Mothers and offspring can share cells throughout life - with positive and negative effects

Cutting the umbilical cord doesn't necessarily sever the physical link between mother and child. Many cells pass back and forth between the mother and fetus during pregnancy and can be detected in the tissues and organs of both even decades later. This mixing of cells from two genetically distinct individuals is called microchimerism. The phenomenon is the focus of an increasing number of scientists who wonder what role these cells play in the body.

Discovery of quick method for making human monoclonal antibodies against flu

Human monoclonal antibodies (mAbs) - highly specific, identical, infection-fighting proteins produced in large quantities in the lab in cell lines that are derived from a single antibody-producing cell - against influenza can be rapidly produced in the lab, according to a new report from scientists supported by the National Institutes of Health (NIH).

Study describes mechanism linking acohol with risk of breast cancer

The known association of alcohol consumption with an increased risk of breast cancer has been linked by researchers at the University at Buffalo to a process that causes genes that promote normal cell growth to produce proteins that precipitate unregulated cell growth, an action known as hypermethylation

New concept sends medical images via cellular phones

A process to transmit medical images via cellular phones that has been developed by a Hebrew University of Jerusalem researcher has the potential to provide sophisticated radiological diagnoses and treatment to the majority of the world's population lacking access to such technology.

Study explains why steroid therapy for sinusitis and asthma loses its punch over time

Scientists at Johns Hopkins have outlined a new path for potential therapies to combat inflammation associated with sinusitis and asthma based on a new understanding of the body's earliest immune response in the nose and sinus cavities.

Getting to the roots of breast cancer

The lesson learned in eradicating dandelions from your yard could apply in treating breast cancer as well, said researchers from Baylor College of Medicine in Houston in a report that appears online today in the Journal of the National Cancer Institute.

Yale scientists explain metastasis

Metastasis, the spread of cancer throughout the body, can be explained by the fusion of a cancer cell with a white blood cell in the original tumor, according to Yale School of Medicine researchers, who say that this single event can set the stage for cancer's migration to other parts of the body.

Scientists determine drug target for the most potent botulinum neurotoxin

Botulinum neurotoxin - responsible for the deadly food poisoning disease botulism and for the beneficial effects of smoothing out facial wrinkles - can also be used as a dreaded biological weapon. When ingested or inhaled, less than a billionth of an ounce can cause muscle paralysis and eventual death. Although experimental vaccines administered prior to exposure can inhibit the destructive action of this neurotoxin - the most deadly protein known to humans - no effective pharmacological treatment exists.

Human protein may offer novel target for blocking HIV infection

A research group supported by the National Institutes of Health (NIH) has uncovered a new route for attacking the human immunodeficiency virus (HIV) that may offer a way to circumvent problems with drug resistance. In findings published today in the online edition of the Proceedings of the National Academy of Sciences, the researchers report that they have blocked HIV infection in the test tube by inactivating a human protein expressed in key immune cells.

Tests monitoring viral loads, CD4+ count do not significantly affect survival rates among HIV-positive people

Survival rates among HIV-positive people who undergo routine viral load and CD4+ T cell counts were nearly the same as those who do not receive the tests, according to a study published on Friday in the journal Lancet, the CP/Google.com reports (CP/Google.com, 4/24).

Aggregates of red and white blood cells may contribute to sickle cell disease

It's long been known that patients with sickle cell disease have malformed, "sickle-shaped" red blood cells - which are normally disc-shaped - that can cause sudden painful episodes when they block small blood vessels.

Researchers identify new genes that help predict breast cancer outcomes

Not a day goes by without a new story about the environment. Although we often consider the environment on a global scale, cells in our body also have to contend with environmental factors.

Cell-based therapy shows promise in patients with Parkinson's disease

Rush University Medical Center neurosurgeon Dr. Roy A. E. Bakay and colleagues from Emory University, Atlanta found the therapy Spheramine was well-tolerated and patients experienced improvement in Parkinsonian symptoms (tremor, rigidity, slowness of movements, and impaired balance and coordination.)

Scientists find distinct kind of stem cells in the pituitary gland

A team of researchers led by scientists at Cold Spring Harbor Laboratory have for the first time identified stem cells that allow the pituitary glands of mice to grow even after birth.

New drug discovery tool for Alzheimer's disease

An article published in the April issue of the Journal of Alzheimer's Disease presents a detailed characterization of a new drug discovery tool for Alzheimer's disease.

Tissue-specific blood stem cell line established from embryonic stem cells

A research team at the Umea Center for Molecular Medicine (UCMM) in Sweden, led by Professor Leif Carlsson, has managed to specifically establish and isolate the tissue-specific stem cell that produces blood cells (blood stem cell) by using genetically modified embryonic stem cells.

Study looks at anesthetic desflurane and Alzheimer's

In studies of human brain cells, the widely-used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein.

3D view of neurons provided by new technique

A new technique that marries a fast-moving laser beam with a special microscope that look at tissues in different optical planes will enable scientists to get a three-dimensional view of neurons or nerve cells as they interact, said Baylor College of Medicine scientists in a report that appears in the journal Nature Neuroscience.

Discovery of important markers of high risk of type 2 diabetes

Doctors are aware of a range of risk factors, mostly related to the patients' family history, overweight, and lifestyle, that contribute to the risk of developing type 2 diabetes.
