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.
A new chemical imaging technique could one day help in the fight against atherosclerosis, suggests research published in the August 2009 edition of the Journal of the Royal Society Interface.
Recent genetic studies have revealed several new sites of genes that are risk factors for developing rheumatoid arthritis (RA).
Music is social communication between individuals - humming of lullabies attach infant to parent and singing or playing music adds croup cohesion. The neurobiology of music perception and production is likely to be related to the pathways affecting intrinsic attachment behavior, suggests a resent Finnish study. The study gives new information about genetic background of musical aptitude.
ARCA biopharma, Inc. has announced that a comparative analysis of primary endpoint data from four beta blocker trials was presented at the American College of Cardiology 58th Annual Scientific Session being held March 29-31, 2009.
Too little activity by gene regulators called PPARs appears to be a major player in the irreversible lung damage that can occur in children with heart defects, researchers say.
A Texas AgriLife Research scientist and fellow researchers have discovered that arginine, an amino acid, reduces fat mass in diet-induced obese rats and could help fight human obesity.
The National Association of County and City Health Officials (NACCHO) has announced a donation of up to one million doses of FluMist (Influenza Virus Vaccine Live, Intranasal) by MedImmune in a partnership aimed at increasing influenza awareness and vaccinations in underserved communities and populations.
A traditional Mediterranean diet with an additional daily serving of mixed nuts appears to be useful for managing some metabolic abnormalities in older adults at high risk for heart disease, according to a report in the December 8/22 issue of Archives of Internal Medicine.
Identifying malnutrition before surgery in massive weight loss patients seeking body contouring will significantly decrease surgical complications, accelerate wound healing, improve scar quality and boost patient energy levels, according to a study in the December issue of Plastic and Reconstructive Surgery ®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
UC Davis Cancer Center researchers have discovered a metabolic deficiency in pancreatic cancer cells that can be used to slow the progress of the deadliest of all cancers.
St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide.
St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide. The researchers found that the microbes block nitric oxide production by subverting the biochemical machinery used by immune cells called macrophages to produce the chemical.
Many drugs once considered Charles Atlases of the pharmaceutical realm have been reduced to the therapeutic equivalent of 97-pound weaklings as the diseases they once dispatched with ease have developed resistance to them.
Medical imaging represents one of the most used and useful procedures in the oncologist's diagnostic toolkit, even though each of the most useful techniques-magnetic resonance imaging (MRI), computerized tomography x-ray imaging (CT), and positron emission tomography (PET) scanning-has its own set of limitations.
Hopes languished last September when a promising candidate HIV vaccine failed to work. Despite this setback, many researchers still believe immunization is possible, and a new study suggests they're correct-at least at the cellular level.
Australian authorities have issued a warning regarding a drug sometimes used to treat primary nocturnal enuresis (bed-wetting) in children.
A cold slice of watermelon has long been a Fourth of July holiday staple. But according to recent studies, the juicy fruit may be better suited for Valentine's Day.
Scientists have known for more than a decade that a protein associated with the HIV virus is good at crossing cell membranes, but they didn't know how it worked.
A new study led by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) reports on a novel mechanism that can enhance the function of a protein that is frequently impaired in patients with acute forms of leukemia.
Eating right is an ingredient to a healthy lifestyle – a lifestyle that can help reduce cancer.
