Morphophysiological Of Human Brain Cell

Scientists have uncovered a new type of human brain cell that has never been seen in mice and other well-studied laboratory animals. They are really can't understand the specialty of the human brain. Studying the differences at the level of cells and circuits is a good place to start, and now we have new tools to do just that. The study was published in the journal Nature Neuroscience.

Light-Emitting Nanoparticles Used To See Deep In Living Tissue

Researchers have demonstrated how light-emitting nanoparticles, it can be used to see deep in living tissue. The specially designed nanoparticles can be excited by ultralow-power laser light at near-infrared wavelengths considered safe for the human body.

They absorb this light and then emit visible light that can be measured by standard imaging equipment. The development and biological imaging application of these nanoparticles is detailed in a study published online in Nature Communications.

 

Visualizing Human Cochlea Using Contrast Imaging

The researcher showed the interest in providing people who suffer from sensorineural hearing loss with a richer music-listening experience has led a young Harvard researcher to the Canadian Light Source (CLS) and to a discovery that opens the door to exciting new avenues for the study and diagnosis of human inner ear diseases. The study was published in the journal Biomedical Optics Express.

Itchy Skin Could Be Warning Sign Of Diabetes

Diabetes symptoms include frequent urination and unexplained weight loss, but itchy skin could also be an early warning sign. Diabetes is a lifelong condition that causes a person's blood sugar level to become too high.

Most people with type-1 diabetes are born with the condition, while type-2 can come on at any time. Type-2 diabetes develops when the body becomes resistant to insulin or when the pancreas stops producing enough insulin.

Type-2 Diabetes

Common type-2 diabetes symptoms include frequent urination, a sudden increase in appetite, moods swings and problems sleeping. But there are some other ways to spot the early warning signs of the disease.

Immunotherapy Combination With Pembrolizumab In Advanced Melanoma

The researcher has found that a treatment that uses a bacteria-like agent in combination with an immunotherapy drug could help some people with advanced melanoma, an aggressive form of skin cancer, live longer.

The research showed that using the immunotherapy drug pembrolizumab and the experimental agent SD-101, a sequence of nucleic acids that mimics a bacterial infection, altered the microenvironment around the tumor in a way that enabled the immune system to more effectively attack cancer. 

The research was an early-stage study, conducted to test the side effects and best dosage of a potential new combined therapy. The study was published in the journal Cancer Discovery.

Surveillance And Autopsy Characterization of Sudden Cardiac Death

Researchers identified all incident deaths attributed to out-of-hospital cardiac arrest (patients between 18 and 90 years of age in San Francisco County) based on autopsy, toxicology, and histology via medical examiner surveillance of consecutive out-of-hospital deaths.

A large percentage of deaths attributed to cardiac arrest is neither sudden nor unexpected. Deaths were assessed using the World Health Organization (WHO) criteria for sudden cardiac death(SCD), and the death certificates were reviewed for missed cases of SCD. The study was published in Circulation.

Astronauts Trying To Find Better Cancer Treatments In Space

With careful attention from an astronaut, a blood cell experiment may deliver improvements on cancer-fighting treatments. There's a lot of blood in space right now to be exact, there are a lot of endothelial cells that come from blood vessels.

Astronauts are helping study these cells aboard the International Space Station (ISS) as part of the Angiex Cancer Therapy trials, which NASA astronaut Serena Auñón-Chancellor introduced in a new video. The study was published in NASA.
