Authors: Sayardoust Shariel , Gröndahl Kerstin , Johansson Eva , Thomsen Peter , Slotte Christer 
Published: February 2013

Background:Little is known about the long‐term outcome of oxidized surface oral implants, especially in periodontitis‐susceptible smokers. The aim of this study is to determine implant survival and marginal bone loss at turned and oxidized implants in smokers and never‐smokers with periodontitis.Methods:Forty smokers and 40 never‐smokers with experience of advanced periodontal disease, treated with implants 5 years previously, are included in this study. Groups were matched for sex, oral hygiene, and implant distribution, and patients were subgrouped by implant surface type (turned or oxidized).Results:The overall implant survival rate was 96.9% in never‐smokers and 89.6% in smokers. Compared with oxidized implants, turned implants failed more frequently in smokers. In smokers, mean (standard error of the mean) marginal bone loss at 5 years was 1.54 (0.21) mm at turned and 1.16 (0.24) mm at oxidized implants. In never‐smokers, significantly greater bone loss was found at oxidized implants, 1.26 (0.15) mm, than at turned implants, 0.84 (0.14) mm. Oxidized implants demonstrated similar bone loss for both groups. Turned implants lost significantly more bone in smokers. Compared with never‐smokers, the smokers’ likelihood ratio for implant failure was 4.68, 6.40 for turned and 0.00 for oxidized implants.Conclusions:The results of the study underscore the need for prevention and cessation of smoking. Turned implants failed more frequently and lost more marginal bone in smokers. In contrast, oxidized implants showed similar failure rates and bone loss in smokers and never‐smokers. Turned implants displayed less bone loss than oxidized implants in never‐smokers. Oxidized surface implants are more suitable for patients susceptible to periodontitis who smoke.

Abstract
Inconsistent roller cone/PDC bit performance drilling horizontally through the hard/abrasive Granite Wash reservoir in western Oklahoma has resulted in low ROP, increased operating days, and escalating drilling costs. The difficult Marmaton age wash formation is encountered at 11,000-13,000ft TVD and has unconfined compressive strength (UCS) in excess of 30,000 psi. The typical well requires drilling a curve to horizontal, then 4,000 ft of 6-1/8-in lateral borehole. Offsets analysis revealed that 1-4 RC/PDC bits are required to drill the curve in addition to 1-13 bits to finish the lateral. The operator required a technological solution to minimize bit consumption/trips to lower well construction costs while achieving directional requirements.
An analysis of the most troublesome wells was conducted and a mathematical-based predictive analysis software identified the changes required to efficiently deliver the directional objectives. The study indicated that using a 4¾-in high-power steerable turbodrill, with two bends and a specific stabilization setup coupled with an application-specific 6 1/8-in diamond impregnated bit would significantly increase BHA performance and enhance section economics. The operator's drilling team studied the recommendation and concluded the BHA had the potential to increase reliability and reduce operating costs drilling the difficult Marmaton Wash.
This new turbodrill/impregnated bit BHA was run in several Washita and Beckham County wells with outstanding results. In one well the BHA drilled 4,040ft of 6 1/8-in lateral hole section in a single-run saving the operator eight drilling days and $348,000USD vs plan. The assembly required steering only 17% of the time. The borehole was completed in 589hrs at an average ROP of 6.9ft/hr. This performance set several new world drilling records. The authors will present case histories that illustrate performance achievements in the horizontal section and provide details that contributed to the success of the unique BHA.

Abstract
In the vegetation season April-October 2010, the value of and the changes in Zntot., Cutot., Cdtot. and Pbtot. concentrations in the water of the Rusalka flow-through lake (with average water retention of ca 30 days) situated in the city centre of Szczecin were determined. Water temperature, pH, concentration of dissolved oxygen (with calculation of water saturation with O2), COD-Cr and BOD5, total hardness, - 3 HCO concentration (as total alkalinity), Cl-, - 24 SO , Mntot and Fetot were also determined. The data collected may be used to evaluate the ecological and chemical status of the surface waters under investigation. As far as the ecological status of the Rusalka Lake is concerned, the investigated waters were found, based on the official criteria being in force in Poland in evaluation of the ecological and chemical status of surface waters, to conform to water quality classes I and II considering total zinc and copper concentrations, temperature and dissolved oxygen concentration (except water inflow to the lake in August) as well as BOD5, - 24 SO and Cl- concentrations and pH value; however, they were always worse than water quality class II while taking the COD-Cr values into account. Regarding the chemical status of the investigated waters, total cadmium and lead concentrations were the levels exceeding the admissible values according to the official criteria in Poland. Changes in the values of indices being investigated along water flow path allowed stating that the equilibriums between the sedimentation and the resuspension and the dissolution processes during the research period were shifted towards sedimentation in case of Zn and Cd only, as well as of the organic matter sedimenting in the form of divalent cation- and divalent anion-sorbing gels. Although three phytoplankton blooms occurred in the body of water, unfortunately weak ones, the dissimilation processes prevailed over assimilation.
Strategies for Expressing Power Relationships in the Slovenian Translation of Amitav Ghosh's Novel the Hungry Tide
Authors: Karče Tina 
Published: February 2013

Abstract
The paper explores various narrative and rhetorical strategies for expressing power relationships in the Slovenian translation of Amitav Ghosh’s novel “The Hungry Tide”. Based on critical discourse analysis and the model of micro- and macrostructural shifts developed by van Leuven-Zwart, the paper provides a classification of the aforementioned strategies based on a pilot study of the source text and its translation into Slovenian. Illustrating the strategies with chosen examples, the paper then discusses the solutions adopted by the translator, focusing on general issues concerning the cultural transfer of relationships characterized by inequality in terms of social power.
Application of newtonian nudging data assimilation method in hydrodynamic model of flood flow in the lower Biebrza basin
Authors: Mirosław-Świątek Dorota 
Published: February 2013

Abstract
The paper presents a 1D hydrodynamic flood flow model employing a data assimilation procedure based on Newtonian nudging. Data assimilation was used to determine correctly the upstream boundary condition defined as a discharge hydrograph. In the model developed, “nudging to individual observations” method was used. The data chosen for assimilation were water table levels recorded by a D-Diver automatic sensor installed in the river channel c. 1.5 km below a computational cross-section opening the analysed stretch of the river and the adjacent valley. This hydrological model of flood flow containing the data assimilation procedure is based on a one-dimensional Saint-Venant system of equations (dynamic wave model). The calculations were performed for the 2010 spring flood event at a 20-km stretch of the river and the floodplain in the upper part of the Lower Biebrza Basin. Modifying the boundary condition by using data assimilation has dramatically improved the accuracy of water table predictions during floods in the area of the Lower Biebrza Basin.
Trichinosis in Lublin Province in 2003-2010 on a Background of Wild Boar`S Population Dynamics
Authors: Flis Marian 
Published: February 2013

Abstract
The research aimed at evaluating the epizootic and epidemiological situation of trichinosis during the last 8 years in Lublin province on a background of progressing increase in wild boar population within the region and in the whole country. Data for the study were taken from the report on the results of the official examination of slaughter animals and meat, poultry, game, lagomorphs and aquaculture animals and six reports on the number of trichinosis cases found at wild boars and domestic swine. In order to evaluate the trichinosis epidemiological situation within the region, reports of the National Institute of Public Health-National Institute of Hygiene on the number of identified trichinosis cases in people, as well as the number of hospitalised patients were presented. In addition, information on the population and hunting achievement of wild boars in hunting circuits of Lublin province during the last 8 years was enclosed. The number of identified trichinosis cases in meat of wild boars from Lublin region increased 9 times, while the percentage of trichinosis occurrence in reference to the number of examined carcasses almost 3-fold. At the same period, the number of porcine carcasses, in which trichinosis was found, decreased by over 4 times. Over double increase in wild boar population on the studied area was observed during the evaluation. Dynamic increase in the population size - in an aspect of the species population interaction with the living habitat, and in the form of the increase in the number of damages of crops and cultivation fields - contributed to intensified hunting pressure towards the species expressed as almost 3-fold increase of wild boar hunting. Analysis of epizootic and epidemiological situation of Poland indicates that wild boar meat was the principal source of trichinosis during the studied period. Considering Lublin province, the number of identified trichinosis cases is still high as compared to eastern and central provinces. Meanwhile, when compared to western and northern Poland, the level of trichinosis invasion can be considered as low. Furthermore, the trichinosis morbidity among people, that does not exceed 0.18/100 thousand inhabitants, can be regarded as low. Nevertheless, the fact of underestimating the necessity of both wild boar’s and swine’s meat examination seems to be alarming

Published: February 2013

Abstract
Results of supravital and post-mortem observation of embolic-thrombotic complications in dogs, in the course of endotoxaemia induced by pyometra and phlegmonous pneumonia due to infection with Pseudomons aeruginosa, or endomyocarditis caused by Staphylococcus aureus infection were described. Multiorgan embolic-thrombotic complications were diagnosed in all presented cases. Most probably, the complications developed due to thrombocytopoenia secondary to platelet activation and exacerbation of endotoxin-induced DIC syndrome. In all the dogs, a disturbed cardiac rhythm was diagnosed supravitally. The rhythm disturbances might reflect myocardial injury due to presence of bacterial endotoxins in blood. The myocardial injury was confirmed by histopathological examination.

Abstract
The objective of this study was to evaluate the effect of dietary conjugated linoleic acid (CLA) and false flax (Camelina
sativa) seed oil (CS) on bone quality in broiler chickens. Experiment was carried out on 96 chickens randomly divided into four groups: control group fed diet with sunflower oil (SO) and three experimental groups fed diet with addition of CLA (2.86% starter, 4.32% grower) and diet with addition of CLA (1.43% starter, 2.16% grower) and SO or CS (1.43% starter, 2.16% grower). On the 35th d of life eight birds per treatment were slaughtered and the femur, humerus, and tibia were isolated for further analysis. Using DXA method, bone mineral content (BMC) and bone mineral density (BMD) were measured. Furthermore, weight and length of bones were assessed. The weight, BMD, and BMC in chickens from CS+CLA group were significantly higher when compared with CLA group. The significant differences were noted for BMC between control and CS+CLA birds. No marked differences of bone parameters were observed between control group and CLA, and SO+CLA groups. In conclusion, the results indicate that false flax oil and CLA can replace sunflower oil in chickens feeding, and demonstrate the effectiveness of false flax oil on the enhancement of bone properties in broiler chickens.

Published: February 2013

Abstract
This paper describes the quantitative method of determination of chosen substances from resorcylic acid lactones group: zeranol, taleranol, α-zearalenol, β-zearalenol, and zearalanone in bovine muscle tissue. The presented method is based on double diethyl ether liquid-liquid extraction (LLE), solid phase extraction (SPE) clean up, and gas chromatography mass spectrometry (GC-MS) analysis. The residues were derivatised with a mixture of N-methyl-N-trimethylsilyltrifluoroacetamide, ammonium iodide, and DL-dithiothreitol (1,000:2:5, v/w/w). The GC-MS apparatus was operated in positive electron ionisation mode. The method was validated according to the European Union performance criteria pointed in Decision Commission 2002/657/EC. The average recoveries of all analytes at 1 μg kg-1 level were located between 83.7% and 94.5% values with the coefficients of variation values <25%. The decision limits (CCα) and detection capabilities (CCβ) for all analytes ranged from 0.58 to 0.82 μg kg-1 and from 0.64 to 0.94 μg kg-1, respectively. The procedure has been accredited and is used as a screening and confirmatory method in control of hormone residues in animal tissues.

Published: February 2013

Abstract
The objective of the presented study was to compare rubidium concentration in different organs of bitches, depending on their health state. Samples of muscles, liver, and kidneys collected post mortem from 45 animals, at the age of 1-8 years, were examined. Chemical analysis was conducted using the inductively coupled plasma atomic emission spectroscopy method. The contents of rubidium in particular organs varied from 2.07 to 4.52, from 1.25 to 3.81, and from 1.32 to 3.78 mg·kg-1 of wet weight for muscle, kidney, and liver samples, respectively. The highest values were observed in animals with neoplastic disease and the lowest in healthy animals. These differences were highly statistically significant.

Authors: Kowalczyk Andrzej , Urbaniak Kinga , Markowska-Daniel Iwona 
Published: February 2013

Abstract
Phylogenetic analysis of the genes determining influenza virus subtype - haemagglutinin (HA) and neuraminidase (NA), was performed. The results showed that the Polish H1N2 isolate (A/Swine/Poland15817/2011) was reassortant of human-like swine H1N1 and human-like swine H3N2 origin. The novel isolate was presented to have a close phylogenic relationship with one of the latest European isolates of H1N2 (A/SW/Gent/102/2007 and A/SW/Hungary/13509/2007). Our evolutionary analyses also suggested that the HA and NA genes evolved in a significantly higher rate of synonymous substitutions after they were introduced from human to swine and established the European H1N2 swine lineage.
Influence of Magnesium on the Deposition of Cadmium in Rats
Authors: Grosicki Andrzej 
Published: February 2013

Abstract
Magnesium chloride was given via drinking water (500 mg Mg/L) to rats exposed intragastrically to cadmium (cadmium 109) at a dose corresponding to 10 mg/kg diet for 7, 14, 21, and 28 d. The results provided the evidence that magnesium decreased cadmium retention in the duodenum, kidneys, and liver after 7 d. Significant reduction in cadmium retention was also found on days 14 d and 21 in kidneys. No significant decreases in cadmium retention in the organs examined were noted after 28 d. The results suggest that beneficial action of magnesium on body cadmium accumulation ceased with time after the two metal administration.

Published: February 2013

Abstract
The study aimed at the determination of dynamic relationship between mineralisation processes and antioxidative/oxidative status during the development of osteopenia. One hundred and two healthy female Wistar rats at the age of 2 months and initial body weight of 200 g were used in the experiment. The rats were divided into control (CON, n=6), sham operated (SHO, n=48), and ovariectomised (OVX, n=48) groups. Animals from SHO (n=6) and OVX (n=6) groups were sacrificed every week during 8 weeks of the experiment in order to detect dynamic changes in examined parameters. The samples were collected weekly from day 7 to day 56. The femora were examined with the use of DXA (bone mineral density) and pQCT (area, mineral content, volumetric density of trabecular and cortical part of distal femora). The pQCT scans were performed 5 mm from distal end of the tibia. The determination of activity of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in haemolysates of erythrocytes were performed spectrophotometrically. Obtained data showed wave like changes in both enzyme activities and bone parameters and indicated the importance of the 2nd-3rd and 5th-6th week after surgery as a key moment for bone metabolism and activity of enzymatic antioxidative defence during the development of osteopenia induced by bilateral ovariectomy. The obtained results proved that alterations in activity of GSH-Px and SOD, and pQCT ahead the changes registered by DXA by 7 d.
Prepubic Minilaparotomy as the Surgical Approach in Treatment of Prostate Disorders in Dogs. A Cadaver Study
Authors: Trębacz Piotr , Galanty Marek 
Published: February 2013

Abstract
The aim of the study was to assess the prepubic minilaparotomy approach in the surgical treatment of prostatic disorders in dogs. The technique of a limited approach to the prostate was developed on the fresh cadavers of 14 intact adult male dogs, diversified in regard to size and body weight. The abdominal cavity was opened in midline, from the right-sided prepubic parapenile incision. The cut was limited to 7 cm. Afterwards, it was expanded by self-retaining retractors: Gelpi, Weislander, Finnochetto Baby, and Adson. Finnochetto Baby and Gelpi retractors used in pairs enabled an adequate exposition of the prostate in small dogs. The Finnochetto Baby retractor enabled an adequate exposition of the prostate in medium dogs and the Adson retractor - in large and giant dogs. The Weislander and Gelpi retractors used individually did not allow for sufficient access to the prostate in any group of the cadavers. Prepubic minilaparotomy can be a useful surgical approach in the treatment of prostate disorders in dogs. It can be used especially for minor surgical procedures, e.g. sampling of large tissue specimens for histopathological examination, partial prostatectomy, or treatment of intraparenchymal cavitary lesions.
The role of histopathology in the diagnosis of dermatophytoses / Značaj patohistološkog nalaza u dijagnostici dermatofitoza
Authors: Gocev Đorđi , Damevska Katerina 
Published: February 2013

Abstract
Histopathological analysis is not a routine procedure for diagnosing fungal skin infections. In the histopathological specimens, fungi are visible only when using special stain such as periodic acid-Schiff (PAS). However, histopathological analysis may not be performed in small laboratories. Histopathological characteristics of fungal skin infections are not specific. In all skin biopsy cases, obtained without clinical suspicion of fungal infection, the knowledge of certain, most frequent histopathological reaction patterns, as well as specific histopathological indicators (a diagnostic histopathological “clue”), of certain superficial mycoses e.g., dermatophytoses, may raise a suspicion of fungal infection and warrant a fungal-specific staining. A retrospective analysis of all PAS-stained sections was carried out. All PAS-positive biopsy specimens were assessed for clinical features, histopathological patterns of skin reactions, and presence of histopathological indicators. Our results have shown that out of the total of 361 PAS-stained sections, fungal hyphae were identified in 12 (3.3%) specimens. In 5 (1.4%) cases, the diagnosis of fungal infection was suspected on clinical grounds, while in 7 (1.9%) cases detection of fungi was an unexpected finding. The most frequent type of histopathological pattern was spongiotic, and the most frequent histopathological indicator was the presence of neutrophils within the epidermis. Our results confirm that dermatophytoses may present with clinical and histological non-specific findings. PAS staining represents a relatively cheap and simple fungal-specific staining. It has been suggested that it not only confirms that the selected material is actually invaded, but also reduces the number of false-negative direct reports, where fungi are cultured from a microscopically negative specimen. Apart from a small percentage of positive findings, our results justify the need for routine PAS staining of all clinically and histologically non-specific inflammatory skin conditions.

Published: February 2013

Abstract
Hydroa vacciniforme is a rare, idiopathic, chronic photodermatosis that usually begins in childhood and resolves spontaneously in early adulthood. It is characterized by appearance of vesicles on sun-exposed areas. The vesicles crust and heal within one to six weeks, leaving vacciniform/varioliform scars. We report an 11-year-old boy with a 5-year history of recurrent blisters on sun-exposed areas that deteriorated each summer. He was treated with antimalarials, topical photoprotective agents, sun avoidance, dietary fish oil and supplementary doses of vitamin D3. Strict adherence to the regimen resulted in remission.
