Vitamin C Raises Risk Of Kidney Stones
Date: Feb-06-2013Men who consume high levels of vitamin C are at twice the risk of kidney stones than men who do not. The new finding does not strongly establish that vitamin C is responsible for the occurrence of kidney stones, however it may make us wonder whether large amounts of vitamin C are harmful to the body. Kidney stones are tiny masses of crystals that can painfully obstruct the urinary tract. Signs and symptoms of a kidney stone include: severe pain from the flank to groin or to the genital area and inner thigh...
The Secret About Cosmetic Surgery That Doctors Are Hiding
Date: Feb-06-2013A secret about cosmetic surgery exists that several physicians are hiding from their patients. The truth is many doctors performing cosmetic surgery in the USA are not actually cosmetic surgeons, a claim made by a growing number of board certified cosmetic surgeons around the country. Currently, there are doctors who specialize in other areas who have little to no experience in plastic surgery who are performing these procedures...
Study Raises Questions About Dietary Fats And Heart Disease Guidance
Date: Feb-06-2013New analysis of missing data casts doubt on diet-heart advice Dietary advice about fats and the risk of heart disease is called into question on bmj.com today as a clinical trial shows that replacing saturated animal fats with omega-6 polyunsaturated vegetable fats is linked to an increased risk of death among patients with heart disease. The researchers say their findings could have important implications for worldwide dietary recommendations...
Unraveling The Brain's Vision Secrets
Date: Feb-06-2013A new study led by scientists at the Universities of York and Bradford has identified the two areas of the brain responsible for our perception of orientation and shape. Using sophisticated imaging equipment at York Neuroimaging Centre (YNiC), the research found that the two neighbouring areas of the cortex -- each about the size of a 5p coin and known as human visual field maps -- process the different types of visual information independently...
Father's Obesity Influences Child's Cancer Risk
Date: Feb-06-2013Obese men are more likely to father children who go on to develop cancer, compared to men of normal weight, researchers from Duke Unviersity Hospital reported in BMC Medicine. Previous studies showed that a mother's diet and weight might impact a child's health - even before he/she is born. Hypomethylation of the gene coding for IGF2 (Insulin-like growth factor 2) in infants increases their risk of developing cancer when they are older...
Energy Drinks' Health Hazards For Adolescents
Date: Feb-06-2013Many energy drinks have ingredients which can have a harmful effect on adolescent health, especially when mixed with alcohol, says a news report published in Pediatrics in Review. The article - "Energy Drinks: What Teenagers (and Their Doctors) Should Know," - summarizes recent evidence regarding the content, benefits and risks of energy drinks which are consumed by teenagers. Energy drinks are beverages with caffeine added to them. They are advertised as a means to enhance performance, boost the immune system, or create a "buzz"...
Growth Of Gleevec-Resistant Gastrointestinal Tumors Hindered By Antibody In Lab Tests
Date: Feb-06-2013An antibody that binds to a molecule on the surface of a rare but deadly tumor of the gastrointestinal tract inhibits the growth of the cancer cells in mice, according to researchers at the Stanford University School of Medicine. The effect remains even when the cancer cells have become resistant to other treatments, and the findings may one day provide a glimmer of hope for people with the cancer, known as gastrointestinal stromal tumor, or GIST. The scientists hope to move into human clinical trials of the antibody within two years...
Stem Cell Regeneration After Radiation Damage Aided By Growth Factor
Date: Feb-06-2013Epidermal growth factor has been found to speed the recovery of blood-making stem cells after exposure to radiation, according to Duke Medicine researchers. The finding could open new options for treating cancer patients and victims of dirty bombs or nuclear disasters. Reported in the journal Nature Medicine, the researchers explored what had first appeared to be an anomaly among certain genetically modified mice with an abundance of epidermal growth factor in their bone marrow. The mice were protected from radiation damage, and the researchers questioned how this occurred...
Palliative Care And Patient Choices In Advance Care Directives
Date: Feb-06-2013Advance care directives allow patients to provide instructions about their preferences for the care they would like to receive if they develop an illness or a life-threatening injury and lose the capacity to make decisions for themselves...
Myeloma, Lupus, Rheumatoid Arthritis Patients May One Day Benefit From Research On Immune Cell 'Survival' Gene
Date: Feb-06-2013Scientists have identified the gene essential for survival of antibody-producing cells, a finding that could lead to better treatments for diseases where these cells are out of control, such as myeloma and chronic immune disorders. The discovery that a gene called Mcl-1 is critical for keeping this vital immune cell population alive was made by researchers at Melbourne's Walter and Eliza Hall Institute. Associate Professor David Tarlinton, Dr Victor Peperzak and Dr Ingela Vikstrom from the institute's Immunology division led the research, which was published in Nature Immunology...
