Fluorescence Imaging Approaches in Flavivirus Research
(2021-10-01)The genus Flavivirus within the family Flaviviridae contains many arthropod-borne infectious agents of medical relevance like dengue virus (DENV), Zika virus (ZIKV), and West Nile virus (WNV), among others, that cause ... -
Focal Philophthalmus gralli infection possibly persists in Melanoides tuberculata over two years following the definitive hosts' removal
(2014)Philophthalmosis is a zoonotic disease associated largely with the spread of the invasive freshwater snail Melanoides tuberculata, serving as an intermediate host. Here we examined Philophthalmus gralli focal fenced infection ... -
Frecuencias de grupos sanguíneos ABO, Rh y Kell en donantes de sangre y pacientes de los bancos de sangre de los hospitales San Juan de Dios, Calderón Guardia y México entre los años 2009 y 2018
(2023-08-10)Los sistemas sanguíneos ABO, Rh y Kell son los más relevantes desde el punto de vista clínico por su inmunogenicidad y ser los principales causantes de reacciones hemolíticas. Mediante este estudio estimamos las frecuencias ... -
Freeze-dried snake antivenoms formulated with sorbitol, sucrose or mannitol: Comparison of their stability in an accelerated test
(2014-11)Freeze-drying is used to improve the long term stability of pharmaceutical proteins. Sugars and polyols have been successfully used in the stabilization of proteins. However, their use in the development of freeze-dried ... -
From Fangs to Pharmacology: The Future of Snakebite Envenoming Therapy
(2016)The snake is the symbol of medicine due to its association with Asclepius, the Greek God of medicine, and so with good reasons. More than 725 species of venomous snakes have toxins specifically evolved to exert potent ... -
Functional analysis of DM64, an antimyotoxic protein with immunoglobulin-like structure from Didelphis marsupialis serum
(2002-12-11)Bothrops snake venoms are known to induce local tissue damage such as hemorrhage and myonecrosis. The opossum Didelphis marsupialis is resistant to these snake venoms and has natural venom inhibitors in its plasma. The aim ... -
Functional, proteomic and transcriptomic characterization of the venom from Micrurus browni browni: identification of the first lethal multimeric neurotoxin in coral snake venom
(2020)Proteomic characterization of Micrurus browni browni venom showed approximately 41 components belonging to 9 protein families, mainly phospholipases A2 (PLA2s) and three-finger toxins (3FTxs). Venom gland transcriptome ... -
Fungal contamination of stored automobile-fuels in a tropical environment
(2010-10)Because of the lack of reports, the base levels of microbial contamination on stored fuels are unknown in tropical regions and it is unclear whether these levels have some influence on fuel quality parameters. Therefore, ... -
Fungal-Mediated Degradation of Emerging Pollutants in Sewage Sludge
(2012-01-01)This chapter summarizes the novel approaches employed for the removal of emerging pollutants from sludge by means of fungal processes. The first part of the chapter introduces the potential application of fungi in ... -
Fungicidal activity of a phospholipase A2-derived synthetic peptide variant against Candida albicans
(2007-09)pEM-2, a 13-mer synthetic peptide variant derived from myotoxin II, a phospholipase A2 homologue present in Bothrops asper snake venom, has shown potent bactericidal activity in previous studies due to the combination of ... -
Fur mite, Listrocarpus alouattae Fain (Acari: Atopomelidae), from Alouatta palliata Gray (Primates: Cebidae) in Costa Rica
(2002)Se presentan resultados preliminares de un estudio sobre ectoparásitos de monos de Costa Rica. Se evaluaron 36 monos aulladores (Alouatta palliata Gray, 1849) y 3 monos capuchinos (Cebus capucinus Linnaeus, 1758) provenientes ... -
Gene expression analyses of gingival tissue of patients with periodontitis using public transcriptomic data
(2022-11)Abstract—Periodontal disease (PD) is a multifactorial and chronic condition of infection and inflammation of the gingival tissue. However, many of the biological and molecular mechanisms regarding the development of this ... -
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 ... -
