Duffy-Negative Blood Types No Longer Protected From Malaria

In a paradigm changing discovery, Plasmodium vivax (P. vivax) malaria has been identified in a population historically thought to be resistant to the disease, those who do not express the Duffy blood group protein on their red blood cells, according to researchers from Case Western Reserve University School of Medicine, Pasteur Institute, and the Madagascar Ministry of Health.

Brain Plaques May Explain Higher Risk of Alzheimer’s Based on Mom’s History New imaging tool could eventually lead to earlier detection among pre-symptomatic individuals

A family history of Alzheimer’s is one of the biggest risk factors for developing the memory-robbing disease, which affects more than 5 million Americans and is the most common form of senile dementia. Now an international collaboration led by NYU Langone Medical Center researchers has found the likely basis for this heightened familial risk—especially from the maternal side.

Scientists Demonstrate Mammalian Regeneration Through a Single Gene Deletion

A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution and reserved for creatures like flatworms, sponges, and some species of salamander. In a report published today in the Proceedings of the National Academy of Sciences, researchers from The Wistar Institute demonstrate that mice that lack the p21 gene gain the ability to regenerate lost or damaged tissue.

Researchers Identify Gene that May Play Role in Atherosclerosis

A new study suggests that a gene called HuR plays a critical role in inducing and mediating an inflammatory response in cells experiencing mechanical and chemical stresses. The finding may lead to new treatments for diseases associated with inflammation, such as atherosclerosis.

Drop in Medical Care for Chickenpox Since Vaccine was Introduced: Especially in Children, Doctor Visits and Hospital Stays Have Decreased

Since the varicella vaccine was introduced in the mid-1990s, the number of patients receiving medical care for chickenpox in the United States has decreased sharply—particularly among children, according to a study in the March issue of The Pediatric Infectious Disease Journal (http://www.pidj.com). The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health, a leading provider of information and business intelligence for students, professionals, and institutions in medicine, nursing, allied health, and pharmacy.

Global Research Technologies and Columbia University Enter Into Carbon Dioxide Air Capture Research and Licensing Collaboration

New York, NY - Columbia University and Global Research Technologies (GRT) announced that they have entered into a worldwide research collaboration and cross-licensing agreement for technology that extracts and captures carbon dioxide (CO2) from the atmosphere.
