Métodos de Investigación: destrezas básicas para el trabajo científico en las disciplinas biomédicas
(2020-10-01)
Esta obra didáctica nace con el objetivo de presentar a sus lectores una visión
introductoria sobre el fenómeno científico actual, sus orígenes, su contexto
costarricense, y posteriormente presentar las principales ...
Venenos de serpientes de la familia Viperidae en América: Bioquímica y fisiopatología.
(2011)
Se muestra una perspectiva general de las características bioquímicas de los principales tipos de toxinas
presentes en los venenos de vipéridos americanos y la fisiopatología de estos envenenamientos. En la preparación ...
Stable production of recombinant SARS-CoV-2 receptor-binding domain in mammalian cells with co-expression of a fluorescent reporter and its validation as antigenic target for COVID-19 serology testing
(2023-01)
SARS-CoV-2 receptor binding domain (RBD) recognizes the angiotensin converting enzyme 2 (ACE2) receptor in host cells that enables infection. Due to its antigenic specificity, RBD production is important for development ...
Comparative study of synthetic peptides corresponding to region 115-129 in Lys49 myotoxic phospholipases A2 from snake venoms
(2003)
Lys49 phospholipase A2 homologues constitute a group of catalytically-inactive proteins, present in the venoms of many
crotalid snakes, which induce myonecrosis. Current evidence supports the mapping of their toxic site ...
Isolation and characterization of basic myotoxic phospholipases A2 from Bothrops godmani (Godman's pit viper) snake venom
(1992)
Two basic myotoxic phospholipases A2 were purified to homogeneity from the venom of Bothrops godmani from Costa Rica by ion-exchange chromatography on CM-Sephadex. They have molecular weights of 14,300 (myotoxin I) and ...
Immunochemical properties of the N-terminal helix of myotoxin II, a lysine-49 phospholipase A2 from Bothrops asper snake venom
(2001)
Myotoxic class II phospholipases A2 from snake venoms can be divided into Asp49 and Lys49 types. The latter, including
Bothrops asper myotoxin II, exert membrane damage despite lacking catalytic activity. A heparin-binding, ...
Innovative immunization strategies for antivenom development
(2018)
Snakes, scorpions, and spiders are venomous animals that pose a threat to human
health, and severe envenomings from the bites or stings of these animals must be treated with
antivenom. Current antivenoms are based on ...
Comparison of biochemical and cytotoxic activities of extracts obtained from dorsal spines and caudal fin of adult and juvenile non-native Caribbean lionfish (Pterois volitans/miles)
(2017-10)
Pterois volitans/miles lionfish (adult and juvenile) dorsal spines and caudal fin extracts were compared in
their general composition, enzymatic activities and hemolytic and cytotoxic effects on bovine aortic
endothelial ...
Inhibitory effect of fucoidan on the activities of crotaline snake venom myotoxic phospholipases A2
(2003)
Myotoxic phospholipases A2 account for most of the muscle necrosis that results from envenenomation by crotaline snakes. In this study,
we investigated the protective effect of fucoidan, a natural sulfated polysaccharide ...
Venom of the neotropical rattlesnake, Crotalus culminatus: Intraspecific variation, neutralization by antivenoms, and immunogenicity in rabbits
(2024)
Crotalus culminatus is a medically significant species of rattlesnake in Mexico [1]. While the proteomic composition of its venom has been previously reported for both juvenile and adult specimens, there has been limited ...
