Borrelia burgdorferi peptidoglycan is a persistent antigen in patients with Lyme arthritis [Immunology and Inflammation]
Lyme disease is a multisystem disorder caused by the spirochete Borrelia burgdorferi. A common late-stage complication of this disease is oligoarticular arthritis, often involving the knee. In ∼10% of cases, arthritis persists after appropriate antibiotic treatment, leading to a proliferative synovitis typical of chronic inflammatory arthritides. Here, we provide evidence…

It's a Winner-Take-All World, Whether You Like It or Not
Not long ago, I reached out to a writer I respect, and posed the uncomfortable question authors find themselves forced to ask: Would she write a blurb—the endorsement you see on the back cover—for my new book about how a person can navigate a career in the winner-take-all economy of the 21st century? She declined. She felt strongly that this winner-take-all dynamic needs to be fought, not embrace

Harvard chemists' breakthrough in synthesis advances a potent anti-cancer agent
Chemists at Harvard University and Eisai have achieved what a new paper calls a 'landmark in drug discovery' with the total synthesis of 11.5g of halichondrin. Known to be a potent anti-cancer agent in mouse studies, and found naturally in sea sponges — though only ever in minuscule quantities — the halichondrin class of molecule is so fiendishly complex that it had never been synthesized on a m

Hypertension drug may hold promise for Alzheimer's disease
The blood pressure drug nilvadipine increased blood flow to the brain's memory and learning center, without affecting other brain regions among people with Alzheimer's disease.These findings indicate that the known decrease in cerebral blood flow in patients with Alzheimer's can be reversed in some regions.However, it is unclear if this translates to clinical benefits.

Odling av makroalger (tång) används för att ta upp de lösta näringsämnen som fiskar och skaldjur släpper ut. Ett annat sätt är samodling med filtrerande djur som musslor och ostron, vilka tar upp näring i form av små partiklar i vattnet. Kompletterande städpatrull Men även sjögurkor kan bidra ti
