objective: mitochondria is a critical organelle within the cell and has important role in the oocyte development, thus the aim of this study was the comparison of mitochondrial distribution within the mouse oocyte at germinal vesicle (gv), germinal vesicle breakdown (gvbd) and metaphase ii (mii) stages using laser confocal microscopy (lscm). materials and methods: after superovulation of adult...

Biomimetic vesicle prototissues have been designed as a model for cellular tissues. Prototissues display spheroidal or sheet like morphologies, and predictable vesicle–vesicle adhesion strengths, typical sizes, degree of compaction.

Sakuma and Imai [Phys. Rev. Lett. 107, 198101 (2011)] established a temperature-controlled cyclic process for model system of self-reproducing vesicles without feeding. The vesicle generates smaller inclusion called "daughter vesicle" inside the original (we call this "mother vesicle") then daughter is expelled through small pore on mother vesicle. This birthing. In present study we theoretical...

background: cryopreservation and in vitro maturation (ivm) of oocyte is becoming an important technique in infertility treatment and fertility preservation. also it has been proposed to establish a genetic resource bank for endangered or commercially important animal species. objective: the aim of this study was to evaluate viability, maturation and fertilization rate of mouse immature oocytes ...

A self-propelled Janus colloid performs a persistent orbital motion around giant unilamellar vesicle, even when the vesicle size is comparable to particle size.

methods mycobacterium tuberculosis standard strain crbip7.11 was cultured at 37°c in loewenstein johnson (lj) media for 3-4 weeks. to confirm the species, standard microbiological and biochemical tests were performed. after preparation of membrane vesicles, the amount of protein in membrane vesicles was measured by sds-page and nanodrop. to analyze the integrity and morphology of extracellular ...

Front Cover In article number 2200881, Lei, Guo, and co-workers modified the experimental analytical methods of single cell sequencing to extracellular vesicle, then characterized high-throughput transcriptome at vesicle level for first time.

background: superficial mucocele presents as small, clear vesicle on noninflamed mucosa. in this study, we report several vesicles on the bucal mucosa of a woman diagnosed as superficial mucocele.case presentation: a 48-year old woman presented with multiple vesicles on her labial mucosa, ventral surface of the tongue, floor of the mouth and palate. a mucosal biopsy was taken from the vesicle. ...

the changes of total calcium content of persian sturgeon, acipenser persicus follicles were investigated during different stages of germinal vesicle migration. total calcium content increased during maturation and ripening of the oocytes i.e. migration of nucleus toward the animal pole. according to data, the total calcium of follicles with polarization index (pi: the ratio of the distance of t...
