Retroperitoneal filariasis diagnosed by fine needle aspiration: a case report.

Background: Filarial worms lodge anywhere, from body fluids to subcutaneous tissue, as various case reports prove.

Case: A 21-year-old Nepali male presented with bilateral groin swellings. Imaging studies showed dilated retroperitoneal lymphatics forming a mass, suggestive of lymphangioma or lymphangioleiomyoma.

Interaction of genetic and environmental factors in Saccharomyces cerevisiae meiosis: the devil is in the details.

One of the most important principles of scientific endeavour is that the results be reproducible from lab to lab. Although research groups rarely redo the published experiments of their colleagues, research plans almost always rely on the work of someone else. The assumption is that if the same experiment were repeated in another lab, results would be so similar that the same interpretation would be favoured.

Cryopreserved recombinant tissue plasminogen activator for the restoration of occluded central venous access devices in pediatric oncology patients.

Background: Thrombolytic therapy with urokinase 5000 units has been the standard therapy for the restoration of thrombosed central catheters. However, with the decreased availability of urokinase, alternatives needed to be sought. The aim of the study was to determine the efficacy, bioactivity, dwell time and cost of cryopreserved recombinant tissue plasminogen activator (rTPA) in the restoration of occluded central venous access devices.
