Study finds chance of appendicitis 'very low' if appendix is not visible on CT
The probability of acute appendicitis is very low if there is no distinctly apparent appendix on the CT scan, and in the absence of any secondary CT signs of appendicitis, says a study by researchers from the Northwestern University Feinberg School of Medicine and Northwestern Memorial Hospital in Chicago.

Study shows CRC risk higher in people with insulin-requiring type 2 diabetes

Data show ZYVOX is more effective and reduces costs
Treatment with ZYVOX® (linezolid injection, tablets and for oral suspension) for complicated skin and soft tissue infections caused by suspected or proven methicillin-resistant Staphylococcus aureus resulted in higher cure rates and decreased healthcare costs compared with intravenous vancomycin, according to a U.S. sub-analysis of data presented today at the annual meeting of the Infectious Diseases Society of America.

Diatom genome reveals key role in biosphere's carbon cycle
The first genetic instruction manual of a diatom, from a family of microscopic ocean algae that are among the Earth's most prolific carbon dioxide assimilators, has yielded important insights on how the creature uses nitrogen, fats, and silica to thrive.

Helping investigators gather crime evidence from PDAs
Researchers at the National Institute of Standards and Technology recently examined a number of software tools designed to acquire information from operating systems used in personal digital assistants (PDAs) in order to provide advice to forensic investigators who increasingly need to extract criminal evidence from these devices.

DNA sequence controls expression of gene involved in cancer
Scientists have discovered a DNA sequence that causes the destabilization, and hence decay, of the protooncogene bcl-2 (B-cell lymphoma/leukemia-2).

MR is better than mammography for detecting additional disease in women with breast cancer

RFA effective for easing lung cancer symptoms; CT findings identified that verify successful RFA
CT-guided radiofrequency ablation (RFA) is effective in easing the symptoms of lung tumors that cannot be removed by surgery, and enhancement pattern and changes in the size of the tumor as shown on CT are the most important factors for determining whether that ablation has been successful, according to a pair of independent studies in the October 2004 issue of the American Journal of Roentgenology.
