The effect of thymol on acetylcholine-induced contractions of the rat ileum and uterus under conditions.

Thyme ( L.) is a well-known medicinal plant, the aerial parts of which have long been used internally or externally as a traditional remedy for various diseases. Thyme essential oils have important pharmaceutical applications and are regularly used in the pharmaceutical, food and cosmetic industries.

Insect Protein-Based Diet as Potential Risk of Allergy in Dogs.

Before insects can be used widely as an alternative source of dietary protein, their allerginicity should be investigated. Therefore, the aim of our study was to assess the potential adverse reactions of the immune system of dogs against proteins. Dogs sensitised to storage mites and were included.

Proteomic Analysis of Fresh and Liquid-Stored Boar Spermatozoa.

In this study comparative proteomics was used to define changes in the expression of the spermatozoa proteins during liquid storage. Semen from eight boars was analyzed on the day of collection and after liquid preservation at 15-17 °C for three days. Sperm parameters (concentration, motility, morphology, vitality) and percentage of non-capacitated and acrosomal-reacted spermatozoa were determined.

Dialysis of the goat semen and its effect on the quality of frozen/thawed spermatozoa processed in the presence of egg yolk.

The aim of the present study was to analyze the effect of dialysis on the quality of frozen/thawed buck semen. Ejaculates (n = 15) from three Saanen bucks were divided into three experimental groups. Semen in Group Ce (centrifugation) was processed by standard method and washed two times at 1.

Serum protein profiles, circulating immune complexes and proteinuria in dogs naturally infected with Anaplasma phagocytophilum.

Alterations in serum protein profile, presence of circulating immune complexes (CIC) and proteinuria were investigated in a large group of dogs naturally infected with the Anaplasma phagocytophilum bacterium. Our aim was to evaluate the presence of hypergammaglobulinaemia, CIC and proteinuria as a possible result of an immune-mediated disease following infection by or exposure to A. phagocytophilum.

Retrospective study of bull semen quality - possible correlation with pesticide use?

Decline in semen quality in humans and increased incidence of male reproductive problems could be caused by different factors, including pesticides that could mimic or block the action of endogenous hormones. If the decline in semen quality is real, and environmental chemicals are at least partially responsible for this decline, similar changes should be observed in animals that live in close connection with humans and are exposed to similar levels of pollutants. In the present study, the semen quality of bulls in the last 30 years was examined with respect to the year of birth.

Effects of synthetic analogues of poly-APS on contractile response of porcine coronary arteries.

APS12-2 and APS3 are synthetic analogues of polymeric alkylpyridinium salts (poly-APS) isolated from the marine sponge Reniera sarai. The aim of the present study was to determine the possible direct contractile effects of these two synthetic molecules on coronary arteries, in order partly to explain hemodynamic and cardiotoxic effects of APS12-2 previously observed in in vivo studies and to reveal possible adverse effects on the organism in the case of their clinical use. In contrast to APS3, APS12-2 caused a concentration-dependent vascular smooth muscle contraction of isolated porcine coronary ring preparations in a concentration-range from 1.

Dermatophyte Trichophyton mentagrophytes Produces Cysteine Protease Inhibitor.

The protein inhibitor of cysteine proteases was isolated from an important zoophilic dermatophyte species Trichophyton mentagrophytes (T. mentagrophytes) and partially characterized. The isolation process involved affinity chromatography, followed by ion-exchange chromatography and reverse phase high performance liquid chromatography.
