Keeping herpes infection in check: Pitt researchers describe immune system strategies
Herpes simplex virus type I can cause bouts of cold sores, blindness and potentially lethal encephalitis when it reawakens from a quiescent state in the nerve cells it infects.   view more (2008-10-10)

Hodgkin lymphoma -- new characteristics discovered
Researchers are still discovering new characteristics of Hodgkin lymphoma, a common form of cancer of the lymphatic system. The malignant cells are derived from white blood cells (B cells), but have lost a considerable part of the B cell-specific gene expression pattern.    view more (2008-10-09)

Researchers design artificial cells that could power medical implants
Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants.   view more (2008-10-09)

Burnham Researchers Turn Cancer Friend into Cancer Foe
Burnham Institute for Medical Research today announced that scientists have created a peptide that binds to Bcl-2, a protein that protects cancer cells from programmed cell death, and converts it into a cancer cell killer.   view more (2008-10-08)

Egg whites solve the 3-D problem
The real world is three-dimensional. That's true even in the laboratory, where scientists have to grow cells to study how they develop and what happens when their growth is abnormal.   view more (2008-10-08)

Surface tension drives segregation within cell mixtures
What does a mixture of two different kinds of cells have in common with a mixture of oil and water? The same basic force causes both mixtures to separate into two distinct regions.   view more (2008-10-07)

Discovery of natural compounds that could slow blood vessel growth
Using computer models and live cell experiments, biomedical engineers at the Johns Hopkins University School of Medicine have discovered more than 100 human protein fragments that can slow or stop the growth of cells that make up new blood vessels.   view more (2008-10-06)

Newly identified cells make fat
To understand where fat comes from, you have to start with a skinny mouse. By using such a creature, and observing the growth of fat after injections of different kinds of immature cells, scientists at the Howard Hughes Medical Institute and Rockefeller University have discovered an important fat... view more (2008-10-06)

Metastatic movements in 3-D
Caswell et al.report in the Journal of Cell Biology how the altered behavior of integrins can prompt metastatic movement in tumor cells.    view more (2008-10-06)

DNA of good bacteria drives intestinal response to infection
A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection.   view more (2008-10-03)

UCR researchers propose minocycline as a promising drug for patients with Fragile X syndrome
A UC Riverside-led team of biomedical scientists has found that a readily available drug called minocycline, used widely to treat acne and skin infections, can be used to treat Fragile X syndrome, the most common inherited cause of mental impairment and the most common cause of autism.   view more (2008-10-03)

Vitamin C supplements may reduce benefit from wide range of anti-cancer drugs
In pre-clinical studies, vitamin C appears to substantially reduce the effectiveness of anticancer drugs, say researchers at Memorial Sloan-Kettering Cancer Center.   view more (2008-10-01)

Reversible 3-D cell culture gel invented
Singapore's Institute of Bioengineering and Nanotechnology (IBN), which celebrates its fifth anniversary this year, has invented a unique user-friendly gel that can liquefy on demand, with the potential to revolutionize three-dimensional (3D) cell culture for medical research.   view more (2008-09-29)

Probiotic bacteria can induce monocyte-derived dendritic cells maturation?
Probiotic bacteria are widely used to relieve the symptoms of many disorders such as inflammatory bowel syndrome, diarrhea, and allergies. Probiotic mixtures have also been found to reduce the symptoms of diarrhea.   view more (2008-09-25)

The small cell neuroendocrine carcinoma of the ampulla of vater
Ampullary small cell neuroendocrine carcinoma is extremely rare and has only been documented in few case reports and retrospective study. The patients with ampullary small cell neuroendocrine carcinoma usually presented after the age of 60 years, and a male predilection was observed.   view more (2008-09-25)

A new therapeutic option for human hepatocyte cancer
p53-impaired tumors may be particularly suitable to parvovirus H-1-induced therapy. Although the p53 deficiency in tumors may induce resistance to chemotherapeutic agents, this will not affect the tumor cell susceptibility to H-1 PV-induced oncolytic infections.   view more (2008-09-24)

Is Bcl-2 protein a major obstacle in treating colorectal carcinoma?
Apoptosis resistance has been shown to contribute to the development of different cancer entities, such as colorectal carcinoma (CRC).   view more (2008-09-24)

Cancer-causing gut bacteria exposed
Normal gut bacteria are thought to be involved in colon cancer but the exact mechanisms have remained unknown. Now, scientists from the USA have discovered that a molecule produced by a common gut bacterium activates signalling pathways that are associated with cancer cells.   view more (2008-09-22)

Pittsburgh researchers identify source of multipotent stem cells with broad regenerative potential
In a promising finding for the field of regenerative medicine, stem cell researchers at Children's Hospital of Pittsburgh of UPMC have identified a source of adult stem cells found on the walls of blood vessels with the unlimited potential to differentiate into human tissues such as bone, cartilage... view more (2008-09-22)

Healthy blood vessels may prevent fat growth
The cells lining blood vessels are known to be important for maintaining health, but researchers at the Indiana University School of Medicine believe these cells may perform an unsuspected task - controlling the development of fat cells.   view more (2008-09-22)

UNC scientists turn human skin cells into insulin-producing cells
Researchers at the University of North Carolina at Chapel Hill School of Medicine have transformed cells from human skin into cells that produce insulin, the hormone used to treat diabetes.   view more (2008-09-18)

Why some primates, but not humans, can live with immunodeficiency viruses and not progress to AIDS
Key differences in immune system signaling and the production of specific immune regulatory molecules may explain why some primates are able to live with an immunodeficiency virus infection without progressing to AIDS-like illness, unlike other primate species, including rhesus macaques and humans,... view more (2008-09-17)

Stem cells may solve mystery of early pregnancy breast cancer protection
The answer to why an early pregnancy seems to protect against breast cancer could rest with a decrease in stem cells found after animals have given birth, said researchers at Baylor College of Medicine in a report that appears in the current issue of the journal Stem Cell.   view more (2008-09-17)

Colorful spy tactics track live cells supporting cancerous tumors
A new advance in cellular imaging is allowing scientists to better understand the movement of cells in the area around tumors, also known as the tumor microenvironment.   view more (2008-09-17)

Embryonic stem cells might help reduce transplantation rejection
Researchers have shown that immune-defense cells influenced by embryonic stem cell-derived cells can help prevent the rejection of hearts transplanted into mice, all without the use of immunosuppressive drugs.   view more (2008-09-16)
