SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

Advanced Science, EarlyView.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Evaluation of the effectiveness and cost of different hormones in stimulating the spawning of thin lipped grey mullet, Liza ramada [PDF]

The Egyptian Journal of Histology, 2018
Introduction: It is known that mullets are not fully mature in captivity and therefore do not lay eggs. Therefore, hormonalpreparations should be used to stimulate spawning.Aim of the work: To evaluate the effectiveness and cost of using different types ...

Compact 9dBEs Enable Efficient and Precise Genome Editing in Mammalian Cells and In Vivo

Advanced Science, EarlyView.
As a compact type II‐D system, the Cas9d‐based platform holds great potential for in vivo applications. Through rational engineering, its derived base editors (9dBEs) enable efficient disease modeling while facilitating single‐vector AAV delivery for in vivo genome editing. These miniature tools offer a robust strategy for basic research and biomedical

Expanded Phenotype Associated With an Intronic PPP1R12A Variant: A Case Report and Literature Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal dominant PPP1R12A‐related genitourinary and/or brain malformation syndrome is a recently described multisystem disorder caused by loss‐of‐function variants in the protein phosphatase 1 regulatory subunit 12a (PPP1R12A) gene. To date, 22 affected individuals have been reported with variable brain malformations and genitourinary ...

Similar risk for hemangiomas after amniocentesis and transabdominal chorionic villus sampling [PDF]

, 2012
Aim: In an earlier study we have shown that transcervical chorionic villus sampling in excess of 90 mg increases the risk for hemangiomas of infancy three- to four-fold compared to amniocentesis.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not
