The aim of this research was to provide a detailed description of the morphology, topography, and histometry of rabbit accessory genital glands.
Seven male New Zealand White rabbits, 3-4 months of ...age and weighing 2.1-3 kg were used for the study. The whole urethra from the urinary bladder to the external urethral orifice accompanied by accessory genital glands was sliced at intervals of 1 mm. The serial sections were prepared with haematoxylin-eosin (H&E) and Movat-Russell modified pentachrome stain.
A detailed description of the morphology and morphometry was provided. The topography of the organs was explained on the basis of characteristic cross-sections on histological slides. The inconsistent nomenclature and descriptions of these glands by different authors were also discussed.
The morphometric analysis indicated that some of the glands described have similar dimensions in different individuals, while others like paraprostates revealed high diversity in the number of lobes, their size, and their structure. The accessory glands are also good topographic markers which precisely define the segment of the urethra. The terms "proprostate", "prostate", and "paraprostates" as the nomenclature of the prostate complex reflect the location of these glands well and indicate their common origin and function.
The aim of our study was to optimise an existing staining procedure: haematoxylin-eosin saffron (HES). The method follows the classical haematoxylin and eosin protocol with the addition of a staining ...step using natural saffron to better identify the collagen fibres.
The saffron solution was obtained by dissolving ground saffron stigmas in absolute alcohol. In order to test the HES method for its staining ability on four main types of collagen (I, II, III, and IV), specific tissues (skin, tooth, cartilage, aorta, spleen, and penis) were chosen.
The procedure showed a sharp differentiation between muscle, stained red or pink, and connective tissue, stained bright yellow or orange.
HES allows the diagnosis of reticulin fibrosis undetected in HE and in previous saffron staining procedures. HES represents an advantageous alternative to HE staining giving highly reproducible results with high diagnostic value.
The paper contains the results of the analysis of sodium alginate use as a material for making urethral stents, necessary for the treatment of urinary disorders. Strength tests of the material were ...carried out, analyzing the characteristics of the material in terms of its interaction with the urethra. The characteristics of the urethra, which is characterized by large deformations, were investigated experimentally. Based on the results of the experiments, geometric dimensions of the stent were developed. According to the results obtained, stent structure was developed, which was implanted into the rabbit urethra. The in vivo study confirmed the assumptions. The implanted stent was effectively and without damage expanded inside the urethra within the assumed diameter variation limits, free flow of urine during the urination was obtained after the implantation, and the proposed design fulfilled the strength assumptions resulting from the pressure of the urethra walls on the stent surface.
The aim of this paper is to analyze the changes in accident rates resulting from the privatization of forest operations. Data from the years 1990-2017 were obtained from the Statistical Forestry ...Yearbooks issued by Statistics Poland, and were analyzed for two periods: the time of intensive privatization (1991-2002) and the post-privatization period (2003-2017). The data from 1990 were treated as a benchmark. There were 14,626 accidents in total, of which 236 (1.61%) were fatal. The non-fatal accident rate in the whole forestry industry showed a decreasing trend in the study period (t = 2.27,
< 0.05). In the case of the fatal accident rate we can observe an upward trend; in the period of intensive privatization the average annual fatality rate was 0.11, and after privatization it was 0.18 (t = -2.68,
< 0.05). In both periods the fatality rate was twice as high in the private forestry sector as in the public sector. The number of working days lost declined in the public sector and increased in the private sector. An accident in the private sector resulted in 20 days' longer absence than one in the public sector. The study confirms that despite economic transition, accident rates in Polish forestry remain a serious issue. The main problem to be addressed is the increase in the fatal accident rate, especially in the private sector.
We deal with a viscoelastic fluid model in a rectangle domain with nontrivial velocity at the inflow and outflow area and slip boundary condition at the rest of the boundary. For this model we ...investigate the existence of local in time solutions. Then we present 2D simulations and we discuss the possibility of the derivation of 1D model by limit passage with the height of the rectangle to zero. Moreover, we present few 1D models that we support by simulations.

Orthorexia nervosa is a relatively new health problem, which explains limited knowledge about the phenomenon in society. Only a few empirical studies on the course of this disorder, its ...characteristics and prevalence have been conducted. Therefore, it is not possible to precisely estimate the scale of the phenomenon. Nevertheless, there are tools available to assess the risk of orthorexia, and methods for its treatment. It is necessary to do further research in this disorder and to educate society about its risk factors. This can translate into an improved diagnosis (and thus help to determine the scale of the phenomenon), and support the development of uniform diagnostic criteria.
