Being left-handed has been linked to many mental disorders, but Yale researcher Jadon Webb and his colleagues have found that among those with mental illnesses, people with psychotic disorders like schizophrenia are much more likely to be left-handed than those with mood disorders like depression or bipolar syndrome.
The new study is published in the October-December 2013 issue of the journal SAGE Open. (more…)
Study finds women’s breast tissue ages faster than the rest of the body
Everyone grows older, but scientists don’t really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process.
Published in the Oct. 21 edition of the journal Genome Biology, the findings could offer valuable insights to benefit cancer and stem cell research. (more…)
Eleven regions of the human genome have been newly discovered to influence the onset of Alzheimer’s disease. The findings stem from the largest international study ever conducted on this disorder, which causes gradual memory loss and other forms of cognitive decline in older people.
As of 2009, 10 genes were known to be related to Alzheimer’s, the result of about a quarter-century of research. Yet the reasons behind individual susceptibility or resistance to the disease continued to be poorly understood. In February of 2011, four international research groups studying Alzheimer’s disease genetics united to more quickly identify other genes related to the disorder. (more…)
When Dr. Dieter Lindskog first began walking the halls of Yale School of Medicine a decade ago, people would stop him often to ask, “Are you by any chance related to …?” Now they stop him rarely, either because they know the answer or are too young to recognize the famous name — that of the grandfather who upended accepted tenets of medical practice and, in doing so, gave birth to the science and art of modern oncology.(more…)
A class of molecules called microRNAs may offer cancer patients two ways to combat their disease.
Researchers at Princeton University have found that microRNAs — small bits of genetic material capable of repressing the expression of certain genes — may serve as both therapeutic targets and predictors of metastasis, or a cancer’s spread from its initial site to other parts of the body. The research was published in the journal Cancer Cell. (more…)
When the “war on cancer” was declared with the signing of the National Cancer Act in 1971, identifying potential physical traits, or biomarkers, that would allow doctors to detect the disease early on was a significant goal. To this day, progress in the battle against cancer depends on understanding the underlying causes and molecular mechanisms of the disease. (more…)
One in 2,000 people in the UK are estimated to be carrying variant Creutzfeldt-Jakob disease (vCJD) proteins, according to a study led by Professor Sebastian Brandner (UCL Institute of Neurology).(more…)
Project will utilize Ohio State’s new microscopy facility
COLUMBUS, Ohio — Armed with microscopes, computers and an innovative way to study metals, researchers at The Ohio State University and their partners are building a database of new titanium alloys.
The goal: to reduce the stress that pins, plates and other medical implants put on healthy bones. (more…)
