Many animals undergo changes in functional colors during development, requiring the replacement of integument or pigment cells. A classic example defensive color switching is found hatchling lizards, which use conspicuous tail to deflect predator attacks away from vital organs. These usually fade concealing ontogeny. Here, we show that ontogenetic blue-to-brown change Acanthodactylus beershebensis lizards results changing optical properties single types developing chromatophore The blue...
Exogenous arachidonic acid induces the acrosome reaction and production of prostaglandins PGE2 PGF2 alpha in bovine spermatozoa. also synthesis. To understand better role induction synthesis through modulation phospholipase A2, inhibitors this enzyme were used. The effects blocked by A2 inhibition was reversed addition acid. These data indicate that activates to produce determine whether protein kinase C modulates activity process, staurosporin, an inhibitor C, effect on is inhibited...
Abstract Many animals undergo dramatic changes in colour during development 1,2 . Changes predation risk ontogeny are associated with spectacular switches defensive colours, typically involving the replacement of skin or production new pigment cells 3 Ontogenetic systems ideal models for understanding evolution and formation mechanisms animal which remain largely enigmatic 2 We show that switching lizards arises by reorganization a single photonic system, as an incidental by-product...
Foetal gonads were obtained from 1) 8 male foetuses that co-twin to freemartins, 2) isosexual twins, 3) 59 singletons of 45-75 days gestations, 4) 5 and co-twins 90-120 5) freemartins at 70-120 gestation. The incubated in supplemented medium 199 for 24 h the absence or presence LH testosterone progesterone produced measured by RIA. During time sexual differentiation (45-75 days) testes significantly less than same age. Testes older 90 refractory LH-stimulation, but freemartin ovaries their...
