Role of GPR55 receptor in bovine sperm capacitation.

Background: Endocannabinoids like anandamide (AEA), among other lipids, are recognized signaling molecules that participate in reproductive events.

Objectives: Our aims were to characterize orphan G protein-coupled receptor (GPR55) presence; investigate GPR55 activation by AEA and determine GPR55 role in the bovine sperm function.

Materials And Methods: GPR55 presence was assessed by immunocytochemistry.

Development and growth of bovine calves demi-embryos.

The aim of this study was to investigate the growth and development of animals produced from demi-embryos and compare them with whole embryos from fetus to adult life. To achieve this, calves produced from fresh demi-embryos and whole embryos were individually transferred and monitored from 60 days of pregnancy until slaughter at 550 days. Ultrasound scans were conducted on fetuses at 60 and 90 days to evaluate the biparietal, abdominal, umbilical cord, orbital, and aorta diameters.

[Active properties and therapeutic effects of San Giovanni Spa mud (Portoferraio, Elba Island)].

The authors describe the most important chemical-physical characteristics of the slime of the Terme San Giovanni in Elba Island, both with reference to the inorganic component, and especially to the organic one. The latter principally comes from the presence in the extraction basin of green algae of Caulerpa genus and of two sea plants, Zoostera marina and Posidonia oceanica. The presence of sulphur, in the organic components of slime, and of iron, in the inorganic one, provide the peloid peculiar properties which are very interesting in the treatment of dermatological diseases.
