Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

ERK MAP kinases regulate smooth muscle contraction in ovine uterine artery: effect of pregnancy

, 2002
The present study investigated the potential role of extracellular signal-regulated kinase (ERK) in uterine artery contraction and tested the hypothesis that pregnancy upregulated ERK-mediated function in the uterine artery. Isometric tension in response

Personalized Gamified Learning in a Course on the Urogenital System Anatomy: Differential Effects Across Learning Preference Profiles

Clinical Anatomy, EarlyView.
ABSTRACT Personalized learning approaches adapted to individual metacognitive characteristics have demonstrated promise in Anatomy education. However, whether such benefits are uniform across learner profiles or vary systematically remains an open question with implications for individualized instructional approaches.

Characterization and automatic classification of preterm and term uterine records. [PDF]

PLoS ONE, 2018
Predicting preterm birth is uncertain, and numerous scientists are searching for non-invasive methods to improve its predictability. Current researches are based on the analysis of ElectroHysteroGram (EHG) records, which contain information about the ...

Uterine contraction and physiological mechanisms of modulation

, 1993
Control of the smooth muscle in the uterus (the myometrium), is of vital importance during pregnancy and parturition. It is therefore understandable that several physiological mechanisms (neuronal, hormonal, metabolic, and mechanical) play a role in the ...

Phloroglucinol inhibits oxytocin-induced contraction in rat gastric circular muscle and uterine smooth muscle

, 2022
Phloroglucinol is commonly used to alleviate dysmenorrhoea and stomach cramps. However, there is little evidence of phloroglucinol in the mechanism of primary dysmenorrhoea (PD) development. In this study, a PD rat model was established.

From Metabolic Crisis to Molecular Classification: Multidisciplinary Management of Synchronous Endometrioid Ovarian and Endometrial Carcinomas With Massive Tumor Burden

Cancer Nexus, EarlyView.
Managing massive tumor burden in synchronous endometrioid carcinomas. The graphical abstract summarizes the clinical pathway from presentation with massive ascites, pleural effusion, and critical metabolic abnormalities to multidisciplinary stabilization, surgical management, integrated morphologic–molecular classification, and shared decision‐making ...

Piezo1 overexpression in the uterus contributes to myometrium contraction and inflammation-associated preterm birth

Journal of Translational Medicine
Background Preterm birth, a leading cause of perinatal mortality and morbidity, is often associated with inflammation and aberrant myometrial contractions.

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

Developmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...

Impact of donor mare and stallion identity on the likelihood of pregnancy after transfer of in vitro produced embryos

Equine Veterinary Journal, EarlyView.
Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...
