Neoadjuvant nivolumab and chemotherapy in early estrogen receptor-positive breast cancer: a randomized phase 3 trial.

Patients with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) primary breast cancer (BC) have low pathological complete response (pCR) rates with neoadjuvant chemotherapy. A subset of ER+/HER2- BC contains dense lymphocytic infiltration. We hypothesized that addition of an anti-programmed death 1 agent may increase pCR rates in this BC subtype.

Structural mechanism underlying PHO1;H1-mediated phosphate transport in Arabidopsis.

Arabidopsis PHOSPHATE 1 (AtPHO1) and its closest homologue AtPHO1;H1 are phosphate transporters that load phosphate into the xylem vessel for root-to-shoot translocation. AtPHO1 and AtPHO1;H1 are prototypical members of the unique SPX-EXS family, whose structural and molecular mechanisms remain elusive. In this study, we determined the cryogenic electron microscopy structure of AtPHO1;H1 binding with inorganic phosphate (Pi) and inositol hexakisphosphate in a closed conformation.

FGFR antagonists restore defective mandibular bone repair in a mouse model of osteochondrodysplasia.

Gain-of-function mutations in fibroblast growth factor receptor (FGFR) genes lead to chondrodysplasia and craniosynostoses. FGFR signaling has a key role in the formation and repair of the craniofacial skeleton. Here, we analyzed the impact of Fgfr2- and Fgfr3-activating mutations on mandibular bone formation and endochondral bone repair after non-stabilized mandibular fractures in mouse models of Crouzon syndrome (Crz) and hypochondroplasia (Hch).

Broad geographic dispersal is not a diversification driver for Emberizoidea.

The movement of species to new geographical areas has been proposed to be crucial for speciation. As such, dispersal has been regarded as a likely explanation for the variation in species richness among clades. The Emberizoidea are a highly diverse Oscine bird clade native to the New World that has been characterized for their ubiquitous distribution both ecologically and geographically, making this group ideal to test how biogeographical dispersal could promote speciation.

Manipulating Crystal Packing and Self-Assembly by π-Extended and Isomeric Fused Strategies in Thiophene Ring-Terminated Polycyclic Aromatic Hydrocarbons.

Two series of polycyclic aromatic hydrocarbon isomers ( and , and and ) were designed and synthesized by isomerically fusing phenanthrene with thiophene and thieno[3,2-]thiophene, respectively. All of the new target molecules were confirmed by single-crystal X-ray analysis, and it was found that the solid-state packing can be effectively modulated through a combination of π-extended and isomeric fused strategies. Meanwhile, compared with thiophene ring-terminated isomers and , both having a V-shaped geometry and showing no obvious self-assembly behavior, π-extended unit thieno[3,2-]thiophene-terminated isomer displays a V-shaped structure with moderate self-assembly properties and isomer exhibits a C-shaped configuration with further enhanced self-assembly properties.

Deep Learning-Enabled Assessment of Right Ventricular Function Improves Prognostication After Transcatheter Edge-to-Edge Repair for Mitral Regurgitation.

Background: Right ventricular (RV) function has a well-established prognostic role in patients with severe mitral regurgitation (MR) undergoing transcatheter edge-to-edge repair (TEER) and is typically assessed using echocardiography-measured tricuspid annular plane systolic excursion. Recently, a deep learning model has been proposed that accurately predicts RV ejection fraction (RVEF) from 2-dimensional echocardiographic videos, with similar diagnostic accuracy as 3-dimensional imaging. This study aimed to evaluate the prognostic value of the deep learning-predicted RVEF values in patients with severe MR undergoing TEER.

Quantum Dot Erythropoietin Bioconjugates Enhance EPO-Receptor Clustering on Transfected Human Embryonic Kidney Cells.

Erythropoietin (EPO)-induced cellular signaling through the EPO receptor (EPOR) is a fundamental pathway for the modulation of cellular behavior and activity. In our previous work, we showed in primary human astrocytes that the multivalent display of EPO on the surface of semiconductor quantum dots (QDs) mediates augmented JAK/STAT signaling, a concomitant 1.8-fold increase in the expression of aquaporin-4 (AQPN-4) channel proteins, and a 2-fold increase in the AQPN-4-mediated water transport activity.
