Researchers find new drug to treat circadian rhythm disorders

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Medical Research Council (MRC) have successfully used a drug to reset and restart the natural 24 hour body clock of mice in the lab. The ability to do this in a mammal opens up the possibility of dealing with a range of human difficulties including some psychiatric disorders, jet lag and the health impacts of shift work.

WHO calls on countries to prevent, control spread of antibiotic resistant bacteria

Amid the growing threat of antimicrobial resistance, the WHO on Friday urged countries to take greater action to limit the spread of drug-resistant bacteria, CIDRAP News reports. "Calling such pathogens 'a growing and global public health problem,' the WHO said, 'Countries should be prepared to implement hospital infection control measures to limit the spread of multi-drug resistant strains and to reinforce national policy on prudent use of antibiotics, reducing the generation of antibiotic resistant bacteria,'" according to the news service (Roos, 8/20).

Research finds variation in sex chromosome may cause lupus in men

Genes reside along long chains of DNA called chromosomes. UCLA researchers have found that a variation in a gene on the sex chromosome X may enhance an immune response that leads to lupus in men.

Alpha-synuclein gene silencing effective for treating neurodegenerative disorders: Research

Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, and collaborators at The Parkinson's Institute and the Mayo Clinic have published new research findings in the journal Public Library of Science (PLoS). The new data show effective silencing of the alpha-synuclein gene with an RNAi therapeutic administered directly to the substantia nigra in the CNS of non-human primates.

Research on fruit fly provides inroads into understanding cancer development

Changes to proteins in a cell underlay many cancers. Rui Martinho at the Instituto Gulbenkian de Ci-ncia (IGC), in Portugal, in collaboration with researchers in Ghent (Belgium) and Bergen (Norway) will use the fruit fly to understand exactly how changes to proteins, identified in the test-tube, impact on the way cells divide in a living organism

Fluid dynamics and mechanics to simulate stent design and coating

Suncica "Sunny" Canic was good at math in school, so that's what she pursued as a career. But she always liked medicine, too. When she moved to Houston, Texas, and met some cardiologists at a party, she started talking with them about what they do-and knew she could help them.

APC dysfunction prevents synapse function required for learning, memory: Study

A clue to the causes of autism and mental retardation lies in the synapse, the tiny intercellular junction that rapidly transfers information from one neuron to the next. According to neuroscientists at Tufts University School of Medicine, with students from the Sackler School of Graduate Biomedical Sciences at Tufts, a protein called APC plays a key role in synapse maturation, and APC dysfunction prevents the synapse function required for typical learning and memory.

Researchers discover unusual property of meiosis may lead to Down syndrome

In a study of egg cells using time-lapse microscopy, researchers at the University of California, San Diego School of Medicine and the Ludwig Institute for Cancer Research have discovered an unusual property of meiosis - cell division that produces reproductive cells in sexually reproducing organisms.

Scientists develop new synthetic material to grow stem cells

Human pluripotent stem cells, which can become any other kind of body cell, hold great potential to treat a wide range of ailments, including Parkinson's disease, multiple sclerosis and spinal cord injuries. However, scientists who work with such cells have had trouble growing large enough quantities to perform experiments - in particular, to be used in human studies. Furthermore, most materials now used to grow human stem cells include cells or proteins that come from mice embryos, which help stimulate stem-cell growth but would likely cause an immune reaction if injected into a human patient.

Researchers find new way to study oncogene's role in DNA repair

A key step in understanding the origins of familial breast cancer has been made by two teams of scientists at the University of California, Davis. The researchers have purified, for the first time, the protein produced by the breast cancer susceptibility gene BRCA2 and used it to study the oncogene's role in DNA repair.

GM-CSF protein reduces AD pathology, reverses memory loss: Study

A signaling protein released during rheumatoid arthritis dramatically reduced Alzheimer's disease pathology and reversed the memory impairment of mice bred to develop symptoms of the neurodegenerative disease, a new study by the University of South Florida reports. Researchers found that the protein, GM-CSF, likely stimulates the body's natural scavenger cells to attack and remove Alzheimer's amyloid deposits in the brain.

NCF announces formal disease model for Chronic Fatigue Syndrome

The National CFIDS Foundation Inc., of Needham Mass, has announced its formal disease model for Chronic Fatigue Syndrome (CFS) also known as Chronic Fatigue Immune Dysfunction Syndrome (CFIDS) as well as Myalgic Encephalomyelitis (ME). According to the NCF, a subgroup of patients with CFS fit a unique disease profile based on a model for a radioactive toxin.

Study supports role for SNARK protein in regulating glucose transport during muscle contraction and exercise

Skeletal muscles combust both lipids and carbohydrates during exercise. The carbohydrates consist of both glycogen stored in the muscles as well as glucose extracted from the blood. Being a major sink for glucose disposal, skeletal muscle represents an important model tissue for studying the intracellular signaling pathways leading to increased glucose transport.

Oxytocin level associated with parent-specific styles of interaction: Research

The hormone oxytocin has come under intensive study in light of emerging evidence that its release contributes to the social bonding that occurs between lovers, friends, and colleagues. Oxytocin also plays an important role in birth and maternal behavior, but until now, research had never addressed the involvement of oxytocin in the transition to fatherhood.

Researchers develop tiny color-changing sensor molecules

A new approach to building an "artificial nose" using fluorescent compounds and DNA could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists. If their method lives up to its promise, it could one day detect everything from incipiently souring milk to high explosives.

Study finds genetic change in chromosome 4 causes FSHD

The Muscular Dystrophy Association today heralds a landmark muscular dystrophy advance by an international study team of scientists and physicians from the Netherlands, United States, France and Spain. Led by MDA-grantee Silvère van der Maarel, Ph.D., at Leiden University Medical Center in the Netherlands, the collaborative study of more than 2,300 people found that two distinct genetic changes on chromosome 4 must be present to cause facioscapulohumeral muscular dystrophy (FSHD).

New squeeze test for screening potential drugs for Alzheimer's

Brain cells exposed to a form of the amyloid beta protein, the molecule linked to Alzheimer's disease, become stiffer and bend less under pressure, researchers at UC Davis have found. The results reveal one mechanism by which the amyloid protein damages the brain, a finding that could lead to new ways to screen drugs for Alzheimer's and similar diseases.
