Alaska Scientists Say Salmon Declines Inevitable
...h being done at the University of Alaska Fairbanks suggests
the changes in fish and shellfish abundance, called regime shifts, occur about every 20 years. It's been about that long since Alaska's salmon stocks rebounded from historic lows. Adkison says a regime shift might be under way, but it's still too ear...

that, in human platelets, PAR1 and PAR4 also actas a dual-receptor system. And this suggestion opens up the possibility ofdesigning drugs tailored to this system, said Coughlin. "It may be necessary to block both PAR1 and PAR4 in human platelets to...

that it might be attractive to search for small molecules that may act as surrogate GAPs in tumor cells where Ras is fatally mutated or its GTP-bound levels are increased for other reasons, e.g. due to a missing neurofibromin function. Th...
