Development and validation of analytical method for sulfonamide residues in egg...

Liquid chromatography- electrospray ionization - tandem mass spectrometry (LC-ESI-MS/MS) was used to simultaneous determination of ten sulfonamide (SAs) residues (sulfacetamide, sulfathiazole, sulfamerazine, sulfamethazine, sulfamethoxypyridazine, sulfamethizole, sulfachloropyridazine, sulfamethoxazole, sulfadimethoxine and sulfaquinoxaline) in eggs. Samples were extracted with acetonitrile and the supernatants...

Evaluation and characterization of antioxidant and antigenotoxic properties of ...

Propolis is a substance produced by bees (Apis mellifera L.) after harvest of buds and bark of plants and by subsequent mixing with the salivary enzyme β-glucosidase. Bees use propolis in their combs as protection, to repair damage, to build aseptic locals for the eggs of the queen, and also as a thermal insulator. The composition of propolis varies geographically, with the available flora, the time of collecti...

Propolis is a substance produced by bees (Apis mellifera L.), after harvesting exsudates of plant buds and barks, and subsequent mixing with the salivary enzyme β-glucosidase. Bees use propolis in their combs as protection, to repair damage, to build aseptic locals for the eggs of the queen, and also as a thermal insulator. The composition of propolis varies geographically, with the available flora, the time of...

Herbicidal properties of portuguese propolis samples

Propolis is a natural product made by honeybees (Apis mellifera L.) with important physical and biological protective functions, being used to maintain hive integrity, as well as adequate thermal and sanitary conditions. It is a complex mixture made essentially from collected plant exudates, being composed of waxes, resins, balsams, pollen, essential oils, and other organic and mineral compounds. It has a high ...

Dissertação de mestrado em Biotecnologia e Bio-empreendedorismo em Plantas Aromáticas e Medicinais ; O própolis é uma substância produzida pelas abelhas (Apis mellifera L.) após a colheita de brotos e cascas de plantas e pela mistura posterior com a enzima salivar β-glicosidase. As abelhas utilizam o própolis nos seus favos como proteção, para reparar danos, construir locais assépticos para os ovos da rainha, ...

Eletroneuromiografia e potenciais evocados somatossensitivos na mielopatia pelo...

Tivemos como objetivo investigar por eletroneuromiografia (ENMG) e potenciais evocados somatossensitivos a possibilidade de acometimento do nervo periférico na mielopatia pelo HTLV-I (HAM), correlacionando os achados com os parâmetos clínicos e com a síntese intratecal de anticorpos anti HTLV-I. Os pacientes tinham sorologia negativa para HIV e apresentaram VDRL negativo. Outras causas para mielopatia ou neurop...

Electroneuromyography and neuromuscular findings in 16 primary hypothyroidism p...

There has been few reports on electroneuromyography (ENMG) changes in hypothyroidism. The objectives of the present study were to investigate the frequency of ENMG abnormalities in hypothyroidism and correlate them with neurological signs and symptoms and muscle enzyme levels; and to compare latency, amplitude and nerve conduction velocity from selected nerves with controls. Sixteen patients suffering from prim...
