Stem cell study seeks to prevent heart failure
University of Rochester Medical Center researchers today announced the launch of a study that will examine whether transplanted stem cells can be safely used to treat damaged heart muscle in patients just after their first heart attack. view more (2006-01-25)
A fundamentally new approach to improving cancer chemotherapy
A new strategy for getting anti-cancer drugs to kill cancer cells, without causing serious harm to normal cells in the body, is reported in the current [June] issue of ACS Chemical Biology, a monthly peer-reviewed journal of the American Chemical Society. view more (2006-06-06)
Hurricane Katrina: Who Was Hit? Who Will Return?
The Gulf Coast's African Americans and poorest residents were disproportionately impacted by Hurricane Katrina, according to new findings from Brown University sociologist John Logan. view more (2006-01-26)
OHSU study says stem cell 'fusion' occurs in tumors
An Oregon Health & Science University study is adding credence to an increasingly popular theory that fusion is what bonds stem cells with bone marrow cells to regenerate organ tissue. view more (2006-05-10)
Novel regulatory mechanism identified for key tumor suppressor p53
Collaborating scientists from The Wistar Institute in Philadelphia and The Vienna Biocenter in Austria have identified a novel mechanism involved in normal repression of the p53 protein, perhaps the single most important molecule for the control of cancer in humans. view more (2006-11-16)
Simple chemical procedure augments therapeutic potential of stem cells
Adult stem cells resemble couch potatoes if they hang out and divide in a dish for too long. They get fat and lose key surface proteins, which interferes with their movement and reduces their therapeutic potential. Now, via a simple chemical procedure, researchers have found a way to get these cells off the couch and over to their therapeutic... view more... (2008-10-31)
Researchers discover human embryonic stem cells are the ultimate perpetual fuel cell
A startling discovery on the development of human embryonic stem cells by scientists at McMaster University will change how future research in the area is done. view more (2007-07-12)
Umbilical cord blood stem cell transplant may help lung, heart disorders
Two separate studies published in the current issue of Cell Transplantation (18:8), - now freely available on-line have shown that transplanted human-derived umbilical cord blood (UCB) stem cells transplanted in an animal model had positive therapeutic effects on specific lung and heart disorders the animal models. view more (2009-11-24)
Students work hand in glove for business success
A large number of disposable gloves used in surgery are punctured or damaged during operations, bringing a high risk of infecting medical staff and patients. Now five enterprising University of York students have devised an imaginary new glove which could warn when it has been damaged and may pass on diseases such as HIV or hepatitis. Currently... view more... (2002-01-15)
Dually porous glass shows promise in helping damaged bone regenerate
Victims of osteoporosis and broken bones may get a boost from a new type of biocompatible glass that shows promise in helping damaged and diseased bone to regenerate, says an international team of researchers. view more (2006-12-06)
To protect against liver disease, body puts cells 'under arrest'
A stable form of cell-cycle arrest known to offer potent protection against cancer also limits liver fibrosis, a condition characterized by an excess of fibrous tissue, according to a new report in the August 22nd Cell, a Cell Press publication. view more (2008-08-22)
Leishmaniasis parasites evade death by exploiting the immune response to sand fly bites
Cutaneous leishmaniasis, a disease characterized by painful skin ulcers, occurs when the parasite Leishmania major, or a related species, is transmitted to a mammalian host by the bite of an infected sand fly. view more (2008-08-15)
July 23, 2009 Circulating osteogenic precursor (COP) cells form bone in vivo. Bone from Blood: Circulating Cells Form Bone Outside the Normal Skeleton, Penn Study Finds
The accepted dogma has been that bone-forming cells, derived from the body's connective tissue, are the only cells able to form the skeleton. view more (2009-07-24)
Stem cell breakthrough: Monitoring the on switch that turns stem cells into muscle
In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers-including 2007 Nobel Prize winner Mario R. Capecchi-have created a "switch" that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. view more (2009-03-31)
Drug studied as possible treatment for spinal injuries
Researchers have shown how an experimental drug might restore the function of nerves damaged in spinal cord injuries by preventing short circuits caused when tiny "potassium channels" in the fibers are exposed. view more (2009-11-20)
Heart smart: new drug improves blood flow
A new drug has been shown to improve blood flow in diseased arteries, reducing the risk of high blood pressure and heart attacks. view more (2006-09-05)
New research demonstrates bone-marrow derived stem cells can reverse genetic kidney disease
The discovery that bone-marrow derived stem cells can regenerate damaged renal cells in an animal model of Alport syndrome provides a potential new strategy for managing this inherited kidney disease and offers the first example of how stem cells may be useful in repairing basement membrane matrix defects and restoring organ function. view more (2006-04-25)
SLU scientists have identified the first gene regulating programmed cell death in plant embryos
A research team at the Swedish University of Agricultural Sciences, SLU, has succeeded in isolating a novel gene that regulates cell death in plant embryos. This is a world first. The team consists of scientists from the Department of Plant Biology and Forest Genetics, headed by Peter Bozhkov and Sara von Arnold. The team has discovered... view more... (2004-06-01)
The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. view more (2007-08-28)
Targeted drug delivery now possible with 'pHLIP' peptide
Scientists at Yale and the University of Rhode Island report the development of a peptide that can specifically and directly deliver molecules to the inside of cells like a nanosyringe, creating a new tool for drug delivery, gene control and imaging of diseased tissues. view more (2006-04-12)
