Arginine

system release of epinephrine and norepinephrine from the adrenal glands causing constriction of arteries to increase blood pressure. The activation of the renin-angiotensin-aldosterone cycle leads to the retention of sodium and water, release of arginine vasopressin and endothelin (increases BP by vasoconstriction, afterload, and heart rate), and the release of cytokines that leads to ventricular remodeling by hypertrophy of the heart and dilation of the ventricles and decreased…

Proximate analysis The analysis result of proximate composition of dried laver (P. species) has presented in Table 1. In our study, the crude protein of commercial dried laver was found to be (42.99 ± 0.051g/100g DW) and the moisture content was (9.40 ± 0.056 g/100g DW). The ash content was found (10.30 ± 0.033 g/100g DW). Laver, in this study, contained a very small amount of crude lipids (0.49 ± 0.04 g/100g DW). The total dietary fibre of dried laver was (31.63 ±0.032 g/100g DW). The total and…

differences, yet we cannot disregard those environmental factors and empirical evidence. A majority of literature has been focusing on how OT influence prosocial behaviour, direction for future studies can be carried out on the role of VP, in particular, arginine vasopressin (AVP) is exerting greater influence on maternal behaviour as well as a healthy behavioural development of…

proteomic analysis. Only a few proteases that are useful for proteomic analysis. For instance, trypsin and chymotrypsin are often used to cleave proteins at selective amino acid residues. Trypsin cleaves on the C-terminal side of the lysine and arginine amino acids, whereas chymotrypsin cleaves after the aromatic amino acids. Trypsin exhibits higher activity and narrower specificity compared to chymotrypsin. When the lysine reside is modified or flanked by proline, cleavage of trypsin is…

When you hear the Phenylketonuria, what do you think? Is it that you have never heard that word be used before? It could just be that you think it can be a very harmful disorder to the human body. There are many questions that are asked about Phenylketonuria (PKU), and many of those can be answered easily. PKU is a birth defect that causes an amino acid to build up in your body. This defect/disorder can be treated in a multitude of different methods. If it is left untreated it can lead to…

Wang et al. (2015) formulated a solid dispersion to improve the solubility and bioavailability of Ginkgo biloba extract (GE) through hot melt technology. The polymer studied were Kollidon® VA64/Kolliphor® RH40 (85:15) and the extrusion was carried out at 120-125⁰C with 100 RPM with 25% drug load. DSC and XRD studies confirmed the amorphous conversion of the GE and the dissolution carried in 250ml of 0.1N HCl showed that the dissolution of solid dispersion of GE was significantly improved (2-3…

It is also called anabolism or biogenesis. It is a enzyme-catalyzed method in which substrates are transformed into complex products. In this process simple compounds change or convert into other compounds or they join together to form macromolecules. Example: In this process gluneogenesis is responsible for the production of glucose from non carbohydrate originator. Actually biosynthesis is an enzyme-catalyzed process in which substrates are converted into complex compounds. 1. Biosynthesis…

increased reactions cause amplified neurosensory signals to be formed in the paraventricular nucleus of the hypothalamus and in the locus coeruleus-noradrenergic centre. In response, the hypothalamus emits cortcotropin-releasing factor (CRF) and arginine vasopression, which triggers the HPA axis, controlling the release of pituitary peptides manufactured by differential cleavage of pro-opiomelanocortin, particularly by adrenocorticotrophic hormone, encephalin, and endorphins.…

Problem Statement: Can supplements help with anxiety patients better than medications that are designed to treat it? Research/ Review of Literature: An experiment that was conducted by Shaheen Lakhan and Karen Vieira (2010) found that patients who suffer from an anxiety disorder/ depression could benefit from having a supplement x, which contains kava, that will reduce anxiety. The experiment had two groups. The first group was patients that were diagnosed as having anxiety or depression…

Is Oxytocin a potential treatment for social deficits in Autism Spectrum Disorders? A principal feature of autism spectrum disorders (ASDs) is a deficit in social interaction and empathy. In animal and in (some human) studies, oxytocin administered as intranasal spray has demonstrated improved social interactions. Past and current studies have provided some genetic evidence that suggests oxytocin pathways in the brain might be deficient in patients with ASDs, although conflicting evidence has…
