This study examines the impact of gender differentials on sociability indices among undergraduate students in a Nigerian university. The findings of this study focused on individual factors inherent in developing good social skills. An understanding of people’s perceptions of social interaction and the role played by their belief system would help in planning intervention programmes that should be beneficial to society. Generally, dominance is usually difficult to be established in a social group without the group members’ attention. Males have been found to assume dominance in relationships by utilizing verbal interruption. They are more likely to use conversation as a method of gaining information and establishing status Females may report higher levels of trust in short-duration virtual teams because they are initially more trusting.
The findings revealed that there was a gender difference between male and female students in terms of sociability. The mean scores of the male students among the items were higher than that of female students. There was a statistically significant difference between the scores (t = 1.723, df = 48, p < 0.01), (t = 1.033, df = 48, p < 0.036). The mean scores of the female students among the items were lower than that of male students on Gender differences and Gender sensitivity in friendship making. There was a statistically significant difference between the scores (t=2.269, df = 47, p < 0.00). The result of the one-way analysis of variance showed that there was a significant relationship between the sex of the student and attitude towards making and keeping friends (F (1, 48 = 4.112, p < 0.048). There was a significant relationship between the tribe of the student and having opposite sex friend (F (1, 47 = 4.830, p < 0.033).There was also a significant relationship between religion (F (2, 46 = 4.147, p < 0.02) and tribe (F (2, 46 = 5.928, p < 0.01) of the students with sociable characteristics. The study concluded that gender differential is an important factor in establishing consistency and feelings of connectedness among individuals. The findings also gave an insight to the understanding of psychological processes that underlie the adoption of positive social identity.
Rare Case of Colonic Perforation From Disseminated Fungal Infection in Immunocompetent Patient
Authors: Cheong Ju Yong , Faraj Shadi 
Published: May 2023

Introduction
Fungal infection is a serious complication seen in immunosuppressed patients. Fungal dissemination and infection of the intestine is a rare complication noted in the literature. We report an extremely rare case of colonic perforation from dissemination fungal infection in an immunocompetent patient.

Case presentation
A 76-year-old man presented with a 1-week history of pneumonia-like symptoms of fever, lethargy, productive cough, and night sweats. On examination he was hypotensive and hypoxic. Chest X-ray showed bilateral diffuse consolidation. Peripheral blood showed raised white cell count and inflammatory markers. His background history included chronic lymphocytic leukemia for which he has been in remission for over 7 years. Preliminary diagnosis of pneumonia was made and the patient was started on intravenous antibiotics. His condition deteriorated over the course of 3 weeks, culminating in multi-organ failure, including acute renal failure requiring dialysis, respiratory failure requiring intubation, and hypotension requiring inotropic support. Culture of bronchial washing revealed growth of Pseudomonas aeruginosa and Candida glabrata. On the 19th day of admission, the patient's condition further deteriorated with colonic perforation and feculent peritonitis. Emergency laparotomy with removal of involved colon and end colostomies were performed. Histopathology of the involved colon showed 1.5 cm perforation with inflammatory infiltration. Histopathologic staining showed angioinvasive fungal infection with Aspergillus.

Discussion/conclusion
Aspergillus usually spreads hematogenously from the lungs. Gastrointestinal involvement is difficult to diagnose as the symptoms are often vague and masked by other systemic symptoms. Computed tomography scan can show bowel wall thickening. However, often the diagnosis is only made postoperatively.
Learning to cyberbully: Longitudinal relations between cyberbullying attitudes and perpetration and the moderating influence of participant sex: A brief report
Authors: Barlett Christopher P. , Coyne Sarah M. 
Published: May 2023

AbstractScholars have contended that cyberbullying perpetration is a learned social behavior, and one way to show evidence for cyberbullying learning is to test the longitudinal reciprocal relationships between cyberbullying behavior and related cyberbullying‐related cognitions (e.g., attitudes). A paucity of research has tested these learning tenets, and no research that we are aware of has examined the moderating role of sex. The current study used a two‐wave longitudinal design with US youth. Participants completed measures of cyberbullying attitudes and perpetration. Results showed that early cyberbullying attitudes and behavior predicted later cyberbullying attitudes and behavior; however, and most importantly, sex moderated those relationships. Males had stronger longitudinal relationships than females. Results are interpreted regarding theory.

BackgroundCardiovascular disease is the most common cause of death in people with gout. Acute inflammation, which is a characteristic of gout, may have a mechanistic role in major adverse cardiovascular events (MACEs). We aimed to examine the relationship between admissions to a hospital with acute gout and MACEs in a large population‐based data set.MethodsWe extracted data from the Hospital Morbidity Data Collection and Death Registrations of the Western Australian Rheumatic Disease Epidemiology Registry. We identified patients admitted to hospital with incident acute gout and who had admissions or a death record because of MACEs. We compared the risk of MACEs during the postdischarge period (1‐30 days after acute gout admission) and control period (365 days prior to admission and 365 days after the postdischarge period) using a self‐controlled case‐series (SCCS) design, which is a within‐person design that controls for time‐invariant patient‐specific confounding. We performed conditional fixed‐effects Poisson regression to obtain rate ratios (RRs).ResultsWe identified 941 patients (average age: 76.4 years; SD: 12.6; 66.7% male) with an incident acute gout admission and documented MACEs during the control and/or postdischarge periods. Of the 941 patients, 898 (95%) experienced MACEs during the combined control period (730‐day period) and 112 (12%) during the postdischarge period (30‐day period). The rates of MACEs during the total control and postdischarge periods were 0.84 and 1.45 events per person‐year, respectively. Regression analysis confirmed increased rate during the postdischarge period (RR: 1.67; 95% CI: 1.38‐2.03) compared with the control period. Sensitivity analyses indicated that our results were robust in relation to known limitations of the SCCS design.ConclusionWe report an increased risk of MACEs in the first 30 days after an incident hospital admission with acute gout, suggesting a temporal association between acute inflammation and subsequent MACEs in patients with gout.

ObjectivePatients with autoimmune rheumatic diseases (ARDs) are at greater risk of COVID‐19 infection and hospitalization, increasing the stress and uncertainty already associated with unpredictable conditions. These may be heightened for patients with ARDs from underrepresented minority backgrounds. This study aimed to explore patient experiences and ARD‐related challenges during the first year of the pandemic.MethodsBetween December 2020 and May 2021, 60‐minute semistructured interviews were conducted with English‐ and Spanish‐speaking adults, aged 18 years or older with self‐reported diagnosis of ARD, via phone or videoconferencing using an interview guide on living with an ARD during the pandemic. Analysis combined methods of phenomenology and content analysis through three steps: 1) summarizing interviews, 2) iteratively refining units of meaning, and 3) axial and selective coding to determine cross‐cutting themes. Study procedures were conducted by a multidisciplinary team, a majority also diagnosed with ARDs.ResultsThe research team interviewed 22 patients (39.8 ± 15.7 years old; 82.8% female; 31.8% Hispanic or Latino/a/x) with ARDs. Themes included 1) information access and understanding, 2) problem solving access to health care, 3) balancing risks, and 4) mental health implications. Within these themes, patients from underrepresented minority backgrounds faced unique challenges.ConclusionPatients with ARDs require direct and timely communication about their risk of COVID‐19 morbidity and mortality and require increased support for psychosocial and ARD‐related implications of the pandemic. Health care systems must consider ways to support patients who are balancing chronic disease management with risk reduction for contracting emerging COVID‐19 variants.

Published: May 2023

AbstractMolecular spins are promising building blocks of future quantum technologies thanks to the unparalleled flexibility provided by chemistry, which allows the design of complex structures targeted for specific applications. However, their weak interaction with external stimuli makes it difficult to access their state at the single‐molecule level, a fundamental tool for their use, for example, in quantum computing and sensing. Here, an innovative solution exploiting the interplay between chirality and magnetism using the chirality‐induced spin selectivity effect on electron transfer processes is foreseen. It is envisioned to use a spin‐to‐charge conversion mechanism that can be realized by connecting a molecular spin qubit to a dyad where an electron donor and an electron acceptor are linked by a chiral bridge. By numerical simulations based on realistic parameters, it is shown that the chirality‐induced spin selectivity effect could enable initialization, manipulation, and single‐spin readout of molecular qubits and qudits even at relatively high temperatures.

AbstractIII‐V colloidal quantum dots (CQDs) are promising materials for optoelectronic applications, for they avoid heavy metals while achieving absorption spanning the visible to the infrared (IR). However, the covalent nature of III‐V CQDs requires the development of new passivation strategies to fabricate conductive CQD solids for optoelectronics: this work shows herein that ligand exchanges, previously developed in II‐VI and IV‐VI quantum dots and employing a single ligand, do not fully passivate CQDs, and that this curtails device efficiency. Guided by density functional theory (DFT) simulations, this work develops a co‐passivation strategy to fabricate indium arsenide CQD photodetectors, an approach that employs the combination of X‐type methyl ammonium acetate (MaAc) and Z‐type ligands InBr3. This approach maintains charge carrier mobility and improves passivation, seen in a 25% decrease in Stokes shift, a fourfold reduction in the rate of first‐exciton absorption linewidth broadening over time‐under‐stress, and leads to a doubling in photoluminescence (PL) lifetime. The resulting devices show 37% external quantum efficiency (EQE) at 950 nm, the highest value reported for InAs CQD photodetectors.
A Significant Two‐Dimensional Structural Transformation in a Coordination Polymer that Changes Its Electronic and Protonic Behavior

Published: May 2023

AbstractA 2D‐to‐2D (2D: two‐dimensional) structural transformation accompanying significant bond rearrangement and coordination environment change is demonstrated in a coordination polymer (CP) comprised of copper(II) ions and terephthalate (BDC2−) ligands for the first time. When immersed in water, a free‐standing membrane of 2D Cu(BDC)(DMF) (Cu‐1; DMF: N,N‐dimethylformamide) transforms into 2D Cu(BDC)(H2O)2 (Cu‐2) while maintaining its highly oriented layered structure. In the 2D sheet, paddlewheel‐type CuII dimers coordinated with four bidentate BDC ligands in a square‐planar array in Cu‐1 were released to form uniform aqua‐bridged CuII chains, which are cross‐linked with each other by unidentate BDC ligands, in Cu‐2. The present facile approach to implement the 2D‐to‐2D transformation accompanied by bond rearrangement, which is characteristic of CPs, leads to a marked increase in in‐plane magnetic susceptibility and proton conductivity. In situ experiments in support of theoretical calculations unveiled the energy diagram that governs the unique structural transformation.

Abstractβ‐NaYF4 nanocrystals are a popular class of optical materials. They can be doped with optically active lanthanide ions and shaped into core‐multi‐shell geometries with controlled dopant distributions. Here, we follow the synthesis of β‐NaYF4 nanocrystals from α‐NaYF4 precursor particles using in situ small‐angle and wide‐angle X‐ray scattering and ex situ electron microscopy. We observe an evolution from a unimodal particle size distribution to bimodal, and eventually back to unimodal. The final size distribution is narrower in absolute numbers than the initial distribution. These peculiar growth dynamics happen in large part before the α‐to‐β phase transformation. We propose that the splitting of the size distribution is caused by variations in the reactivity of α‐NaYF4 precursor particles, potentially due to inter‐particle differences in stoichiometry. Rate equation modeling confirms that a continuous distribution of reactivities can result in the observed particle growth dynamics.
A comprehensive proposed model for gas separation prediction of mixed matrix membranes containing tubular fillers
Authors: Feijani Elahe Ahmadi , Rezakazemi Mashallah 
Published: May 2023

AbstractIn this study, a comprehensive model based on composite modulus prediction model named Takayanagi is rendered which can reasonably describe gas performance of tubular filler contained mixed matrix membrane (MMMs) by considering any possible interfacial morphology. Interphase thickness (t), interphase permeability (Pi), and percolation threshold concept are included in proposed model to accurate description of the MMM performance. Since tubular fillers can be in different surface area with the same chemistry, mechanical properties are useful for determination of interphase thickness based on Pukanszky approach. On the other hand, the maximum separation potential of tubular filler can be estimated by the proposed model. In order to examine the proposed model, polyvinylidene fluoride based MMMs containing pristine and acid modified multiwalled carbon nanotube are fabricated and characterized. The interphase morphology and contribution of carbon nanotubes in gas permeability of the constructed MMMs are interpreted in details by the proposed model.
Structures and Mechanisms of a Novel Bacterial Transport System for Fatty Acids
Authors: Zhai Liting , Chou Jonathan Chiu‐Chun , Oo Hannah , Dassama Laura M. K. 
Published: May 2023

AbstractBacterial acquisition of metabolites is largely facilitated by transporters with unique substrate scopes. The tripartite ATP‐independent periplasmic (TRAP) transporters comprise a large family of bacterial proteins that facilitate the uptake of a variety of small molecules. It has been reported that some TRAP systems encode a fourth protein, the T component. The T‐component, or TatT, is predicted to be a periplasmic‐facing lipoprotein that enables the uptake of metabolites from the outer membrane. However, no substrates were revealed for any TatT and their functional role(s) remained enigmatic. We recently identified a homolog in Methylococcus capsulatus that binds to sterols, and herein, we report two additional homologs that demonstrate a preference for long‐chain fatty acids. Our bioinformatics, quantitative analyses of protein‐ligand interactions, and high‐resolution crystal structures suggest that TatTs might facilitate the trafficking of hydrophobic or lipophilic substrates and represent a new class of bacterial lipid and fatty acid transporters.
CYPArm2 is a CYP450 Monooxygenase with Protoilludene 13‐Hydroxylase Activity Involved in the Biosynthesis of Armillyl Orsellinate‐Type Sesquiterpenoids

Published: May 2023

AbstractThe melleolides are a family of structurally and functionally diverse sesquiterpenoids with potential applications as fungicides, antimicrobials, and cancer therapeutics. The initial and terminal steps of the biosynthesis pathway in Armillaria spp. have been characterized, but the intermediate steps are unclear. Biosynthetic gene clusters in A. mellea and A. gallica were shown to encode a terpene cyclase, a polyketide synthase, and four CYP450 monooxygenases. We have characterized CYPArm3, which is responsible for the hydroxylation of Δ‐6‐protoilludene, but the functions of the other CYP450s remain to be determined. Here we describe CYPArm2, which accepts Δ‐6‐protoilludene and 8α‐hydroxy‐6‐protoilludene as substrates. To investigate the products in more detail, we generated recombinant Saccharomyces cerevisiae strains overexpressing CYPArm2 in combination with the previously characterized protoilludene synthase and 8α‐hydroxylase. Using this total biosynthesis approach, sufficient quantities of product were obtained for NMR spectroscopy. This allowed the identification of 8α,13‐dihydroxy‐protoilludene, confirming that CYPArm2 is a protoilludene 13‐hydroxylase.
