Arginine is considered a semi-essential amino acid because even though the body normally makes enough of it, supplementation is sometimes needed. For example, people with protein malnutrition, excessive ammonia production, excessive lysine intake, burns, infections, peritoneal dialysis, rapid growth, urea synthesis disorders, or sepsis may not have enough arginine. Symptoms of arginine deficiency include poor wound healing, hair loss, skin rash, constipation, and fatty liver.
Arginine changes into nitric oxide, which causes blood vessel relaxation (vasodilation). Early evidence suggests that arginine may help treat medical conditions that improve with vasodilation, such as chest pain, clogged arteries (called atherosclerosis), coronary artery disease, erectile dysfunction, heart failure, intermittent claudication/peripheral vascular disease, and blood vessel swelling that causes headaches (vascular headaches). Arginine also triggers the body to make protein and has been studied for wound healing, bodybuilding, enhancement of sperm production (spermatogenesis), and prevention of wasting in people with critical illnesses.
Arginine hydrochloride has a high chloride content and has been used to treat metabolic alkalosis. This use should be under the supervision of a qualified healthcare professional.
The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes respiratory coronavirus disease 2019 (COVID-19) triggered an unprecedented public health emergency. Human mobility patterns were fundamental to the spread of SARS-CoV-2 globally. The situation is particularly acute in a country like Saudi Arabia, which has seen more than 750,000 cases and over 9,000 deaths as of March 30th, 2022.
A new study assessed the molecular dynamics of potentially active natural phytochemicals to target the SARS-CoV-2 main protease.
A team of international scientists has developed an mRNA-based coronavirus disease 2019 (COVID-19) vaccine encoding the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) delta variant. The vaccine candidate has shown high efficacy in inducing neutralizing antibodies and protecting against delta infection in mice. The study is currently available on the bioRxiv* preprint server.
In a new study, researchers aimed to determine if peptidyl-arginine deiminases inhibitors may be used as a novel class of host-targeting antivirals against human coronaviruses.
Researchers investigate innate and adaptive immune responses at both the early and late stages of SARS-CoV-2 infection.
Researchers evaluate the virucidal effects of ELAH against SARS-CoV-2 and human coronavirus-229E in a nasal spray formulation.
In a recent study posted to the bioRxiv* preprint server, researchers presented the intragenomic rearrangements of β-coronaviruses (CoVs), including severe acute respiratory syndrome CoV 2 (SARS-CoV-2).
A recent study assessed the mechanism by which SARS-CoV-2 Omicron and Alpha VOCs inhibit the SARS-CoV-2 spike protein and mitigate the risk of a multisystem inflammatory syndrome in children.
Athletes and the general population alike train to promote health and physical fitness. With repeated exposure to the minimal stress of exercise, the body adapts.
Researchers examined how SARS-CoV-2 variants of concern differentially use an additional metalloproteinase-dependent entry pathway to enter the host cells.
Autoimmune diseases are triggered when the immune system malfunctions and attacks the body's own structures.
A recent study reported the abrogation of inhibition of the NK cells by a SARS-CoV-2-encoded protein presented by HLA-E.
A study recently accepted for publication in The Journal of Clinical Investigation describes a new and effective therapy to treat glioblastoma: the concomitant use of ADI-PEG20 together with focal brain radiotherapy.
A new study explains how SARS-CoV-2 adapts its immunogenicity to the immune response of the host.
A recently published paper in the journal Molecular Cancer by the group of Dr. Manel Esteller, Director of the Josep Carreras Leukaemia Research Institute, ICREA Research Professor and Genetics Chairman at the University of Barcelona, shows that transfer RNAs for certain amino acids are altered at the epigenetic level in some types of cancer, expressing it in an exaggerated manner in some cases and being deficient in others.
A new study was based on the hypothesis that competitively inhibiting cellular furin and selectively targeting SARS-CoV-2 in the infected viral-producing cells is critical for therapeutic specificity.
A new dietary tool to quickly and accurately assess micronutrient levels aims to help cancer patients fight disease, paving the way to find better nutritional solutions for oncology services, Flinders University researchers say.

Researchers evaluate how the D614G and P681H mutations alter the attributes of SARS-CoV-2 VOCs.
Researchers from China summarized the representative structures of SARS-CoV-2 proteins and discussed the development of novel therapeutic agents for targeting these proteins to treat and prevent COVID-19.
