Estimating repeat sales residential price indices for Krakow
Authors: Głuszak Michał , Czerski Jarosław , Zygmunt Robert 
Published: April 2018

Research background: There are several methods to construct a price index for infrequently traded real estate assets (mainly residential, but also office and land). The main concern to construct a valid and unbiased price index is to address the problem of heterogeneity of real estate or put differently to control for both observable and unobservable quality attributes. The one most frequently used is probably the hedonic regression methodology (classic, but recently also spatial and quantile regression). An alternative approach to control for unobservable differences in assets? quality is provided by repeat sales methodology, where price changes are tracked based on differences in prices of given asset sold twice (or multiple times) within the study period. The latter approach is applied in renown S&P CoreLogic Case-Shiller house price indices.
Purpose of the article: The goal of the paper is to assess the applicability of repeat sales methodology for a major housing market in Poland. Previous studies used the hedonic methodology or mix adjustment techniques, and applied for major metropolitan areas. The most widely known example is the set of quarterly house price indices constructed by NBP ? especially for the primary and secondary market. The repeat sales methodology has not been adopted with significant success to date ? mainly because of concern regarding relative infrequency of transactions on the housing market in most metropolitan areas (thus a potentially small sample of repeated sales).
Methods: The study uses data on repeat sales of residential transactions in Krakow from 2003 to 2015. We apply different specifications of repeat sales index construction and compare respective values to the hedonic price index for Krakow estimated by NBP.
Findings & Value added: Findings suggest that repeat sales house sales indices can be used to track price dynamics for major metropolitan areas in Poland. The study suggests problems that need to be addressed in order to get unbiased results ? mainly data collection mechanism and estimation procedure.
Cluster analysis of effectiveness of labour market policy in the European Union
Authors: Rollnik-Sadowska Ewa , Dąbrowska Edyta 
Published: April 2018

Research background: In the era of demographic changes and the need for rationalization of public expenditure, the European Union social policy promotes the activation approach. In addition, a growing importance of increasing the effectiveness and efficiency of public entities can be noticed. These phenomena are visible in the implementation of the labour market policy. However, the EU countries represent a different approach to spending public funds on issues related to the implementation of labour market policy.
Purpose of the article: The authors are presenting the main theoretical assumptions concerning effectiveness and efficiency of labour market policy. Moreover, in the paper the EU countries are classified in clusters according to their level of expenditure on different categories of LMP. A comparison of the situation over ten years ? in 2004 and 2014 ? has also been conducted. In 2004, ten new members entered the EU, and the year 2014 presents the most current data in the analyzed area.
Methods: As a research method cluster analysis was applied. Cross-country labour market situation throughout the EU is presented by the analysis of the Eurostat data. The countries are grouped in clusters following Ward's and k-means methods.
Findings & Value added: There is a need to work out a complex evaluation of labour market policies in the EU to provide comparative analysis of the EU countries (or groups of countries). It would allow to determine the level of development of the country in terms of the efficiency of labour market policies. The EU countries with the best labour market indicators represent diverse levels of LMP expenditure.

Effective anti-adhesives of uropathogenic Escherichia coli
Authors: Ribić Rosana , Meštrović Tomislav , Neuberg Marijana , Kozina Goran 
Published: April 2018

Abstract
Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) are among the most common infectious diseases in humans. Due to their frequent occurrence in the community and nosocomial settings, as well as the development of resistance to the commonly prescribed antimicrobial agents, an enormous financial burden is placed on healthcare systems around the world. Therefore, novel approaches to the prevention and treatment of UTIs are needed. Although UPEC may harbour a plethora of virulence factors, type I fimbriae and P pili are two of the most studied adhesive organelles, since the attachment to host cells in the urinary tract is a crucial step towards infection. Design of receptor analogues that competitively bind to UPEC surface adhesins placed at the top of pili organelles led to the development of anti-adhesive drugs that are increasingly recognized as important and promising alternatives to antibiotic treatment of UTIs.

Abstract
To evaluate the efficiency of the probiotic strain Lactobacillus plantarum LS/07 in dextran sulphate sodium (DSS) induced acute colitis selected biochemical (activity of β-glucuronidase), microbiological (counts of lactobacilli and coliforms), and immunological (IL-6, IL-8, IL-13, NF-κB, MPO) parameters were assessed. Sprague-Dawley rats were divided into groups: Control, Acute colitis, and Probiotic. Acute colitis was induced using 5% DSS in drinking water for 7d. DSS induced an inflammatory process in the colonic tissue, increased the activity of β-glucuronidase (p<0.001), increased the counts of coliform bacteria and decreased lactobacilli counts (p<0.05), and activated the production of the measured parameters (NF-κB, MPO, IL-6, IL-8) except of IL-13. Lactobacillus plantarum LS/07 in the diet alleviated the DSS induced inflammatory process by inhibiting the production of IL-6, IL-8, the activities of NF-κB and MPO, and stimulated the production of IL-13. The probiotic reduced the activity of β-glucuronidase (p<0.05), increased lactobacilli counts and decreased coliform bacteria. These results indicate that dietary intake of Lactobacillus plantarum LS/07 suppressed the expression of markers playing an important role in the inflammatory process. We conclude that the anti-inflammatory properties of Lactobacillus plantarum LS/07 makes its suitable for the prevention or treatment of colitis.

Published: April 2018

Summary
To examine whether the presence of the rare A allele of the TNF-Alpha-308 G/A gene polymorphism is associated with erosive arthritis and rapid radiological progression of the disease.
The examined group included 131 patients with early RA. Using the PCR-RFLP method, the TNF-Alpha-308 G/A gene polymorphism was determined for all patients. In relation to the presence of the A allele of the examined polymorphism, the patients were divided into two subgroups: subgroup A (G/A and A/A genotypes) and subgroup G (G/G genotype). Based on the presence of the destructive changes in joints found in the initial radiographs, the findings were classified as erosive and non-erosive RA. Radiological progression was assessed on the basis of the annual change in the Larsen score – LS (0-200).
Group A comprised 62 (47.33%) patients, while group G comprised 69 (52.67%) patients. The presence of cysts and erosions in subgroups A and G was compared before the start of the methotrexate therapy. It was determined that erosions (erosive RA) were statistically significantly more frequent in group A (83.87% of patients) in comparison with group G (44.93% of patients), p < 0,001. Group A patients had a higher value of the Larsen score in relation to the group G both before and after methotrexate was administered for a year (before therapy, LS in group A: 48.58 ± 20.54; in group G 20.73 ± 12.31; p < 0.01; after MTX therapy, LS in group A: 58.32 ± 22.25; in group G 25.35 ± 14.57; p < 0.001). The average value of the annual LS change in group A was statistically significantly greater than the change in group G patients (9.98 ± 4.95 to 5.23 ± 2.72) (p < 0.05).
The presence of the A allele of the TNF-Alpha-308 G/A gene polymorphism is associated with the occurrence of early erosive joint changes and more rapid radiological progression of the disease.

Published: April 2018

Summary
The formation of Co(II) ion complexes with reduced low-molar dextran (RLMD, Mw 5000 g/mol) was studied at the pH range from 7.0 to 13.5. The cobalt content in synthesized Co(II)-RLMD complexes was ~3–12% (AAS) and it generally increases with pH. Co(II)-RLMD complexes were characterized by UV-Vis spectrophotometry and FTIR spectroscopy. UV-Vis data for synthesized complexes indicate tetragonally distorted Oh coordination of Co(II) ions with O atoms from ligand. The presence of IR bands at 765 cm−1 and 910 cm−1 in Co(II)-RLMD complexes indicates the existence of α-(1→6)O-glycosidic bonds. The similarities in the γ(C–H) range of the IR spectra indicate that there is no difference in the conformation of the glucopyranose units in RLMD and Co(II)-RLMD complexes. The occurrence of water molecules in Co(II)-RLMD complexes was confirmed by FTIR spectroscopy of deuterated samples.
