Inhibition of Retinal Neovascularization by BEZ235: Targeting the Akt/4EBP1/Cyclin D1 Pathway in Endothelial Cells.
Invest Ophthalmol Vis Sci
January 2025
Institute of Ophthalmology, School of Medicine, Jinan University, Guangzhou, China.
Purpose: To investigate the therapeutic efficacy of BEZ235, a dual PI3K/mTOR inhibitor, in suppressing pathological neovascularization in an oxygen-induced retinopathy (OIR) mouse model and explore the role of cyclin D1 in endothelial cell cycle regulation.
Methods: Single-cell RNA sequencing was performed to analyze gene expression and cell-cycle alterations in retinal endothelial cells under normoxic and OIR conditions. The effects of BEZ235 on human umbilical vein endothelial cells (HUVECs) and human retinal microvascular endothelial cells (HRMECs) were evaluated by assessing cell viability, cell-cycle progression, proliferation, migration, and tube formation.
Stem Cell Therapy Modulates Molecular Cues of Vasogenic Edema Following Ischemic Stroke: Role of Sirtuin-1 in Regulating Aquaporin-4 Expression.

Department of Pharmacology and Toxicology, National Institute of Pharmaceutical Education and Research (NIPER), Ahmedabad, Gandhinagar, Gujarat, India.
Background: Conventional post-stroke edema management strategies are limitedly successful as in multiple cases of hemorrhagic transformation is being reported. Clinically, acute-ischemic-stroke (AIS) intervention by endovascular mesenchymal stem cells (MSCs) have shown benefits by altering various signaling pathways. Our previous studies have reported that intra-arterial administration of 1*10 MSCs (IA-MSCs) were beneficial in alleviating post-stroke edema by modulating PKCδ/MMP9/AQP4 axis and helpful in preserving the integrity of blood-brain-barrier (BBB).

Acta Parasitol
January 2025
Laboratory of Parasitic Eco-Epidemiology and Population Genetics, Pasteur Institute of Algeria, Dely-Brahim, Algiers, Algeria.
Purpose: Aedes albopictus, known as the Asian tiger mosquito, is an extensively studied mosquito species recognized for its rapid global expansion and its capacity to transmit a range of viruses such as dengue, chikungunya, Zika, and yellow fever viruses. In 2010, Ae. albopictus was observed for the first time in Tizi-Ouzou, Algeria, and since then has colonized all the northern part of the country until the semi-arid areas.

Curr Obes Rep
January 2025
Clinical and Experimental Endocrinology, Department of Chronic Diseases and Metabolism, University of Leuven, Herestraat 49 - Box 7003, 3000, Leuven, Belgium.
Introduction: Long-term data indicate that patients who underwent metabolic bariatric surgery have a higher risk of developing nutritional complications. Therefore, it is of utmost importance to monitor their nutritional status.
Methods: A scoping literature search was conducted in MEDLINE, EMBASE, CINAHL, and TRIP database to identify clinical practice guidelines for nutritional screening before and after metabolic bariatric surgery from learned societies.
Feed intake, preferences, in vivo digestibility, and nutritional value of tedera (B. bituminosa var. bituminosa) and maralfalfa (Pennisetum purpureum) in Canary sheep.
