Opis:
The energy and structure of intermolecular hydrogen bonds between water molecule and N-methylamide (NMA) or uracil (U) are discussed on the basis of DFT calculations. Theoretical methods are applied to calculate properties of cis- and trans- NMA complexes with one water molecule. Subsequently, H-bonds in six uracil – water complexes are analyzed. The influence of dispersion interactions and the polar environment on the hydrogen bond energy was analyzed. Results obtained by B3LYP functional with and without Grimme D3 dispersion correction indicate that dispersion interaction plays a significant role in an association process. In addition, the polar solvent reduces the hydrogen bond energy and this reduction is directly proportional to the hydrogen bond energy.

Opis:
NMR spectroscopy belongs to the most versatile techniques used in chemical laboratory for testing the presence of various compounds and elucidation of their structure. In case of more complex natural products chemical intuition and experience applied to analysis of experimental spectra is often supported by theoretical modeling of NMR spectra. However, theoretical predictions should be reliable and the errors associated with the approximations inherent to the existing methods minimized. In this respect, systematic errors, present in calculation of isotropic nuclear magnetic shieldings of the studied molecule need to be minimized. Conversion of nuclear shieldings of the studied molecule to the corresponding chemical shifts is performed by using a calculated reference molecule. This way systematic errors partly cancel and the remaining inaccuracies are efficiently decreased by using a properly selected theoretical reference molecule. In this work we demonstrate the impact of calculation method (selected density functional) and basis set on the predicted isotropic nuclear magnetic shieldings of free benzene and methane in vacuum and in popular solvents using a simple PCM approach. We propose the use of B3LYP, OPBE density functionals and recently designed xOPBE one in combination with Pople’s and Dunning’s basis sets, as well as with the modified STO-3G one. The new, STO(1M)-3G basis set was designed by Leszczyński and co-workers for efficient prediction of 13C NMR parameters in large organic molecules. Two molecules were selected to demonstrate the performance of GIAO B3LYP, OPBE and xOPBE for prediction of 1H and 13C NMR chemical shifts in vacuum and solution in comparison with available experimental data.

Opis:
Objective. This study presents for the first time a case of Hyalomma excavatum hyperparasitism and an analysis of this phenomenon in terms of its potential role in the biology of ticks and epidemiology of tick-borne diseases. Materials and method. Two partially engorged H. excavatum females, one fully engorged female, and 5 males were collected from a naïve rabbit and placed together in a rearing chamber at a temperature of 25 °C and 75% humidity. Results. 3–4 days after tick detachment from the host’s skin, one partially engorged H. excavatum female was observed attached to the idiosoma of the fully engorged conspecific female. Conclusions. This study and observations of other authors confirm that partially engorged ixodid ticks can re-infest the host, and even co-feeding fully engorged ticks in order to collect the blood meal that is indispensable for important physiological processes. However, inefficient feeding of a partially engorged female on another conspecific female may reduce its reproductive performance and disturb the development of eggs and larvae. It seems that parasitism of a tick on another conspecific specimen, when at least one of them is infected by a microorganism, may be a yet poorly explored route of transmission of pathogens or symbionts between the ticks. Initiation of feeding by a hungry or partially engorged tick on a fully engorged specimen is an attempt to obtain food in the drastic conditions of the absence of a target host. Tick hyperparasitism with concurrent pathogen transmission can contribute to the genospecific diversity of pathogens in vectors and hosts.

Opis:
Introduction. The three-host Dermacentor reticulatus tick transmits many pathogens, which are introduced into the host with saliva during feeding. Material and methods. The aim of present study was to analyse the behaviour of males of this species on the host in homogeneous sex groups comprising 15 (group I) and 30 (group II) male specimens and in a mixed group composed of 15 males and 15 females (group III). Results. Although the dynamics of attachment of the males to host skin slightly differed between these three groups, there was no statistically significant difference in the duration of the attachment process. The duration of host attachment of the males in groups I, II, and III at 18 ± 2 °C and 50 ± 2% RH was 2.43 ± 2.46, 7.75 ± 11.85, and 9.07 ± 10.97 days, respectively. After 7–9-day feeding, the male engorgement weight (MEW) was similar, regardless of the size of the group and the presence or absence of females on the host. Tick males ingest a small amount of host blood. The value of MEW in the three groups did not differ statistically from the weight of unengorged specimens. Conclusions. The host feeding behaviour of D. reticulatus males and their effective feeding suggest that they may play a role in transmission of pathogens and non-pathogenic microorganisms with tick saliva during blood meal ingestion. Clinical and laboratory diagnostics of human and animal tick-borne diseases as well as epidemiological studies should consider the possibility of pathogen transmission by males of metastriata ticks, which feed on the host for several days.

Opis:
For the first time in the world literature, the presented study describes oral-anal contact between two sympatric Ixodes ricinus and Dermacentor reticulatus ticks, which are the vectors of many pathogens in Europe. Among the specimens collected in nature, an I. ricinus male was found with the hypostome and chelicerae inserted in the anal aperture of a D. reticulatus female. Given the biological and physiological traits of both species and microorganisms colonising these arthropods, it seems that the interspecific oral-anal contacts between ticks may be an unknown alternative route of transmission of pathogenic and symbiotic microorganisms present in ticks’ alimentary tract, faeces, body surface, and in the haemolymph and organs, taking place when the male’s mouthparts are inserted into the female’s body. The authors suggest that interspecific contacts between ticks in natural conditions can contribute to the spread of some microorganisms among different tick species and their hosts.

Introduction and objective. The great number of pigeon populations in many European cities promotes the spread of the European pigeon tick (Argas reflexus), the bites of which cause local and systemic reactions. The aim was to study the occurrence of A. reflexus in several cities of Upper Silesia, and skin lesions caused by A. reflexus tick bites in humans. Materials and method. The results of investigations carried out in 1995–2002 in five cities located in the Upper Silesian conurbation are presented. Specimens of A. reflexus were collected for one hour in attics and lofts inhabited by these ticks. A history of skin lesions caused by bites was taken from residents who had been infested by A. reflexus. The development of skin lesions was monitored for three months in two individuals who had been bitten several times by these arthropods. Results. In the localities, 987 A. reflexus specimens were collected, including 334 females, 269 males, and 384 various nymphal stages. Within one hour, 38–109 ticks specimens were collected at the study sites. Cases of attacks by unengorged A. reflexus were reported in all the habitats located in the residential buildings; the ticks were also found in residents’ flats and in staircases. Residents who had been repeatedly attacked by European pigeon ticks developed a strong inflammatory reaction to the components of tick saliva, and had purple papules with necrosis in the centre of the lesion. The tick bite areas exhibited scars and hyperpigmentation. Conclusions. Individuals attacked by A. reflexus several times are at risk of development of severe persistent local reactions to bites. Pigeon ticks, trophically associated with pigeons present abundantly in the Upper Silesian conurbation and other European urban habitats, pose a serious threat to public health.

Opis:
Dairy cows production plays a significant role in development of Podkarpackie Voivodeship. Progress in this production branch may depend on the dairy production support which is given after relevant types of actions are undertaken. The objective of the research was to determine changes in the level of welfare of production animals, evaluation of practice in dairy cows breeding in the province of Ropczyce and Sędziszów. Breeding documentation and control protocols of the Coordinated Veterinary Inspection Program were applied pursuant to the resolution (1) of the Minister of Agriculture and Rural Development of 28 June 2010 on minimal conditions of maintaining farm animal species. 10 production herds of dairy cows (n-240) and heifers (n=101) which produce ≥ 10200 kilo of milk per lactation were used to achieve this objective. Dairy production was observed during individual visits in farms. Surveys were carried out with farm employees with the use of properly prepared veterinary control protocols of the Coordinated Veterinary Inspection Program. Control results were obtained based on the respondents' opinion from controlling institutions, such as: The Agency for Restructuring and Modernization of Agriculture, Regional Veterinary Office and similar certified bodies.
Produkcja bydła mlecznego pełni istotną rolę w rozwoju województwa podkarpackiego. Postęp tej gałęzi produkcji, może zależeć od wsparcia produkcji mlecznej, które jest udzielane po podjęciu odpowiedniego rodzaju działań. Celem badania było określenie zmian w poziomie dobrostanu zwierząt produkcyjnych, ocena praktyk w hodowli bydła mlecznego w powiecie ropczycko-sędziszowskim. Wykorzystano dokumentację hodowlaną gospodarstw i protokoły kontroli SPIWet (Skoordynowany Program Inspekcji Weterynaryjnej), zgodnie z rozporządzeniem (1) Ministra Rolnictwa i Rozwoju Wsi, z dnia 28 czerwca 2010 r., w sprawie minimalnych warunków utrzymania gatunków zwierząt gospodarskich. Do osiągnięcia tego celu wykorzystano 10 stad produkcyjnych krów mlecznych (n = 240) i jałówek (n = 101), produkujących ≥10200 kg mleka za laktację. Obserwacja produkcji mlecznej odbywała się podczas indywidualnych wizyt w gospodarstwach. Wywiady przeprowadzono z pracownikami gospodarstw, przy wykorzystaniu odpowiednio przygotowanych protokołów kontroli weterynaryjnej - SPIWet. Wyniki kontroli uzyskano na podstawie opinii respondentów z instytucji kontrolujących, takich jak: Agencja Restrukturyzacji i Modernizacji Rolnictwa, Rejonowy Urząd Weterynarii oraz pokrewne organy certyfikowane.

Opis:
Spring-fed fens in Wardzyń represent the rare group of alkaline mires supplied by artesian groundwater. Using multidisciplinary methods (including sedimentological, hydrometric and hydrochemical, pollen, macrofossil, malacological, geochemical, radiocarbon dating, and stable oxygen and carbon isotope analyses) we have been able to (1) reconstruct the main phases of spring-fed fen development, and to (2) determine the cause of Neoholocene groundwater ascension responsible for the mire inception. These phases are characterized by cyclic organic (peat) and carbonate (tufa) sedimentation associated with the Holocene fluctuations in humidity and temperature. The beginning of the activation of hydrological systems (involving the flow of confined groundwater of the Cretaceous aquifer) at Wardzyń occurred in the Subboreal period of the Holocene, after a long episode of decreased humidity initiated ca. 4.2 ka cal BP.
