Electronic app may help schizophrenia patients to avoid hallucinations

When a patient afflicted with schizophrenia hears inner voices something is taking place inside the brain that prevents the individual from perceiving real voices. A simple electronic application may help the patient learn to shift focus.

People with CD36 gene may like high-fat foods more than others

A preference for fatty foods has a genetic basis, according to researchers, who discovered that people with certain forms of the CD36 gene may like high-fat foods more than those who have other forms of this gene.

Urine-based biomarkers may lead to development of test for high-risk prostate cancer

Initial results of a multicenter study coordinated by researchers at Fred Hutchinson Cancer Research Center indicates that two investigational urine-based biomarkers are associated with prostate cancers that are likely to be aggressive and potentially life-threatening among men who take a "watchful waiting," or active-surveillance approach to manage their disease.

Mental illness suspect genes are among the most environmentally responsive regulatory mechanisms

For the first time, scientists have tracked the activity, across the lifespan, of an environmentally responsive regulatory mechanism that turns genes on and off in the brain's executive hub.

Scientists identify molecular switch that controls ATF2's dual functions

The National Cancer Institute (NCI) estimates that as many as one in 51 men and women will be diagnosed with melanoma-the deadliest form of skin cancer-at some point during their lifetimes. A research team led by Ze'ev Ronai, Ph.D. at Sanford-Burnham Medical Research Institute (Sanford-Burnham) is working to unravel the molecular mechanisms underlying the development and progression of this disease in hopes of improving prevention and treatment strategies

Small molecules at cell's membrane enable cell movement

Cell biologists at Johns Hopkins have identified key steps in how certain molecules alter a cell's skeletal shape and drive the cell's movement.

Molecular subtypes of lung cancer manifest as different diseases

Different kinds of lung cancer behave in different ways, suggesting they are fundamentally different diseases. According to a University of Colorado Cancer Center study published in Cancer, the official journal of the American Cancer Society, different subgroups of non-small cell lung cancer (NSCLC) show distinct patterns of spread in the body.

New procedure rapidly induces nerve regeneration

American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research.

International conference focuses on where and how memory is formed

The University of Haifa is hosting an international conference of leading brain researchers from around the world next week, where the participants will be attempting to answer the question of where and how memory is stored; or in less ordinary terms: "Cell and molecular mechanisms of memory formation".

Immune cells from healthy individuals effectively kill cancer cells

Immune cells from healthy individuals can be the new immune cure for cancer. This treatment can kill cancer cells without destroying neighbouring cells. The hope is to eradicate cancer for ever.

Chronic hyperglycemia may lead to cardiac damage

A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health suggests that hyperglycemia (high blood sugar) injures the heart, even in patients without a history of heart disease or diabetes.

Scientists uncover genes that govern male and female behaviors

Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how? Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.

Researchers tease out toxic role of tau oligomers in Alzheimer's

One of the most distinctive signs of the development of Alzheimer's disease is a change in the behavior of a protein that neuroscientists call tau. In normal brains, tau is present in individual units essential to neuron health. In the cells of Alzheimer's brains, by contrast, tau proteins aggregate into twisted structures known as "neurofibrillary tangles."

Scientists discover new mechanisms by which RNA drugs can control gene activity

Small RNA-based nucleic acid drugs represent a promising new class of therapeutic agents for silencing abnormal or overactive disease-causing genes, and researchers have discovered new mechanisms by which RNA drugs can control gene activity.

Researchers identify fexinidazole as potential new therapy for visceral leishmaniasis

Researchers at the University of Dundee have identified fexinidazole as a possible, much-needed, new treatment for the parasitic disease visceral leishmaniasis.

Strong link between triglyceride levels and ischemic stroke in older women

In a surprising finding with significant implications for older women, researchers at Albert Einstein College of Medicine of Yeshiva University and NYU School of Medicine have found that high levels of triglycerides (blood fats) are the strongest risk factor for the most common type of stroke in older women – more of a risk factor than elevated levels of total cholesterol or of low-density lipoprotein (LDL) cholesterol.

Multiple DNA repair defect in monocytes

Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood - so-called monocytes - are extremely sensitive to reactive oxygen species (ROS).

Silver as effective as leading chemotherapy drugs

The internet is awash with stories of how silver can be used to treat cancer. Now, lab tests have shown that it is as effective as the leading chemotherapy drug - and may have fewer side-effects.

Version of 'Goldilocks' gene could determine future treatment for TB patients

'Goldilocks' gene could determine best treatment for TB patients Tuberculosis patients may receive treatments in the future according to what version they have of a single 'Goldilocks' gene, says an international research team from Oxford University, King's College London, Vietnam and the USA.

GIS study sheds light on complex regulation of gene expression

Genome Institute of Singapore's (GIS) Associate Director of Genomic Technologies, Dr Yijun RUAN, led a continuing study on the human genome spatial/structural configuration, revealing how genes interact/communicate and influence each other, even when they are located far away from each other.
