Preparation and in vitro release profiling of PLGA microspheres containing BSA as a model protein

Conventional drug formulations are incapable of adequate delivery of proteins and peptides for therapeutic purposes. As these molecules have very short biological half-life, multiple dosing is required to achieve the desirable therapeutic effects. Microspheres are able to encapsulate proteins and peptide...

Mimosine increases the expressions of tyrosine phosphorylated protein in mouse seminal vesicles

Int. j. morphol; 37 (4), 2019
Acute effect of purified mimosine (MiMo) extracted from Leucaena leucocephala on testicular histopathology has been documented with seminal vesicle (SV) atrophy. Since protein phosphorylation and seminal secretions play important roles in sperm physiology, this study aimed to study the alteration of subs...

Purification and biochemical characterization of a novel thermophilic exo-β-1, 3-glucanase from the thermophile biomass-degrading fungus Thielavia terrestris Co3Bag1

Background: The aim of this work was to purify and characterize exo-β-1,3-glucanase, namely, TtBgnA, from the thermophilic fungus Thielavia terrestris Co3Bag1 and to identify the purified enzyme. Results: The thermophilic biomass-degrading fungus T. terrestris Co3Bag1 displayed β-1,3-glucanase activity...

Transferrina como marcador de maturação pulmonar em cordeiros nascidos a termo ou prematuros

O objetivo do estudo foi procurar proteínas de fase aguda que possam indicar sinais de maturação no neonato prematuro, por meio da quantificação sérica delas. Identificou-se a imunoglobulina A, a ceruloplasmina, a haptoglobina, a glicoproteína ácida, a transferrina, a albumina e as imunoglobulina...

Aspectos generales del perfil proteómico del Echinococcus granulosus

Int. j. morphol; 37 (2), 2019
La información disponible referente a las características proteómicas del E. granulosus es escasa (no supera los 50 estudios publicados); y nos parece que la identificación proteómica, podría mejorar la comprensión de algunas características bioquímicas e inmunológicas de la Equinococosis Quís...

Differences in protein expression associated with ivermectin resistance in Caenorhabditis elegans

Abstract The indiscriminate administration of synthetic anthelmintics such as ivermectin contributes to the selection of subpopulations capable of resisting the drugs' effects. To understand the mechanisms of ivermectin resistance in Caenorhabditis elegans, this study attempted to identify molecular tar...

Local and systemic effects caused by Crotalus durissus terrificus, Crotalus durissus collilineatus, and Crotalus durissus cascavella snake venoms in swiss mice

Abstract INTRODUCTION: Crotalus envenomations cause serious complications and can be fatal without appropriate treatment. Venom isoforms present and inter/intraspecific variations in the venom composition can result in different symptoms presented by bites by snakes from the same species but from differ...

The alterations of microvasculature, tyrosine phosphorylation, and lipid peroxidation in kidney of rats treated with valproic acid

Int. j. morphol; 37 (1), 2019
SUMMARY: Valproic acid (VPA), an antiepileptic drug, has been demonstrated to damage histology and to change tyrosine phosphorylation patterns with increased oxidative stress in perirenal tissues. This study aimed to investigate the effect of VPA on microstructure, tyrosine phosphorylation, and lipid per...

Diagnostic potential of saliva proteome analysis: a review and guide to clinical practice

Abstract: Proteomic techniques have become popular in medicine and dentistry because of their widespread use in analyzing bodily fluids such as blood, saliva, urine, and gingival crevicular fluids as well as hard tissues such as enamel, dentine, and cementum. This review is a guide to proteomic technique...

Optimización de una técnica de PCR convencional para detección de virus de papiloma humano tipo 16 y 18

El cáncer de cuello uterino es el segundo cáncer femenino más común a nivel mundial. El agente causal es el virus de papiloma humano (VPH). Se han identificado 13 tipos de virus de papiloma humano de alto riesgo oncogénico (VPH-AR), entre los cuales el VPH 16 y VPH 18 son los más frecuentemente det...
