Heterologous hyperimmune polyclonal antibodies against SARS-COV-2: A broad coverage, affordable, and scalable potential immunotherapy for Covid-19
(2021-09)
The emergence and dissemination of the severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) and the resulting COVID-19 pandemic triggered a global public health crisis.
Although several SARS-CoV-2 vaccines have ...
Venom characterization of the bark scorpion Centruroides edwardsii (Gervais 1843): composition, biochemical activities and in vivo toxicity for potential prey
(2019)
In this study, we characterize the venom of Centruroides edwardsii, one of the most abundant scorpions in urban
and rural areas of Costa Rica, in terms of its biochemical constituents and their biological activities. C. ...
Mevalonate pathway as a novel target for the treatment of metastatic gastric cancer
(2020-10)
Gastric mucosa tumors may present as two distinct major entities: Diffuse and intestinal subtypes. There is no
standard treatment for advanced or metastatic gastric cancer. The mevalonate pathway and cholesterol homeostasis ...
Biochemical characterization of the venom of Central American scorpion Didymocentrus krausi Francke, 1978 (Diplocentridae) and its toxic effects in vivo and in vitro
(2019)
non-buthid venoms, for which knowledge is scarce. In this work, we characterized the venom of a Diplocentridae
species, Didymocentrus krausi, a small fossorial scorpion that inhabits the Tropical Dry Forest of Central ...
Neutralization of myotoxic phospholipases A2 from the venom of the snake Bothrops asper by monoclonal antibodies
(1992)
The neutralization of two myotoxic phospholipases A2 from the venom of Bothrops asper, myotoxins I and II, by two murine monoclonal antibodies is reported. The monoclonal antibodies, MAb-3 and Mab-4, recognize different ...

Venomics of the scorpion Tityus ocelote (Scorpiones, Buthidae): Understanding venom evolution in the subgenus Archaeotityus
(2022)
The subgenus Tityus (Archaeotityus) includes small variegated species considered until recently, a basal group within Tityus, one of the most diverse and medically relevant genera of scorpions in the New World. Archaeotityus ...
Skeletal muscle degeneration and regeneration after injection of bothropstoxin-II, a phospholipase A2 isolated from the venom of the snake Bothrops jararacussu
(1991)
A myotoxic phospholipase A2, named bothropstoxin II (BthTX-II), was isolated from the venom of the South American snake Bothrops jararacussu and the pathogenesis of myonecrosis induced by this toxin was studied in mice. ...
High Efficacy of Therapeutic Equine Hyperimmune Antibodies Against SARS-CoV-2 Variants of Concern
(2021)
SARS-CoV-2 variants of concern show reduced neutralization by vaccine-induced and
therapeutic monoclonal antibodies; therefore, treatment alternatives are needed. We
tested therapeutic equine polyclonal antibodies (pAbs) ...
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 ...
