Weill Cornell team discovers how brain's own tPA helps regulate blood flow to neurons
NEW YORK (Jan. 17, 2008) -- The human brain contains its own store of a powerful enzyme (and stroke drug) called tissue plasminogen activator (tPA), which appears to be a key regulator of blood flow to brain cells, a team at the Weill Cornell Medical College in New York City reports.

Carotid artery stenting- questions still remain
A procedure called carotid artery stenting (CAS) has emerged as a minimally invasive alternative to surgery, called carotid endarterectomy (CEA), for patients with dangerous narrowing of the arteries supplying blood to the brain. However, questions remain about the best uses of this procedure—especially whether it is an appropriate alternative to surgery for "low-risk" patients, according to a special article in the January/February issue of Annals of Vascular Surgery.

Amsterdam, The Netherlands, Sept. 19, 2007 -- New research, including two studies presented this week at the 43rd Annual Meeting of the European Association for the Study of Diabetes (EASD), further support the cardiovascular safety of ACTOS (pioglitazone HCI) and its benefits regarding improved blood glucose and blood lipid levels for patients with type 2 diabetes. The unique outcomes, including some clinical practice results, reinforce the consistency of pioglitazone data and underscore that ACTOS has different effects from the other thiazolidinedione rosiglitazone due to differences in molecular structure.

New research discovers independent brain networks control human walking
(Baltimore, MD) - In a study published in the August issue of Nature Neuroscience, researchers at the Kennedy Krieger Institute in Baltimore, Maryland found that there are separate adaptable networks controlling each leg and there are also separate networks controlling leg movements, e.g., forward or backward walking. These findings are contrary to the currently accepted theory that leg movements and adaptations are directed by a single control circuit in the brain. The ability to train the right and left legs independently opens the door to new therapeutic approaches for correcting walking abilities in patients with brain injury (e.g., stroke) and neurological disorders (e.g., cerebral palsy and multiple sclerosis).

Postmenopausal hormone therapy and coronary disease -- the truth of the matter
With each new publication of coronary artery disease (CAD) data from the Women’s Health Initiative (WHI) study, the inevitable reaction is “Why on earth did the WHI investigators claim in 2002–2004 that postmenopausal hormone therapy has deleterious effects on the risk for CAD, when, from the beginning, they were aware of the importance of the age factor in this clinical scenario”. Women in the age group of 50–59 years who participated in the estrogen-alone arm of the WHI study were asked immediately after the early cessation of the trial to become part of an ancillary study – the WHI-CACS – which looked at the magnitude of coronary calcifications measured by ultra-fast coronary CT. Coronary calcium deposits develop as part of the atherosclerosis process and correlate well with findings of coronary angiography.

New clues to stroke role in Alzheimer's
Researchers have discovered key details of how stroke or traumatic brain injury can trigger Alzheimer’s disease (AD) by enhancing formation of brain-clogging amyloid plaques. Their experiments established that “executioner” enzymes that kill brain cells during stroke or head trauma also interfere with the normal disposal of an enzyme that helps generate plaque. This interference increases the level of the enzyme in brain cells, they found.

Carnegie Mellon University research shows how sensory-deprived brain compensates

These stiff hairs relay sensory input to the brain, which shapes neuronal activity. In a first, studies of this system by Carnegie Mellon scientists show just how well a mouse brain can compensate when limited to sensing the world through one whisker. Published April 4 in the Journal of Neuroscience, the results should help shape future studies of sensory deprivation that results from stroke or traumatic brain injury, say the authors.

Hypertension experts clash over TROPHY study results
When the results of a major long-term, multicenter study, the Trial of Preventing Hypertension (TROPHY), were called into question in two editorials published in the November 2006 issue of the American Journal of Hypertension (AJH), it was inevitable that an exchange of views between the study's supporters and detractors would occur. The essential issue is whether the TROPHY data support the conclusions reported in the New England Journal of Medicine. The March issue of the American Journal of Hypertension publishes a response from TROPHY study investigators Stevo Julius, MD, ScD, Brent M. Egan, MD, and M. Anthony Schork, PhD, defending the work, while authors of the original AJH editorials, Dr. Stephen Persell, Dr. David W. Baker and Dr. Jay I.
