Step toward understanding the mystery surrounding drug resistance

The cellular "pumps" associated with multi-drug resistance in bacteria may also be involved in exporting signals responsible for cell-cell communication, a process known as quorum sensing, said researchers from Baylor College of Medicine in a report that appears online in the Proceedings of the National Academy of Sciences.

Hormone discovered in bird brains also plays major role in mammalian reproductive system

University of California, Berkeley, researchers have discovered a new actor in the mammalian reproductive system, a hormone that fills a role long suspected, but until now undetected.

HIV subtype is a better predictor than viral load for determining rapid death from AIDS

Traditional testing standards help monitor the progression of an HIV infection to AIDS by keeping track of viral load, using a scale in which less than 50 viral particles per cubic milliliter of blood is considered suppressed disease and a viral load of more than 75,000 particles per cubic milliliter of blood means that the disease will progress more rapidly.

Mad cow proteins also maintain stem cells

What do mad cow disease and stem cell research have in common? Whitehead Institute scientists have found that the same protein that causes neurodegenerative conditions such as bovine spongiform encephalopathy (mad cow disease) is also important for helping certain adult stem cells maintain themselves.

Infant transplant patients resist infections that kill adult AIDS patients - possible new treatments for debilitating diseases

Investigators have discovered that some type of protective system goes into action in some cases when a baby's immune system is deficient.

Two-drug treatment could help asthma and chronic bronchitis sufferers

Current treatments for asthma and chronic bronchitis aren't able to address the ultimate source of the problem--they can only alleviate symptoms.

PET imaging has the potential to improve cancer care management

A limitation of current cancer care is the difficulty of quickly assessing how well a therapy is working. However, expanding the use of existing positron emission tomography (PET) technology can provide early and accurate assessment of a tumor's response to a particular therapy allowing physicians to better tailor a patient's treatment

Link between dementia and cancer

By expressing a protein associated with Alzheimer's disease in the brain of the fruit fly, researchers have demonstrated an intriguing link between neuronal death and proteins previously associated with cancer.

New insight into one of the fundamental features of evolution

By experimentally promoting rapid, small-scale evolution within a lab population of yeast, researchers have shed light on the kinds of genetic changes that may underlie the emergence of new species.

Abraham Lincoln may have suffered from movement disorder

Researchers at Johns Hopkins and the University of Minnesota have discovered a gene mutation in the descendants of Abraham Lincoln's grandparents that suggests the Civil War president himself might have also suffered from a disease that destroys nerve cells in the cerebellum-- the part of the brain that controls movement.

DNA end caps may lead to cancer treatments

The two ends of human DNA have different structures that are treated differently as a cell divides, UT Southwestern Medical Center researchers have found in a study that could help lead to cancer therapies.

Myosin VI can act as molecular transporter

Myosin VI has been thought to be a monomer, but Park et al. show that full-length myosin VI can be a dimer, and can walk processively on actin. By increasing the concentration, a greater and greater fraction dimerizes in vitro, and walks processively on actin.

Research sheds light on origins of "junk" DNA

In experiments with transgenic mice, University of Pennsylvania School of Medicine researchers discovered the remaining steps in the complicated process of how the largest class of jumping genes replicates and inserts themselves within the human genome.

Engineered heart tissue offers insights into irregular heartbeats

Engineers who have induced heart cells in culture to mimic the properties of the heart have used the tissue to gain new insight into the mechanisms that spawn irregular heart rhythms.

Source of crucial immune cell in the skin discovered - may lead to tumor immunotherapy

Mount Sinai School of Medicine researchers have identified the precursors of cells in the skin that are part of the first line of defense against invading pathogens. The study appears on Nature Immunology's website.

Cell phones help reduce error rate in hospital care

Using mobile telephones in hospitals reduces the error rate in medical care because of more timely communication and rarely causes electronic magnetic interference, Yale School of Medicine researchers report this month.

Intracellular observation of RNA metabolism will help identify disease-associated RNAs

For the first time, researchers can now peer inside intact cells to not only identify RNA-binding proteins, but also observe-in real-time-the intricate activities of these special molecules that make them key players in managing some of the cell's most basic functions.

Alternative method to produce heparin

Researchers at Rensselaer Polytechnic Institute and University of North Carolina at Chapel Hill have discovered an alternative way to produce heparin, a drug commonly used to stop or prevent blood from clotting.

Study finds brain changes begin gradually in 'middle age'

A study looking at brain function in young, middle-aged and older adults has identified changes in brain activity that begin gradually in middle age - and which may explain why older adults find it difficult to concentrate in busy environments and filter out irrelevant information.

7 Feb 2006

Link between high levels of a protein HtrA1 and preeclampsia

Mayo Clinic researchers have found an association between abnormally high levels of a protein named HtrA1 and preeclampsia, a sudden and dangerous rise in blood pressure that can result in premature delivery, disability or death for mother and fetus.
