The researchers used TMS to send magnetic pulses to a region of the right cerebral hemisphere in the brain known as the frontal eye field. These magnetic pulses activate the cortical neurons located within the range of the magnetic field, which modifies their activity in a painless and temporary manner. to the authors, findings from this study could lead to the development of new rehabilitation t

The eye is the window of the body through which it feels its way and by which medical doctors sometimes ascertain the health status of the body. Currently, researchers have developed a simple eye test which might someday offer an effective way to identify patients who are at risk for stroke, reports Sade Oguntola. During a routine examination, eye doctors can detect signs of certain health proble
UGA Study Shows Why Hypertension Increases Damage To Eyes Of Diabetic Patients

Athens, Ga. - Hypertension frequently coexists in patients with diabetes. A new University of Georgia study shows why the co-morbid conditions can result in impaired vision. Results showed early signals of cell death in eyes from diabetic animals within the first six weeks of elevated blood pressure.The study examined animals with early and established stages of diabetes that also had hypertensio

Sending patient images to ophthalmologists via smartphone may be an option for emergency room doctors looking to make a quick eye-related diagnosis, a new study suggests.Two ophthalmologists gave higher quality ratings to inner-eye photos when they looked at the images on an iPhone as compared to a desktop computer, according to results published Monday in the Archives of Ophthalmology.That may m
Stem Cell Breakthrough Significant for Degenerative Diseases
Posted by Bharat (#1) 4363 days ago (Editorial)
Researchers in Israel have achieved a significant global milestone in stem cell technology: they have created the first human embryonic stem cell (hESC) lines that are free of animal contamination and whose production complies with Good Manufacturing Practices (GMP). The achievement paves the way for developing clinical treatments that use hESCs to treat degenerative diseases like age-related mac
Cheaper, Faster Diagnosis in Heterogeneous Disease Via Exome Sequencing
Posted by Bharat (#1) 4365 days ago (Editorial)
The first report of the diagnostic use of the technique of exome sequencing, where short sequences of DNA are analysed, shows that it can give good results at low cost, a researcher from The Netherlands told the annual conference of the European Society of Human Genetics. The scientists were able to perform a genetic diagnosis in around 20% of 100 cases of patients with intellectual disability (I

These are the visual warning signs of stroke. The other signs of stroke include sudden numbness or weakness of the arm or leg or face, typically on just one side of the body; trouble walking because of dizziness or loss of balance or coordination; slurred speech; or bad headache. In a large stroke (caused by a blood clot or bleeding in the brain), these symptoms happen all at once. In a smaller s

Insomnia in some adults may be driven by a fear of the dark, Canadian researcherssay.In their small study of 93 college men and women, Ryerson University researchers found more poor sleepers than good sleepers confessed a fear of the dark."I think the most surprising part of the study is that people told us," says researcher Colleen Carney, PhD, associate professor of psychology at Ryerson Univer
