and outgoing neutron detection angle. Comparison with neutron scattering models provides the first experimental evidence that the preequilibrium angular distribution is uncorrelated with the fission axis. The results presented here also impact the interpretation of several influential prompt fission neutron spectrum measurements.

17ß-estradiol vaginal tablet versus conjugated equine estrogen vaginal cream to relieve menopausal atrophic vaginitis.

OBJECTIVES: The efficacy and safety of 25-µg 17ß-estradiol vaginal tablets (Vagifem) were assessed and compared with 1.25-mg conjugated equine estrogen vaginal cream (Premarin Vaginal Cream) for the relief of menopausal-derived atrophic vaginitis, resulting from estrogen deficiency. DESIGN: In a multicenter, open-label, randomized, parallel-group study, 159 menopausal women were treated for 24 weeks with either vaginal tablets or vaginal cream. Efficacy was evaluated by relief of vaginal symptoms and concentrations of serum estradiol and follicle-stimulating hormone. Safety was monitored by the incidence of adverse events, evaluation of endometrial biopsies, and clinical laboratory results. Patients also assessed the acceptability of the study medications. RESULTS: Composite scores of vaginal symptoms (dryness, soreness, and irritation) demonstrated that both treatments provided equivalent relief of the symptoms of atrophic vaginitis. At weeks 2, 12, and 24, increases in serum estradiol concentrations and suppression of follicle-stimulating hormone were observed in significantly more patients who were using the vaginal cream than in those who were using the vaginal tablets (p < 0.001). Fewer patients who were using the vaginal tablets experienced endometrial proliferation or hyperplasia compared with patients who were using the vaginal cream. Significantly more patients who were using the vaginal tablets rated their medication favorably than did patients who were using the vaginal cream (p ≤ 0.001). Patients who were receiving the vaginal tablets also had a lower incidence of patient withdrawal (10% versus 32%). CONCLUSIONS: Treatment regimens with 25-µg 17ß-estradiol vaginal tablets and with 1.25-mg conjugated equine estrogen vaginal cream were equivalent in relieving symptoms of atrophic vaginitis. The vaginal tablets demonstrated a localized effect without appreciable systemic estradiol increases or estrogenic side effects. Vaginal tablet therapy resulted in greater patient acceptance and lower withdrawal rates compared with vaginal cream therapy.

Differential effects of high fat diet and diet-induced obesity on skeletal acquisition in female C57BL/6J vs. FVB/NJ Mice.

The effects of obesity on bone metabolism are complex, and may be mediated by consumption of a high fat diet and/or by obesity-induced metabolic dysregulation. To test the hypothesis that both high fat (HF) diet and diet-induced metabolic disease independently decrease skeletal acquisition, we compared effects of HF diet on bone mass and microarchitecture in two mouse strains: diet-induced obesity (DIO)-susceptible C57BL/6J (B6) and DIO-resistant FVB/NJ (FVB). At 3 wks of age we weaned 120 female FVB and B6 mice onto normal (N, 10% Kcal/fat) or HF diet (45% Kcal/fat) and euthanized them at 6, 12 and 20 weeks of age (N = 10/grp). Outcomes included body mass; percent fat and whole-body bone mineral density (WBBMD, g/cm2) via DXA; cortical and trabecular bone architecture at the midshaft and distal femur via µCT; and marrow adiposity via histomorphometry. In FVB HF, body mass, percent body fat, WBBMD and marrow adiposity did not differ vs. N, but trabecular bone mass was lower at 6 wks of age only (p < 0.05), cortical bone geometric properties were lower at 12 wks only, and bone strength was lower at 20 wks of age only in HF vs. N (p < 0.05). In contrast, B6 HF had higher body mass, percent body fat, and leptin vs. N. B6 HF also had higher WBBMD (p < 0.05) at 9 and 12 wks of age but lower distal femur trabecular bone mass at 12 wks of age, and lower body mass-adjusted cortical bone properties at 20 wks of age compared to N (p < 0.05). Marrow adiposity was also markedly higher in B6 HF vs. N. Overall, HF diet negatively affected bone mass in both strains, but was more deleterious to trabecular bone microarchitecture and marrow adiposity in B6 than in FVB mice. These data suggest that in addition to fat consumption itself, the metabolic response to high fat diet independently alters skeletal acquisition in obesity.

Return to work after occupational and non-occupational lower extremity amputation.

BACKGROUND: Factors impacting on return to work (RTW) after lower extremity amputation are important in occupational rehabilitation. AIMS: Our objective was to compare RTW in patients who had traumatic work-related amputation with amputations from other causes. METHODS: A retrospective cohort study was conducted with participants employed at the time of amputation and at least 1 year post-discharge from amputee rehabilitation. The primary outcome measure was RTW. RESULTS: One hundred and forty-seven amputees were included with 69% returning to work. Amputation reason did not impact on RTW (odds ratio [OR] 1.83, P = non-significant). Trans-femoral amputees were less likely to RTW (OR 0.22, P < 0.05). Years since amputation (OR 1.20, P = 0.001) and Reintegration to Normal Living Index (OR 1.05, P < 0.001) were predictive of RTW after adjusting for other covariates. CONCLUSIONS: Amputation aetiology did not impact on RTW. Years since amputation, level of amputation and Return to Normal Living Index were associated with RTW which may be important to consider in RTW prognosis and planning.

Who seeks bariatric surgery? Psychosocial functioning among adolescent candidates, other treatment-seeking adolescents with obesity and healthy controls.

Limited data are available on the characteristics of adolescents with obesity who seek bariatric surgery. Existing data suggest that adolescent surgery candidates have a higher body mass index (BMI) than comparison adolescents with obesity, but the limited findings regarding psychosocial functioning are mixed. This study aimed to compare BMI and psychosocial functioning among adolescent bariatric surgery candidates, outpatient medical-treatment-seeking adolescents with obesity (receiving lifestyle modification), and adolescents in the normal-weight range. All adolescents completed self-report measures of impulsivity, delay discounting, depression, anxiety, stress, eating pathology, family functioning and quality of life, and had their height and weight measured. Adolescent surgical candidates had higher BMIs than both comparison groups. Surgical candidates did not differ from medical-treatment-seeking adolescents with obesity on any measure of psychosocial functioning, but both groups of adolescents with obesity reported greater anxiety and eating pathology and poorer quality of life than normal-weight adolescents. Quality of life no longer differed across groups after controlling for BMI, suggesting that it is highly related to weight status. Adolescents with obesity may experience greater anxiety, eating pathology, and quality of life impairments than their peers in the normal-weight range regardless of whether they are seeking surgery or outpatient medical treatment. Clinical implications and directions for future research are discussed.
