Discovery of key event in prostate cancer progression

A study led by researchers at the Ohio State University Comprehensive Cancer Center and Dana-Farber Cancer Institute reveals how late-stage, hormone-independent prostate tumors gain the ability to grow without need of hormones.

Protein produced by gene fusion that may also be targeted for new prostate cancer therapies

Researchers from NewYork-Presbyterian Hospital/Weill Cornell Medical Center have discovered a new gene fusion that is highly expressed in a subset of prostate cancers.

Researchers identify women at risk of gaining excessive weight with Depo-Provera

Researchers at the University of Texas Medical Branch at Galveston have identified women who are likely to gain weight while using depot medroxyprogesterone acetate, more commonly known as Depo-Provera or the birth control shot. These findings dispel the myth that all women who use DMPA will gain weight and will help physicians to counsel patients appropriately.

Major depressive disorder redefined

Researchers from Rhode Island Hospital's department of psychiatry propose that the definition for major depressive disorder (MDD) should be shortened to include only the mood and cognitive symptoms that have been part of the definition in the Diagnostic and Statistical Manual of Mental Disorders (DSM) for the past 35 years.

Cause of colic

Researchers at The University of Texas Health Science Center at Houston say one organism discovered during their study may unlock the key to what causes colic, inconsolable crying in an otherwise healthy baby.

Caspase-8 protein plays an important role in proliferation and invasion of cancer cells

Scientists at Burnham Institute for Medical Research have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. The study was published in the journal Cancer Research on June 15.

Delays could overwhelm hospitals in the event of airborne anthrax attack

A large attack on a major metropolitan area with airborne anthrax could affect more than a million people, necessitating their treatment with powerful antibiotics. A new study finds that in order for a response to be effective, quick detection and treatment are essential, and any delay beyond three days would overwhelm hospitals with critically ill people.

1 in 6 public health workers would not report to work during a pandemic flu emergency

The findings are a significant improvement over a 2005 study conducted by the same research team, in which more than 40 percent of public health employees said they were unlikely to report to work during a pandemic emergency. The new study suggests ways for improving the response of the public health workforce. The results are published in the July 24 edition of the journal PLoS ONE.

Interpersonal effects of appearance-based rejection sensitivity

Three new studies by psychologists at the University at Buffalo have found that after receiving negative feedback about one's appearance, individuals who are highly sensitive to appearance-based rejection withdraw from social interactions and prefer to avoid even those with whom they have close relationships.

Swine flu pandemic could overwhelm critical care beds in England, especially children’s units

Experts in intensive care and anaesthesia have predicted that the current swine flu pandemic could overwhelm critical care beds and ventilators in England, with hospitals on the South East Coast, and in the South West, East of England and East Midlands, being worst hit.

Compact gamma camera for prostate cancer imaging

The U.S. Department of Energy's Brookhaven National Laboratory and Hybridyne Imaging Technologies, Inc., of Toronto, Canada, have won a 2009 R&D 100 Award for developing a compact gamma camera for high-resolution imaging of prostate cancer.

Johns Hopkins-designed animal tuberculosis "tracker" to speed drug and vaccine studies

Johns Hopkins researchers have developed a novel way to monitor in real time the behavior of the TB bacterium in mouse lungs noninvasively pinpointing the exact location of Mycobacterium tuberculosis. The new monitoring system is expected to speed up what is currently a slow and cumbersome process to test the safety and efficacy of various TB drug regimens and vaccines in animals. Plans are already under way for developing a similar system to monitor TB disease in humans.

Identification of progressors in osteoarthritis by combining biochemical and MRI-based markers

A combination of biochemical and MRI markers will allow improved measurement of osteoarthritis (OA) progression. The biomarkers, described in BioMed Central's open access journal Arthritis Research and Therapy, will be useful for the design and interpretation of trials of new disease modifying drugs.
