A New Chemical Pathway that Helps the Brain Detect Different Tastes

Until now, many scientists believed that a single protein – TRPM5 – acted as a gatekeeper for tasting these delectable foods. Remove TRPM5 from a person's taste cells, and they would not be able to identify sweet, bitter or savory foods. A new study challenges this thinking. The research, published in the Proceedings of the National Academy of Sciences ( PNAS ), finds that a second protein – TRPM4 – performs a similar role in the taste system.

One HPV type Infection Strongly Increases Risk of Reinfection in Men

A new analysis of genital human papillomavirus (HPV) in men shows that infection with one HPV type strongly increases the risk of reinfection with the same type. In fact, men who are infected with the type responsible for most HPV-related cancers are 20 times more likely to be reinfected within one year. This increased risk suggests that infection confers no natural immunity against HPV, as is often the case with other viruses.

Study Founds Gut Evolutionary Origin

An investigation of the embryonic development of sea anemones, a very old animal lineage, researchers have now come to conclusions which challenge the 150-year-old hypothesis of the homology (common evolutionary origin) of the germ layers that form all later organs and tissues According to a 150-year-old hypothesis, all tissues and organs in our body derive from one of three germ layers that are established during early embryogenesis.

Mild Traumatic Brain injury: Promising treatment with Transcranial Electrical Stimulation

Using a form of low-impulse electrical stimulation to the brain, documented by neuroimaging, researchers at the University of California San Diego School of Medicine, Veterans Affairs San Diego Healthcare System (VASDHS) and collaborators elsewhere, report significantly improved neural function in participants with mild traumatic brain injury (TBI). Their findings are published online in the current issue of the journal Brain Injury.

Correlations between Biomarkers and Alcohol Consumption in Gastric Cancer Patients

A new study published in The American Journal of Pathology reported that expression of DNA repair-related biomarkers (BRF1, BRCA1 / 2, and MPO) affected by alcohol can be linked to anticipated response to chemotherapy and survival of gastric cancer patients. It is the first time that a correlation between a key microRNA-processing modulator, transcription factor IIB-related factor 1 (BRF1), and prognosis of gastric cancer patients has been demonstrated.

Comparison Of Microbial Community On ISS And Homes On Earth

According to researchers, Microbiologists at the University of California, Davis who analyzed swabs taken by astronauts on the International Space Station (ISS) and compared them with samples from homes on earth as well as the Human Microbiome Project found that the microbial community in this unique habitat was very diverse and more closely resembled that of homes than of humans. This has been published in PeerJ.
