Opis:
Atypical but real practical problems relating to the dynamics of block-type foundations for machines are considered using the deterministic approach and assuming that the determined parameters are random variables. A foundation model in the form of an undeformable solid on which another undeformable solid modelling a machine is mounted via viscoelastic constraints was adopted. The dynamic load was defined by a harmonically varying signal and by a series of short duration signals. The vibration of the system was investigated for the case when stratified ground (groundwater) occurred within the side backfill was present. Calculation results illustrating the theoretical analyses are presented.

Opis:
Mycobacterium avium ssp. paratuberculosis (MAP) is the cause of chronic gastroenteritis in cattle called the Johne’s disease (JD). The disease causes significant economic losses in cattle production. MAP is also supposed to be involved in the Crohn’s disease and inflammatory bowel disease (IBD) in people. The detection of the cattle infection based on investigations of milk samples and evaluation of the capacity of the methods used to detect the disease was the objective of the present study. Following methods were applied for milk samples testing: detection of MAP in bacterial culture, detection of the specific IS-900 fragment of MAP in the genetic material isolated directly and detection of MAP antibodies. The results obtained were compared with the “golden standard” results, i.e. the isolation of MAP from the faeces. PQStat-the program for diagnostic reliability estimation, was used for evaluation of the sensitivity, specificity and predictive value. The method based on detection of the specific IS-900 fragment of MAP in the genetic material isolated directly from milk samples was found to possess the highest sensitivity. Detection of anti-MAP antibodies on the other hand showed the lowest sensitivity. The method of detecting anti-MAP antibodies in milk was the most specific while detection of the IS-900 fragment in the genetic material was the least specific method. These results obtained may serve as a guide to choose the most appropriate method for diagnosis of MAP infections by milk sample testing.

Opis:
Leptin is a polypeptide hormone produced predominantly in adipocytes. It has been found to be implicated in the regulation of satiety and energy homeostasis. A role for leptin in reproduction was later suggested by findings that this hormone may be involved in the regulation of the hypothalamic- pituitary-gonadal axis via endocrine, paracrine and/or autocrine pathways. The objective of the study was to investigate the ontogeny of the long isoform of leptin receptor (OB-Rb) gene in porcine ovarian follicles. The expression of OB-Rb gene was detected in porcine primordial, primary, secondary and antral follicles by in situ hybridization. In summary, our data suggest that leptin might have a direct effect on porcine follicles and plays an important role in the follicular development.
