For years, physicians have noticed surprising similarities in the factors that seem to trigger attacks in such episodic neurological disorders as migraine and dyskinesia. Common triggers include psychological stress, caffeine or alcohol ingestion, fatigue, hormonal fluctuations and exercise.

A new study shows that a mouse model can be used to investigate how these substances and environmental factors trigger symptomatic attacks. The researchers also identified two drugs that can prevent at

A new and somewhat controversial study published in the August issue of the Journal of Nuclear Medicine suggests that 18F-FDG PET results obtained after the first cycle of treatment can better predict progression-free survival in patients with aggressive non-Hodgkin’s lymphoma (NHL) or Hodgkin’s disease (HD) than PET scans conducted at the end of treatment.

Physicians at the Weill Medical College of Cornell and the New York Presbyterian Hospital in New York reported on 23 patients

In the northeastern corner of Minnesota stand towering groves of red pine trees stretching some 80 feet into the sky.

But these red pine groves could eventually vanish from Minnesota’s Boundary Water Canoe Area if what we usually view as a foe to forests — fire — fails to sweep the terrain occasionally, says a new study from the University of Wisconsin-Madison.

“The big, natural groves of red pine are one of the most unique features of the BWCA. But, because of fire suppres

Industrial fishing poses the biggest threat to life and fin for sharks, dolphins and billfish that inhabit the tropical and northern Pacific Ocean, says a new study forecasting the effects of commercial fishing on ocean ecosystems.

Though not targeted by the fishing industry, some ocean species often get caught unintentionally in nets or lines used to catch tuna and other commercially valuable fish, says a study presented to scientists today, Aug. 5, at the annual meeting of the Ecological

First amphetamine-based long-acting stimulant offers all-day symptom control in children
A research team led by a Massachusetts General Hospital investigator has found that a long-acting form of the stimulant medication Adderall is effective in controlling symptoms of attention-deficit/hyperactivity disorder (ADHD) in children when taken in a single morning dose. The standard form of Adderall, which is made up of several amphetamine-based drugs, is only effective for four hours. This new f

A physical map of the genetic makeup of a mouse – the mouse genome – is 98 percent complete and is being released online by the journal Nature. Researchers at the Genome Sequencing Center at Washington University School of Medicine in St. Louis played a major role in the international effort, as they did in the sequencing and mapping of the human genome.

“The mouse plays a vital role in research on human biology and disease,” says John D. McPherson, Ph.D., associate professor of genetics a
