A 10-year-long study of patients at an institution has indicated that delayed orthostatic hypotension (DOH) is an earlier, milder form of orthostatic hypotension (OH). Study data showed that over a decade follow-up, 54% of patients having DOH progressed to OH and that a 10-year mortality of patients who progressed to OH was 50%, Christopher H.

The research was reported online by Gibbons, MD, of Beth Israel Deaconess Medical Center, Harvard Medical School in Boston, and colleagues in Neurology.

The investigators said the rise in mortality in individuals with DOH was linked to abnormalities in baseline autonomic test outcomes, progression to OH, the presence of diabetes, and an alpha-synucleinopathy development.

According to a report in the Journal of NeuroEngineering and Rehabilitation, a 26-year-old man, who can’t take steps due to an injury five years ago, was able to walk with the help of his brain-power.

This is for the first time ever when a person, who couldn’t walk because of a spinal cord injury (SCI), has firmly operated a non-invasive brain computer interface (BCI) system for over-ground walking in real time. This instance has given a hope for the possibility of developing BCI brain implants to help out SCI people in walking.

According to a study, sleep apnea should not remain untreated as in most of the patients suffering from depression, the cause is sleep apnea. The American Academy of Sleep Medicine reported that obstructive sleep apnea (OSA) is a common sleep disease, which affects at least 25 million adults in the US.

The study found that if sleep apnea remains untreated, then there is a higher risk of other chronic health problems like heart disease, high blood pressure, Type 2 diabetes, stroke and depression.

It has been reported in a new study by environmental scientists at UC Davis that a huge amount of synthetic clothing fibers is there inside some of the fish they caught off the Northern California coast. These fish are consumed by locals.

According to lead researcher Chelsea Rochman of the UC Davis School of Veterinary Medicine, it was found that nearly a quarter of the 64 fish bought at fish markets in Half Moon Bay and Princeton and examined for the study consisted of pieces of synthetic clothing in their guts.

According to reports, scientists have found that liquid crystals defects could be used as templates for assembling molecules into accurately defined 3-D nanoscale structures. Their work has been published in the September 21 edition of the journal Nature Materials.

According to Nicholas Abbott, the John T. and Magdalen L. Sobota Professor and Hilldale Professor of chemical and biological engineering at the University of Wisconsin-Madison, "It's a demonstration of principle. What one can imagine is using defects in liquid crystals to assemble molecules into a range of useful structures, including channels that could facilitate the transport of other molecules, like nanoscopic tubes”.

Previous week, dead Walrus carcasses were discovered on a northwest Alaska beach, and according to the US Fish and Wildlife Service (FWS), their deaths seemed to be natural. They were found near Point Lay, the same place where 35,000 walrus were spotted on shore September 2.

In a press release on Thursday, the agency said that an employee of the US Geological Survey gave an image of the walrus carcasses. The service mentioned that it has been analyzing the photo to find out whether the carcasses were new or old, and attempting to determine an age range of the walruses. After it, an investigator will have to give a confirmation onsite.
