Cystic fibrosis patient receives generous 'gift of life'

Meara Schmidt, 28, almost died a few weeks ago. Lying in her hospital bed at UCLA, the seriously ill cystic fibrosis patient felt herself slipping away and her life flashing by. But then the image of her husband appeared, and she knew she was not ready to go.

New vaccine candidate against leading cause of hospital-acquired infections

Researchers at Brigham and Women's Hospital (BWH) have discovered a new vaccine candidate for the bacterium Pseudomonas aeruginosa taking advantage of a new mechanism of immunity.

Safe optimal concentration of propolis against radiation-induced damage

Researchers determined the amount of propolis offering maximum protection against ionised radiations without being toxic to blood cells.

FDA approves KRAS gene mutation test for colorectal cancer

The U.S. Food and Drug Administration today approved the first genetic test that can help some colorectal cancer (CRC) patients and their doctors determine if the drug Erbitux (cetuximab) would be an effective treatment based on the absence of a gene mutation. The therascreen KRAS RGQ PCR Kit can provide information about the KRAS gene mutation in patients whose CRC has spread to other parts of their body (metastasized).

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

Study represents starting point for future clinical applications using propolis

A team of researchers from the University of Valencia, the Universitat Politècnica de València, the University Hospital La Fe and the Universitat Autònoma de Barcelona conducted in vitro studies of cytotoxicity (cellular affection) to assess the optimal concentration level of propolis in which this natural substance extracted from bee resin would offer the maximum protection against ionised radiation and not be toxic for blood cells.

PHF21A gene plays a big role in Potocki-Shaffer syndrome

A gene whose mutation results in malformed faces and skulls as well as mental retardation has been found by scientists.

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.

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.

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.

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.

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.

Intense war against malaria outlined by two studies in The American Journal of Tropical Medicine and Hygiene

A pair of provocative studies in the July 2012 issue of The American Journal of Tropical Medicine and Hygiene (AJTMH) provides a window into the intense ground war now underway against malaria.

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.

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.
