Effect of Mechanical Micro-Vibrations on The Efficiency of Leopard Inter-Species Somatic Cell Nuclear Transfer [PDF]

Cell Journal, 2022
Objective: Scarcity of oocytes for assisted reproduction in endangered species can be bypassed by interspecies somatic cell nuclear transfer (iSCNT). In Felids, domestic cat (Felis catus) oocytes can serve as recipients for the nucleus of the endangered ...

Precise mimicry of physiological Ca²⁺ oscillations for mammalian oocyte activation by nanosecond pulsed electric field. [PDF]

Bioeng Transl Med
Oocyte activation deficiency is a primary cause of fertilization failure following intracytoplasmic sperm injection, a problem that can potentially be overcome through artificial oocyte activation (AOA). However, concerns persist regarding the safety and

P-218 Does Artificial Oocyte Activation (AOA) improve the outcome beyond fertilization rate in ICSI cycles?

Human Reproduction, 2023
Does CultActive© improve reproductive outcomes of ICSI cycles in cases of low fertilization rate and normal fertilization rate? The application of CultActive© after ICSI improves fertilization rates only in clinical indication of ...

Are physiological oscillations physiological?

The Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

In vitro Activation of mouse oocytes through intracellular Ca2+ regulation

Journal of Human Reproductive Sciences, 2020
Background: Ca2+ signaling pathway is suggested to play an essential role in mediating oocyte maturation. Aims: The aim of this study was to evaluate intracellular Ca2+ of resistant immature oocytes that failed to resume meiosis following subsequent in ...

Sperm-oocyte interplay: an overview of spermatozoon’s role in oocyte activation and current perspectives in diagnosis and fertility treatment

Cell & Bioscience, 2021
The fertilizing spermatozoon is a highly specialized cell that selects from millions along the female tract until the oocyte. The paternal components influence the oocyte activation during fertilization and are fundamental for normal embryo development ...

Functional Roles of Src Kinase Activity in Oocyte Maturation and Artificial Egg Activation in <i>Xenopus laevis</i>. [PDF]

Cells
Src family tyrosine kinases regulate oocyte maturation and fertilization in many species, yet their physiological roles in Xenopus laevis (X. laevis) remain incompletely defined. Here, we generated three X. laevis Src (xSrc) constructs with defined point
