Two scholars, Rodriguez-Leyva and Pierce, present the cardiac and haemostatic effects of dietary hempseed to show people the benefit and nutritional value of hemp. Hemp, also known as Cannabis sativa L., belongs to the Cannabaceae family, and it is used widely in food, fiber, medicine and drugs. Hempseed has abundant of nutrition such as a large amount of protein and Vitamin E. Most importantly, it contains all kinds of daily necessary amino acids while producing a high quantity of amino acid arginine that is good for the cardiovascular system. During metabolism, amino acid arginine plays an important role as producer of nitric oxide, which is a molecule that runs as a significant message transmitter in heart and vassals system. To be specific, it helps control the “regulation of vascular tone, homeostasis of blood pressure and proliferation of vascular smooth muscle cells” (CITE). The hempseed has a rich content of linoleic acid, which reduces the cholesterol level of the body, and low cholesterol helps decrease the risk of heart attack. It also contributes in regulation and avoidance of blood pressure. (Rodriguez-Leyva and Pierce). Their arguments mainly focus on the contribution of hemp in human health. By pointing out the important nutrient value of hemp, authors…

    Arginine vasopressin (AVP) maintains osmolality by regulating water reabsorption in the principal cells of the kidneys’ renal collecting duct. AVP is synthesized in the hypothalamus and released by the neurohypophysis. AVP binds to the G-protein couple receptor, arginine vasopressin receptor type 2 (AVPR2), in the basolateral membrane of the kidneys. This leads to transport of aquaporin water channels (AQP2) to the apical membrane of the collecting duct principal cells. Water permeability is…

    efficacious in the treatment of liver diseases and wound healing [11]. It can also be used as a precursor for the synthesis of other amino acids, such as arginine and citrulline, and putrescine, an important diamine used as a nylon precursor [28]. L-Ornithine could be produced by fermentation using auxotrophic mutants, for example, citrulline- or arginine-required mutants of Acinetobacter lwoffi and Coryneform bacterium obtained by traditional mutagenesis [1,6,18]. However, the product yield of…

    will be needed to help meet fluid demands. Arginine is a conditionally essential amino acid. It is necessary during periods of growth and healing. A patient without wounds does not typically need additional arginine added into their nutrition regime. However, when a pressure ulcer is present, often the patient is deficient in arginine. 7-25 grams per day has shown greater protein and hydroxyproline, a precursor to collagen in the wound bed. It has enhanced T-lymphocyte function for immunity…

    In 1999, researchers studied the effects of L-arginine on erectile dysfunction, and thirty-one percent of men who took 5 grams of L-arginine a day experienced improvements in sexual function. In addition, another study showed that when combined with pycnogenol, a plant product that is derived from tree bark, sexual ability was restored to 80 percent of the participants after two months. After three months, ninety-two percent had restored sexual…

    micropinocytosis, and even clathrin mediated endocytosis have been proposed as possible translocation mechanisms, but it is direct translocation and endocytosis that have been given the most support as the probable mechanisms (Farkhani et al, Deshayes et al., Koren and Torchilin, Dupont et al.). MAP (model amphipathic peptide) is an amphipathic CPP which exhibits an -helical secondary structure (Deshayes et al., Oehlke et al.). It was first designed by Steiner et al. and has since had many…
