The discovery of Meloidogyne mayaguensis is confirmed in Florida; this is the first report for the continental United States. Meloidogyne mayaguensis is a virulent species that can reproduce on host cultivars bred for nematode resistance. The perineal patterns of M. mayaguensis isolates from Florida show morphological variability and often are similar to M. incognita. Useful morphological chara...

The purpose of this study was to evaluate the use of glass capillary micropipette (GCM) as a vessel forvitrification of bovine oocytes. Cumulus-oocyte complexes (COCs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (TCM-199 + 20% FBS) and randomly assigned to treatment andcontrol group. In the first step of vitrification, COCs were exposed to first vitrification...

background: retinoids have been suggested to play a role in oogenesis and oocyte survival. objective: in the present study the effects of retinol palmitate were investigated on differential follicular counts in response to superovulation as well as follicle quality after vitrification of ovaries. materials and methods: ten, 4 week old female balb/c mice were randomly assigned to either paraffin...

Background: Cryopreservation of ovary for preserving germ cell line is going to be an important issue. However, the physical and chemical stresses during cryopreservation are the most important factors that may influence the post freezing tissue viability and quality. Vitrification is a new approach to bypass the impacts of both stresses for gametes and embryos and it is also suggested for ovar...

Engineering practitioners commonly use penetration-based methods (SPT & CPT) for assessment of seismic liquefaction triggering hazard. On the horizon, shear wave velocity (Vs) may offer engineers a third tool that is lower cost and provides more physically meaningful measurements. Development of the shear wave velocity liquefaction method has been hampered by a paucity of published velocity pro...

Background: The development of a reliable method for the cryopreservation of mammalian ovary would be an important advancement in the field of reproductive biology for the preservation of genetic resources. The cryopreserved follicles have the potential to develop in-vitro; however, the developmental rate is lower than that of fresh follicles. Researchers have used that of different cryoprotect...

Background Whole ovary cryopreservation has been proved to be a feasible technique in fertility preservation. The normal ovarian cortex contains a large population of primordial follicles, this characteristic make them far more tolerant to cryoinjury. Researchers have used different cryoprotectants and various techniques to improve cryopreservation. It is plausible that inclusion of an antioxid...

Background Follicle cryopreservation has been proposed as an alternative fertility preservation option. Follicles can be cryopreserved in intact ovarian tissue pieces or after isolation of individual follicles from the fresh ovarian tissue using enzymatic or mechanical techniques. Researchers have used different cryoprotectants and various techniques to improve cryopreservation. It is plausible...

Background: Cryopreservation of ovarian tissue is an important option for preserving the fertility of cancer patients undergoing chemotherapy and radiotherapy. Researchers have used different cryoprotectants and various techniques to improve the cryopreservation of ovaries However, despite significant recent progress, the efficiency of ovary cryopreservation is still low. Zinc is essential for ...
