Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

Spatial Detection of Microsphere Polystyrene Plastics and Molecular Remodeling within a Full‐Body Mouse with MALDI Trapped Ion Mobility Mass Spectrometry Imaging

open access: yesAngewandte Chemie, EarlyView.
Orally administered polystyrene microplastics accumulate in murine tissues and are detected using MALDI‐MSI with TIMS. Lipid profiling reveals decreases in hexosylceramides, sphingomyelins, and ether‐linked phospholipids, indicating altered metabolism.

Complementary multi‐omics profiling of chronic thromboembolic pulmonary hypertension reveals immune cell alterations, epigenetic changes, and genetically supported candidate genes

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study presents an integrative multi‐omics framework to uncover the molecular mechanisms and potential biomarkers of chronic thromboembolic pulmonary hypertension (CTEPH). Anthropometric and biochemical data were correlated using canonical correlation analysis, revealing key cardiometabolic associations. Single‐cell RNA sequencing identified immune

A high‐fat diet with vitamin D and propylthiouracil produces a pro‐atherogenic phenotype in rats

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Male Sprague–Dawley rats received a cholesterol‐rich high‐fat diet supplemented with vitamin D and propylthiouracil for 11 weeks. The model induced dyslipidemia (increased total cholesterol/low‐density lipoprotein, decreased triglycerides), inflammation (increased interleukin‐6 and serum amyloid A), hypercalcemia, and reduced circulating endothelial ...

PCSK9 molecular bridge between hyperlipidemia and vascular inflammation: novel insights into PCSK9-centered pathways in atherosclerosis: a comprehensive review

open access: yesBeni-Suef University Journal of Basic and Applied Sciences
Background Atherosclerosis remains a leading cause of cardiovascular morbidity and mortality despite advances in lipid-lowering therapy. The proprotein convertase subtilisin/kexin type 9 protein (PCSK9) was originally characterized for promoting ...

Blood Lactate as a Prognostic Biomarker for Survival and Weight Loss in Amyotrophic Lateral Sclerosis: An Exploratory–Validation Study

open access: yesAnnals of Neurology, EarlyView.
Objective Lactate is increasingly recognized as an energy substrate, but its relevance to amyotrophic lateral sclerosis (ALS) remains unclear. We examined whether blood lactate is associated with survival and weight loss in ALS. Methods This retrospective study included an Australian exploratory cohort and a Japanese validation cohort with clinical ...

Effects of Various Levels of Oxidized Oil on Performance, Egg Quality and Some Blood Metabolites in Laying Hens [PDF]

open access: yesPoultry Science Journal, 2016
The influence of dietary oxidized oil was studied on laying hen performance, egg quality and blood metabolites.  Experiment was conducted on 160 laying hens (Hy-Line W-36, 54-61 wk of age) in a completely randomized design with five treatments and four ...
