Reproductive Health and Contraceptive Implants73IMPACT SIGNAL
Evidence of global relevance

Contraceptive implant discontinuation at one year in adults and adolescents: Implications for adolescent reproductive health services

A retrospective cohort of 2,014 etonogestrel or levonorgestrel implant initiators in 2016-2021 found one-year discontinuation at 3.83 per 100 person-years overall, 2.84 in adolescents and 4.16 in adults, with no significant difference. Sequential users had lower hazard (aHR 0.29), and abnormal bleeding was the leading reason. Single-centre findings should not diminish adolescent-specific services.

Evidence of global relevance

Identification and protein modelling analysis of a homozygous FUT1*01W.09 variant in a Thai patient with the para‐Bombay phenotype

A single Thai para-Bombay case was studied by serology, whole-exome/Sanger sequencing and protein modelling. Homozygous FUT1 c.658C>T (p.Arg220Cys; FUT1*01W.09) accompanied ABO*B.01 and a silent FUT2 variant. Modelling suggested impaired substrate interactions without global destabilisation. The result informs compatible transfusion, but mechanism is in silico and evidence comes from one patient.

Natural-Product Chemistry and EGFR Inhibition73IMPACT SIGNAL
Evidence of global relevance

Late-stage halogenation of Scortechinone D via NaX oxidation and inhibitory activity against EGFR tyrosine kinase

Thai chemists used Oxone and sodium halides for late-stage halogenation of scortechinone D, yielding three new derivatives characterised by NMR/HRMS and X-ray for the iodo compound. Compound 2 inhibited EGFR tyrosine kinase by 63.5% at 10 μM but also suppressed normal WI-38 cell growth by 58.8% at the same concentration, indicating poor selectivity and no drug-ready lead.

Kombucha and Bioactive Delivery72IMPACT SIGNAL
Evidence of global relevance

Development and Characterization of Kombucha Tea Nanoemulsion for Stability, Bioactive Delivery, and Functional Food Applications

Chiang Mai University researchers compared green, oolong and black tea kombuchas, then formulated the stronger in-vitro antioxidant green-tea concentrate as a nanoemulsion. Mean size was 110.03 nm, encapsulation efficiency 91.66%, and physical nanoscale stability persisted for six months at 4°C, with biphasic release and uptake by three cell lines. This supports a food-ingredient platform, not human health benefit.

Motorcycle Safety and Behaviour72IMPACT SIGNAL
Evidence of global relevance

Examining the Effects of Motorcyclist Risk Behavior and Protective Behavior on Motorcycle Crash Involvement

A cross-sectional survey of 2,910 active motorcyclists used a modified MRBQ and structural equation modelling. Risk behaviour was positively associated with self-reported crash involvement, while protective behaviour was inversely associated. The authors interpret protection indirectly because equipment usually reduces injury severity rather than crash occurrence. Recall-based associations do not establish causality.

AI Media and Stress-Relief Experience72IMPACT SIGNAL
Evidence of global relevance

“Temporarily Forgetting Stress”: Exploring the Multimodal Features and Audience Experience of AI-Generated Psychological Healing Videos

Content analysis of 354 AI-generated 'psychological healing' videos on Douyin and interviews with 30 viewers found hand-drawn imagery, warm colours, fantasy transformations and formulaic patterns. Simpler atmosphere-first videos drew more interaction, and some users watched during anxiety or insomnia for brief relief. This describes Chinese media experience; it does not measure symptoms or establish mental-health treatment.

Evidence of global relevance

Genome-guided characterization of Weissella species highlights strain-specific functional traits relevant to food fermentation and probiotics

Comparative analysis of 347 high-quality Weissella genomes across 16 species found an open pan-genome and extensive accessory diversity. EPS loci had six architectures, and stress, vitamin and GIT-tolerance markers were unevenly distributed. Most genomes lacked detectable AMR or virulence genes under applied criteria. The findings support genome-guided strain prioritisation, not in-silico certification of safety or probiotic function.

Stem Cells and Dopaminergic Neurons72IMPACT SIGNAL
Evidence of global relevance

Differentiation potential of human amniotic fluid derived-mesenchymal stem cells into dopaminergic neurons

Chiang Mai University researchers induced human amniotic-fluid mesenchymal stem cells to adopt neuron-like morphology and upregulate nestin, β-III-tubulin and tyrosine hydroxylase, with corresponding immunofluorescent proteins. This shows in-vitro differentiation potential, not functional dopaminergic neurons, safety or Parkinson's disease therapy.

Electrocatalysis and Urea Oxidation72IMPACT SIGNAL
Evidence of global relevance

Synergistic Combination of Triazole and BDC-MOF with TM-LDH in a One Pot for Improved Electrocatalytic Urea Oxidation

One-pot synthesis of MgZnFe-LDH with BDC-MOF or 1,2,4-triazole showed that the LDH/triazole composite formed a porous network, reduced sheet restacking and delivered up to 202 mA/cm² for urea oxidation at 1.0 M urea, with 0.41 V onset and 94% retention after 100 cycles. These are electrode tests in alkaline electrolyte, not a complete urea fuel cell.

Evidence of global relevance

Fluorescent Carbon Dots from Cassava Peel Biomass for Enhanced Latent Fingerprint Visualization

Thai researchers converted cassava peel into fluorescent carbon dots by 360 W microwave pyrolysis for nine minutes. The dots emitted blue light at 470 nm under 365 nm excitation with 31% quantum yield. Incorporated into small-particle reagent, they visualised latent-fingerprint ridges and minutiae on glass under UV. This is a limited-surface proof of concept, not a blind forensic validation.

CFD and Cyclone Separators72IMPACT SIGNAL
Evidence of global relevance

Reassessment of eddy viscosity turbulence models as alternatives to Reynolds stress models for gas cyclone separator CFD simulations

This CFD study compared multiple turbulence models against experimental data for a 0.29 m Stairmand cyclone. Appropriate discretisation improved some EVMs, and realizable k-epsilon with curvature correction matched linear/quadratic pressure-strain RSM mean-flow accuracy under the studied conditions with less computation. It challenges routine RSM preference but does not cover every cyclone or particle regime.

Evidence of global relevance

Condition-Dependent Aqueous Recovery of Crude Phycoerythrin and Antioxidant-Associated Co-Extractives from Sun-Dried Halymenia Biomass

Aqueous phosphate-buffer extraction of sun-dried Halymenia durvillei found that 1:25 at 35°C for 48 hours in the first cycle best favoured phycoerythrin concentration, yield, purity index and soluble protein. Some 1:50 conditions instead favoured phenolic/flavonoid-equivalent and antioxidant responses, showing that all product targets cannot be co-optimised.
