Studies of event-related potentials in humans have established larger early posterior negativity (EPN) in response to pictures depicting snakes than to pictures depicting other creatures. Ethological research has recently shown that macaques and wild vervet monkeys respond strongly to partially exposed snake models and scale patterns on the snake skin. Here, we examined whether snake skin patte...

ABSTRACT Dot-ELISA test is developed in mice models to identify cobra and viper snake species in snake bite cases. Simplicity and cost effective qualities of this test showed great promises to be utilized in the field which can be useful for farmers, plantation workers and fisherman who are working in field and become victim of snake bite cases. Dot-ELISA test can be an alternative solution to ...

E nvenoming resulting from snake bites is an important public health hazard in many regions, particularly in tropical and subtropical countries [1–3]. Although antivenoms are being produced by various laboratories in every continent, the burden of snake bite envenoming— causing both morbidity and mortality—still has a great impact on the population and on health-care systems, especially in Afri...

In nature, snakes can gracefully traverse a wide range of different and complex environments. Snake robots that can mimic this behaviour could be fitted with sensors and transport tools to hazardous or confined areas that other robots and humans are unable to access. In order to carry out such tasks, snake robots must have a high degree of awareness of their surroundings (i.e., perception-drive...

The present study used experimental infections to compare the life cycles and life histories of 6 Rhabdias spp. infecting snakes and anurans. Free-living development of anuran lungworms was primarily limited to heterogonic reproduction, and females utilized matricidal endotoky exclusively, whereas snake lungworms primarily reproduced homogonically and, when heterogonic reproduction occurred, fe...

Snakebites can present local or systemic envenomation, while neurotoxicity and respiratory paralysis are the main cause of death. The mainstay of management is anti-snake venom (ASV), which is highly effective, but liable to cause severe adverse reactions including anaphylaxis. The types of adverse reaction to polyvalent anti-snake venom have not been previously studied in Bangladesh. In this p...

the myocardial effect of snake venoms is considered as one of the most common pathogenesis in many cases of snake envenomation. this study was under taken to investigate the effects of snake (naja naja oxiana) venom on cardiac function in experimental animals. the blood samples from all the rabbits were collected before venom injection and then 140 µg/kg venom of snake (naja naja oxiana) was in...

snake robots are hyper-redundant robots that are connected with one or two dof joints. they offer a number of potential advantages beyond the capabilities of most wheeled and legged robots. in this paper, kinematics and dynamics of a planar multi-link snake robot in worm-like locomotion on an inclined surface is investigated. in this locomotion, snake robot is able to move in the vertical plane...

Elapid snake envenomation in dogs is a commonly occurring yet poorly described clinical entity. Twelve species of dangerously venomous elapid snakes are found in New South Wales that are capable of causing disease in dogs. Geographical distribution of these species varies, as does their venom composition and systemic envenomation syndromes produced in target species. Elapid venom may be divided...

Snake bite is a common cause of hospital admission in Sri Lanka. Despite this, there have been no countrywide studies or national estimates of disease burden due to snake bites in Sri Lankan hospitals. We assessed the disease burden due to snake bite in our hospitals and estimated the frequency of admissions due to bites by different snake species. Sri Lanka was divided into four zones based on...
