O uso de proteinados e percepção de efeitos adversos por acadêmicos do Curso de Educação Física

Objetivo: analisar o uso de proteinados por um grupo de acadêmicos do Curso de Educação Física de uma instituição de ensino Superior e a percepção dos participantes quanto aos possíveis efeitos adversos. Métodos: aplicou-se um questionário semiestruturado, com a colaboração de 90 acadêmicos...

Protein structure of the venom in nine species of snake: from bio-compounds to possible healing agents

Braz. j. med. biol. res; 53 (1), 2020
Due to its various structures in bio-compounds, snake venom is the indisputable result of evolutionary stages of molecules with an increasingly complex structure, high specificity, and of great importance for medicine because of their potential. The present study proposed an underpinning examination of v...

The role of high mobility proteins (HMGB1) in systemic lupus erythematosus

Rev. colomb. reumatol; 27 (1), 2020
ABSTRACT Introduction: The high mobility group box 1 proteins (HMGB1) are non-histone nuclear proteins reported to be present at high levels in some autoimmune diseases, such as systemic lupus erythematosus (SLE). Likewise, in contrast to healthy individuals, patients with SLE have a higher prevalence ...

Protein Profiles of Individuals with Erosive Tooth Wear

Abstract Objective: To determine if protein profiles identified in saliva could be used to determine risk and severity of erosive tooth wear. Material and Methods: Three types of saliva sampling were performed to obtain saliva from 34 18-year old individuals that received regular dental check-ups, alon...

Comparison of protein profiles of the pellicle, gingival crevicular fluid, and saliva: possible origin of pellicle proteins

Biol. Res; 53 (), 2020
BACKGROUND: The pellicle, the acellular organic material deposited on the surface of tooth enamel, has been thought to be derived from saliva. In this study, protein compositions of the pellicle, gingival crevicular fluid, and saliva collected from healthy adults were compared to elucidate the origin of ...

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...

Influence of lipids and proteins amounts and pH values on the inhibitory effects of Origanum vulgare L. essential oil against Escherichia coli and Salmonella Typhimurium

Origanum vulgare L. (OVEO) essential oil has been considered a candidate antimicrobial for use in food conservation systems. However, studies on the influence of concomitant variations of different food components or physicochemical parameters on the antibacterial properties of OVEO are scarce. This stud...

An in silico investigation of phytochemicals as potential inhibitors against non-structural protein 1 from dengue virus 4

Dengue fever has emerged as a big threat to human health since the last decade owing to high morbidity with considerable mortalities. The proposed study aims at the in silico investigation of the inhibitory action against DENV4-NS1 of phytochemicals from two local medicinal plants of Pakistan. Non-Struct...

The insertion of bioactive peptides at the C-terminal end of an 11S globulin changes the structural stability and improves the antihypertensive activity

BACKGROUND: The 11S globulin from amaranth is the most abundant storage protein in mature seeds and is well recognized for its nutritional value. We used this globulin to engineer a new protein by adding a four valinetyrosine antihypertensive peptide at its C-terminal end to improve its functionality. Th...

EQA-based evaluation of metrological traceability of clinical chemistry test results in Argentina

Equivalence of results among laboratories is a major mission for medical laboratories. In the Netherlands, medical laboratories only use homogenous, commercial for general chemistry analytes, whereas in Argentina heterogenous, home brew test applications are common. The effect of this practice difference...
