Development of an Immunofluorescence Lateral Flow Assay for Detecting Four Medically Important Snake Venoms in China

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Snakebite envenomation requires rapid venom identification for effective treatment, a need unmet by current diagnostics in China. This study aimed to develop a rapid, multiplex immunofluorescence lateral flow assay for the simultaneous detection of four major venomous snakes: Deinagkistrodon acutus, Bungarus multicinctus, Naja atra, and Agkistrodon ...

Phylogenetic Relationships of Elapid Snakes Based on Cytochrome b mtDNA Sequences [PDF]

, 2015
Published molecular phylogenetic studies of elapid snakes agree that the marine and Australo-Melanesian forms are collectively monophyletic. Recent studies, however, disagree on the relationships of the African, American, and Asian forms.

Quaternary Habitat Fluctuations and Demographic Dynamics in Turtles Inferred From Environmental Niche Modelling and Whole Genome Data

Molecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Quaternary climatic fluctuations had a substantial influence on ecosystems, species distribution, phenology and genetic diversity, driving extinction, adaptation and demographic shifts during glacial periods and postglacial expansions. Integration of genomic data and environmental niche modelling can provide valuable insights on how organisms ...

Coral snake venoms: mode of action and pathophysiology of experimental envenomation

Revista do Instituto de Medicina Tropical de São Paulo, 1987
Coral snakes, the New World Elapidae, are included in the genera Micniroides and Micrurus. The genus Mlcrurus comprises nearly all coral snake species and those which are responsible for human snake-bite accidents.

Exceptional Visual‐Opsin Coexpression and Phenotypic Diversity in Outer‐Retinal Photoreceptors of Caenophidian Snakes

Journal of Comparative Neurology, Volume 533, Issue 10, October 2025.
In snakes, profound differences in retinal architecture are observed between diurnal and nocturnal species. Additionally, in the rod‐dominated retinas of nocturnal snakes, coexpression of the cone opsins SWS1 and LWS in individual cones is common, while rhodopsin (RH1) is restricted to typical rods.

Surface Topography and Ultrastructure of the Spectacular Cells in the Eyes of Land and Sea Snakes (Squamata, Reptilia): Functional Adaptations of Micro‐Ornamentation

Journal of Morphology, Volume 286, Issue 9, September 2025.
ABSTRACT Although the surface micro‐ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub‐spectacular space. The surface ultrastructure of the “Oberhäutchen” of the spectacle is

Epidermal scale growth, allometry and function in non‐avian dinosaurs and extant reptiles

Journal of Anatomy, Volume 247, Issue 2, Page 250-283, August 2025.
Scale shapes in non‐avian dinosaurs and extant reptiles are mostly retained through growth. However, positive scale allometry and proportional differences in scale breadth are also detected, which are likely associated with changing body proportions. Based on their generally conserved morphology and impracticality for visual display, the enlarged size ...
