A gene's first 'kiss' sets off that affair known as puberty
Puberty, that awkward phase when boys and girls are primed for their sexual reproductive years as men and women, appears to be triggered by the brain's own version of "It takes two to tango," whereby a signal literally gets turned on by a molecule that is produced by a gene aptly named KiSS-1. The couple ?a biochemical equivalent to Adam and Eve ?makes its sudden appearance in a region of...Deficient DNA Repair Capacity Associated With Increased Risk Of Breast Cancer
Deficiencies in the ability of cells to repair damaged DNA are associated with an increased risk of breast cancer, according to a new study in the January 19 issue of the Journal of the National Cancer Institute. is the system of defenses designed to protect the integrity of the genome. Studies have suggested that deficiency...Scientists discover the cellular roots of graying hair
Few things about growing older are asinevitable and obvious as “going gray,?yet scientists have been unableto explain the precise cause of this usually unwelcome transformation.In a report posted today on the Web site of the journal Science,researchers from Dana-Farber Cancer Institute and Children’s HospitalBoston say they have found the cellular cause of graying hair whileinvestigating th...DNA Recombination and Repair—A New Twist to RecA Function
Molecular motors harness the energy of ATP (or GTP, a related energy currency) and transform it into mechanical force. Well-known examples of motors include myosin and dynein, proteins that use ATP to ferry intracellular cargo along fibers made of actin or tubulin proteins. The ATP-dependent assembly of actin or tubulin fibers itself can work as a motor: for instance, the march of white blood cel...New studies suggest airborne SARS transmission is possible
Two new studies present evidence that the virus causing severe acute respiratory syndrome (SARS) may spread through the air, not just through direct contact with contaminated water droplets as previous research had shown. SARS coronavirus was detected in the air in a patient's room during the 2003 outbreak in Toronto, according to a new study published in The Journal of Infectious Diseases...Rat Hair Follicle Stem Cell Culture from Celprogen

VaniqaT is a prescription drug which was approved by the FDA in the United States on July 31, 2000 for treating excessive facial hair in women, which is often part of hirsutism. It may be a welcome alternative for women for whom this problem is considered serious enough to warrant tweezing, waxing, or shaving at least once a week for hair removal. Vaniqa is actually not a b...Pesticide impairs male reproductive function
According to the May issue of the journal Epidemiology, high levels of DDT found in some Mexican workers suggest that pesticide can impair male reproductive function. The human body metabolises DDT to DDE. An international team of researchers took blood samples from 24 men aged 16 to 28 who had not been exposed to DDT in their work. In these men the high DDE levels correlated to low leve...Air pollution affects the heart
Air pollution is known for its adverse effects on the heart among the young and old.There are tiny pollutant particles called PM10s, which have a diameter of less than ten micrometres. These can cause problems with lung and heart function, by entering the circulation, especially in people with pre-existing disease. According to a new study by researchers at Harvard University now reve...Sense of smell impaired in alcoholics
A study published in the March issue of the journal Alcoholism: Clinical and Experimental Research reported that alcohol abuse can dampen the sense of smell. Researchers from the University Clinics of Innsbruck studied the sense of smell in 30 alcoholics and 30 healthy people who were matched for age, gender and smoking status. They used "Sniffin' Sticks", which are pen-like devices that...Omega-3 fatty acids impair immunity
Taking large amounts of omega-3 fatty acids may be unwise for those with weakened immunity.Researchers at the University of Missouri, Columbia, have been studying omega-3s for many years now and know that one of their effects is to damp down inflammation. That's why fish oils - rich in omega-3s - often benefit those with arthritis, a painful inflammatory condition of the joints. Yet the i...Moist Air Humidifying Chambers
