Split Nitrogen Application Improves Yield and Partial Factor Productivity of Nitrogen in Rice (cv. RD49) Under Low-Fertility Sandy Loam Soil

Nitrogen (N) management is critical for improving rice productivity, but increasing N inputs may reduce N-use productivity when grain production does not increase proportionally. This study evaluated the effects of urea rate and application method on grain weight and partial fact...

Outcomes of radioactive iodine therapy with fixed-activity regimen in pediatric Graves' disease.

OBJECTIVE: To evaluate the success rates of radioactive iodine therapy (RAIT) with fixed activity of 10mCi and 15mCi in pediatric patients with Graves' disease (GD). SUBJECTS AND METHODS: dose of RAIT by fixed activity regimen, either 10mCi or 15mCi. The rates of successful thera...

AI-assisted and human-driven food packaging design: Consumer perceptions of creativity and cultural communication in a GI rambutan beverage

As artificial intelligence (AI) becomes increasingly embedded in food-related design practices, its role in shaping culturally meaningful packaging remains insufficiently understood. This study explores differences in perceived creativity and communicative effectiveness between h...

Diagnostic performance of Baermann technique, urine-ELISA, stool-PCR and Strongyloides IgG4 rapid test for diagnosis of strongyloidiasis: a study protocol

Strongyloidiasis is caused by a parasitic worm, primarily Strongyloides stercoralis . In rural settings of Côte d’Ivoire, parasitological surveys have revealed that the prevalence of S. stercoralis infection can reach up to 50%. The World Health Organization has included S. sterc...

Nanoplate Digital PCR for Identification of α0-Thalassemia (SEA Deletion): Carrier Screening and Possible Application to Prenatal Diagnosis

The Southeast Asian deletion (--SEA), the most prevalent α0-thalassemia mutation in Southeast Asia, is a major target of regional thalassemia prevention programs. Coinheritance of α0-thalassemia with other hemoglobinopathies, particularly hemoglobin E (Hb E), complicates routine...

Are dispersed rice planting dates linked to higher provincial yields? Evidence from Northeast Thailand

Abstract Planting date is an important determinant of wet-season rice performance in monsoon Asia. However, it is influenced not only by rainfall but also by irrigation access, drainage conditions, and field operability. This study quantified how the spatial distribution and disp...

Metabolic and Inflammatory Risk Stratification in Resected Cholangiocarcinoma: A Retrospective Exploratory Analysis

Background: Cholangiocarcinoma (CCA) frequently recurs after curative-intent resection. Metabolic alterations and systemic inflammation may contribute to aggressive disease, but their combined prognostic relevance remains unclear. Methods: We retrospectively reanalyzed 88 patient...

Musculoskeletal pain and associated occupational factors among emergency personnel in Nakhon Pathom Province Thailand

Abstract Musculoskeletal pain is a common occupational health problem among emergency medical service personnel due to the physically demanding nature of their work. This study aimed to determine the prevalence of musculoskeletal pain and identify associated factors among emergen...

Application of serum MUC4/MUC1 ratio for diagnosis of meningioma and glioblastoma

Background Meningiomas (MGs) are the most common primary brain tumors, arising from arachnoid cap cells within the meninges. There is currently no validated, clinically used serum marker for brain tumors; diagnosis still relies on imaging and histopathology/molecular testing of r...

The sustainability paradox in urban food tourism: dissonance, control, and moral disengagement among Gen Z

Urban food tourism intersects with sustainability agendas, yet informal street-food ecosystems often lack visible environmental practices, creating governance and behavior-formation challenges for pro-sustainability cohorts such as Generation Z (Gen Z). This study examines how un...

Synergistic effects of sustainable SiO₂ nanoparticle reinforcement and Sr modification on the microstructure, mechanical performance, and tribological behavior of ADC12 hybrid composites

This study developed a sustainable ADC12 hybrid composite reinforced with SiO₂ nanoparticles and modified with Sr to improve its mechanical and tribological performance. The SiO₂ reinforcement, derived from silica-rich agricultural and industrial waste, provides an environmentall...

Discovery of Bis-ThioureaDerivatives as Human DNATopoisomerase IIα Inhibitors with Potent Anticancer Effects

Abstract DNA topoisomerase IIα (Topo IIα) is essential for maintaining genomic stability during DNA replication and mitosis and is highly expressed in cancer cells, making it a promising target for anticancer therapy. In this study, bis-thiourea derivatives were investigated for...

Sustainable Synthesisof Diamide Solvents from SuccinicAnhydride under Microwave Conditions for the Production of Graphenevia Liquid-Phase Exfoliation

Abstract Liquid-phase exfoliation (LPE) is a viable method for the large-scale production of two-dimensional (2D) graphene; however, toxic solvents must be replaced. The microwave synthesis of sustainable succindiamide solvents, namely N,N′-diethyl-N,N′-dibutylsuccindiamide (EBSA...

Effects of Molasses-Based Liquid Feeds Containing Conventional Urea or Commercial Fat-Coated Urea Product on In Vitro Rumen Fermentation, Gas Kinetics, and Substrate Degradability

This study evaluated molasses-based liquid feeds containing conventional urea or a commercial fat-coated urea product marketed as slow-release urea (SRU). The effects on in vitro gas-production kinetics, rumen fermentation, and substrate degradability were examined. Treatments fo...

Effects of Fermented Fish Residue-Derived Liquid Organic Fertilizer on Soil Chemical Properties, Nutrient Use Efficiency, and Lettuce Growth in Tropical Sandy Soil

Fermented fish residue (FFR) is a byproduct generated from the fermented fish industry and presents a significant opportunity for waste valorization into liquid organic fertilizer (OF). This study aimed to determine the chemical properties of FFR and its derived OF, along with th...
