Study shows cells from different Parkinson’s patients have unique drug responses

Researchers have taken a step toward personalized medicine for Parkinson's disease, by investigating signs of the disease in patient-derived cells and testing how the cells respond to drug treatments.

Eltrombopag can raise blood cell levels in some people with severe aplastic anemia

Eltrombopag, a drug that was designed to stimulate production of platelets from the bone marrow and thereby improve blood clotting, can raise blood cell levels in some people with severe aplastic anemia who have failed all standard therapies.

Neighboring non-cancer cells may contribute to drug resistance

One of cancer's most frightening characteristics is its ability to return after treatment. In the case of many forms of cancer, including the skin cancer known as melanoma, tailored drugs can eradicate cancer cells in the lab, but often produce only partial, temporary responses in patients. One of the burning questions in the field of cancer research has been and remains: how does cancer evade drug treatment?

Researchers use maternal blood sample to sequence genome of an unborn baby

Researchers at the Stanford University School of Medicine have for the first time sequenced the genome of an unborn baby using only a blood sample from the mother.

Interfascicular matrix essential for tendon function

Tendon disorders cost the UK economy more than -7bn a year and now scientists at Queen Mary, University of London have identified a vital component of tendons which could help treat them.

Lower pH reduces ability of ASL to kill bacteria in CF airways

The human airway is a pretty inhospitable place for microbes. There are numerous immune defense mechanisms poised to kill or remove inhaled bacteria before they can cause problems. But cystic fibrosis (CF) disrupts these defenses, leaving patients particularly susceptible to airway infection, which is the major cause of disease and death in CF.

Scientists identify causative link between oncometabolite and onset of AML

A team of international scientists led by principal investigator Dr. Tak Mak at the Princess Margaret Cancer Centre, University Health Network, has identified a causative link between the product of a mutated metabolic enzyme and the onset of acute myeloid leukemia (AML), one of the most common types of leukemia in adults.

Alcoholic liver disease risk only ‘modestly’ affected by genetic factors

Research has suggested that environmental factors have a greater impact on the risk of alcoholic liver disease (ALD) than genetic predisposition.

Strawberry extracts actively stimulate proteins that offer protection against cardiovascular disease

Strawberries, the traditional summer treat associated with Wimbledon could be serving up some unexpected health benefits.

New research approach can help predict the 'tenability' of antibiotics

Research by Wageningen University, part of Wageningen UR, has shown that the development of bacteria with resistance against the antibiotic cefotaxime occurs more often and more predictably than was previously assumed. Bacterial populations were found to have many mutations that increase resistance and therefore have a negative effect on public health.

The Jeffrey Epstein VI Foundation supports Genetic Initiative at CCFA

The Jeffrey Epstein VI Foundation, which actively supports science research, has given substantial support to the Crohn's and Colitis Foundation of America to continue its Genetic Initiative to find a cure for the diseases.

UCLA Laboratory of Neuro Imaging to partner in new effort to combat Alzheimer's

Since 2004, UCLA's Laboratory of Neuro Imaging (LONI) has been responsible for receiving, organizing, archiving and disseminating the stream of data generated by the Alzheimer's Disease Neuroimaging Initiative (ADNI), an ambitious, worldwide effort by scientists to define the progression of Alzheimer's disease.

Study examines how cells exploit gene sequences to cope with toxic stress

Toxic chemicals wreak havoc on cells, damaging DNA and other critical molecules. A new study from researchers at MIT and the University at Albany reveals how a molecular emergency-response system shifts the cell into damage-control mode and helps it survive such attacks by rapidly producing proteins that counteract the harm.

Researchers identify mechanism responsible for inhibition of AMPK activity in the hypothalamus

In the complex chain of molecular events that underlie eating behaviors and body weight, the AMP-activated protein kinase (AMPK) enzyme has proven to be a critical link.

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.

TMC receives NIH grant to evaluate pepducin in heart disease patients

Tufts Medical Center researchers are developing a first-of-its-kind drug to prevent deadly blood clots in heart disease patients, without the risk of serious bleeding associated with current medications. The National Heart, Lung, and Blood Institute of the National Institutes of Health has just awarded the team led by Athan Kuliopulos, MD, PhD, a $10 million grant to start testing a drug based on this novel technology.

Important insight into association between childhood maltreatment and suicide

Exposure to childhood maltreatment increases the risk for most psychiatric disorders as well as many negative consequences of these conditions. This new study, by Dr. Gustavo Turecki and colleagues at McGill University, Canada, provides important insight into one of the most extreme outcomes, suicide.

Global warming may stimulate growth of cyanobacteria

Cyanobacteria are among the most primitive living beings, aged over 3,500 million years old. These aquatic microorganisms helped to oxygenate the earth-atmosphere. At present their populations are increasing in size without stopping. It appears that global warming may be behind the rise in their numbers and may also lead toan increase in the amount of toxins produced by some of these populations.

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.
