Temporal regulation of endoderm convergence and extension by the BMP activity gradient through mesoderm-dependent and independent mechanisms.

One hundred years ago, Spemann and Mangold identified the organizer, a critical embryonic region that establishes vertebrate body axes by directing cell fate and morphogenesis. A conserved vertebrate mechanism involves the regulation of a ventral-to-dorsal BMP activity gradient during gastrulation by the organizer-expressed molecules. In zebrafish, BMP signaling controls mesodermal cell convergence and extension (C&E) by inhibiting Planar Cell Polarity (PCP) signaling and regulating cell adhesion.

Unravelling riverine dissolved organic matter sources using molecular fingerprints and FEAST model in a multi-tributary mountain river basin.

Revealing the sources, composition and fate of riverine dissolved organic matter (DOM) is fundamental to understanding the biogeochemical cycles of aquatic ecosystems. This study aimed to reveal the impact of land uses and wastewater treatment plants (WWTPs) on riverine DOM. Spatiotemporal variations in molecular characteristics of riverine DOM in the river network containing 15 tributaries in the mainstream of upper Hanjiang River were studied.

Dynapenia is associated with a higher risk of depressive symptoms among older adults.

Background: Depression affects the global burden of disability among older adults. Although dynapenia is related to disability and potential psychological health outcomes, its association with depressive symptoms remains uncertain. Accordingly, the objective of the current study was to investigate this association in older Taiwanese adults, applying the 2019 Asian Working Group for Sarcopenia (AWGS) classification of dynapenia.

Comparison of 3D and 2D area measurement of acute burn wounds with LiDAR technique and deep learning model.

It is generally understood that wound areas appear smaller when calculated using 2D images, but the factors contributing to this discrepancy are not well-defined. With the rise of 3D photography, 3D segmentation, and 3D measurement, more accurate assessments have become possible. We developed an application called the Burn Evaluation Network (B.

Exploring the interplay between mitochondrial dysfunction, early life adversity and bipolar disorder.

Objective: Mitochondria are essential for energy production and reactive oxygen species (ROS) generation, with changes in ROS levels or energy demands affecting mitochondrial DNA (mtDNA) copy numbers, indicating mitochondrial function. Early life adversity (ELA) affects mitochondrial dynamics, influencing long-term health. Both ELA and mitochondrial abnormalities have been independently associated with bipolar disorder (BD).
