African-American men understimate risk of prostate cancer
...cted data on what 243 patients expected from their biopsies
and their anxiety levels while waiting in a urology clinic. The average age of these patients was 63. Almost 40 percent of the men were African-American. Fifty-six percent had at least a college education level. Despite being referred for biopsy b...
OHSU Cancer Institute, VA researchers find way to identify which men need a second biopsy

Muscle stem cells effectively treat urinary incontinence long term
...rial. In the study, Dr. Carr and colleagues took biopsies
of skeletal muscle tissue from eight female patients and isolated and expanded the stem cells from the tissue in culture. In an outpatient setting, the patients then received injections of the muscle-derived stem cells into the area surrounding the u...
Topical retinol helps reduce wrinkles associated with natural skin aging
...reated arm compared with the control arm. The skin biopsies
revealed that the retinol increased the production of glycosaminoglycan and procollagen, structural components of the skin. "Topical retinol improves fine wrinkles associated with natural aging," the authors conclude. "Significant induction of glyc...
Gel derived from a patient's own blood may help promote wound healing

(removal of skin) were performed on each leg. During the six-month follow-up, none of the participants developed infections and no serious adverse events were reported. "Over a 42-day period, the autologous platelet geltreated sites had statistical...
New research supports early testing for prostate cancer
...at UCSF. Patients received repeat prostate needle biopsies
at 12-24 month intervals, trans-rectal ultrasound (TRUS) every 6-12 months and PSA measurements every three months to track progression. Researchers defined progression as a change in PSA of greater than 0.75 ng/ml per year, increase in lesion size (...
New mechanism identified for resistance to targeted lung cancer drugs
...at, when patients' tumors become resistant, repeat biopsies
to identify which resistance mechanism is involved will be critical and could help us develop effective therapies for those resistant tumors," adds co-author Lewis Cantley, PhD, of the Beth Israel Deaconess Medical Center. To that end, the invest...

Energy supplement under study for Parkinson's disease
...cernible in postmortem brain studies and in muscle biopsies
and measures of platelet activity in the living. By giving more energy to the cell, you are giving them a safety margin, Dr. Sethi says. If a cell is dying, it takes another route and that would be surviving. The goal is to slow progression of a ...
Multiple low-energy plasma skin treatments may help diminish facial wrinkles

were also taken from six patients before and 90 days after all three procedures. Three months after treatment, the participants had 37 percent fewer wrinkles as judged by the researchers, and the patients reported a 68 percent improvement in overal...
The science behind a wrinkle-filler: Researchers discover for the first time how product works
... 84 years, and the subsequent analyses of the skin biopsies
(including immunostaining and gene expression). Some of the key findings relate to fibroblasts, which are in the dermis, the layer of the skin below the epidermis (outer layer). In young people, fibroblasts are stretched, and this produces enough ...
Gene expression test reveals ER and HER-2 status of breast tumors
.... The samples included both fine needle aspiration biopsies
and traditional biopsies. The team used 195 fine-needle biopsy samples to set gene expression thresholds that predicted ER-positive status with 90 percent accuracy and HER-2-positive status with 93 percent accuracy. They then applied those threshol...
New screening process helps better diagnose oral cancers

without additional risk of false negatives." Patients with early stage oral cancer are typically examined by their doctor for suspicious areas in the mouth and throat area. Doctors in this study wanted to test the value of two diagnostic aids in eval...
Fosrenol data show evidence of trends towards improved bone formation in CKD stage 5 patients

to assess participants' bone health at baseline and at one and two years of treatment with FOSRENOL (n=32 and 32, respectively) or standard phosphate binder therapy (n=34 and 24, respectively). The study results showed that FOSRENOL effectively redu...

undertaken, 80 come back negative. The psychological costs and the expense (billions of dollars in the U.S. each year) of the original spurious readings have made reducing the false-positive rate a priority among medical researchers. At the Karmano...
Researchers set benchmarks for screening mammography

do add to the cost and anxiety of mammography," said Dr. Rosenberg. "However, we are continually working to improve the test from both ends--finding cancers while minimizing unnecessary work-ups."...
