Almost half of all medicines globally are used irrationally according to WHO

Almost half of all medicines globally are used irrationally. This, say medicines experts at the World Health Organization (WHO), can have severe consequences: adverse drug reactions, drug resistance, protracted illness and even death. In addition, the financial cost incurred by individuals and governments due to irrational use is unnecessary and often extremely high, particularly in developing countries where patients often pay for medicines out of pocket.

A common antibiotic used to treat arthritis and acne shows promise for limiting the severity of spinal cord and brain injuries

When a fall, car crash, bullet, or knife crushes or cuts a spinal cord, the injury does not stop there. Rather, tissues continue to discharge toxic chemicals for hours, even days and weeks. These chemicals kill and disable nerve cells some distance away from the core injury, compounding the damage and making rehabilitation more difficult or impossible.

Researchers turn off individual human genes to study their function

Researchers have produced vast libraries of short segments of ribonucleic acid (RNA) that can be used to turn off individual human and mouse genes to study their function. The libraries will be made widely available to laboratories studying human biology and disease. The researchers are optimistic that the libraries will become a powerful research tool for gene analysis and discovery.

Discovery of new gene sheds light on human brain development

With the identification of the gene responsible for a newly recognized type of mental retardation, researchers at Beth Israel Deaconess Medical Center (BIDMC) have also discovered what appears to be the key target in the evolution of the frontal lobes of the brain's cerebral cortex. The findings offer a key insight into the complex puzzle of human brain development - and the evolution of human behavior.

Study shows Levitra enhances patients' self-esteem by improving erections

The first clinical study to evaluate LEVITRA™ (vardenafil HCl) in men with mild Major Depressive Disorder (MDD) and erectile dysfunction (ED) showed LEVITRA produced statistically significant improvements over baseline in all measures of erectile function (EF) and depression/self-esteem. In the study, men taking Levitra were nearly three times more likely to report improved erections than men taking placebo.

Alcohol Consumption Decreases Risk of Heart Disease in Men

Cardiovascular disease, including heart disease and stroke, is the leading cause of death in the United States. To help combat this epidemic, studies throughout the United States pinpoint dietary guidelines to reduce risk including a recent release from the American Heart Association which stated that hypertensive patients should avoid alcoholic beverages.

New pill for post-traumatic stress disorder

Every day, people suffer traumatic experiences that scar their minds. Combat, rape, bombings, burns, beatings, and horrific car accidents haunt them with memories impossible to suppress. Such day- and nightmares are part of a problem known as post-traumatic stress disorder, or PTSD.

Government, industry, and academia focus on obesity

Amid shifting scientific data on nutrition and obesity, experts from government, industry, and academia converged on Harvard Medical School last week to discuss obesity's causes and how to craft a coherent public nutritional message.

Scientists identify blood development gene which may aid the fight against cancer and leukemia

Researchers at Harvard-affiliated Dana-Farber Cancer Institute have pinpointed a crucial gene on which the normal development of the body's entire blood system depends. If the gene is absent, even the most basic blood stem cells cannot be generated. In a mutated form, this gene can cause a rare and devastating form of leukemia.

Stem cells and female reproduction: lessons from an unexpected source

Baltimore, MD. The recent findings reported in Nature (March 11, 2004) by Jonathon Tilly’s group at Harvard Medical School, show that female mice produce stem cells that give rise to eggs. This result overturns previous notions about mammalian reproduction, which held that females are born with all the eggs that they will ever have and that the decline in egg quality that occurs after a certain age is due to an extended aging process. What mammalian research has not been able to address at this point, however, is how these stem cells operate, what prompts them to develop into eggs, and why they are eventually lost. To answer these questions we must turn to our cousin the fruitfly.
