Aseptic Tibial Loosening Is Associated With Thickness of the Cement: A Radiographic Case-Control Study.

Background: The cementation technique is crucial for achieving adequate fixation and optimal survivorship in total knee arthroplasty (TKA). The thickness of the cement at the tibial bone-implant surface may be related to aseptic tibial loosening. However, to date, no studies have demonstrated a direct association between cement thickness and rates of aseptic tibial loosening.

The endangered common hamster needs proteins: identifying diversified crop-based diets improving hibernation and reproductive success.

Modern production-oriented farming has led to a decline in agricultural biodiversity. In Europe, one example of concern is the common hamster , a hibernating rodent once largely distributed in farmlands and now listed as Critically Endangered. The decline of this species is tied to a significant decrease in hamsters' body mass at emergence from hibernation and in reproduction rate.

Fungal nasal polyposis - A rare case report.

Aspergillus peyronelii is an emerging and rare pathogen causing chronic rhinosinusitis with fungal nasal polyposis among immunocompetent individuals. Usual fungal aetiologies are Aspergillus spp, Mucor spp and Cladosporium spp, among which Aspergillus flavus being the most common in India. We present a case of 28-year-old woman with unilateral nasal obstruction with 15 years history of allergy, diagnosed as nasal polyposis, uncovered an uncommon pathogen A.

Drying out fish ponds, for an entire growth season, as an agroecological practice: maintaining primary producers for fish production and biodiversity conservation.

Agroecology largely focusses on terrestrial agroecosystems, but it can also be applied to fish farming. Indeed, ponds are typically used for fish production in Europe, but are also important reservoirs of biodiversity. Numerous studies demonstrate that both fish production and biodiversity are strongly determined by human management.
