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.
Music is listened in all known cultures. Similarities between human and animal song have been detected: both contain a message, an intention that reflects innate emotional state that is interpreted correctly even among different species.
A team of scientists at The Scripps Research Institute and the University of Virginia has determined the structure of the protein package that delivers the genetic material of the human immunodeficiency virus to human cells.
Scientists have identified the first DNA sequence variant common in the population that is not only associated with an increased risk of heart failure, but appears to play a role in causing it.
One of the challenges of gene therapy - a set of methodologies aimed at treating several nucleic acid diseases - is to assure that this material arrives directly to the nucleus of the cell without losing a substantial amount along the way and without producing any undesired side effects. With this aim, scientists experiment with the use of different types of vectors, molecules capable of transporting genetic material to the correct place.
Aeterna Zentaris Inc. today announced that it has reached agreement with the Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) for Solorel® (AEZS-130, macimorelin) which will enable the Company to complete the ongoing registration study required to gain approval as a diagnostic test for Adult Growth Hormone Deficiency (AGHD).
Functional amino acids play a critical role in the development of both animals and humans, according to a Texas AgriLife Research scientist.
UC Davis researchers have found a new pathway for repairing DNA damaged by oxygen radicals. The results are published this week in the journal Proceedings of the National Academy of Sciences.
Gilead Sciences, Inc. today announced that its head-to-head Phase III clinical trial of Cayston (aztreonam for inhalation solution) versus tobramycin inhalation solution (TIS) in cystic fibrosis (CF) patients with Pseudomonas aeruginosa (P. aeruginosa) achieved its co-primary endpoint of superiority of Cayston for mean actual change in forced expiratory volume in one second (FEV1, a measure of lung function) percent predicted across three treatment cycles (six months).
No matter how you slice it, watermelon has a lot going for it -- sweet, low calorie, high fiber, nutrient rich -- and now, there's more. Evidence from a pilot study led by food scientists at The Florida State University suggests that watermelon can be an effective natural weapon against prehypertension, a precursor to cardiovascular disease.
Two herbal remedies from passion flower extract and kava have shown to be effective in alleviating anxiety say scientists. The results came from an analysis of 24 studies involving more than 2,000 participants which also showed that combinations of the amino acids L-lysine and L-arginine may be useful anxiety remedies.
A systematic review of research into the use of nutritional supplements for the treatment of anxiety disorders has found strong evidence for the use of extracts of passionflower or kava and combinations of L-lysine and L-arginine. Researchers writing in BioMed Central's open access Nutrition Journal pooled the results of 24 studies involving a total of more than 2000 participants, showing that some nutritional and herbal supplements can be effective, without the risk of serious side effects.
Aeterna Zentaris Inc., today announced that an interim review of a Phase 3 trial of AEZS-130 (macimorelin, SolorelTM), demonstrates the compound may provide a simple, well-tolerated and safe oral diagnostic test for Adult Growth Hormone Deficiency (AGHD). The data was presented earlier today by Beverly M.K. Biller, M.D. of the Harvard Medical School/Massachusetts General Hospital in Boston, at the 5th International Congress of the Growth Hormone Research Society (GRS) and the Insulin-like Growth Factors (IGF) Society in New York City.
Cardium Therapeutics announced that it has gained exclusive access to commercial development rights for certain novel supramacromolecular polymer complexes enabling regulatable and localized topical delivery of nitric oxide for prolonged periods of one to three weeks, to broaden and expand the Company's wound healing and tissue regeneration portfolio.
Researchers in Cedars-Sinai's Department of Psychiatry and Behavioral Neurosciences have reported people who undergo massage experience measureable changes in their body's immune and endocrine response.
Richard Lamb and his post doctoral fellow Virginie Mieulet, in the Faculty of Medicine & Dentistry, may be able to explain why proper nutrition is so vital in fighting infection.
The term "macrophage" conjures images of a hungry white blood cell gobbling invading bacteria. However, macrophages do much more than that. Not only do they act as antimicrobial warriors, they also play critical roles in immune regulation and wound-healing. They can respond to a variety of cellular signals and change their physiology in response to local cues.
Research from the University of Exeter has revealed taking a dietary supplement to boost nitric oxide in the body can significantly boost stamina during high-intensity exercise.
ForeverGreen Worldwide Corp., manufacturer and distributor of all natural whole foods, today announced that it has filed 2010 Q2 financial reports.
Researchers have developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants and a patients' own bone. The stronger connection created by manipulating signals the body's own cells use to encourage growth could allow the implants to last longer.
In 2004, Washington University in St. Lous researcher Jianmin Cui was handed a puzzling clue to the structure of an ion channel his lab had been studying for five years.
