Can pathological techniques help identify primary colorectal signet ring cell carcinoma?
Primary colorectal signet ring cell carcinoma is a rare but distinctive malignancy of the large bowel. More than 96% of signet ring cell carcinomas arise in the stomach, with the rest arising from other primary organs.   view more (2008-05-21)

Study Examines Role of Helicobacter Pylori in Esophageal Cancer Development
Infection with bacteria that can cause peptic ulcers and distal stomach cancer may be associated with a reduced risk of a type of esophageal cancer called adenocarcinoma, according to a study in the March 3 issue of the Journal of the National Cancer Institute. However, that same study found that... view more (2004-03-03)

A potential route for human tumor gene therapy
The type 1 Na+/H+ exchanger (NHE1) is a transmembrane protein found in all eukaryotic cells. One of its functions is to evacuate excessive H+ in the cytoplasm by means of Na+-H+ exchange, resulting in stable intracellular pH value.   view more (2008-05-21)

Which is accurate, CT or MRI?

Incidence of nonmelanoma skin cancer on the rise among young adults
A new study from Minnesota finds the incidence of nonmelanoma skin cancer increasing among men and women under the age of 40, according to an article in the August 10 issue of JAMA.   view more (2005-08-10)

Angiotensin inhibitors and receptor blockers linked to lower risk of nonmelanoma skin cancer
The use of angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) was associated with a reduced risk of basal cell or squamous cell skin cancers in U.S. veterans, researchers report in the August 26 online issue of the Journal of the National Cancer Institute.   view more (2008-08-27)

Ultraviolet B light exposure associated with increased risk of skin cancer
A decreased ability to repair chromosomal damage caused by exposure to ultraviolet B (UV-B) radiation in test tubes may be associated with an increased risk of the common skin cancers basal cell carcinoma and squamous cell carcinoma, but not of melanoma.   view more (2005-12-21)

How is H pylori adhesion to gastric cells associated with MUC1 mucin VNTR size?
The Gram negative bacterium H pylori is involved in the pathogenesis of several gastrointestinal diseases, ultimately leading to gastric carcinoma. Adhesion of the bacteria to the gastric mucosa is an essential step for colonization and infection.   view more (2008-03-19)

Is the spleen able to prohibit tumor cell proliferation?
Primary and metastatic tumors of the spleen are described as unusual, excluding involvement by lymphoma. Indeed, isolated splenic metastasis from colorectal carcinoma is not a common occurrence. Its rareness has been hypothetically explained by several characteristics of the spleen, such as... view more (2007-10-17)

Researchers discover scent of skin cancer
According to new research from the Monell Center, odors from skin can be used to identify basal cell carcinoma, the most common form of skin cancer. The findings, presented at the 236th meeting of the American Chemical Society, may open doors to development of new methods to detect basal cell... view more (2008-08-21)

Study identifies new tumor suppressor
A protein called HLJ1 may work as a novel tumor suppressor in non-small-cell lung carcinoma.   view more (2006-06-21)

Doctors conclude temsirolimus is effective new treatment for advanced renal cell carcinoma
The results of a phase III, randomized clinical study involving patients with advanced renal cell carcinoma and poor prognostic features show temsirolimus improved overall survival when compared to the current treatment for this stage of disease.   view more (2007-05-31)

Making Purer Rings For Pure Lovers
By using powdered metals, produced by passing molten gold, silver or platinum through a high powered jet, manufacturers will be able reduce the amount of impurities found in the ring. These impurities are picked up in conventionally produced rings as they are punched from a sheet of metal and... view more (1999-02-10)

A blue ring around the planet Uranus
The outermost ring of the planet Uranus turns out to have a bright blue color, according to a report in the April 7 issue of the journal Science.   view more (2006-04-07)

By amplifying cell death signals, scientists make precancerous cells self-destruct
When a cell begins to multiply in a dangerously abnormal way, a series of death signals trigger it to self-destruct before it turns cancerous. Now, in research to appear in the August 15 issue of Genes & Development, Rockefeller University scientists have figured out a way in mice to amplify... view more (2008-08-18)

What change does prokineticin 2/Bv8 have in human hepatocellular carcinoma?
Liver hepatocarcinoma is a highly vascularized cancer, and more and more research is focused on the molecules controlling angiogenesis.   view more (2008-03-18)

Unusual carbohydrate structure in the cell walls of tuberculosis bacteria-a new point of attack for drugs?
Even though we have lost much of our fear of tuberculosis in the industrialized countries, according to the WHO about 2 mio. people worldwide die each year of this infectious disease. Researchers at the University of Leeds have now discovered a carbohydrate with an unusual structure in the cell... view more (2004-07-27)

Call For Proposals - Subject Areas for Ring-Fenced Doctoral Awards in the Arts and Humanities
The Arts and Humanities Research Board (AHRB) invites members of the community to make a case for their subject area as one that would benefit from ring-fenced, doctoral awards. Proposals may be submitted by leading academics, Subject Associations or Professional Associations. We would expect HEIs,... view more (2003-07-20)

Cassini finds Prometheus a sculptor of Saturn's rings
New findings from members of the Cassini imaging team show that certain prominent features in Saturn's narrow and contorted F ring can be understood in terms of a simple gravitational interaction with the small moon Prometheus.   view more (2005-10-27)

New Cassini image shows "A" ring contains more debris than once thought
Views of Saturn's stunning ring system from above by the Cassini-Huygens spacecraft now orbiting the planet indicate the prominent A ring contains more debris than once thought, according to a new University of Colorado at Boulder study.   view more (2006-04-07)

How does Fu-Zheng-Jie-Du-Decoction act on PTEN expression in hepatocellular carcinoma?
Many hepatocellular carcinoma (HCC) patients in China may be treated with Traditional Chinese medicine (TCM). Some say it works, others doubt its effectiveness. These stated that a research group in China had found TCM can down-regulate the expression of PTEN in HCC, which may suppress tumor cell... view more (2008-01-17)

Saturn's rings show evidence of a modern-day collision
Scientists on NASA's Cassini mission have spied a new, continuously changing feature that provides circumstantial evidence that a comet or asteroid recently collided with Saturn's innermost ring, the faint D ring.   view more (2006-10-12)

Saturn's faint rings share some of their secrets

A tiny pinch from a 'z-ring' helps bacteria cells divide
In process that is shrouded in mystery, rod-shaped bacteria reproduce by splitting themselves in two. By applying advanced mathematics to laboratory data, a team led by Johns Hopkins researchers has solved a small but important part of this reproductive puzzle.   view more (2007-10-12)

Melanoma risk only partially associated vith exposure to UVB from sunlight
Researchers at The University of Texas M. D. Anderson Cancer Center have found that the risk of developing melanoma, the most deadly form of skin cancer, is only partially associated with exposure to ultraviolet B (UVB) radiation, the rays in sunlight that increase in summer and cause sunburn.   view more (2005-12-21)
