Mediomics receives additional $460,000 in STTR Phase II grant for PINCER protein assay development

Mediomics, LLC has received an additional $460,000 in a renewal of its 2nd year STTR Phase II grant (R42GM079891) from the National Institute of General Medical Sciences. Since 2007, Mediomics has received over one million dollars of STTR funding to develop its quick and sensitive homogenous PINCER™ protein assay. The major goal of the second year project is to further increase the sensitivity of the biosensor.

Teenage boys more likely to develop high blood pressure in early adulthood, researchers reveal

Ben-Gurion University of the Negev researchers reveal in a new, large-scale study that "normal" blood pressure at age 17 can still predict hypertension at early adulthood and that teenage boys are three to four times more likely to develop high blood pressure in early adulthood than girls.

Late preterm births risk infant respiratory illness: Study

Babies born between 34 weeks and 37 weeks gestation are much more likely to have respiratory illness compared to infants born at full term, and their risk of respiratory illness decreases with each additional week of gestation until 38 weeks, researchers report.

New study reveals potential role of TGF-β1 in kidney disease

Fibrosis in the kidney is one of the key causes of progressive renal failure. High levels of the inflammatory molecule TGF-β1 in the kidney tubules due to tissue damage can cause fibrosis as well as nephron degeneration, resulting in loss of kidney function. To clarify the mechanisms regulating TGF-β1-mediated renal fibrosis, Koesters et al expressed high levels of TGF-β1 in renal tubules of mice. Nephron degeneration in this system was mediated by decomposition of the tubular cells. These data suggest that TGF-β1 may play a novel role in cell death of renal cells, thus contributing to renal fibrosis.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.

Delirium increases risk of death in older patients

A review and analysis of previous research indicates that delirium in elderly patients is associated with an increased risk of death, dementia, and institutionalization, independent of age, co-existing illnesses or illness severity, according to a study in the July 28 issue of JAMA.

CIHR grants $2.5 million to probe impact of physical activity on breast cancer

Over the next five years, a diverse, multi-disciplinary team of researchers led by Dr. Kerry Courneya of the University of Alberta and Dr. Christine Friedenreich of Alberta Health Services will conduct a series of five large research projects to probe the impacts of physical activity on breast cancer thanks to a $2.5 million team grant over five years from the Canadian Institutes of Health Research (CIHR).

Calcium transfer impacts fuel mechanism for normal cell metabolism

University of Pennsylvania School of Medicine researchers have described a previously unknown biological mechanism in cells that prevents them from cannibalizing themselves for fuel. The mechanism involves the fuel used by cells under normal conditions and relies on an ongoing transfer of calcium between two cell components via an ion channel. Without this transfer, cells start consuming themselves as a way of to get enough energy.

Study shows music alleviates anxiety, depression

For decades research has shown that listening to music alleviates anxiety and depression, enhances mood, and can increase cognitive functioning, such as spatial awareness. However, until now, research has not addressed how we listen to music. For instance, is the cognitive benefit still the same if we listen to music whilst performing a task, rather than before it? Further, how does our preference for a particular type of music affect performance? A new study from Applied Cognitive Psychology shows that listening to music that one likes whilst performing a serial recall task does not help performance any more than listening to music one does not enjoy.

Scientists unveil new biomarkers for stroke, coronary heart disease

Analysis of blood protein data from the Women's Health Initiative cohorts has revealed new biomarkers for stroke and coronary heart disease (CHD). Research published in BioMed Central's open access journal Genome Medicine found that beta-2 microglobulin (B2M) levels were significantly elevated in postmenopausal women with CHD, and insulin-like growth factor binding protein 4 (IGFBP4) was strongly associated with stroke.

Research on method to open blood-brain barrier for safe cancer drug delivery

One of the human body's most powerful defensive tools, the blood-brain barrier is a chemical labyrinth that prevents toxins and viruses in the bloodstream from reaching the brain. This foolproof security system, however, limits the ability of physicians to deliver drugs directly to the brain, making it difficult to treat brain tumors. Researchers at Rensselaer Polytechnic Institute are endeavoring to solve this problem by investigating new methods for bypassing the blood-brain barrier and combating the spread of brain cancer.

Scientists develop novel chemotherapeutic method for anticancer drug delivery

Combining nature and Greek mythology, researchers at the Technion-Israel Institute of Technology have developed a tiny "Trojan Horse" system for delivering cancer-fighting drugs. With this system, the drugs are delivered only once they are inside the cancerous cells, so there is no damage to the healthy cells in the surrounding area.

Attaching transferrin to nanoparticle surface can kill cancer cells

A normally benign protein found in the human body appears to be able - when paired with nanoparticles - to zero in on and kill certain cancer cells, without having to also load those particles with chemotherapy drugs.The finding could lead to a new strategy for targeted cancer therapies, according to the University of North Carolina at Chapel Hill scientists who made the discovery.

Studies that compare treatment options for carotid artery disease provide no clear answer, physician reports

A review of scientific studies that compares two treatments for preventing strokes due carotid artery disease provides no clear answer on which treatment is better, a UT Southwestern Medical Center physician reports in an editorial in today's issue of the Archives of Internal Medicine.

Researchers reveal biological rationale for why corticosteroids help people with lupus

Researchers at UT Southwestern Medical Center have uncovered the biological rationale for why large doses of corticosteroids given repeatedly over several weeks may help individuals with lupus, a chronic inflammatory disease that affects more than 1 million people in the U.S.

'Quit Smoking' Habit Changer program more effective than other popular methods

Today findings from a recent Anderson Analytics market research study were released that examined the underlying reasons for success of common methods used to stop smoking versus a new online approach. This study compared participants that completed the 42-day "Quit Smoking" program by Habit Changer against participants who used nicotine-replacement therapies or other alternatives to quit or reduce intake of cigarettes. According to the Centers for Disease Control and Prevention (CDCP), roughly 9.2 million smokers attempt to quit annually.

Neurodegenerative disease-causing infectious protein can erupt from healthy brain tissue: Study

In a startling new study that involved research on both sides of the Atlantic, scientists from The Scripps Research Institute in Florida and the University College London Institute of Neurology in England have shown for the first time that abnormal prions, bits of infectious protein devoid of DNA or RNA that can cause fatal neurodegenerative disease, can suddenly erupt from healthy brain tissue.
