m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

Advanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

Doppler sonar analysis of swallowing sounds in normal pediatric individuals Análise dos sons da deglutição pelo sonar Doppler em indivíduos normais na faixa etária pediátrica

Brazilian Journal of Otorhinolaryngology, 2009
Among the methods for assessing swallowing sounds - videofluoroscopy modified barium study, fiberoptic swallowing endoscopy, neck auscultation through a microphone, accelerometer and, more recently, the Doppler sonar - we have chosen the latter.

A Micropeptide Component of the OGDH Complex Modulates ATP Production in the TCA Cycle

Advanced Science, EarlyView.
This study identified a mitochondrial micropeptide encoded by a non‐canonical open reading frame (alt‐ORF) within the CTSB gene. This micropeptide named APPM (ATP production‐promoting micropeptide) is a novel component of the OGDHc complex in the TCA cycle. APPM localizes to the inner mitochondrial membrane and directly binds to OGDH, the E1 subunit of

An RNA‐Binding Protein RBMS1 Promotes Endothelial Cell Autophagy to Maintain Vascular Homeostasis and Suppress Deep Vein Thrombosis

Advanced Science, EarlyView.
RBMS1, an RNA‐binding protein, restores vascular endothelial homeostasis by enhancing ATG3‐mediated autophagy, thereby attenuating thrombus formation and suggesting a potential avenue for further therapeutic exploration in DVT. ABSTRACT Deep vein thrombosis (DVT) is a prevalent vascular disorder characterized by aberrant coagulation within the deep ...

Magnetostriction quasi-static measurements with laser Doppler effect

工程科学学报, 2016
A quasi-static method for measuring the magnetostrictive coefficient of Fe-Ga alloys by using laser Doppler effect was put forward, and its working principle was also analyzed. The quasi-static magnetostrictive coefficient of Galfenol was measured.

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

Advanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...
