How neurotransmitters travel between cells

In studying how neurotransmitters travel between cells - by analysis of events in the dimensions of nanometers - Cornell researchers have discovered that an electrical current thought to be present during that process does not, in fact, exist.

New generation of implanted heart-assisting pumps help patients survive, regain function til transplant

A new generation of implanted heart-assisting pump does very well at helping severely ill heart-failure patients survive, and thrive, until they receive a heart transplant, a new study shows.

Autophagy-induced signals are essential for normal development

A cannibalistic process called autophagy spurs dying embryonic stem cells to send "eat me" and "come get me" signals to have their corpses purged, a last gasp that paves the way for normal mammalian development, UT Southwestern Medical Center researchers have found.

Gamma globulin effective treatment for pinkeye

Gamma globulin, a type of antibody isolated from blood samples that used to be routinely given to health care workers and international travelers to protect them from infectious diseases, is a highly effective treatment for pinkeye with little apparent toxicity, according to a study by researchers at the University of Pittsburgh School of Medicine.

Tympanic membrane perforation may indicate brain injury

Physicians treating patients who have suffered tympanic membrane perforation as a result of blast should also look for signs of comcomitant brain or neurologic injury, according to a study published in the August 23 edition of the New England Journal of Medicine .

Scientists investigate initial molecular mechanism that triggers neuronal firing

Carnegie Mellon University chemists have solved a decade-long molecular mystery that could eventually help scientists develop drug therapies to treat a variety of disorders, including epilepsy and Alzheimer's disease.

Cell-based sensor for analysis of EGFR biomarker expression in oral cancer

Using a microfluidic device designed to capture and enrich cells from biological samples, a research team at The University of Texas at Austin has developed a test that can detect an important early marker for oral squamous cell carcinoma, which accounts for more than 90 percent of oral cancers. Oral cancer is the sixth most common cancer worldwide and is difficult to detect early enough to treat successfully.

We need to treat cancer like an infectious disease

Among the many medical miracles produced by science over the years, vaccines and antibiotics have undoubtedly saved the most lives.

Scientists discover new mechanism for viral replication

Researchers at the University of Pennsylvania School of Medicine have identified a new strategy that Kaposi's Sarcoma Associated Herpesvirus (KSHV) uses to dupe infected cells into replicating its viral genome.

First biomarker discovered that predicts prostate cancer outcome

Mayo Clinic researchers have identified the first immune molecule that appears to play a role in prostate cancer development and in predicting cancer recurrence and progression after surgery.

New findings on cholesterol metabolism

A team of researchers investigating cholesterol and lipid transport has performed experiments that cast serious doubt on the dominant hypothesis of how the body rids its cells of "bad" cholesterol (LDL) and increases "good" cholesterol (HDL).

Direct pathways between extracellular material and cell nuclei discovered

A team of Brooklyn College researchers has shattered a long-held belief that no direct pathway exists between material outside of a cell and the cell nucleus.

Scientists find mechanisms controlling metastasis of breast cancer cells

When cancer cells dissociate from the original tumor and migrate via the blood stream to colonize distant organs, is the main cause of cancer death.

Potential new ways to prevent smoking-related cellular damage

In the current issue of PLoS One, researchers show how a poorly understood and previously unsuspected mechanism may be the key to understanding how life-style associated forms of oxidative stress, such as exposure to cigarette smoke, damage cells in the lungs.

How cells change the pace of their steps

Scientists at UC San Diego have discovered how cells of higher organisms change the speed at which they move, a basic biological discovery that may help researchers devise ways to prevent cancer cells from spreading throughout the body.

Phase II study of TroVax vaccine in patients with metastatic colorectal cancer

A therapeutic cancer vaccine has shown effectiveness when given alongside chemotherapy to patients with metastatic colorectal cancer in a phase II trial, according to researchers at Oxford BioMedica (UK) Ltd.

Cell injury caused by brushing may help keep gums healthy

One way regular brushing may help keep gums firm and pink is, paradoxically, by tearing open cells, researchers have found.

Drugs designed to disable enzyme TOPK could have anti-cancer benefits

Working with human colorectal cancer cells, a University of Minnesota team, led by cancer biologists Zigang Dong and Ann Bode, has found the potential culprit among a network of enzymes that relay signals inside cells to regulate such functions as cell growth, cancer development and programmed cell death.

Imaging technique accurate in aneurysm detection and therapy planning

Multidetector computed tomography (MDCT) angiography is highly accurate in depicting intracranial aneurysms, according to a study published in the August issue of Radiology.
