objective(s):alzheimer's disease (ad) is the most common age-related neurodegenerative disorder. one of the hallmarks of ad is an abnormal accumulation of fibril forms of tau protein which is known as a microtubule associated protein. in this regard, inhibition of tau aggregation has been documented to be a potent therapeutic approach in ad and tauopathies. unfortunately, the available syn...

drought is one of the most important factors limiting crop yields around the world. drought stress in plants, the change (increase or decrease) in the production of plant proteins. this research was carried out using bread wheat genotypes. for evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....

Reactive oxygen species (ROS)plays an important role in sperm motility. The physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. Meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

studies on the genes contributing to the seed filling in chickpea and its protein content might be valuable in engineering plants with seeds of a higher nutritional value. a gene of interest is phosphoenolpyruvate carboxykinase (pepck), encoding a protein with a substantial role in the gluconeogenesis pathway. in the present study, the protein content (percentage) was measured in a number of cu...

brain edema plays an important role in secondary tissue damage following traumatic brain injury (tbi) but the underlying mechanisms are not entirely elucidated. the g protein coupled receptor fm-4 and its ligands, neuromedin s (nms) and neuromedin u (nmu), are expressed in diverse brain areas, and have a variety of roles in nociception, inflammation, and stress but their probable changes after ...

we encountered a patient with methylmalonic aciduria associated with skin lesions resembling acrodermatitis enteropathica. this child was being fed with a low-protein diet when the skin disorder developed. a deficiency in plasma levels isoleucine, was confirmed. supplementation of a high-caloric, protein-rich diet led to a prompt improvement of skin lesions. we assume that in our patient the sk...

Low fat mayonnaise as a low-calorie product modification has low emulsion stability. Whey Protein Concentrate (WPC) high protein content and can act good emulsifier for of mayonnaise. The purpose this study was to evaluate low-fat using WPC based on pH, moisture content, viscosity, content. materials used are egg yolk, sunflower seed oil, vinegar, WPC, other complementary materials. This labora...

Protein–protein binding enables orderly biological self-organization and is therefore considered a miracle of nature. Protein‒protein driven by electrostatic forces, hydrogen bonding, van der Waals force, hydrophobic interactions. Among these physical only interactions can be long-range intermolecular attractions between proteins due to the shielding surrounding water molecules. Low-entropy hyd...
