Severe hypertension in elapid envenomation [PDF]

Journal of Cardiovascular Disease Research, 2013
Snakebite is not an uncommon medical emergency in India; however, symptoms of autonomic dysfunction in snakebite are rare. The elapid snake envenomation is a frequent occurrence in India, and the krait bite is prevalent in the south Indian region. Here, we present three cases of snakebite with severe hypertension and requiring intravenous nitroglycerin

Occurrence and evolution of cannibal behaviour in extant snakes. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

Black-bellied Coral Snake Sinomicrurus nigriventer (Wall, 1908) (Elapidae): an extended distribution in the western Himalaya, India

Journal of Threatened Taxa, 2021
The Black-bellied Coral Snake Sinomicrurus nigriventer (Wall, 1908) was recently elevated to specific status from Himachal Pradesh where it was also known historically. We present here two individual observations of S. nigriventer from Uttarakhand State

Learning to Swim: An Exploration of the Terrestrial to Aquatic Transition in Elapids (Squamata: Elapidae) [PDF]

, 2021
Elapidae is an extremely diverse family of venomous snake that have a nearly global distribution. To conquer such wide swaths of territory the initially fossorial snakes evolved many successful strategies pertaining to reproduction, locomotion, and ...

Circular dichroic spectra of elapid cardiotoxins [PDF]

European Journal of Biochemistry, 1988
Cardiotoxins isolated from elapid snake venoms constitute a chemically homogeneous family of molecules. Within this group several biologically different subclasses exist. We report a comparative analysis of the structure of 20 cardiotoxins using circular dichroism, immunological methods and secondary‐structure prediction.

Assessing the binding of venoms from aquatic elapids to the nicotinic acetylcholine receptor orthosteric site of different prey models [PDF]

, 2020
The evolution of an aquatic lifestyle from land dwelling venomous elapids is a radical ecological modification, bringing about many evolutionary changes from morphology to diet.

ELAPID SNAKE BITE

British Journal of Anaesthesia, 1987
Four patients were admitted with respiratory muscle paralysis following an elapid snake bite. Two were treated with antivenine, repeated doses of neostigmine and artificial ventilation; the other two with artificial ventilation only. There was no clinically significant difference in recovery.

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.

Evidence for Resistance to Coagulotoxic Effects of Australian Elapid Snake Venoms by Sympatric Prey (Blue Tongue Skinks) but Not by Predators (Monitor Lizards)

Toxins, 2021
Some Australian elapids possess potently procoagulant coagulotoxic venoms which activate the zymogen prothrombin into the functional enzyme thrombin. Although the activity of Australian elapid prothrombin-activators has been heavily investigated with ...

Spectral Diversification and Trans-Species Allelic Polymorphism during the Land-to-Sea Transition in Snakes [PDF]

, 2020
Snakes are descended from highly visual lizards [1] but have limited (probably dichromatic) color vision attributed to a dim-light lifestyle of early snakes [2, 3, 4].
