Scientists successfully isolate stem cells from human skin

Scientists at Wake Forest University School of Medicine have successfully isolated stem cells from human skin, expanded them in the laboratory and coaxed them into becoming fat, muscle and bone cells.

Brief course of chemotherapy after surgery should be the new standard of care around the world

A Canadian national clinical trial has found that chemotherapy following surgery for early-stage non-small cell lung cancer significantly improves survival for the disease over just surgery alone.

Breast cancer growth regulator sEGFR holds promise for more targeted treatment

Researchers at Yale School of Medicine have discovered the breast cancer growth regulator sEGFR, which may be a useful tool in monitoring a patient's responsiveness to treatment with the drug letrozole.

Enzyme known as cathepsin G may be a target for anti-inflammatory treatments

The finding by researchers at Washington University School of Medicine in St. Louis shows that an enzyme known as cathepsin G regulates the ability of immune cells known as neutrophils to secrete chemicals that attract other immune cells and start the local inflammatory process. Over time, the excessive accumulation of immune cells can lead to tissue and cartilage damage in joints, causing pain and limiting mobility.

Tricirbine may help fight cancers

H. Lee Moffitt Cancer Center & Research Institute, working in partnership with the University of South Florida (USF), has discovered a new use for an old, previously discredited anti-cancer drug that could add another weapon in the arsenal against several cancers, including tumors of the breast, ovary, colon, skin and prostate.

Light used to regulate protein synthesis

Proteins are the puzzle-pieces of life, involved in how organisms grow and flourish, but studying their complex biological processes in living systems has been extremely difficult.

Technique called phylogenetic footprinting reveals new gene regulation system

By comparing 140 sequenced bacterial genomes, researchers have uncovered a system for regulating genes essential to bacterial replication - and they did it solely by computer keystrokes and mouse clicks.

How can the U.S. health-care system prepare for the huge wave of dementia patients expected by 2010?

How can the U.S. health-care system and more specifically, primary care doctors - the physicians from whom older adults receive most of their care - prepare for the huge wave of dementia patients expected to engulf us in 2010, the year the baby boomers begin to reach 65?

Metabasis and Merck collaborate to develop new treatment for diabetes, hyperlipidemia and obesity

Metabasis Therapeutics and Merck announced today that they have formed a collaboration to research, develop and commercialize novel small molecule therapeutics with potential to treat several diseases, including type II diabetes, hyperlipidemia and obesity, by activation of an enzyme in the liver called AMP-activated Protein Kinase (AMPK).

Adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply

In a ground-breaking study, scientists at Children's Hospital of Pittsburgh have discovered that adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply, a previously unknown characteristic indicating that post-natal stem cells may play an important therapeutic role.

People with diabetes are at higher risk of contracting respiratory, urinary tract and skin infections

People with type 1 or type 2 diabetes are at higher risk of contracting respiratory, urinary tract and skin infections than people without diabetes, according to an article in the August 1 issue of Clinical Infectious Diseases, now available online.

Study shows that low-intensity exercise such as Tai Chi has great potential for health promotion in older people

Older people who took part in a structured programme of Tai Chi found that their balance and physical strength improved, reducing the risk of falls, according to a paper in the latest Journal of Advanced Nursing.

OHSU scientists say low FOXP3 means fewer disease-fighting cells, but new drug may help multiple sclerosis

Oregon Health & Science University researchers have measured genetic changes reflecting a drop in the body's ability to suppress inflammatory cells that attack nerve fibers and promote progression of multiple sclerosis.

Found! - mutant viruses that laid NSW low with gastro

New mutant viruses responsible for gastroenteritis outbreaks in New South Wales in recent times have been identified by research published in Emerging Infectious Diseases, a journal of the US Centers for Disease Control.

A blood test for thyroid cancer can detect persistent or recurrent disease even before doctors can find any trace of a tumor

The study, by researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSU CCC – James), examined how well a test for thyroid cancer can predict whether the disease will recur.

Increasing stiffness of the aging eye may make older adults more susceptible to eye damage following trauma

Using a computer model of the eye, Stitzel and colleagues investigated possible injury mechanisms in the eyes of elderly individuals and the effects of lens stiffness on injury prediction by the model. The new data document that the risk of certain types of eye injury increases with age.

First comprehensive study of the relationship between racial subgroups and colorectal cancer outcome

A new study finds wide variations in colorectal cancer stage of diagnosis and mortality, with some ethnic groups having 10 to 60 percent higher risks of stage III or IV colorectal cancer compared to non-Hispanic whites, and 20 to 30 percent higher risk of death from the disease.

Researchers discover new molecular mechanism that may allow for stem cell-based therapies to treat eye disorders such as retinal degeneration

The finding also reveals how the retina's own stem cells can be directed to aid the growth of new cells to replace diseased or dying ones in the eye. Study results appear in the June 24 issue of the journal Science.

New research raises the possibility that the risk of developing arsenic-related disease is not the same for everybody

Children with a particular variation in the CYT19 gene metabolize arsenic differently than adults with the same genetic variant, according to a new research report. The findings have important implications for the safety of drinking water worldwide and the use of arsenic as a cancer drug.
