Abstract. Prakrongrak N, Boonsoong B, Monthatong M. 2023. Genetic diversity and phylogenetic analysis of mayfly Caenis (Insecta: Ephemeroptera) using Cytochrome C Oxidase I (COI) 12s rRNA genes from Thailand. Biodiversitas 24: 1989-1997. Mayflies in genus Caenisis one the top fifth species richnessbelonged to Family Caenidae. The present study aimed use partial mitochondrial COxidase subunit nu...

We report measurements of the absolute energies hyperfine components $12s \ ^2S_{1/2}$ and $13s levels atomic cesium, $^{133}$Cs. Using frequency difference between these components, we determine coupling constants for states, values with a relative uncertainty $\sim$0.06 %. also examine structure $11d ^2D_{J}$ ($J=3/2, 5/2$) resolve sign ambiguity from previous states. derive new, high precisi...

BACKGROUND Percutaneous transluminal coronary angioplasty (PTCA) is a widely used and important method of reperfusing coronary arteries. However, it is also associated with serious complications such as acute reocclusion and accelerated restenosis. The factors as well as the mechanisms involved in PTCA-associated complications remain to be fully elucidated. Because peptidoleukotrienes and lipox...

We investigated the taxonomic status of recently described kukri snake Oligodon arenarius Vassilieva, 2015 and morphologically similar macrurus (Angel, 1927), two species endemic to southern coast Vietnam. Based on phylogenetic analyses using three mitochondrial genes (12S–16S rRNA, cytochrome b ), we recovered O. in a clade within cyclurus-taeniatus group, agreeing with previous intrageneric c...
