Optic-Nerve Stimulation For the Blind

eye-brain-connection

A recent article published last month (August 19, 2019) in Nature1 reports a potential way to aid the blind by stimulating the optic nerve. The researchers placed an intraneural electrode array intraneurally to directly induce distinct electrical stimulation to the optic nerve, recording patterns via an electrocorticography (ECoG) array. Previous studies2 on stimulating the optic nerve did not yield conclusive ... Read More »

Culturally Adapted Diabetes Intervention in Sikh Indians in NYC

Culturally-Adapted-Diabetes-Intervention-in-Sikh-Indians-in-NYC

Researchers at NYU School of Medicine evaluated worsening diabetes trends in Sikh Indians, the largest South Asian Subgroup in NYC¹. The purpose of their study was to find a general diabetes prevention method that targeted specific Asian groups: weight, BMI, and blood pressure. The methods included using community health workers to lead six intervention classes with 10 follow-up phone calls ... Read More »

Major differences in cardiovascular risk profiles in Chinese Australians as compared to non-Chinese

Chinese Australians have lower cardiovascular disease and stroke incidence as compared with non-Chinese Australians. However, they have worse cardiovascular risk profiles, including a higher prevalence of diabetes, smoking, and a lower exercise level. Furthermore, mixed-Chinese populations have even worse cardiovascular risk profiles. 1. Marked differences in cardiovascular risk profiles in middle-aged and older Chinese residents: Evidence from a large Australian ... Read More »

long flights to Asia and UV exposure to pilots

Exposure to uv radiation increases approximately 5% for every 1000 feet of altitude. Both infrared (IR) and ultraviolet (uv) radiation are present in our environment, depending on the time of day, year, latitude, altitude and weather conditions and reflectivity of the surrounding surfaces, the pilot will receive more or less radiation. uv-a (400 – 315 nm), uv-B (315 – 280 ...

photoreceptor ganglion cells and vision

New research shows that in our retina, we have “photoreceptor ganglion cell” which responds to light at 480 nanometer wavelength. This wavelength causes abnormal sleep cycle. But this same cell allows previous blind people to SEE!   In the latest research, they took people born with abnormal eyes and thought to be blind and found they could see when exposed ...

Dr Masayo Takahashi and retinal cell transplant into 70 year old patient

In September 2014, Dr. Masayo Takahashi and her colleagues at the RIKEN Center for Developmental Biology used iPS cells (induced pluripotent stem cells) to treat age related macular degeneration. They used skin cells from the patient and “reprogrammed” that cell line into becoming adult retinal cells. These were transplanted into the patient’s eye in a two hour procedure. Her vision ...
