ABSTRACT The nuclear steroid hormone receptor progesterone receptor (PGR) is expressed in granulosa cells in the ovarian follicle in a tightly regulated pattern in response to the surge of luteinizing hormone (LH) that stimulates ovulation. PGR plays a critical role in mediating ovulation in response to LH, however, the mechanism for this is still ...

Using Atomic Force Microscopy, the link between oocyte mechanical properties and actin cortex organization is investigated. In mouse oocytes, a thin actin cortex results in stiffer oocytes, while a thicker cortex leads to softer ones. Maternal age affects oocyte mechanics by altering cortex structure.

Isolated asthenozoospermia: What should we know? A narrative review of literature
ABSTRACT Male infertility contributes to 20%–70% of infertile couple cases worldwide. One of the key challenges in this area is asthenozoospermia or reduced sperm motility. A particular subset, known as isolated asthenozoospermia (iASZ), in which low motility occurs without abnormalities in sperm count or shape, often goes unnoticed and is not well ...

Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

ABSTRACT Women's reproductive rights in China are shaped by geopolitical and cultural factors, resulting in restricted access to planned oocyte cryopreservation (planned OC). While the global discourse surrounding planned OC continues to evolve, China currently sanctions egg freezing for medical purposes exclusively in married women, while prohibiting ...

Comparison of Luteal Support Protocols in Frozen IVF/ICSI Cycles: A Network Meta‐Analysis
ABSTRACT Background Luteal support is a core success factor of frozen embryo transfers (FET). However, inconsistency across recommended protocols generates notable heterogeneity across reproductive outcomes. Objective To determine the most effective luteal support strategy (LPS) based on five key factors related to the effectiveness of FET cycles ...

This study introduces a microinjection technique to deliver dsRNA into the hemolymph of first instar larval thrips (L1s) via the foreleg coxa, enhancing survival rates by minimizing internal tissue damage. Significant knockdown of V‐ATPase‐B, CYP3653A2, and ApoLp‐II/I was achieved, with silencing of CYP3653A2 or ApoLp‐II/I increasing larval mortality ...

Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of
