Regular exercise reduces development of painful diabetic neuropathy in animals

Regular exercise reduces the development of painful diabetic neuropathy in animals—apparently related to increased expression of a protective substance called "heat shock protein" 72 (Hsp72), reports an experimental study in the February issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

MammaPrint breast cancer test can help women avoid chemotherapy

The MammaPrint breast cancer test can dramatically reduce the number of women who need to undergo chemotherapy to treat the disease, according to a newly published study.

DCC receptor plays key role in regulating brain plasticity

Our ability to learn and form new memories is fully dependent on the brain's ability to be plastic - that is to change and adapt according to new experiences and environments. A new study from the Montreal Neurological Institute - The Neuro, McGill University, reveals that DCC, the receptor for a crucial protein in the nervous system known as netrin, plays a key role in regulating the plasticity of nerve cell connections in the brain.

Orphan, St George's sign licensing agreement to develop new therapies for metabolic disorders

St George's, University of London has signed an exclusive worldwide licensing agreement with rare-disease research-and-development firm Orphan Technologies Ltd to develop new therapies for deadly metabolic disorders.

UPCI researchers uncover new technique to stop growth of cancer cells

University of Pittsburgh Cancer Institute (UPCI) researchers have uncovered a technique to halt the growth of cancer cells, a discovery that led them to a potential new anti-cancer therapy.

Presenilin-1 gene plays central role in development of neuronal histamine system

Researchers at University of Helsinki, Finland, have shown in a study conducted on zebrafish, that the presenilin-1 (psen1) gene associated with Alzheimer's disease functions as a central regulator for the development of the histamine system. Histamine system is also altered in patients suffering from Alzheimer's disease.

NSU-COM to hold grand opening for America's first Institute for Neuro Immune Medicine

Nova Southeastern University's College of Osteopathic Medicine (NSU-COM) will hold a grand opening for America's first Institute for Neuro Immune Medicine on Feb. 12.

Nitric oxide shuts down brain's repair mechanisms

Nitric oxide, a gaseous molecule produced in the brain, can damage neurons. When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer's. Researchers at Sanford-Burnham Medical Research Institute recently discovered that nitric oxide not only damages neurons, it also shuts down the brain's repair mechanisms.

PET with 11C-PIB can positively visualize amyloid deposits in the heart

While amyloid imaging may now be most associated with detecting plaques in the brain, it has the potential to change the way cardiac amyloidosis is diagnosed. According to first-of-its-kind research published in the February issue of The Journal of Nuclear Medicine, positron emission tomography (PET) with 11C-PIB can positively visualize amyloid deposits in the heart.

New gold nanoparticle can transport powerful radioactive particles directly to tumors

We've all heard that "it's not wise to use a cannon to kill a mosquito." But what if you could focus the cannon's power to concentrate power into a tiny space? In a new study, University of Missouri researchers have demonstrated the ability to harness powerful radioactive particles and direct them toward small cancer tumors while doing negligible damage to healthy organs and tissues.

Scientists identify specific cellular events that appear key to lupus

A team led by scientists at The Scripps Research Institute (TSRI) has identified specific cellular events that appear key to lupus, a debilitating autoimmune disease that afflicts tens of millions of people worldwide. The findings suggest that blocking this pathway in lupus-triggering cells could be a potent weapon against the disease.

Accumulation of passenger mutations can slow or even halt tumor growth

A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression.

Amygdala not the only gatekeeper of fear in human mind

When doctors at the University of Iowa prepared a patient to inhale a panic-inducing dose of carbon dioxide, she was fearless. But within seconds of breathing in the mixture, she cried for help, overwhelmed by the sensation that she was suffocating.

Immune system can use melanoma's own proteins to kill off cancer cells

Though a small group of proteins, the family called Ras controls a large number of cellular functions, including cell growth, differentiation, and survival. And because the protein has a hand in cellular division, mutated Ras, which can be detected in one-third of all tumors, contributes to many human cancers by allowing for the rapid growth of diseased cells.

AIBioTech announces implementation of L-asparaginase activity assay for pediatric ALL

AIBioTech is pleased to announce implementation of a new laboratory derived test to measure L-asparaginase levels in patients being treated with any of the current asparaginase drugs including: Oncaspar, Kidrolase, Erwinaze, and Elspar.

Researchers identify gene variants that influence lifespan

By broadly comparing the DNA of children to that of elderly people, gene researchers have identified gene variants that influence lifespan, either by raising disease risk or by providing protection from disease.

GVK Biosciences extends GOBIOM license to Biomarker Qualification Group of US FDA

GVK Biosciences (GVK BIO) today announced that it is extending its Clinical Biomarker Database (GOBIOM) license to the Biomarker Qualification Group of the US Food and Drug Administration (US FDA).

New method for detecting cancer by measuring elasticity of tumours

As the first countries in the world, Norway and France will be testing a completely new method for detecting cancer. This is done by measuring the elasticity of tumours. The method is called elastography. You may as well learn this new word right away; in a few years, elastography may be as common as X-rays.

Hope against dangerous form of acute lymphoblastic leukemia

After an intensive three-year hunt through the genome, medical researchers have pinpointed mutations that leads to drug resistance and relapse in the most common type of childhood cancer-the first time anyone has linked the disease's reemergence to specific genetic anomalies.

Researchers discover gene that causes MRSA infection to linger on skin longer than other strains

In the last decade, a new strain of MRSA has emerged that can spread beyond hospital walls, putting everyone at risk of contracting the dangerous bacterial infection. This particular strain of MRSA - known as USA300 - contains a chunk of genes not shared by any other strains, though it is unclear how this unique genetic material enables the bacteria to survive and persist in the community.
