Paper-based Test to Diagnose TB

In a new study reported in the ACS Sensors, scientists have developed a colourimetric sensing strategy employing gold nanoparticles and a paper-based analytical platform for the diagnosis of tuberculosis (TB). By utilizing the surface plasmon resonance effect, they were able to monitor changes in the colour of a gold nanoparticle colloid based on the effects of single-stranded DNA probe molecules hybridizing with targeted double-stranded TB DNA.

A New Way To Rejuvenate Inactive Old Cells; Study Found

Research team led by Professor Lorna Harries, Professor of Molecular Genetics at the University of Exeter, has revealed a new way to rejuvenate inactive senescent cells. Within hours of treatment the older cells started to divide, and had longer telomeres, the 'caps' on the chromosomes which shorten as we age. The study published in the journal, BMC Cell Biology.

Antibody Alleviates Symptoms in a Rat Model of Neuromyelitis Optica

Neuromyelitis optica (NMO) is an autoimmune disease associated with NMO immunoglobulin G (NMO-IgG). A cure for NMO remains elusive. Researchers recently assessed the efficacy of anti-repulsive guidance molecule-a (RGMa) antibody in treating NMO. They found anti-RGMa antibody delayed the onset and attenuated the severity of clinical symptoms of NMO, suggesting that humanized anti-RGMa antibody is a potentially valid therapeutic approach for NMO.
