Hydrolysis of peptides by Crotalidae and Viperidae venoms
Toxicon, 1968Abstract Peptidase activities of nine Viperidae and thirteen Crotalidae venoms were investigated using twenty-nine dipeptides, six tripeptides, and one tetrapeptide. Only five peptides were not hydrolyzed by any of the snake venoms investigated. Relatively few differences in substrate specificities were found for snake venoms regardless of species ...

Anticoagulant Factors from Viperidae Venoms
Thrombosis and Haemostasis, 1972SummaryTwo proteins presenting anticoagulant activities were isolated from Viperidae venoms : one from Vipera aspis, the other from Vipera berus. They interfere with the formation of prothrombinase. Their inhibitory effect results from a specific action of a complex which blocks the active sites of phospholipids.

Phylogeny of the vipers of the Caucasus (Reptilia, Viperidae)
Zoologica Scripta, 1994Phylogenetic relationships for five taxa of Palearctic vipers (genus Vipera) from the Caucasian region were revealed by cladistic analyses of separate and combined morphological and biochemical characters. The different data sets yielded largely congruent cladograms. Vipera berus from Sweden was included as an ingroup and V. aspis was used for outgroup

Viperidae Envenomation in India
2014The estimated incidence of venomous snakebites in India is around 300,000 annually and the overall mortality is between 30,000 and 50,000. The majority of this is due to Viperidae envenomation. There is a lack of consensus regarding the management protocol. The symptoms, signs, diagnosis, and management of Viperidae envenomation are discussed.

Heterochromosomen beiVipera berus L. (Viperidae, Serpentes)
Experientia, 1962A dimorphic pair of chromosomes was found among the macrochromosomes in mitosis of females ofVipera berus L. It corresponds to a pair of medium-sized chromosomes in the male. The conclusion is drawn that females are heterogametic (ZW-type), males being homogametic (ZZ-type).

Mitochondrial genome ofProtobothrops mangshanensis(Squamata: Viperidae: Crotalinae)
Mitochondrial DNA, 2013Protobothrops maolanensis was recently described from Guizhou, southwestern China. In this study, the complete mitochondrial genome of P. maolanensis had been determined. The circle genome with the 17,231 bp total length contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 2 control regions.

Bayesian mixed models and the phylogeny of pitvipers (Viperidae: Serpentes)
Molecular Phylogenetics and Evolution, 2006The subfamily Crotalinae (pitvipers) contains over 190 species of venomous snakes distributed in both the Old and New World. We incorporated an extensive sampling of taxa (including 28 of 29 genera), and sequences of four mitochondrial gene fragments (2.3kb) per individual, to estimate the phylogeny of pitvipers based on maximum parsimony and Bayesian ...

Microvesicles in the venom of Crotalus durissus terrificus (Serpentes, Viperidae)
Toxicon, 2007Microvesicles with electron-dense content are consistently observed by transmission electron microscopy on the luminal face of secretory cells of venom glands of viperid snakes. In this work, we evaluated their presence in Crotalus durissus terrificus venom glands and also in freshly collected venom.

Viperidae Zehirli Isırıkları Tedavi Yönetimi
2015Snake bite poisoning is a serious health problem and can be seen all over the world. The Viperidae family is responsible for the majority of venomous snake bite cases in Anatolia. There is a very low complication rate when appropriate treatment is administered, otherwise, serious sequelae can occur.
