Seroprevalence of Toxoplasma gondii among pregnant women seeking antenatal care in Ho Municipality of the Volta Region of Ghana

Toxoplasmosis, caused by Toxoplasma gondii , is a globally prevalent zoonotic infection with significant maternal–fetal health consequences. In Ghana, regional studies have reported high seroprevalence among pregnant women, but data from the Volta Region remain limited. A cross-s...

Coniferaldehyde Reverses PGK1–3-Phosphoglycerate–L-Serine Metabolic Reprogramming in Hindlimb Ischemia

Background/Objectives: Ischemic skeletal muscle undergoes metabolic remodeling that may influence vascular repair. We investigated whether coniferaldehyde (CA) regulates a phosphoglycerate kinase 1 (PGK1)–3-phosphoglycerate (3PG)–L-serine axis in mouse hindlimb ischemia (HLI). Me...

Dual-Encoder Network Optimization for Binary Semantic Segmentation of Focal Liver Lesions (FLLs)

Automated binary semantic segmentation of focal liver lesions (FLLs) in multi-phasic computed tomography (CT) scans is important for knowledge extraction of hepatic malignancy, staging disease, and planning treatment. However, standard models struggle due to extreme class imbalan...

HIV transmission behaviors, detectable HIV-RNA and curable STI prevalence among Ugandan men with HIV with reproductive goals, with and without infertility experiences

Many men with HIV (MWH) want children. MWH with unmet reproductive goals may prioritize conception over preventing HIV/STI transmission. Therefore, we evaluated whether MWH with unmet versus met reproductive goals were more likely to have detectable HIV-RNA or STIs, and explored...

Bonded Agents: What a Surety Would Have to Establish Before Standing Behind an Autonomous Role.

An autonomous role can fail in two ways at once: it can breach an undertaking, and it can compromise the evidence needed to establish the breach. Where the deploying organization controls the execution record, the counterparty may depend on that organization both to perform and t...

Buckling load parameter analysis of rectangular plate with full and partial stiffeners under uniaxial and biaxial loading conditions

Finite element analysis is used to examine the buckling properties of rectangular plates with full and partial longitudinal and transverse stiffeners under in-plane uniaxial edge loadings. Various edge-loading scenarios have been examined, and whenever feasible, comparisons with...

Dishing Out Public Goods: School Food Workers and the Struggle to (Re)value Reproductive Labor

Government-funded school food programs in the USA have recently expanded access to free meals and incorporated more scratch cooking with local ingredients, but school food workers (SFWs) have seen little-to-no improvement in their working conditions. Using focus group data from t...

Major-Earthquake Recurrence Patterns on Active Faults in Yunnan Province, China

ABSTRACT Earthquake forecasting along active faults is important for reducing future seismic losses, especially in active zones such as Yunnan Province. However, the major earthquake recurrence patterns of faults in Yunnan remain understudied, and the time-dependent probabilities...

The paradox of violent sanctuary: rethinking the concept of sanctuary in protracted refugee camp contexts

Refugee camps have been depicted as spaces that adversely affect refugees by, among other things, exposing them to psychosocial problems, violence, exploitation, and material deprivation. In Kakuma, the prevalence of violence inside and around the camp, which involves serious inj...

Adrenal Infections: An Underrecognized Cause of Primary Adrenal Insufficiency

INTRODUCTION: Adrenal infections are an underrecognized but clinically significant cause of primary adrenal insufficiency (PAI). OBJECTIVES: This review proposes a diagnostic algorithm for the evaluation of suspected cases. RESULTS: The most common causative pathogens are Mycobac...

Evaluating the Marginal Seal of Bioactive Restorative Material and Two Bulk-fill Composites in Class II Restorations: An In Vitro Study

Background: Marginal microleakage remains a major concern in posterior composite restorations, contributing to recurrent caries, postoperative sensitivity, pulpal irritation, and eventual restoration failure.Polymerization shrinkage stress and poor marginal adaptation are signifi...

Dynamic event-triggered adaptive cooperative control for robotic manipulator with output constraints and model uncertainties

This paper introduces an adaptive fuzzy-based dynamic event-triggered adaptive cooperative control to address the challenge of achieving high-performance control for robotic manipulators under model uncertainties and output constraints. This strategy designs a signal-processing-b...

E8 Root Vector Quaternion Lattice Defines Conscious State Manifold Topology — E8 Intelligence Research

The 240 E8 root vectors, when partitioned through their quaternion components (scalar + 3 imaginary axes) and cross-referenced with the 132Hz phase boundary, generate a 4-dimensional conscious state manifold where each point corresponds to a unique quaternion-valued coherence ten...

Systematic review and network meta-analysis of performance of the Sapporo criteria, the Revised Sapporo criteria, and the 2023 ACR/EULAR APS classification criteria for patients with antiphospholipid syndrome: A protocol

Background Antiphospholipid syndrome is an autoimmune disorder characterized by recurrent thrombotic events and/or adverse pregnancy outcomes. Although three classification criteria—the 1999 Sapporo criteria, the Revised Sapporo criteria, and the 2023 ACR/EULAR antiphospholipid s...

Dynamic user interest modeling and prediction integrating query box embedding with graph neural networks

User interests are multi-peaked, vaguely bounded, and prone to temporal drift, yet most recommendation models still encode them as single points in a latent space, discarding coverage and uncertainty alike. This paper represents interest as a region rather than a location, and le...
