Scope: This study investigated the global transcriptional and metabolic changes occurring at multiple time points over 24 wk in response to a high-fat diet (HFD).

Methods And Results: C57BL/6J mice were fed a HFD or normal diet (ND) over 24 wk. HFD-fed mice developed early clinical indicators of obesity-related co-morbidities including fatty liver, insulin resistance, hyperglycemia and hypercholesterolemia. Time-course microarray analysis at eight time points over 24 wk identified 332 HFD responsive genes as potential targets to counteract diet-induced obesity (DIO) and related co-morbidities. Glucose regulating enzyme activity and gene expression were altered early in the HFD-fed mice. Fatty acid (FA) and triglyceride (TG) accumulation in combination with inflammatory changes appear to be likely candidates contributing to hepatic insulin resistance. Cidea seemed to be one of representative genes related to these changes.

Conclusion: Global transcriptional and metabolic profiling across multiple time points in liver revealed potential targets for nutritional interventions to reverse DIO. In future, new approaches targeting HFD responsive genes and hepatic metabolism could help ameliorate the deleterious effects of an HFD and DIO-related complication.

The current study was deployed to evaluate the role of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and miR-155, along with the inflammatory markers, TNFα and IL-6, and the adhesion molecule, cluster of differentiation 106 (CD106), in Behçet's disease (BD) pathogenesis. The study also assessed MALAT1/miR-155 as promising diagnostic and prognostic biomarkers for BD. The current retrospective case-control study included 74 Egyptian BD patients and 50 age and sex-matched controls.

Deciphering the colostral-immunity transfer: from mammary gland to neonates small intestine.

Vet Res Commun

January 2025

Laboratory of Agricultural Animal Genetics, Breeding and Reproduction of Ministry of Education, Huazhong Agricultural University, Wuhan, China.

Colostrum, the initial mammary secretion produced by various mammals following birth, is a conduit for maternal immunity transfer in diverse mammalian species. Concurrently, many cellular processes are occurring in the neonatal small intestine to prepare it to receive molecular signals from a superfood essential for the neonate's health and development. During the prepartum colostrum secretion, the newborn intestine undergoes transient alterations in the intestinal barrier, primarily regulating immunoglobulin absorption.

Introduction: A hybrid approach with very high-power short-duration (vHPSD) posteriorly and ablation-index guided HPSD (50 W) anteriorly seems to be an optimal balance between efficiency and effectiveness for point-by-point pulmonary vein isolation (PVI). The aim of the current study is to compare vHPSD/HPSD ablation to cryoballoon ablation (CBA) in patients with symptomatic atrial fibrillation (AF).

Methods And Results: In this retrospective single-center study, we identified 110 consecutive patients who underwent their first PVI with either vHPSD/HPSD (n = 54) or CBA (n = 56).

Purpose: A prospective longitudinal cohort study was performed to gain insight into the course of recovery in terms of pain, opioid consumption, and mobility in patients with a lateral compression (LC) pelvic injury.

Methods: Adult patients with an LC injury, without any cognitive disorders or limited mobility and who could communicate in Dutch were asked to participate. Pain in terms of NRS (numeric rating scale, range 0-10), opioid use and mobility were recorded at eight time points: at hospital admission, and three days, one week, six weeks, three months, six months, one year and two years after the injury.

Background: Although both the lateral sagittal and costoclavicular approaches are applied at the cord level in the infraclavicular region, there is a major difference between the distributions of the two approaches. We aimed to investigate the effects of this different distribution on tissue perfusion and oxygenation.

Methods: Sixty patients undergoing elective elbow, forearm, wrist and hand surgery under infraclavicular brachial plexus block were included in the study.
