ONCOLOGY A new target in acute myeloid leukemia Acute myeloid leukemia, a common leukemia in adults, is characterized by aberrant proliferation of cancerous bone marrow cells. Activating mutations in a protein receptor known as FLT3 receptor are amo…
Study Shows Why Hypertension Increases Damage To Eyes Of Diabetic Patients
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 s…
Exposure To Chemical In Drinking Water In The Womb And Early Childhood May Affect Vision
Prenatal and early childhood exposure to the chemical solvent tetrachloroethylene (PCE) found in drinking water may be associated with long-term visual impairments, particularly in the area of color discrimination, a new study led by Boston University …
Retina Transplantation Improved By Manipulating Recipient Retinal Microenvironment
A research team in the United Kingdom has found that insulin-like growth factor (IGF1) impacts cell transplantation of photoreceptor precursors by manipulating the retinal recipient microenvironment, enabling better migration and integration of the cel…
Hope For Treatment Of Hearing Loss With Usher Syndrome III
A new study published in the July 11 issue of the Journal of Neuroscience details the development of the first mouse model engineered to carry the most common mutation in Usher syndrome III causative gene (Clarin-1) in North America. Further, the resea…
Help For The Blind From Device Converting Images Into Music
Sensory substitution devices (SSDs) use sound or touch to help the visually impaired perceive the visual scene surrounding them. The ideal SSD would assist not only in sensing the environment but also in performing daily activities based on this input….
Debilitating Eyesight Problems Are On The Decline For Older Americans
Today’s senior citizens are reporting fewer visual impairment problems than their counterparts from a generation ago, according to a new Northwestern Medicine study. Improved techniques for cataract surgery and a reduction in the prevalence of macular …
Subjects With Visual Impairment Use ‘Blindsight’ – They Turn Their Eyes Towards Motion, Brightness And Color
The visual information from eyes is sent into the brain unconsciously even if you are not aware. One example of unconscious seeing is a phenomenon called “blindsight” [Subjects have no awareness, but their brains can see] in subjects with visual impair…
Eyesight Problems Reducing Among Older Americans
Older Americans are reporting fewer serious eyesight problems today than they were a generation ago, according to a new study published in the journal Ophthalmology recently. The researchers suggest improvements in healthcare such as cataract surgery…
Research Reveals That The Eyes Give Away More Than We Might Think
Our eyes don’t just take in the world around us, they can also reflect our emotional state, influence our memories, and provide clues about the way we think. Here is some of the latest research from the journals Psychological Science and Current Direct…
Stem Cell Breakthrough Significant For Degenerative Diseases
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 Manufacturin…
Cheaper, Faster Diagnosis In Heterogeneous Disease Via Exome Sequencing
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 Societ…
Why Do Women Need Reading Glasses Sooner Than Men?
