New drug targets for multiple myeloma

Research investigators have identified molecular changes in multiple myeloma cells that activate an important biological pathway associated with cell growth and survival, thereby revealing potential new targets for drugs to treat this cancer.

High-intensity focused ultrasound may alerts the immune system to cancer

An intense form of ultrasound that shakes a tumor until its cells start to leak can trigger an alarm that enlists immune defenses against the cancerous invasion, according to a study led by researchers at Duke University's Pratt School of Engineering.

FDA approves maraviroc, an antiretroviral drug for use in adult HIV patients.

The U.S. Food and Drug Administration (FDA) has approved maraviroc, an antiretroviral drug for use in adult HIV patients. Maraviroc, sold under the trade name Selzentry, is the first in a new class of drugs designed to slow the advancement of HIV and received priority review by the FDA.

How the brain produces fever responses during infections

With the finding that fever is produced by the action of a hormone on a specific site in the brain, scientists have answered a key question as to how this adaptive function helps to protect the body during bacterial infection and other types of illness.

First case of successful ovarian tissue transplantation between two, nonidentical sisters

A woman, whose ovaries had failed due to damage caused by chemotherapy and radiotherapy, has received a successful ovarian transplant from her genetically non-identical sister.

Key signs of appendicitis

A 5-year-old with abdominal pain, nausea and fever may have appendicitis or any of a number of other problems.

Jump in cancer-related clots

Blood clots are increasingly common in cancer patients, but University of Rochester Medical Center researchers have created a novel risk model that can predict, with 98 percent certainty, which patients will not get a blood clot.

Biological markers of narcolepsy

The first report to identify the biological markers of narcolepsy using gene expression in white blood cells finds that the MX2 gene, which is relevant to the immune system, is significantly less expressed in narcoleptics compared with normal subjects.

Woman has successful ovarian transplant from her sister

A woman whose ovaries were damaged by chemotherapy and radiotherapy, has received a successful ovarian transplant from her sister.

New target for Hodgkin lymphoma

Dana-Farber Cancer Institute scientists have identified a protein that prevents the body's immune system from recognizing and attacking Hodgkin lymphoma cells.

Tonsil epithelial factors may influence oropharyngeal HIV transmission

Current research demonstrates that the tonsils may possess the necessary factors to act as a transmission site for the spread of HIV.

White blood cell booster may help cancer patients avoid deadly complications

Cancer patients who receive a drug that stimulates the growth of infection-fighting white blood cells may be significantly less likely to die from a chemotherapy-related complication characterized by fever and low white blood cell levels, according to a multi-institutional study led by researchers from the University of Rochester School of Medicine and Dentistry and the Duke University Comprehensive Cancer Center.

New combo treatment for chronic lymphocytic leukaemia increases survival

The combination treatment of fludarabine plus cyclophosphamide for chronic lymphocytic leukaemia (CLL) greatly increases progression-free survival and response rates, compared with single treatment with either fludarabine or chlorambucil alone.

Three gene variants discovered that help fight HIV

An international team of researchers has identified three gene variants in the DNA of 486 people infected with HIV that appear to have helped some of the patients fight off the virus and delay the onset of full-blown AIDS.

Key mechanism to emergence of deadly strep bacteria discovered

The incidence of serious strep infections has risen dramatically in the last three decades, and this increase is largely attributed to the spread around the globe of a single strain of strep known as the invasive M1T1 clone.

Scientists discover human genes hover between "on"and "off" in any given cell

Biologists have long thought that a simple on/off switch controls most genes in human cells.

Wilmot Cancer Center studies new chemo pill for lymphoma

Doctors at the University of Rochester's James P. Wilmot Cancer Center are first in the world to study a new, targeted agent that zeroes-in on B-cell lymphomas. The new twice-a-day pill offers patients with recurrent disease another choice as their options grow thin.

White blood cells are picky about sugar

Biology textbooks are blunt - neutrophils are mindless killers. These white blood cells patrol the body and guard against infection by bacteria and fungi, identifying and destroying any invaders that cross their path. But new evidence, which may lead to better drugs to fight deadly pathogens, indicates that neutrophils might actually distinguish among their targets.
