In human medicine, these conditions are widely described (Weingart et al ., 2000), mostly for insurance issues related to hospitalization, while in veterinary medicine are reported only occasional case reports. 4155 clinical records related to cattle admitted to the Clinic for Ruminants and Swine of the University of Milan between 2005 and 2017 were analyzed. Clinical cases that required admission because of an iatrogenic related disease were selected for this study. For case selection, 3 experienced veterinarians examined the clinical records, cross-compared the selection and pick 114 cases (2,7%). The iatrogenic diseases were primarily caused by farmers (93%) than veterinary practitioner (7%). Iatrogenic diseases were caused mostly by erroneous administration of drugs (47,4%), excessive traction at birth (17,5%), improper milk or colostrum administration, frequently performed by oroesophageal tubing (16,7%) or by forced administration using a nipple bottle (12,3%). As verified by our study, farmers often performs medical, nursing and zootechnical procedures without adequate competences and sometimes choose medical treatment for sick animals without professional consultation of veterinarians.The veterinarian rule is fundamental in farmer education. Clinicians, especially in some professional branches as neonatology, should be more responsible of their assignments, avoiding delegation of specific procedures to unskilled staff. The importance of communication in improving management and health in dairy farms has been recently demonstrated (Jansen and Lam, 2012; Jansen et al ., 2010). Effective communication has a key role in dairy herd health and communication strategies are required to support diseases control programs (Lievaart et al ., 2008). More attention to iatrogenic issue may have a positive impact on animal and public health. Moreover, a decrease of unnecessary and injurious drug administration may result in a reduction of treatment costs and in prevention of antibiotic resistance.","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89582608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to determine the accuracy of D­Heart® compared with the gold standard non­portable 6­lead electrocardiograph in the evaluation of cardiac rhythm in dogs. Standard 6­lead and D­Heart® ECGs were acquired in conscious dogs. Concordance between methods was assessed by weighted k Cohen index, with its relative significance, taking as end point variable standard 6­lead ECG group. Bland ­ Altman method (95% confidence level) was applied for P, PR, QRS, T and QT. Since differences didn’t follow a normal distribution, a non­parametric approach was used to determine limits of agreement. P was significant when < 0.05 (Maurizi et al . 2017). Amplitude of waves was not considered because currently the software doesn’t allow voltage variation. 115 dogs of different weights and breeds admitted to the Cardiology Service of DIMEVET were enrolled. Mean age was 7,5±4 years. Most were intact males (45%, n=51). The most represented breed was mongrel (27%, n=32). Weighted Cohen's kappa test demonstrated excellent concordance in the evaluation of the heart rhythm (0.989, p<0.001), for ST segment morphology (0.991, p<0,001) and for T wave morphology (0.838, p=0.040). There was a 100% concordance in P morphology determination. P, PR, QRS, T and QT intervals comparison with Bland­Altman showed an extremely good concordance for D­Heart® measurements (95% limit of agreement ±0.9 ms for P, ±10 ms for PR, ±35 ms for QRS, ±5 ms for T wave). Less concordance resulted for QT (±80 ms). In Conclusion, D­Heart® proved effective accurate recording of ECG comparable to standard 6­lead electrocardiographs, opening new perspectives to improve diagnostic tools in veterinary cardiology. Future perspective will be the development of a telecardiology network and to improve arrhythmia’s diagnosis in small animal practice (Bruining et al ., 2014; Haberman et al ., 2015).","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79021329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To pore over the mechanisms leading to the biofilm formation on metallic implants, in the present study, we carried out the phenotypic and genotypic characterization of the clinical isolate S. epidermidis GOI1153754-03-14. Materials and Methods: The antimicrobial susceptibility and minimum inhibitory concentration (MIC) of the strain were evaluated through the Vitek2 System (Biomerieux), as well as its ability to form biofilm in vitro through a spectrophotometric assay (Stepanovich, 2000). The genomic DNA was extracted by Bacterial Genomic DNA Isolation Kit (Norgen Biotek Corp.). Libraries were prepared with the ThruPLEX DNA-seq (Rubicon Genomics) and then sequenced on the Illumina MiSeq platform through the MiSeq Reagent Kit v3 (600-cycles) to produce 300 bp paired-end reads (Illumina Inc.). Reads were quality-trimmed and gene annotated thanks to the RAST software (Aziz, 2008). Results: The antimicrobial susceptibility along with the MIC values are reported in Table 1. The outputs resulted in 51 contigs (Average = 50,720.6 Mb) with 396X fold average coverage. The total genome is 2,586,753 bp long with a GC content of 31.84% and an N50 value of 7 bp. The whole genome is composed by 2,467 protein-encoding genes and 64 RNAs (55 tRNAs and 9 rRNAs). The entire genome sequence has been deposited in the European Nucleotide Archive (ENA) under the accession no. FWCG01000000 (Bottagisio, 2017). Discussion: The genotypic and phenotypic characterization of the S. epidermidis GOI1153754-03-14 will enable a better comprehension of the mechanisms involved in the biofilm formation on orthopedic implants paving the way for innovative preventative and therapeutic strategies. Moreover, the sequence of this clinical strain is mandatory to develop dedicated proteomics analysis in order to highlight functional mechanism of biofilm formation.","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86089268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aims of the present study were: the validation of two commercially available clones of polyclonal anti-human FXR1 antibody in dogs; their application to investigate FXR1 expression in a group of canine oral melanomas. Anti-FXR1 antibody was not previously validated in the canine species. Two different commercially available polyclonal anti-FXR1 antibodies (respectively made in goat and in rabbit) were used. FXR1 protein in canine serum was identified by western blot after SDS-PAGE, using human serum as control. FXR1 immunohistochemical expression was tested in a series of normal tissues, that are expected to express FXR1, and in 31 cases of oral melanomas. The final immunohistochemical protocol used heat-induced unmasking and overnight incubation. FXR1 protein bands in canine serum were detected by tested antibodies, in a more specific way by the rabbit antibody. FXR1 immunohistochemical staining was positive in all tested organs, with different levels of expression. FXR1 was also expressed in 31/31 tested melanomas, with variable intensity and percentage of positive cells (Figure 1). Equal results were achieved with the two antibodies in 8 cases of melanoma, whereas there were variable differences in 22, and one case stained only with goat antibody. The rabbit antibody gave less background staining. This study validated anti-FXR1 antibodies for use in the canine species. This protein was expressed in various normal tissues, as well as in the tested neoplasms. Significance of different level of expression is undergoing evaluation with further studies.","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73472645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the small molecule 5-azacytidine (5-aza-CR) has been shown to induce a transient higher plasticity state in adult somatic cells, grown in standard 2D conditions. Recent evidence have also shown the possibility to regulate and maintain cell pluripotency through the use of 3D culture systems. In the experiments here presented, we combine the two approaches and investigate whether the simultaneous use of a 3D micro-bioreactor and 5-aza-CR is able to promote cell rearrangement, boost the induction of high plasticity and stably maintain it. To this purpose, fibroblasts were either plated on plastic dishes (2D) or encapsulated in a Liquid Marble (LM) micro-bioreactor (polytetrafluoroethylene (PTFE)), which has been previously shown to support the growth of living microorganisms, tumor spheroids, fibroblasts, red blood cells, and embryonic stem cells (Ledda et al., 2016). Cells were then erased with 5-aza-CR, for 18 hours and cultured in Embryonic Stem Cell (ESC) medium for up to 28 days. Morphological analysis and pluripotency related gene expression levels were monitored for the entire length of the experiments. 2D cells, kept a monolayer pattern and acquired a pluripotent state that was, however, transient and lost by day 6. In contrast the use of a 3D system maintained and stabilized the high plasticity state in LM cells until the end of the experiments (Fig. 1).  The data obtained demonstrate that cell rearrangement and interactions may modulate 5-aza-CR induced plasticity and suggest a correlation between 3D mechano-transduction-related pathways and  epigenetic regulation of cell phenotype.","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82701923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, the present research aims at analyze the dynamics of the value in the local non-existent supply chain of the large wild game meat by the application on the case study of the Valle Ossola (Piedmont, Italy). Due to its representativeness among Italian wild ungulates, the research focus on red deer meat. The data has been collected in 2016 through in-depth interviews and focus groups with the stakeholders involved in the supply chain: hunters, transformers and restaurateurs. Results show that for the hunter the red deer reach a hypothetical price of 6,00 €/kg. From a meat processing targeted at the maximum enhancement of the carcass, without any waste, the transformers can reach a hypothetical price of 9,80 €/kg. Whereas for the restaurateur, the red deer meat can reach a final price range between 22,88 and 51,47 €/kg (hypothesizing maximum sales of high value-added course). Through the maximization of the meat’s quality, hunter and transformers profits can increase significantly, with a redistribution of the added value throughout the supply chain. A limitation of this study is that the calculated values does not take into consideration the stakeholders’ production costs (that increasing along the supply chain). Considering our findings, the development of sustainable supply chain of the local game meat could be economically interesting. Thus, wild ungulates could represent an economic resource for the population rather than an environmental and social cost for the mountain areas.","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84899510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the present understanding of many biological processes is mainly based on two-dimensional (2-D) systems that typically provides a static environment. In the present study, we tested two different 3-D culture systems and apply them to the epigenetic conversion of mouse dermal fibroblasts into insulin producing-cells (Pennarossa, et al. , 2013; Brevini, et al ., 2015), combining also the use of two oxygen tensions. In particular, cells were differentiated using the Polytetrafluoroethylene micro-bioreactor (PTFE) and the Polyacrylamide (PAA) gels with different stiffness (1 kPa; 4 kPa), maintained either in the standard 20% or in the more physiological 5% oxygen tensions. Standard differentiation performed on plastic substrates was assessed as a control. Cell morphology (Fig.1A), insulin expression and release were analyzed to evaluate the role of both stiffness and oxygen tension in the process. The results obtained showed that 1 kPa PAA gel and PTFE system induced a significantly higher insulin expression and release than plastic and 4 kPa PAA gel, especially in low oxygen condition (Fig.1B). Furthermore, comparing the efficiency of the two systems tested, 1 kPa PAA gel ensured a higher insulin transcription than PTFE (Fig.1C). Recent studies show the direct influence of substrates on lineage commitment and cell differentiation (Engler, et al ., 2006; Evans, et al ., 2009). The evidence here presented confirm that the use of an appropriate stiffness (similar to the pancreatic tissue), combined with a physiological oxygen tension, promote β-cell differentiation, with beneficial effects on cell functional activity and insulin release. The present results highlight the importance of 3-D cell rearrangement and oxigen tension to promote in vitro epigenetic conversion of mouse fibroblasts into insulin-producing cells.","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77592200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is probably due to the standardization of several peculiar morphological characteristics that have always been one of the major exclusion criteria of individuals from selection. Among these, ear carriage is one of the most ancient and considered a signature of domestication in several species, such as the dog, pig, sheep and goat (Boyko et al., 2010). The availability of improved genomic analyses tools for goats may provide useful information on genes involved in this trait. By studying, for example, the homozygosity decay of haplotypes (contiguous length of alleles) such information can be detected. In the current study, we focused on the Maltese goat, a breed showing floppy ears, in comparison with other Italian breeds using a goat medium density SNP chip (Nicoloso et al., 2015). A total 48,767 SNP markers for 369 animals belonging to 16 breeds or populations were analyzed. Genotypes were imputed within population excluding markers without known position on the current genome assembly (ARS1, Bickhart et al., 2017). Population analysis using MDS, ADMIXTURE and fastSTRUCTURE confirmed the good differentiation among the populations. Integrated Haplotype Score (iHS, Sabeti et al., 2007) was performed for each population, comparing the regions detected on the Maltese breed with the others considered to detect genes that may be involved into shaping  ear morphology. These results may provide new insights into ear carriage phenotype by detecting genes that play a pivotal role in shaping the goat phenotypic diversity.

The aim of this study is to validate a paraoxon-based method to measure PON-1 and to establish reference intervals (RIs) in healthy horses and foals. 120 horses (40 geldings, 40 stallions, 40 mares; median age: 11 years; 57 Warmbloods, 46 Trotters) and 55 foals (27 females, 28 males; median age: 47 days; 22 Warmbloods, 31 Trotters) considered healthy after physical examination and biochemistry were examined. Horses were grouped by breed: Thoroughbreds, Trotters, Warmbloods, Draft horses and Ponies. Serum PON-1 was measured with an automated spectrophotometer and an enzymatic method validated in other species ( Giordano et al., 2013). After the analytical validation (precision, accuracy, interference studies), RIs were determined using the Reference Value Advisor software, according to ASCVP guidelines ( Friedrichs et al., 2012 ). The possible gender-, age- and breed-related differences were statistically investigated. The paraoxon-based method was precise (CVs <4.0%) and accurate (P<0.001 in linearity under dilution and spike-recovery testing) but is affected by interference from mild bilirubinemia, severe lipemia or hemoglobinemia. The RIs recorded in the whole population was 38.1-80.8 U/mL. According to the Harris and Boyd test, separate RIs are recommended only for adult females and for Warmblood and Trotter adults (Figure 1). This study demonstrated that analytical performances of the paraoxon-based method for measurement of PON-1 in horses are acceptable. PON-1 is lower in horses than in other species. If future studies will demonstrate that oxidative stress induces a significant decrease of PON-1, this results will be useful to correctly classify healthy and sick horses; PON-1 could be used, as in human medicine, as a marker of oxidative stress.","PeriodicalId":14105,"journal":{"name":"International Journal of Health, Animal science and Food safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83552962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
