Scientists restore hearing in noise-deafened mice, pointing way to new therapies

Scientists have restored the hearing of mice partly deafened by noise, using advanced tools to boost the production of a key protein in their ears. By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research in humans that could improve treatment of hearing loss caused by noise exposure and normal aging.

Analysts see U.S. approval of Novo Nordisk’s obesity drug by year-end

COPENHAGEN (Reuters) – The U.S. Food and Drug Administration is likely to approve Novo Nordisk’s new drug to treat obesity this year, analysts said after wide expectations of an FDA decision late on Monday were not met. Danish drugmaker Novo Nordisk applied for approval for liraglutide, under the name of Saxenda, on Dec. 20 last year. Monday, exactly 10 months after the filing, was seen by analysts as a deadline for a decision from FDA about approval. FDA has set a goal to process applications for approvals within 10 months but there are examples when they spend more than that on applications. …

Flu drug aimed at Ebola may also fight norovirus, study finds

LONDON (Reuters) – An experimental Japanese flu drug that has hit the headlines because of its potential to fight Ebola may also work against norovirus, the winter vomiting bug, British researchers said on Tuesday. As with Ebola, the research is still at an early stage but a study in mice found that Fujifilm’s Avigan, or favipiravir, was effective at reducing — and in some cases eliminating — norovirus infection. The drug works by causing the virus to self-destruct in a process known as “lethal mutagenesis”, which causes errors in its genetic information. …
