Roadmap to overcome obstacles for using induced pluripotent stem cells

The possibility of developing stem cells from a patient's own skin and using them to treat conditions as diverse as Parkinson's disease, Alzheimer's disease and cancer has generated tremendous excitement in the stem cell research community in recent years. Such therapies would avoid the controversial need for using stem cells derived from human embryos, and in theory, also bypass immunological problems inherent in using cells from one person to treat another.

Conference to focus on connection between fluid balance and hypertension

Each day we consume liquids in order to keep hydrated and maintain our body's fluid balance. But just as a water balloon can get overtaxed by too much liquid, the human body is negatively affected when it retains fluids because it is unable to eliminate them properly. One of the key variables influencing how much fluid we hold in our bodies is ordinary table salt.

Researchers reveal molecular mechanisms responsible for organizing intestinal epithelium

How do cells know where to position themselves and where to accumulate in order to carry out their functions correctly within each organ? Researchers with the Colorectal Cancer Lab at IRB Barcelona have revealed the molecular mechanisms responsible for organizing the intestinal epithelium into distinct comportments, defined by frontiers or territories.

Therapeutic hypothermia might not be effective for children after heart attack

Intravenous delivery of cold fluids to reduce body temperature quickly after a heart attack and improve neurologic outcomes may not be as effective in children as it is in adults, according to a study reported in Therapeutic Hypothermia and Temperature Management, a peer-reviewed journal published by Mary Ann Liebert, Inc.

Invadopodia could help survival of cancer cells

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.

U.S. Judge approves federal funding for embryonic research

Federal funding of human embryonic stem cell (hESC) research is now legal in the United States. Chief judge of the US District Court for the District of Columbia Royce Lamberth has ruled on the case Sherley et al. v. Sebelius, in favor of hESC research. This overturns an existing law that prohibits the government from funding research that destroys the embryo.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

Strategies toxins use to invade human host cells

Toxins produced by plants and bacteria pose a significant threat to humans, as emphasized by the recent effects of cucumber-borne Shiga toxin in Germany. Now, new research published on July 21st by the Cell Press journal Developmental Cell provides a clearer view of the combination of similar and divergent strategies that different toxins use to invade a human host cell.

Caffeine reduces women's chances of becoming pregnant

Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman's ovaries to her womb. "Our experiments were conducted in mice, but this finding goes a long way towards explaining why drinking caffeinated drinks can reduce a woman's chance of becoming pregnant," says Sean Ward, professor of physiology and cell biology, at the University of Nevada School of Medicine, who conducted the study.
