A Case Report of Congenital Microtia-Atresia

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2021
Background and Objectives: Microtia-atresia is a rare congenital anomaly, which characterized by a small, abnormally shaped auricle (microtia) accompanied with narrow, blocked or absent ear canal (atresia). Microtia can occur appear either as independent

A wave-like anastomosis, a new technique of anastomosis to prevent stricture after oesophageal atresia repair

open access: yesAfrican Journal of Paediatric Surgery, 2021
Background: Anastomotic stricture still a frequent postoperative complication. Its development is multifactorial, nonetheless by improving some factors we can prevent the stricture.

Ovarian Matrisome Dynamics and αvβ3‐Mediated Regulation in Early Follicular Development

open access: yesAdvanced Science, EarlyView.
The matrisome undergoes dynamic remodeling during early follicular development. Integrin αvβ3 mediates matrisome signals, regulating primordial follicle activation/atresia and secondary follicle growth via Hippo/mTOR pathways, with conserved roles in human ovaries, offering therapeutic targets for ovarian disorders.

Sphingosine-1-phosphate and ceramide are associated with health and atresia of bovine ovarian antral follicles

open access: yesAnimal, 2015
The follicle destiny towards ovulation or atresia is multi-factorial in nature and involves outcries, paracrine and endocrine factors that promote cell proliferation and survival (development) or unchain apoptosis as part of the atresia process.

IGF‐1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response

open access: yesAdvanced Science, EarlyView.
IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture

open access: yesAdvanced Science, EarlyView.
Disrupted neurovascular coupling contributes to ovarian dysfunction in polycystic ovary syndrome. Using near‑infrared II long‑wavelength imaging, this study visualizes how electroacupuncture dynamically regulates ovarian blood vessels in vivo. Immediate and cumulative stimulation elicit distinct vascular responses via a Netrin‐1 dependent mechanism ...

Sulpiride-Induced Hyperprolactinemia in Mature Female Rats: Evidence for Alterations in The Reproductive System, Pituitary and Ovarian Hormones [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2014
Background The prevalence of hyperprolactinemia following administration of conven- tional antipsychotic drugs requires further investigation. The current study is designed to evaluate the effect of sulpiride (SPD)-induced hyperprolactinemia on ...

Evolutionary and ecological insights from vital staining of bivalve oocytes: A Red Queen at the sweepstakes?

open access: yesEcosphere, 2022
To determine the proportion of inviable oocytes that are spawned along with normal oocytes in marine bivalves, we turned to a time‐honored technique not previously used on invertebrate oocytes: the neutral red vital stain.

From Multiple Congenital Anomalies to Pituitary Gland Malformation: Wide Spectrum of Clinical Features in a Family With FOXA2 Variant

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT FOXA2 (hepatocyte nuclear factor‐3β, HNF‐3β) encodes a transcriptional activator involved in early embryogenesis, particularly in the patterning and differentiation of midline structures such as the neural tube, foregut, and pituitary gland. Its role in human pathogenesis was first suspected when patients with deletion of chromosome 20p11.2 ...
