Quality of Semen Stored in On-the-Farm Semen Tanks
We assessed the damage to frozen semen packaged in French straws stored for 2 yr in 60 on-the-farm semen tanks on 56 Washington dairy farms. Percentage of motile spermatozoa and percentage of spermatozoa with intact acrosomes were not affected significantly by position of the semen on the rack (top or bottom goblet).

Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...

Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...
