Vanderbilt investigators report new insights into workings of calprotectin

On the front lines of our defenses against bacteria is the protein calprotectin, which "starves" invading pathogens of metal nutrients. Vanderbilt investigators now report new insights to the workings of calprotectin - including a detailed structural view of how it binds the metal manganese.

People with increased genetic risk of schizophrenia more likely to have lower IQs at age 70

People who are at greater genetic risk of schizophrenia are more likely to see a fall in IQ as they age, even if they do not develop the condition. Scientists at the University of Edinburgh say the findings could lead to new research into how different genes for schizophrenia affect brain function over time.

Researchers identify second B-cell attachment receptor for Epstein-Barr virus

Epstein-Barr virus (EBV) affects more than 90 percent of the population worldwide and was the first human virus found to be associated with cancer. Now, researchers from Beth Israel Deaconess Medical Center (BIDMC) have broadened the understanding of this widespread infection with their discovery of a second B-cell attachment receptor for EBV.

Researchers use familial and sporadic patient-derived iPSCs to model Alzheimer's disease

Working with a group from Nagasaki University, a research group at the Center for iPS Cell Research and Application (CiRA) at Japan's Kyoto University has announced in the Feb. 21 online publication of Cell Stem Cell has successfully modeled Alzheimer's disease (AD) using both familial and sporadic patient-derived induced pluripotent stem cells (iPSCs), and revealed stress phenotypes and differential drug responsiveness associated with intracellular amyloid beta oligomers in AD neurons and astrocytes.

Memorial Sloan-Kettering scientist wins Breakthrough Prize in Life Sciences

Charles L. Sawyers, Chair of Memorial Sloan-Kettering's Human Oncology and Pathogenesis Program (HOPP), was awarded the Breakthrough Prize in Life Sciences today. The award - established by Art Levinson, Sergey Brin, Anne Wojcicki, Mark Zuckerberg, Priscilla Chan, and Yuri Milner - recognizes "excellence in research aimed at curing intractable diseases and extending human life."

Two new non-invasive technologies can improve early identification of tumor response to therapy

The research was published early in the January issue of the journal Technology in Cancer Research and Treatment. The article describes experiments using ultrasonic molecular imaging (USMI) and Dynamic Contrast Enhanced-Perfusion Imaging (DCE-PI) to measure response to therapy for pancreatic cancer.

Imatinib can relieve and slow down progression of multiple sclerosis

A drug that is currently used for cancer can relieve and slow down the progression of the autoimmune disease multiple sclerosis (MS) in rats, according to a new study published in PLOS ONE.

Microbubble-ultrasound method improves cardiac output after heart attack

Scientists from the Bonn University Hospital successfully tested a method in mice allowing the morphological and functional sequelae of a myocardial infarction to be reduced. Tiny gas bubbles are made to oscillate within the heart via focused ultrasound - this improves microcirculation and decreases the size of the scar tissue. The results show that the mice, following myocardial infarction, have improved cardiac output as a result of this method, as compared to untreated animals.

Study looks at natural history of cervical spondylolisthesis

Follow-up data on patients with degenerative disease of the upper (cervical) spinal vertebrae show little or no evidence of worsening degeneration over time, according to a study in the February 15 issue of Spine.

Omega-3 emulsions can decrease brain tissue damage following stroke

Triglyceride lipid emulsions rich in an omega-3 fatty acid injected within a few hours of an ischemic stroke can decrease the amount of damaged brain tissue by 50 percent or more in mice, reports a new study by researchers at Columbia University Medical Center.

Daclatasvir has two primary modes of action against HCV

A study by researchers from Los Alamos National Laboratory and a multinational team reveals how daclatasvir, a direct-acting antiviral agent in development for the treatment of hepatitis C virus (HCV), targets one of its proteins and causes the fastest viral decline ever seen with anti-HCV drugs - within 12 hours of treatment.

Gesture helps children with early brain injury learn linguistic connections

Children with brain lesions suffered before or around the time of birth are able to use gestures - an important aspect of the language learning process- to convey simple sentences, a Georgia State University researcher has found.

Ultrathin nanowire-based electrode helps capture signals from brain nerve cells

Electrodes operated into the brain are today used in research and to treat diseases such as Parkinson's. However, their use has been limited by their size. At Lund University in Sweden, researchers have, for the first time, succeeded in implanting an ultrathin nanowire-based electrode and capturing signals from the nerve cells in the brain of a laboratory animal.
