Abstract
The 2014/2015 influenza epidemic season was characterized by the predominance of the H3N2 subtype. The presented study investigated the genetic and antigenic heterogeneity of the H3N2 strains collected in the Czech Republic from November 2014 to March 2015. Phylogenetic analysis of the representative H3 hemagglutinin sequences was performed and the glycosylation status and crucial antigenic mutations were compared relative to the 2014 and 2015 vaccine strains (A/Texas/50/2012 and A/Switzerland/9715293/2013) and visualized in the H3 crystal structure. The molecular data were further supplemented by hemagglutination-inhibition test (HIT) results on fifteen H3N2 2014/2015 strains by using the A/Texas/50/2012 (H3N2) and A/Switzerland/9715293/13 (H3N2) antisera. Our data on the Czech H3N2 viruses from the 2014/2015 epidemic season could supplement the reports of official authorities with data from a particular geographi-cal area.

Abstract
BACKGROUND A set of core diabetes indicators were identified in a clinical review of current evidence for the EUBIROD project. In order to allow accurate comparisons of diabetes indicators, a standardised currency for data storage and aggregation was required. We aimed to define a robust European data dictionary with appropriate clinical definitions that can be used to analyse diabetes outcomes and provide the foundation for data collection from existing electronic health records for diabetes. METHODS Existing clinical datasets used by 15 partner institutions across Europe were collated and common data items analysed for consistency in terms of recording, data definition and units of measurement. Where necessary, data mappings and algorithms were specified in order to allow partners to meet the standard definitions. A series of descriptive elements were created to document metadata for each data item, including recording, consistency, completeness and quality. RESULTS While datasets varied in terms of consistency, it was possible to create a common standard that could be used by all. The minimum dataset defined 53 data items that were classified according to their feasibility and validity. Mappings and standardised definitions were used to create an electronic directory for diabetes care, providing the foundation for the EUBIROD data analysis repository, also used to implement the diabetes registry and model of care for Cyprus. CONCLUSIONS The development of data dictionaries and standards can be used to improve the quality and comparability of health information. A data dictionary has been developed to be compatible with other existing data sources for diabetes, within and beyond Europe.

Abstract
Coupling between the lower and upper atmosphere, combined with loss of gas from the upper atmosphere to space, likely contributed to the thin, cold, dry atmosphere of modern Mars. To help understand ongoing ion loss to space, the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft made comprehensive measurements of the Mars upper atmosphere, ionosphere, and interactions with the Sun and solar wind during an interplanetary coronal mass ejection impact in March 2015. Responses include changes in the bow shock and magnetosheath, formation of widespread diffuse aurora, and enhancement of pick-up ions. Observations and models both show an enhancement in escape rate of ions to space during the event. Ion loss during solar events early in Mars history may have been a major contributor to the long-term evolution of the Mars atmosphere.

Abstract
The Mars Atmosphere and Volatile Evolution (MAVEN) mission, during the second of its Deep Dip campaigns, made comprehensive measurements of martian thermosphere and ionosphere composition, structure, and variability at altitudes down to ~130 kilometers in the subsolar region. This altitude range contains the diffusively separated upper atmosphere just above the well-mixed atmosphere, the layer of peak extreme ultraviolet heating and primary reservoir for atmospheric escape. In situ measurements of the upper atmosphere reveal previously unmeasured populations of neutral and charged particles, the homopause altitude at approximately 130 kilometers, and an unexpected level of variability both on an orbit-to-orbit basis and within individual orbits. These observations help constrain volatile escape processes controlled by thermosphere and ionosphere structure and variability.

Abstract
AbstractEpidemic outbreaks of avian influenza (AI) virus H5N1 have been frequently reported in Egypt during the last nine years. Here we investigate the involvement of AI H5N1 in outbreaks of acute respiratory disease that occurred in several commercial chicken farms in Egypt in 2011, and we describe to the pathology caused by the virus in the course of the outbreak.Twenty-one chicken farms with history of acute respiratory symptoms and high mortalities were screened for AI H5N1. Virus identification was based on hemagglutination inhibition test, and PCR detection and sequencing of the hemagglutinin and neuraminidase genes. Virus distribution was determined by immunohistochemical staining of AI antigens in organs of infected birds. Standard H&E staining was performed for histological examination of affected organs.Eighty-one % of the examined birds, representing 100% of the screened farms, were positive for AI H5N1 virus. Phylogenetic analysis of the hemagglutinin and neuraminidase genes of the isolated virus reveals its affiliation to clade 2.2.1. Viral antigens were localized in the endothelial cells of the heart, liver, lungs and skin, where pathological lesions including congestion, hemorrhages, multifocal inflammation and necrosis were concurrently observed. According to the pattern of the viral antigen and lesion distribution in the visceral organs, we suggest cardiovascular and circulatory failures as the probable cause of death during these outbreaks. In conclusion, the present study further confirms the epidemic status of AI H5N1 virus in Egypt and reveals the highly pathogenic nature of the local isolates.

Abstract
REASONS FOR PERFORMING STUDY Diffusion of local anaesthetic solution after a mid-pastern ring block has not been investigated. OBJECTIVES To demonstrate potential distribution of local anaesthetic solution following injection of radiodense contrast medium as performed for a mid-pastern ring block. STUDY DESIGN Experimental. METHODS Twelve mature horses were used. One and a half ml radiodense contrast medium was injected over the medial or lateral palmar digital nerve at the level of the proximal aspect of the ungular cartilages. A dorsal ring block was performed on the ipsilateral side, 1.5 cm proximal to the palpable palmar aspect of the proximal eminence of the middle phalanx, using 2 or 5 ml contrast medium. Both forelimbs were injected on 2 days (48 injections). Four standard radiographic views of the pastern were obtained immediately, 10 and 20 min after injections. Images were analysed subjectively and objectively. RESULTS After dorsal injections the contrast medium was distributed in a diffuse patch over the ipsilateral half of the proximal phalanx (PP), extending proximally over the half of the length of PP in all limbs (greatest proximal extension: 89.0% of the length of PP [from distal] after 2 ml, 94.2% after 5 ml). There was significant proximal diffusion in the first 10 min after injection and significant dorsal diffusion between all time points (P<0.01). There was significant positive association between injected volume and the proximal extension of the dorsal contrast patch (P = 0.01). The median dorsal diffusion was to the dorsal midline of PP; 5 ml contrast medium resulted in significantly greater dorsal diffusion than 2 ml (P<0.01). The dorsal and the palmar contrast patches did not merge. CONCLUSIONS Diffusion to the proximal aspect of P1 occurred even after injection of only 2 ml contrast medium. Fetlock region pain may be influenced by a mid-pastern ring block. Ethical animal research: Written consent had been obtained from a representative of the horses' owner prior to starting the study. SOURCE OF FUNDING None. Competing interests: None declared.

Abstract
Background SLCO1B1 polymorphisms are relevant in statin pharmacokinetics. Aim of this study was to investigate the genetic variability and haplotype profile of SLCO1B1 polymorphisms in Roma and Hungarian populations. Genotypes of 470 Roma and 442 Hungarian subjects for c.388A > G, c.521T > C and c.1498-1331T > C polymorphisms were determined by PCR-RFLP assay. Using these SNPs eight different haplotypes could be differentiated. Results Differences were found between Roma and Hungarians in SLCO1B1 388AA (24.5 vs. 45.5 %), GG (33.4 vs. 17.9 %) genotypes, AG + GG (75.5 vs. 54.5 %) carriers, in G allele frequency (0.545 vs. 0.362), respectively (p < 0.001). The most common SLCO1B1 haplotype was the ht8 (GTT) both in Roma (43.6 %) and in Hungarian (59.1 %) samples. The ht6 (GCT) was not present in Roma population samples Haplotype analyses showed striking differences between the Roma and Hungarian samples in ht4 (ATT, 37.2 % vs 20.8 %), ht5 (GCC, 1.15 % vs. 3.62 %) and ht8 (GTT, 43.6 % vs. 59.1 %) haplotypes (p < 0.01), respectively. Linkage disequilibrium analysis showed that the studied variants are in different linkage disequilibrium patterns depending on the ethnic origin. Conclusions Similarly to Caucasians the 388G is the minor allele in Hungarians, however, in Roma the 388A was found to be the minor allele contrary to Indians (India). The minor allele frequency of 521T > C and 1498-1331T > C SNPs are almost three times higher in Romas than in Indians (Singapore and Gujarati, respectively). Observed allele frequency for 1498-1331T > C polymorphism reflects the measured average European rates in Hungarians. The results can be applied in population specific treatment algorithms when developing effective programs for statin therapy.

Abstract
Variants in SLCO1B3 transporter are linked to disposition and uptake of drugs and show high degree of heterogeneity between populations. A total of 467 Roma and 448 Hungarian subjects were genotyped for SLCO1B3 c.334T>G and c.1683-5676A>G variant alleles by PCR-RFLP assay and direct sequencing. We found significant differences in the frequencies of homozygous variant genotypes of SLCO1B3 334GG (41.54% vs. 8.04%, p<0.001) and 1683-5676GG (0.43% vs. 2.01%, p=0.028) between Romas and Hungarians. A significantly increased prevalence was found in SLCO1B3 1683-5676G allele frequency in Hungarians compared to the Roma population (15.07% vs. 3.43%, p≤0.001). The frequency of SLCO1B3 334G allele was significantly increased in Roma population compared to Hungarians (70.56% vs. 52.23%, p=0.001). The LD values between the examined SNPs were 80 and 90 in Roma and in Hungarian samples, respectively. Our results highlight notable pharmacogenetic differences between Roma and Hungarian populations, which may have therapeutic implications.

Abstract
OBJECTIVE The goal of our study was to find an easy and suitable skin burn model for rabbits, to identify the temperature and contact time to reach a deep 2nd degree burn, and to find the best wound dressing fixation method. MATERIAL AND METHODS We used New Zealand male rabbits as experimental models. On a pilot study, with a copper device heated to temperatures between 43-48 Celsius degrees, the burn was inflicted using contact timesof 3, 4, 5, and 7 seconds. The burn depth was evaluated histological. Twenty-four rabbits were used to evaluate four dressing fixation methods: regular dressing with retention bandages; skin stapler; collars and body resin cast. RESULTS A 2nd degree deep burn was obtained at 43 degrees for 4 seconds. The retention elastic bandages were removed within hours and the skin staplers were removed with teeth leaving wounds on the skin. The collars were more successful but produced superficial neck lesions. The body resin casts were the most successful. CONCLUSIONS The best contention method was the bpdy resin cast.

Structural and morphometric comparison of the molar teeth in pre-eruptive developmental stage of PACAP-deficient and wild-type mice. J Mol Neurosci 2014; 54:331-41.

Abstract
Pituitary adenylate cyclase activating polypeptide (PACAP) is a pleiotropic neuropeptide with widespread distribution. It plays pivotal role in neuronal development. PACAP-immunoreactive fibers have been found in the tooth pulp, and recently, it has been shown that PACAP may also play a role in the regeneration of the periodontium after luxation injuries. However, there is no data about the effect of endogenous PACAP on tooth development. Ectodermal organogenesis including tooth development is regulated by different members of bone morphogenetic protein (BMP), fibroblast growth factor (FGF), hedgehog (HH), and Wnt families. There is also a growing evidence to support the hypothesis that PACAP interacts with sonic hedgehog (SHH) receptor (PTCH1) and its downstream target (Gli1) suggesting its role in tooth development. Therefore, our aim was to study molar tooth development in mice lacking endogenous PACAP. In this study morphometric, immunohistochemical and structural comparison of molar teeth in pre-eruptive developmental stage was performed on histological sections of 7-day-old wild-type and PACAP-deficient mice. Further structural analysis was carried out with Raman microscope. The morphometric comparison of the 7-day-old samples revealed that the dentin was significantly thinner in the molars of PACAP-deficient mice compared to wild-type animals. Raman spectra of the enamel in wild-type mice demonstrated higher diversity in secondary structure of enamel proteins. In the dentin of PACAP-deficient mice higher intracrystalline disordering in the hydroxyapatite molecular structure was found. We also obtained altered SHH, PTCH1 and Gli1 expression level in secretory ameloblasts of PACAP-deficient mice compared to wild-type littermates suggesting that PACAP might play an important role in molar tooth development and matrix mineralization involving influence on SHH signaling cascade.

Abstract
Periodontitis is a chronic inflammatory disease leading to alveolar bone destruction, and eventually tooth loss. In genetically or environmentally predisposed individuals periodontopathogenic bacteria trigger an inflammatory immune response where activated macrophages secrete inflammatory cytokines and T helper 17 cells produce interleukin-17, receptor activator of nuclear factor kappa B ligand (RANKL) and tumor necrosis factor-α. Inflammation and the production of RANKL, the key cytokine responsible for osteoclast activation, cause excessive activation of osteoclasts. This results in a decoupling between bone formation and resorption, leading to bone loss. As conventional treatment does not target the inflammatory response and osteoclast activation, its effectiveness is limited. Novel treatments are thus required if we are to cure this disease. Mesenchymal stem cells (MSCs), including those of dental origin, are potent immunomodulators and are known to be suitable for tissue regeneration. MSCs can inhibit the immune response by suppressing T cells, inducing regulatory T cells and converting dendritic cells and macrophages into a regulatory phenotype. Additionally, genetic modulation may enhance the therapeutic potential of MSCs. In the present review the authors describe the potential use of MSCs, either unmodified or engineered for therapeutic purposes in periodontitis, with special emphasis on MSCs from dental pulp and periodontal ligament. The paper envisions that multiple targeting of this inflammatory disease by modulating the immune response, promoting bone regeneration and inhibiting bone resorption might yield significantly improved treatment outcomes when combined with conventional treatment modalities.
