High Hep C levels found among young low-income women
UCSF researchers have found that low-income women between the ages of 18 and 29 in San Francisco are infected with hepatitis C virus (HCV) at a level almost two and a half times higher than the HCV infection rate for the general population in the United States.

Leptin linked to obesity and blood clots
High levels of leptin, a hormone produced by fat cells in the body, could explain why obese people develop dangerous blood clots -- which can cause heart attacks and strokes - more often than people who are not overweight.

UCSD high-speed internet enabled bus
Engineers at UCSD have unveiled the world's first bus that enables its passengers to access the Internet and download files at a peak speed of 2.4 Megabits per second--even while the bus is moving.

Genetic variants put some patients at risk for particular drug reactions
This is one of the first studies to show an association between genetic variants and the risk of a serious adverse drug reaction.

Shuji Nakamura, materials professor and director of the Center for Solid State Lighting and Displays at the University of California at Santa Barbara, has been awarded an ERATO grant worth 1.7 billion yen (approximately $16 million) by an agency of the Japanese government.

UCSD structural engineers design weld-free steel frame
Researchers at the University of California, San Diego's (UCSD) Jacobs School of Engineering have applied post-tensioning, a technique commonly used in the construction of concrete buildings and bridges, to create a new class of weld-free steel-framed structures.

Gene alteration spurs growth of colon cancer
HHMI researchers have discovered a novel gene alteration that causes an abnormal cellular

Hormone replacement therapy may be associated with increased ovarian cancer risk
Women who have taken some forms of hormone replacement therapy may be at an increased risk of developing ovarian cancer, a new study suggests.

Report shows decline in youth smoking, but work remains
Adolescent smoking rates increased through much of the 1990s, but a new report released today by the National Cancer Institute (NCI) shows there has been a promising decline over the past few years.

Other highlights in the April 3 issue of JNCI
Other highlights include studies that identify a tumor suppressor gene for prostate cancer and a marker of progression of colon cancer, a study that looks at the effects of depsipeptide in lung cancer cells, and a study that looks at the cancer-specific expression of the survivin promoter.

Statins may prevent damage by Alzheimer's disease protein, USF study finds
Commonly-used cholesterol-lowering drugs, known as statins, block damage by an Alzheimer's-associated protein in neurons and blood vessels, a study by University of South Florida researchers found.

U-M scientists find new genetic marker for prostate cancer
Using the power of advanced DNA microarray technology, scientists at the University of Michigan Medical School have identified a gene that triggers production of large amounts of a specific protein in cancerous prostate cells.

Chemical messenger controls bone growth in embryos, study finds
Scientists at Washington University School of Medicine in St. Louis have for the first time identified a chemical messenger that regulates bone development in the growing embryo.

APS announces its 2002 Young Investigators Awards
APS names five Young Investigators in the field of physiology to receive awards totalling almost $90,000.

Novel gene therapy approach in 1st human trials
Researchers at The Research Institute of University Hospitals of Cleveland performed a gene transfer today (April 2) in the nose of a 33-year-old cystic fibrosis patient.

Study links gene to success of a treatment for high blood pressure
Someday, people taking medications for high blood pressure may undergo genetic screening tests that help identify which drug therapies are best for them.

Engineers make strong, environmentally friendly plastic foams
Engineers have found a way to make dense plastic foam that may replace solid plastic in the future.

HFES 46th Annual Meeting changes venue and dates
The Human Factors and Ergonomics Society 46th Annual Meeting, originally scheduled for September 23-27 in Pittsburgh, has been changed.

Robert Cabanes- Travail, famille, mondialisation
Brazil has experienced sustained economic growth since the 1950s. The São Paulo conurbation, the industrial heartland of this emerging country, has seen its population rise from 2 million to 20 million.

Low socioeconomic status may influence quality of breast cancer treatment
Socioeconomic status, rather than race, may determine quality of breast cancer treatment and outcome, a new study suggests.

NASA pinpoints where rain comes from and where it goes
A new NASA computer model can now tell exactly where in the world rain or snow that provides local water originated.

Launching of the AMMA (1) project, an international research programme on the West African monsoon
Focused on the West African monsoon, the AMMA programme (African Monsoon Multidisciplinary Analysis) has been launched.

Research: Early unsolicited sexual encounters lead to life of crime
People who experienced unsolicited sexual touching before puberty stand a greater chance of ending up serving jail time as teen-agers or adults, according to research conducted at the University of Houston.

Primate bushmeat : Populations exposed to simian immunodeficiency viruses
Humans are exposed to a wide range of simian immunodeficiency viruses (SIV) by hunting and eating primate bushmeat.

Cellular link between sleep apnea and atherosclerosis found
Sleep apnea, a disorder characterized by the temporary cessation of breathing during sleep, displays the same cellular and biochemical changes that are found in atherosclerosis, a disease in which the walls of the arteries thicken, harden, and lose elasticity, resulting in impaired blood circulation.
