Objective: Aging is a multifactorial phenomenon, which attribute to different diseases and abnormalities in living systems. Oxidative stress, which is an important factor in aging, exacerbates this process via different mechanisms. Crocin (CR), one of the active components of saffron showed strong antioxidant effects. In the present study, anti-aging property of crocin was investigated in mice....

The polysaccharide exuded by Acacia decurrens trees contains residues of D-galactose , LArabinose , L-Fucose and Dglucuronic acid. An examination of the OMethyl derivatives of the gum yields 2,3,4,6 tetra –O-methyl –D-galactose, 2,3 –di-O-Methyl –L-arabinose , 2,3,4-triO-methyl-D-galactose, 2,4-di-O-methyl-D-galactose together with 2,3,4 tri-O-methyl-Dglucuronic acid by acid hydrolysis. The deg...

Gracilariopsis lemaneiformis polysaccharide (GP) exerted protective effects in an aging mouse model administered with D-galactose, and its mechanism was revealed. GP increased the activity of antioxidant enzymes, reduced malondialdehyde levels brain serum, alleviated D-galactose–induced damage to liver, ameliorated mild cognitive impairment. Abundance gut microbiota differed significantly betwe...

Background: Spleen plays a role in human immune system as well recycling and filtering blood. The aging spleen is associated with fibrosis impaired system, increasing individual vulnerability to getting infections. Regular physical activity essential maintain enhance body fitness, endurance, system.Objective: This study aimed investigate the effects of mild moderate-intensity treadmill exercise...

introduction: d-galactose (d-gal) is well known as an appropriate agent to induced aging effects in the in vivo and in vitro models. in the present study, we selected crocin, the main constituent of crocus sativus l. (saffron), against d-gal cytotoxicity in human neuroblastoma sh-sy5y cells. materials and methods:  cells were pretreated with crocin (25-500 µm) for 24 h and then exposed to d-gal...

D-galactose induces pancreatic disorder along with aging mouse model. Vitex agnus-castus (VAC) has potential pancreatic protective effect. Hence, this study was designed to evaluate the hypoglycemic and pancreas protective effects of VAC hydroalcoholic extract in D-galactose-induced aging female mice. In the present experimental study, 72 adult female Naval Medical Research Institute (NMRI) mic...

The two optical forms of aldohexose galactose differing at the C-1 position, alpha-D-galactose and beta-D-galactose, are widespread in nature. The two anomers also occur in di- and polysaccharides, as well as in glycoconjugates. The anomeric form of D-galactose, when present in complex carbohydrates, e.g., cell wall, glycoproteins, and glycolipids, is specific. Their interconversion occurs as m...
