How does the storage volume of semi-arid reservoirs change water quality and modulate the diversity of benthic macroinvertebrates?

In the current environmental crisis scenario, it becomes increasingly important to understand the hydroclimatic effects on the availability and quality of water resources and their impacts on aquatic biodiversity. The understanding of how these components are interconnected is necessary to support initiatives for monitoring and managing water resources and protecting biodiversity. In this study, we analyzed the hierarchical effects and dissociated the complex relationships between the storage volume of tropical semi-arid reservoirs on water quality and the diversity of benthic macroinvertebrates.

Unravelling spermatogenesis in spotted wolffish: Insights from the ultrastructure of juvenile male testes to the cryopreservation of broodstock sperm.

The aim of this study was to deepen our understanding of the reproductive biology of male spotted wolffish () using two different experimental approaches involving juvenile and mature broodstock fish. The first approach consisted of a detailed histological examination of the testes to identify the onset of gonadal maturation and characterise the spermatogenic stages in two- and three-year-old juvenile specimens. Light microscopy analysis revealed clear differences between the age groups.

Enhancing the light yield of He:CF based gaseous detector.

The CYGNO experiment aims to build a large ( m ) directional detector for rare event searches, such as nuclear recoils (NRs) induced by dark matter (DM), such as weakly interactive massive particles (WIMPs). The detector concept comprises a time projection chamber (TPC), filled with a He:CF 60/40 scintillating gas mixture at room temperature and atmospheric pressure, equipped with an amplification stage made of a stack of three gas electron multipliers (GEMs) which are coupled to an optical readout. The latter consists in scientific CMOS (sCMOS) cameras and photomultipliers tubes (PMTs).

Day-case artificial urinary sphincter for post-prostatectomy incontinence: A comparative pilot study.

Objectives: Implantation of an artificial urinary sphincter (AUS) to treat post-prostatectomy incontinence (PPI) has been traditionally offered with an overnight hospital stay. The aim of this prospective, comparative pilot study was to assess the feasibility and outcomes of the AUS procedure in a day-case setting.

Patients And Methods: We included consecutive patients having primary or redo AUS surgery over an 18-month period.
