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 First Hospital of Peking University, China-Research, has shown that electroacupuncture at Pericardium Meridian Point 6 (PC6 or Nei Guan - Pericardium Meridian) may decrease the frequency of transient lower esophageal sphincter relaxation (TLESR), which is the main mechanism underlying gastroesophageal reflux disease (GERD).
Peter K. Gregersen, MD, stares at x-rays of hands, searching out the telltale signs of inflamed joints and wrists from his research subjects with rheumatoid arthritis. With these clinical features at his side, he turns to the basic building blocks of life , the human genome , to figure out what makes these people susceptible to the disabling inflammatory condition.
Research by scientists at UCL (University College London) has clearly demonstrated for the first time the structure and function of a gene crucial to the regulation of blood pressure. The discovery could be important in the search for new treatments for illnesses such as heart disease, the UK's biggest killer.
A collaborative, multidisciplinary team of researchers has created nanoparticles that act much like a developing clot to target tumors.
In the first experiment of its kind, investigators at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR), based at Stanford University, have shown that single-walled carbon nanotubes (SWCNTs) wrapped in poly(ethylene glycol), or PEG, can successfully target tumors in living animals.
What makes dancers different than the rest of us? Genetic variants, says a researcher at the Hebrew University of Jerusalem.
Researchers say that a diet rich in vegetables rather than meat can help to reduce blood pressure, and the more plant protein consumed the better.
Use of the amino acid supplement L-arginine following a heart attack does not improve certain cardiac functions and measurements and may be associated with an increased risk of death, according to a study in the January 4 issue of JAMA: The Journal of the American Medical Association.
When DNA damage is present, p53 stops cell division and gives the cell enough time to repair it. If the damage is irreparable, the protein sets off programmed cell death and protects the cells from degeneration.
A new study led by a researcher at Children's Hospital & Research Center at Oakland is the first to find that an amino acid deficiency in sickle cell disease is the result of hemolysis, a process where red blood cells rupture and release their contents into the blood stream. Low availability of the amino acid arginine is associated with lung disease and death in adult sickle cell patients.
Two infant boys whose bodies were overloaded with excess fluid have led UCSF pediatricians to the discovery of a new genetic disease. In the process, they have discovered a rare type of mutation where different substitutions in a single amino acid cause two different, opposite genetic disorders.
By intensely and systematically comparing the human X chromosome to genetic information from chimpanzees, rats and mice, a team of scientists from the United States and India has uncovered dozens of new genes, many of which are located in regions of the chromosome already tied to disease.
For children with Batten disease and their families, the cruelty of the disease, which robs children of their sight, their cognitive faculties and finally their lives, is made worse by the hunt for a doctor experienced at recognizing and treating patients.
A piece of the topical puzzle of how estrogen goes from protecting women from heart disease to apparently increasing their risk later in life may have been found.
A team of researchers at The Scripps Research Institute has reconstructed the "fossil record" of the immune systems of a group of human cancer patients to investigate if they had ever produced antibodies against their disease.
While a few weeks of regular use of albuterol improved overall asthma control in individuals with one form of the gene, stopping all use of albuterol eventually improved asthma control in those with another form of the gene. Albuterol is the most commonly used drug for relief of acute asthma symptoms, or “attacks.”
Isolated soy protein added to the diets of 14 men, all military veterans under treatment for advanced stages of type 2 diabetes, significantly lowered unwanted proteins in their urine and slightly raised desired HDL cholesterol levels in their blood, researchers say.
Moderate exercise in conjunction with common dietary supplements significantly reduce the risk of atherosclerosis because, combined, they boost the body’s production of nitric oxide, which protects against a variety of cardio-vascular disorders, a new UCLA study led by 1998 Nobel Laureate in medicine Louis J. Ignarro shows.
A quick new technique able to identify genes that evolve rapidly as well as those that change slowly already has pinpointed new targets for researchers developing drugs against tuberculosis and malaria, and it could do the same for other infectious diseases, according to a paper in this week's Nature.
Adenoidectomy and tonsillectomy (adenotonsillectomy) remain two of the most commonly performed surgeries in the United States. For the most part, these procedures are safe and effective; however, risk of post-operative bleeding remains a concern.
