Recent drug use masks cocaine abusers' cognitive impairment

Recent cocaine use may hide some of the cognitive deficits commonly experienced by individuals addicted to cocaine, scientists at the U.S. Department of Energy's Brookhaven National Laboratory report in a study published in the April 2009 issue of Neuropsychopharmacology - a special issue dedicated to cocaine research.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.

New tissue engineering technique may help stem cells generate solid organs

Stem cells can thrive in segments of well-vascularized tissue temporarily removed from laboratory animals, say researchers at the Stanford University School of Medicine.

Instant immunity through chemically programmable vaccination and covalent self-assembly

The experiments, thus far performed only in mice, appear to overcome a major drawback of vaccinations - the lag time of days, or even weeks, that it normally takes for immunity to build against a pathogen.

A new monkey model for HIV

By altering just one gene in HIV-1, scientists have succeeded in infecting pig-tailed macaque monkeys with a human version of the virus that has until now been impossible to study directly in animals.

Chantix may also help people control drinking

A popular smoking cessation drug dramatically reduced the amount a heavy drinker will consume, a new Yale School of Medicine study has found.

Discovery of gene involved in pancreatic cancer

Researchers from the University of Michigan Comprehensive Cancer Center have identified a gene that is overexpressed in 90 percent of pancreatic cancers, the most deadly type of cancer.

Bacteria-killing enzyme cures mice with fatal pneumonia

Before the advent of antibiotics, pneumonia claimed so many lives - and was so feared - that it was called the "captain of the ship of death."

Experimental drug fampridine improves mobility for some MS patients

In MS, the body's immune system attacks myelin, a fatty tissue that wraps and insultates nerve fibers, disrupting the transmission of signals in the central nervous system.

New gene associated with Lou Gehrig's disease

A collaborative research effort spanning nearly a decade between researchers at Massachusetts General Hospital (MGH) and King's College London (KCL) has identified a novel gene for inherited amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease).

Spun-sugar filaments show potential for regenerating nerves

Researchers at Purdue University have developed a technique using spun-sugar filaments to create a scaffold of tiny synthetic tubes that might serve as conduits to regenerate nerves severed in accidents or blood vessels damaged by disease.

Antibody recognition of a highly conserved epitope across influenza viruses

The discovery of the molecule, an antibody known as CR6261, is good news for researchers who hope to design a flu vaccine that would give humans lifelong protection against a majority of influenza viruses.

Scientists develop general-purpose method for detecting trace chemicals

Described in an advance, online publication of the journal Nature Biotechnology on February 22, 2009, the team's general method could be adapted for detecting a wide variety of compounds, including many that are relevant to diagnostic medicine and environmental work.

Lab tests show meropenem and clavulanate combination effective against drug-resistant TB bacteria

WHAT: In a finding that could soon help people infected with untreatable, highly drug-resistant tuberculosis (TB), scientists have shown that two FDA-approved drugs work in tandem to kill laboratory-grown strains of Mycobacterium tuberculosis (Mtb), the bacterium that causes TB.
