Snakebites in the Brazilian Amazon: Current Knowledge and Perspectives

Bitis gabonica Gaboon viper snake venom gland: toward a catalog for the full- length transcripts cDNA and proteins. PubMed Central. The venom gland of the snake Bitis gabonica Gaboon viper was used for the first time to construct a unidirectional cDNA phage library followed by high-throughput sequencing and bioinformatic analysis. Hundreds of cDNAs were obtained and clustered into contigs. We found mostly novel full-length cDNA coding for metalloproteases P-II and P-III classes , Lysphospholipase A2, serine proteases with essential mutations in the active site, Kunitz protease inhibitors, several C-type lectins, bradykinin-potentiating peptide, vascular endothelial growth factor, nucleotidases and nucleases, nerve growth factor, and L-amino acid oxidases. Two new members of the recently described short coding region family of disintegrin, displaying RGD and MLD motifs are reported.

On Some Phylogenetic Aspects of Coral Snake Coloration and the Associated Mimicry Complex

Communities are complex and dynamic systems that change with time. The first attempts to explain how they were structured involve contemporary phenomena like ecological interactions between species e. Recently, the deep history hypothesis has emerged, which suggests that profound differences in the evolutionary history of organisms resulted in a number of ecological features that remain largely on species that are part of existing communities.

The Western Ghats are well known as a biodiversity hotspot, but the full extent of its snake diversity is yet to be uncovered. Here, we describe a new genus and species of vine snake Proahaetulla antiqua gen. It was found to be a member of the Ahaetuliinae clade, which currently comprises the arboreal snake genera Ahaetulla , Dryophiops , Dendrelaphis and Chrysopelea , distributed in South and Southeast Asia. Proahaetulla shows a sister relationship with all currently known taxa belonging to the genus Ahaetulla , and shares ancestry with Dryophiops.

The ability to sense infrared thermal radiation evolved independently in two different groups of snakes, Boidae boas and pythons and Crotalinae pit vipers. The more advanced infrared sense of pit vipers allows these animals to strike prey accurately even in the absence of light, and detect warm objects from several meters away.

 В чем дело? - Беккер не рассчитывал, что все это займет так много времени, и теперь опаздывал на свой обычный субботний теннисный матч. Часовой пожал плечами. - С вами хочет поговорить начальник шифровалки. Она сейчас будет. - Она? - Беккер рассмеялся. Он не заметил в АНБ ни одного существа женского пола. - Вас это смущает? - раздался у него за спиной звонкий голос.

Наконец Беккер дошел до конца темного коридора и толкнул чуть приоткрытую дверь слева. Комната была пуста, если не считать старой изможденной женщины на койке, пытавшейся подсунуть под себя судно. Хорошенькое зрелище, - подумал Беккер.  - Где, черт возьми, регистратура. За едва заметным изгибом коридора Беккер услышал голоса.

Он принял решение. Под визг покрышек, в снопе искр Беккер резко свернул вправо и съехал с дороги. Колеса мотоцикла подпрыгнули, ударившись о бетонное ограждение, так что он едва сумел сохранить равновесие. Из-под колес взметнулся гравий.

Он хотел отдать кольцо. Какие же страшные были у него руки. - Вот тут-то вы и рассмотрели его кольцо.

И ради этого стоило убивать. Когда Беккер наконец вышел из Гиральды в Апельсиновый сад, утреннее солнце уже нещадно пекло. Боль в боку немного утихла, да и глаза как будто обрели прежнюю зоркость.

 Ты сошла с ума! - крикнул в ответ Хейл.  - Я вовсе не Северная Дакота! - И он отчаянно забился на полу. - Не лги, - рассердилась Сьюзан.

    Pit vipers (Viperidae: Crotalinae) represent a particularly interesting taxon in which to study patterns in learning as they are widely studied, have.

    Rattlesnakes uniformly decreased their decision-making time in a thermal maze. •. Learning occurred after one trial. •. Nonrattlesnake pit vipers did not modify their.

    Although important efforts were carried out during the past decades in Brazil to understand and control snakebite envenomings, important gaps remain for the fulfillment of these goals, particularly in the Amazon region.

    However, this apparent phylogenetic pattern must be interpreted conservatively, as we only surveyed a single species of true viper and we did not examine.
