First 3D images of a living cell

A new imaging technique developed at MIT has allowed scientists to create the first 3D images of a living cell, using a method similar to the X-ray CT scans doctors use to see inside the body.

New clues to why persistent acid reflux can turn into cancer

New research from scientists at UT Southwestern Medical Center and the Dallas Veterans Affairs Medical Center underscores the importance of preventing recurring acid reflux while also uncovering tantalizing clues on how typical acid reflux can turn potentially cancerous.

Impaired energy production in heart muscle may underlie heart failure in some hypertensive patients

Many people with long-standing high blood pressure develop heart failure. But some don't. Daniel P. Kelly, M.D., and colleagues at Washington University School of Medicine in St. Louis and other institutions are trying to figure out what could explain that difference.

New ways to prevent bowel cancer

Researchers at the University of Edinburgh Cancer Research Centre have been given a cash boost from Cancer Research UK to help them investigate new ways to prevent bowel cancer.

New study looks at over-the-counter (OTC) anti-aging products

Findings from a study released today revealed that a limited amount of clinical research exists to prove the effectiveness of many over-the-counter (OTC) anti-aging products. The study is published in the July/August 2007 issue of the Aesthetic Surgery Journal, the official peer-reviewed journal of the American Society for Aesthetic Plastic Surgery (ASAPS).

New drug targets for multiple myeloma

Research investigators have identified molecular changes in multiple myeloma cells that activate an important biological pathway associated with cell growth and survival, thereby revealing potential new targets for drugs to treat this cancer.

New cancer stem cells could aid breast cancer research

In some ways, certain tumors resemble bee colonies, says pathologist Tan Ince. Each cancer cell in the tumor plays a specific role, and just a fraction of the cells serve as "queens," possessing the unique ability to maintain themselves in an unspecialized state and seed new tumors. These cells can also divide and produce the "worker" cells that form the bulk of the tumor.

Green tea may help treat psoriasis

Green tea which is already recommended for its cancer-fighting properties, also appears to be a promising new treatment for skin disorders such as psoriasis, lupus-induced lesions and dandruff.

Biomira and Merck KGaA sign agreements on Stimuvax

Biomira Inc. has announced the signing of amended and restated collaboration and supply agreements related to Stimuvax with Merck KGaA of Darmstadt, Germany.

Light-activated molecules used to induce apoptosis in cancer cells

A key challenge facing doctors as they treat patients suffering from cancer or other diseases resulting from genetic mutations is that the drugs at their disposal often don't discriminate between healthy cells and dangerous ones -- think of the brute-force approach of chemotherapy, for instance.

Antioxidant overload

Despite the popular notion that antioxidants, such as vitamins C and E, offer health-promoting benefits by protecting against damaging free radicals, a new study in the August 10 issue of the journal Cell reveals that, in fact, balance is the key.

Researchers discover how Bcl-3 protein stops inflammation

Researchers at the University of Pennsylvania School of Medicine recently identified how a regulatory protein called Bcl-3 helps to control the body's inflammation response to infection by interfering a critical biochemical process called ubiquitination.

Connection between reduced glutathione and heart failure

Antioxidants are widely considered an important defense against heart disease, but University of Utah researchers have found excessive levels of one antioxidant - reduced glutathione - actually may contribute to the disease.

The role of estrogens and polyphenols in hypertension and diabetes

Menopausal women are at relatively high risk for memory loss, high blood pressure (hypertension) and diabetes.

Chromatin remodeling complex connected to DNA damage control

When molecular disaster strikes, causing structural damage to DNA, players in two important pathways talk to each other to help contain the wreckage, scientists at The University of Texas M. D. Anderson Cancer Center report in the August edition of Cell.

New insights into cell division process

Which genes are passed on from mother to child is decided very early on during the maturation of the egg cell in the ovary.

TRF2 and POT1 proteins found on telomeres control DNA damage response pathways

No sooner had cells evolved linear chromosomes than they had a life-threatening problem to solve.

FGFR4 gene plays a complex role in obesity, fatty liver and diabetes

Researchers at the Texas A&M Health Science Center Institute of Biosciences and Technology at Houston have found that a gene in the liver and elsewhere in the body, when inhibited or increased, affects fatty liver and diabetes but does not alleviate both diseases at once.
