Close connection between gender-based violence and HIV infection

amfAR has released an issue brief demonstrating a close connection between gender-based violence and HIV infection. The New York-based AIDS research foundation is calling for resources to develop, test, and implement behavioral, biomedical, and social interventions to address violence as both a cause and a consequence of HIV infection.

Way now clear for FDA approval of Plan B "morning-after" pill

Now that senators Patty Murray of Washington and Hillary Clinton of New York, have dropped their objections to acting FDA Commissioner Lester Crawford becoming the permanent commissioner, approval for the sale of the Plan B "morning-after" contraceptive without a prescription should be granted with the minimum of delay.

Nebivolol may help control high blood pressure

According to research presented at ISHIB2005, nebivolol was shown to be statistically significantly better than placebo in reducing systolic and diastolic blood pressure among African-American hypertensive patients in a multicenter, randomized, double-blind, placebo-controlled study.

Telephone helps reduce diabetes health disparities and improves health outcomes

In this high-tech world of electronic communications, the older, reliable form of communication via the telephone has proven effective in reaching out to older African-American women with diabetes.

Females showed less of an increase in systolic blood pressure (SBP) than their male counterparts after exercise

Young girls (aged 16-8 years) may have a secret to healthy hearts according to a new study presented at ISHIB2005. Before and after participating in stress-producing activities, male and female teenagers were measured for blood pressure levels. Females showed less of an increase in systolic blood pressure (SBP) than their male counterparts.

Chemical sealant - poloxamer 188 can repair damage to cardiac muscle cell membrane

A common chemical used in the manufacturing and pharmaceutical industries can repair damage to cardiac muscle cell membranes and prevent heart failure in mice with the genetic mutation that causes Duchenne muscular dystrophy, according to scientists at the University of Michigan Medical School.

Ethical guidelines suggested for stem cell research in primates

Before conducting research that involves putting human stem cells into the brains of nonhuman primates such as monkeys or apes, scientists and oversight committees should consider a series of ethical criteria, according to a policy paper released in the July 15 issue of Science.

Genome studies may help target new drugs to fight them

One parasite causes a deadly sleeping sickness in Africa. The second damages the internal organs of millions of Latin Americans. The third causes terrible lesions on the face or limbs of victims from Brazil to India.

Study shows mutation in NOTCH1 gene causes aortic valve disease

By studying five generations of a Dallas family, UT Southwestern Medical Center researchers have discovered that a mutation in a key gene causes aortic valve disease, a common heart birth defect as well as a major contributor to adult heart disease.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

NIPA levels act as switch regulating cell division

Cells control mitosis (cell division) by assembling a biochemical switch to block it or by disassembling the switch to trigger it, according to investigators at St. Jude Children's Research Hospital and the Technical University of Munich.

Oxytocin raises aggression, cuts anxiety during lactation

Maternal aggressive/protective behavior is recognized throughout mammalian species, especially during lactation. When hiking, we warn our kids not to approach bear cubs, or to get between a cub and the mother. While driving and you see a fawn, you know a doe can't be too far away and will run headlong to protect it.

Scientists sequence the genomes of three species of parasites responsible for causing diseases that kill or cripple millions

Howard Hughes Medical Institute (HHMI) scientists who participated in the project say the sequencing of the genomes of the parasitic protozoa that cause Chagas disease, African sleeping sickness, and leishmaniasis, could significantly impact world health. Some of the genes discovered may prove to be good drug and vaccine targets.
