Prostate Cancer :: Prostate cancer – speeding development of novel tracer

The collaborative work being performed by professionals across medical disciplines in the promising area of molecular imaging — from research scientists to nuclear medicine physicians, urologists, radiochemists and even veterinarians — provides encouraging news in fighting prostate cancer. This type of progressive — or translational — research can be seen in two papers published in the January issue of the Journal of Nuclear Medicine.

Brain :: How appetite-stimulating brain cells work overtime during fasting

During periods of fasting, brain cells responsible for stimulating the appetite make sure that you stay hungry. Now, a new study of mice reported in the January issue of the journal Cell Metabolism, published by Cell Press, reveals the complex series of molecular events that keep those neurons active.

Mad Cow Disease :: Cows Engineered to Lack Mad Cow Disease

Scientists have genetically engineered a dozen cows to be free from the proteins that cause Mad Cow Disease. The research published in the online journal Nature Biotechnology could be used as a tool that would help researchers better understand similar brain-wasting diseases in humans.

Imaging :: Imaging pinpoints brain regions that ‘see the future’

Using brain imaging, researchers from Washington University in St. Louis have identified several brain regions that are involved in the uniquely human ability to envision future events. The study, to be published in the journal PNAS, provides evidence that memory and future thought are highly interrelated and helps explain why future thought may be impossible without memories. Findings suggest that envisioning the future may be a critical prerequisite for many higher-level planning processes.

Stress :: Patients with PTSD experience less pain sensitivity

Patients with posttraumatic stress disorder show reduced pain sensitivity, a pattern that may be related to altered pain processing in the brain, according to a report in the January issue of the Archives of General Psychiatry, one of the JAMA/Archives journals.

Brain :: High-normal uric acid linked with mild cognitive impairment in the elderly

Researchers at the Johns Hopkins and Yale university medical schools have found that a simple blood test to measure uric acid, a measure of kidney function, might reveal a risk factor for cognitive problems in old age. Of 96 community-dwelling adults aged 60 to 92 years, those with uric-acid levels at the high end of the normal range had the lowest scores on tests of mental processing speed, verbal memory and working memory.

Rift Valley Fever :: Rift valley fever kills 52 in Kenya – update

The death toll from the outbreak of Rift Valley fever in Kenya’s Wajir District has risen to 52 after four people reportedly died. According to reports, the Rift Valley fever killed three other people in neighbouring Isiolo District.

Smoking :: Smokers hooked on 5000 cigarettes a year in UK

The average British smoker is ‘hooked’ on more than 5000 cigarettes a year, says a hard-hitting government campaign due to air in the New Year.

Parkinson’s Disease :: Brain protein pathway may be a key to parkinson’s disease

A protein called HIPK2 is essential for the survival of dopamine neurons, the cells lost in Parkinson’s disease, according to a study in mice. The results suggest that the molecular pathway in which the protein functions could be a possible new target for therapy, the study authors say.

Stroke :: New treatments prevent brain injury hours after stroke

Two novel treatments — a basic compound found in every cell in the body and an extract of green tea — may prevent brain damage caused from stroke, according to two studies in rats led by a researcher at the San Francisco VA Medical Center.
