Placental biomarker and fetoplacental Doppler abnormalities are strongly associated with placental pathology in pregnancies with small‐for‐gestational‐age fetus: prospective study

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective Placental dysfunction can result in small‐for‐gestational age (SGA) or fetal growth restriction (FGR). The aim of this prospective cohort study was to assess the association of the cerebroplacental ratio (CPR) and other more conventional fetoplacental Doppler indices, circulating placental growth factor (PlGF) levels and soluble fms ...

Semaglutide to remodel mitochondrial dynamics and mitophagy balance for vascular dementia therapy

VIEW, EarlyView.
The effects of semaglutide on IR, mitochondrial dynamics, and mitophagy in the hippocampus of BCAS mice after CCH. It was shown that semaglutide maintained the balance of mitochondrial dynamics and mitophagy by improving IR and passing through GLP‐1R/PI3K/Akt pathway, reduced hippocampal neuroinflammation and neuron loss, and thus promoted the recovery

General analysis of mathematical models for bone remodeling [PDF]

arXiv, 2010
Bone remodeling is regulated by pathways controlling the interplay of osteoblasts and osteoclasts. In this work, we apply the method of generalized modelling to systematically analyse a large class of models of bone remodeling. Our analysis shows that osteoblast precursors can play an important role in the regulation of bone remodeling.

Outcomes of Postpartum Preeclampsia: A Retrospective Cohort Study of 1.3 Million Pregnancies

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 132, Issue 6, Page 752-759, May 2025.
ABSTRACT Objective We assessed the association between postpartum preeclampsia and the risk of adverse maternal and neonatal outcomes. Evidence suggests that postpartum preeclampsia is initiated antenatally, but the impact on birth outcomes is unclear. Design Retrospective cohort study. Setting All deliveries in hospitals of Quebec, Canada.

An In‐Depth Analysis and Classification of Placental Causes of Stillbirth: A 10‐Year Retrospective Study of a Regional Stillbirth Registry

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Introduction Abnormal placental lesions are commonly identified in stillbirth. Interpreting these lesions and their contribution to fetal demise presents significant challenges. Recommended CODAC classification does not include detailed placental examination results.

Heat Stress and Placental Abruption: A Space–Time Stratified Case‐Crossover Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To examine whether heat stress, measured by wet bulb globe temperature (WBGT), a comprehensive heat stress index is associated with placental abruption within 7 days. Design A space–time‐stratified case‐crossover design. Setting All 11 regions in Japan during the warm season (June–September) from 2011 to 2020.

Endothelial damage and complement dysregulation in fetuses from pregnancies complicated by preeclampsia

Acta Obstetricia et Gynecologica Scandinavica, Volume 104, Issue 5, Page 829-838, May 2025.
Preeclampsia fetuses show an altered profile of endothelial damage and complement biomarkers, like increased adhesion molecules, prothrombotic state, oxidative stress, and reduced complement membrane attack complex deposition on endothelial cells. Abstract Introduction Our objective was to evaluate the endothelial function profile and complement system

ERNEST COST action overview on the (patho)physiology of GPCRs and orphan GPCRs in the nervous system

British Journal of Pharmacology, EarlyView.
G protein‐coupled receptors (GPCRs) are a large family of cell surface receptors that play a critical role in nervous system function by transmitting signals between cells and their environment. They are involved in many, if not all, nervous system processes, and their dysfunction has been linked to various neurological disorders representing important
