Congenital Bilateral Mid Ureteral Stenosis: A Rare Finding.

Bilateral congenital mid ureteric stenosis is a very rare entity causing hydroureteronephrosis. The pathophysiology and aetiology of this condition is uncertain. Congenital functional obstruction of the mid ureter has only 17 reported cases, that too of unilateral pathology.

Biodegradation of diesel oil by an Arabian Sea sediment culture isolated from the vicinity of an oil field.

Laboratory scale batch studies were performed to test the diesel oil biodegradation ability of ES1 cultures isolated from Arabian Sea sediments obtained from the vicinity of an oil field. This culture could utilize diesel as the sole source of carbon and energy. Under aerobic conditions, 39% loss of diesel oil was observed over 8 days where 80% of the loss was due to aliphatic constituents.
