Plastic-Degrading Microbial Consortia from a Wastewater Treatment Plant.

Plastic waste pollution has become a global crisis, with millions of tons of plastic expected to accumulate in landfills and in natural environments, posing a serious threat to wildlife and human health. As current recycling methods remain inefficient, there is an urgent need for innovative enzymatic solutions to break down plastics and enable a circular economy approach. In this study, we explore the plastic-degrading potential of microorganisms enriched from activated sludge (AS) sourced from a municipal wastewater treatment plant (WWTP)-a known microplastic-contaminated industrial niche.

Measurement of 5-androsten-3beta,17beta-diol in spermatic and peripheral venous blood samples from the same human subjects by a radioimmunoassay method.

An original method for 5-androsten-3beta,17beta-diol (A-diol) measurement using an antiserum against A-diol-16-CMO-BSA is described. A-diol and testosterone (T) were determined by radioimmunoassay methods in spermatic and peripheral venous plasma of nine normal subjects during surgical intervention for inguinal hernia repair. In spermatic venous plasma the levels of T and A-diol were, respectively, 25.

[Pulmonary arteriovenous fistula within the picture of congenital angiodysplasias. Clinical case].

The aetiopathogenesis, clinical picture, diagnosis and treatment of pulmonary arteriovenous fistula are examined in the light of a case observed at the Florence University Surgery Clinic in 1970 and marked by multiple truncular fistulae at the middle and inferior lobes of the right lung. The condition is seen as an instance of congenital angiodysplasia with arteriovenous shunt. A clear distinction is drawn between true fistulae, as seen in the reported case, and angioma and aneurysm.
