BACKGROUND: Osteoporosis (OP) and osteomalacia (OM) are metabolic bone diseases characterized by mineral and matrix density changes. Quantitative bone matrix density differentiates OM from OP. MRI is a noninvasive and nonionizing imaging technique that can measure bone matrix density quantitatively in ex vivo and in vivo. PURPOSE: To demonstrate water + fat suppressed 1 H MRI to compute bone matrix density in ex vivo rat femurs in the preclinical model...

INTRODUCTION: Emergency medicine (EM) has historically been among the most competitive specialties in the United States. However, in 2022 and 2023, 219 of 2921 and 554 of 3010 respective National Resident Matching Program positions were initially unfilled. Medical students' selection of a medical specialty is a complex process. To better understand recent trends in the EM residency match, this qualitative study explored through one-on-one interviews the rationale of senior medical students who seriously considered EM but ultimately pursued another specialty...

BACKGROUND: There is a strong association between perfectionism and eating disorders. In a cognitive-behavioural model of compulsive exercise it has been suggested there are reciprocal associations between perfectionism, eating disorder pathology, and compulsive exercise. No study has examined if there is an indirect association between perfectionism and compulsive exercise through eating disorder pathology, which would inform a preliminary understanding of the cognitive-behavioural model of compulsive exercise...

PROBLEM: The significance and complexities of a psychiatric diagnosis have been well-documented in existing literature. Despite the reliability and accuracy of such diagnoses, the impact and use of diagnostic labelling on young people remains unclear. METHODS: A systematic review was conducted using six databases, identifying 13 studies that explored psychiatric diagnosis experiences in professionals, caregivers, and young people. FINDINGS: This review focuses on three main themes related to psychiatric diagnosis in young people...

We report the electrochemiluminescence (ECL) of a 3d6 Cr(0) complex ([Cr(LMes)3]; λem = 735 nm) with comparable photophysical properties to those of ECL-active complexes of 4d6 or 5d6 precious metal ions. The electrochemical potentials of [Cr(LMes)3] are more negative than those of [Ir(ppy)3] and render the [Cr(LMes)3]* excited state inaccessible through conventional co-reactant ECL with tri-n-propylamine or oxalate. ECL can be obtained, however, through the annihilation route in which potentials sufficient to oxidise and reduce the luminophore are alternately applied...

This is a protocol for a Campbell Review following JBI scoping review methodology. The objectives are to answer the following questions: What has been reported in the literature about collaborative learner-educator design, implementation, or evaluation of learner assessment in health professional education? (1) Where is learner-educator co-creation of assessment occurring? (i.e., which disciplines, course types, level of learner, year of study). (2) What course assessment decisions are influenced or being made together? (i...

BACKGROUND: Cotton accounts for 80% of the global natural fibre production. Its leaf hairiness affects insect resistance, fibre yield, and economic value. However, this phenotype is still qualitatively assessed by visually attributing a Genotype Hairiness Score (GHS) to a leaf/plant, or by using the HairNet deep-learning model which also outputs a GHS. Here, we introduce HairNet2, a quantitative deep-learning model which detects leaf hairs (trichomes) from images and outputs a segmentation mask and a Leaf Trichome Score (LTS)...

In an age of species declines, delineating and discovering biodiversity is critical for both taxonomic accuracy and conservation. In recent years, there has been a movement away from using exclusively morphological characters to delineate and describe taxa and an increase in the use of molecular markers to describe diversity or through integrative taxonomy, which employs traditional morphological characters, as well as genetic or other data. Tiger beetles are charismatic, of conservation concern, and much work has been done on the morphological delineation of species and subspecies, but few of these taxa have been tested with genetic analyses...

The strength of reproductive isolation (RI) between two or more lineages during the process of speciation can vary by the ecological conditions. However, most speciation research has been limited to studying how ecologically dependent RI varies among a handful of broadly categorized environments. Very few studies consider the variability of RI and its effects on speciation at finer scales-that is, within each environment due to spatial or temporal environmental heterogeneity. Such variation in RI across time and/or space may inhibit speciation through leaky reproductive barriers or promote speciation by facilitating reinforcement...

PURPOSE: To explore women's lived experiences of intimacy, sexuality and sexual functioning in the context of cauda equina syndrome (CES). METHODS: Ten women completed an in-depth semi-structured interview exploring the psychosocial impact of CES on their sexuality and data were analyzed using Interpretative Phenomenological Analysis (IPA). RESULTS: One superordinate theme was generated: "Sexuality forever altered, it's changed completely," reflecting the enduring impact of CES on women's sexuality...

BACKGROUND: Regular participation in physical activity (PA) benefits children's health and well-being and protects against the development of unhealthy body weight. A key factor in children's PA participation is their motor competence (MC). The comprehensive school physical activity program (CSPAP) framework offers a way to classify existing PA interventions that have included children's MC development and understand the potential avenues for supporting children's MC. However, there have been no systematic reviews or meta-analyses of PA interventions and their effects on the MC of elementary school children (aged 5-12 years) from a CSPAP perspective...

Goal: Dynamically monitoring serotonin in real-time within target brain regions would significantly improve the diagnostic and therapeutic approaches to a variety of neurological and psychiatric disorders. Current systems for measuring serotonin lack immediacy and portability and are bulky and expensive. Methods: We present a new miniaturised device, named SmartFSCV, designed to monitor dynamic changes of serotonin using fast-scan cyclic voltammetry (FSCV). This device outputs a precision voltage potential between -3 to +3 V, and measures current between -1...

This article draws on the concept of cultural humility, to describe and analyze a decolonizing approach to co-designing a primary prevention basketball program for young African-Australian people in Melbourne, Australia. We explore the potential for genuine collaboration and power-sharing with a culturally diverse community through collaboratively developing the co-design process and resultant program design. This article highlights the central role of UBUNTU in the co-design process, prioritizing African ways of knowing, being, and doing within a Westernized social work and design context...

PURPOSE: Although diabetes is highly prevalent in patients with MacTel, progression to severe non-proliferative (NPDR) and proliferative diabetic retinopathy (PDR) is rarely reported. We report multimodal imaging features of sight-threatening diabetic retinopathy (STDR) in eyes with macular telangiectasia type 2 (MacTel). METHODS: Retrospective case series of seven participants of the MacTel Study at the Moorfields Eye Hospital NHS Foundation Trust study site and one patient from the Institute of Retina and Vitreous of Londrina, Brazil...

The rapid development of organic-inorganic hybrid perovskite solar cells has resulted in laboratory-scale devices having power conversion efficiencies that are competitive with commercialised technologies. However, hybrid perovskite solar cells are yet to make an impact beyond the research community, with translation to large-area devices fabricated by industry-relevant manufacturing methods remaining a critical challenge. Here we report the first demonstration of hybrid perovskite solar cell modules, comprising serially-interconnected cells, produced entirely using industrial roll-to-roll printing tools under ambient room conditions...

IMPORTANCE: A substantial number of opioid analgesics dispensed into communities will go unused and be susceptible to diversion for misuse. Convenient, efficient, and environmentally safe mechanisms for disposal are needed to prevent the diversion of unused opioid analgesics. OBJECTIVE: This initiative piloted the feasibility of distributing drug deactivation pouches in a community setting and examined community members' acceptance, intention to use drug deactivation pouches, and their current disposal practices of unused opioid analgesics...

The targeted compounds were prepared using both (9H-fluoren-9-ylidene)hydrazine (1) and 10H-phenothiazine (2) as starting materials. The treatment of 1 or 2 with different isocyanates afforded the title compounds 7a-d, 8a, and 8b in excellent yield. All compounds were characterized and ascertained by infrared, nuclear magnetic resonance, and elemental analyses as well as single-crystal X-ray diffraction. The antimicrobial efficiency of all was tested in vitro, and a noticeable inhibition activity against Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Candida albicans was obtained by compounds 7a, 7b, 8a, and 8b...
