Theraphosid spiders (tarantulas) are venomous arthropods found in most tropical and subtropical regions of the world. Tarantula venoms are a complex cocktail of toxins with potential use as pharmacological tools, drugs and bioinsecticides. Although numerous toxins have been isolated from tarantula venoms, little research has been carried out on the venom of Australian tarantulas. We therefore i...

Muscle fibers of the tarantula femur exhibit structural and biochemical characteristics similar to those of other long-sarcomere invertebrate muscles, having long A-bands and long thick filaments. 9-12 thin filaments surround each thick filament. Tarantula muscle has a paramyosin:myosin heavy chain molecular ratio of 0.31 +/- 0.079 SD. We studied the myosin cross-bridge arrangement on the surfa...

BACKGROUND In practically every human culture, the use of arthropods as medicinal resources has been reported. In Mexico, the Mayan people mainly use plants but occasionally also animals and minerals in their medicine. This article is the first to report the traditional use of the tarantula Brachypelma vagans by medicine men in the Chol community, an ancient indigenous group that inhabits the s...

Web crawlers today suffer from poor navigation techniques which reduce their scalability while crawling the World Wide Web (WWW). In this paper we present a web crawler named Tarantula that is scalable and fully configurable. The work on Tarantula project was started with the aim of making a simple, elegant and yet an efficient Web Crawler offering better crawling strategies while walking throu...

i read with great interest the case report titled “periumbilical pain with radiation to both legs following tarantula bite; a case report” published in emergency journal. tarantula spiders are not medically important except for some very limited species, which do not exist in iran. solifugae -or rotails as they are called in iran- are in fact another group of animals also called camel spiders (...

Commonly reported gender effects for differential vulnerability for anxiety may relate to gender socialization processes. The present study examined the relationship between gender role and fear under experimental conditions designed to elicit accurate fear reporting. Undergraduate students (N=119) completed several self-report measures and a behavioral avoidance task (BAT) with a tarantula whi...

This paper applies a routing strategy based on Tarantula Mating Behavior as proposed by the authors, Bandyopadhyay and Bhattacharya [1], on a manufacturing network. The particular behavior which is of interest is that the female Tarantula spider sometimes eats the male Tarantula just after mating for satisfying immediate need for food or for genetic purpose. This interesting behavior has been s...

Tarantula toxins that bind to voltage-sensing domains of voltage-activated ion channels are thought to partition into the membrane and bind to the channel within the bilayer. While no structures of a voltage-sensor toxin bound to a channel have been solved, a structural homolog, psalmotoxin (PcTx1), was recently crystalized in complex with the extracellular domain of an acid sensing ion channel...
