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.

Efficacy and safety of needle-free jet injection of self-crosslinking hyaluronic acid for facial fine wrinkles and skin texture: 12-week clinical outcomes in Asian women

Thirty Asian women aged 40-55 with Fitzpatrick III-IV skin received three needle-free jet sessions of self-crosslinking hyaluronic acid at four-week intervals. At week 12, 3D wrinkle and texture measures improved across malar and pericommissural regions; investigator severity fell from 7.28 to 4.32, and 60% reported moderate-to-marked improvement. Treatment reactions were mild and transient. The single-arm design cannot separate treatment effects from time or expectation.

Climate thresholds and yield elasticity of durian, mangosteen, and coffee under hydroclimatic variability in Thailand

Meteorological observations from 56 stations were linked to provincial yields during 2008-2024 using nonlinear, lagged, elasticity and climate-risk analyses. Simple correlations were generally weak. Nonlinear models suggested approximate temperature turning points of 28.0 C for durian, 27.3 C for mangosteen and 26.6 C for coffee, with humidity turning points around 76-78%. The authors correctly frame these as statistical response indicators, not fixed physiological optima.

Pristaulacus chiangmaiensis Turrisi & Ghafouri Moghaddam 2026, sp. nov.

Pristaulacus chiangmaiensis is described as a new species from a female holotype in Huai Nam Dang National Park, Chiang Mai, and a female paratype from Doi Phu Kha National Park, Nan. Diagnostic evidence combines black-orange coloration, head and occipital-groove shape, a long petiole and an ovipositor 1.3 times forewing length. The paratype barcode differed 12.95% from the nearest BOLD Aulacidae sequence, with a reported 14.3% distance from P. vilhelmseni, complementing morphology.

Pristaulacus erythrocephalus Cameron 1905

This treatment documents Pristaulacus erythrocephalus using a male from Songkhla and a female from Khao Pu-Khao Ya National Park, Trang. The large wasp has a reddish-orange head and thorax with black posterior structures and diagnostic morphology. A Thai barcode differed 18.51% from its nearest Aulacidae sequence in BOLD. The record supports a wider Southeast Asian distribution; the host is unknown.

Pristaulacus vilhelmseni Turrisi & Smith 2011

Pristaulacus vilhelmseni is newly recorded from Thailand based on a female from Doi Inthanon National Park, Chiang Mai; its holotype is from Laos. Diagnostic traits include a mostly black body, dark wing band, U-shaped occipital groove, slender petiole and an ovipositor 1.1 times forewing length. The Thai barcode showed a reported 14.3% divergence from P. chiangmaiensis, extending the known range across the Mekong region.

Pristaulacus iosephi Turrisi & Madl 2013

This treatment describes Pristaulacus iosephi from a female holotype collected in Fang, Chiang Mai, in 1958. The roughly 17-mm wasp is mostly black, has extensive brown wing infuscation, two tooth-like pronotal processes, an elevated overhanging mesonotum, a six-toothed tarsal claw and an ovipositor equal to forewing length. It is known from Chiang Mai and Yunnan, belongs to the P. comptipennis group, and has no known host.

Classifying the Likelihood of Failure in Preliminary Tree Assessment: A Species-Specific Meta-Decision Tree Protocol

Field observations from 1,193 trees representing four common campus species were scored with expert-weighted preliminary indicators. Species-specific decision trees were combined into a meta-classifier for unlikely, possible or likely failure. Overall accuracy was 79.03% with Cohen’s kappa 0.580. The model was more reliable at the unlikely and likely extremes and underdetected possible failures, so it is a prioritization aid rather than a replacement for advanced diagnostics.

Geographical Classification of Okra ( Abelmoschus esculentus ) by Chemometric Analysis of Polyphenolic Profiles Obtained from HPLC-DAD and LC-MS

An optimized, greener extraction recovered more total flavonoids than the conventional method. HPLC-DAD and LC-MS then profiled okra flavonoids, including quercetin and catechin derivatives. PCA explored variation and LDA classified country of origin, locations within Thailand and one-versus-all tasks, with reported classification and prediction accuracy of 80-100%. This is promising for geographical-indication support but needs independent, multi-season validation.

Inflammatory Bowel Disease Is Associated With an Increased Risk of End‐Stage Renal Disease: A Population‐Based Cohort Study

Linked Manitoba data from 1984-2023 compared 12,639 people with IBD with 126,180 matched controls. Dialysis occurred in 1.48% versus 0.82% and kidney transplantation in 0.25% versus 0.10%. IBD remained associated with ESRD (adjusted HR 1.53), with a stronger estimate for Crohn’s disease than ulcerative colitis. Diabetes, hypertension and heart failure remained major predictors; treatment and surgery associations may reflect disease severity rather than causal harm.

Genomic surveillance of carbapenem-resistant Acinetobacter baumannii from bloodstream infections in Thailand reveals widespread dissemination of blaNDM–harboring mobile genetic elements

Whole-genome surveillance of 41 carbapenem-resistant A. baumannii bloodstream isolates collected across Thailand in 2020-2024 found widespread international clone II (ST2). Resistance was dominated by blaOXA-23 with intrinsic blaOXA-66 and a penicillin-binding-protein mutation. A conserved blaNDM-5 mobile element appeared across ST2 sublineages and regions, consistent with horizontal spread followed by clonal expansion; blaNDM-1 was less frequent and linked to Tn125 in ST2 and ST16.
