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

J Morphol
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.

Cytotoxin antibody-based colourimetric sensor for field-level differential detection of elapid among big four snake venom.

PLoS Neglected Tropical Diseases, 2021
Development of a rapid, on-site detection tool for snakebite is highly sought after, owing to its clinically and forensically relevant medicolegal significance.

An immunoinformatic approach to assessing the immunogenic capacity of alpha-neurotoxins in elapid snake venoms

Frontiers in Pharmacology, 2023
Introduction: Most elapid snakes produce venoms that contain alpha-neurotoxins (α-NTXs), which are proteins that cause post-synaptic blockade and paralysis in snakebite envenoming.

Diversification rates and phenotypic evolution in venomous snakes (Elapidae) [PDF]

Royal Society Open Science, 2016
The relationship between rates of diversification and of body size change (a common proxy for phenotypic evolution) was investigated across Elapidae, the largest radiation of highly venomous snakes.

Inflammation induced by snake venoms optimizes envenomation. [PDF]

J Physiol
Abstract figure legend Schematic illustrating mechanisms underlying direct vascular absorption and subsequent movement of venom toxins into the tissues consequent to snakebite. A, snakebite into prey deposits venom toxins into the tissue interstitium, with the venom then causing acute inflammation primarily in venules.

Pro-inflammatory activities in elapid snake venoms [PDF]

Toxicon, 1994
Snake venoms from the genera Micrurus (M. ibiboboca and M. spixii) and Naja (N. naja, N. melanoleuca and N. nigricollis) were analysed, using biological and immunochemical methods, to detect pro‐inflammatory activities, cobra venom factor (COF), proteolytic enzymes, thrombin‐like substances, haemorrhagic and oedema‐producing substances.

Comparative venom toxin analyses of Nigerian viperidae and elapidae snakes

Scientific African, 2023
Envenoming by snakebite is a serious health problem that maims and kills a large number of people, primarily in rural areas of developing African countries. The first comparative venom proteomic analyses of four snakes from the viperidae (E.

Rapid Progressive Course of Naja Naja Oxiana-bitten Patient [PDF]

Journal of Kerman University of Medical Sciences, 2022
Cases of snakebites especially with an elapidae are considered as a medical emergency. However, in some cases of elapidae envenomation, bite signs might be unpredictable.Case: Dorsal surface of the second finger of a 39-year-old man was bitten by N. Naja

Monkeying around with venom: an increased resistance to α-neurotoxins supports an evolutionary arms race between Afro-Asian primates and sympatric cobras

BMC Biology, 2021
Background Snakes and primates have a multi-layered coevolutionary history as predators, prey, and competitors with each other. Previous work has explored the Snake Detection Theory (SDT), which focuses on the role of snakes as predators of primates and ...

Crystal structure and functional characterization of an Asp49 phospholipase A₂ from the bushmaster (Lachesis muta). [PDF]

Acta Crystallogr F Struct Biol Commun
The crystal structure of an Asp49 phospholipase A2 from L. muta is reported, revealing a tetrameric assembly, catalytic conservation and a polarized electrostatic surface potentially linked to membrane targeting.Snake‐venom phospholipases A2 (PLA2s) are small, structurally conserved enzymes that contribute significantly to the pathophysiology of ...
