DNA Deletion Makes Swedish Chlamydia 'Invisible'
New sequencing and analysis of six strains of Chlamydia will result in improved diagnosis of the sexually transmitted infection. This study provides remarkable insights into a new strain of Chlamydia that was identified in Sweden in 2006 after spreading rapidly across the country by evading most established diagnostic tests.

New Data From Satraplatin Phase 3 Trial In Second-Line Castrate-Refractory Prostate Cancer Presented At 2009 ASCO Annual Meeting
GPC Biotech AG (FRANKFURT: GPC) (XETRA: GPC) announced that data from the double- blind, randomized satraplatin Phase 3 trial, the SPARC trial (Satraplatin and Prednisone Against Refractory Cancer), were presented at the 2009 American Society for Clinical Oncology (ASCO) Annual Meeting in Orlando, Florida. The SPARC trial evaluated satraplatin plus prednisone versus placebo plus prednisone in 950 patients with castrate-refractory prostate cancer (CRPC) who had progressed after initial chemotherapy. The data presented are retrospective analyses of the SPARC trial evaluating correlations between overall survival (OS) and pain at baseline, pain progression, and progression-free survival (PFS) at three months.

Associative Sequence Learning: The Role Of Experience In The Development Of Imitation And The Mirror System

The ability to imitate is crucial for human social interaction and cultural inheritance. Until recently, it was assumed that this ability was innate. We review new evidence indicating that experience plays a critical role in the development of imitation. The brain"s "mirror system" represents both observed and performed actions. We show that disrupting the function of the inferior frontal gyrus, a mirror system area, interferes with automatic imitation of finger movements. This indicates that the mirror system is causally involved in generating imitative behaviour. We conclude that sensorimotor experience is essential for the development of imitation and the mirror system. Royal Society Journal
