Proteomic profile of the venom of three dark-colored Tityus (Scorpiones: Buthidae) from the tropical rainforests of Costa Rica
(2023)
Objective: We aimed to elucidate the potential differences in the venom peptide sequences of three Tityus species
from Costa Rican rainforests: T. jaimei, T. championi and T. dedoslargos, compared to T. cf. asthenes ...
Venomics of the poorly studied hognosed pitvipers Porthidium arcosae and Porthidium volcanicum
(2021)
We report the first proteomics analyses of the venoms of two poorly studied snakes, the Manabi hognosed pitviper Porthidium arcosae endemic to the western coastal province of Manabí (Ecuador), and the Costa Rican hognosed ...
Proteomic and toxicological analysis of the venom of Micrurus yatesi and its neutralization by an antivenom
(2022)
Coralsnakes belong to the family Elapidae and possess venoms which are lethal to humans and can be grouped based on the predominance of either three finger toxins (3FTxs) or phospholipases A2 (PLA2s). A proteomic and ...
Gene Expression Dynamics Induced by Ciprofloxacin and Loss of LexA Function in Pseudomonas aeruginosa PAO1 Using Data Mining and Network Analysis
(2018)
Pseudomonas aeruginosa is an opportunistic
pathogen that causes a variety of infections in humans and
frequently develops mechanisms of resistance to antibiotics, which
makes its treatment difficult. In this study we ...
Influencia del uso del suelo en la calidad del agua en la subcuenca del río Jabonal, Costa Rica
Influence of the land use in the quality of the water in the subwatershed of the river Jabonal, Costa Rica.
(2006-08)
La subcuenca del río Jabonal, Costa Rica, se
caracteriza por el predominio de extensas áreas
dedicadas a la producción ganadera. Se seleccionaron ocho microcuencas y se evaluó la calidad
del agua a través de análisis ...
Effects of oxytetracycline on the performance and activity of biomixtures: Removal of herbicides and mineralization of chlorpyrifos
(2017)
Biopurification systems (BPS) are design to remove pesticides from agricultural wastewater. This work assays for the first time the potential effect of an antibiotic of agricultural use (oxytetracycline, OTC) on the ...
Biodegradation of sulfamethazine by Trametes versicolor: Removal from sewage sludge and identification of intermediate products by UPLC–QqTOF-MS
(2011-11-15)
Degradation of the sulfonamide sulfamethazine (SMZ) by the white-rot fungus Trametes versicolor was assessed.
Elimination was achieved to nearly undetectable levels after 20 h in liquid medium when SMZ was added at
9 mg ...
Pathological changes induced by BaH1, a hemorrhagic proteinase isolated from Bothrops asper (Terciopelo) snake venom, on mouse capillary blood vessels
(1994-08)
The pathological changes induced in capillaries by BaH1, a hemorrhagic metalloproteinase isolated from the venom of Bothrops asper, were studied after i.m. injection in mouse gastrocnemius. Hemorrhage was observed ...
Inhibitory effects of Piper umbellatum and Piper peltatum extracts towards myotoxic phospholipases A2 from Bothrops snake venoms: isolation of 4-nerolidylcatechol as active principle
(2005)
Phospholipases A2 (PLA2) are important constituents of snake venoms, being responsible for several of their toxic actions.
Extracts from plants used in folk medicine were screened for inhibition of the enzymatic activity ...
Degradation of naproxen and carbamazepine in spiked sludge by slurry and solid-phase Trametes versicolor systems
(2010-04)
rowth and activity of the white-rot fungus Trametes versicolor on sewage sludge were assessed in bio slurry and solid-phase systems. Bioslurry cultures with different loads of sludge (10%, 25% and 38%, w/v)
were performed. ...
