Detection of proteins antigenically-related to Bothrops asper myotoxin in crotaline snake venoms
(1987)
The presence of components antigenically related to Bothrops asper myotoxin was investigated by Western blotting and immunoelectrophoretic techniques. B. asper myotoxin is a non-glycosylated monomeric phospholipase A with ...
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 ...
Phospholipases A2: Unveiling the secrets of a functionally versatile group of snake venom toxins
(2013-02)
Phospholipases A2 (PLA2s) are abundant components of snake venoms, where they play toxic and digestive roles. Despite having a similar three-dimensional structure, venom PLA2s exert an amazing variety of toxic and ...
A Call for Incorporating Social Research in the Global Struggle against Snakebite
(2015-09-17)
In Africa, Asia, Latin America, and parts of Oceania, envenoming after snakebite is a serious
public health problem. Conservative data suggest that between 1.2 and 5.5 million people
suffer snakebites every year, resulting ...
Skin Pathology Induced by Snake Venom Metalloproteinase: Acute Damage, Revascularization, and Re-epithelization in a Mouse Ear Model
(2008-10)
Viperid snakebite envenomation induces blistering and dermonecrosis. The pathological alterations induced by a snake venom metalloproteinase in the skin were investigated in a mouse ear model. Metalloproteinase BaP1, from ...
Inhibition by CaNa2EDTA of local tissue damage induced by Bothrops asper (terciopelo) venom: Application in horse immunization for antivenom production
(1998-03-26)
The ability of the chelating agent CaNa2EDTA to inhibit local tissue damage induced by Bothrops asper venom was studied in mice and in horses used for polyvalent (Crotalinae) antivenom production. CaNa2EDTA was devoid of ...
A phospholipase A2 from Bothrops asper snake venom activates neutrophils in culture: Expression of cyclooxygenase-2 and PGE2 biosynthesis
(2011-02)
In this study, the production of prostaglandin E2 (PGE2) and up-regulation in cyclooxygenase (COX) pathway induced by a phospholipase A2 (PLA2), myotoxin-III (MT-III), purified from Bothrops asper snake venom, in isolated ...
Omics Meets Biology: Application to the Design and Preclinical Assessment of Antivenoms
(Toxins vol.6:3388-3405, 2014-12-15)
Snakebite envenoming represents a neglected tropical disease that has a heavy public health impact worldwide, mostly affecting poor people involved in agricultural activities in Africa, Asia, Latin America and Oceania. A ...
Preclinical evaluation of the efficacy of antivenoms for snakebite envenoming: State-of-the-art and challenges ahead
(2017-05)
Animal-derived antivenoms constitute the mainstay in the therapy of snakebite envenoming. The efficacy of antivenoms to neutralize toxicity of medically-relevant snake venoms has to be demonstrated through meticulous ...
Role of nitric oxide in the local and systemic pathophysiological effects induced by Bothrops asper snake venom in mice
(2006)
Objective
To assess the role of nitric oxide in the most relevant local and systemic manifestations in mice injected with the venom of the snake Bothrops asper. Mice were pretreated with nitric oxide synthase inhibitors, ...
