Kids who are abused or bullied may age faster

The study finds that violence-related stress in children affects telomeres - special DNA sequences found at the tips of chromosomes. Telomeres, which prevent DNA from unravelling, get shorter each time cells divide, which limits the number of times cells can divide. Shorter telomeres have been linked to poorer survival and chronic diseases. Previous research has shown that smoking, obesity, mental-health disorders and stress may accelerate the process of telomere loss. This suggests that telomere length may reflect a person's biological age as well as their chronological age.

Self-degradation response to antidepressant Zoloft observed in yeast cells

Princeton University researchers have observed a self-degradation response to the antidepressant Zoloft in yeast cells that could help provide new answers to lingering questions among scientists about how antidepressants work, as well as support the idea that depression is not solely linked to the neurotransmitter serotonin.

RANK inhibitor-chemotherapy combination may have important therapeutic effects against breast cancer

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have shown that overactivation of the RANK signalling pathway promotes the initiation, progression and metastasis of tumours in human breast epithelial cells by dedifferentiation of breast cells to stem cells. The results of this study have been advanced in the electronic edition of the journal Cancer Research.

Bile plays a critical role in development of Barrett's esophagus

For many people with gastroesophageal reflux disease or GERD, acid reflux drugs are the answer to their woes, curbing the chronic heartburn and regurgitation of food or sour liquid characteristic of the disorder. But when it comes to Barrett's esophagus, a condition commonly found in people with GERD, acid control may be less important than beating back another bodily fluid - bile.

New microfluidic device can harvest rare circulating tumor cells from blood

A research collaboration between the Wyss Institute for Biologically Inspired Engineering at Harvard University and Children's Hospital Boston has created a microfluidic device that can harvest rare circulating tumor cells (CTCs) from blood to enable their expansion in culture for analysis.

Omega-3 supplements do not improve diastolic function in older adults

Over the past three decades, researchers have firmly established that the omega-3 fatty acids in fish oil, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have healthy effects on the heart. Omega-3 fatty acids seem to help both in preventing cardiovascular disease as well as in preventing future heart attacks, strokes, and other adverse events in people who have established cardiovascular disease.

MMP-10 gene plays a dual role in lung cancer

A single gene that promotes initial development of the most common form of lung cancer and its lethal metastases has been identified by researchers at Mayo Clinic in Florida.

Researchers identify fibronectin strain-sensitive probes

Fibronectin plays a major role in wound healing and embryonic development. The protein, which is located in the extracellular matrix of cells, has also been linked to pathological conditions including cancer and fibrosis.

Expression of specific GPCRs appears to play a role in prognosis of CLL

Researchers at the University of California-San Diego School of Medicine have shown that G protein-coupled receptor expression may predict the prognosis of patients with chronic lymphocytic leukemia. Their findings may identify new ways to treat such patients.

Oregano ingredient could treat prostate cancer

Oregano, the common pizza and pasta seasoning herb, has long been known to possess a variety of beneficial health effects, but a new study by researchers at Long Island University (LIU) indicates that an ingredient of this spice could potentially be used to treat prostate cancer, the second leading cause of cancer death in American men.

Non-coding RNA gives off biological signals during viral infection

Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) - RNA molecules that do not translate into proteins - play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.

Distracted driving more prevalent in college students

According to the California Department of Motor Vehicles (CADMV), distracted driving is on the rise due to an increase in the use of cell phones and other electronic devices and the increasing importance of these devices in individuals' lives. Studies have shown that phoning and driving increases the risk of crashes four-fold, with hands free and hand held devices equally dangerous. Texting increases this risk 8-16 times.

ASH report urges federal agencies to invest in 7 distinct areas of research

The American Society of Hematology (ASH), the world's largest professional society committed to the study and treatment of blood disorders, today issued a report urging federal agencies to coordinate hematology research funding around seven specific high-need areas that would produce the greatest impact and translate into improvements in patient care in the United States.

Researchers develop five different molecular models of the voltage sensor

Every thought, every movement, every heartbeat is controlled by lightning-quick electrical impulses in the brain, the muscles, and the heart. But too much electrical excitability in the membranes of the cells can cause things like epilepsy and cardiac arrhythmia. A research group at Linköping University has now published new discoveries that can lead to new medicines for these diseases.

Scientists discover new mechanism for regulation of AQP function

Scientists at Aston University (UK) have identified a new mechanism responsible for regulating the flow of water into and out of cells. This discovery will improve understanding of how the body maintains its water balance in health and disease.

Impaired mitochondrial function may play a major role in mood and psychotic disorders

Janssen Research & Development, LLC announced today the publication of an article that reviews the growing evidence that impaired mitochondrial function may play a major role in mood and psychotic disorders.

CML and B-ALL arise from the long-term haematopoietic stem cells

Although people generally talk about "cancer", it is clear that the disease occurs in a bewildering variety of forms. Even single groups of cancers, such as those of the white blood cells, may show widely differing properties. How do the various cancers arise and what factors determine their progression? Clues to these two issues, at least for leukaemias, have now been provided by Boris Kovacic and colleagues at the University of Veterinary Medicine, Vienna.

Clinical trial to evaluate IGF-1 in children with SHANK3 deficiency

In an important test of one of the first drugs to target core symptoms of autism, researchers at Mount Sinai School of Medicine are undertaking a pilot clinical trial to evaluate insulin-like growth factor (IGF-1) in children who have SHANK3 deficiency (also known as 22q13 Deletion Syndrome or Phelan-McDermid Syndrome), a known cause of autism spectrum disorder (ASD).
