Gut bacteria regulate nerve fibre insulation

Research suggests that gut bacteria may directly affect brain structure and function, offering new ways to treat multiple sclerosis and psychiatric conditions

Far from being silent partners that merely help to digest food, the bacteria in your gut may also be exerting subtle influences on your thoughts, moods, and behaviour. And according to a new study from researchers at University College Cork, your gut microbes might affect the structure and function of the brain in a more direct way, by regulating myelination, the process by which nerve fibres are insulated so that they can conduct impulses properly.

The surprising new findings, published today in the journal Translational Psychiatry, provide what is perhaps the strongest evidence yet that gut bacteria can have a direct physical effect on the brain, and suggest that it may one day be possible to treat debilitating demyelinating diseases such as multiple sclerosis, and even psychiatric disorders, by altering the composition of the gut’s microbial menagerie in some way or another.

3. The Informant alleged that OP-2 is the sole producer of VSF having a market share of almost 100% in India and it is misusing its sole position in the domestic market to squeeze the textile industry consumers. With regard to OP-3 and OP-4, it was alleged that OP-2 imports and markets its products and Case No. 62 of 2016 2 Public Version OP-3, operating from Thailand and OP-4, operating from Indonesia, have joined hands to exploit the Indian market.

Fibres from polyester clothes could be more damaging to marine life than microbeads

Tiny polyester fibres, which are washed into rivers, lakes and seas every time we do our laundry could cause more harm to animals than plastic microbeads, finds a new study. The researchers looked at the effect of microbeads and fibres on a small crustacean called Ceriodaphnia dubia, which lives in freshwater lakes. They found that although both types of plastic were toxic, microfibres caused more harm. Both microplastics stunted the growth of the animals, and reduced their ability to have offspring; microfibres, however, did this to a greater degree, and also caused noticeable deformities in the crustacean’s body and antennae.

Manufacturing method of medical textiles woven from chitosan containing high wet modulus rayon fibre

An anti-“Methicillin-Resistant Staphylococcus Aureus (MRSA)” chitosan containing antibacterial High Wet Modulus (HWM) rayon fiber textile for medical usage is made of the steps as following: chitin flakes made from natural shrimp or crab shells are deacetylated to generate chitosan with a high deacetylation degree of 90% or more. Next chitosan is dissolved in acetic acid and regenerated by caustic soda to form a chitosan antibacterial nanoparticles slurry, then added to HWM viscose rayon process, and spinning to produce a chitosan containing antibacterial HWM rayon fiber. The antibacterial amino groups of chitosan and the hydroxyl groups of rayon cellulose combine together via hydrogen bonding.
