Study examines treatment to maintain blood pressure in those with disorder causing postural drops

Use of a medication called pyridostigmine alone or in combination with low-dose midodrine appears to improve standing blood pressure in patients with orthostatic hypotension, a fall in blood pressure associated with postural changes and standing

Major Alzheimer's discovery

A team from the Faculty of Medicine at Universiti Laval and the research centre at CHUQ (Centre hospitalier universitaire de Quibec) has discovered a natural defence mechanism that the body deploys to combat nerve cell degeneration observed in persons with Alzheimer's disease (AD).

Genome data may contain small but significant errors

Since the genome sequence of the bacterial pathogen Haemophilus influenzae was published in 1995, the genetic code of many other large, complex, medically, and commercially significant organisms including humans has also been elucidated

Science is bypassing poor people

Applying science and technology to build a Pluto-bound spacecraft that travels more than 10 times faster -- 47,000 miles per hour -- than a speeding bullet is a great achievement. But can we apply technology to feed the 800 million hungry people in the world whose plight isn't improving in a modern world?
