Fluoroquinolones may reduce the risk of myocardial infarction

By | January 3, 2001

Antibiotic treatment for infections of Chlamydia pneumoniae has been associated with protection against myocardial infarction, probably via a stabilizing effect on the cytoskeleton of endothelial cells and on chondrocytes in humans. Dr Herings et al from the Netherlands decided to test this association through a case-control study to see whether patients receiving antibiotics for Chlamydia pneumoniae infections were less likely to have been admitted for a first acute MI (JAMA 2000 284:2998-2999)

Mummy's been given a toe job?

By | January 3, 2001

Research of human remains in the necropolis of Thebes-West suggests that ancient Egyptians were the pioneers of amputation and prosthetic surgery (Lancet 2000; 356: 2176-79).Professor Andreas Nerlich and colleagues from Ludwig-Maximilians-University, Munich, Germany, investigated the mummified remains of a woman aged about 50-55 who died between 1550 and 700 BC. Close pathological examination revealed that her right big toe had been amputated during her lifetime, because an intact layer of soft

Calling all binding sites

By | December 29, 2000

In the 22 December Science Ren et al. combine chromatin immunoprecipitation with DNA microarrays to identify all binding sites for two budding yeast transcription activators (Science 2000, 290:2306-2309). They start by breaking open cells, cross-linking bound protein to DNA, sonicating, and immunoprecipitating with an antibody against a particular transcription factor. The isolated DNA is amplified, and the abundance of the amplified fragments is compared with a whole genome amplification using

Keeping up the weight loss

By | December 29, 2000

Just in time for the New Year's resolution. A randomised, double blind trial suggests that the drug, sibutramine, previously known for inducing dose-dependent weight loss and enhancing the effects of a low-calorie diets, is effective in sustaining weight loss (Lancet 2000; 356: 2119-25). The international team of researchers, lead by Professor W Philip T James from Aberdeen, UK, studied 605 obese patients recruited from eight European centres. The patients were enrolled in a 6-month period of we

Inverted yeast

By | December 28, 2000

After comparing the genomic sequences of the two yeast species Saccharomyces cerevisiae and Candida albicans, Seoighe et al. report in the December 19 Proceedings of the National Academy of Sciences that gene adjacencies have been broken as frequently by small inversions as by translocations or long-distance transpositions (Proc Natl Acad Sci USA 2000, 97:14433-14437). Only 9% of gene pairs that are adjacent in one species are conserved as adjacent in the other, and the number of orientation cha
