Systemic Sirolimus Therapy Is Associated With Reduced Intervention Frequency in Pulmonary Vein Stenosis.

Background: Early clinical outcomes data for adjunctive systemic sirolimus therapy (SST) for moderate to severe pediatric pulmonary vein stenosis (PVS) are promising but limited.

Objectives: The authors aimed to characterize a cohort of patients treated with SST to determine if SST was associated with a reduction in frequency of PVS interventions.

Methods: Medical records of 45 patients with PVS treated with SST for ≥1 month from 2015 to 2022 were retrospectively reviewed.

How to monitor and discriminate the causes of lower limb swelling during home-based rehabilitation after total knee arthroplasty? A delphi study.

Purpose: Swelling in the lower limbs after total knee arthroplasty (TKA) affects surgical outcomes. Prolonged swelling requires monitoring and remote management during home-based rehabilitation. Causes of swelling vary but, so far, no indicators are available to monitor and identify causes of lower limb swelling, making it difficult to implement targeted interventions.

Deficiency of Endothelial Impairs Pulmonary Vascular Angiogenesis and Predisposes Pulmonary Hypertension.

Background: Mechanosensitive Piezo1 channel plays a key role in pulmonary hypertension (PH). However, the role of Piezo2 in PH remains unclear.

Methods: Endothelial cell (EC)-specific knockout (, Tek-Cre; ) rats and primarily cultured pulmonary microvascular ECs were used to determine the role of Piezo2 in PH.

Integrative mapping of human CD8 T cells in inflammation and cancer.

CD8 T cells exhibit remarkable phenotypic diversity in inflammation and cancer. However, a comprehensive understanding of their clonal landscape and dynamics remains elusive. Here we introduce scAtlasVAE, a deep-learning-based model for the integration of large-scale single-cell RNA sequencing data and cross-atlas comparisons.

Up-Regulated Expression of Thioredoxin-Interacting Protein (TXNIP) in Mesenchymal Stem Cells Associated with Severe Aplastic Anemia in Children.

The pathogenic mechanisms of severe aplastic anemia (SAA) in children are not completely elucidated. The insufficiency of the bone marrow microenvironment, in which mesenchymal stem cells (MSCs) are an important element, can be a potential factor associated with hematopoietic impairment in SAA. In the present study, we compared bone marrow MSCs from five children with SAA and five controls.

Association between thyroid hormones and cognitive functioning in euthyroid elderly adults: a cross-sectional preliminary study from the NHANES 2011-2012 survey.

Objective: Changes in serum thyroid hormone levels may affect cognitive functioning in euthyroid individuals. This study used representative data from the National Health and Nutrition Examination Survey (NHANES) to comprehensively examine the association of thyroid hormones with different tests of cognitive functioning among US elderly people aged ≥60 years.

Methods: This study was a cross-sectional preliminary study with a total of 734 participants from the NHANES 2011-2012 survey.

One-Stage Orbital Decompression Combined With Intraoperative Muscle Relaxation for TAO: A Randomized Controlled Trial.

Purpose: To gauge the efficacy and safety of performing a one-stage endoscopic orbital decompression procedure combined with the intraoperative relaxed medial rectus muscle (MR) positioning technique as a means of treating esotropia associated with thyroid-associated ophthalmopathy (TAO).

Design: Prospective, single-blind, randomized controlled trial.

Setting: Eye Hospital of Wenzhou Medical University.

Non-serious adverse events in patients with ulcerative colitis receiving etrasimod: an analysis of the phase II OASIS and phase III ELEVATE UC 52 and ELEVATE UC 12 clinical trials.

Background: Etrasimod is an oral, once-daily (QD), selective sphingosine 1-phosphate (S1P) receptor modulator for the treatment of moderately to severely active ulcerative colitis (UC). It is known that non-serious treatment-emergent adverse events (TEAEs) may not lead to UC drug discontinuation but can affect treatment tolerability.

Objectives: This post hoc analysis evaluated the incidence of specific, common, non-serious TEAEs reported in the etrasimod UC clinical programme and the characteristics of affected patients.

ANK Deficiency-Mediated Cytosolic Citrate Accumulation Promotes Aortic Aneurysm.

Background: Disturbed metabolism and transport of citrate play significant roles in various pathologies. However, vascular citrate regulation and its potential role in aortic aneurysm (AA) development remain poorly understood.

Methods: Untargeted metabolomics by mass spectrometry was applied to identify upregulated metabolites of the tricarboxylic acid cycle in AA tissues of mice.

Exposure-lag response of surface net solar radiation on lung cancer incidence: a global time-series analysis.

Background: Recently, the impact of solar radiation (RAD) on diseases worldwide has garnered growing attention. However, the association between RAD and lung cancer remains largely unknow and no consensus has been reached. The aim of this study was to investigate the lag exposure-response of RAD on lung cancer and provide robust scientific evidence for updating prevention and treatment strategies of lung cancer.

Integrated Deep Learning Model for the Detection, Segmentation, and Morphologic Analysis of Intracranial Aneurysms Using CT Angiography.

Purpose To develop a deep learning model for the morphologic measurement of unruptured intracranial aneurysms (UIAs) based on CT angiography (CTA) data and validate its performance using a multicenter dataset. Materials and Methods In this retrospective study, patients with CTA examinations, including those with and without UIAs, in a tertiary referral hospital from February 2018 to February 2021 were included as the training dataset. Patients with UIAs who underwent CTA at multiple centers between April 2021 and December 2022 were included as the multicenter external testing set.

New insights into the improved contaminants removal in SBR by intermittently weak ultrasound.

The combination of intermittently weak ultrasound and sequencing batch reactor was thoroughly investigated to elucidate the relationship between enhanced contaminants removal and activated sludge characteristics, microbial composition, and regulation of differentially expressed genes (DEGs). At 12 °C, irradiation with an ultrasound intensity of 9.68 W/L, an irradiation time of 10 min, and an interval time of 24 h led to significant increases in COD, NH-N, and TP removals with the rates of 93.

Precise genetic control of ATOH1 enhances maturation of regenerated hair cells in the mature mouse utricle.

Vestibular hair cells are mechanoreceptors critical for detecting head position and motion. In mammals, hair cell loss causes vestibular dysfunction as spontaneous regeneration is nearly absent. Constitutive expression of exogenous ATOH1, a hair cell transcription factor, increases hair cell regeneration, however, these cells fail to fully mature.

Functional Analysis of BARD1 Missense Variants on Homology-Directed Repair in Ovarian and Breast Cancers.

Women with germline BRCA1 mutations face an increased risk of developing breast and ovarian cancers. BARD1 (BRCA1 associated RING domain 1) is an essential heterodimeric partner of BRCA1, and mutations in BARD1 are also associated with these cancers. While BARD1 mutations are recognized for their cancer susceptibility, the exact roles of numerous BARD1 missense mutations remain unclear.

Lactone-to-Lactam Editing Alters the Pharmacology of Bilobalide.

Precise transformations of natural products (NPs) can fine-tune their physicochemical properties while preserving inherently complex and evolutionarily optimized parent scaffolds. Here, we report an unprecedented lactone-to-lactam transformation on bilobalide, thus improving its stability and paving the way for biological exploration of previously inaccessible chemical space that is highly representative of the parent structure. This late-stage molecular editing of bilobalide enables facile access to a unique library of lactam analogues with altered pharmacology.
