Possible link between norovirus and food allergies

Researchers at the Medical College of Wisconsin have found a possible link between norovirus, a virus that causes "stomach flu" in humans, and food allergies.

New clues about connections among fat, inflammation and insulin resistance

In a new study, scientists report that they substantially curbed weight gain, improved metabolism, and improved the efficacy of insulin in mice by engineering them to express a specific human enzyme in their fat tissue. Although the obesity prevention came at the significant cost of widespread inflammation, the research offers new clues about the connections among obesity, insulin resistance and type 2 diabetes, and inflammation.

New project to identify what gives biosonar the edge over human-made technologies

Sonar and ultrasound, which use sound as a navigational device and to paint accurate pictures of an environment, are the basis of countless technologies, including medical ultrasound machines and submarine navigation systems. But when it comes to more accurate sonar and ultrasound, animals' "biosonar" capabilities still have the human race beat.

Fetal stem cells play an important role in inducing maternal cardiac repair

Researchers from Mount Sinai School of Medicine have discovered the therapeutic benefit of fetal stem cells in helping the maternal heart recover after heart attack or other injury.

Lower glycemic index diet may delay onset of AMD-like lesions

Feeding older mice a lower glycemic index (GI) diet consisting of slowly-digested carbohydrates delays the onset of age-related, sight-threatening retinal lesions, according to a new study from the Laboratory for Nutrition and Vision Research at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University.

Cultured ES cells can self-organize into three-dimensional tissue-like structures

The possibility that functional, three-dimensional tissues and organs may be derived from pluripotent cells, such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), represents one of the grand challenges of stem cell research, but is also one of the fundamental goals of the emerging field of regenerative medicine.

Stem cell bandage human clinical trial for torn meniscal cartilage

The company behind a pioneering stem cell bandage, believed to be the world's first adult and autologous (patient's own) stem cell treatment designed to heal torn meniscal cartilage, can now take the technology to human clinical trials thanks to an investment from one of the UK's most successful entrepreneurs.

Bone-marrow derived cells do not improve heart function after attack

NIH-funded trial shows that therapy with bone-marrow derived cells does not improve heart function after six months; future clinical benefits still possible.

Top-line results from Probiodrug's PQ912 Phase 1 SAD, MAD study for Alzheimer's disease

Probiodrug AG, a biotech company developing products for the treatment of neurodegenerative and inflammatory diseases, with a particular focus on Alzheimer's disease (AD), today announced top-line results of its Phase 1 single (SAD) and multiple ascending dose (MAD) study of PQ912 in healthy volunteers.

Global demand to join pioneering adult stem cell study to treat ALS

BrainStorm Cell Therapeutics Inc., an innovative developer of adult stem cell technologies and CNS therapeutics, today announced that patients from across the globe are demanding to be included in the pioneering clinical study started earlier this year at Jerusalem's Hadassah University Medical Center.

New Allen Mouse Brain Connectivity Atlas

The Allen Institute for Brain Science announced today the launch of a new brain atlas resource and updates to four existing resources, all publicly available online to accelerate brain research around the globe.

New insight into how the human brain learns and remembers

New research released today provides insight into one of neuroscience's most intriguing mysteries: how the human brain learns and remembers. These studies - involving topics as diverse as musical memory, "change blindness," and attention deficit hyperactivity disorder (ADHD) - illustrate the profound influence that specific changes in either the brain's structure, function, or both, can have on human behavior.

Luminescent upconversion nanocrystals can detect cancer cells

Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Opaque tissues can be turned into glassy, transparent substances by using these biomarkers which rely on near-infrared excitation.

Occupational chemical exposure raises for Parkinson's

A new research report contributes to the increasing evidence that repeated occupational exposure to certain chemical solvents raises the risk for Parkinson's disease. Researchers analyzed the occupational histories of twins in which one of the pair developed the neurodegenerative disorder, and assessed that twin's likelihood of exposure to six chemicals previously linked to Parkinson's.

Scientists discover molecular basis for tamoxifen resistance and potential way to defeat it

In the last three decades, thousands of women with breast cancer have taken the drug tamoxifen, only to discover that the therapy doesn't work, either because their tumors do not respond to the treatment at all, or because they develop resistance to it over time. Now researchers at the University of California, San Francisco (UCSF) have discovered the molecular basis for tamoxifen resistance and found a potential way to defeat it.

Scientists create new phenotypic cancer drug screening platform

Researchers have created a new phenotypic screening platform that better predicts success of drugs developed to prevent blood vessel tumor growth when moving out of the lab and onto actual tumors.

Scientists identify factors that lead to concomitant tumor resistance

Scientists are another step closer to understanding what drives tumor metastasis, as laboratory models suggest there are factors inside tumors that can slow their own growth.

Next-generation drugs may prevent skin lesions in BRAF mutation-positive melanoma

Findings from preclinical studies in a skin cancer model showed that next-generation BRAF inhibitors used alone, or first-generation BRAF inhibitors used in combination with an epidermal growth factor receptor inhibitor, may have the potential to prevent drug-induced skin lesions in BRAF mutation-positive patients treated for melanoma.

ZIOPHARM announces darinaparsin preclinical data on prostate cancer

ZIOPHARM Oncology, Inc., a drug development company employing small molecule and synthetic biology approaches to cancer therapy, announced today that results from preclinical studies of darinaparsin (Zinapar or ZIO-101), a novel organic arsenic, in prostate cancer were presented at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, taking place November 12-16 in San Francisco.

Combination of REGN910 and aflibercept inhibits tumor angiogenesis in animal models

Combining the investigational agents REGN910 and aflibercept yielded statistically significant improvements in antitumor effects in animal models compared with either agent alone, according to results presented at the AACR-NCI-EORTC International Conference: Molecular Targets and Cancer Therapeutics, held Nov. 12-16, 2011.
