Hepatitis B virus (HBV) infection is frequent among patients with chronic kidney disease (CKD). HBV reactivation after kidney transplant (KT) is more common in patients with HBsAg+; however, it can also occur in previously infected individuals, particularly those with HBsAg negative and total antiHBc positive (HBsAg-/antiHBcT+). However, reactivation in this population has scarce and conflicting data. This study aimed to assess the reactivation risk in KT recipients with previous HBV infection (antiHBcT+). A retros [...]

This qualitative study explores the mental health challenges faced by Hawaiʻi farmers and allied agricultural producers, focusing on the main stressors they encountered and the coping mechanisms they employed. Through interviews with 77 farmers across all four counties, data revealed that significant stressors for Hawaiʻi farmers were legislative and policy issues, financial and economic concerns, as well as pests and diseases. Farmers employed various coping strategies to mitigate stress, primarily along the lines [...]

In this work, we study the single and double ionization spectra of the , with complexes by applying the four-component algebraic diagrammatic construction and Fock-space coupled cluster methods to extend earlier studies based on less demanding approaches. The computed single and double ionization potentials are in good agreement comparing with the available experimental results. The electronic structures of the cationic molecular systems are carefully investigated by computing accurately single and double ionizatio [...]

Sarcopenia is more common in persons with type 2 diabetes mellitus (T2DM) than in persons without diabetes. There is overlap of some pathophysiologic features of sarcopenia and T2DM. In addition, the risk for sarcopenia is associated with common complications of T2DM including renal disease, cardiovascular disease and neuropathy. Glycemic control in T2DM may have some benefits on sarcopenia. The specific effects of glucose lowering agents on sarcopenia suggest that metformin, insulin, thiazolidinediones and GLP1 re [...]

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder associated with significant heterogeneity in symptoms and comorbid conditions. Studies have shown the value of early and accurate diagnosis in mitigating the associated social and behavioral challenges. Recently, studies have demonstrated the potential of machine learning (ML) models in identifying ASD patterns from neuroimaging, genetic, and behavioral data. However, the limited interpretability of these models poses a barrier to their clinical adopti [...]

Emotion regulation (ER) involves processes by which individuals modulate the intensity, duration, and expression of emotional responses, and its dysregulation is associated with a broad spectrum of psychological disorders. While traditionally conceptualized within psychological frameworks, ER is increasingly recognized as biologically grounded, involving intricate interactions between neurochemical, hormonal, and metabolic systems. This narrative review aims to synthesize current evidence on biochemical substrates [...]

In this study, the researchers explore the effects of COVID-19-related challenges, such as fear and anxiety about COVID-19, the uncertainty of COVID-19, and the recognition of business opportunities for entrepreneurial intentions and business startups. This study used quantitative methods and based their findings on 278 usable samples collected from Egyptian entrepreneurs. Employing the Structural Equation Model (SEM) through SmartPLS4 shows that fear and anxiety arising from the COVID-19 pandemic harm entrepreneur [...]

Functional magnetic resonance imaging (fMRI) is widely used to detect changes in the resting-state brain networks of migraine patients. Functional connectivity fMRI analysis examines the functional organization of the brain based on temporal correlations of blood oxygen level-dependent signal changes in different brain regions. Most previous resting-state fMRI studies have assumed that functional connectivity between brain regions remains relatively stable over time. However, it is now known that the brain is a com [...]

This is a multi-disciplinary paper focused on the preliminary results of deploying laser shock treatment (LST) to ZrO2 ceramics. This work has significance in several industrial sectors for components that will benefit from strengthening. These components are, namely: dental implants; cutting and drawing tools; valves, bearings, pressure vessels, heat exchangers and high-performance scissors and knives, where modification of hard, brittle materials properties such as that of a ZrO2, can yield a performance boost.
