Producción de enzimas ligninolíticas durante la degradación del herbicida paraquat por hongos de la pudrición blanca

Rev. argent. microbiol; 49 (2), 2017
El paraquat es un herbicida utilizado ampliamente en la agricultura. Debido a su gran distribución y uso inadecuado, representa un problema grave de contaminación del suelo y el agua. Se ha encontrado que los hongos de la podredumbre blanca son capaces de degradar compuestos contaminantes que poseen es...

Differential expression on mitochondrial tryparedoxin peroxidase (mTcTXNPx) in Trypanosoma cruzi after ferrocenyl diamine hydrochlorides treatments

Braz. j. infect. dis; 21 (2), 2017
Abstract Resistance to benznidazole in certain strains of Trypanosoma cruzi may be caused by the increased production of enzymes that act on the oxidative metabolism, such as mitochondrial tryparedoxin peroxidase which catalyses the reduction of peroxides. This work presents cytotoxicity assays performed...

In vitro antioxidant properties, free radicals scavenging activities of extracts and polyphenol composition of a non-timber forest product used as spice: Monodora myristica

Biol. Res; 48 (), 2015
BACKGROUND: Excessive production of free radicals causes direct damage to biological molecules such as DNA, proteins, lipids, carbohydrates leading to tumor development and progression. Natural antioxidant molecules from phytochemicals of plant origin may directly inhibit either their production or limit...

Enhancement of ligninolytic enzyme activities in a Trametes maxima-Paecilomyces carneus co-culture: Key factors revealed after screening using a Plackett-Burman experimental design

Electron. j. biotechnol; 17 (3), 2014
Background In the industrial biotechnology, ligninolytic enzymes are produced by single fungal strains. Experimental evidence suggests that co-culture of ligninolytic fungi and filamentous microfungi results in an increase laccase activity. In this topic, only the ascomycete Trichoderma spp. has been stu...

Clinical evaluation with self-sequential longitudinal reference intervals: pregnancy outcome and neonatal thyroid stimulating hormone level associated with maternal thyroid diseases

West Indian med. j; 62 (1), 2013
OBJECTIVE: We attempted to evaluate maternal thyroid function in a new self-sequential longitudinal reference interval (SLRI) which we established recently. By this method, we analysed the correlation between pregnancy outcome, neonatal thyroid stimulating hormone (TSH) level and maternal thyroid disease...

Utilização de 2-metil-1-propenilbenzoato na determinação quimiluminescente de esterases de monócitos, butirilcolinesterase sérica e de conjugados de peroxidase

Recentemente, desenvolvemos um novo ensaio quimiluminescente disparado por hidrolases sobre 2-metil-1-propenilbenzoato (MPB) na presença de `H IND. 2ï`O IND. 2ï e peroxidase de raiz forte (HRP) (YAVO, et al. (1996) Anal. Biochem., v. 234, p. 215-220). A hidrólise de MPB, catalisada por esterase, orig...

Aplicación de inmunoperoxidasa en lesiones cervicales uterinas por virus papilloma humano (UPH)

Este trabajo fue realizado en una población de 7.200 pacientes de la consulta diaria de la Unidad de Ginecología, Reproducción y Salud Integral, de Valencia, las cuales asistieron en un período de dos años, entre julio de 1982 a julio de 1985. Se seleccionaron 55 pacientes con manifestaciones clíni...
