Improved biomass and protein production in solid-state cultures of an Aspergillus sojae strain harboring the Vitreoscilla hemoglobin
(2015-07-30)The biotechnological value of Aspergillus sojae ATCC 20235 (A. sojae) for production of pectinases in solidstate fermentation (SSF) has been demonstrated recently. However, a common drawback of fungal solid-state cultures ... -
Improving antivenom availability and accessibility: Science, technology, and beyond
(2012-09-15)Snakebite envenomings constitute a serious and neglected public health problem. Despite the fact that effective treatment exists, i.e. administration of animal-derived antivenoms, the availability and accessibility of these ... -
In vitro activity of BaH1, the main hemorrhagic toxin of Bothrops asper snake venom on bovine endothelial cells
(1995-10)Incubation of BaH1, the main hemorrhagic toxin purified from the venom of Bothrops asper, with endothelial cells caused the appearance of spaces among the cells. This effect became more noticeable with increasing hemorrhagin ... -
In vitro Characterization of Anti-SARS-CoV-2 Intravenous Immunoglobulins (IVIg) Produced From Plasma of Donors Immunized With the BNT162b2 Vaccine and Its Comparison With a Similar Formulation Produced From Plasma of COVID-19 Convalescent Donors
(2022)Despite vaccines are the main strategy to control the ongoing global COVID-19 pandemic, their effectiveness could not be enough for individuals with immunosuppression. In these cases, as well as in patients with ... -
In vitro discovery of a human monoclonal antibody that neutralizes lethality of cobra snake venom.
(2022)The monocled cobra (Naja kaouthia) is among the most feared snakes in Southeast Asia due to its toxicity, which is predominantly derived from long-chain α-neurotoxins. The only specific treatment for snakebite envenoming ... -
In vitro effects of environmental isolates of Acanthamoeba T4 and T5 over human erythrocytes and platelets
(2020-01-21)Free-living amoebae of the genus Acanthamoeba have been associated with keratitis and encephalitis. Some factors related to their pathogenic potential have been described, including the release of hydrolytic enzymes, and ... -
In Vitro Inhibition of Zika Virus Replication with Amantadine and Rimantadine Hydrochlorides
(2021-09-15)Zika virus (ZIKV) is a mosquito-borne flavivirus in which human infection became relevant during recent outbreaks in Latin America due to its unrecognized association with fetal neurological disorders. Currently, there ... -
In vitro multiplication of Toxoplasma gondii and Trypanosoma cruzi in mouse, rat and hamster astrocytes
(2003-08-01)The infection and multiplication of Toxoplasma gondii and Trypanosoma cruzi were compared in primary cultures of white rat, mouse and hamster astrocytes. These cells were cultured on cover slides and infected with T. gondii ... -
In vivo neutralization of Myotoxin II, a phospholipase A2 homolog from Bothrops asper venom, using peptides discovered via phage display technology
(2022)Many snake venom toxins cause local tissue damage in prey and victims, which constitutes an important pathology that is challenging to treat with existing antivenoms. One of the notorious toxins that causes such effects ... -
In vivo neutralization of the dendrotoxin-mediated neurotoxicity of black mamba venom by oligoclonal human IgG monoclonal antibodies
(2018)The black mamba (Dendroaspis polylepis) is one of the most feared snake species of the African savanna. It has a potent, fast-acting neurotoxic venom comprised of dendrotoxins and α-neurotoxins associated with high ... -
In vivo treatment with varespladib, a phospholipase A2 inhibitor, prevents the peripheral neurotoxicity and systemic disorders induced by Micrurus corallinus (coralsnake) venom in rats
(2022-03)In this study, we investigated the action of varespladib (VPL) alone or in combination with a coral snake antivenom (CAV) on the local and systemic effects induced by Micrurus corallinus venom in rats. Adult male Wistar ... -
Incidencia de diabetes tipo 2 en un área urbano marginal de Costa Rica
(Acta Médica Costarricense 50(1) p 29-34, 2008-01)Justification and Objective: Diabetes is now a global epidemic. Once thought to be a disease primarily affecting developed nations, diabetes is growing rapidly and exponentially in developing nations, seriously impacting ... -
Increased Infectivity of Staphylococcus aureus in an Experimental Model of Snake Venom–Induced Tissue Damage
(2007-09-01)Soft-tissue infection is commonly found in patients bitten by Latin American Bothrops snakes. Staphylococcus aureus, which is not present in the mouth of the snake, is frequently isolated from these infections. The effects ... -
Increments in cytokines and matrix metalloproteinases in skeletal muscle after injection of tissue-damaging toxins from the venom of the snake Bothrops asper
(2002)Envenomations by the snake Bothrops asper are characterized by prominent local tissue damage (i.e. myonecrosis), blistering, hemorrhage and edema. Various phospholipases A2 and metalloproteinases that induce local pathological ... -
Increments in serum cytokine and nitric oxide levels in mice injected with Bothrops asper and Bothrops jararaca snake venoms
(2000-09)Changes in serum levels of several cytokines and nitric oxide were studied in BALB/c mice injected intraperitoneally with one median lethal dose (LD(50)) of the venoms of Bothrops asper and Bothrops jararaca, two of the ... -
Individual expression patterns of myotoxin isoforms in the venom of the snake Bothrops Asper.
