We investigated ladybirds overwintering in agricultural landscape near Brzozówka in Kampinos Forest (Central Poland). Altogether, 180 samples of litter were collected in six habitats: on psammophilous grassland, under Scots pines Pinus sylvestris on fallow, in patches of mixed pine and alder forests, and under freestanding oaks. In total, we recorded 141 ladybird individuals representing seven species: Anatis ocellata, Coccinella septempunctata, Coccinula quatuordecimpustulata, Exochomus quadripustulatus Hippodamia tredecimpunctata, Propylea quatuordecimpunctata, Psyllobora vigintiduopunctata, and Tytthaspis sedecimpunctata. The dominant species was C. septempunctata (111 individuals), followed by H. tredecimpunctata (15 ind.). The relatively high numbers of H. tredecimpunctata hibernating in the litter under pines is interesting. This species is associated with humid habitats in the growing season and was recorded in very low numbers in previous studies on the hibernation of ladybirds in Kampinoski National Park.
Celem przeprowadzonych badań było określenie wpływu wapna dolomitowego oraz popiołu fluidalnego, z węgla kamiennego, w połączeniu z preparatem mikrobiologicznym EM-1, na ogólną liczebność bakterii, grzybów, promieniowców oraz zawartość biomasy mikroorganizmów glebowych. Stwierdzono, że dodatek do gleby wapna dolomitowego, zwłaszcza w większej dawce, spowodował wzrost zawartości biomasy drobnoustrojów oraz liczebności bakterii i promieniowców glebowych. Wyraźniejszy wzrost ilości badanych drobnoustrojów zaobserwowano w glebie, do której wniesiono popiół fluidalny i preparat mikrobiologiczny EM-1.
The object of the research was to analyze the influence of coal ash from fluidized-bed combustion applied to light soil, and combined with the microbiological preparation Effective Microorganisms (EM-1), on changes of the iron and manganese content in cultivated plants of spring wheat and spring barley. Commissioned by the company Vattenfall, a field study on seven fertilizer variants was carried out in 2007-2009. The experiments were set up in Małyszyn near Gorzów Wielkopolski (Hodowla Roślin Strzelce sp. z o.o. Oddział Małyszyn) on light soil, soil valuation class IVb. Each plot covered 10 m2. The research was carried out in completely randomized blocks with four replications. Plant samples (grain and straw) were mineralized in a solution of nitric acid(V) and chloric acid(VII); afterwards the total content of iron and manganese was assessed. Application of coal ash to the soil resulted in a decrease of iron and manganese in spring wheat and spring barley grain and straw, especially in the second and third year of the experiment. Additionally, the enrichment of soil with the microbiological preparation EM-1 decreased the concentrations of iron and manganese in the plants. It was noted that the quantities of iron and manganese in the grain and straw of both wheat and barley were decreasing in the subsequent years of the experiment, as a result of which the plant content of these microelements in individual years was varied. To some extent, the above relationship can be explained by the fact that in the last growing season was characterized by the least rainfall. No influence of the applied coal ash on the Fe:Mn weight ratio was determined in grain from cv. Nawra wheat or cv. Lot barley.
The species richness and relative abundances of ladybird beetles (Coleoptera: Coccinellidae) were surveyed in 2014-2015 in Cedynia Landscape Park (NW Poland). In total, 50 species were found, of which the most common was the invasive Harmonia axyridis (PALLAS, 1773). Some of the species recorded in this study, such as Hyperaspis concolor (SUFFRIAN, 1843), Clitostethus arcuatus (ROSSI, 1794), Nephus bipunctatus (KUGELANN, 1794), N. quadrimaculatus (HERBST, 1783), Scymnus ater KUGELANN, 1794, S. limbatus STEPHENS, 1832, Novius cruentatus (MULSANT, 1846) and Cynegetis impunctata (LINNAEUS, 1767), have very rarely been reported in Poland.
Economic effects of racehorse stables management in Warsaw race track. Economic effects of racehorse stables management on the example of Warsaw race track in Służewiec in 2004-2006 were examined. The analysis of income as well as costs of keeping horses showed lack of profitability for this kind of activity. The profitability threshold would have been reached only if the sum of race prizes gained in races by the trained horses had been 6.43 times higher. The highest share in the structure of total costs in the subject stable were employees remuneration costs constituting over 50% of monthly costs connected with running the said stable.
Background. Superior mesenteric artery syndrome (SMAS) is a rare disease caused by the acute angle of branching of the superior mesenteric artery from the aorta. Material and methods. There were 63 patients (56 women and 7 men) with low body weight, who reported recurrent persistent abdominal pain, nausea, post-prandial vomiting, significant weight loss. All of them had abdominal ultrasonography performed with measurement of the angle of branching of SMA from the aorta. CBC, total bilirubin, AST, ALT, GT, ALP, amylase, lipase, albumins, iron, sodium, potassium, GFR, lipid profile, TSH, urinalysis were ordered. Additionally, esophagogastroduodenoscopy with Hp. test and esophageal impedance measurement in correlation with the reported ailments was performed. Results. Acid reflux impedance was diagnosed in 10 patients. There were >55 acid reflux episodes per day and a positive reflux sign (SI) for heartburn and nausea. Abnormal impedance recording of acid reflux was diagnosed in 17 patients. They had >21 episodes of non-acid reflux per day. Positive reflux sign (SI) was not confirmed for any non-acid reflux-related symptoms. Conclusions. It is justified to perform impedance pH monitoring in this group of patients as it allows to modify the therapy. The most important dietary recommendations are weight gain and understanding the cause of the disease.
The species richness and relative abundances of ladybird beetles (Coleoptera: Coccinellidae) were surveyed in 2016–2017 in the Warsaw Zoological Garden (Central Poland). In total, 29 species were found, of which the most common was the invasive Harmonia axyridis (PALLAS, 1773). Some of the species recorded in this study, such as Clitostethus arcuatus (ROSSI, 1794), Scymnus abietis (PAYKULL, 1798), Scymnus rubromaculatus (GOEZE, 1777), Platynaspis luteorubra (GOEZE, 1777), and Adalia conglomerata (LINNAEUS, 1758) have rarely been reported from Central Poland.
 Introduction: Ischaemia-reperfusion injury (IRI) is a factor leading to the damages of the transplanted kidney, what affects mainly the proximal tubules. Early monitoring of tubule damage can be an efficient tool to predict the allograft dysfunction. Present in proximal tubules, N-acetyl-beta-glucosaminidase (NAG) is a lysosomal enzyme whose excretion rises as a result of IRI or acute rejection. The aim of this study was to monitor the NAG urine activity to evaluate the early proximal tubule damage, and to try to predict the long-term function of the transplanted kidney. Material and methods: The study enrolled 87 Caucasian renal transplant recipients (61.7% males, 38.3% females, mean age 45.56±14.34 years). Urine samples were collected for NAG and creatinine analysis on the 1st day after transplantation, and then in the 3rd and 12th month. Protocol biopsies were performed in the 3rd and 12th month. Results: A significant positive correlation between NAG urine activity in the 3rd month after transplantation and creatinine concentration on the 14th (p=0.004) and 30th day (p=0.05), in the 3rd month (p=0.009) and after the 1st (p=0.005) and 2nd year (p=0.003) was observed. A statistically significantly higher urinary NAG activity in samples collected in the first 3 days and in the 3rd month after transplantation among patients with DGF (p=0.006 and p=0.03 respectively) was found. There was a significant positive correlation between NAG urine activity in the 3rd month and the grade of tubular atrophy in specimens collected in the 3rd (p=0.03) and 12th (p=0.04) month. Conclusions: Monitoring of NAG urine activity is useful in the evaluation of early proximal tubule damage and predicting the long-term function of the transplanted kidneys.
