Blood clotting capabilities were tested on another group of mice missing the gene for the leptin receptor, which also made them leptin deficient.

Clotting Protein plays a role in nerve repair

...ated much more rapidly in fibrin-free mice than in normal mice. Strickland's team describes fibrin's role in the repair process--at least outside the brain and spinal cord. After a nerve injury, it seems that a protein called fibrinogen can leak from the blood into the damaged nerve. Once in the nerve, fib...

High Altitude ‘Speeds up ageing process

...A number of hormone systems change with age, under normal circumstances, including DHEA and DHEAS, testosterone in men and growth hormones in both sexes. “Maybe the decline in one of these three hormone levels is key to the ageing process and maybe if you reverse it, you might reverse the ageing process.” ...

Elevating Manganese Levels hold back HIV

Further research determined increasing manganese also lowers the activity of HIV's reverse transcriptase, which could block replication of the virus ...

Treatment of antibiotics ineffectual in bronchitis

Since there is a deficit of evidence that low-dose vitamin C is effective in treating bronchitis, we have to assume that azithromycin is ineffective too - according to th...
