0.6 percent soy isoflavone in the diet decrease muscle atrophy

Jan 18 2018 - 00:01
Scientists at Tokyo Institute of Technology (Tokyo Tech) have discovered a means of reducing muscle atrophy by the addition of the soy-derived isoflavone aglycone (AglyMax) to the diet of mice. This attenuation by soy isoflavone is attributable to block the apoptosis-dependent pathway in muscle fiber. The AglyMax supplement also anticipate to attenuate age-related muscle loss, sarcopenia.

Efficacy of antibody targeting Devic's disease proven in new animal model

Jan 18 2018 - 00:01
Neuromyelitis optica (NMO) is an autoimmune disease associated with NMO immunoglobulin G (NMO-IgG). A cure for NMO remains elusive. Osaka University researchers recently established a localized NMO rat model by injecting NMO-IgG into the spinal cord, and 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.

Cellular mechanism for severe viral hepatitis identified

Jan 18 2018 - 00:01
KAIST medical scientists identified a cellular mechanism causing inflammatory changes in regulatory T cells that can lead to severe viral hepatitis. Research on this mechanism will help further understand the nature of various inflammatory diseases and lead to the development of relevant clinical treatments.

Why some of your old work commitments never seem to go away

Jan 18 2018 - 00:01
You can quit work commitments if you want - but some of them never really leave you, new research suggests. In a study of 420 employees representing a wide variety of occupations and work settings at three organizations, researchers found that commitments that workers no longer had were still lingering in their minds.

Lifespan of fuel cells maximized using small amount of metals

Jan 17 2018 - 00:01
KAIST researchers described a new technique to improve chemical stability of electrode materials which can extend the lifespan by employing a very little amount of metals. Using computational chemistry and experimental data, the team observed that local compressive states around the Sr atoms in a perovskite electrode lattice weakened the Sr-O bond strength, which in turn promote strontium segregation.

Slower walking speed in the elderly may be explained by loss of muscle strength and mass

Jan 17 2018 - 00:01
Research recently published in The Journal of Physiology has found that elderly people walk at a slower speed and tire more quickly because of loss of strength and mass in leg muscles. Using computer simulations they found that these physiological changes explain the slower walking speed preferred by the elderly, and that a focus on building up these leg muscles may be the only effective way to improve elderly walking.
