The primary optic system in a microphthalmic snake (Calabaria reinhardti)

, : The primary optic system in a microphthalmic snake (Calabaria reinhardti). Brain Research 408(1-2): 233-238

The retinal projections in the microphthalmic snake Calabaria reinhardtii were investigated by means of the radioautographic method following intraocular injections of [3H]proline. The results demonstrated the existence of a general pattern of organization of the primary visual system comparable to that observed in macrophthalmic snakes. However, most of the primary optic centers appeared reduced and showed varying signs of atrophy, whereas others were completely absent. Elsewhere, the ipsilateral visual component appeared as well developed as that found in macrophthalmic snakes. The evolutionary significance of the differential microphthalmic pattern of organization of the primary visual system is discussed.

Linker histones (LHs) bind to the DNA entry/exit points of nucleosomes and demonstrate preference for AT-rich DNA, although the recognized sequence patterns remain unknown. These patterns are expected to be more pronounced in metazoan nucleosomes...

The aim of the study was to evaluate berberine-induced bidirectional regulation on the contractility of jejunum. Different low and high contractile states of isolated jejunal segment from rat were established to investigate the effects of berberin...
