Abstract
AbstractIncorporating zinc oxide nanoparticles (ZnO NPs) into cement mortars may provide additional functions, e.g., self-cleaning and antibacterial or electroconductive ability. However, these NPs are also known for their potential toxicity. During the life cycle of a cement mortar, various abrasive forces cause the release of admixtures to the natural environment. The effect of the released NPs on model microorganisms has not been extensively studied. Previous studies have shown that nanomaterials may affect various microorganisms’ physiological responses, including changes in metabolic activity, biofilming, or growth rate. In this study, we have focused on evaluating the response of model microorganisms, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Candida albicans, towards ZnO nanoparticles released from cement mortars in different deterioration scenarios. The addition of ZnO nanoparticles to cement mortars had a noticeable effect on impeding the strength development. We have also detected that depending on the deterioration scenario, the release of ZnO nanoparticles was varied. Our studies have also shown that even though the release of nanoform ZnO could be limited by poor dispersion or the used filtration technique, the eluates have caused slight but statistically significant changes in the physiological features of studied microorganisms showing relatively low toxicity.

Early pre- and postsynaptic decrease in glutamatergic and cholinergic signaling after spinalization is not modified when stimulating proprioceptive input to the ankle extensor α-motoneurons: Anatomical and neurochemical study. PLoS One 2019; 14:e0222849. [PMID: 31557259 PMCID: PMC6763201 DOI: 10.1371/journal.pone.0222849] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2019] [Accepted: 09/08/2019] [Indexed: 12/23/2022] Open
Abstract
Alpha-motoneurons (MNs) innervating ankle extensor muscles show reduced peripheral inputs from Ia proprioceptive afferents and cholinergic afferents after chronic spinalization (SCT). That phenomenon is not observed on ankle flexor MNs, indicating a smaller vulnerability of the latter MNs circuit to SCT. Locomotor training of spinal rats which partially restored those inputs to extensor MNs tended to hyper innervate flexor MNs, disclosing a need for selective approaches. In rats with intact spinal cord 7-days of low-threshold proprioceptive stimulation of the tibial nerve enriched glutamatergic Ia and cholinergic innervation of lateral gastrocnemius (LG) MNs, suggesting usefulness of selective stimulation for restoration of inputs to extensor MNs after SCT. Accordingly, to examine its effectiveness after SCT, tibial nerves and soleus muscles were implanted bilaterally, and for MN identification fluorescence tracers to LG and tibialis anterior (TA) muscles were injected two weeks prior to spinalization. Stimulation of tibial nerve, controlled by H-reflex recorded in the soleus muscle, started on the third post-SCT day and continued for 7 days. Nine days post-SCT the number and volume of glutamatergic Ia and of cholinergic C-boutons on LG MNs was decreased, but stimulation affected neither of them. Postsynaptically, a threefold decrease of NMDAR NR1 subunit and thirtyfold decrease of M2 muscarinic receptor transcripts caused by SCT were not counteracted by stimulation, whereas a threefold decrease of AMPAR GluR2 subunit tended to deepen after stimulation. We conclude that LG MNs, supported with proprioceptive stimuli after SCT, do not transcribe the perceived cues into compensatory response at the transcriptional level in the early post-SCT period.

Abstract
The objective of our research work was to develop a model that could be used to determine resistance of air flow through a bed of organic material processed in composting operation. The raw material used for testing was organic fraction below 80mm separated from municipal waste. The range of process parameters values treated as independent variables was: for hydraulic load 8.49÷50.96m3·m-2·h-1, thickening coefficient 0.69÷0.94 and airflow direction from the bottom upwards and vice versa. The research work lasting 19÷25days was performed in three independent series varying in the bed height. Material humidity was maintained at a constant level of approx. 45%. Analysis of simulation results allowed for selection of MLP/5-9-1 neural network. High quality of such obtained neural network was confirmed by statistical evaluation indicators represented by a coefficient of correlation between the forecast and real values (0.906) and the range of standardized rests of the forecast results (4.082÷5.453).

Abstract
INTRODUCTION The aim of our study was to determine the antibacterial activity of cinnamon bark oil against Gram-positive and Gram-negative isolates belonging to Staphylococcus, Enterococcus, Enterobacter and Acinetobacter genera come from different clinical specimens. METHODS The microdilution method was used to determine the minimum inhibitory concentration--MIC for cinnamon bark oil. Susceptibility testing to antibiotics was carried out using disc-diffusion method. RESULTS Our investigations showed that the tested cinnamon bark oil was inhibiting activity against all isolates. The MIC for Gram-positive bacteria were between 01.25 and 1.5 μl/ml and for Gram-negative between 1.0 and 1.75 μl/ml. The tested bacteria come from Staphylococcus, Enterococcus, Enterobacter and Acinetobacter genera were susceptible to essential oil obtained from Cinnamomum zeylanicum Ness in low concentrations, despite the fact that the bacteria characterized the high resistance to recommended antibiotics. No correlation was found between the antibiotic resistance of the bacterial strains and their sensitivity to essential oil. CONCLUSIONS The cinnamon bark oil due to the strong activity can be used as alternative antibacterial agents in cosmetics, toiletries and disinfectants applied in hospital environment.

Abstract
The aim of the study was to assess the antifungal activity of preparation „fin Candimis” (oregano essential oil) against yeast-like strains belonging to the genus <em>Candida</em>. During the investigation, there were used up nine <em>Candida albicans</em> strains and ten C. glabrata strains isolated from different clinical material, along with one <em>C. albicans</em> demonstration strain ATCC 90028. The oregano essential oil, utilized in the study, was obtained from fresh leaves of <em>Origanum vulgare</em> L. and bore a trade name „fin Candimis”. According to data yielded by its manufacturer, concentration of pure oregano essential oil in preparation „fin Candimis” totals up to 210 mg/ml. The susceptibility of the <em>Candida</em> strains to preparation „fin Candimis” was assessed by means of the disc-diffusion method, upon the Sabouraud solid medium (after a 24-hour incubation of the cultures at temperature of 37 degrees centigrade); the oregano essential oil had been diluted in 1 ml of DMSO, according to the geometrical progression. A measure of the antifungal activity of preparation „fin Candimis” was the minimal inhibitory concentration (MIC), in terms of the fungus growth. Preparation „fin Candimis” is capable of being applied in the prevention and treatment of candidiasis – alone, or as a natural adjunctive agent. The <em>C. albicans</em> strains are more susceptible to preparation „fin Candimis” in comparison to the <em>C. glabrata</em> ones.

Abstract
The influence of hydrogen on the microstructure of two types of austeno-ferritic duplex stainless steel (Cr26-Ni6 model steel and Cr22-Ni5-Mo3 commercial steel), each of them after two thermo-mechanical treatments, was investigated. The aim of this study was to reveal microstructural changes appearing during the hydrogen charging and particularly to clarify the occurrence of phase transformations induced by hydrogen. The specific microstructural changes in the ferrite (alpha) and austenite (gamma) of both types of steel were observed. A strong increase of dislocation density was noticed in the alpha phase. In the case of model steel, longer hydrogen charging times led to significant ferrite grain refinement. In the commercial steel, the strips and twin plates appeared in the ferrite after hydrogenation. The appearance of stacking faults was revealed in the gamma phase. The martensite laths appeared in austenite after longer hydrogenation times. It seems that the microstructural changes gave rise to the formation of microcracks in the alpha and gamma phases as well as on the alpha/gamma interphase boundaries.

Abstract
UNLABELLED The purpose of the study was to evaluate the long-term results of uncemented total hip arthroplasty (THA) in young patients (below 50 years of age) with dysplastic coxarthrosis. In the last 20 years, 862 primary uncemented THA, were implanted in our Institution. This surgery was performed in 459 patients. From this group 220 hips in 177 patients (167 women and 10 men), who had dysplastic coxarthrosis, were included in our study. The left hip was operated in 66 and the right one in 68 patients. Bilateral surgery was performed in 43 cases. The means age at the time of hip surgery was 38.3 years (range from 18 to 49 years). The mean follow-up was 9.3 years (range from 2 years to 18.6 years). In 167 (75.8%) patients the operative treatment of DDH was performed during the early childhood (Colonna-Zahradnicek procedures, Dega, Pemberton and Salter pelvic osteotomies). Only 39 (17.7%) patients were treated in the childhood conservatively by means of overhead extension, Frejka pillow or Pavlik harness. All patients were evaluated clinically and radiological. For clinical evaluation the classification system proposed by Merle d'Aubigne and Postel with Chamley modification was used. For radiological evaluation of the steam implantation the classification system proposed by De Lee and Chamley was used and for the cup implantation the system by Gruen and Moreland. The femoral head displacement prior to THA surgery was classified according to Crowe at all. classification. Based on above mentioned criteria in 26 hips (11.8%) the final result was graded as very good, in 61 cases (27.7%) as good, in 94 hips (42.7%) as satisfactory and in the remaining 39 cases (17.8%) the final result was poor. We observed a very strong correlation between clinical and radiological results. According to Crowe and all. classification, in class I we noted 19 (61.3%) very good, 11 (35.5%) good, 1 (3.2%) satisfactory results. In class II in 5 cases (6.6%) the results was very good, 25 (32.9%) good and in 39 (51.3%) satisfactory results. In class III only in 2 cases the final result was graded as very good, and good in 23 hips (25.8%). In class IV there was no very good result, and we observed 19 (21.4%) poor results. In analyzed group in 37 (16.8%) patients the revision hip surgery was necessary because of aseptic prosthesis loosening. CONCLUSIONS The treatment of dysplastic coxarthrosis by means of THA is difficult. The high level of experience is necessary to perform this type of surgery. This type of THA should be performed only in selected orthopaedic centers. Starting the surgery one has to think about complications.

Abstract
Background. Total knee alloplasty (TKA) is standard treatment for advanced gonarthrosis. Proper rehabilitation of the operated joint and the patient is essential in order to achieve a satisfactory functional outcome. The aim of our study was to compare rehabilitation methods used for patients recovering from TKA in the Orthopedic Clinic of the Medical University in Łódź, Poland. Material and methods. We studied 186 patients operated for advanced gonarthrosis, ranging in age from 29 to 80 (average 65.8), who had received 197 endoprotheses. From 1986 to 1989 the rehabilitation program included isometric exercises of the muscles in the operated joint, general fitness exercises in bed, and passive exercises of the knee conducted by a physiotherapist. The average stay during this period was 19.7 +/- 2.5 days. In 1989, continuous passive motion (CPM) using an electric rail was introduced to the rehabilitation program. Results. Thanks to the earlier additional flexibility of the operated joint, active exercises and weight bearing on the operated limb could be accelerated. The patients left the Clinic 2 weeks after surgery (13.6 +/- 2.5 days). The change in the rehabilitation program produced a statistically significant increase in the average range of flexion in the operated joint (p = 0.000001) in a significantly shorter time (p = 0.0000). Conclusion. Introducing CPM to the rehabilitation of TKA patients accelerates their progress and reduces hospitalization time, which improves the patients' emotional comfort and enables a faster return to an active life in society.

Abstract
Leukemia inhibitory factor (LIF) is a pleiotropic glycoprotein belonging to the IL-6 family of cytokines. It shows a wide range of biologic activities that include the growth promotion and cell differentiation of different types of target cells, influence on bone metabolism, cachexia, neural development, embryogenesis and inflammation. LIF has potent proinflammatory property, being the inducer of the acute phase protein synthesis and affecting the cell recruitment into the area of damage or inflammation. LIF is also one of the cytokines that are capable to regulate the differentiation of embryonic stem cells, hematopoietic and neuronal cells. Due to its polyfunctional activities, LIF is involved in the pathogenic events and development of many diseases of various origin.

Abstract
Increasing use of elctromagnetic fields (EF) in the treatment of various diseases may have potential impacts on fungi--possible aetiological factors of concomitant mycoses. The aim of this study was to investigate the effects of EF on miconazole susceptibility among fungi of the genus Candida showing confirmed pathogenicity in humans. Fifteen Candida strains obtained from patients were used and their susceptibility to miconazole was determined by diffusion in agar gel. Antifungal activity of miconazole was assessed as minimal inhibitory concentration (MIC) which was calculated for Candida strains not exposed to EF (control) and EF-exposed (3 experiments). In the majority of cases the susceptibility of Candida species to miconazole decreased (higher MICs) after the first week of EF exposure, regardless of the EF's parameters. This was followed by an increase in susceptibility (lower MICs) after the second week of exposure to EF of 2 mT intensity and frequency 3 Hz (experiment I) and an EF of 9 mT intensity and 12.5 Hz frequency (experiment II) relative to control. An increase in susceptibility (lower MICs) was observed in the second week of exposure, whatever the parameters of the EF. The application of low intensity, low frequency EF for a period of at least two weeks may be beneficial in the treatment of mycoses caused by pathogenic fungi of Candida genus.

Abstract
This work presents the epidemiology of dermatomycoses and their etiological agents of people living in the Lódź region, Central Poland, over the years 1987-1996. The analysis involved subjects referred by physicians to three major mycological laboratories in Lódź (covering the entire mycological diagnostics of the Lódź region). The study comprised a total of 25,737 persons aged 1-82. Positive results of mycological examinations were obtained for 14,084 (54.7%) patients. The total number of 14,295 positive mycological results included 6902 (48.3%) isolations of non-dermatophyte fungi. The non-dermatophytes included: Candida-like (69.8%), moulds (26.9%) and lipophilic yeasts (3.3%). The distribution of non-dermatophytes was characterized by dependence on sociodemographic features such as subjects' age, place of residence, education and occupation. Candida-like fungi are etiological factors of superficial infections of all clinical types whereas moulds were found to cause infections of finger and toe nails and periungual walls.

The study comprised a total of 25,737 patients. Positive mycological results were obtained for 14,084 patients (54.7%). The total number of 14,295 of positive mycological results included 6902 (48.3%) isolations of non-dermatophyte fungi. Among these positive results, isolations from subjects with infections of nails and periungual walls amounted to 2034 (29.5%). Candida albicans (59.9%) and Aspergillus sp. (17.3%) were major etiological factors of those infections. The decade in question was marked by a steady growth in incidence of the infections studied, especially over the years 1994-1996.

The vasopressin and oxytocin neurohypophysial content as influenced by bleeding or dehydration: effect of cholecystokinin octapeptide.

Abstract
The effect of CCK-8 (50 ng, i.c.v.) on the neurohypophysial vasopressin and oxytocin storage was estimated in haemorrhaged (1 ml per 100 g b.w.) male Wistar rats. In another experimental series rats dehydrated for three days were given CCK-8 in a daily i.c.v. dose of 50 ng. The neurohypophysial vasopressin and oxytocin content was bioassayed by pressor effect following Dekański or milk-ejection activity in vitro following van Dongen and Hays, respectively. The decrease of neurohypophysial vasopressin and oxytocin content, brought about by dehydration, was significantly less marked in animals treated with CCK-8. The depletion of neurohypophysial vasopressin and oxytocin content in haemorrhaged animals could be completely inhibited by earlier i.c.v. administration of CCK-8. It is suggested that hypothalamic cholecystokinin may serve as a modulator of neurohypophysial function.
