Loss of Mfn1 but not Mfn2 enhances adipogenesis.

Objective: A biallelic missense mutation in mitofusin 2 (MFN2) causes multiple symmetric lipomatosis and partial lipodystrophy, implicating disruption of mitochondrial fusion or interaction with other organelles in adipocyte differentiation, growth and/or survival. In this study, we aimed to document the impact of loss of mitofusin 1 (Mfn1) or 2 (Mfn2) on adipogenesis in cultured cells.

Methods: We characterised adipocyte differentiation of wildtype (WT), Mfn1-/- and Mfn2-/- mouse embryonic fibroblasts (MEFs) and 3T3-L1 preadipocytes in which Mfn1 or 2 levels were reduced using siRNA.

Initial participant perspectives about participating in an online, semi-supervised, cirrhosis-specific nutrition and exercise intervention.

Objectives: In chronic diseases, there have been issues with low levels of participant adherence and retention during well-supported lifestyle behaviour change interventional studies. Theoretically informed, the objective was to explore the types of challenges participants are experiencing to inform future designs.

Design: We conducted an exploratory descriptive study in an adult cirrhosis population after the first 4-6 weeks of a 12-week semi-supervised nutrition and exercise online program.

Sex Differences in Patient-Reported Outcomes and Perception of Ascites Burden Among Outpatients With Decompensated Cirrhosis and Ascites.

Introduction: Perception of the ascites burden and its effects on quality of life may be different between sexes. This study assessed sex differences in perception of ascites burden and its impact on health-related quality of life (HRQoL) in patients with recurrent or refractory ascites.

Methods: The North American Consortium for the Study of End-stage Liver Disease prospectively enrolled outpatients with cirrhosis and large ascites requiring repeat large volume paracenteses.

Toward a Trauma-Informed Comprehensive School Physical Activity Program: Specifying Feasible Practices Across the School Day.

Background: Many students would benefit from trauma-informed physical activity (PA); however, there is a lack of systematic guidance on incorporating trauma-informed practices across school-based PA opportunities. The purpose of this study was to generate a feasible framework for trauma-informed school-based PA.

Methods: Framework development was guided by a modified Delphi approach, including an exploration phase and an evaluation phase.

Abbreviated Multiparametric MR Solution (the "Liver Triple Screen"), the Future of Non-Invasive MR Quantification of Liver Fat, Iron, and Fibrosis.

To review the findings of a multiparametric MRI (the "liver triple screen") solution for the non-invasive assessment of liver fat, iron, and fibrosis in patients with chronic liver disease (CLD). A retrospective evaluation of all consecutive triple screen MRI cases was performed at our institution over the last 32 months. Relevant clinical, laboratory, and radiologic data were analyzed using descriptive statistics.

STRIVE pilot trial: a protocol for a multicentre pragmatic internal pilot randomised controlled trial of Structured TRaining to Improve fitness in a Virtual Environment (STRIVE) before surgery.

Introduction: Home-based, virtually-supported care models may represent the most efficient and scalable approach to delivering prehabilitation services. However, virtual approaches to prehabilitation are understudied. This manuscript describes the protocol for an internal pilot randomised controlled trial of a virtually-delivered, multimodal prehabilitation intervention.

Precise control of neural activity using dynamically optimized electrical stimulation.

Neural implants have the potential to restore lost sensory function by electrically evoking the complex naturalistic activity patterns of neural populations. However, it can be difficult to predict and control evoked neural responses to simultaneous multi-electrode stimulation due to nonlinearity of the responses. We present a solution to this problem and demonstrate its utility in the context of a bidirectional retinal implant for restoring vision.

School-based physical activity during the COVID-19 pandemic.

School closures and restrictions related to the COVID-19 pandemic changed opportunities for youth physical activity (PA). We sought to identify school and other contextual conditions associated with youth PA during the COVID-19 pandemic. A nationally representative, United States sample consisted of 500 parents of children ages 6-10 years old and 500 parent-child dyads with children and adolescents ages 11-17 years old who completed a web-based questionnaire.

Detection of Phenylalanine by Iridium Nanoclusters Using Time-Dependent Density Functional Theory Calculations.

Metal nanoclusters have several applications in biological processes, medicine, cancer therapy, catalysis, etc. Iridium (Ir) nanoclusters exhibit excellent detection behavior compared to their bulk material. This work includes a deep insight into the interaction of Ir nanoclusters of four atoms (Ir) with amino acids and the analysis of Ir-amino acid (Ir-AAc) complexes.

Modernizing behavioral parent training program for ADHD with mHealth strategies, telehealth groups, and health behavior curriculum: a randomized pilot trial.

Objective: Parent behavior management training (BMT) is an evidence-based yet underutilized tool to treat children with ADHD and address related health disparities. This pilot study investigated the acceptability and feasibility of a novel, health behavior-, and technology-adapted BMT (LEAP) vs. standard BMT.

Total energy expenditure measured using doubly labeled water in adults with major chronic diseases: a systematic review.

Background: Energy requirement assessment is a cornerstone for nutrition practice. The extent to which total energy expenditure (TEE; indicator of energy requirements) has been measured in adults with chronic diseases has not been explored.

Objectives: This systematic review aimed to characterize evidence on TEE among individuals with chronic diseases and describe TEE across chronic diseases and in comparison to controls without a chronic disease.

Rationale and design of the multi organ inflammation with serial testing study: a comprehensive assessment of functional and structural abnormalities in patients with recovered COVID-19.

Introduction: Short-term clinical outcomes from SARS-CoV-2 infection are generally favorable. However, 15-20% of patients report persistent symptoms of at least 12 weeks duration, often referred to as long COVID. Population studies have also demonstrated an increased risk of incident diabetes and cardiovascular disease at 12 months following infection.

eMPower: An online Mind-body wellness Program for adults living with chronic health conditions: A three-armed randomized controlled trial protocol.

Background: Symptoms of depression and anxiety are prevalent among adults with chronic health conditions, contributing to reduced quality of life, morbidity, and mortality. Mind-body wellness interventions (i.e.

Methodology for shielding design and evaluation for container scanners.

There has been an increase in the use of high energy photon beam for container scanners in many countries for multi purposes such as detecting high atomic number materials which might be nuclear materials, drugs, high explosive materials and other contrabands etc. High energy photon beams generally 6 and 9 MV can be used for scanning such materials. However, it is important to ensure that radiation level beyond the container scanner installation is within the permissible dose limit specified by the national competent authority for the protection of public and radiation workers.

Move & Thrive: Development of a Web-Based Training for Schools About Trauma-Informed Physical Activity.

Background: Youth who have experienced trauma or other adverse childhood events have the potential to uniquely benefit from physical activity (PA). However, how PA is administered in schools can be re-traumatizing and fail to create positive experiences through movement. We sought to develop role-specific training to help increase the implementation of trauma-informed PA.
