System to help babies avoid brain damage

The same heightened electrical activity that indicates an adult taking a treadmill test isn't getting enough oxygen to his heart is now being measured during labor to see if it can better identify babies in serious distress who need immediate delivery.

Ascorbic acid doesn't seem to help physical exercise performance

Orange juice or other sources of vitamin C (ascorbic acid), may (or may not) benefit you in terms of health and exercise, but contrary to what many people thought previously, ascorbic acid doesn't seem to help physical exercise performance.

Discovery of gene related to p53 called Bnip3L that can also cause cell death

Researchers have known for a decade that the p53 tumor suppressor gene is important for killing cells as they proliferate under low-oxygen conditions inside tumors.

3 or more alcoholic drinks increases risk of ischemic stroke by 45%

A new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and the Harvard School of Public Health (HSPH) has found that heavy drinkers -- men who consume an average of three or more alcoholic beverages per day -- are nearly 45 percent more likely to suffer an ischemic stroke compared with nondrinkers.

Moderate physical exercise can stave off metabolic syndrome in people age 55 to 75

Researchers at Johns Hopkins have determined that in people age 55 to 75, a moderate program of physical exercise can significantly offset the potentially deadly mix of risk factors for heart disease and diabetes known as the metabolic syndrome.

Chemotherapy lowers levels of antioxidants and micronutrients

Children undergoing chemotherapy for acute lymphoblastic leukemia (ALL) have significant changes in their antioxidant and micronutrient status which are related to their treatment outcomes, according to the results of a novel prospective study.

Spinal cord injury and obesity

Researchers at the University of Michigan Health System are looking at how people with spinal cord injury burn calories and how that is affected by their muscle mass and body weight. The goal is to make better recommendations to people with spinal cord injury, but the research will also translate into greater understanding of obesity in the general population as well.

Teen concerns about inhalants and painkiller use

According to the Department of Health and Human Services, results from the annual Monitoring the Future (MTF) survey indicate an almost 7 percent decline of any illicit drug use in the past month by 8th, 10th, and 12th graders combined from 2003 to 2004.

Timing of radiation and antiangiogenic therapy impacts treatment effectiveness

Agents designed to attack blood vessels that feed a growing tumor are effective against tumor growth in laboratory experiments. However, results of early clinical trials with these inhibitors have not yet exhibited the same success observed in animal models.

Model simulates dynamics of heart rhythm disorders

Dutch researcher Kirsten ten Tusscher has developed a model that can simulate the electrical behaviour of the heart during heart rhythm disorders. One of the things her model revealed is that the electrical activity of the heart during a rhythm disorder is much less chaotic than was originally thought.

Babies who do not sleep on their stomachs fail to learn behaviors that may lessen their risk SIDS

Babies who never sleep on their stomachs don't learn behaviors that may lessen their risk of sudden infant death syndrome (SIDS), researchers at Washington University School of Medicine in St. Louis have found. Even so, the researchers caution that infants should always be placed on their backs to sleep.

New advances in sickle cell disease

Excruciating pain episodes, recurrent pneumonias, strokes, severe infections, chronic hemolytic anemia, and secondary pulmonary hypertension are common complications of sickle cell disease, a life-threatening inherited defect in blood that causes normally disc-shaped red blood cells to take on a sickle shape.

Important genetic risk factor for amyotrophic lateral sclerosis

Two Hershey, Pa., researchers were part of a team that has uncovered what may be an important genetic risk factor for amyotrophic lateral sclerosis (ALS).

Children with sickle cell disease who are at risk for a stroke need ongoing blood transfusions to reduce their risk

“This important study shows the value of continuing periodic blood transfusions in preventing the serious and debilitating consequences of stroke,” says NHLBI Acting Director Barbara Alving. “At the same time, there are risks of chronic transfusions and the decision to continue with this treatment must be made on a case-by-case basis.”

Research raises question on shark cartilage use as an anti-cancer treatment

The rising popularity of shark cartilage extract as an anti-cancer treatment is a triumph of marketing and pseudoscience over reason, with a tragic fallout for both sharks and humans, according to a Johns Hopkins biologist writing in the Dec. 1 issue of Cancer Research.

Study focused on patients with chemotherapy-related anemia

Findings from an interim analysis of a new study comparing the hemoglobin response rates of Epoetin alfa and darbepoetin alfa in the treatment of chemotherapy-related anemia were published in the November 15, 2004 issue of the Medical Journal 'Blood' as part of the American Society of Hematology 46th Annual Meeting and Exposition.

Human endogenous retroviruses (HERVs)

Human endogenous retroviruses (HERVs) have been the subject of a great deal of investigation in recent years. It has been established that HERVs cause some genetic diseases and there is strong circumstantial evidence for a link to some types of cancer and autoimmune diseases, but what else do we need to know about these unique organisms?

Citrus fruits offer promise in fighting childhood cancer

Orange juice and cancer don't mix. In fact, the popular citrus drink could become a cocktail to prevent or stop the deadly disease in humans.

Lighter air more than doubles COPD patients’ endurance

It certainly makes sense: COPD sufferers have varying degrees of serious breathing difficulties, which keeps them from almost any kind of exercise, especially in advanced stages. So maybe “lighter than air” air would be easier to breath, reduce shortness of breath and perhaps even allow them to do some exercise with all of its physical and mental benefits.

Salmonella pathogen uses molecular hydrogen to grow and become virulent

New research, headed by microbiologists from the University of Georgia, show for the first time that Salmonella – a widespread and often deadly bacterial pathogen – use molecular hydrogen to grow and become virulent.
