New method allows for stem cell propagation and neurogenesis in cell culture

Researchers are now able to study stem cells from the brains of adult mice and their neurogenesis in long-term cell cultures.

New discoveries about stem cells in leukemia, breast and colon cancer

Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research. With each new study, scientists are learning more about cancer-initiating properties of stem cells at organ sites and throughout the body.

Cell structures exhibit novel behaviors, mimic red blood cells and liquid crystals

Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.

Inhaled corticosteroids deserve further consideration for lung cancer chemoprevention

Among a group of mostly older male veterans suffering from chronic obstructive pulmonary disease (COPD), an illness that offers a greater susceptibility to lung cancer, researchers found that regular use of high dose inhaled corticosteroids (ICS) lowered the risk of developing lung cancer.

Discovery of pancreatic cancer stem cells could lead to more effective therapies

Scientists in the United States have identified for the first time the stem cells linked to pancreatic cancer.

Single protein plays a major role in prion diseases

A single protein plays a major role in deadly prion diseases by smashing up clusters of these infectious proteins, creating the "seeds" that allow fatal brain illnesses to quickly spread, new Brown University research shows.

New discovery boosts basic understanding of prion infections

Brittleness is often seen as a sign of fragility. But in the case of infectious proteins called prions, brittleness makes for a tougher, more menacing pathogen.

Engineered heart tissue offers insights into irregular heartbeats

Engineers who have induced heart cells in culture to mimic the properties of the heart have used the tissue to gain new insight into the mechanisms that spawn irregular heart rhythms.

Genetic fingerprint unmasks microbial vandals

For the first time DNA analysis can identify paper-degrading microorganisms.

Israeli scientists successfully transplant ovaries in sheep and trigger early embryonic development

Israeli scientists report in Human Reproduction that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and triggered them in the laboratory into early embryonic development.

Ichor Medical Systems issued key patent

Ichor Medical Systems today announced that it has been issued a patent that protects vital elements of the company's technology.

Researchers make headway in mystery of migraines

The research, published in the new issue of the Proceedings of National Academy of Sciences (PNAS), reveals how gene mutations known to cause a form of inherited migraine target a cellular process involved in brain cell communication.

Unravelling the Ebola virus’s biological cycle

Ebola virus infection in humans provokes a violent haemorrhagic fever. It usually flares up as intense epidemics. These kill 80 % of the people infected. Seven such outbreaks have hit Gabon and the Republic of Congo since 1994, leading to 445 cases resulting in 361 deaths.

Mathematical model describes the electrical storm that rages during a brain seizure

"We're trying to get to the underlying state of the brain that leads to these seizures," said Mark Kramer, a Ph.D. student in UC Berkeley's Applied Science and Technology Program and lead author of the paper. "Our hope is that the model can highlight potential areas where a seizure can be stopped."

Novel vaccine that uses immune cells as factories to produce Her2/neu protein may offer a way to treat some breast cancers

Based on successful animal studies, a novel vaccine that uses immune cells as factories to produce Her2/neu protein may offer a way to treat some human breast cancers, say researchers at The University of Texas M. D. Anderson Cancer Center.

Genomics tools provide clues to what causes 400 million cases of gastrointestinal disease each year

In a study that could benefit medical and food-safety research, scientists have used comparative genomics tools to find clues about why some strains of the bacterium Campylobacter – which each year cause more than 400 million cases of gastrointestinal disease – are more virulent than others.

Discovery shows how embryonic stem cells perform 'quality control' inspections

Biologists at the University of California, San Diego have found a fundamental mechanism used by embryonic stem cells to assure that genetically damaged stem cells do not divide and pass along the damage to daughter stem cells.

Amyloid growth can occur independently of oligomers

Improperly folded proteins are normally destroyed. But in a wide range of diseases, including prion (from proteinaceous and infectious) diseases and neurodegenerative diseases like Parkinson disease and Alzheimer disease, amyloid fibrils, or plaques--misshapen proteins that aggregate into characteristic ropelike configurations--accumulate in tissue.

Hair growing stem cells may one day provide treatments for human hair conditions

Researchers at the Howard Hughes Medical Institute at The Rockefeller University have isolated stem cells from the skin of a mouse, and showed, for the first time, that an individual stem cell can renew itself in the laboratory and then be used in grafts to produce skin, hair and oil glands.

Latest findings on HIV pathogenesis at AIDS Conference in Bangkok

At the XVth International AIDS Conference in Bangkok, Thailand, Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases and chief of the NIAID Laboratory of Immunoregulation (LIR), will present his laboratory’s latest findings on how aberrant immune activation underlies HIV pathogenesis.
