Smallpox Vaccine May Help Fight Cervical Cancer

...ed to most cases of the illness, and prevent early cell changes from developing into cervical cancer. A mo... In addition to treating women with pre-cancerous cell changes, scientists are also working on vaccines for women with advanced disease and preventive vacc...

A need for new stem cell lines

According to researchers, existing stem cell lines could accrue genetic abnormalities over time and new stem cell lines will likely be needed. Dr. Burt Vogels, chairman of a key stem cell research committee of the...

Research of Ritalin

...ta do suggest that there are effects of Ritalin on cell function that outlast the short term and we should sort that out," Dr Walker said. ADHD researcher Dr Alasdair Vance of Melbourne's Alfred Hospital said the study demonstrated the importance of studying the long-term effects of Ritalin. Dr Vance sa...

Women more susceptible to brain damage from ecstasy

Women are more likely than men to suffer brain cell damage from long-term use of the party drug ecstas... shown that women are more vulnerable to the brain cell damage. The researchers studied 54 people whose use of the drug varied from moderate to heavy. Sixte...

Garlic fights malaria and cancer

...uced (the opposite of oxidation) and stored in the cell like energy in a battery. This reduced glutathione can then be brought out to absorb damage caused by oxygen and other harmful particles when needed.The glutathione system is of particular importance in cells that rapidly reproduce, like cancer cells...

Cut down on fries

...common form of oesophageal cancer, called squamous cell carcinoma, the researchers questioned 234 women with the disease from Oxfordshire, East Anglia, Trent and Eastern Scotland about their lifestyles. Women who ate a cooked breakfast each morning were at more than twice the risk of developing oesophagea...

High Demand for a child vaccine

...ghest risk of infection, such as those with sickle cell anemia, the AIDS virus or other diseases that undermine the immune system. PREVNAR fights the bacterium streptococcus pneumoniae, the leading cause of pneumonia, meningitis and millions of ear infections every year in children. According to the Food...

Stem cell research

...ial of embryonic stem cells - a kind of 'template' cell - by directing their differentiation into a specialised cell such as a nerve or muscle cell. The Britain-based team, headed by Dr Martin Cliffer,University's Ins...

Cure for blindness

...ay of hope for visually- impaired patients.Retinal cell transplants can restore vision in blind rats, thereby opening up new possibilities for them. Researchers at the University of Texas, have transplanted human retinal cells into rats born with a predisposition to blindness.// Experiments showed that th...

Olive oil does good

...mine oxidase (DAO). DAO is thought to regulate the cell turnover in the bowel lining and reduced levels of this enzyme could be responsible for abnormal cell turnover. But the Oxford researchers found the olive oil seemed to reduce the amount of bile acid ...

Low cholestrol,low behaviour

...nt component of the brain, especially of the nerve cell membranes," he said. "It makes sense that if you have got a high or low level of cholestrol that might influence the way the nerve cells work." Dr Garland said impulsivity stimulated by low cholesterol levels could be responsible for many types of da...

New drug may stop alopecia

... by inhibiting the action of an enzyme involved in cell division. By applying GW8510 directly to the scalp, the drug does not enter the bloodstream and affects only the hair cells and not the cancer cells....

Genes for Vision discovered

...s makes photoreceptors the most well characterised cell type in the body,” said Cepko. The database provides a genetic lantern by which to see the goings on inside photoreceptors. Fro ex, by removing a gene, and hence its protein, we can understand how that protein usually functions in cells. Thus the r...

Target for obesity treatment

...d the gene which is involved in the process of fat cell development. Targeting this gene could lead to new therapies against obesity. Creating fat cells is a two-step process: generalized cells first turn into transitional fat cells, then PPARgamma helps turn those transitional cells into fat cells. The...

Control of inflammation

Particular cell surface molecules sense runaway inflammation and tissue damage, say researchers, Michail Sitkovsky, and his coworkers at the National Institute of Allergy and infectious Diseases (NIAID).The finding appeared in Nature.// Inflammation, tissue swelling...

In other words, junk peptides result from genetic mistakes. The immune system cells of mice, in fact, did recognise one of the p...

This is the process that some medical scient...

Organs made from cloned embryos
