Inherent asymmetry of Rpd3S coordinates its nucleosome engagement and association with elongating RNA polymerase II.

The Rpd3S histone deacetylase complex has a crucial role in genomic integrity by deacetylating transcribed nucleosomes following RNA polymerase (Pol) II passage. Cryo-EM studies highlight the importance of asymmetrical Rco1-Eaf3 dimers in nucleosome binding, yet the interaction dynamics with nucleosomal substrates alongside elongating Pol II are poorly understood. Here we demonstrate the essential function of the Rco1 N-terminal intrinsically disordered region (IDR) in modulating Pol II association, in which K/R mutations within the Rco1 IDR impair interaction of Rpd3S with the C-terminal domain (CTD) of Rpb1, without affecting nucleosome recognition or complex integrity.

Introduction: The rate of sexual and gender minority (SGM) orthopaedic surgeons is far less than in other specialties, and the field has, in part, had significant difficulty attracting SGM applicants. To provide a more welcoming environment, identifying where applicants experience discrimination along medical training must be of paramount concern. Our objective was to understand the challenges faced by SGM medical students applying into orthopaedic surgery.

Article Synopsis
- Sepsis is a severe condition caused by an uncontrolled immune reaction to infections, often involving harmful bacteria like E. coli, and currently lacks effective treatments.
- Researchers developed E. coli wall-derived carbon dots (E-CDs) that can reduce inflammation and improve survival rates in septic mice by binding to immune receptors and preventing excessive immune responses.
- E-CDs also show promise in other models, reducing inflammation and oxidative stress, suggesting they could be a new therapeutic approach for treating sepsis by utilizing pathogen-derived materials.
Emotion Recognition Based on a EEG-fNIRS Hybrid Brain Network in the Source Space.

College of Electronic Information Engineering, Taiyuan University of Technology, Taiyuan 030600, China.
: Studies have shown that emotion recognition based on electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS) multimodal physiological signals exhibits superior performance compared to that of unimodal approaches. Nonetheless, there remains a paucity of in-depth investigations analyzing the inherent relationship between EEG and fNIRS and constructing brain networks to improve the performance of emotion recognition. : In this study, we introduce an innovative method to construct hybrid brain networks in the source space based on simultaneous EEG-fNIRS signals for emotion recognition.
