Kidney Stones :: Kidney stones and nanoparticles
Researchers at Mayo Clinic have successfully isolated nanoparticles from human kidney stones in cell cultures and have isolated proteins, RNA and DNA that appear to be associated with nanoparticles.
Growth
Cancer :: MIT implant could measure tumor growth, treatment
A tiny implant now being developed at MIT could one day help doctors rapidly monitor the growth of tumors and the progress of chemotherapy in cancer patients.
Colorectal Cancer :: Estrogen study provides new impetus for development of colon cancer drugs
The female hormone estrogen may hold important clues for scientists working on new therapies for colon cancer, a study by Dana-Farber Cancer Institute researchers suggests.
Melanoma :: Study identifies characteristics of fast-growing skin cancers
Melanomas (skin cancers) are more likely to grow rapidly if they are thicker, symmetrical, elevated, have regular borders or have symptoms, according to a report in the December issue of Archives of Dermatology, one of the JAMA/Archives journals. In addition, rapidly progressing melanoma is more likely to occur in elderly men and individuals with fewer moles and freckles, and its cells tend to divide more quickly and have fewer pigments than those of slower-growing cancers.
Glioblastoma :: Novel EGFR ectodomain mutations in glioblastoma
The Epidermal Growth Factor Receptor, a so-called kinase protein, is often abnormally active in cancer. A new class of anticancer drugs inhibiting the activated EGFR kinase have shown to be effective against such cancers, especially lung cancer. In a new study in PLoS Medicine, researchers have catalogued and characterized the mutations in the EGFR gene that occur in glioblastoma, a deadly type of brain tumor.
Low Fat Diet :: Low fat diets reduce breast cancer risks
The first experiment ever to show low-fat diets could help prevent a return of breast cancer now reveals, with longer followup, that the benefit was almost exclusively to women whose tumour growth was not driven by hormones.
Cancer :: Run amok enzyme causes same problems in both humans and fruit flies
An enzyme found at elevated levels in several human cancers has been linked to abnormal tumor growth in fruit flies, a discovery that provides a new model for understanding the link between stem cell biology and cancer, according to researchers at the University of Oregon.
Breast Cancer :: Breast cancer drop linked to decline in HRT
In 2003, breast cancer incidence in the United States dropped sharply, and this decline may largely be due to the fact that millions of older women stopped using hormone replacement therapy (HRT) in 2002, according to a new analysis led by researchers at The University of Texas M. D. Anderson Cancer Center.
Breast Cancer :: ARIMIDEX with HERCEPTIN Extended Survival in Breast Cancer
Data was presented today showing that postmenopausal women who received ARIMIDEX (anastrozole) and Herceptin (trastuzumab) in combination had a significant improvement in progression-free survival when treated for advanced breast cancer that was both human epidermal growth factor receptor-2 (HER-2)-positive and hormone receptor-positive.
Rheumatoid Arthritis :: Pfizer’s Celebrex treats Juvenile Rheumatoid Arthritis
The U.S. Food and Drug Administration (FDA) today approved Celebrex (celecoxib) for a new use ? the relief of the signs and symptoms of Juvenile Rheumatoid Arthritis (JRA) in patients two years of age and older. Today’s approval follows the November 29 meeting of FDA’s Arthritis Advisory Committee, in which the committee voted 15 to 1 in favor of approval of this product.
