Basel, 22 May 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) will present new pooled pivotal satralizumab safety results for the treatment of neuromyelitis optica spectrum disorder (NMOSD), a rare, debilitating central nervous system disorder. These data are being presented at the 6th Annual Meeting of the European Academy of Neurology (EAN) and show satralizumab was well-tolerated in a broad patient population – including adolescents, for whom there is no approved medicine. Satralizumab is an investigational humanised monoclonal antibody that targets the interleukin-6 (IL-6) receptor, believed to play a key role in the i...

Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therapeutic effect. Unfortunately, in practice the nutraceutical industry is a largely a lazy one, in which entrepreneurs take advantage of a short path to market, and a lack of interest among consumers in whether or not products actually work, in order to repackage cheap ingredients into expensive brands that have minimal, unreliable, or even...

In this study, we found that older nematodes have higher ROS levels. Interestingly, after hydrogen treatment, the ROS levels were significantly decreased, and hydrogen could significantly extend the lifespans of the N2, sod-3 and sod-5 mutant strains, by approximately 22.7%, 9.5%, and 8.7%, respectively. In addition, aging is regulated by a variety of pathways, such as the insulin signaling pathway, the rapamycin target signaling pathway, and the caloric restriction pathway. However, our results showed that the lifespans of the daf-2 and daf-16 strains, in which these pathways are upregulated, were not affected afte...

Abstract Changes in protein structure and function, alteration in protein-protein interaction, and significant difference in protein concentration inside the body could play an important role in indicating the pathological evidence of abnormalities before the development of clinical symptoms and act as a critical detection and diagnostic tool commonly known as biomarkers. Biomarkers play important roles in the diagnosis of various chronic diseases including cancer. Neurodegenerative disorders including Parkinson's, Alzheimer's, Huntington's, prion, and multiple sclerosis are well characterized by neuronal deterior...
