Objectives: Phosphorus-31 magnetic resonance spectroscopic imaging (P-MRSI) is a non-invasive tool for assessing cellular high-energy metabolism in-vivo. However, its acquisition suffers from a low sensitivity, which necessitates large voxel sizes or multiple averages to achieve an acceptable signal-to-noise ratio (SNR), resulting in long scan times.
Materials And Methods: To overcome these limitations, we propose an acquisition and reconstruction scheme for FID-MRSI sequences.
Physical Activity and Sedentary Behavior on Well-Being and Self-Rated Health of Italian Public Health Medical Residents During the COVID-19 Pandemic: The PHRASI Study.

High workloads and extended work shift greatly limit the opportunities for medical residents to adopt a healthy lifestyle by practicing regular physical exercise. Using data from the Public Health Residents' Anonymous Survey in Italy (PHRASI), this research assessed the associations between physical activity levels and sedentary behavior, well-being, and self-rated health among Italian public health residents (PHRs) during the COVID-19 pandemic. Employing a cross-sectional design, this study utilized the International Physical Activity Questionnaire, the WHO-5 Well-being Index, and the single-item self-rated health to measure physical activity, sedentary behavior, self-rated health, and well-being among PHRs.

Civil and Environmental Engineering, Kookmin University, 77 Jeongneung-ro, Seongbuk-gu, Seoul 136-702, Republic of Korea.
To overcome the limitations of traditional Reverse Osmosis (RO) desalination, Membrane Distillation (MD) has gained attention as an effective solution for improving the treatment of seawater and RO brine. Despite its potential, the formation of inorganic scales, particularly calcium sulfate (CaSO), continues to pose a major challenge. This research aims to explore the scaling mechanisms in MD systems through a combination of experimental analysis and dynamic modeling.

Post-Traumatic Stress Disorder (PTSD) is a multifaceted psychiatric disorder triggered by traumatic events, leading to prolonged psychological distress and varied symptoms. Rat models have been extensively used to explore the biological, behavioral, and neurochemical underpinnings of PTSD. This review critically examines the strengths and limitations of commonly used rat models, such as single prolonged stress (SPS), stress-re-stress (S-R), and predator-based paradigms, in replicating human PTSD pathology.

Exposure to valproic acid (VPA) during embryogenesis has become a valuable tool for modeling neurodevelopmental disorders in animal models such as zebrafish (). This article examines the effects of embryonic exposure to VPA in zebrafish on the basis of 39 articles sourced from PubMed and Google Scholar. We conducted a systematic review and meta-analysis to elucidate the common impacts of VPA exposure and reported that VPA significantly altered development at various levels.
