Opis:
Bacterial production, primary production and a number of other environmental factors were measured during six cruises in the Gulf of Gdańsk conducted in various seasons from 1995 to 2001. Bacterial production (BP) in the epipelagic layer ranged from 1.5% (April) to 80% (July) of the gross primary production (PP). Significant differences were observed between the BP/PP ratios in estuarine and open-water areas. The highest values were recorded in the coastal area and near the mouth of the river Vistula. It suggests that allochthonous organic matter has a great influence on BP. The correlations between particular parameters and regression analyses indicated that BP in the Gulf of Gdańsk depended on temperature, organic nitrogen concentration, PP, chlorophyll a concentration, organic phosphorus concentration, salinity and biochemical oxygen demand. Of all the independent variables, the temperature had the greatest impact on BP (R2 = 0.62). There was an inverse parabolic relationship between bacterial production and temperature. It appears that above a temperature of 12◦C bacterial production depended on substrates to a higher degree than on temperature. The negative correlation between BP and concentrations of mineral nitrogen and phosphorus in the annual cycle were probably due to an indirect dependence. A multiple regression equation, which included temperature and organic phosphorus concentrations, explained 78% of the variation in BP. Increasing BP resulted in an increasing biomass of bacterivorous nanoflagellates and of bacterivorous ciliates, which is indicative of bottom-up control in this segment of the trophic chain.

Introduction. COVID-19 is a disease caused by SARS-Cov-2 that has reached the pandemic status and has infected in one year more than 62 million people. Clinical symptoms range from barely noticeable to very severe. It is crucial to recognize imaging patterns of COVID-19, allowing for better diagnosis and treatment. Diagnostic imaging is also essential in monitoring patients in the course of the disease. Objective. In our pictorial review we describe the most common pulmonary manifestations of COVID-19, and show the typical and non-typical features of COVID-19 encountered in our hospital in Lublin, Poland. Imaging the disease progression is also visualized to help realize how pulmonary changes occur over the time. State of knowledge and Conclusions. COVID-19 involves both lung parenchyma and interstitium and has multiple imaging features, varying form ground glass opacities (GGO), consolidations, reticular interstitial pattern, honeycombing or crazy- paving. Mediastinal and hilar lymph node enlargement or pleural effusion may appear, but are rare and atypical. GGO are located peripherally, bilaterally and predominantly in the lower lobes, and in the early stage are better seen on CT imaging. Progression of imaging findings take different times, with the peak of of imaging features appearing around 10–14 days after initial symptoms. While it is harder to discern subtle changes on CXR, progression can be very well monitored by his method. Final pulmonary consequences of the disease should be assessed with the use of CT.

Opis:
The aim of the study was to develop and validate real-time PCR method for the quantification of Lawsonia intracellularis and Brachyspira hyodysenteriae in porcine feces. Before the optimization process was performed two different extraction methods were compared to select the more efficient one. Based on the results achieved at this stage the boiling procedure was rejected and a commercially available silica-membrane based method was chosen for further analysis. The primers and the Taqman probe for B. hyodysenteriae and L. intracellularis were based on the sequence of NADH oxidase gene and 16S rDNA gene, respectively. The detection limit of the real-time PCR for suspension of feces inoculated with B. hyodysenteriae and L. intracellularis was determined to be 1.5x103 CFU/ml and 6.5x101 CFU/ml, respectively. The results of this study demonstrate that our real-time PCR is able to detect low number of B. hyodysenteriae and L. intracellularis cells which is satisfying in routine diagnosis of swine dysentery and proliferative enteropathy. Therefore, it is possible to identify both subclinically infected pigs and those representing an acute form of mentioned diseases. In summary, the quantitative real-time PCR is useful for routine diagnosis of L. intracellularis and B. hyodysenteriae. Compared to conventional PCR, the new validated quantification method based on real-time PCR is fast and with reduced risk of laboratory contamination. The novel technique is specific and even more sensitive than the previously used one. Furthermore, the new real-time PCR enables quick detection and quantification of both pathogens in fecal samples, which helps to estimate the health status of a pig herd.

Opis:
The paper presents the results of investigations concerning the number, distribution and physiological activity of sulphate-reducing bacteria (SRB) inhabiting the bottom sediments of the Gulf of Gdańsk. The numbers of this group of bacteria range between 0.76 × 103 and 1.27 × 104 cells per g wet sediment. The bacterial sulphate reduction rate in bottom sediments of this area of the Baltic Sea varies from 1.89 to 31.6 nM SO2− 4 g−1 24 h−1. The numbers of SRB and their physiological activity were subject to considerable seasonal fluctuations, maximum values being noted in summer (June) and minima in spring (April). A direct relationship has been found between the number of SRB and hydrogen sulphide concentrations; there is, however, no such relationship with reference to sulphate concentrations. The numbers and distributions of SRB demonstrated considerable variation in a depth profile of bottom sediments. SRB inhabiting the bottom sediments of the Gulf of Gdańsk were able to use three different organic substrates (lactate, acetate, propionate) as electron donors and as carbon and energy sources.

Introduction and aim. Computer techniques are increasingly used in speech therapy. The aim of the work is to present the results of the preliminary evaluation of the new “Talk To Me” application and its functionality in the treatment of speech development delays. Material and methods. The study was conducted in 3 groups of children: the study group with the use of the “Talk To Me” application, the conventional therapy group and the control group - in the case of both groups with the intervention, additional reinforcements were used. All children included in the project showed delays in speech development. The recorded age of children in all analyzed groups ranged from 2 to 6 years. In order to verify language progress, the Scale of Language Skills Acquisition in the Field of Communication Competence was used. Results. Acquisition of language skills varies depending on the group affiliation. The analysis of simple main effects for the time of measurement showed that in each group the differences between successive measurements turned out to be significant. In the study group, the increase in language skills differs from the other two groups (p< 0.001). However, there is no difference between the groups with conventional and control therapy (p=1.00). Conclusion. Analysis of the research results allows us to conclude that the “Talk To Me” application is a tool that significantly affects the speed of therapy progress in the case of speech development delays concerning communicative competence.

Opis:
The paper reports on the growth conditions of Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ single crystals in both pure and Yb, Co, Mn doped systems. The crystals were grown by the Czochralski method using an intentional concentration of the above-mentioned ions at a level of 0.5 mol.%. The pure and Mn-doped crystals were found to be highly transparent and clear. The crystals doped with Yb$\text{}_{2}$O$\text{}_{3}$ had a lot of precipitations making them opaque. The Co-doped crystals were purple-blue in colour and highly transparent. The growth of Yb and Co doped Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ crystals was reported for the first time in this paper. Absorption was measured in the range of 200 to 3200 nm, moreover analysis of changes in the absorption spectrum ofγ-irradiated pure and doped Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ crystals was performed. Some thermoluminescence properties were measured, e.g. energies and lifetimes of the traps of different charge carriers occurring in the crystals at low temperatures.

Opis:
Purpose: Correct foot structure is important due to locomotion and postural stability. The aim of this study was to determine the relationships between morphological foot structure and balance indices in a quiet standing position in women over 65 years of age. Methods: The study included 116 women aged 65-90 years. The mean age was 70.6±8.4 years and BMI 29.1±3.4 m/kg2. The measured indices included postural control while standing on both feet and photogrammetric foot evaluation. An analysis was performed of the selected foot and balance indices. Results: There were no significant differences observed in the feet structure. Certain correlations between some foot indices and the indices of postural control were noted. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis. Conclusions: The differences between the indices and morphological indices for the right and the left foot are not significant, which indicates the proportionate formation of feet in the individual life. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis.

Opis:
The article describes three interlaboratory experiments concerning 222Rn determination in water samples. The first two experiments were carried out with the use of artificial radon waters prepared by the Laboratory of Radiometric Expertise (LER), Institute of Nuclear Physics, Polish Academy of Sciences in Kraków in 2014 and 2018. The third experiment was performed using natural environment waters collected in the vicinity of the former uranium mine in Kowary in 2016. Most of the institutions performing radon in water measurements in Poland were gathered in the Polish Radon Centre Network, and they participated in the experiments. The goal of these exercises was to evaluate different measurement techniques used routinely in Polish laboratories and the laboratories’ proficiency of radon in water measurements. In the experiment performed in 2018, the reference values of 222Rn concentration in water were calculated based on the method developed at LER. The participants’ results appeared to be worse for low radon concentration than for high radon concentrations. The conclusions drawn on that base indicated the weaknesses of the used methods and probably the sampling. The interlaboratory experiments, in term, can help to improve the participants’ skills and reliability of their results.
