Four Countries Have Antimicrobial-Stewardship Policies, but 16 Hospitals Average 72% Implementation and Training Lags

This study linked national policy, hospital systems, and provider behaviour in Indonesia, Nepal, Thailand, and Viet Nam during 2022–2023. It included 486 participants across 16 hospitals. All countries had antimicrobial-stewardship policies, but financing, enforcement, training, microbiology-data use, and inter-programme coordination were uneven. Hospitals averaged 72% on G-ASET, with tracking and reporting highest at 75% and training lowest at 66%. The two Thai hospitals scored 81.3% and 80.6% overall, yet both scored only 50% for training. These results identify actionable system gaps; they do not experimentally show that any intervention reduced antibiotic use, resistance, or mortality.

Deep-Eutectic Solvents and Biocatalysis73IMPACT SIGNAL
Evidence of global relevance

Spontaneous formation of highly concentrated phenylacetylcarbinol via in situ phase separation in deep eutectic solvents using Candida magnoliae whole cells

Chiang Mai University and collaborators screened nine deep-eutectic solvents with Candida magnoliae whole cells for phenylacetylcarbinol production. Choline chloride:glycerol performed best; the 20%-water system reached 148.2 mM total PAC, while a 100%-water, 1:1 DES:buffer condition improved productivity and spontaneously formed a PAC-rich top phase around 2.5 M. This integrates reaction with initial separation at laboratory scale, not yet proven sustainable at process scale.

Curcumin and Cognitive Health73IMPACT SIGNAL
Evidence of global relevance

Curcumin and Cognitive Health: Insights from Randomized Controlled Trials

This review summarises adult curcumin RCTs, with some Longvida, Theracurmin and CurQfen trials reporting improvements in memory, attention, mood, cerebral blood flow or inflammatory markers, particularly in older adults. Results vary by formulation, dose, duration and population. The abstract gives no systematic search, trial count or pooled effect, so evidence is insufficient to recommend curcumin as a cognitive enhancer.

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.

“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.

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.
