Method comparison and clinical classification agreement between Freelite and N-Latex serum-free light chain assays for clinical laboratory implementation

In 33 paired residual sera, Freelite produced significantly higher free-kappa values than N-Latex, while lambda did not differ significantly. Correlations were strong (rho 0.897 and 0.951), but Passing-Bablok analysis showed proportional kappa bias and Bland-Altman limits widened at extreme concentrations. Using assay-specific reference intervals, kappa/lambda classification agreed in 30 of 33 samples (91%; kappa 0.79). Numerical results are therefore not directly interchangeable.

Of Biomedicine and Barami: Melioidosis and the Politics of Visibility in Global Health

This medical-anthropology article examines how melioidosis moved from obscurity to becoming a visible object of evidence in global health. Focusing on Thai research and policy spaces, it argues that scientific knowledge is produced alongside barami, a culturally specific form of social capital. These relationships raise the visibility of researchers, the disease and its research sites at national and international levels.

Proof-of-concept development of a cost-effective PACE-based assay for CYP2C19 genotyping

A PCR Allelic Competitive Extension assay for CYP2C19*2, *3 and *17 was tested on 30 DNA samples against TaqMan. Concordance was 100%, with clear genotype clusters. Genotypes were *1/*1 53.3%, *1/*2 30.0%, *1/*3 10.0% and *2/*2 6.7%; *17 was absent. Reagent cost was reported as USD 4.34 or THB 135 per sample. This is encouraging proof of concept, not yet broad clinical validation.

Using Camera Trapping to Assess the Status of the Mammalian Community in the Mafou Fully Protected Area, Upper Niger National Park (Guinea)

During the January-May 2025 dry season, 53 cameras sampled the Mafou Fully Protected Area in Guinea for 4,239 camera-days. They yielded 10,334 usable files and 2,634 independent detections, documenting 30 taxa from 15 families and five orders, including six species of conservation concern. The assemblage included prey, mesopredators and apex predators, despite a notable human-activity index.

Artificial Intelligence-Based Evaluation of Brain–Tactile Interaction Using Electroencephalographic Signals and a Smart Haptic Glove

Participants interacted with a bottle, cube and sphere under natural-touch and vibrotactile-glove conditions while eight-channel EEG was recorded. A model trained on natural touch and tested on glove trials achieved rounded cross-condition accuracies of 83%, 78% and 68% for the three objects. Some object-related EEG structure transferred across conditions, but the authors explicitly caution that this does not demonstrate physiological equivalence.

Enhancing Marigold Seed Quality During Storage Through Fungicide Pelleting and Suppression of Pythium sp. at the Seedling Stage

A four-replicate completely randomized experiment evaluated fungicides for marigold seed pelleting. Mancozeb at 0.4 g active ingredient and fosetyl-aluminium at 0.1 g were selected as suitable treatments. Mancozeb at 0.4 g improved germination, vigor and seedling growth, and maintained laboratory germination and greenhouse viability after two months under controlled and ambient storage while suppressing Pythium.

Comparing Robust Image Retrieval and Waste Classification Using Deep Learning and Geometric Transformations

Using a custom dataset of 1,000 images in 10 waste classes, the study compared three ResNet backbones, three classifier heads and three losses. ResNet50 with a DenseNet201-based head and ArcFace achieved 98.4% accuracy, 98.3% F1 and 98.1% retrieval mAP, remaining stable under rotation and scaling. ResNet34 with a fully connected head and ArcFace offered a lighter performance-complexity trade-off.

Determinants of Oral Health System Effectiveness for Preschool Children in Decentralized Child Development Centres: A Cross-Sectional Study in Northeastern Thailand

A cross-sectional study in Ubon Ratchathani surveyed 270 stakeholders and used dental records from 498 preschool children. Perceived system effectiveness was high (mean 4.01/5), yet caries prevalence was 57.83%. Service-delivery processes and home visits were significant predictors, but the model explained only 11.1% of variance and the system score was partly perception-based.

First Report of Fusarium oxysporum f. sp. cubense tropical race 4 (VCG 01213/16) causing Fusarium wilt on banana in Bangladesh

After wilt symptoms appeared in five Bangladeshi districts in early 2025, 21 pseudostem samples were cultured. Fusarium oxysporum f. sp. cubense tropical race 4 was confirmed by morphology, specific PCR and vegetative compatibility group 01213/16. Nineteen isolates caused typical disease within four weeks in Cavendish plantlets, controls remained healthy, and the pathogen was reisolated to complete Koch’s postulates.

A thermodynamically consistent strain-gradient model for functionally graded nanobeams with composite damage mechanics on elastic substrate medium

This theoretical study develops a thermodynamically consistent strain-gradient model for functionally graded Euler-Bernoulli nanobeams on a Winkler foundation. Damage is assigned to the ceramic phase while the metal remains intact. Voigt, Reuss and a proposed effective-property formulation are compared in analytical static-bending solutions. Damage lowers stiffness and increases deflection, while greater ceramic content and foundation stiffness increase rigidity; the proposed response remains between the Voigt and Reuss bounds.

Synthesis, structural, optical, and electrical properties of L-methioninium nitrate for optoelectronic applications

Single crystals of L-methioninium nitrate were grown by slow evaporation from a 1:1 L-methionine/nitric-acid mixture. X-ray diffraction identified a monoclinic structure with low lattice strain. FTIR supported molecular assignment, photoluminescence showed a broad 330-550 nm emission, and impedance analysis indicated bulk-dominated conduction, non-Debye relaxation and low high-frequency dielectric loss. Second-harmonic generation was also assessed by the Kurtz-Perry powder method.

Topical mosquito repellency of a Litsea cubeba essential oil spray against Aedes aegypti, Anopheles dirus, and Culex quinquefasciatus

MosShield, a ready-to-use spray containing 6% Litsea cubeba essential oil, underwent formulation quality checks and a skin-patch test in 48 healthy volunteers, with no visible reaction through 96 hours. WHO arm-in-cage tests produced median complete protection times of 225 minutes against Culex quinquefasciatus and 120 minutes against both Aedes aegypti and Anopheles dirus. These are laboratory, not field-effectiveness, results.
