Objective- The aim of this study was to determine the first possible time for pregnancy recognition and several features of developing embryo between days 8 to 44 of pregnancy. Design- Experimental study Animals- Six healthy registered Caspian mares Procedures- Daily ultrasound examinations were conducted from days 8 to 44 (ovulation = day 0) of pregnancy to monitor the conceptus in Caspian ...

Background: To report a rare case of a left ejaculatory duct that allotropically protrudes or invades towards the left vesicle triangular area with its dead end. Materials and Methods: The patient simultaneously exhibited multiple congenital malformations of the homolateral urogenital system, such as the absence of a left kidney, the dysplasia and allotopia of the left seminal vesicle, the abse...

PURPOSE Reorganization of cytoskeleton and membrane biogenesis are dynamically coordinated during lens fiber cell differentiation and development to produce an organ with precise dimensions and optical properties. Cargo vesicle trafficking is fundamental to cell elongation and has also been implicated in degenerative disease mechanisms. Alzheimer precursor protein (AbetaPP) acts with kinesin, s...

Describe the embryonic development of Paralabrax humeralis (Peruvian rock seabass) and present morphology its eggs yolk-sac larvae using spawned by P. broodstock in captivity. The spawning occurred naturally spontaneously early November 2018. egg is pelagic round, with a diameter 0.98 ± 0.02 mm, an oil globule, 0.2 mm. Embryonic started meroblastic cleavage, reaching first cleavage stage at 0.4...

Exocytosis of synaptic vesicles requires the formation of a fusion complex consisting of the synaptic vesicle protein synaptobrevin (vesicle-associated membrane protein, or VAMP) and the plasma membrane proteins syntaxin and soluble synaptosomal-associated protein of 25 kDa (or SNAP 25). In search of mechanisms that regulate the assembly of the fusion complex, it was found that synaptobrevin al...

Dorsal and ventral specification in the early optic vesicle appears to play a crucial role in the proper development of the eye. In the present study, we performed embryonic transplantation and organ culturing of the chick optic vesicle in order to investigate how the dorsal-ventral (D-V) polarity is established in the optic vesicle and what role this polarity plays in proper eye development. T...
