2. Effects of Brazilian scorpion venoms on the central nervous system
Abstract In Brazil, the scorpion species responsible for most severe incidents belong to the Tityus genus and, among this group, T. serrulatus, T. bahiensis, T. stigmurus and T. obscurus are the most dangerous ones. Other species such as T. metuendus, T. silvestres, T. brazilae, T. confluens, T. costatus, T. fasciolatus and T. neglectus are also found in the

3. Tityus serrulatus envenoming in non-obese diabetic mice: a risk factor for severity
Abstract Background In Brazil, accidents with venomous animals are considered a public health problem. Tityus serrulatus (Ts), popularly known as the yellow scorpion, is most frequently responsible for the severe accidents in the country. Ts envenoming can cause several signs and symptoms classified according to their clinical manifestations as mild, moder

4. Partial purification and functional characterization of Ts19 Frag-I, a novel toxin from Tityus serrulatus scorpion venom
Abstract Background The yellow scorpion Tityus serrulatus (Ts) is responsible for the highest number of accidents and the most severe scorpion envenoming in Brazil. Although its venom has been studied since the 1950s, it presents a number of orphan peptides that have not been studied so far. The objective of our research was to isolate and identify the com

5. Immunomodulatory activity of Tityus serrulatus scorpion venom on human T lymphocytes
Abstract Background Tityus serrulatus scorpion venom (TsV) contains toxins that act on K + and Na + channels and account for the venom’s toxic effects. TsV can activate murine peritoneal macrophages, but its effects on human lymphocytes have been poorly investigated. Considering that lymphocytes may play an important role in envenomation, we assessed whet

6. Clinical update on scorpion envenoming
Abstract: Scorpion stings are currently the leading cause of venom-related injury to humans in Brazil and are a significant public health problem globally. Only scorpions of the Tityus genus are of medical importance in Brazil, and Tityus serrulatus is responsible for the most serious envenomations and deaths. The toxic effects of scorpion envenomation are d

7. Arthropod venom Hyaluronidases: biochemical properties and potential applications in medicine and biotechnology
AbstractHyaluronidases are enzymes that mainly degrade hyaluronan, the major glycosaminoglycan of the interstitial matrix. They are involved in several pathological and physiological activities including fertilization, wound healing, embryogenesis, angiogenesis, diffusion of toxins and drugs, metastasis, pneumonia, sepsis, bacteremia, meningitis, inflammatio

9. Mild reproductive effects of the Tityus bahiensis scorpion venom in rats
BackgroundScorpion envenoming is a public health problem in Brazil, whereTityus serrulatus and T. bahiensisare considered the most dangerous scorpions. They are well adapted to urbanized environments, and there is an increasing probability of human exposure to these venoms, including during pregnancy. Not much is known about the effects of prenatal exposure

10. Clinical aspects of envenomation caused by Tityus obscurus (Gervais, 1843) in two distinct regions of Pará state, Brazilian Amazon basin: a prospective case series
Background : Scorpion envenomations are a major public health problem in Brazil, whose most dangerous cases are attributable to the genus Tityus. This study was designed to compare the clinical and demographic features of envenomations by 77tyus obscurus in two areas of the state of Pará located in the Amazon basin. Were compared demographic findings, l

11. Equipment based on high power UV and white light LEDs to collect and observe scorpions (Arachnida: Scorpiones) and other fluorescent organisms
We introduce a new, high quality, low cost and versatile LEDs-based handset device that emits high power UV and white light, which can be used interchangeably. It offers power control and has long battery life. Even though it is optimized to detect and collect scorpions under low light conditions, it can also be used with other groups of fluorescent organism

12. Efeito do veneno de Tityus serrulatus em camundongos selecionados geneticamente para máxima ou mínima resposta inflamatória. / Effect of Tityus serrulatus venom in mice genetically selected for maximal or minimal inflammatory response.
Tityus serrulatus é o principal causador de acidentes por escorpião no Brasil. O seu veneno pode causar reações sistêmicas severas, como disfunção cardíaca e edema pulmonar agudo. Sabendo que fatores genéticos podem influenciar na gravidade dos sintomas apresentados pelos pacientes, o objetivo deste estudo foi avaliar a ação do veneno de T. serrul
