National human embryo and embryoid research policies: a survey of 22 top research-intensive countries.

Regenerative medicine, 2020
Research using human embryos and embryoids has expanded in recent years due to technological advances. Surveying laws and guidelines among the top research and development (R&D) investing nations highlights existing barriers to expanding this area of ...

Correction to: Expression of factors involved in apoptosis and cell survival is correlated with enzymes synthesizing lysophosphatidic acid and its receptors in granulosa cells originating from different types of bovine ovarian follicles

Reproductive Biology and Endocrinology, 2017
Correction After publication of the original article [1] it was noted that the caption of Table two was incorrect. This caption should read “Distribution of ovarian follicles depending on the type (healthy, transitional, and atretic) Small superscript ...

Comparative Expression Analysis of HSP70, HSP90, IL-4, TNF, KITLG and KIT-receptor Gene between Varicocele-Induced and Non-Varicocele Testes of Dog [PDF]

International Journal of Fertility and Sterility, 2017
Background This study was designed to create an experimental varicocele model by a simple surgical procedure in dog with minimum invasion and to investigate the effect of varicocele-induced infertility on the expression of six related genes (HSP90, HSP70,

The effect of prednisolone on sperm viability, sperm penetration rate and intra-uterine insemination rates in men with marked sperm agglutination and antisperm antibodies

مجلة كلية الطب, 2005
Summary: Background: the immune system differentiates between the endogenous and exogenous bodies that inter the body. The break-down of blood-testis barrier results in the production of antisperm antibodies. This may occur in the case of an infection to

mRNA active transport in oocyte-early embryo: 3D agent-based modeling [PDF]

arXiv, 2023
Axes of polarity (and primary morphogenetic gradients) are established in the oocyte - early embryo through active transport and localization of maternal factors. It is the oocyte - syncytial embryo of Drosophila (D. melanogaster) that is a model object for studying the molecular machinery of such transport systems.

Prostaglandin F2α (PGF2α) production possibility and its receptors expression in the early- and late-cleaved preimplantation bovine embryos

BMC Veterinary Research, 2019
Background Prostaglandin F2α (PGF2α) is an important component for the physiology of female reproductive processes. In the literature, the data pertaining to the synthesis and action of PGF2α in early embryonic bovine development are limited.

Two-exponential models of gene expression patterns for noisy experimental data [PDF]

Journal of Computational Biology (2018) Vol. 25, No. 11, p. 1220-1230, 2017
Motivation: Spatial pattern formation of the primary anterior-posterior morphogenetic gradient of the transcription factor Bicoid (Bcd) has been studied experimentally and computationally for many years. Bcd specifies positional information for the downstream segmentation genes, affecting the fly body plan.
