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.

Combination of 2 FDA approved drugs eliminate HIV infection

Researchers at the University of Minnesota Academic Health Center have identified two drugs that, when combined, may serve as an effective treatment for HIV.

'Rotten eggs' gas inside knee joint protects against inflammation

Hydrogen sulfide (H2S) is a gas more commonly associated with the smell of 'rotten eggs' and blocked drains. However, it has now been shown to be present naturally in our bodies and reside in knee joint synovial fluid, the protective fluid found in the cavities of joints that reduces friction between the cartilage of joints during movement. Synovial fluid H2S may play a role in reducing inflammation in joints.

FSH society applauds findings of facioscapulohumeral muscular dystrophy

This is what we have all been working towards and fighting for, says Daniel Paul Perez, co-founder, president and CEO of the FSH Society and a 48-year-old patient with facioscapulohumeral muscular dystrophy (FSHD), applauding the researchers whose study on yesterday's ScienceXpress, the journal Science's online advanced edition, pinpoints for the first time the exact genetic mechanism triggering FSHD, the most common muscular dystrophy.

Dilation of blood vessels restores muscle synthesis in elderly

University of Texas Medical Branch at Galveston researchers believe they've found a way to use widely available blood pressure drugs to fight the muscular weakness that normally accompanies aging.

Causes and consequences of increased adiposity and decreased muscle and bone mass

Increased adiposity and decreased muscle mass contribute substantially to age-dependent disease and disability. In particular age-related increase in adiposity is quickly becoming a major threat to public health throughout the world. Although the hypothesis that age-related changes in body composition are due to lifestyle choices alone is well accepted, it is a vast oversimplification.
