Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...ack. The study involves an intravenous infusion of adult mesenchymal stem cells from healthy donor bone mar...that mesenchymal stem cells (MSC) are found in the adult bone marrow and have the potential to develop into mature heart cells and new blood vessels. The MSC...

Viral protein helps infected T cells stick to uninfected cells

...rldwide. About 5 percent of those infected develop adult T cell leukemia or lymphoma (ATLL), an aggressive disease characterized by a long latent period and the proliferation of T cells. The infected cells are spread from person to person during sexual activity and by blood and breast milk. In the body, ...

NJIT engineer poised to take stem cell research a step forward

...uild a laboratory to test if stem cells taken from adult bone marrow can be made to turn into neurons. If her research shows that the cells can turn into neurons -- the nerve cells in the body that control brain and spinal cord function -- patients with spinal cord injuries could be healed with injections ...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...researchers discovered that certain regions of the adult brain do in fact retain their ability to support and promote cell renewal (neurogenesis) throughout life, especially under conditions of mental stimuli and physical activity. One such brain region is the hippocampus, which subserves certain memory fu...

Alternatives to the use of nitrate as a fertiliser

..., substances that are said to be cancerous, in the adult stomach. This is why it is necessary to find a balance between agricultural productivity and quality crops, while maintaining environmental conditions. These are the conclusions of Mª Dolores Domínguez Valdivia of the Department of Environmental Sc...

Flu not the only germ threat this time of year

...t involving hand washing among staff members at an adult day care center. She found that respiratory infections were less frequent among residents cared for by workers equipped with packs containing germ-killing hand gels who used the gels regularly. The team also found that RSV was spread to residents mai...

Thin tough skin, slow-growing gills protect larval Antarctic fish

... ice crystals. "The way that we've understood how adult polar fishes survive has been based on their use of these antifreeze proteins to lower the freezing point of their internal fluids," said lead author Paul A. Cziko, a research specialist in the department of animal biology. "We finally got a chance t...

Findings advance use of adult stem cells for replacement bone

...ce University have discovered a new way to culture adult stem cells from bone marrow such that the cells th...approaches involve three components: the harvested adult stem cells, growth factors that cause the stem cells to differentiate into the right kind of tissue ...

Scientists discover a genetic switch that links animal growth and cancer

...esearch develop quickly, growing from an egg to an adult in three days, as compared to mice, for example, which take several months. The similarities between the number and identity of genes in humans and worms allow researchers to extrapolate from worms to humans in their genetic research. ...

Insects that produce males from unfertilized eggs reveal a surprising cellular feat

...But the development of an unfertilized egg into an adult (called parthenogenesis) remains a mysterious process. One mystery has been the origin of the centrosome, an essential cellular component that is ordinarily derived from the sperm after fertilization. A new study led by researchers at the Universit...

FSU biologist says new dinosaur is oldest cousin of Tyrannosaurus rex

...venile who died prematurely, not simply a smaller, adult female. "I study these animals as living organisms, not just as specimens on an evolutionary tree," Erickson said. "For me, it's about how they lived, not just how they died." Guanlong lived in China –?its remains were found in the Junggar Basin of...

Potential heart benefit found in stem cells

...he body that need repair or replacement. In fact, adult autologous (as in, using one's own cells) stem cells may be a novel approach for cardiac regeneration after heart attacks. In a closer look at their regenerative function, researchers from Tulane University in Louisiana evaluated the stem cell trans...

How can we protect patients with weakened immune systems from influenza?

...er Center, leads both projects. A third group of adult patients suffers from autoimmune diseases, those in which an abnormal immune system turns on itself: systemic lupus erythematosus and Sjogren's syndrome. Core research facilities will assist all the projects in systematically measuring T cell and B ...

Component in soy products causes reproductive problems in laboratory mice

...responsible for the reproductive problems found in adult mice." Female mice were injected with three different doses of genistein during their first five days of life. The genistein given to the mice was comparable to what human infants might receive in a soy-based formula, which is approximately 6-9 mg/...

Exotic crab poised for widespread UK invasion

...and and can migrate up to 1,000km while growing to adult size. A decrease in river pollution and a prolonged period of drought in the late 1980s - which together improved habitat conditions for mitten crabs - are potential reasons for the recent population rise. Dr Bentley, of Newcastle University's ...

Insects and mammals share common fat-building pathway, study suggests

... that the Hh pathway in mammals determines whether adult stem cells are fated for fat or bone. The findings suggest that drugs that target the Hh pathway might prove useful for the treatment of osteoporosis, diabetes, obesity, and lipodystrophy, a disease characterized by the absence of fat, said the resea...

New study reveals promising osteoporosis treatment

...eros divided a sample of 72 (36 males, 36 females) adult Sprague-Dawley rats (average weight, 160g) into six groups receiving the following diets: control; mineral deficiency-induced osteoporosis (MD); MD supplemented with Mg-CaP; Zn-CaP; F-CaP; and Mg/Zn/F-CaP. Each supplement was 0.6% of the MD diet. The...

Gut protein found to protect against infection and intestinal breakdown

...heavily lined the inside folds of the intestine in adult mice. "It's perfectly positioned," Dr. Kliewer said. "It's expressed in just the right place to protect us from the environment." When the bile ducts of mice were tied off, preventing bile from reaching the intestine, adding GW4064 prevented damage...

Study: Paramedics save more lives when they don't follow the rules

The new approach is not recommended for respiratory arrest, a much less common situation following, for example, drowning or drug overdose." As a cause of death, out-of-hospital cardiac arrest is second only ...
