Ovarian carcinoma immunoreactive antigen-like protein 2 (OCIAD2) is a novel complex III-specific assembly factor in mitochondria.

Assembly of the dimeric complex III (CIII) in the mitochondrial inner membrane is an intricate process in which several accessory proteins are involved as assembly factors. Despite numerous studies, this process has yet to be fully understood. Here we report the identification of human OCIAD2 (ovarian carcinoma immunoreactive antigen-like protein 2) as an assembly factor for CIII.

Specificity of mass spectrometry (MALDI-TOF) in the diagnosis of Babesia canis regarding to other canine vector-borne diseases.

Unlabelled: The canine vector-borne diseases (CVBD) is a term, which describes a range of infectious or/and parasitic diseases whose etiological agents are transmitted by vectors. CVBD are becoming more widely in the world in relation to global warming and the increasing number of infected vectors. The aim of this study was to assess rapid mass spectrometry (MS) - based proteomics analyses for diagnosis of Babesia canis, Anaplasma phagocytophilum and Borrelia burgdorferi infections in dogs.

Prevalence and antibiotic resistance of Enterococcus strains isolated from poultry.

The aim of this study was to evaluate the frequency of occurrence of bacteria of the genus Enterococcus in poultry, to identify them by means of matrixassisted laser desorption/ionisation time-of-flight mass spectrometry (MALDITOF MS), and to analyse the antimicrobial susceptibility of the isolated strains to the drugs most frequently used in poultry. The material for the bacteriological tests was obtained mainly from the heart (97%) of the birds investigated. Of a total of 2,970 samples tested, 911 (30.

Dog Tear Film Proteome In-Depth Analysis.

In this study, mass spectrometry was used to explore the canine tear proteome. Tear samples were obtained from six healthy dogs, and one-dimensional sodium dodecyl sulphate polyacrylamide gel electrophoresis (1D SDS-PAGE) was used as a first step to separate intact proteins into 17 bands. Each fraction was then trypsin digested and analysed by matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry (MALDI-TOF-MS/MS) to characterize the protein components in each fraction.

Modified 16S-23S rRNA intergenic region restriction endonuclease analysis for species identification of Enterococcus strains isolated from pigs, compared with identification using classical methods and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Fast and reliable identification of bacteria to at least the species level is currently the basis for correct diagnosis and appropriate treatment of infections. This is particularly important in the case of bacteria of the genus Enterococcus, whose resistance profile is often correlated with their species (e.g.

Application the mass spectrometry MALDI-TOF technique for detection of Babesia canis canis infection in dogs.

The aim of this study was to use rapid mass spectrometry (MS)-based proteomics analyses for diagnosis of Babesia canis canis infections in dogs. The study was conducted on two groups of dogs--healthy dogs and dogs infected with B. canis canis which demonstrated symptoms of babesiosis.

Epicutaneous immunization with hapten-conjugated protein antigen alleviates contact sensitivity mediated by three different types of effector cells.

Background: Allergic contact dermatitis (ACD) is a common clinical condition in industrialized countries and often causes occupational diseases. Animal model of contact sensitivity (CS) is commonly used to study ACD in mice and can be induced by skin application of haptens. It has been previously shown that CS is mediated by CD4(+) or CD(8+) T effector cells.

[TNFalpha and sVCAM plasma levels during standard exercise test are higher in postmenopausal women with hypercholesterolemia].

Aim: The evaluation of serum ICAM, VCAM, endothelin-1 (Et-1), TNF-alpha and its soluble receptor levels and the secretion of nitric oxide in postmenopausal women with hypercholesterolemia.

Patients: 26 postmenopausal patients who neither received hormonal therapy nor cholesterol lowering treatment. Group A consisted of 16 women with high serum total cholesterol and group B of 10 women with normal cholesterol level.

Myoelectrical activity of small intestine in rats with experimental Parkinson's disease.

Gastrointestinal (GI) motility is governed by enteric nervous system being under surveillance of central and autonomic representation. In Parkinson's disease (PD) GI dysmotility has been attributed in part to peripheral action of neurotoxines. We evaluated the effect of chronic salsolinol administration on intestinal myoelectrical activity (IMA) during fasting and in response to gastric distension (GD) in rats.

[Character of patients with paroxysmal atrial fibrillation].

Paroxysmal atrial fibrillation (PAF) is one of the most frequent cardiac arrhythmias. Our purpose in the current study was the presentation of the main PAF aetiology and the most effective methods of therapy. The study revealed that both coronary artery disease and arterial hypertension are the most frequent reasons of PAF whereas acute physical effort seems to be the main triggering factor.

Mechanisms of intestinal dysmotility in morphine dependence: whether central or peripheral?

Changes of intestinal motility and transit due to morphine administration are attributed to its central and peripheral action, however coexistence of both central and peripheral mu receptors in morphine dependence hasn't been clearly demonstrated so far. Our purpose was the evaluation of the effect of either CNS or ENS mu receptor blockade on intestinal motility in morphine dependent rats. Twenty male rats were subjected to chronic subcutaneous morphine infusions for 72 hrs.

Heart rate variability during incremental cycling exercise in healthy untrained young men.

Background: Linear relationship between the increase of heart rate (HR) and the power output (PO) during sub-maximal exercise is well documented. However the study considering the effect of progressive increase of PO on the parameters of heart rate variability (HRV) remain scarce.

Aim: This study investigated changes of the HRV time and spectral parameters in young, untrained men during incremental cycling exercise.

Effect of hormonal replacement therapy on autonomic regulation of the heart.

Background: Increased incidence of cardiovascular diseases frequently reported in postmenopausal women may follow disturbed activity of cardiac autonomic nervous system (cANS). Our purpose was to evaluate the influence of continuous combined hormonal replacement therapy (ccHRT) on cANS reflected by parameters of heart rate variability (HRV).

Method: Thirty four healthy postmenopausal women aged 56+/-6 years (7+/-4 years after last menorrhoea) were divided into 2 equal groups--women receiving ccHRT (serum estradiol--81+/-75 ng/l, FSH--45+/-27 IU/l) and control group (serum estradiol--31+/-45 ng/l, FSH--74+/-32 IU/l).

Circadian heart rate variability in patients with primary arterial hypertension.

Introduction: Abnormalities of autonomic nervous system function (ANS) exist in patients with hypertension and have been considered as one of the important factors in developing of essential hypertension. However the information about the effect of antihypertensive treatment (angiotensin-converting enzyme inhibitors--ACEI) on cardiac ANS activity is scarce. The main aim of our study was to evaluate circadian heart rate variability changes in primary hypertension treated with ACE inhibitors.
