Research reveals why people lose hearing as they become old

Although the brain becomes smaller with age, the shrinkage seems to be fast-tracked in older adults with hearing loss, according to the results of a study by researchers from Johns Hopkins and the National Institute on Aging. The findings add to a growing list of health consequences associated with hearing loss, including increased risk of dementia, falls, hospitalizations, and diminished physical and mental health overall.

Research reveals new information about the genetic complexity underpinning schizophrenia

The Icahn School of Medicine at Mount Sinai today announced the publication of two papers in the journal Nature that reveal new information about the genetic complexity underpinning schizophrenia. These collaborative studies represent the largest exome sequencing efforts to date to elucidate this mental illness, and together found that the disorder is likely caused by far more rare genetic mutations than previously suspected.

Inovio Pharmaceuticals unveils new DNA-based cytokine immune activator

Inovio Pharmaceuticals, Inc. today unveiled that the company has developed a new DNA-based cytokine immune activator, interleukin -33 (IL-33), that in combination with optimized DNA vaccines delivered by electroporation increased the potency and efficacy of the therapeutic response to the DNA vaccines in a preclinical study.

New heart tissue could help patients suffering from irreparable damage

In the U.S., someone suffers a heart attack every 34 seconds - their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients could help, and scientists are reporting a promising approach tested with rat cells.

Researchers discover new gene involved in severe childhood epilepsy

A European consortium of epilepsy researchers has reported the discovery of a new gene involved in severe childhood epilepsy. Using a novel combination of technologies, including trio exome sequencing of patient/parental DNA and genetic studies in the tiny larvae of zebrafish, the EuroEPINOMICS RES consortium found that mutations in the gene CHD2 are responsible for a subset of epilepsy patients with symptoms similar to Dravet syndrome - a severe form of childhood epilepsy that is in many patients resistant to currently available anti-epileptic drugs.

New research reveals that humans can use odor to detect fat in food

New research from the Monell Center reveals humans can use the sense of smell to detect dietary fat in food. As food smell almost always is detected before taste, the findings identify one of the first sensory qualities that signals whether a food contains fat.

Researchers identify five new genes associated with increased waist-to-hip ratio

Excess abdominal fat can be a precursor to diseases such as cardiovascular disease, type 2 diabetes and cancer. A person's measure of belly fat is reflected in the ratio of waist circumference to hip circumference, and it is estimated that genetics account for about 30-60 percent of waist-to-hip ratio.

Regular exposure to mild cold may be a sustainable way to help people lose weight

Regular exposure to mild cold may be a healthy and sustainable way to help people lose weight, according to researchers writing in the Cell Press publication Trends in Endocrinology & Metabolism on January 22nd. On the flip side, that means our warm and cozy homes and offices might be partly responsible for our expanding waistlines.

Function of stem cells in blood-forming system is regulated by estrogen, says study

Scientists have known for years that stem cells in male and female sexual organs are regulated differently by their respective hormones. In a surprising discovery, researchers at the Children's Medical Center Research Institute at UT Southwestern (CRI) and Baylor College of Medicine have found that stem cells in the blood-forming system — which is similar in both sexes — also are regulated differently by hormones, with estrogen proving to be an especially prolific promoter of stem cell self-renewal.

Exposing adolescent to marijuana can lead to behavioral alterations in next generation

Exposing adolescent rats to THC (tetrahydrocannabinol) -the primary psychoactive ingredient in marijuana—can lead to molecular and behavioral alterations in the next generation of offspring, even though progeny were not directly exposed to the drug, researchers at the Icahn School of Medicine at Mount Sinai have found.

Gender differences in memory

If your husband is absent-minded, forgets your wedding anniversary or the name of your new neighbor, don't worry. You are not the only one with a forgetful man in the house. Even researchers were surprised by how much men forget.

Hydroxytyrosol in olive oil may help reduce risk of breast cancer

A major component of olive oil, hydroxytyrosol, is the subject of a Houston Methodist study of women who are at increased risk of developing breast cancer. The study focuses on the changes in breast density after one year of treatment and is the first of its kind in the United States.

Scientists develop new genetic platform that yields novel antibiotic from ocean bacteria

Scientists at the University of California, San Diego have developed a new genetic platform that allows efficient production of naturally occurring molecules, and have used it to produce a novel antibiotic compound.

Researchers find that 20% of women with ovarian cancer had inherited mutations in gene pathway

A new study conservatively estimates that one in five women with ovarian cancer has inherited genetic mutations that increase the risk of the disease, according to research at Washington University School of Medicine in St. Louis.

Researchers examine how neurons in brain control arm movements

Sometimes that's how our brains work. When we anticipate a physical act, such as reaching for the keys we noticed on the table, the neurons that control the task adopt a state of readiness, like sprinters bent into a crouch.

Jackson Laboratory collaborates with Seoul National University to develop new mouse models, tumor repository

The Jackson Laboratory, in collaboration with Seoul National University, will receive a five-year, $7.5 million grant from the South Korean government for a large-scale cancer genomics project employing the latest sequencing technology and special JAX mouse models that can host human tumors.

Chinese and American researchers introduce new approach to gene therapy

Resistance of tumor cells toward multiple cytostatic drugs is a serious problem in cancer treatment. In the journal Angewandte Chemie, a team of Chinese and American researchers has now introduced a new approach to gene therapy that could counter this problem: The gene that codes for resistance is “silenced” through the use of an ingenious nanocomplex.

Lack of SIRT1 protein in the liver leads to lower levels of liver FGF21

A new study led by Boston University School of Medicine demonstrates that the abnormal metabolism linked to obesity could be regulated in part by the interaction of two metabolic regulators, called the NAD-dependent deacetylase SIRT1 and fibroblast growth factor 21 (FGF21). Using experimental models, the researchers found that a lack of SIRT1 protein in the liver led to lower levels of a liver secreted protein FGF21, which resulted in an increased likelihood of developing fatty liver disease and obesity.
