Novel predictive biomarkers for atonic postpartum hemorrhage as explored by proteomics and metabolomics.

Background: Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide, with uterine atony accounting for approximately 70% of PPH cases. However, there is currently no effective prediction method to promote early management of PPH. In this study, we aimed to screen for potential predictive biomarkers for atonic PPH using combined omics approaches.

Catalytic-independent functions of the Integrator-PP2A complex (INTAC) confer sensitivity to BET inhibition.

Chromatin and transcription regulators are critical to defining cell identity through shaping epigenetic and transcriptional landscapes, with their misregulation being closely linked to oncogenesis. Pharmacologically targeting these regulators, particularly the transcription-activating BET proteins, has emerged as a promising approach in cancer therapy, yet intrinsic or acquired resistance frequently occurs, with poorly understood mechanisms. Here, using genome-wide CRISPR screens, we find that BET inhibitor efficacy in mediating transcriptional silencing and growth inhibition depends on the auxiliary/arm/tail module of the Integrator-PP2A complex (INTAC), a global regulator of RNA polymerase II pause-release dynamics.

From marine debris to a valuable medical resource: A review on biology, chemistry, ethnopharmacology, bioactivity and application in biomedical materials of cuttlebone.

Ethnopharmacological Relevance: Cuttlebone (CB), also known as SEPIAE ENDOCONCHA, is the inner shell of cuttlefish and has been employed in traditional medicine in numerous countries since antiquity. Despite its significant medicinal value, CB is often underestimated and discarded on the beach as debris in some countries, which considerably impacts the environment and economy.

The Aim Of The Review: This study aims to elucidate the value of CB, particularly in the context of its medicinal properties, to promote its rational utilization.

A Space Telescope Scheduling Approach Combining Observation Priority Coding with Problem Decomposition Strategies.

With the increasing number of space debris, the demand for telescopes to observe space debris is also constantly increasing. The telescope observation scheduling problem requires algorithms to schedule telescopes to maximize observation value within the visible time constraints of space debris, especially when dealing with large-scale problems. This paper proposes a practical heuristic algorithm to solve the telescope observation of space debris scheduling problem.

Changes in Fibrinogen and D-Dimer During Complicated and Uncomplicated Pregnancy.

Introduction: The increase in fibrinogen levels is vital for the formation of a prothrombotic state during gestation to counter-bleeding challenges at delivery. However, pregnancy complications characterized by systemic inflammatory response syndrome may consume fibrinogen, resulting in elevated D-dimer levels.

Methods: Our study is based on a total of 16 768 pregnant women who delivered between December 1, 2013, and December 1, 2018, to study fibrinogen and D-dimer changes during gestation under normal and multiples of pathogenic states.

Polymer Based on Asymmetrically Halogenated Benzotriazole Enables High Performance Organic Solar Cells Prepared in Nonhalogenated Solvent.

Halogenation on the A unit of the D-π-A-type polymer donor has been proven as an effective strategy to improve the performance of organic solar cells (OSCs). Compared with fluorination, chlorination usually increases the open-circuit voltage because of the downward shift of energy levels, but decreases the charge transport ability due to the large steric hindrance of the chlorine atom. We reported herein a method to balance the energy loss and charge transport through asymmetric halogenation on the benzotriazole (BTA) unit of the polymer.

Flexible Microfluidic Strain Sensor Made with Poly(3,4-ethylenedioxythiophene):polystyrenesulfonate-MXene-Au Nanocomposites for Monitoring Physiological Signals.

Flexible strain sensors have been widely used in wearable electronics. However, the fabrication of flexible strain sensors with a large strain detection range, high sensitivity, and negligible hysteresis remains a formidable challenge, even after enormous advancements in the field. Herein, a flexible microfluidic strain sensor was fabricated by filling poly(3,4-ethylenedioxythiophene):polystyrenesulfonate-MXene-gold (PEDOT:PSS-MXene-Au) nanocomposites into microchannels in an elastic matrix.
