An in vivo examination of the differences between rapid cardiovascular collapse and prolonged hypotension induced by snake venom

Scientific Reports, 2019
We investigated the cardiovascular effects of venoms from seven medically important species of snakes: Australian Eastern Brown snake (Pseudonaja textilis), Sri Lankan Russell’s viper (Daboia russelii), Javanese Russell’s viper (D.

A genus‐wide bioactivity analysis of daboia (Viperinae: Viperidae) viper venoms reveals widespread variation in haemotoxic properties [PDF]

, 2021
The snake genus Daboia (Viperidae: Viperinae; Oppel, 1811) contains five species: D. deserti, D. mauritanica, and D. palaestinae, found in Afro‐Arabia, and the Russell’s vipers D. russelii and D. siamensis, found in Asia. Russell’s vipers are responsible

Conservation of Major Satellite DNAs in Snake Heterochromatin

Animals, 2023
Repetitive DNA sequences constitute a sizeable portion of animal genomes, and tandemly organized satellite DNAs are a major part of them. They are usually located in constitutive heterochromatin clusters in or near the centromeres or telomeres, and less ...

Survey for snake-tick (Ixodida) association in some districts of West Bengal, India

Persian Journal of Acarology, 2021
During a study, two tick species viz. Amblyomma gervaisi and Am. helvolum were collected from snakes covering 15 species belonging to 12 genera. The period of extended survey of snake- tick association was undertaken from 2009 to 2015 covering both ...

Tracing Ancient Migration Routes: Did Gloydius Pitvipers Disperse Across Paleo‐Tibet Through Temperate and Subtropical Corridors?

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We investigated the evolutionary and biogeographic history of Himalayan and Hindu Kush Gloydius pitvipers by integrating time‐calibrated phylogenetic analyses with paleoclimatic reconstructions and species distribution modeling. Our results suggest an early Miocene origin in East and Southeast Asia, followed by westward dispersal across Paleo‐Tibet via

Immunological Cross‐Reactivity and Neutralizing Efficacy of Antivenom Against Five Medically Important Iranian Viper Venoms

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Investigating Iranian viper venoms reveals compositional and antigenic diversity impacting antivenom efficacy. The study highlights the need to incorporate both broadly cross‐reactive and specifically under‐represented venoms into immunization mixtures to optimize paraspecific protection strategies.

D. russelii Venom Mediates Vasodilatation of Resistance Like Arteries via Activation of K_v and K_Ca Channels

Toxins, 2019
Russell’s viper (Daboia russelii) venom causes a range of clinical effects in humans. Hypotension is an uncommon but severe complication of Russell’s viper envenoming. The mechanism(s) responsible for this effect are unclear.

Collocation of avian and mammal antibodies to develop a rapid and sensitive diagnostic tool for Russell's Vipers Snakebite.

PLoS Neglected Tropical Diseases, 2020
Russell's vipers (RVs) envenoming is an important public health issue in South-East Asia. Disseminated intravascular coagulopathy, systemic bleeding, hemolysis, and acute renal injury are obvious problems that develop in most cases, and neuromuscular ...

The pro-coagulant fibrinogenolytic serine protease isoenzymes purified from Daboia russelii russelii venom coagulate the blood through factor V activation: role of glycosylation on enzymatic activity. [PDF]

PLoS ONE, 2014
Proteases from Russell's viper venom (RVV) induce a variety of toxic effects in victim. Therefore, four new RVV protease isoenzymes of molecular mass 32901.044 Da, 333631.179 Da, 333571.472 Da, and 34594.776 Da, were characterized in this study.

The Backbone of Regionalisation: Refining Axial Regionalisation Through 3D Morphometric Sampling Strategies on Elapid Snakes

Journal of Morphology, Volume 287, Issue 8, August 2026.
Using 3D geometric morphometrics on every precaudal vertebra from 12 elapid snakes, this study used segmented linear regression to test regionalisation. The results show a five‐region model is best supported, including short cervical and lumbar regions and a strong heart‐aligned boundary at approximately 20% of the pre‐caudal column.
