Inner ear supporting cells protect hair cells by secreting HSP70

An underlying cause of hearing loss is the death of sensory hair cells in the inner ear, which can be damaged in response to a variety of factors including the use of aminoglycoside antibiotics.

Study provides information on neural pathways involved in human word learning

Language is a uniquely human ability. The average vocabulary of a person consists of about thirty thousand words, although people show individual differences in their ability to learn a new language.

New species of adenovirus can spread from monkey to human, say researchers

Adenoviruses commonly infect humans, causing colds, flu-like symptoms and sometimes even death, but now UC San Francisco researchers have discovered that a new species of adenovirus can spread from primate to primate, and potentially from monkey to human.

Finding could aid in delivering personalized cancer medicine based on individual's genetics

Scientists at the Princess Margaret Cancer Centre have discovered a function of the tumor suppressor gene PTEN that helps explain why certain promising therapies fail in many cancer patients, a finding that could aid in delivering tailored, personalized cancer medicine based on an individual's genetics.

EGFR mutation testing dropped once funding from pharmaceutical industry discontinued

Significant advances have taken place in the management of patients with advanced and metastatic non-small-cell lung cancer over the last 5 years. Traditionally, all advanced NSCLC patients were treated in a similar manner.

Researchers find how brain cells communicate with each other in different voice tones

Brain cells talk to each other in a variety of tones. Sometimes they speak loudly but other times struggle to be heard. For many years scientists have asked why and how brain cells change tones so frequently. Today National Institutes of Health researchers showed that brief bursts of chemical energy coming from rapidly moving power plants, called mitochondria, may tune brain cell communication.

Supporting cells in the inner ear can help repair damaged sensory hair cells, say researchers

Researchers have found in mice that supporting cells in the inner ear, once thought to serve only a structural role, can actively help repair damaged sensory hair cells, the functional cells that turn vibrations into the electrical signals that the brain recognizes as sound.

EPHB2 overexpressed in malignant pleural mesothelioma cell lines, find researchers

Malignant mesothelioma is a rare asbestos-associated malignancy with limited therapeutic options. Despite advances in the treatment, the median survival remains 12 months from the time of diagnosis. Increased understanding of the molecular basis for the diverse signaling pathways involved in cancer progression should promote the discovery of novel biomarkers for early diagnosis and potentially lead to more effective therapeutic tools for the disease.

Researchers explain how gut bacteria can inactivate cardiac drugs

For decades, doctors have understood that microbes in the human gut can influence how certain drugs work in the body - by either activating or inactivating specific compounds, but questions have long remained about exactly how the process works.

Researchers uncover way to stop cancer cells using HIF-1 gene through synthetic biology approach

Scientists have discovered a new molecule that prevents cancer cells from responding and surviving when starved of oxygen and which could be developed into new treatments for the disease, according to new research published in the Journal of the American Chemical Society today (Friday).

Silk implants placed in brain of animals may help stop progression of epilepsy

Silk has walked straight off the runway and into the lab. According to a new study published in the Journal of Clinical Investigation, silk implants placed in the brain of laboratory animals and designed to release a specific chemical, adenosine, may help stop the progression of epilepsy.

Gene expression profile test accurately predicts likelihood of metastasis in thymoma patients

Patients diagnosed with thymoma, a rare cancer of the thymus gland, may be able to avoid certain cancer treatments associated with severe adverse events if the results of a new test reveal they are at low risk of metastasis, according to a study published today in the journal PLOS ONE.

Researchers to study knowledge and satisfaction of women who choose DNA prenatal screening test

A recently available DNA-based prenatal blood test used to screen pregnancies for Down syndrome and similar chromosome abnormalities in high-risk women is moving a step closer to use in the general pregnancy population.

Study finds that higher-frequency electric current stimulation of the spinal cord reduces pain faster

An animal study in the August issue of Anesthesiology suggests that higher-frequency electric current stimulation of the spinal cord reduced pain quicker and better reached nerves not affected by traditionally used frequencies. A higher frequency and intensity controlled pain faster and more effectively, the study found.

Study may lead to personalized treatments for mitochondrial energy disorders

Researchers have identified a master network of signaling molecules that acts like a "fuse box" to regulate the cellular effects of defective energy flow in mitochondrial respiratory chain diseases—a diverse set of difficult-to-treat genetic-based energy disorders.
