Sirtuin 1 mediates the pro-survival effects of vitamin D in angiotensin II-induced hypertrophy of H9c2 cardiomyoblasts.

Background: The role of 1,25-dihydroxyvitamin-D3 (VitD) and sirtuin-1 (SIRT1) in mitigating pathological cardiac remodeling is well recognized. However, the potential for SIRT1 to mediate the inhibitory effects of VitD on angiotensin II (Ang II) -induced hypertrophy in H9c2 cardiomyoblasts remains unclear.

Methods: H9c2 cardiomyoblasts were exposed to Ang II or a combination of VitD and Ang II, both in the absence and presence of SIRT1-specific siRNA.

Designing the pH-sensitive indicator based on starch nanoparticle with bromocresol green for monitoring meat spoilage.

The starch nanoparticle, combined with bromocresol green (BCG), served as a pH-sensitive indicator to monitor meat quality throughout an 8-day refrigerated storage period. The meat samples were sealed in package which the pH-sensitive indicator attached to the interior part of packaging lid. The changes in meat quality were evaluated by total volatile base nitrogen (TVBN), pH, total viable count (TVC), sensory analysis, and color in interval of 0, 3, 5, 7, and 8-days storage at 4°C.

Blood Features Associated with Viral Infection Severity: An Experience from COVID-19-Pandemic Patients Hospitalized in the Center of Iran, Yazd.

Pandemics such as coronavirus disease 2019 (COVID-19) can manifest as systemic infections that affect multiple organs and show laboratory manifestations. We aimed to analyze laboratory findings to understand possible mechanisms of organ dysfunction and risk stratification of hospitalized patients in these epidemics. .

Comparison of different types of liposomal nano structures for microRNA transfection to human mesenchymal stem cell line S1939.

Liposomes are utilized as a drug delivery carrier in various fields of biomedicine. They are synthesized in the nanometer-size range and are becoming a viable drug delivery carrier for the treatment of different diseases. MicroRNAs as regulatory elements could be transferred to cells for changing their morphology or physiology.

Ascorbic Acid Significantly Decreases Creatine Kinase Plasma Levels in an Animal Model of Statin/Fibrate-Induced Myopathy.

Background: Myopathy is one of the side effects of lipid-lowering drugs, especially statins and particularly when combined with a fibrate. To diagnose myopathy and determine its severity, the plasma levels of three enzymes, creatine kinase (CK), aldolase, and lactate dehydrogenase (LDH), are routinely measured. Physical exercise can aggravate the statin-associated muscular disease.
