Researcher discovers how West Nile virus breaks through the tough blood-brain barrier to CNS

Mosquitoes are buzzing once again, and with that comes the threat of West Nile virus. Tom Hobman, a researcher with the Li Ka Shing Institute of Virology in the Faculty of Medicine & Dentistry, is making every effort to put an end to this potentially serious infection.

Epigenetic changes due to methylation play a key role in altering genes in RA

It's not just our DNA that makes us susceptible to disease and influences its impact and outcome. Scientists are beginning to realize more and more that important changes in genes that are unrelated to changes in the DNA sequence itself - a field of study known as epigenetics - are equally influential.

Investigators identify cell replacement/tissue repair potential in adult bone marrow stem cells

Researchers from the University of Maryland School of Maryland report promising results from using adult stem cells from bone marrow in mice to help create tissue cells of other organs, such as the heart, brain and pancreas - a scientific step they hope may lead to potential new ways to replace cells lost in diseases such as diabetes, Parkinson's or Alzheimer's.

Tolfenamic acid appears to reduce esophageal tumors

A new study by researchers at MD Anderson Cancer Center Orlando finds that Tolfenamic acid (TA), a non-steroidal anti-inflammatory drug (NSAID), commonly used to relieve pain, inflammation and migraines has now been found to reduce esophageal tumors.

Researchers reveal how WBCs move to infection or inflammation in the body

Researchers in the biological sciences department in the Faculty of Science at the University of Calgary have revealed how white blood cells move to infection or inflammation in the body; findings which could help lead to developing drug therapies for immune system disorders.

Social interventions may help slow or treat age-related dementia

Scientists at Arizona State University have discovered that older honey bees effectively reverse brain aging when they take on nest responsibilities typically handled by much younger bees.

Scientists reprogram amniotic fluid cells without introduction of extra genes

Stem cells found in amniotic fluid can be transformed into a more versatile state similar to embryonic stem cells, according to a study published today in the journal Molecular Therapy. Scientists from Imperial College London and the UCL Institute of Child Health succeeded in reprogramming amniotic fluid cells without having to introduce extra genes.

Cigarette smoke reduces production of Fallopian tube gene - BAD

Cigarette smoke reduces the production of a Fallopian tube gene known as "BAD", which helps explain the link between smoking and ectopic pregnancy. The finding, from scientists led by Drs Andrew Horne and Colin Duncan at the Medical Research Council (MRC) Centre for Reproductive Health in Edinburgh, UK, was described today at the annual meting of ESHRE (European Society of Human Reproduction and Embryology) in Istanbul.

Treating Sickle Cell Disease with L-Glutamine

By focusing on how best to help patients, researchers can sometimes find solutions that are much simpler than anticipated. That has been the guiding approach to our efforts to develop a treatment for sickle cell disease.

New method promotes selection and growth of dangerous cancer cells

The news a cancer patient most fears is that the disease has spread and become much more difficult to treat. A new method to isolate and grow the most dangerous cancer cells could enable new research into how cancer spreads and, ultimately, how to fight it.

Rodents may hold the key to long and active lifespan

Compared to the average three year life span of a common rat, the 10 to 30 year life of the naked mole rat, a subterranean rodent native to East Africa, is impressive. And compared to the human body, the body of this rodent shows little decline due to aging, maintaining high activity, bone health, reproductive capacity, and cognitive ability throughout its lifetime. Now a collaborative of researchers in Israel and the United States is working to uncover the secret to the small mammal's long - and active - lifespan.

NOTCH1 signaling promotes T-cell acute lymphoblastic leukemia-initiating cell regeneration

Research suggests that patients with leukemia sometimes relapse because standard chemotherapy fails to kill the self-renewing leukemia initiating cells, often referred to as cancer stem cells. In such cancers, the cells lie dormant for a time, only to later begin cloning, resulting in a return and metastasis of the disease.

Researchers identify new gene target for leukemia therapy

Researchers at the University of Cincinnati (UC) Hoxworth Blood Center have discovered a new gene target for leukemia therapy.

GRP78 plays an important role in breast cancers that respond to anti-estrogen therapy

Researchers at Georgetown Lombardi Comprehensive Cancer Center have uncovered a single molecule they say is a major determinant of resistance to anti-estrogen therapy used to treat or prevent breast cancer in high-risk women.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

Osteoarthritis susceptibility: eight potential genes discovered

The largest genome-wide association study (GWAS) of osteoarthritis to date, published Online First in The Lancet, has uncovered eight new genetic variants or loci that appear to increase susceptibility to the most common form of arthritis, which affects about 40% of the world population older than 70 years. These findings bring the total number of osteoarthritis susceptibility genes isolated in European populations to 11.

$Researchers report positive effects of ibuprofen on bone repair after fracture or surgery$

Researchers report positive effects of ibuprofen on bone repair after fracture or surgery

A study conducted at the University of Granada has demonstrated that ibuprofen -a non-steroidal anti-inflammatory drug (NSAID)- has beneficial effects on bone repair after a fracture or following bone surgery.

Changing tissue landscape promotes higher cancer rates in the elderly

Cancers are age-related, much more frequent in the old than in the young. A University of Colorado Cancer Center review published today in the journal Oncogene argues against the conventional wisdom that the accumulation of cancer-causing mutations leads to more cancer in older people, instead positing that it is the changing features of tissue in old age that promote higher cancer rates in the elderly.

Imaging PR status may help identify tumor response to endocrine therapy

Research published in the July issue of The Journal of Nuclear Medicine shows imaging progesterone receptor (PR) status also may be able to identify responders and nonresponders to endocrine therapy at an early stage.

Scientists discover Eya1 enzyme control of pulmonary barrier integrity

Scientists have provided the first evidence that an enzyme called Eya1 protein phosphatase is a critical regulator of lung function and that this may have broad implications for sufferers of a variety of pulmonary diseases.
