Authors: Murdjeva Mariana A. , Ryasheva Nadezhda P. , Draganov Marian M. , Paunov Lyubomir D. 
Published: April 2013

ABSTRACT
INTRODUCTION: Several immunological methods are used to determine the serum antinuclear antibodies (ANA). Indirect immunofl uorescence assay (IFA) with tissue slices or HEp-2 cells is the standard technique considered the gold standard for their screening. Serumfree McCoy-Plovdiv cell line may also be used as substrate for IFA. Another method for detection of total and specifi c ANA is the enzyme-linked immunosorbent assay (ELISA). Immunoblot is also applied in specifi c ANA confi rmation.
The AIM of the current study was to determine and propose a justifi ed immunological approach for identifi cation of clinically signifi cant ANA by comparing the screening tests - ANA-IFA on serum-free McCoy-Plovdiv cell substrate with ELISA for total ANA, and confi rmative methods for specifi c ANA-ELISA with immunoblot.
MATERIALS AND METHODS: Serum samples from 38 patients screened for total ANA by ELISA (Trinity Biotech, NY, USA) and IFA-ANA with МcCoy-Plovdiv cell line, were included in the study. Positive samples were confi rmed by immunoblot (Orgentec Diagnostika, Germany) and ELISA for specifi city of confi rmed ANA.
RESULTS: No significant difference (Р > 0.05) and very good agreement were found between the two screening tests. Very good agreement for specifi c antibodies against SS-A, SS-B, dsDNA, moderate for anti-Sm and anti-Sm/RNP and fair for anti-histone/nucleosomal antibodies was found between confi rmative methods. No agreement was found for anti-Scl-70 antibodies.
CONCLUSION: IFA-ANA with serum-free МcCoy-Plovdiv cell line and screening ELISA may be recommended for determination of total ANA, and immunoblot and ELISA - for confi rmation and identifi cation of specifi c ANA.

Published: April 2013

ABSTRACT
AIM: The aim of the present study was to measure macular thickness in healthy eyes and find whether it changes with age.
MATERIAL AND METHODS: We examined 163 healthy eyes of 84 healthy volunteers. In order to measure their macular thickness the patients were examined using spectral-domain optical coherent tomography (SD-ОСТ - iVue, Optovue). They were allocated into 6 age groups.
RESULTS: The mean central macular thickness (inner circle - fovea centralis) was 248.9 ± 17.9 μm (mean ± SD), and the mean total macular thickness (an area including 9 subfields as defined by ETDRS) was 286.2 ± 13.9 μm (mean ± SD). We found that it correlated negatively with age (r = - 0.18; p = 0.03; Pearson correlation).
CONCLUSION: We found a statistically significant decrease of mean macular thickness as age increased.

Authors: Siddiqui Zamin S. 
Published: April 2013

Abstract
The effects of double stress environment i.e. lead (heavy metal) and NaCl (saline) on the activity of antioxidant enzymes in Vigna radiata seedling were studied. The antioxidant activities of enzymes, i.e of superoxide dismutase, catalase, ascorbate peroxidase, guaiacol peroxidase, glutathione reductase and their activity proportions were examined. Superoxide dismutase, ascorbate peroxidase, guaiacol peroxidase and glutathione reductase activities were substantially increased in a combined stress environment as compared to catalase. Further, in comparison with catalase and ascorbate peroxidase, glutathione reductase showed increased activities together with superoxide dismutase in a combined stress environment. Superoxide dismutase and glutathione reductase showed higher activity proportion in combined treatment. Physiological role of these enzymes in stress tolerance mechanism is discussed.
Heaths with dwarf ericaceous shrubs and Alpine juniper (Juniperus alpina) in the Dinaric Alps: A nomenclatorial and synsystematic re-appraisal
Authors: Surina Boštjan 
Published: April 2013

Abstract
The ecology and phytosociology of north-western Dinaric heaths of the association Rhododendro hirsuti-Juniperetum alpinae Horvat ex Horvat et al. 1974 nom. corr. prop. as well as the syndynamics and synsystematics of heaths in the Dinaric Alps are discussed. While the structure (physiognomy) of these stands is very homogenous and dominated by few species, the flora is heterogeneous, since ecotonal areas, where heaths are most frequently developed, represent a contact zone of elements of different syntaxa. Due to an abrupt reduction in pasture activities strong encroachments of shrubs and trees have become common, which additionally contribute to the floristic heterogeneity of the heaths. Although the identification and circumscription together with synecology and synchorology of heaths in general are more or less easily understood and straightforward, their floristic affinities, in relation to structure homogeneity and syndynamics, are complicated, which led to the proposal of several synsystematic schemes depending on interpretation of the relationship between flora and structure of stands. Dinaric heaths are classified into three classes, Erico-Pinetea, Vaccinio-Piceetea and Festuco-Brometea and a classification scheme is proposed together with nomenclatorial revision of the analyzed heaths with dwarf ericaceous shrubs and Alpine juniper (Juniperus alpina) in the Dinaric Alps

Published: April 2013

Abstract
Ecological gradients along river banks of the Mura River influence forest species composition. On the basis of 58 relevés of floodplain forests along theMura River, the classification of vegetation plots was performed with the Pc-Ord program. The diagnostic species combination for three clusters revealed after classification was calculated by fidelity measure (phi-coefficient) and presented in an analytic table. Average Ellenberg inidicator values, stream distances and relative elevations of the relevés were passively projected onto PCA to show ecological relationships among them. Correlations of plant functional type and stream distance gradients were calculated with regression analysis. For themain edifiers response curves to the stream distance gradients weremade. The classification of the Mura floodplain forests has revealed three ecologically interpretable vegetation types: Salicetum albae (most humid and nutrient-rich sites), Fraxino- -Ulmetum allietosum ursini (ecologically intermediate sites), F.-U. quercetosum robori (the driest and the least nutrient-rich sites). Zonation of vegetation is connected to distance from the closest stream which influences species distribution through ecological gradients of moisture and nutrient. The proportion of therophytes is significantly negatively correlated with the distance from the closest stream and the proportion of neophytes is significantly negatively correlated with distance from the main stream.

Published: April 2013

Abstract
So far 24 species of terrestrial small mammals are known from Făgăraş Piedmont, one of them (Chionomys nivalis) requiring further confirmation, as its presence at this elevation is put under question by the authors. In 2010 and 2011 three field campaigns were carried out in Făgăraş Piedmont, which targeted the abundance and structure of terrestrial small mammal communities in different habitats from three localities, using the capture-mark-release method. 61 transects of traps were installed in 9 types of habitats. 491 small mammals were captured belonging to 14 species, three shrews and 11 rodents. The highest densities were recorded in cultures and unused land, but specific diversity is not correlated with abundance.

Abstract
This work aims to evaluate Sustainable Land-use Management (SLM) through bio-physics elements (productivity, security and protection) and socio-economic elements (economic viability and social acceptability). The investigated area, 27000 hectares, lies between 31O15² and 32O 00² E and latitudes 31O30² and 30O00² N. To assess SLM, geomorphology and associated soils were identified, the land degradation processes were recognized, then a Sustainable Land use Management Spatial Model (SLMSM) was built and used to assess the sustainable land use management in the study area. The area included three landscapes; fluvio-lacustrine plain, marine plain and flood plain. Four SLM classes were outlined; the relatively high decantation basins representing 62.4% of the agricultural area, the relatively low decantation basins (Class II) occupying 22.5% of the agricultural area, overflow basins (Class III) covering 9.5% of the agricultural area, and Class IV that found in clay flats, sandy remnants, overflow mantle and river terraces occupying 5.6% of the agricultural area.

Published: April 2013

Abstract
Technogenic soils (Technosols) developed from mine tailings containing iron sulfides occurring in the area of the abandoned .Siersza. hard coal mine in Trzebinia and the abandoned .Staszic. pyrite mine in Rudki were investigated in order to assess their properties. The study revealed that the most adverse properties of the technogenic soils investigated are: strong acidity (pH below 3), the presence of large amounts of rock fragments containing unweathered sulfides, as well as the occurrence of heavy metals (e.g. Pb, As, and Tl) and radioactive elements (U and Th). All these properties should be taken into account during management of the studied mine tailings.

Authors: Bjekić Milan D. 
Published: April 2013

Abstract
Hand, foot and mouth disease is a systemic infection caused by enteroviruses. It is highly contagious, spreads by direct contact, and is commonly seen in young children. The disease is characterized by ulcerative oral lesions and a vesicular rash on palms, soles and characteristically between the fingers and toes, associated with mild systemic symptoms and signs such as fever and lymphadenopathy.
We present a 35-year-old man referred to a dermatologist with mouth lesions and skin rash. The patient had a fever, followed by a sore throat and malaise, which occurred two days before the rash. Physical examination revealed numerous superficial erosions and small vesicular lesions on the lower lip mucous membrane and on the hard palate, and also, multiple, discrete small vesicular lesions on fingers and toes. The patient was treated symptomatically and all the lesions resolved completely in a week. Adults with hand, foot and mouth disease usually experience milder symptoms than children. In conclusion: the disease should not be overlooked in middle-aged adults with a vesicular rash.
Highs and lows of the resortification of the Saint-Paul coast (Reunion Island)
Authors: Jauze Jean-Michel 
Published: April 2013

Abstract
Reunion has few white sand beaches. The most exploitable of them are on the Saint-Paul coast on the west of the island, which are currently in the news after a spate of shark attacks. Their development for tourism has turned Saint-Gilles, once a small fishing and farming village, into a local and international beach resort with extensive repercussions on the organization of the municipal territory in which the agricultural uplands of the hinterland occupied an important area. This article analyses the imbalances created by such development and its sustainability conditions.

Abstract
In this paper results of influence of building-installation system parameters on value of energetic coefficients were calculated. Three types of buildings (standard, energy saving and low energy) with heating surface of 100, 150 i 200 m2 were used. The above types of buildings differ on thermal barrier and heating system efficiency. The influence of the gravity and mechanical ventilation systems on the final heat energy of different kinds of houses was shown. Parameters of the certificate for energy characteristics of building were used. Mathematics models of influence of thermal barrier parameters and heating surface on the value of energy characteristics, namely final energy EF, primary energy EP and useful energy EU were established. Influence of such parameters as heating energy factors, ventilation system and energy sources on the energy efficiency improvement of buildings was analyzed. The building environmental assessment system was proposed on the base of energetic and ecological analysis of houses.

Published: April 2013

Abstract
Boreholes cementing operations at the depth of several kilometers requires the best technology as well as the best materials. To produce the materials satisfying all the requirements concerning the tamping works is possible using the technology of dry building mixes (DBM) prepared at the factories by thorough mixing of accurately dosed components. Using of chemical admixtures allows improving some properties of these mixes. In this work the influence of mineral fillers and chemical admixtures on the properties of the fresh mixture and hardened tamping mortar was investigated. It is established that introduction of the admixture with complex action on the basis of stabilizer Walocel 15-01 and plasticizer Melflux 2651 allows obtaining the fresh mixture with high spreadability. At the same time the value of dehydration approaches to zero which favorably effects on stabilization of fresh mixture and not allows the sedimentation processes to take place. By the X-ray analysis, the positive influence of modification admixtures on the hydration processes in the tamping mortars by activating them was identified. In the result of this, the formation of hydrate phases is accelerated; these phases tightly mud the pore area of tamping stone increasing by this its strength.

Published: April 2013

Abstract
- Zoltán Igmándy (1925-2000), prominent Hungarian mycologist, worked as professor of forest protection at the University of West-Hungary Sopron. His main research area was the investigation of wood-inhabiting poroid fungi of Hungary, their occurrence and importance in forest pathology and wood protection. During his 40 years of scientific activity Igmándy created a rich fungal collection (herbarium Z. Igmándy) which includes the complete polypore mycota known to occur in Hungary until 1990. The paper provides a brief compendium of the collection, a list of species characterised by the number of specimens, number of sampling locations and enumeration of the hosts and substrata of the specimens.
Photodegradation of Timber of Three Hardwood Species Caused by Different Light Sources
Authors: Tolvaj László , Varga Dénes 
Published: April 2013

Abstract
- In this study, resistance of black locust, beech and poplar wood to photodegradation was tested, applying sunlight, a xenon lamp and a mercury vapour lamp. The irradiation time was 200 hours for sunlight and the xenon light and 20 hours for the mercury light. The changes were monitored by colour measurements and infrared spectroscopy. The colour change of black locust was more intensive at the beginning of the irradiation than that of the beech and poplar. The degradation of aromatic structure of lignin (absorbing at 1510 and 1596 cm-1) in black locust was minor compared to the same changes of beech and poplar during the first 10 hours. The mercury lamp induced more intensive changes both in colour and in infrared spectrum than the other two light sources. The results show that the high extractive content of black locust absorbs a considerable amount of light radiation protecting the main chemical components of wood.

Published: April 2013

Abstract
As being the most debated polygenic disease, rheumatoid arthritis elicits great interest in the study of association with genetic factors in various ethnic and racial groups. Some of the HLA-DRB1 alleles are encoding shared epitope amino acids that are not conferring the same risk in various populations. Our study focuses on the evaluation of the distribution of HLA-DRB1 alleles in Romanian patients with early rheumatoid arthritis, along with controls by using PCRSSP method. HLA-DRB1 allele genotyping showed statistically significant differences given by a higher allele frequency for *04, *01 and *14. Also, in our study was observed a lower frequency for *03,*11,*13 and *15 HLA-DRB1 allele in patients group compared with controls, also a high frequency for *0404 and *0408 allele, in contrast with *0401 and *0402 which were significantly lower in patients than in controls. *0403, *0405 and *10 were not associated with early rheumatoid arthritis in our group diagnosed according with new classification criteria ACR/EULAR 2010. In present study we found a negative association of *0402, *11 and *13 with early rheumatoid arthritis. Results of our study are demonstrating the need of a continuous work of allele tracing and associating with rheumatoid arthritis, especially in cases early diagnosed in order to create sufficient premises for instituting a correct and possibly long term remissive treatment.

Published: April 2013

Abstract
In the present study we have determined some characteristics (aspect, odor, solubility, emulsion type, water and volatile substances content, total fatty matter, saponification index, ester index) for three pharmaceutical ointments belonging to the group of non-steroidal anti-inflammatory: Diclac, Ketonal, Indometacin and one antibiotic ointment for ophthalmic use: Ophtagram. In order to achieve stability study of studied ointments, the pH, the acidity index, the peroxide index and the iodine index were determined over a year every three months. After 9 months from the opening of the tubes, analytical determinations have shown that pH values, acidity, peroxide and iodine indexes no longer fit to the values recommended for medical use, which confirms the directions available on the package.

Published: April 2013

AbstractThe synthesis and characterization of MCM-41 supported Co-Mo catalysts and catalytic hydrogenation of 1-octene to n-octane were discussed. BET specific surface area of MCM-41, calculated from N2 adsorption/desorption isotherm, was 1690 m2/g. The XRD patterns of the Co-Mo/MCM-41 catalysts show that metal species are finely dispersed and the size of CoO and MoO3 particles is below the detection limit by XRD. The 1-octene hydrogenation activity of the catalysts decreased with increasing the Co content up to 9 wt.% for the Co-promoted Co-Mo/MCM-41 catalysts with a MoO3 content of 12 wt.%. All the catalysts show increased hydrogenation activity with increasing reaction temperature in the temperature range from 200 to 350°C.

AbstractThis study was carried out in the Rajghat reservoir has been used as a drinking water resources from last decades. The aim was to investigate the temporal and spatial variability of water quality. Data investigation was processed using multivariate analysis. Samples were taken in 05 stations spreading out over the water body during three seasons were analyzed for their physicochemical characteristics in order to explore the contamination of reservoir water samples, using Correlation analysis, multiregression analysis and modeling. On comparing the results against BIS water quality standards, it is found that some of the water samples are polluted. A systematic calculation of correlation coefficient between water quality parameters has been done with the objective of minimizing the complexity and dimensionality of large set of data. An attempt has been made to find the seasonal quality of water in reservoir, in order to adopt a statistical model for examine water quality. The results of this study are believed to be valuable to help water resources managers understand complex nature of water quality issues and determine the priorities to improve water quality.
