The study was undertaken to analyze the state of visual, cardiovascular and antioxidant systems along with peripheral blood exposed to laser emission with the wavelength of 10.6 mm and energetic exposure equal to that of threshold (21 J.cm2) and subthreshold (1/7 of the threshold value). Not only local but also general changes were detected. The cardiovascular and antioxidant systems were most sensitive to this type of exposure. The degree of changes was dose-dependent.

Background: Osteoporosis is a chronic condition characterized by reduced bone strength and an elevated risk of fractures. The influence of diet and glucose metabolism on bone health and the development of osteoporosis has been an area of interest. This study aimed to investigate the potential association between dietary glycemic index (DGI), dietary glycemic load (DGL), dietary insulin index (DII), dietary insulin load (DIL), and the odds of osteoporosis among Iranian adults.

Dynamic high-pressure microfluidization (DHPM) is an emerging treatment technology and has been widely used for the recovery of natural polysaccharides. The aim of the present contribution is to discuss the DHPM-assisted extraction and processing of polysaccharides from some foods and by-products by reviewing the instrument and working principle, procedures, key parameters, and effects of DHPM on the structures, food properties, and bioactivities of resulting polysaccharides. It was found that a DHPM instrument with Z-type chamber is preferable for extracting polysaccharides, and a DHPM with Y-type chamber is applicable for processing polysaccharides.

Background: One-carbon metabolism links folate and methionine metabolism and this is essential for nucleotide synthesis in the cells. Alterations in one-carbon metabolism are associated with cardiovascular disease (CVD), type 2 diabetes and cancer. Our aim was to investigate whether SNPs in antioxidant-enzyme genes impact the concentrations of folate in serum (s-folate), plasma total homocysteine (p-tHcy) and total glutathione in plasma (p-tGSH) in healthy subjects after supplementation with folic acid.

Melatonin (MEL), functioning as a circulating hormone, is important for the regulation of ferroptosis in different health scenarios and acts as a crucial antioxidant in cardiovascular diseases. However, its specific function in ferroptosis related to myocardial ischemia-reperfusion injury (MIRI) remains to be fully elucidated. In our research, we utilized a rat model of MIRI induced by coronary artery ligation, along with a cell model subjected to hypoxia/reoxygenation (H/R).
