This study analyzed soil HM samples from 53 different land use types in Jiaozuo City, Henan Province, China. Pollution sources were identified using Absolute Principal Component Score (APCS), with 8 anthropogenic factors, 9 natural factors, and 4 soil physicochemical properties mapped using Geographic Information System (GIS) kernel density estimation.

Quantitative Assessment of the Effect of Chronic Kidney Disease on Plasma P-Tau217 Concentrations.

Background And Objectives: Chronic kidney disease (CKD) is known to be associated with increased plasma phosphorylated tau217 (p-tau217) concentrations, potentially confounding the utility of plasma p-tau217 measurements as a marker of amyloid pathology in individuals with suspected Alzheimer disease (AD). In this study, we quantitatively investigate the relationship of plasma p-tau217 concentrations vs estimated glomerular filtration rate (eGFR) in individuals with CKD with and without amyloid pathology.

Methods: This was a retrospective examination of data from 2 observational cohorts from either the Mayo Clinic Study of Aging or the Alzheimer's Disease Research Center cohorts.

Clinical Manifestations and Treatment Responses in Pediatric Neurofascin 155-IgG4 Autoimmune Nodopathy.

Walking or hanging: the role of habitat use for body shape evolution in lacertid lizards.

Differences in habitat use impose ecological constraints which in turn lead to functional and morphological differences through adaptation. In fact, a convergent evolutionary pattern is evident when species exhibit similar responses to similar environments. In this study we examine how habitat use influences the evolution of body shape in lizards from the family Lacertidae.

Sudden Cardiac Arrest Associated with Hemodialysis: A Community-Based Study.

Effects of HMG CoA reductase (HMGCR) deficiency on skeletal muscle development.

Pathogenic variants in HMGCR were recently linked to a limb-girdle muscular dystrophy (LGMD) phenotype. The protein product HMG CoA reductase (HMGCR) catalyzes a key component of the cholesterol synthesis pathway. The two other muscle diseases associated with HMGCR, statin-associated myopathy (SAM) and autoimmune anti-HMGCR myopathy, are not inherited in a Mendelian pattern.

Design and validation of cell-based potency assays for frataxin supplementation treatments.

Friedreich's ataxia (FRDA) is a multisystem, autosomal recessive disorder caused by mutations in the frataxin () gene. As FRDA is considered an FXN deficiency disorder, numerous therapeutic approaches in development or clinical trials aim to supplement FXN or restore endogenous expression. These include gene therapy, protein supplementation, genome editing or upregulation of transcription.

Is Topical Tranexamic Acid Effective in Reducing Hematoma and Seroma in Breast Surgery? A Systematic Review and Meta-analysis.

Background: Postoperative fluid-related complications, such as hematoma and seroma formation, are common concerns in breast surgery, adversely affecting surgical outcomes and patient recovery. Topical tranexamic acid (TXA) has emerged as a promising intervention to minimize bleeding while reducing systemic adverse effects linked to intravenous administration. However, evidence on the efficacy of topical TXA in breast surgery remains sparse.

Rapid (≤25 °C) cycloisomerization of anhydride-tethered triynes to benzynes - origin of a remarkable anhydride linker-induced rate enhancement.

The hexadehydro-Diels-Alder (HDDA) reaction is a cycloisomerization between a conjugated diyne and a tethered diynophile that generates -benzyne derivatives. Considerable fundamental understanding of aryne reactivity has resulted from this body of research. The multi-yne cycloisomerization substrate is typically pre-formed and the (rate-limiting) closure of this diyne/diynophile pair to produce the isomeric benzyne generally requires thermal input, often requiring reaction temperatures of >100 °C and times of 16-48 h to achieve near-full conversion.

LPMO-Catalyzed Oxidation of Cellulosic Fibers with Controlled Addition of a Reductant and HO.

Cellulose-derived biomaterials offer a sustainable and versatile platform for various applications. Enzymatic engineering of these fibers, particularly using lytic polysaccharide monooxygenases (LPMOs), shows promise due to the ability to introduce functional groups onto cellulose surfaces, potentially enabling further functionalization. However, harnessing LPMOs for fiber engineering remains challenging, partly because controlling the enzymatic reaction is difficult and partly because limited information is available about how LPMOs modify the fibers.

Serial intrauterine transfusion for severe fetal anemia due to anti-M alloimmunization.

Centering historically minoritized populations to design effective messages about an evidence-based policy to advance social equity.

Researchers have raised concerns that messages describing racial disparities in social outcomes can reduce or polarize support for public policies to address inequality. We questioned this assumption by testing the impact of carefully crafted messages about child tax credit (CTC) expansion. We conducted two randomized message trials, study 1 using Prolific's nonprobability panel ( = 1,402) and study 2 using SSRS's Opinion Panel, a web-based probability sample of US adults ( = 4,483).

Complementary and Integrative Health Use in Binge Eating Disorder: A Cross-Sectional Mixed-Methods Study of Binge Eating Disorder Experts' Perspectives.

Introduction: Binge Eating Disorder (BED) has high lifetime prevalence rates, low treatment success rates, and high rates of treatment dissatisfaction, early discontinuation of care, and recurrence. Complementary and integrative health (CIH) interventions (non-mainstream practices used with conventional approaches for whole-person treatment) hold potential to overcome many treatment barriers and improve BED treatment outcomes. Some CIH interventions have empirical support for use in eating disorders.

Local Structure Regulation for Oxygen Redox and Structure Stability of P2-Type Cathodes.

The local structure plays a crucial role in oxygen redox reactions, which boosts the capacity of layered oxide cathodes for sodium-ion batteries. While studies on local structural ordering have primarily focused on the intra-layer ordering, there has been limited research on the inter-layer stacking for the layered cathode materials for sodium-ion batteries. In this work, the impact of the intra-layer and inter-layer local structural regulation on anionic kinetics and the structure stability are explored through experimental analysis and theoretical calculations.
