WORLD OF REPRODUCTIVE BIOLOGY: Progesterone and Endocannabinoid Interaction Alters Sperm Activation

A recent study in Science finds that α/β-hydrolase domain-containing protein 2 (ABHD2) is a novel nongenomic progesterone receptor that holds the CatSper cation channel open while progesterone elevates sperm cytoplasmic calcium ion (Ca) levels and triggers sperm hyperactive motility. ABHD2 functions as a lipid hydrolase, breaking down arachidonoylglycerols (2-AG/1AG)—endocannabinoid components ...

what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...

Cranes of the World: 5. Comparative Reproductive Biology

Congenital myopathy with cytoplasmic bodies.

Since early infancy, a 15-year-old girl had suffered from an apparently static neuromuscular disorder that chiefly afflicted her proximal muscles but did not spare her distal ones. Her CPK values had repeatedly been mildly elevated and her electromyogram had been considered "myopathic". There were no similar neuromuscular disorders in the family. Quadriceps muscle biopsy showed a type I myofibe...

Reproductive biology of Mossul bleak (Alburnus mossulensis) in Bibi-Sayyedan River of Tigris basin in Iran

Reproductive characteristics of Mossul bleak, Alburnus mossulensis, a native species of Cyprinidae family in Bibi-Sayyedan River of Semirom, Isfahan, were investigated by monthly sampling during December 2010 to December 2011. Five hundred and fourty three specimens (256 females, 159 males and 31 immature) were caught by a sein net (5 mm mesh size). The collected sampeles were anesthesized in 1...
