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.

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.

Early childhood adversity linked with depression and inflammation

When a person injures their knee, it becomes inflamed. When a person has a cold, their throat becomes inflamed. This type of inflammation is the body's natural and protective response to injury. Interestingly, there is growing evidence that a similar process happens when a person experiences psychological trauma. Unfortunately, this type of inflammation can be destructive.

Study shows higher levels of phenolic compounds in organic tomatoes

Study conducted at the University of Barcelona shows that organic tomatoes contain higher levels of phenolic compounds than conventional tomatoes. Phenolic compounds are organic molecules found in many vegetables with proven human health benefits.

Physicists develop new nanoscale materials using moth eyes

Using the compound eyes of the humble moth as their inspiration, an international team of physicists has developed new nanoscale materials that could someday reduce the radiation dosages received by patients getting X-rayed, while improving the resolution of the resulting images.

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.

23andMe identifies seven SNPs associated with breast size

Using data from its unique online research platform, 23andMe, a leading personal genetics company, has identified seven single-nucleotide polymorphisms (SNPs) significantly associated with breast size, including three SNPs also correlated with breast cancer in a genome-wide association study (GWAS) now published online in BMC Medical Genetics.

Scientists develop new animal model to study nonalcoholic steatohepatitis

Scientists at Texas Biomed have developed the laboratory opossum as a new animal model to study the most common liver disease in the nation - afflicting up to 15 million Americans - and for which there is no cure.

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.

Researchers use mouse model of autism to treat CTD

Using a mouse model of autism, researchers at the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center have successfully treated an autism spectrum disorder characterized by severe cognitive impairment.

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.
