Hormone Regulation of Corticotropin-Releasing Factor Receptor 1 in the Female Mouse Brain.

Introduction: Corticotropin-releasing factor receptor 1 (CRFR1) is a key regulator of neuroendocrine and behavioral stress responses. Previous studies have demonstrated that CRFR1 in certain hypothalamic and preoptic brain areas is modified by chronic stress and during the postpartum period in female mice, although the potential hormonal contributors to these changes are unknown.

Methods: This study focused on determining the contributions of hormones associated with stress and the maternal period (glucocorticoids, prolactin, estradiol/progesterone) on CRFR1 levels using a CRFR1-GFP reporter mouse line and immunohistochemistry.

Alkanes C-C C-H Bond Activation via a Barrierless Potential Energy Path: Trifluoromethyl Carbenes Enhance Primary C-H Bond Functionalization.

In this mixed computational and experimental study, we report a catalytic system for alkane C-C functionalization in which the responsible step for C-H bond activation shows no barrier in the potential energy path. DFT modeling of three silver-based catalysts and four diazo compounds led to the conclusion that the TpAg═C(H)CF (Tp = fluorinated trispyrazolylborate ligand) carbene intermediates interact with methane without a barrier in the potential energy surface, a prediction validated by experimentation using N═C(H)CF as the carbene source. The array of alkanes from propane to -hexane led to the preferential functionalization of the primary sites with unprecedented values of selectivity for an acceptor diazo compound.

Development and validation of the post-CAR prognostic index for large B-cell lymphoma patients after CAR-T progression in third or later line treatment.

Chimeric antigen receptor (CAR) T-cell therapy fails to achieve durable responses in over 60% of relapsed/refractory (R/R) large B-cell lymphoma (LBCL) patients in the third or later line setting. After CAR-T failure, survival outcomes are heterogeneous and a prognostic model in this patient population is lacking. A training cohort of 216 patients with progressive disease (PD) after CAR-T from 12 Spanish centers was used to develop the Post-CAR Prognostic Index (PC-PI); primary endpoint was overall survival (OS) from CAR-T progression.

Severity and organ distribution of graft-versus-host disease with post-transplant cyclophosphamide versus calcineurin inhibitor plus methotrexate/mycophenolate mofetil or sirolimus in allogenic HLA-matched or single-allele mismatched stem cell transplantation.

Objective: This retrospective single center study aims to describe changes in the severity and organ-specific distribution of GvHD, by comparing the outcomes of 3 distinct GvHD prophylaxis approaches.

Methods: Between January 2012 and June 2022, 226 patients underwent allogeneic hematopoietic stem cell transplantation from HLA-matched or 1-allele mismatched related or unrelated donors. Fifty-eight (26%) received prophylaxis with calcineurin inhibitor in combination with mycophenolate mofetil or a short course of methotrexate (Cohort-1), 87 (38%) tacrolimus plus sirolimus (Cohort-2), and 81 (36%) post-transplant cyclophosphamide (PTCy) plus tacrolimus (Cohort-3).

Polyaniline-Coated NaV(PO)F Cathode Enables Fast Sodium Ion Diffusion and Structural Stability in Rechargeable Batteries.

NaV(PO)F (NVPF), a typical sodium superionic conductor (NASICON) type structure, has attracted much interest as a potential positive electrode in sodium-ion battery. However, the inherently poor electronic conductivity of phosphates compromises the electrochemical properties of this material. Here, we develop a general strategy to improve the electrochemical performance by preparing a new composite material "polyaniline (PANI)@NVPF" using a Pickering emulsion method.

Anti-CD19 CAR-T Cell Therapy in Elderly Patients: Multicentric Real-World Experience from GETH-TC/GELTAMO.

Chimeric antigen receptor (CAR)-T cell therapy is approved for the treatment of relapsed/refractory (R/R) large B cell lymphoma (LBCL). However, elderly patients might not be candidates for this therapy due to its toxicity, and criteria for candidate selection are lacking. Our aim was to analyze efficacy and toxicity results of CAR-T cell therapy in the population of patients 70 years and older as compared to those obtained in younger patients in the real-world setting.

PBAT is biodegradable but what about the toxicity of its biodegradation products?

Context: Poly(butylene adipate-co-terephthalate) (PBAT) is a biodegradable plastic. It was introduced to the plastics market in 1998 and since then has been widely used around the world. The main idea of this research is to perform quantum chemical calculations to study the potential toxicity of PBAT and its degradation products.

Chronic obstructive pulmonary disease related to wood smoke and impact of the combined exposure to tobacco.

Background: Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 highlights the need to explore aetiotypes of chronic obstructive pulmonary disease (COPD) beyond the tobacco-smoking COPD. Exposure to wood smoke (WS) is a risk factor for COPD in women, but the effect of the combined exposure to tobacco smoke (TS) in the general population and among COPD patients, and the characteristics of WS-COPD are unclear.

Method: This was an analysis of data from PREPOCOL (Prevalence of COPD in Five Colombian Cities Situated at Low, Medium, and High Altitude), a random cross-sectional population-based study ( = 5,539) focusing on the effect of combined WS and TS exposure and WS-COPD characterisation.

Patient-specific analysis of bicuspid aortic valve hemodynamics using a fully coupled fluid-structure interaction model.

Bicuspid aortic valve (BAV), the most common congenital heart disease, is prone to develop significant valvular dysfunction and aortic wall abnormalities such as ascending aortic aneurysm. Growing evidence has suggested that abnormal BAV hemodynamics could contribute to disease progression. In order to investigate BAV hemodynamics, we performed 3D patient-specific fluid-structure interaction (FSI) simulations with fully coupled blood flow dynamics and valve motion throughout the cardiac cycle.
