    Caseins are widely used for species identification of dairy products. Isoelectric focusing (IEF) of para-κ-casein peptide is used as the official German method for the differentiation between caprine (isoform A) and ovine (isoform B) dairy products, based on their different isoelectric points. The discrimination between Greek goat and ewe dairy products using IEF has, however, been shown to be problematic because of the existence of the ewe isoform in milk from Greek indigenous dairy goats. This could be due to nucleotide polymorphisms within the goat κ-casein gene of Greek indigenous breeds, which alter the isoelectric point of the para-κ-casein peptide and lead to false positive results. Previous DNA analysis of the goat κ-casein gene has shown high levels of polymorphism; however, no such information is available for Greek indigenous dairy goats. Therefore, 87 indigenous dairy goats were sequenced at exon IV of κ-casein gene. In total, 9 polymorphic sites were detected. Three nonsynonymous point mutations were identified, which change the isoelectric point of the goat para-κ-casein peptide so that it appears identical to that of the ewe peptide. Ten composite genotypes were reconstructed and 6 of them included the problematic point mutations. For the verification of genetic results, IEF was carried out. Both goat and ewe patterns appeared in the problematic genotypes. The frequency of these genotypes could be characterized as moderate (0.23) to high (0.60) within Greek indigenous breeds. However, this is not an issue restricted to Greece, as such genotypes have been detected in various non-Greek goat breeds. In conclusion, IEF based on the official German method is certainly inappropriate for ovine and caprine discrimination concerning Greek dairy goat products, and consequently a new method should be established.

    The objective of the present study was to evaluate whether immunosuppression occurs in 3 different Greek dairy sheep breeds during the periparturient period. A total of 33 ewes from 3 breeds [i.e., the low-producing Boutsiko breed (n = 11), which is highly adaptable to harsh environments; the high-producing but environmentally fragile Chios breed (n = 11); and an intermediate synthetic breed (50% Boutsiko, 25% Arta, and 25% Chios, n = 11)] were used. Blood samples were collected at 18 and 2 d before parturition and at 15 d after parturition. Total cell-associated and membrane-bound urokinase plasminogen activator (U-PA) activity, free U-PA binding sites on cellular membranes, and superoxide anion (SA) production by activated phagocytes were determined. Results indicated that all immune parameters measured remained constant during the periparturient period for the Boutsiko breed. In contrast, there were reductions in total cell-associated and membrane-bound U-PA activity by both monocytes-macrophages and neutrophils and in SA production by monocytes-macrophages at d 2 before parturition for the Chios breed. In the synthetic breed, there were reductions in total cell-associated and membrane-bound U-PA activity by monocytes-macrophages and in SA production by both monocytes-macrophages and neutrophils at d 15 after parturition. Thus, mild immunosuppression during the periparturient period was observed in the 2 breeds with the highest milk production.

    Between 2007 and 2009, the largest human Q fever epidemic ever described occurred in the Netherlands. The source was traced back to dairy goat farms, where abortion storms had been observed since 2005. Since one putative cause of these abortion storms is the intensive husbandry systems in which the goats are kept, the objective of this study was to assess whether these could be explained by herd size, reproductive pattern and other demographic aspects of Dutch dairy goat herds alone. We adapted an existing, fully parameterized simulation model for Q fever transmission in French dairy cattle herds to represent the demographics typical for Dutch dairy goat herds. The original model represents the infection dynamics in a herd of 50 dairy cows after introduction of a single infected animal; the adapted model has 770 dairy goats. For a full comparison, herds of 770 cows and 50 goats were also modeled. The effects of herd size and goat versus cattle demographics on the probability of and time to extinction of the infection, environmental bacterial load and abortion rate were studied by simulation. The abortion storms could not be fully explained by demographics alone. Adequate data were lacking at the moment to attribute the difference to characteristics of the pathogen, host, within-herd environment, or a combination thereof. The probability of extinction was higher in goat herds than in cattle herds of the same size. The environmental contamination was highest within cattle herds, which may be taken into account when enlarging cattle farming systems.

    Full Text Available Primate erythroparvovirus 1 (parvovirus B19 is a member of the Erythrovirus genus of the Parvoviridae family and it is one of the few members of the family known to be pathogenic in human. B19 infection is common and widespread with the virus being associated with numerous rheumatologic and haematologic manifestations. More specifically, maternal infection with parvovirus B19 during pregnancy can cause severe anemia which may lead to nonimmune hydrops or fetal demise, as a result of fetal erythroid progenitor cells infection with shortened half-life of erythrocytes. We present a rare case reported in the Greek population, of subclinical transient reticulocytopenia due to B19 parvovirus infection, in an asymptomatic pregnant woman, without medical history of hemoglobinopathy, and with the presence of hydrops fetalis during the third trimester of her pregnancy.

    Full Text Available Abstract Background Toxoplasma gondii is a major problem for the sheep industry as it may cause reproduction problems. The importance of T. gondii in Norwegian goat herds is uncertain, but outbreaks of toxoplasmosis in dairy goat farms have been recorded. The aim of this study was to describe the prevalence of T. gondii infection in Norwegian dairy goats by using serology. Findings Goat serum originally collected as part of two nationwide surveillance and control programmes between 2002 and 2008 were examined for T. gondii antibodies by using direct agglutination test. In total, 55 of 73 herds (75% had one or more serologically positive animals, while 377 of 2188 (17% of the individual samples tested positive for T. gondii antibodies. Conclusions This is the first prevalence study of T. gondii infection in Norwegian goats. The results show that Norwegian goat herds are commonly exposed to T. gondii. Nevertheless, the majority of goat herds have a low prevalence of antibody positive animals, which make them vulnerable to infections with T. gondii during the gestation period.

    Full Text Available The frequencies of HLA antigens in 33 HIV seronegative and in 88 HIV seropositive haemophiliacs, who have been followed for at least 6 years since seroconversion or first HIV positive test. were evaluated in relation to disease susceptibility and disease progression. A high frequency of HLA-A2 and -DR2 antigens and a low frequency of HLA-A9 were found to characterize HIV seropositive patients (p<0.05. Progressors to symptomatic CDC stage IV had a higher frequency of HLA-A9 (p<0.01 and DR3. Rapid decline of CD4+ T cells in these patients was associated with HLA-A9, -DR I and DR3. Our data suggest that HLA antigens may contribute to susceptibility to HIV infection and disease progression in Greek haemophiliacs.

    A significant proportion of cattle receive inadequate dietary Se because of its low content in soils and pastures of various regions of the world. Several economically important diseases in dairy cows, such as mastitis, have been associated with Se deficiency. The objective of this study was to evaluate the effect of a single injection of a long-acting form of Se at drying off on the risk and incidence rate of new intramammary infections and on milk somatic cell count in the subsequent lactation in pasture-based dairy cows. Forty-nine Chilean Holstein-Friesian cows were fed a diet containing pasture-based dairy cows did not affect udder health in the subsequent lactation, indicating that Se basal intake was adequate for preventing subclinical mastitis in pasture-based cows in southern Chile.

    Kirkeby, Carsten Thure; Gussmann, Maya Katrin; Græsbøll, Kaare

    Introduction. Mastitis, or intramammary infection (IMI), is one of the most significant diseases in dairy herds worldwide. It is caused by environmental and contagious bacteria. Simulation models have proven useful for evaluating the effect of different control strategies. However, previous...... published models are not cow-specific and therefore not so detailed in the simulation of host-pathogen interactions. If a simulation model is to be used by dairy farmers as a decision-making tool, it needs to be cow-specific because daily management decisions are made on cow level. Furthermore, as IMI......, contagious or mixed), the model should be able to reflect this diversity. Our objective was thus to create a pathogen-, cow- and herd-specific bio-economic simulation model that could simulate multiple pathogens and strains at the same time within a dairy herd. This model should be able to simulate realistic...

    Acquisition of carbapenemase-producing Klebsiella pneumoniae (CP-Kp) strains poses a major threat to critically ill patients. The objectives of this study were to describe the epidemiology of CP-Kp isolates as well as the clinical outcome associated with the corresponding infections and to identify risk factors for mortality of intensive care unit (ICU) patients in a Greek hospital. A prospective, observational study was conducted in a nine-bed general ICU over a 2-year period (April 2010-March 2012). Imipenem-resistant K. pneumoniae isolates recovered from clinical samples of ICU patients were prospectively collected and studied for the presence of carbapenemases. Isolates were submitted to molecular typing using pulsed-field gel electrophoresis (PFGE). In total, 61 CP-Kp isolates (48 KPC-producers and 13 VIM-producers) were recovered from 58 ICU patients. The majority of KPC-producers were classified into a single PFGE type, indicating potent clonal dissemination. Among the 32 infected patients, bacteraemia was diagnosed in 16. Tigecycline+colistin was the most common combination antimicrobial regimen. Infection-attributable mortality was 43.8%. Regarding mortality risk factors, non-survivors were older (P=0.080), all of them presented with septic shock (P=0.010) and they had higher Sepsis-related Organ Failure Assessment (SOFA) scores at infection onset (P=0.004) compared with survivors. Appropriate definitive treatment and combination regimens were not associated with patient survival. In conclusion, CP-Kp infections are associated with limited treatment options and high in-hospital mortality. Effective measures for preventing dissemination of respective isolates in the hospital setting are required. Copyright © 2015 International Society for Chemotherapy of Infection and Cancer.

    Endemic diseases can be counted among the most serious sources of losses for livestock production. In dairy farms in particular, one of the most common diseases is Johne's disease, caused by Mycobacterium avium ssp. paratuberculosis (MAP). Infection with MAP causes direct costs because it affects milk production, but it has also been suspected to increase the risk of clinical mastitis (CM) among infected animals. This might contribute to further costs for farmers. We asked whether MAP infection represents a risk factor for CM and, in particular, whether CM occurrences were more common in MAP-infected animals. Our results, obtained by survival analysis, suggest that MAP-infected cows had an increased probability of experiencing CM during lactation. These results highlight the need to account for the interplay of infectious diseases and other health conditions in economic and epidemiological modeling. In this case, accounting for MAP-infected cows having an increased CM occurrence might have nonnegligible effects on the estimated benefit of MAP control.

    Astronomy as a science began with the Ionian philosophers, with whom Greek philosophy and mathematics also began. While the Egyptians and Babylonians had accomplished much of astronomical worth, it remained for the unrivalled speculative genius of the Greeks, in particular, their mathematical genius, to lay the foundations of the true science of astronomy. In this classic study, a noted scholar discusses in lucid detail the specific advances made by the Greeks, many of whose ideas anticipated the discoveries of modern astronomy.Pythagoras, born at Samos about 572 B.C., was probably the first

    The therapeutic experience of interferon-alpha therapy against hepatitis D virus infection in affected children is rather limited. For this reason, we conducted a retrospective study (duration: 1991-1995) in order to evaluate the efficacy and the safety of interferon-alpha in children suffering from chronic hepatitis D in Northwestern Greece. Seven children who were found to be infected with HDV in a total of 324 children seropositive for hepatitis B virus infection during the 5-year period of the study were treated with interferon-alpha, 3 x 10(6) U/m2 body surface area, intramuscularly or subcutaneously, 3 times weekly for 1 year (after an informed consent obtained from their parents). Patients were assessed monthly by hematological serological and biochemical tests. Clinical progress, levels of serum alanine aminotransferase, hepatitis D ribonucleic acid (HDV-RNA) and hepatitis B deoxyribonucleic acid (HBV-DNA), seroconversion of hepatitis B surface antigen (HBsAg) and Hepatitis Be Antigen (HBeAg) and liver histology were used as response criteria. Posttreatment alanine transferase levels were significantly reduced (P < 0.05) but Immunoglobulin M and total anti-hepatitis D virus (anti-HDV) antibodies remained positive in all, while hepatitis D ribonucleic acid persisted positive in 4 cases. In addition, no seroconversion of HBsAg or HBeAg was noted and the liver histology progress was disappointing. Side effects including mild fever, arthralgias and malaise and reversible neutropenia and thrombocytopenia were common, but not particularly disturbing. Nevertheless, the children remained fully active on treatment, felt well and attended school. Initially 4 children had been below the 10th percentile for weight and height. All thrived during treatment and two crossed above the 10th percentile indicating height velocity and body mass index increase. The administration of regular interferon-alpha doses for treating children with chronic hepatitis D was safe as

    Full Text Available The aim of this study was to evaluate the effects of bovine leukemia virus (BLV infection on productive performance of dairy cattle in Brazil. A total of 158 blood samples from lactating adult cows, purebred Holstein and crossbred Holstein X Zebu, were analyzed by Agar Gel Immunodifusion Test (AGID and leukogram. According to AGID and leukogram results, animals were grouped into three categories: seronegative, seropositive without persistent lymphocytosis, and seropositive with persistent lymphocytosis. Milk production data were compared between groups, according to breed. BLV infected females showed lower milk yield than uninfected ones, both purebred and crossbred ones. There was no difference between milk yield of seropositive cows with or without persistent lymphocytosis. These results indicate an association between BLV infection and reduction of milk production, and this study is the first one to show these effects in crossbred Holstein X Zebu cows.

    For preventive and control strategies of Caprine Arthritis Encephalitis Virus (CAEV) infection in dairy goats, performance of the available diagnostic tests was described as one of the most important and necessary aspects. The study aimed at evaluating the diagnostic test performance, including PCR, ELISA and viral culture, for CAEV infection in dairy goats in Thailand. Blood samples of 29 dairy goats from five low- to medium-prevalence herds and one very low-prevalence herd were collected for PCR and ELISA methods. The performance of these two diagnostic methods was evaluated by comparing with cytopathic effects (CPE) in the co-cultivation of CAEV and primary synovial cells. Results indicated that sensitivity, specificity were, respectively, 69.6%, 100%, for PCR; and 95.7%, 83.3% for ELISA. The PCR assay tended to have lower sensitivity and higher specificity than ELISA. When multiple tests were applied, parallel testing provided sensitivity and specificity of 98.7% and 83.3%, while series testing showed sensitivity and specificity of 66.6% and 100% respectively. These results indicated that combination of ELISA and PCR provided some advantages and possibly offered optimal methods to detect CAEV-infected goats. Kappa value of the agreement between PCR and ELISA test was 0.34, indicating fair agreement. Regarding the possibility of antigenic variation between CAEV strains used in both PCR and ELISA assays, the actual circulating CAEV strain should be reviewed in order to develop and enhance the diagnostic tests using the CAE viral antigens derived from specific local strains of Thailand.

    Full Text Available Cryptosporidium spp. are common intestinal protozoan parasites that causes diarrhoea in neonates and young calves. This longitudinal study was conducted at two large dairy cattle farms in central Ethiopia during February/2014 to June/2015 to determine the age-related distribution of Cryptosporidium species, to identify risk factors of the disease and to assess the public health significance of the parasite. Thirty calves born to these dairy farms were followed-up from birth to three months of age, and 270 faecal samples were collected and examined by the Modified Ziehl-Neelsen, PCR-RFLP and Sequencing. Cryptosporidium was detected from week 1 to 3 months of age with an overall prevalence of 14.8%, Peak of the infection was at two weeks of age when 12 of the 30 calves (40% shedded oocysts. Cryptosporidium parvum and C. andersoni were identified in pre-weaned and post-weaned calves, respectively. Phylogenetic analysis showed clustering of the C. parvum isolates from this study with GenBank sequences for C. parvum bovine genotype IIa and IId subtypes. This study showed the predominance of the zoonotic C. parvum species in pre-weaned calves and demonstrated that this age group of calves pose the greatest risk for human infection. Due attention on the management of pre-weaned calves is recommended to prevent transmission of the infection to humans and lessen contamination of the environment by oocysts.

  1. The relation between input-output transformation and gastrointestinal nematode infections on dairy farms.

    Efficiency analysis is used for assessing links between technical efficiency (TE) of livestock farms and animal diseases. However, previous studies often do not make the link with the allocation of inputs and mainly present average effects that ignore the often huge differences among farms. In this paper, we studied the relationship between exposure to gastrointestinal (GI) nematode infections, the TE and the input allocation on dairy farms. Although the traditional cost allocative efficiency (CAE) indicator adequately measures how a given input allocation differs from the cost-minimising input allocation, they do not represent the unique input allocation of farms. Similar CAE scores may be obtained for farms with different input allocations. Therefore, we propose an adjusted allocative efficiency index (AAEI) to measure the unique input allocation of farms. Combining this AAEI with the TE score allows determining the unique input-output position of each farm. The method is illustrated by estimating efficiency scores using data envelopment analysis (DEA) on a sample of 152 dairy farms in Flanders for which both accountancy and parasitic monitoring data were available. Three groups of farms with a different input-output position can be distinguished based on cluster analysis: (1) technically inefficient farms, with a relatively low use of concentrates per 100 l milk and a high exposure to infection, (2) farms with an intermediate TE, relatively high use of concentrates per 100 l milk and a low exposure to infection, (3) farms with the highest TE, relatively low roughage use per 100 l milk and a relatively high exposure to infection. Correlation analysis indicates for each group how the level of exposure to GI nematodes is associated or not with improved economic performance. The results suggest that improving both the economic performance and exposure to infection seems only of interest for highly TE farms. The findings indicate that current farm recommendations

    Full Text Available Aim: Bovine mastitis and lameness are the most common production diseases affecting dairy farms worldwide resulting in huge economic impact and impaired animal welfare. The objective of this field study was to investigate the association of infectious and non-infectious claw disorders with the occurrence of subclinical intramammary infections (IMIs diagnosed by California mastitis test (CMT in dairy cows under Egyptian conditions. Materials and Methods: A total of 43 dairy cows were included in this field study. Subclinical IMI was diagnosed by CMT on all lactating quarters of cows. A cow was considered to have subclinical IMI if it had at least one subclinically infected quarter (=3. Cows were inspected carefully for claw disorders that recorded based on type and site. Locomotion and body condition scores were also recorded for each cow in addition to the limb affected. The association between the CMT and other explanatory variables was tested by Fisher's exact test. Results: The prevalence of infectious and non-infectious claw disorders was 81.4% (35/43 and 32.6% (14/43, respectively. Digital dermatitis (DD and heel horn erosion were the most prevalent infectious type with 79% (34/43 and 58% (25/43, respectively, while wall fissure was the most identified non-infectious one 11.6% (5/43. The prevalence of claw disorders in hind limbs was 88.4% (38/43 and 11.6% (5/43 in the forelimbs. Infectious claw disorders were significantly associated with the subclinical IMI diagnosed by CMT (p<0.05. Non-infectious claw affections, locomotion score, body condition score, and the affected limb had no association with the occurrence of subclinical IMI. Conclusion: DD is the highest prevalent claw disorder observed in dairy cows in Egypt. The hind limbs are more susceptible to claw disorders than the forelimbs. Infectious type of claw disorders is significantly associated with subclinical IMI diagnosed by CMT in dairy cows under Egyptian conditions indicating

    Full Text Available Fasciolosis is generally a subclinical infection of dairy cows and can cause marked economic losses. This study investigated the prevalence and spatial distribution of fasciolosis in dairy cow herds in Ireland using an in-house antibodydetection enzyme-linked immunosorbent assay applied to bulk tank milk (BTM samples collected during the autumn of 2012. A total of 5,116 BTM samples were collected from 4,602 different herds, with 514 farmers submitting BTM samples in two consecutive months. Analysis of the BTM samples showed that 82% (n = 3,764 of the dairy herds had been exposed to Fasciola hepatica. A total of 108 variables, including averaged climatic data for the period 1981-2010 and contemporary meteorological data for the year 2012, such as soil, subsoil, land cover and habitat maps, were investigated for a possible role as predictor of fasciolosis. Using mainly climatic variables as the major predictors, a model of the predicted risk of fasciolosis was created by Random Forest modelling that had 95% sensitivity and 100% specificity. The most important predictors in descending order of importance were: average of annual total number of rain-days for the period 1981-2010, total rainfall during September, winter and autumn of 2012, average of annual total number of wet-days for the period 1981- 2010 and annual mean temperature of 2012. The findings of this study confirm the high prevalence of fasciolosis in Irish dairy herds and suggest that specific weather and environmental risk factors support a robust and precise distribution model.

  4. Lungworm Infections in German dairy cattle herds--seroprevalence and GIS-supported risk factor analysis.

    Directory of Open Access Journals (Sweden)

    Anne-Marie Schunn

    Full Text Available In November 2008, a total of 19,910 bulk tank milk (BTM samples were obtained from dairy farms from all over Germany, corresponding to about 20% of all German dairy herds, and analysed for antibodies against the bovine lungworm Dictyocaulus viviparus by use of the recombinant MSP-ELISA. A total number of 3,397 (17.1%; n = 19,910 BTM samples tested seropositive. The prevalences in individual German federal states varied between 0.0% and 31.2% positive herds. A geospatial map was drawn to show the distribution of seropositive and seronegative herds per postal code area. ELISA results were further analysed for associations with land-use and climate data. Bivariate statistical analysis was used to identify potential spatial risk factors for dictyocaulosis. Statistically significant positive associations were found between lungworm seropositive herds and the proportion of water bodies and grassed area per postal code area. Variables that showed a statistically significant association with a positive BTM test were included in a logistic regression model, which was further refined by controlled stepwise selection of variables.

    In November 2008, a total of 19,910 bulk tank milk (BTM) samples were obtained from dairy farms from all over Germany, corresponding to about 20% of all German dairy herds, and analysed for antibodies against the bovine lungworm Dictyocaulus viviparus by use of the recombinant MSP-ELISA. A total number of 3,397 (17.1%; n = 19,910) BTM samples tested seropositive. The prevalences in individual German federal states varied between 0.0% and 31.2% positive herds. A geospatial map was drawn to show the distribution of seropositive and seronegative herds per postal code area. ELISA results were further analysed for associations with land-use and climate data. Bivariate statistical analysis was used to identify potential spatial risk factors for dictyocaulosis. Statistically significant positive associations were found between lungworm seropositive herds and the proportion of water bodies and grassed area per postal code area. Variables that showed a statistically significant association with a positive BTM test were included in a logistic regression model, which was further refined by controlled stepwise selection of variables. The low Pseudo R2 values (0.08 for the full model and 0.06 for the final model) and further evaluation of the model by ROC analysis indicate that additional, unrecorded factors (e.g. management factors) or random effects may substantially contribute to lungworm infections in dairy cows. Veterinarians should include lungworms in the differential diagnosis of respiratory disease in dairy cattle, particularly those at pasture.

    Full Text Available Abstract Background Infection with bovine herpesvirus-1 (BHV-1 causes a wide range of disease manifestations, including respiratory disease and abortion, with world-wide distribution. The primary objective of the present study was to describe aspects of BHV-1 infection and control on Irish farms, including herd-level seroprevalence (based on pooled sera and vaccine usage. Methods The characteristics of a diagnostic indirect BHV-1 antibody ELISA test when used on serum pools were evaluated using laboratory replicates for use in the seroprevalence study. The output from this indirect ELISA was expressed as a percentage positivity (PP value. A proposed cut off (PCO PP was applied in a cross-sectional study of a stratified random sample of 1,175 Irish dairy and beef cattle herds in 2009, using serum pools, to estimate herd seroprevalence. The study was observational, based primarily on the analysis of existing samples, and only aggregated results were reported. For these reasons, ethical approval was not required. Bulk milk samples from a subset of 111 dairy herds were analysed using the same ELISA. Information regarding vaccine usage was determined in a telephone survey. Results A PCO PP of 7.88% was determined to give 97.1% sensitivity and 100% specificity relative to the use of the ELISA on individual sera giving maximization of the prevalence independent Youden's index, on receiver operating characteristics analysis of replicate results. The herd-level BHV-1 seroprevalence was 74.9% (95% CI - 69.9%-79.8%, with no significant difference between dairy and beef herds. 95.5% agreement in herd classification was found between bulk milk and serum pools. Only 1.8 percent of farmers used BHV-1 marker vaccine, 80% of which was live while 75% of vaccinated herds were dairy. A significant association was found between herd size (quartiles and seroprevalence (quartiles. Conclusions The results from this study indicate BHV-1 infection is endemic, although

    Meticillin-resistant staphylococcus aureus (MRSA) is an important cause of antimicrobial-resistant infections worldwide. Its prevalence remains high in the Greek hospital setting. Complicated skin and soft tissue infections (cSSTIs) due to MRSA are associated with prolonged hospitalization, additional healthcare costs and significant morbidity. The purpose of this study was to conduct a cost analysis and a budget impact analysis relative to different management scenarios for MRSA-cSSTIs from a hospital perspective. Equal efficacy was assumed for the pharmacotherapies under evaluation and resource use was elicited via an expert panel of seven local infectious disease specialists. The model was based on a previously published economic model that was adapted for the Greek hospital setting and included a decision tree for the management of hospitalized patients with MRSA-cSSTIs, which simulated costs and outcomes for the duration of hospitalization according to the therapeutic scenario. Inpatient costs consisted of hospitalization, diagnostic/laboratory testing, physician visits and antibiotic treatment. Current economic impact of MRSA-cSSTIs for the inpatient setting in Greek hospitals was estimated at €29,196,218. Total per patient cost according to first-line agent was €2,457, €2,762, €2,850, €3,494 and €3,094 and mean length of stay was 9.2, 12.5, 10.3, 13.0 and 14.0 days for linezolid, vancomycin, daptomycin, tigecycline, and teicoplanin, respectively. An estimated 10,287 MRSA-cSSTI patients are treated annually in Greek hospitals. Thus, increasing the use of linezolid by 11% over a 3-year period (current use 19%; 3 year projection 30%), for the management of MRSA-cSSTIs, could result in 3-year savings of €896,065. Management of MRSA-cSSTI requires intensive resource use; overall healthcare costs differ according to the chosen first-line treatment. In light of considerable budget constraints, development of hospital strategies which facilitate

    Full Text Available Abstract Background Mastitis is the most important and costly disease in dairy goat production. Subclinical mastitis is common in goats and is mainly caused by contagious bacteria. Several methods to diagnose subclinical mastitis are available. In this study indirect measurement of somatic cell count (SCC by California Mastitis Test (CMT and direct measurement of SCC using a portable deLaval cell counter (DCC are evaluated. Swedish goat farmers would primarily benefit from diagnostic methods that can be used at the farm. The purpose of the study was to evaluate SCC measured by CMT and DCC as possible markers for intramammary infection (IMI in goats without clinical symptoms of mastitis. Moreover to see how well indirect measurement of SCC (CMT corresponded to direct measurement of SCC (DCC. Method Udder half milk samples were collected once from dairy goats (n = 111, in five different farms in Northern and Central Sweden. Only clinically healthy animals were included in the study. All goats were in mid to late lactation at sampling. Milk samples were analyzed for SCC by CMT and DCC at the farm, and for bacterial growth at the laboratory. Results Intramammary infection, defined as growth of udder pathogens, was found in 39 (18% of the milk samples. No growth was found in 180 (81% samples while 3 (1% samples were contaminated. The most frequently isolated bacterial species was coagulase negative staphylococci (CNS (72% of all isolates, followed by Staphylococcus aureus (23% of all isolates. Somatic cell count measured by DCC was strongly (p = 0.000 associated with bacterial growth. There was also a very strong association between CMT and bacterial growth. CMT 1 was associated with freedom of IMI while CMT ≥2 was associated with IMI. Indirect measurement of SCC by CMT was well correlated with SCC measured by DCC. Conclusions According to the results, SCC measured with CMT or DCC can predict udder infection in goats, and CMT can be used as a

    Paratuberculosis is an economically important disease of dairy cattle caused by Mycobacterium avium subsp. paratuberculosis (Map). The role of nonruminant, nondomestic animals in the epidemiology of paratuberculosis in cattle is unclear. To examine nonruminant, nondomestic animals for the presence of Map, 25 feral cats, nine mice (species unknown), eight rabbits (Sylvilagus floridanus), six raccoons (Procyon lotor), and three opossums (Didelphis virginiana) were collected from a mid-western dairy with known Map-infected cattle. Mycobacterium avium subsp. paratuberculosis was isolated from the mesenteric lymph node from seven of 25 (28%) feral cats. Ileum was culture-positive for three of these seven cats, and an isolation of Map was also made from the ileum of one of nine (11%) mice. Tissue samples from other species were negative as determined by Map culture; microscopic lesions consistent with paratuberculosis were not seen in any animal. Restriction fragment polymorphism analysis of isolates from cats and dairy cattle suggest interspecies transmission. The means by which interspecies transmission occurred may be through ingestion of Map-contaminated feces or waste milk or through ingestion of Map-infected prey. Shedding of Map from infected cats was not evaluated. The epidemiologic role of Map-infected feral cats on dairy farms requires further investigation.

    Cryptosporidiosis, microsporidiosis, and giardiasis contribute significantly to the high burden of zoonotic diarrhea worldwide. Goats constitute an important species in animal agriculture by providing cashmere wool, meat, and dairy products for human consumption. However, zoonotic pathogens with the potential to cause morbidity and to degrade production have been reported frequently in goats recently. The present study examined 629 fecal specimens from goats, including 315 cashmere goats, 170 dairy goats and 144 meat goats, in multiple cities of Shaanxi and Henan provinces, northwestern and central China, to investigate the infection rate and species/assemblages/genotypes of Giardia duodenalis, Cryptosporidium spp. and Enterocytozoon bieneusi. Of these samples, 274 (43.6%) were positive for three zoonotic pathogens, including 80 (12.7%), 104 (16.5%) and 179 (28.5%) for G. duodenalis, Cryptosporidium spp. and E. bieneusi, respectively. Infections with G. duodenalis, Cryptosporidium spp. and E. bieneusi existed in meat, dairy and cashmere goats, with the highest infection rate of each pathogen being observed in meat goats. DNA sequencing of the SSU rRNA gene from 104 Cryptosporidium-positive specimens revealed existence of Cryptosporidium xiaoi, and the zoonotic parasites Cryptosporidium parvum and Cryptosporidium ubiquitum. Genotyping of G. duodenalis based on the triosephosphate isomerase (TPI) gene identified parasites from zoonotic assemblage A in four cashmere goats and the animal-adapted assemblage E in a group of 76 goats that included cashmere, dairy and meat animals. Polymorphisms in the ribosomal internal transcribed spacer characterized E. bieneusi genotype CHG1 and a novel genotype named as SX1 in both dairy and cashmere goats, genotypes CHS7 and COSI in meat goats, the genotype CHG2 in dairy goats, and the human-pathogenic genotype BEB6 in dairy and meat goats. This is the first detailed study to compare infection rate of the zoonotic protozoan pathogens

    The objective of this study was to investigate if and how cow factors and intramammary infection (IMI) are associated with 4 different udder-health indicators in dairy cows as a first step in investigating whether the diagnostic performance of these indicators can be improved. The investigated indicators were somatic cell count (SCC), lactate dehydrogenase (LDH), N-acetyl-β-d-glucosaminidase (NAGase), and alkaline phosphatase (AP) measured in milk. In this cross-sectional study, approximately 1,000 cows from 25 dairy herds were sampled for bacteriology (quarter milk samples) during 3 consecutive days: the day before test milking, at the day of test milking, and at the day after test milking. The whole-udder test milking sample was analyzed for milk composition, SCC, LDH, NAGase, and AP. Cow data (parity, breed, milk yield, percentage of milk fat and protein, milk urea concentration, and days in milk from the sampled test milking) were collected from the Swedish milk-recording scheme. Of the sampled cows 485 were considered IMI negative and were used in multivariable mixed-effect linear regression models to investigate associations between cow factors and the udder-health indicators. A second modeling including all cows, both IMI negative and IMI positive (256 cows), was also performed. The results showed that all udder-health indicators were affected by cow factors but that different cow factors were associated with different indicators. Intramammary-infection status was significantly associated with all udder-health indicators except AP. Parity and milk urea concentration were the only cow factors associated with all indicators in all models. The significant cow factors explained 23% of the variation in SCC and >30% of the variation in LDH, NAGase, and AP in IMI-negative cows, showing that LDH, NAGase, and AP are more affected than SCC by cow factors. The IMI status explained 23% of the variation in SCC in the model with all cows but only 7% of the variation in

    Using specific ELISAs, antibody levels of four different isotypes to bovine respiratory syncytial virus (BRSV) were determined in calves, following experimental BRSV infection. Most calves experienced an increase in the specific IgM and IgG1 titres about 6-10 days after infection with BRSV. The Ig......M titre was transient showing positive titres for only 5-10 days, while specific IgG1 was present for a longer time. IgA was detected concomitantly with IgM but at a lower level.

    Full Text Available 66 Pampinta breed ewes were studied during milking to evaluate the infection and the effect of gastrointestinal nematode on milk production sheep system. Naturally infected ewes on pasture were randomly allocated to two groups: TG, suppressively treated group every four weeks with levamisole and UG, untreated group. Faecal nematode egg counts and larval differentiation were conducted monthly. Successive groups of worm free tracer lambs were grazed with ewes and then slaughtered for worm counts. Test-day milk yield of individual ewes was recorded and ewe machine-milking period length (MPL were estimated. Faecal egg counts and tracer nematode numbers increased towards midsummer and declined sharply toward the end of the study. TG (188.0 ± 60 liters produced more (p < 0.066 milk liters than UG (171.9 ± 52.2 and TG had significantly more extended (p < 0.041 MPL than those of UG. The present study showed that dairy sheep were negatively affected by worms, even when exposed to short periods of high acute nematode (mainly Haemonchus contortus infection.

    Full Text Available A longitudinal study was performed in a Swedish dairy herd where Neospora caninum had been isolated from a stillborn calf. Starting in autumn 1994, blood samples from all female animals in the herd were collected once yearly until 1999. The sera were analysed for presence of IgG1 antibodies to N. caninum by the iscom ELISA, and by an avidity ELISA to establish the timing of infection. In addition, data on reproductive performance were compiled. During the study the percentage of seropositive female animals increased from 63% to 87%. In 1994 a large number of young animals tested seropositive although their dams were seronegative, indicating that a transmission of the parasite other than the vertical had recently occurred. Low avidity values supported this assumption. The annual abortion rate increased from a mean of 2% before the initiation of the study to 9% in 1994–1998. During the same time, as judged by the avidity data, a large proportion of the animals shifted from being recently to being chronically infected. The source of the external infection in the herd could not be identified.

    Full Text Available Animals' exchanges are considered the most effective route of between-farm infectious disease transmission. However, despite being often overlooked, the infection spread due to contaminated equipment, vehicles, or personnel proved to be important for several livestock epidemics. This study investigated the role of indirect contacts in a potential infection spread in the dairy farm network of the Province of Parma (Northern Italy. We built between-farm contact networks using data on cattle exchange (direct contacts, and on-farm visits by veterinarians (indirect contacts. We compared the features of the contact structures by using measures on static and temporal networks. We assessed the disease spreading potential of the direct and indirect network structures in the farm system by using data on the infection state of farms by paratuberculosis. Direct and indirect networks showed non-trivial differences with respect to connectivity, contact distribution, and super-spreaders identification. Furthermore, our analyses on paratuberculosis data suggested that the contributions of direct and indirect contacts on diseases spread are apparent at different spatial scales. Our results highlighted the potential role of indirect contacts in between-farm disease spread and underlined the need for a deeper understanding of these contacts to develop better strategies for prevention of livestock epidemics.

    Full Text Available Bovine besnoitiosis, caused by Besnoitia besnoiti, is a (reemerging disease in Europe (Cortes et al., 2014, including Italy (Gazzonis et al., 2014; 2017. However, its economic impact is scarcely considered and generally underestimated and there are still little studied aspects concerning both the parasite and the disease. Following a natural outbreak of besnoitiosis in a dairy herd, a study was planned to characterize B. besnoiti infection in cattle through a multidisciplinary approach. Suspicious abortions and clinical cases of besnoitiosis were reported in a dairy farm (September 2017, Northern Italy housing 216 Holstein cattle. Blood samples were collected; haematological and serological analyses (ELISA and confirmatory WB were performed (Fernandez-Garcia et al., 2009. Histology and molecular (endpoint ITS-1 PCR (Cortes et al., 2007 and sequencing analyses of tissues from a slaughtered cow with chronic besnoitiosis were carried out.  Out of 59 ELISA-positive animals, 50 (23% were confirmed by WB. B. besnoiti prevalence was higher in cows (41% than in calves (12%; any heifer did not result positive. Considering haematological parameters, a significant shift in the differential leucocyte formula from lymphocyte to granulocyte was recorded in infected cows (Mean±S.D.:L=46.1±18.4,G=53.9±18.4 if compared to negative animals (Student’s T-test,p=0.012. This finding could be helpful in diagnosis, treatment and control of besnoitiosis. Histology revealed a high load of B. besnoiti tissue cysts in skin, vulva, muzzle, sclera, eyelid, respiratory tract, emphasizing the possibility of parasite transmission through direct contact among animals. B. besnoiti was confirmed by PCR in other organs (heart, liver, aorta wall, tonsil and especially in ovary, uterus and vulva, suggesting that the infection could affect cows’ fertility. Parasite DNA was also found in masseters posing an important question for food security, even if B. besnoiti is not

    Several decades after the inception of the five-point plan for the control of contagious mastitis pathogens, Streptococcus agalactiae (S. agalactiae) persists as a fundamental threat to the dairy industry in many countries. A better understanding of the relative importance of within- and between-herd sources of new herd infections coupled with the spatiotemporal distribution of the infection, may aid in effective targeting of control efforts. Thus, the objectives of this study were: (1) to describe the spatiotemporal patterns of infection with S. agalactiae in the population of Danish dairy herds from 2000 to 2009 and (2) to estimate the annual herd-level baseline and movement-related incidence risks of S. agalactiae infection over the 10-year period. The analysis involved registry data on bacteriological culture of all bulk tank milk samples collected as part of the mandatory Danish S. agalactiae surveillance scheme as well as live cattle movements into dairy herds during the specified 10-year period. The results indicated that the predicted risk of a herd becoming infected with S. agalactiae varied spatiotemporally; the risk being more homogeneous and higher in the period after 2005. Additionally, the annual baseline risks yielded significant yet distinctive patterns before and after 2005 - the risk of infection being higher in the latter phase. On the contrary, the annual movement-related risks revealed a non-significant pattern over the 10-year period. There was neither evidence for spatial clustering of cases relative to the population of herds at risk nor spatial dependency between herds. Nevertheless, the results signal a need to beef up within-herd biosecurity in order to reduce the risk of new herd infections. Copyright © 2013 Elsevier B.V. All rights reserved.

  2. Prevalence of latent and active tuberculosis among dairy farm workers exposed to cattle infected by Mycobacterium bovis.

    Directory of Open Access Journals (Sweden)

    Pedro Torres-Gonzalez

    Full Text Available BACKGROUND: Human tuberculosis caused by M. bovis is a zoonosis presently considered sporadic in developed countries, but remains a poorly studied problem in low and middle resource countries. The disease in humans is mainly attributed to unpasteurized dairy products consumption. However, transmission due to exposure of humans to infected animals has been also recognized. The prevalence of tuberculosis infection and associated risk factors have been insufficiently characterized among dairy farm workers (DFW exposed in settings with poor control of bovine tuberculosis. METHODOLOGY/PRINCIPAL FINDINGS: Tuberculin skin test (TST and Interferon-gamma release assay (IGRA were administered to 311 dairy farm and abattoir workers and their household contacts linked to a dairy production and livestock facility in Mexico. Sputa of individuals with respiratory symptoms and samples from routine cattle necropsies were cultured for M. bovis and resulting spoligotypes were compared. The overall prevalence of latent tuberculosis infection (LTBI was 76.2% (95% CI, 71.4-80.9% by TST and 58.5% (95% CI, 53.0-64.0% by IGRA. Occupational exposure was associated to TST (OR 2.72; 95% CI, 1.31-5.64 and IGRA (OR 2.38; 95% CI, 1.31-4.30 adjusting for relevant variables. Two subjects were diagnosed with pulmonary tuberculosis, both caused by M. bovis. In one case, the spoligotype was identical to a strain isolated from bovines. CONCLUSIONS: We documented a high prevalence of latent and pulmonary TB among workers exposed to cattle infected with M. bovis, and increased risk among those occupationally exposed in non-ventilated spaces. Interspecies transmission is frequent and represents an occupational hazard in this setting.

    Full Text Available Abstract Background The primary aims of this study were to determine the incidence of Giardia infections in dairy herds on farms in the New York City Watershed region and to evaluate risk factors associated with infections. Because co-infections of Giardia and Cryptosporidium spp. are common in this population, we also evaluated the effect of herd infection status on Giardia infections. Methods Farms were grouped into three cohorts based on their prior infection status with Giardia and/or Cryptosporidium spp. The sampling plan included collecting fecal samples from all calves below 30 days of age and proportional sampling of calves, young stock, and adults. A total of 10,672 fecal samples were collected and analyzed for the presence of Giardia cysts using zinc sulfate flotation. Herds enrolled in the study were sampled seasonally for a study period of two years. The probability of shedding cysts past a certain age and the factors that influenced the likelihood of shedding were evaluated using survival analysis. Linear regression was used to evaluate factors that were associated with the intensity of shedding. Results The majority of Giardia infections occurred in calves within their first 180 days of age, with the most number of calves shedding Giardia cysts between 11 and 20 days of age. The incidence of shedding of Giardia cysts ranged from 0.0004 per animal day for cattle in the low risk cohort to 0.0011 per animal day for cattle in the high risk cohort. The likelihood of shedding was influenced by the prior infection status of the herd and the season of collection. Infected animals shed on average 9,658 cysts/gram and the intensity of shedding Giardia cysts varied significantly with the age (p Conclusion Giardia infections are common in dairy herds in the New York City watershed, particularly in calves less than 6 months of age. Seasonality may be an important factor in the perpetuation of infections based on changes in management practices

    The impact of gastrointestinal (GI) nematode infections in dairy farming has traditionally been assessed using partial productivity indicators. But such approaches ignore the impact of infection on the performance of the whole farm. In this study, efficiency analysis was used to study the association of the GI nematode Ostertagia ostertagi on the technical efficiency of dairy farms. Five years of accountancy data were linked to GI nematode infection data gained from a longitudinal parasitic monitoring campaign. The level of exposure to GI nematodes was based on bulk-tank milk ELISA tests, which measure the antibodies to O. ostertagi and was expressed as an optical density ratio (ODR). Two unbalanced data panels were created for the period 2006 to 2010. The first data panel contained 198 observations from the Belgian Farm Accountancy Data Network (Brussels, Belgium) and the second contained 622 observations from the Boerenbond Flemish farmers' union (Leuven, Belgium) accountancy system (Tiber Farm Accounting System). We used the stochastic frontier analysis approach and defined inefficiency effect models specified with the Cobb-Douglas and transcendental logarithmic (Translog) functional form. To assess the efficiency scores, milk production was considered as the main output variable. Six input variables were used: concentrates, roughage, pasture, number of dairy cows, animal health costs, and labor. The ODR of each individual farm served as an explanatory variable of inefficiency. An increase in the level of exposure to GI nematodes was associated with a decrease in technical efficiency. Exposure to GI nematodes constrains the productivity of pasture, health, and labor but does not cause inefficiency in the use of concentrates, roughage, and dairy cows. Lowering the level of infection in the interquartile range (0.271 ODR) was associated with an average milk production increase of 27, 19, and 9L/cow per year for Farm Accountancy Data Network farms and 63, 49, and

    Paratuberculosis is a challenging disease to control at farm level, in part due to the poor sensitivity of diagnostic tests and a prolonged incubation period. Simulation studies have highlighted on-farm management to be the most important factor in preventing on-farm spread. A risk assessment (RA) and management plan (MP) approach (collectively, RAMP) has been adopted around the world as the most appropriate method of controlling disease in infected farms. However, there are problems with RAMP that remain to be resolved. The RA relies heavily on farmer recollection and estimation resulting in subjectivity and substantial inter-observer variability. MPs consist of a series of qualitative, farm specific recommendations showing how management can be improved. However, MP assessment is generally conducted informally, and progress is monitored through 'end-point' diagnostic testing of adult animals and repeated risk assessments. Hazard analysis and critical control point (HACCP) has been developed as a proactive alternative to end-point testing. We hypothesise that farm-based HACCP systems may be a useful alternative to RAMP on farms where more intensive monitoring and evaluation of controls for paratuberculosis is required. Therefore, the objective of this methodological study was to develop a HACCP-based system for paratuberculosis control. Critical control points (CCPs) relating to peri-parturient area management, calving, new-born calf management and colostrum management were identified as areas where additional control could be exerted above existing methods. Novel monitoring systems were developed for each CCP, along with targets and corrective actions. This system is intended for use in high prevalence herds, or farms where more robust monitoring of key control points may be beneficial. It is currently being trialled on infected commercial dairy herds in Ireland. Copyright © 2015 Elsevier B.V. All rights reserved.

    Neospora caninum causes reproductive problems in cattle such as abortion, premature birth, retention of fetal membranes, and metritis. Therefore, this study aimed to verify possible risk factors for N. caninum infection in dairy cattle and their cause-effect relation to neosporosis. Serum samples of 1518 dairy cows from the West of Santa Catarina State, Southern Brazil were analyzed by indirect immunofluorescence assay (IFA) for N. caninum, where 466 were found to be positives (30.69%-CI 95% ; 28.3-33.0). In addition, an epidemiological survey was conducted in order to verify possible risk factors for neosporosis and their relation to the disease. The presence of dogs in the farm was strongly associated with IFA positive results for N. caninum, and lack of history for neosporosis in the farm increased the chances of positivity in 66%. It was found a significant cause-effect relation between the occurrence of reproductive problems and the presence of antibodies against N. caninum (p = 0.05). It is possible to conclude that N. caninum is widely distributed in dairy farms of the Western part of Santa Catarina state, Brazil, and that the occurrence of reproductive problems is directly related to the disease with the presence of dogs as a risk factor for N. caninum infection.

    Group G streptococci in animals usually belong to the species Streptococcus canis and are most commonly found in dogs and cats. Occasionally, Strep. canis is detected in milk from dairy cows. An outbreak of Strep. canis mastitis in a dairy herd is described. Based on results from bacterial culture and ribotyping, a cat with chronic sinusitis was the most likely source of the outbreak. Subsequent cow-to-cow transmission of Strep. canis was facilitated by poor udder health management, including use of a common udder cloth and failure to use postmilking teat disinfection. Infected cows had macroscopically normal udders and milk, but significantly higher somatic cell counts than Strep. canis-negative herd mates. The outbreak was controlled through antibiotic treatment of lactating cows, early dry-off with dry cow therapy, culling of infected animals, and implementation of standard mastitis prevention measures. Cure was significantly more likely in dry-treated cows (87.5%) and cows treated during lactation (67%) than in untreated cows (9%). Whereas mastitis due to group G streptococci or Strep. canis in dairy cows is usually limited to sporadic cases of environmental (canine or feline) origin, this case study shows that crossing of the host species barrier by Strep. canis may result in an outbreak of mastitis if management conditions are conducive to contagious transmission. In such a situation, measures that are successful in control of Strep. agalactiae can also be used to control Strep. canis mastitis.

    Intramammary infections (IMI) in dairy cattle lead to economic losses for farmers, both through reduced milk production and disease control measures. We present the first strain-, cow- and herd-specific bio-economic simulation model of intramammary infections in a dairy cattle herd. The model can be used to investigate the cost-effectiveness of different prevention and control strategies against IMI. The objective of this study was to describe a transmission framework, which simulates spread of IMI causing pathogens through different transmission modes. These include the traditional contagious and environmental spread and a new opportunistic transmission mode. In addition, the within-herd transmission dynamics of IMI causing pathogens were studied. Sensitivity analysis was conducted to investigate the influence of input parameters on model predictions. The results show that the model is able to represent various within-herd levels of IMI prevalence, depending on the simulated pathogens and their parameter settings. The parameters can be adjusted to include different combinations of IMI causing pathogens at different prevalence levels, representing herd-specific situations. The model is most sensitive to varying the transmission rate parameters and the strain-specific recovery rates from IMI. It can be used for investigating both short term operational and long term strategic decisions for the prevention and control of IMI in dairy cattle herds. Copyright © 2018 Elsevier Ltd.

    A total of 854 paired milk and blood samples were collected from ewes of a Greek flock and used to estimate the sensitivity and specificity of a commercial ELISA for detection of Mycobacterium avium subsp. paratuberculosis (MAP) specific antibodies in each stage of lactation. We implemented Bayesian mixture models to derive the distributions of the test response for the healthy and the infected ewes. In the colostrum period, early, mid and late lactation stage the median values of the area under the curves (AUC) were 0.61 (95% credible interval: 0.50; 0.84), 0.61 (0.51;0.84), 0.65 (0.51;0.91), 0.65(0.51;0.89) for the serum ELISA and and 0.60 (0.50; 0.84), 0.61 (0.50; 0.84), 0.67(0.51; 0.91), 0.66(0.50; 0.90) for the milk ELISA, respectively. Both serum and milk ELISA had low to average overall discriminatory ability as measured by the area under the curves and comparable sensitivities and specificities at the recommended cutoffs.

    Full Text Available A total of 355 cows were sampled (serum, n=315; faeces, n=355; milk, n=209 from dairy farms located in the Punjab state of India. Faeces and serum/milk samples were screened by acid fast staining and “indigenous ELISA,” respectively. IS900 PCR was used to screen faeces and milk samples. Bio-load of MAP in dairy cows was 36.9, 15.6, 16.3, and 14.4%, using microscopy, serum ELISA, milk ELISA and milk PCR, respectively. Estimated kappa values between different test combinations: serum and milk ELISA, faecal microscopy and faecal PCR, milk ELISA and milk PCR, faecal PCR and serum ELISA were 0.325, 0.241, 0.682, and 0.677, respectively. Estimation of the relative sensitivity and specificity of different tests in the present study indicated that “serum ELISA” and “milk ELISA” were good screening tests, add “milk PCR” was “confirmatory test” for MAP infection. Combination of milk ELISA with milk PCR may be adopted as a model strategy for screening and diagnosis of JD in lactating/dairy cattle herds in Indian conditions.

    Infections with gastrointestinal nematodes (GIN) can lead to production losses and impacts on product quality in affected cows, which has mainly been demonstrated during deworming experiments or via herd-level measurements. Here, a field study was carried out to explore the association between GIN infection status and milk production as well as fertility parameters in individual dairy cows. Different selection lines of Black and White cows were included in the study, which were distributed among 17 small and medium-sized organic and conventional German grassland farms. Faecal samples of 1166 dairy cows were examined twice, in July and September 2015. Nematode eggs were found in the faeces of 473 (40.6%) cows. As expected, strongylid eggs (Trichostrongylidae or Oesophagostomum and Bunostomum spp., respectively) were the predominant morphotype, followed by Strongyloides papillosus and Capillaria spp. eggs. In July, cows kept under organic conditions had a significantly lower GIN prevalence in comparison to cows kept on conventional farms. Faecal egg counts were generally low, with the highest value in September and an arithmetic mean of 11.3 eggs per gram faeces (EPG) for all observations. The relationships between GIN infection status and milk yield (kg milk/cow/day), milk protein content (%) and milk fat content (%) for each first test-day record after parasitological assessment were estimated by using linear mixed models. Milk protein content was estimated 0.05% lower in GIN positive compared to GIN negative cows, whereas no significant effect on milk yield or milk fat content was observed. The impact of GIN infection status on success in first insemination (SFI) was estimated by using a threshold model. No significant association was demonstrated between GIN infection status and SFI. Unexpectedly, the fertility parameter days from calving-to-first-service (CTFS) showed a significantly shorter average interval in GIN positive cows. However, these data on

    This study investigated the incidence of mycoplasma infection in the uterus of postpartum Holstein dairy cows and its relationship to the occurrence of endometritis. The genital tracts of 209 cows from three dairy farms in the Iwate Prefecture, Japan, were examined at Weeks 5 and 7 postpartum. The condition of the cervicovaginal mucus was assessed using a Metricheck device and assigned a score from 0 (clear mucus) to 4 (purulent material with fetid odor). Intrauterine samples (N = 418) were collected at Weeks 5 and 7 postpartum using a cytobrush. After its withdrawal, swab samples were placed in mycoplasma culture broth at 37 °C for 72 hours. A novel and rapid polymerase chain reaction was used to detect seven mycoplasma species (Mycoplasma bovis, M. arginini, M. bovigenitalium, M. californicum, M. bovirhinis, M. alkalescens, and M. canadense). The cytobrush was also rolled gently along the length of a glass slide for subsequent polymorphonuclear neutrophil count. The diagnostic criteria for cytological endometritis were 6% or more and 4% or more polymorphonuclear neutrophils at Weeks 5 and 7, respectively. From a subset of cows, additional swabs were rolled against the cytobrush and then placed in transport medium. These samples were then plated on specific agar plates and cultured under aerobic and anaerobic conditions to identify other bacteria present. The incidence of dystocia at the last calving was compared in mycoplasma positive and negative cows. Of the seven mycoplasma species, only M. bovigenitalium was detected; it was detected in 31 of the 418 uterine swabs (7.4%). Twenty-four cows were positive for M. bovigenitalium (eight cows at Week 5, nine cows at Week 7, and seven cows at both Weeks 5 and 7). The incidence of dystocia was higher (P dystocia at last calving and subsequent uterine infection with other bacteria. In addition, the incidence of cytologic endometritis was higher (P dystocia and with cytologic endometritis in postpartum dairy cows

    As part of a broader control strategy within herds known to be infected with Mycobacterium avium ssp. paratuberculosis (MAP), individual animal testing is generally conducted to identify infected animals for action, usually culling. Opportunities are now available to quantitatively compare different testing strategies (combinations of tests) in known infected herds. This study evaluates the effectiveness, cost, and cost-effectiveness of different testing strategies to identify infected animals at a single round of testing within dairy herds known to be MAP infected. A model was developed, taking account of both within-herd infection dynamics and test performance, to simulate the use of different tests at a single round of testing in a known infected herd. Model inputs included the number of animals at different stages of infection, the sensitivity and specificity of each test, and the costs of testing and culling. Testing strategies included either milk or serum ELISA alone or with fecal culture in series. Model outputs included effectiveness (detection fraction, the proportion of truly infected animals in the herd that are successfully detected by the testing strategy), cost, and cost-effectiveness (testing cost per true positive detected, total cost per true positive detected). Several assumptions were made: MAP was introduced with a single animal and no management interventions were implemented to limit within-herd transmission of MAP before this test. In medium herds, between 7 and 26% of infected animals are detected at a single round of testing, the former using the milk ELISA and fecal culture in series 5 yr after MAP introduction and the latter using fecal culture alone 15 yr after MAP introduction. The combined costs of testing and culling at a single round of testing increases with time since introduction of MAP infection, with culling costs being much greater than testing costs. The cost-effectiveness of testing varied by testing strategy. It was also

    infections were less common during the pasture season than during the late housing season. The relative occurrence of the 3 pathogens, infection types of each pathogen, and genotype diversity of each pathogen throughout the year or in different seasons and parities varied among the herds, indicating that underlying factors predisposing for udder infections at calving differ between herds. Genotyping of bacterial isolates gave important insight into how such infection patterns differed within and between herds.

    Non-aureus staphylococci (NAS), the microorganisms most frequently isolated from bovine milk worldwide, are a heterogeneous group of numerous species. To establish their importance as a group, the distribution of individual species needs to be determined. In the present study, NAS intramammary infection (IMI) was defined as a milk sample containing ≥1,000 cfu/mL in pure or mixed culture that was obtained from a cohort of cows assembled by the Canadian Bovine Mastitis Research Network. Overall, 6,213 (6.3%) of 98,233 quarter-milk samples from 5,149 cows and 20,305 udder quarters were associated with an NAS IMI. Of the 6,213 phenotypically identified NAS isolates, 5,509 (89%) were stored by the Canadian Bovine Mastitis Research Network Mastitis Pathogen Collection and characterized using partial sequencing of the rpoB housekeeping gene, confirming 5,434 isolates as NAS. Prevalence of each NAS species IMI was estimated using Bayesian models, with presence of a specific NAS species as the outcome. Overall quarter-level NAS IMI prevalence was 26%. The most prevalent species causing IMI were Staphylococcus chromogenes (13%), Staphylococcus simulans (4%), Staphylococcus haemolyticus (3%), Staphylococcus xylosus (2%), and Staphylococcus epidermidis (1%). The prevalence of NAS IMI as a group was highest in first-parity heifers and was evenly distributed throughout cows in parities ≥2. The IMI prevalence of some species such as S. chromogenes, S. simulans, and S. epidermidis differed among parities. Overall prevalence of NAS IMI was 35% at calving, decreased over the next 10 d, and then gradually increased until the end of lactation. The prevalence of S. chromogenes, Staphylococcus gallinarum, Staphylococcus cohnii, and Staphylococcus capitis was highest at calving, whereas the prevalence of S. chromogenes, S. haemolyticus, S. xylosus, and S. cohnii increased during lactation. Although the overall prevalence of NAS IMI was similar across barn types, the prevalence of S

    Full Text Available The aim of this investigation was to conduct an epidemiological study and identify risk factors associated with the occurrence of paratuberculosis (Johne’s disease in dairy goats within the semiarid region of Paraíba State. The study was done during the period of March 2009 to July 2011, during which 727 female goats from 86 flocks from the city of Monteiro, Paraíba were investigated. For the serological diagnosis of Mycobacterium avium subsp. paratuberculosis (Map infection indirect ELISA tests (screening and confirmatory were performed. Of the 727 animals used six (0.82% were seropositive at the confirmatory test after screening, and of the 86 flocks six (6.97% presented at least one seropositive animal. In positive flocks the frequency of reactive animals ranged from 5.26% to 16.60%. Risk factors identified were production system (weaning and reproduction (odds ratio = 36.0; 95% CI = 2.6 –486.1; p < 0,001 and absence of technical infrastructure (odds ratio = 54.0; 95% CI = 4.5 –642.9; p < 0,001. It was concluded that Mycobacterium avium subsp. paratuberculosis is present in dairy goat flocks in the region; however, its influence on decrease productivity as well as the risk of transmission to humans through animal products must totally evaluated. Based on the analysis of risk factors, improvements are recommended for the technical infrastructure and the management of breeding goats.

    Neosporosis is considered a major cause of abortion among cattle worldwide. The aim of this study was to investigate the prevalence of anti-Neospora caninum antibodies in dairy cattle and correlate them with possible risk factors on 63 small farms (family farms) in the municipality of Ji-Paraná, the main milk-producing region of the state of Rondônia, northern Brazil. For this purpose, 621 serum samples were collected from cows and were evaluated by means of the indirect fluorescence antibody test (IFAT). The overall herd prevalence of N. caninum antibodies among the farms (38/63; 60.31%) showed that N. caninum are widespread among the dairy herds in this region, despite only infecting a small proportion of animals (66/621, 10.62%). Occurrences of abortion and birth of weak calves were the only variables that showed as risk factors for the presence of N. caninum. The result from the spatial lag model strongly indicated that birth of weak calves and presence of N. caninum are occurring on farms that are located close to each other, indicating aggregation of disease occurrence.

    Cryptosporidium parvum is the most frequent parasitic agent that causes diarrhoea in AIDS patients in Thailand. Cryptosporidiosis outbreaks in humans may be attributed to contamination of their drinking water from infected dairy pastures. A 23-kDa glycoprotein of C. parvum (CpP23) is a sporozoite surface protein that is geographically conserved among C. parvum isolates. This glycoprotein is a potentially useful candidate antigen for the diagnosis of cryptosporidiosis by enzyme-linked immunosorbent assay. Therefore, we investigated the seroprevalence of C. parvum infection in dairy cows in northern Thailand using an ELISA based on recombinant CpP23 antigen. Sera were randomly collected from 642 dairy cows of 42 small-holder farmers, which had the top three highest number of the dairy cows' population in Northern Thailand, that included Chiang Mai, Chiang Rai and Lumpang provinces. The overall seroprevalence of the infection was 4.4%, and the seropositive rates for the three provinces were 3.3% in Chiang Mai, 5.1% in Chiang Rai and 3% in Lumpang. These results suggest that cattle could play a role in zoonotic cryptosporidiosis in Thailand.

    Infections with helminth parasites can negatively affect performance of dairy cows. Knowledge on infection intensity, spatial distributions and risk factors are key to develop targeted treatment strategies. Canada and most EU countries have conducted large investigations, but respective data for Switzerland were missing. We now performed a bulk tank milk serosurvey for Ostertagia ostertagi, Fasciola hepatica, and Dictyocaulus viviparus on a total of 1036 voluntarily participating dairy herds that were sampled at confinement periods, i.e. in winter 2014/15 or 2015/16, respectively. All samples were analyzed with commercial ELISAs for antibodies (AB) against O. ostertagi and F. hepatica, and those of the first sampling period additionally with an in-house ELISA for AB against D. viviparus. Testing for the latter parasite was not done in the second year of the study, as the sampling period might have missed infections due to the short lived nature of specific antibodies. The possible influence of geographic, climatic, and farm management variables on AB levels were assessed for each parasite using scanning cluster and multiple regression analysis. Overall seroprevalence for O. ostertagi was 95.5% (95% C.I.: 94.0-96.6), with a mean optical density ratio (ODR) of 0.83, for F. hepatica 41.3% (95% C.I.: 38.3-44.4), and for D. viviparus 2.9% (95% C.I.: 1.6-4.7). There were no significant differences between the two sampling periods. For all parasites, significant geographic clusters of higher AB levels could be established. Furthermore, AB levels against all three parasites were positively correlated with each other, indicating either cross-reactions or co-infections. For O. ostertagi, herd size and percentage of pasture in the ration were positively correlated with AB levels. For F. hepatica, altitude above sea level (a.s.l.) positively, and milk production per cow and year was negatively correlated with AB levels. This work provides baseline data for further

    Since its first occurrence in August 2011 in Germany and the Netherlands, the Schmallenberg virus (SBV) spread rapidly across Europe, where it caused production losses and abortions in ruminants as well as congenital malformations in the offspring of affected animals. Several studies have investigated the impact of SBV on fertility and production parameters in dairy cows at herd level. However, the impact of clinical disease at the animal level remained undetermined. This study aimed at estimating the impact of clinical disease during and after an infection with SBV on production and fertility parameters in individual Swiss dairy cows. Sixty-seven case and twenty-four control herds were selected according to whether cows had been showing clinical signs indicative of SBV during the epidemic from July to December 2012 in Switzerland. Of these 91 farms, production and fertility data from 388 cows with clinical signs from case herds were collected over a time period of four years, and compared to data from 932 cows without clinical signs originating from case or control herds. Milk yield, somatic cell count, number of inseminations and non-return at day 56 were analysed by means of hierarchical multivariable regression analysis. A significant drop in milk yield was observed in all groups during the SBV epidemic compared to the time before the infection, which amounted to 1.9kg per test day for clinical animals, 1.1kg for non-clinical animals from case herds and 0.6kg for non-clinical animals from control herds. A prolonged effect on milk yield was observed in clinical cows for about one year, suggesting that animals with clinical disease might not return to their previous milk production level in the current lactation after an acute infection with SBV. Clinical animals showed a significantly higher somatic cell count during the epidemic compared to the time before the infection. The number of inseminations per cow and production cycle was higher for clinical animals

    The correlation of Clostridium difficile infection (CDI) with in-hospital morbidity is important in hospital settings where broad-spectrum antimicrobial agents are routinely used, such as in Greece. The C. DEFINE study aimed to assess point-prevalence of CDI in Greece during two study periods in 2013. There were two study periods consisting of a single day in March and another in October 2013. Stool samples from all patients hospitalized outside the ICU aged ≥18 years old with diarrhea on each day in 21 and 25 hospitals, respectively, were tested for CDI. Samples were tested for the presence of glutamate dehydrogenase antigen (GDH) and toxins A/B of C. difficile; samples positive for GDH and negative for toxins were further tested by culture and PCR for the presence of toxin genes. An analysis was performed to identify potential risk factors for CDI among patients with diarrhea. 5,536 and 6,523 patients were screened during the first and second study periods, respectively. The respective point-prevalence of CDI in all patients was 5.6 and 3.9 per 10,000 patient bed-days whereas the proportion of CDI among patients with diarrhea was 17% and 14.3%. Logistic regression analysis revealed that solid tumor malignancy [odds ratio (OR) 2.69, 95% confidence interval (CI): 1.18-6.15, p = 0.019] and antimicrobial administration (OR 3.61, 95% CI: 1.03-12.76, p = 0.045) were independent risk factors for CDI development. Charlson's Comorbidity Index (CCI) >6 was also found as a risk factor of marginal statistical significance (OR 2.24, 95% CI: 0.98-5.10). Median time to CDI from hospital admission was shorter with the presence of solid tumor malignancy (3 vs 5 days; p = 0.002) and of CCI >6 (4 vs 6 days, p = 0.009). The point-prevalence of CDI in Greek hospitals was consistent among cases of diarrhea over a 6-month period. Major risk factors were antimicrobial use, solid tumor malignancy and a CCI score >6.

    Full Text Available Prevalence of intramammary infections at prepartum and postpartum in primigravid heifers from five dairy herds located in the central dairy area of Argentina was determined. Mammary secretion samples from 140 heifers (560 mammary quarters were obtained 14 days prior to the expected calving day and within 7 days after parturition and subjected to bacteriological analysis. No clinical mastitis cases were detected during the study. The number of infected heifers in at least one mammary quarter at pre and postpartum was 87 (62.2% and 53 (37.8%, respectively. The most prevalent mastitis pathogens at prepartum among samples yielding a positive bacteriological culture were coagulasenegative staphylococci (69.07%, Staphylococcus aureus (12.71% and Streptococcus uberis (4.42%. A decrease on isolation frequency of coagulase-negative staphylococci (53.41% and S. uberis (2.27% was observed at postpartum, while that of S. aureus showed an increase (21.59%. Presence of intramammary infections appeared to be associated with some management conditions. These results highlighted the need to improve diagnosis and control measures in replacement heifers.Se determinó la prevalencia al preparto y posparto de infecciones intramamarias causadas por organismos patógenos de mastitis en vaquillonas primíparas de cinco establecimientos lecheros ubicados en la cuenca central santafesina.

    Full Text Available The objective of the current research project was to document the prevalent helminths of dairy animals of Nestle milk collection areas of Punjab (Pakistan. For this purpose, seven high milk-producing areas of Punjab province including Farooqa, Kot Adu, Dunya Pur, Layyah, Mor Mandi, Shorkot and Jalapur were selected. The animals were randomly selected and screened for parasitic eggs through standard coprological examination procedures. The helminth species found prevalent in the study areas included; Ascaris vitulorum, Fasciola hepatica, Haemonchus contortus, Bunostomum phlebotomum, Ostertagia circumcinta, Oesophagostomum radiatum, and Trichostrongylus spp. The possible determinants associated with the prevalence of these parasites were also studied in this project. The results of this study provided a basic epidemiological data for planning a wide scaled helminth control program in the above-mentioned high producing areas of Pakistan.

    Staphylococcus chromogenes is a highly prevalent species in subclinical mastitis with a well-established impact on somatic cell count. Few data are available on its antimicrobial susceptibility. The objective of this study was three-fold: (1) to evaluate simple identification tests by comparing them with a genomic method; (2) to determine minimal inhibitory concentrations (MICs) of different antibiotics; (3) to search for the presence of important resistance mechanisms and resistance-determining genes.Seventy-three staphylococcal strains, all collected on different dairy farms, were tentatively identified as S. chromogenes based on their lack of hemolysis and their characteristic intermediate DNase activity. The identification of 70 strains was confirmed as S. chromogenes by tRNA intergenic spacer PCR (tRNA PCR). Three strains were identified as S. sciuri, a species that is naturally cloxacillin- and lincomycin-resistant. All 70 S. chromogenes strains were found to be normally susceptible to neomycin, gentamicin, erythromycin, enrofloxacin, and to penicillinase-stable penicillins and cephalosporins, represented in this study by cloxacillin. The latter result was confirmed by the absence of the mecA gene in each of 13 strains in which this gene was searched for. Twenty-seven (38%) strains were penicillinase producers. Three lincomycin-resistant S. chromogenes strains were found to carry the linA gene. It was concluded that S. chromogenes can be identified reliably in routine mastitis bacteriology, and that the only resistance of importance is against penicillinase-susceptible penicillins.

    Full Text Available Among the various systemic reactions against infection or injury, the acute phase response is the cascade of reaction and mostly coordinated by cytokines-mediated acute phase proteins (APPs production. Since APPs are sensitive innate immune molecules, they are useful for early detection of inflammation in bovines and believed to be better discriminators than routine hematological parameters. Therefore, the possibility of using APPs as a diagnostic and prognostic marker of inflammation in major bovine health disorders including postpartum uterine infection has been explored by many workers. In this review, we discussed specifically importance of postpartum uterine infection, the role of energy balance in uterine infections and potential of APPs as a predictor of postpartum uterine infections during the transition period and its regulatory mechanism in dairy cattle.

  19. Dairy Cows Naturally Infected with Bovine Leukemia Virus Exhibit Abnormal B- and T-Cell Phenotypes after Primary and Secondary Exposures to Keyhole Limpet Hemocyanin

    Bovine leukemia virus (BLV) is a retrovirus that is highly prevalent in US dairy herds: over 83% are BLV infected and the within-herd infection rate can be almost 50% on average. While BLV is known to cause lymphosarcomas, only 5% or fewer infected cattle will develop lymphoma; this low prevalence of cancer has historically not been a concern to dairy producers. However, more recent research has found that BLV+ cows without lymphoma produce less milk and have shorter lifespans than uninfected herdmates. It has been hypothesized that BLV infection interferes with normal immune function in infected cattle, and this could lead to reduced dairy production. To assess how naturally infected BLV+ cows responded to a primary and secondary immune challenge, 10 BLV+ and 10 BLV− cows were injected subcutaneously with keyhole limpet hemocyanin (KLH) and dimethyldioctadecylammonium bromide. B- and T-cell responses were characterized over the following 28 days. A total of 56 days after primary KLH exposure, cows were re-injected with KLH and B- and T-cell responses were characterized again over the following 28 days. BLV+ cows produced less KLH-specific IgM after primary immune stimulation; demonstrated fewer CD45R0+ B cells, altered proportions of CD5+ B cells, altered expression of CD5 on CD5+ B cells, and reduced MHCII surface expression on B cells ex vivo; exhibited reduced B-cell activation in vitro; and displayed an increase in BLV proviral load after KLH exposure. In addition, BLV+ cows had a reduced CD45R0+γδ+ T-cell population in the periphery and demonstrated a greater prevalence of IL4-producing T cells in vitro. All together, our results demonstrate that both B- and T-cell immunities are disrupted in BLV+ cows and that antigen-specific deficiencies can be detected in BLV+ cows even after a primary immune exposure.

    Full Text Available Between June 1999 and August 2000, the effects of feeding medicated urea-molasses supplement blocks on the growth of dairy heifers in a marginal area of central Kenya were assessed by comparing the live-weight gain of supplemented and unsupplemented heifers grazing the same pasture. Thirty-nine heifers with an average age of 9.6 months were initially treated orally with albendazole (10 mg / kg body weight and assigned to 3 groups : group I was fed urea-molasses blocks with incorporated fenbendazole (MUMB, group II was fed urea-molasses blocks (UMB and group III heifers (control received no block supplementation (NBS. Body weights of the heifers and faecal egg counts (FECs were measured monthly and larval cultures were made of positive faecal samples of each group. The mean cumulative live-weight responses of the MUMB and UMB groups were significantly greater than the NBS group (P 0.05. The FECs were moderate to low in all groups and decreased progressively with increasing age of the animals; FECs for the urea-molasses-supplemented groups remained significantly lower than those of the NBS group throughout the experimental period (P <0.05. Haemonchus and Trichostrongylus were the predominant nematode genera found in the heifers, but Cooperia, Bunostomum and Oesophagostomum were also present. These results indicate that feeding of urea-molasses blocks substantially reduced production losses attributable to nematode infection of young grazing cattle, and confirms previous observations that well-fed animals are better able to overcome the effects of helminth infections.

    Objectives of this study were to identify the manageable risk factors associated with the lactational incidence, elimination, and prevalence of coagulase-negative staphylococci (CNS) intramammary infections (IMI) while taking into account the difficulties inherent to their diagnosis. A second objective was to evaluate the effect of CNS IMI misclassification in mastitis research. A cohort of 90 Canadian dairy herds was followed throughout 2007 to 2008. In each herd, series of quarter milk samples were collected from a subsample of cows and bacteriological culture was performed to identify prevalent, incident, and eliminated CNS IMI. Practices used on farms were captured using direct observations and a validated questionnaire. The relationships between herd CNS IMI prevalence and herd incidence and elimination rates were explored using linear regression. Manageable risk factors associated with the prevalence, incidence, or elimination of CNS IMI were identified via Bayesian analyses using a latent class model approach, allowing adjustment of the estimates for the imperfect sensitivity and specificity of bacteriological culture. After adjustment for the diagnostic test limitations, a mean CNS IMI quarter prevalence of 42.7% [95% confidence interval (CI): 34.7, 50.1] and incidence and elimination rates of 0.29 new IMI/quarter-month (95% CI: 0.21, 0.37) and 0.79 eliminated IMI/quarter-month (95% CI: 0.66, 0.91), respectively, were observed. Considerable biases of the estimates were observed when CNS IMI misclassification was ignored. These biases were important for measures of association with risk factors, were almost always toward the null value, and led to both type I and type II errors. Coagulase-negative staphylococci IMI incidence appeared to be a stronger determinant of herd IMI prevalence than IMI elimination rate. The majority of herds followed were already using blanket dry cow treatment and postmilking teat disinfection. A holistic approach considering

  6. Ancient Greek Calendars

    Science.gov (United States)

    Hannah, Robert

    Greek festival calendars were in origin lunar, eventually being aligned with the sun through various lunisolar intercalary cycles. Each city-state had its own calendar, whose month names have some, little, or no similarity with those of other city-states. These names often reflect gods or festivals held in their honor in a given month, so there is an explicitly sacred character to the calendar. New Year's Day could also differ from one state to another, but generally began with the sighting of the first new moon after one of the four tropical points. Even the introduction of the Roman Julian calendar brought little uniformity to the eastern Greek calendars. The calendar is one of the elements which can assist in understanding the siting of Greek sacred structures.

    Whether response to combination antiretroviral therapy (cART) differs between those infected with HIV-1 subtype A or B remains unclear. We compared virological and immunological response to cART in individuals infected with subtype A or B in an ethnically homogeneous population. Data derived from the Athens Multicenter AIDS Cohort Study (AMACS) and analysis were restricted to those of Greek origin. Time to virological response (confirmed HIV-RNA 500 copies/ml at any time or no response by month 6) were analyzed using survival models and CD4 changes after cART initiation using piecewise linear mixed effects models. Of the 571 subjects included in the analysis, 412 (72.2%) were infected with subtype B and 159 (27.8%) with subtype A. After adjusting for various prognostic factors, the rate of virological response was higher for those infected with subtype A versus B (adjusted HR: 1.35; 95% CI: 1.08-1.68; p=0.009). Subtype A was also marginally associated with a lower hazard of virological failure compared to subtype B (HR=0.73; 95% CI: 0.53-1.02; p=0.062). Further adjustment for treatment adherence did not substantially changed the main results. No significant differences were observed in the rates of CD4 increases by subtype. The overall median (95% CI) CD4 increase at 2 years of cART was 193 (175, 212) cells/μl. Our study, based on one of the largest homogeneous groups of subtype A and B infections in Europe, showed that individuals infected with subtype A had an improved virological but similar immunological response to cART compared to those infected with subtype B.

    Reproductive tract bacterial infections, particularly those caused by Escherichia coli and Trueperella pyogenes, can have a negative impact on reproductive performance. It has been hypothesized that the presence of E coli early postpartum may increase the risk of isolation of T pyogenes later postpartum. The objective of the present study was to examine associations between intrauterine bacterial infections with E coli and T pyogenes and any bacterial growth (irrespective of bacterial species), purulent vaginal discharge (PVD), cytologic evidence of endometritis (an increased proportion of polymorphonuclear cells [PMNs]), and reproductive performance. Dairy cows (n = 272) from six herds were examined at Days 0 (median, 2 days in milk), 21 and 42 postpartum. From each cow two intrauterine samples were collected via triple-guarded cytobrush at Days 0 and 21. The first cytobrush was used for bacteriologic culture. Escherichia coli and T pyogenes were isolated by culture, and E coli isolates were assigned to one of four phylogenetic groups using a two-step triplex polymerase chain reaction. In addition, T pyogenes was confirmed by polymerase chain reaction. The second cytobrush was used to prepare a cytology slide. Nucleated cells (n = 200) were categorized as epithelial cells, PMNs, or macrophages. Cows were also assessed for body condition score, PVD score, the presence of a CL, and pregnancy. Statistical analysis was performed using multivariable models. There was no association between the presence of E coli at Day 0 and probability of isolation of T pyogenes 3 weeks later; however, E coli positive cows at Day 0 were more likely to be diagnosed with E coli at Day 21 (relative risk [RR] = 2.0, P bacterial growth at Day 21, irrespective of species, were less likely to conceive within 3 weeks after the start of the seasonal breeding program (RR = 0.8; P = 0.05). Interestingly, cows with 25% PMNs or greater at Day 0 had shorter time to pregnancy (hazard ratio = 1.32; P

    An increase in veterinary and farmer interest in bovine viral diarrhoea (BVD) in New Zealand over recent years led to requests for cost-effective identification of BVD virus (BVDV) infected herds and individuals. This study was undertaken to determine if the use of real-time reverse transcriptase polymerase chain reaction (RT-PCR) technology and dairy cow production data could identify persistently infected (PI) animals in milking herds. Milk samples were collected from the vats of dairy herds and tested for the presence of BVDV by RT-PCR till four herds were found containing PI animals. Individual serum samples were then collected from every cow in the herd and tested by both RT-PCR and antigen capture enzyme-linked immunosorbent assays (ACE) to identify the PI animals. Individual animal testing found 1/223, 1/130, 2/800 and 1/275 PI's respectively in the four herds. Based on these results a maximum pool size of 400 cows contributing to the bulk tank milk was selected. After removal of the PI from the herds, further bulk milk samples were shown to be BVDV negative by RT-PCR. All the PI animals identified by this method were found in the lowest producing 10-20% of herd. This approach of targeted testing of dairy herds using PCR technology, in conjunction with animal production information, markedly reduced the cost of diagnostic testing for BVDV in dairy herds in New Zealand. Questionnaire follow-up on 81 BVDV-positive herds (15% of those tested) indicated the stratification approach identified milking PIs successfully over 90% of the time and reduced the number of individual tests to 12% of the milking herd.

    The objective of this paper is to evaluate the microbiological state and the dynamics of the mammary infections of organic farms in North Spain to discover if the high somatic cell count (SCC) observed in these farms is associated to a high incidence of mastitis. Microbiological cultures and SCC were performed in 8,496 foremilk samples collected from 160 cows in five representative organic farms from February 2006 to January 2008. Even though 79.3% of cultures were positive, only 21.2% of the total fit our diagnosis of mastitis (clinical, subclinical and chronic). The great prevalence of Corynebacterium bovis (teat canal-region pathogen) in the positive cultures that did not fit the mastitis diagnosis criteria (nearly 70%) compared with those that did (27%) was found to be related to lack of post-milking teat disinfection. The study prevalence of mastitis was 69.2% (66.7% subclinical mastitis, 27.8% clinical mastitis); the mean monthly prevalence was 47.4%; the mean monthly incidence was 12.9% and the mean duration of infection was 3.84 ± 3.98 months The high SCC in foremilk samples from old cows (three or more lactations) not diagnosed as mastitis compared to the heifers, reflects a worsening health status of the animals over time. When compared with the conventional sector in Northern Spain, these parameters indicate a poorer udder health in the studied organic herds with a high presence of chronic subclinical processes.

    Full Text Available Abstract Background Acute phase proteins haptoglobin (Hp, serum amyloid A (SAA and lipopolysaccharide binding protein (LBP have suggested to be suitable inflammatory markers for bovine mastitis. The aim of the study was to investigate acute phase markers along with clinical parameters in two consecutive intramammary challenges with Escherichia coli and to evaluate the possible carry-over effect when same animals are used in an experimental model. Methods Mastitis was induced with a dose of 1500 cfu of E. coli in one quarter of six cows and inoculation repeated in another quarter after an interval of 14 days. Concentrations of acute phase proteins haptoglobin (Hp, serum amyloid A (SAA and lipopolysaccharide binding protein (LBP were determined in serum and milk. Results In both challenges all cows became infected and developed clinical mastitis within 12 hours of inoculation. Clinical disease and acute phase response was generally milder in the second challenge. Concentrations of SAA in milk started to increase 12 hours after inoculation and peaked at 60 hours after the first challenge and at 44 hours after the second challenge. Concentrations of SAA in serum increased more slowly and peaked at the same times as in milk; concentrations in serum were about one third of those in milk. Hp started to increase in milk similarly and peaked at 36–44 hours. In serum, the concentration of Hp peaked at 60–68 hours and was twice as high as in milk. LBP concentrations in milk and serum started to increase after 12 hours and peaked at 36 hours, being higher in milk. The concentrations of acute phase proteins in serum and milk in the E. coli infection model were much higher than those recorded in experiments using Gram-positive pathogens, indicating the severe inflammation induced by E. coli. Conclusion Acute phase proteins would be useful parameters as mastitis indicators and to assess the severity of mastitis. If repeated experimental intramammary

    Focusing his analysis on (mostly Athenian) vase paintings of the sixth- and early fifth-century and on a handful of texts from the late fifth- and early fourth-century (again Athenian), Dover depicted the pederastic relationship of erastes (age 20 to 30) and eromenos (age 12-18) as defined by sexual roles, active and passive, respectively. This dichotomy he connected to other sexual and social phenomena, in which the active/ penetrating role was considered proper for a male adult Athenian citizen, while the passive/penetrated role was denigrated, ridiculed, and even punished. Constructing various social and psychological theories, Foucault and Halperin, along with a host of others, have extended his analysis, but at the core has remained the Dover dogma of sexual-role dichotomization. Penetration has become such a focal point in the scholarship that anything unable to be analyzed in terms of domination is downplayed or ignored. To reduce homosexuality or same-sex behaviors to the purely physical or sexual does an injustice to the complex phenomena of the Greek male experience. From Sparta to Athens to Thebes and beyond, the Greek world incorporated pederasty into their educational systems. Pederasty became a way to lead a boy into manhood and full participation in the polis, which meant not just participation in politics but primarily the ability to benefit the city in a wide range of potential ways. Thus the education, training, and even inspiration provided in the pederastic relationship released creative forces that led to what has been called the Greek 'miracle.' From around 630 BCE we find the institution of Greek pederasty informing the art and literature to a degree yet to be fully appreciated. Moreover, this influence not only extends to the 'higher' realms of culture, but also can be seen stimulating society at all levels, from the military to athletic games, from philosophy to historiography. An understanding of sexual practices-useful, even essential, to

    Group G streptococci in animals usually belong to the species Streptococcus canis and are most commonly found in dogs and cats. Occasionally, Strep. canis is detected in milk from dairy cows. An outbreak of Strep. canis mastitis in a dairy herd is described. Based on results from bacterial culture and ribotyping, a cat with chronic sinusitis was the most likely source of the outbreak. Subsequent cow-to-cow transmission of Strep. canis was facilitated by poor udder health management, including...

    Full Text Available The objective of this investigation was to evaluate whether intravaginal infusion of a lactic acid bacteria (LAB cocktail around parturition could influence the immune response, incidence rate of uterine infections, and the overall health status of periparturient dairy cows. One hundred pregnant Holstein dairy cows were assigned to 1 of the 3 experimental groups as follows: 1 one dose of LAB on wk -2 and -1, and one dose of carrier (sterile skim milk on wk +1 relative to the expected day of parturition (TRT1; 2 one dose of LAB on wk -2, -1, and +1 (TRT2, and 3 one dose of carrier on wk -2, -1, and +1 (CTR. The LAB were a lyophilized culture mixture composed of Lactobacillus sakei FUA3089, Pediococcus acidilactici FUA3138, and Pediococcus acidilactici FUA3140 with a cell count of 108-109 cfu/dose. Blood samples and vaginal mucus were collected once a week from wk -2 to +3 and analyzed for content of serum total immunoglobulin G (IgG, lipopolysaccharide-binding protein (LBP, serum amyloid A (SAA, haptoglobin (Hp, tumor necrosis factor (TNF, interleukin (IL-1, IL-6, and vaginal mucus secretory IgA (sIgA. Clinical observations including rectal temperature, vaginal discharges, retained placenta, displaced abomasum, and laminitis were monitored from wk -2 to +8 relative to calving. Results showed that intravaginal LAB lowered the incidence of metritis and total uterine infections. Intravaginal LAB also were associated with lower concentrations of systemic LBP, an overall tendency for lower SAA, and greater vaginal mucus sIgA. No differences were observed for serum concentrations of Hp, TNF, IL-1, IL-6 and total IgG among the treatment groups. Administration with LAB had no effect on the incidence rates of other transition cow diseases. Overall intravaginal LAB lowered uterine infections and improved local and systemic immune responses in the treated transition dairy cows.

    Common infectious diseases (CID) of the airways and the gastrointestinal tract are still a considerable cause of morbidity and mortality in elderly. The present study examined the beneficial effect of a dairy product containing the probiotic strain Lactobacillus casei DN-114 001 (fermented product) on the resistance of free-living elderly to CID. The study was multicentric, double blind and controlled, involving 1072 volunteers (median age = 76.0 years) randomised for consumption of either 200 g/d of fermented (n 537) or control (non-fermented) dairy product (n 535) for 3 months, followed by an additional 1 month's follow-up. The results showed that, when considering all CID, the fermented product significantly reduced the average duration per episode of CID (6.5 v. 8 d in control group; P = 0.008) and the cumulative duration of CID (7 v. 8 d in control group; P = 0.009). Reduction in both episode and cumulative durations was also significant for all upper respiratory tract infections (URTI; P fermented product consumption (2-3.8 x 107 equivalents of colony-forming unit/g of stools, P fermented product was safe and well tolerated. In conclusion, consumption of a fermented dairy product containing the probiotic strain L. casei DN-114 001 in elderly was associated with a decreased duration of CID in comparison with the control group, especially for URTI such as rhinopharyngitis.

    Mycobacterium avium ssp. paratuberculosis (MAP), the causative agent of ruminant Johne's disease, presents a particular challenge with regard to infection mitigation on dairy farms. Diagnostic testing strategies to identify and quantify MAP and associated antibodies are imperfect, and certain facets of the relationship between diagnostic tests remain to be explored. Additional repeated-measures data from known infected animals are needed to complement the body of cross-sectional research on Johne's disease-testing methods. Statistical models that accurately account for multiple diagnostic results while adjusting for the effects of individual animals and herds over time can provide a more detailed understanding of the interplay between diagnostic outcomes. Further, test results may be considered as continuous wherever possible so as to avoid the information loss associated with dichotomization. To achieve a broader understanding of the relationship between diagnostic tests, we collected a large number of repeated fecal and milk samples from 14 infected cows, in addition to bulk milk samples, from 2 low-prevalence dairy herds in the northeast United States. Predominately through the use of mixed linear modeling, we identified strong associations between milk ELISA optical density, fecal quantitative PCR, and fecal culture in individual animals while concurrently adjusting for variables that could alter these relationships. Notably, we uncovered subtleties in the predictive abilities of fecal shedding level on milk ELISA results, with animals categorized as disease progressors reaching higher ELISA optical density levels. Moreover, we observed that spikes in fecal shedding could predict subsequent high ELISA values up to 2 mo later. We also investigated the presence of MAP in individual milk samples via PCR and noted an association between poor udder hygiene and MAP positivity in milk, suggesting some level of environmental contamination. The paucity of positive milk

    Full Text Available Bluetongue virus (BTV is the cause of an economically important arboviral disease of domestic and wild ruminants. The occurrence of BTV infection of livestock is distinctly seasonal in temperate regions of the world, thus we determined the dynamics of BTV infection (using BTV-specific real time reverse transcriptase polymerase chain reaction among sentinel cattle and vector Culicoides sonorensis (C. sonorensis midges on a dairy farm in northern California throughout both the seasonal and interseasonal (overwintering periods of BTV activity from August 2012 until March 2014. The data confirmed widespread infection of both sentinel cattle and vector midges during the August-November period of seasonal BTV transmission, however BTV infection of parous female midges captured in traps set during daylight hours also was detected in February of both 2013 and 2014, during the interseasonal period. The finding of BTV-infected vector midges during mid-winter suggests that BTV may overwinter in northern California by infection of long-lived female C. sonorensis midges that were infected during the prior seasonal period of virus transmission, and reemerged sporadically during the overwintering period; however the data do not definitively preclude other potential mechanisms of BTV overwintering that are also discussed.

    Full Text Available Abstract Background Staphylococcus aureus is one of the most common causes of intramammary infections in dairy cows at dry off. Reliable identification is important for disease management on herd level and for antimicrobial treatment of infected animals. Our objective was to evaluate the test characteristics of PathoProof ™ Mastitis PCR Assay and bacteriological culture (BC in diagnosing bovine intramammary infections caused by S. aureus at dry off at different PCR cycle threshold (Ct-value cut-offs. Methods Sterile quarter samples and non-sterile composite samples from 140 animals in seven herds were collected in connection with the dairy herd improvement (DHI milk recording. All quarter samples were analyzed using BC whereas all composite samples were analyzed with PathoProof ™ Mastitis PCR Assay. Latent class analysis was used to estimate test properties for PCR and BC in the absence of a perfect reference test. The population was divided into two geographically divided subpopulations and the Hui-Walter 2-test 2-populations model applied to estimate Se, Sp for the two tests, and prevalence for the two subpopulations. Results The Se for PCR increased with increasing Ct-value cut-off, accompanied by a small decrease in Sp. For BC the Se decreased and Sp increased with increasing Ct-value cut-off. Most optimal test estimates for the real-time PCR assay were at a Ct-value cut-off of 37; 0.93 [95% posterior probability interval (PPI 0.60-0.99] for Se and 0.95 [95% PPI 0.95-0.99] for Sp. At the same Ct-value cut-off, Se and Sp for BC were 0.83 [95% PPI 0.66-0.99] and 0.97 [95% PPI 0.91-0.99] respectively. Depending on the chosen PCR Ct-value cut-off, the prevalence in the subpopulations varied; the prevalence increased with increasing PCR Ct-value cut-offs. Conclusion Neither BC nor real-time PCR is a perfect test in detecting IMI in dairy cows at dry off. The changes in sensitivity and prevalence at different Ct-value cut-offs for both PCR and

    The smooth functioning of an ordered society depends on the possession of a means of regularising its activities over time. That means is a calendar, and its regularity is a function of how well it models the more or less regular movements of the celestial bodies - of the moon, the sun or the stars. Greek and Roman Calendars examines the ancient calendar as just such a time-piece, whose elements are readily described in astronomical and mathematical terms. The story of these calendars is one of a continuous struggle to maintain a correspondence with the regularity of the seasons and the sun, d

    Coagulase-negative staphylococci (CNS) are frequently isolated from quarters with subclinical mastitis, teat apices, and the cows' environment. Virulence, ecology, epidemiological behavior, and effect on udder health vary between different CNS species. Staphylococcus chromogenes, Staph. simulans, and Staph. xylosus are frequently present in milk and have a more substantial effect on quarter milk somatic cell count than other species. Therefore, these species are considered the "more relevant" CNS. As species-specific factors associated with CNS intramammary infection (IMI) have not yet been identified and susceptibility for IMI differs between cows and quarters, this study aimed to identify predictors for CNS IMI at the cow and quarter level (some of them changing over time) with a specific focus on the aforementioned more relevant CNS. Precise data were available from a longitudinal study (3,052 observations from 344 quarters from 86 dairy cows belonging to 3 commercial dairy herds). All CNS were molecularly identified to the species level, and multivariable, multilevel logistic regression models taking into account the longitudinal nature of the data, were fit to study the likelihood of infection. Staphylococcus chromogenes, Staph. xylosus, and Staph. cohnii were the most frequently isolated species from CNS IMI in older cows, whereas Staph. chromogenes, Staph. xylosus, and Staph. simulans were the main species found in IMI in heifers. Quarters from heifers (as opposed to multiparous cows), from heifers and multiparous cows in third or fourth month in lactation (as opposed to early lactation, <60 d in milk), and with an increasing quarter milk SCC were more likely to be infected with the more relevant CNS species. Quarter milk SCC was identified as the sole statistically significant predictor for IMI with other CNS species, although the size of the effect was lower [odds ratio of 1.6 (1.4-1.9) vs. 2.1 (1.8-2.5)] than the effect for IMI with the more relevant CNS

    The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data. Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12 syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the Simplified Nasometric Assessment Procedures Test (SNAP test) test ( MacKay and Kummer, 1994 ) in Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males (mean age = 21 years) and 40 females (mean age = 20.5 years), with normal hearing and speech characteristics and unremarkable history were included in the study. The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance scores than other languages examined in past work. The aforementioned normative data on nasalance of young adult speakers of Greek are valid across gender and have direct clinical utility as they provide valuable reference information for the diagnosis and management of Greek adults with resonance disorders caused by velar dysfunction.

    Full Text Available Six hundred and thirty clinically-normal milk samples from dairy goat flocks comprising a mixed population of German Alpine, Toggenburg, Saanen and Galla crosses were exam-ined over a 3-month period to determine the prevalence of bacterial organisms. Bacteria were isolated in 28.7 % of the milk samples (181/630 either singly (92.8 % or in combination (7.2 %. The most prevalent bacterial organisms were Staphylococcus spp. (60.3 %, followed by Micrococcus spp. (17.7 %, Acinetobacter spp. (5 %, Actinomyces spp. (5% and Streptococcus spp. (1.1 %. The Staphylococcus spp. were mainly coagulase negative (64.3 %. Coagulase-- negative staphylococci and coagulase-positive staphylococci accounted for 37.5 % and 22.7 % respectively of the total bacteria isolated. The isolation of bacteria, some of which are important in clinical and subclinical mastitis, in apparently normal caprine milk, indicates that particular attention should be given to the management of these dairy goat flocks in order to avoid the development of cases of clinical mastitis.

Antibiotic susceptibility testing was performed by the disk diffusion method and E-test. Resistance genes (mecA in staphylococci; vanA/vanB/vanC in enterococci; bla KPC /bla VIM /bla NDM in Klebsiella spp.) were detected by PCR. In total, 4607 (9.7%) blood cultures were positive from 47451 sets sent to Department of Microbiology, representing 1732 BSIs. Gram-negative bacteria (52.3%) were the most commonly isolated, followed by Gram-positive (39.5%), fungi (6.6%) and anaerobes bacteria (1.8%). The highest contamination rate was observed among Gram-positive bacteria (42.3%). Among 330 CNS and 150 Staphylococcus aureus, 281 (85.2%) and 60 (40.0%) were mecA-positive, respectively. From 113 enterococci, eight were vanA, two vanB and two vanC-positives. Of the total 207 carbapenem-resistant Klebsiella pneumoniae (73.4%), 202 carried bla KPC , four bla KPC and bla VIM and one bla VIM . A significant increase in monthly BSIs' incidence was shown (R2: 0.449), which may be attributed to a rise of Gram-positive BSIs (R2: 0.337). Gram-positive BSIs were less frequent in spring (P period. The increasing incidence of BSIs can be attributed to an increase of Gram-positive BSI incidence, even though Gram-negative bacteria remained the predominant ones. Seasonality may play a role in the predominance of Gram-negative's BSI.

    The prevalence of bovine fasciolosis in Denmark is increasing but appropriate guidelines for control are currently lacking. In order to help develop a control strategy for liver fluke, a risk factor study of farm management factors was conducted and the utility of bulk tank milk (BTM ELISA) as a tool for diagnosis in Danish dairy cattle farms was assessed. This case-control study aimed to identify farm-level risk factors for fasciolosis in Danish dairy farms (> 50 animals slaughtered in 2013) using two diagnostic methods: recordings of liver condemnation at slaughter, and farm-level Fasciola hepatica antibody levels in BTM. A case farm was defined as having a minimum of 3 incidents of liver condemnation due to liver fluke at slaughter (in any age group) during 2013, and control farms were located within 10 km of at least one case farm and had no history of liver condemnation due to liver fluke during 2011-2013. The selected farmers were interviewed over telephone about grazing and control practices, and BTM from these farms was collected and analysed by ELISA in 2014. The final complete dataset consisting of 131 case and 63 control farms was analysed using logistic regression. Heifers grazing on wet pastures, dry cows grazing on wet pastures, herd size, breed and concurrent beef cattle production were identified as risk factors associated with being classified as a case farm. With the categorised BTM ELISA result as the response variable, heifers grazing on wet pastures, dry cows grazing on wet pastures, and purchase of cows were identified as risk factors. Within the case and control groups, 74.8 and 12.7% of farms were positive for fasciolosis on BTM ELISA, respectively. The differences are likely to be related to the detection limit of the farm-level prevalence by the BTM ELISA test, time span between slaughter data and BTM, and the relatively low sensitivity of liver inspection at slaughter. Control of bovine fasciolosis in Denmark should target heifers and

    With the aim of evaluating the effect of a Mongolian dairy product derived Lactobacillus paracasei spp. paracasei (strain 06TCa22) (Lpp) on the cytokine-mediated immune responses to Vibrio harveyi infection, we examined 16 cytokine expressions in the Japanese pufferfish, Takifugu rubripes. Fish were orally treated with the heat-killed Lpp at 1 mg g(-1) body weight d(-1) for 3 days. At 24 h posttreatment, fish were infected by an intramuscular injection of 0.1 mL V. harveyi bacterial suspension (10(8) cfu mL(-1)). Additionally, superoxide anion production (SAP) and phagocytic activity (PA) of head kidney cells were assessed during 120 h postinfection period. Significant up-regulation of pro-inflammatory (IL-1β, IL-6, IL-17A/F-3, TNF-α and TNF-N), cell-mediated immune inducing (IL-12p35, IL-12p40 and IL-18), antiviral/intra-cellular pathogen killing (I-IFN-1 and IFN-γ), anti-inflammatory (IL-10) and lymphocyte agonistic (IL-2, IL-7, IL-15, IL-21 and TGF-β1) cytokines was observed in the treated fish compared to control ones during the pathogen infection. Furthermore, significantly increased SAP and PA (P < 0.01; 0.05) were recorded in the treated fish compared to untreated fish. These results suggest the beneficial role of Lpp in enhancement of cytokine-mediated immunity in the Japanese pufferfish against V. harveyi infection and application of this product as a potential fish immunostimulant.

    The standing and lying behavior patterns of dairy cows, particularly the length of time cows spend standing after milking, have the potential to influence the incidence of intramammary infection (IMI). The objectives were to describe the standing and lying behavior patterns of cows milked with an automatic milking system (AMS) and to determine how these patterns relate to the incidence of IMI. One hundred and eleven lactating Holstein dairy cows were monitored over a 4-mo period. These cows were kept in a sand-bedded freestall barn with 2 pens, each with a free cow traffic AMS. Feed was delivered once daily, and pushed up 2 to 3 times daily. Quarter milk samples were collected for bacteriological culture from each cow once every 4 wk. A new IMI was defined as a positive culture sample following a negative culture. For 7 d before each of the last 3 milk samplings, standing and lying behavior, and times of milking and feed manipulation (feed delivery and push up) were recorded. Daily lying time and lying bout length were negatively related with milk yield (r=-0.23 and -0.20, respectively) and milking frequency (r=-0.32 and -0.20, respectively); milk yield was positively related to milking frequency (r=0.58). Feed manipulation near the time cows were milked (1h before 2h after) resulted in the longest post-milking standing times (mean=86 min; 95% confidence interval=78, 94 min), whereas feed manipulation occurring outside that time frame resulted in shorter post-milking standing times. Over the study period, 171 new IMI were detected. Of these new IMI detected, those caused by coagulase-negative staphylococci were the only ones associated with post-milking standing time; as post-milking standing time increased past 2.5h after milking, the odds of acquiring a new IMI tended to also increase. In summary, standing and lying behavior patterns of cows milked with an AMS were affected by both feed manipulation and their milking activity. Further, the post-milking standing

    Greek yoghurt, a popular dairy product, generates large amounts of acid whey as a by-product during manufacturing. Post-processing treatment of this stream presents one of the main concerns for the industry. The objective of this study was to manipulate initial milk total solids content (15, 20 or 23 g/100 g) by addition of milk protein concentrate, thus reducing whey expulsion. Such an adjustment was investigated from the technological standpoint including starter culture performance, chemical and physical properties of manufactured Greek yoghurt and generated acid whey. A comparison was made to commercially available products. Increasing protein content in regular yoghurt reduced the amount of acid whey during whey draining. This protein fortification also enhanced the Lb. bulgaricus growth rate and proteolytic activity. Best structural properties including higher gel strength and lower syneresis were observed in the Greek yoghurt produced with 20 g/100 g initial milk total solid compared to manufactured or commercially available products, while acid whey generation was lowered due to lower drainage requirement.

    This paper reports the results of a comparison of the rates of psychiatric disorder from three general population surveys in which the PSE-ID-CATEGO system was used for case-definition. These surveys were of an English sample in Camberwell, London, and of two Greek samples, the first in Athens, the second of Greek Cypriot immigrants living in Camberwell. The results show that the rates of psychiatric disorders in both Greek samples were somewhat higher than those of the Camberwell population, the differences being accounted for by higher rates of anxiety disorders, especially in women. Comparisons in terms of syndrome profiles showed that Greeks reported more symptoms of generalized anxiety than their English counterparts who, in their turn, reported higher rates of obsessive symptoms, and symptoms of social anxiety. The higher rates in the Greek samples were possibly due to an increased frequency of non-specific neurotic symptoms like worrying and tension. The results of other European community surveys with the PSE suggest that there might be a genuine and general North-South difference in the expression of psychological distress. Cultural differences in terms of personality traits and culturally sanctioned child rearing practices might account for the findings.

    Full Text Available From an animal health-well being, welfare, and performance perspective, the postpartum period is comprised of an early window where acute health and cow survival is an issue with the development of septic metritis. Subsequently, sustained presence of endometritis is likely to be contributing to sub-fertility in lactating dairy cows with an overall herd pregnancy rate of approximately 16%. The challenge is to integrate on commercial dairies preventive medicine programs with reproductive management to improve herd fertility. Cows affected by periparturient disorders such as hypocalcemia, dystocia, and retained fetal membranes are more likely to contract uterine infections than cows that calve normally are. Thus, appropriate management of the transition period is critical in the prevention of uterine infections at the herd level. In addition, a postpartum program to monitor health to provide treatment to cows in the early stages of disease should be implemented.Desde el punto de vista del bienestar animal y de la perspectiva de productividad, el periodo postparto puede estar comprometido por una pequeña ventana durante el postparto temprano, en la cual la salud y supervivencia de las vacas es un problemática, debido a la presentación de metritis séptica. Esta se perpetuán subsecuentemente con la presentación de endometritis, la cual muy posiblemente contribuye con los patrones de sub-fertilidad en vacas lactantes, generando en general bajas tasas de preñez del 16 %. El reto es entonces integrar en las explotaciones comerciales un programa de medicina veterinaria preventiva con el manejo reproductivo, con el fin de mejorar la fertilidad del hato. Se ha descrito que las vacas que sufren problemas durante el periparto tales como hipocalcemia y retención de las membranas fetales son más susceptibles de contraer infecciones uterinas, comparadas con aquellas vacas que tienen un parto normal. Por ello un manejo apropiado del periodo de transici

    Using a natural exposure trial design, the goal of our study was to evaluate the clinical efficacy of an iodine teat disinfectant with barrier properties and a high level of free iodine relative to a conventional iodine teat disinfectant with no barrier properties and low levels of free iodine. During the 18 wk of the trial, quarter milk samples were collected every 2 wk from 385 dairy cows from 2 herds. Cows on both farms were assigned in a balanced way according to milk yield, number of lactation, days in milk, somatic cell count (SCC) and microbiology culture pretrial into one of following groups: nonbarrier post milking teat disinfectant (NBAR; n = 195 cows; 747 quarters) or barrier postmilking teat disinfectant (BAR; n = 190 cows; 728 quarters). Afterward, at each scoring date every 2 wk, milk SCC was quantified in samples from all mammary quarters and microbiologic culture was only performed on milk samples with SCC >200,000 cells/mL for multiparous cows and SCC >100,000 cells/mL for primiparous cows. A new intramammary infection (NIMI) was defined when a quarter had milk SCC 200,000 cells/mL for multiparous cows and >100,000 cells/mL for primiparous cows, and positive microorganism isolation. A quarter could have several NIMI, but only 1 case per specific pathogen was considered. The most frequently isolated microorganism group on both farms was Streptococcus spp. (6.25% of total mammary quarters), followed by coagulase-negative staphylococci (3.6%) and Corynebacterium spp. (1.5%). In the present study, an interaction occurred between treatment and week of trial on the incidence risk of NIMI. Quarters disinfected with BAR had 54 and 37% lower odds of NIMI than quarters disinfected with NBAR at 8 and 16 wk of the trial, respectively; whereas at other weeks of the study both products had similar incidence risks of NIMI. Overall, teats disinfected with BAR had 46% lower odds of acquiring a clinical mastitis than those disinfected with NBAR. We concluded that

    Full Text Available The present paper examines the issue of the Greek public debt. After providing a historical discussion, we show that the austerity of the last six years has been unsuccessful in stabilizing the debt while, at the same time, it has taken a heavy toll on the economy and society. The recent experience shows that the public debt is unsustainable and therefore a restructuring is needed. An insistence on the current policies is not justifiable either on pragmatic or on moral or any other grounds. The experience of Germany in the early post-WWII period provides some useful hints for the way forward. A solution to the public debt problem is a necessary but not sufficient condition for the solution of the Greek and European crisis. A wider agenda that deals with the malaises of the Greek economy and the structural imbalances of the Eurozone is of vital importance.

    Q fever is a worldwide zoonotic disease caused by Coxiella burnetii (C. burnetii), an obligate intracellular bacterium. In ruminants, shedding into the environment mainly occurs during parturition or abortion, but the bacterium is shed also in milk, vaginal mucus, stools and urine. In Italy few surveys have been conducted and reported seroprevalence values ranged between 10% and 60%, even if few human cases have been described. Genotyping of bacteria is crucial for enhancing diagnostic methods and for epidemiological surveillance. The objective of this study was to investigate genotypic differences of C. burnetii genotypes directly in 34 samples, collected during a 3-years survey among 11 dairy cattle and 11 goat farms in the north-eastern part of Italy using a 6-locus multiple loci variable number of tandem repeat analysis (MLVA) method. The samples analysed included 13 bulk tank milk (BTM), 6 individual milk, 11 vaginal swabs and 4 foetal spleens. MLVA-type 2 was determined as the most prevalent in cattle in this study. C. burnetii strains circulating in the studied cattle population are very similar to genotypes previously described, while genotypes from goats showed an important variability. Further investigation are needed to understand the reason of this pattern. Copyright © 2015 Institut Pasteur. Published by Elsevier Masson SAS. All rights reserved.

    This work was conducted to estimate the seroprevalence, to identify potential factors that influence seroprevalence of bovine viral diarrhea virus (BVDV), and to investigate the association between BVDV serostatus and occurrence of reproductive disorders in dairy cattle in three milksheds in Ethiopia. A total of 1379 serum samples were obtained from cattle randomly selected from 149 herds from three milksheds representing central, southern, and western Ethiopia. Sera samples were examined for bovine viral diarrhea virus (BVDV) antibodies using commercial competitive enzyme-linked immunosorbent assay (ELISA) kit. Logistic regression analysis was employed to investigate associations between risk factors and the risk of BVDV seroprevalence, and BVDV serostatus and reproductive disorders. Seroreaction to BVDV antigens was detected in 32.6% of the 1379 cattle and 69.8% of the 149 herds sampled. Factors associated with BVDV seroplevalence were age, breed, and herd size (P  0.05). Risk of reproductive disorders was not affected by BVDV serostatus, except for repeat breeding (P > 0.05). The present study demonstrated that BVDV has wide distribution in the country being detected in all the 15 conurbations and 69.8% of herds involved in the study.

    Dreams preoccupied the Greek and Roman world in antiquity, therefore they had a prominent role in social, philosophical, religious, historical and political life of those times. They were considered as omens and prophetic signs of future events in private and public life, and that was particularly accentuated when elements of actions which took place in the plot of dreams were associated directly or indirectly with real events. This is why it was important to use them in divination, and helped the growth of superstition and folklore believes. Medicine as a science and an anthropocentric art, could not ignore the importance of dreams, having in mind their popularity in antiquity. In ancient Greek medicine dreams can be divided into two basic categories. In the first one -which is related to religious medicine-dreams experienced by religionists are classified, when resorted to great religious sanctuaries such as those of Asclepius (Asclepieia) and Amphiaraos (Amfiaraeia). These dreams were the essential element for healing in this form of religious medicine, because after pilgrims underwent purifications they went to sleep in a special dwelling of the sanctuaries called "enkoimeterion" (Greek: the place to sleep) so that the healing god would come to their dreams either to cure them or to suggest treatment. In ancient Greek literature there are many reports of these experiences, but if there may be phenomena of self-suggestion, or they could be characterized as propaganda messages from the priesthood of each sanctuary for advertising purposes. The other category concerns the references about dreams found in ancient Greek medical literature, where one can find the attempts of ancient Greek physicians to interpret these dreams in a rational way as sings either of a corporal disease or of psychological distress. This second category will be the object of our study. Despite the different ways followed by each ancient Greek physician in order to explain dreams, their

    A major human Q fever epidemic occurred in The Netherlands during 2007-2009. In response, all pregnant goats from infected herds were culled before the 2010 kidding season without individual testing. The aim of this study was to assess whether high risk animals from recently infected naive herds can be identified by diagnostic testing. Samples of uterine fluid, milk and vaginal mucus from 203 euthanized pregnant goats were tested by PCR or ELISA. The results suggest that testing followed by culling of only the high risk animals is not a feasible method for protecting public health, mainly due to the low specificity of the tests and variability between herds. The risk of massive bacterial shedding during abortion or parturition can only be prevented by removal of all pregnant animals from naive recently infected herds. Copyright © 2014 Elsevier Ltd.

    Coxiella burnetii may cause reproduction disorders in pregnant animals but subclinical infection in other animals. Unrecognised disease may delay implementation of control interventions, resulting in transmission of infection to other livestock and to humans. Seroreactivity to C. burnetii phase-specific antigens, is routinely used to interpret the course of human Q fever. This approach could be similarly useful in identifying new and existing infections in livestock herds to help describe risk factors or production losses associated with the infections and the implementation of disease-control interventions. This study aimed to elucidate the dynamics of C. burnetii infections using seroreactivity to phase-specific antigens and to examine the impact of infection on milk yield in goats in an endemically-infected farm that was associated with a Q fever outbreak in Australia. Seroreactivity pre- and post-partum and milk yield were studied in 164 goats (86 nulliparous and 78 parous). Post-partum, the seroprevalence of antibodies to C. burnetti increased from 4.7% to 31.4% throughout goats' first kiddings and from 47.4% to 55.1% in goats kidding for the second or greater time. Of 123 goats that were seronegative pre-partum, 26.8% seroconverted over the three-month peri-partum period, highlighting the importance of controlling infection throughout this time. The risk of seroconversion was comparable in first or later kidders, suggesting constant risk irrespective of parity. No loss in milk production associated with seroconversion to phase 2 was observed within the first nine weeks of lactation. However, seroconversion to only phase 1 was associated with extra 0.276L of milk per day (95% Confidence Interval: 0.010, 0.543; P=0.042), which warrants further investigation to ascertain whether or not the association is causal. Further studies on seroreactivity and milk production over longer periods are required, as milk production loss caused by C. burnetti may be an

    Berberine is a plant alkaloid with antimicrobial activity against a variety of microorganisms. In this study, the antimicrobial properties of berberine against multi-drug resistant field isolates of Staphylococcus epidermidis were investigated using berberine alone or in combination with a commonly used antibiotics in veterinary clinics, including penicillin, lincomycin, and amoxicillin. The results indicated that the minimum inhibitory concentrations of berberine, penicillin, lincomycin, and amoxicillin against field S. epidermidis isolates were 2-512, 0.8-213, 0.4-1024, and 0.4-256 mg/mL, respectively. Furthermore, the synergistic effects of antimicrobial activity against these multi-drug resistant isolates were observed when the berberine was combined with penicillin, lincomycin, or amoxicillin; no antagonistic effect of the combination was detected in any of the clinical isolates. These observations were further confirmed using a time-killing assay, in which a combination of 2 agents yielded a greater than 2.03-2.44 log10 decrease in colony-forming unit/mL compared with each agent alone. These findings suggest that berberine is a promising compound for preventing and treating multi-drug resistant S. epidermidis infected mastitis in dairy cows either alone or in combination with other commonly used antibiotics, such as penicillin, lincomycin, and amoxicillin.

    The exact influence of caprine arthritis encephalitis virus (CAEV) infection on blood and milk polymorphonuclear leukocytes (PMNLs) and monocyte/macrophages of goats remains unclear. Thus, the present study sought to explore the blood and milk PMNL and monocyte/macrophage functions in naturally CAEV-infected goats. The present study used 18 healthy Saanen goats that were segregated according to sera test outcomes into serologically CAEV negative (n=8; 14 halves) and positive (n=10; 14 halves) groups. All milk samples from mammary halves with milk bacteriologically positive outcomes, somatic cell count ≥2×10 6 cellsmL -1 , and abnormal secretions in the strip cup test were excluded. We evaluated the percentage of blood and milk PMNLs and monocyte/macrophages, the viability of PMNLs and monocyte/macrophages, the levels of intracellular reactive oxygen species (ROS) and the nonopsonized phagocytosis of Staphylococcus aureus and Escherichia coli by flow cytometry. In the present study, a higher percentage of milk macrophages (CD14 + ) and milk polymorphonuclear leukocytes undergoing late apoptosis or necrosis (Annexin-V + /Propidium iodide + ) was observed in CAEV-infected goats; we did not find any further alterations in blood and milk PMNL and monocyte/macrophage functions. Thus, regarding our results, the goats naturally infected with CAEV did not reveal pronounced dysfunctions in blood and milk polymorphonuclear leukocytes and monocytes/macrophages.

    Full Text Available In order to standardize language of medicine, it is essential to have a good command of ancient Greek and Latin. We cannot deny a huge impact of ancient Greek medicine on medical terminology. Compounds of Greek origin related to terms for organs, illnesses, inflammations, surgical procedures etc. have been listed as examples. They contain Greek prefixes and suffixes transcribed into Latin and they have been analyzed. It may be concluded that the modern language of medicine basically represents the ancient Greek language transcribed into Latin.

    The objective of this study was to compare the effect of 4 antiseptic compounds on the healing rate and incidence of infection of umbilical cords in newborn calves (n=60). Late gestation Jersey cows were monitored at a commercial farm (Sioux Jersey, Salix, IA) and newborn purebred (n=30) and crossbred (n=30) calves were obtained within 30min after birth. Calves were alternately assigned by birth order to 4 treatment groups: 7% tincture of iodine, 0.1% chlorine created using a novel chlorine disinfectant technology, chlorohexidine gluconate 4.0% wt/vol, and 10% trisodium citrate. Prior to dipping (within 30min of birth), diameter of the umbilical cords (as an indicator of cord drying and healing) were determined using digital calipers. In addition, as an indicator of umbilical infections, surface temperature of the umbilical stump (along with a reference point at the midpoint of the sternum) was determined using a dual-laser infrared thermometer. These measurements were all repeated at 24±1 h of age. All data were analyzed using mixed model methods. All models included fixed effects of breed (Jersey or Jersey cross), sex (bull or heifer), and treatment. Fixed effect interactions were not included in the statistical model due to the relatively small sample size. No treatment differences were noted for healing rate of umbilical cords. Initially, mean umbilical cord diameter was 22.84±3.89mm and cords healed to a mean diameter of 7.64±4.12mm at 24 h of age. No umbilical infections were noted for calves on any treatment during the course of this study. Mean surface temperature of the umbilical stump was 33.1±2.2°C at birth (1.5±1.6°C higher than the sternal reference temperature), and at 24±1 h of age the mean temperature of the umbilical stump was 33.0±4.3°C (0.5±1.8°C lower than the sternal reference temperature). These data suggest that these antiseptic compounds are equally effective for preventing infections and permitting healing of the umbilical cord

    Full Text Available The article deals with the history of contacts and cultural exchange between the Jews and the Greeks in early and late antiquity, especially relevant not only for historians and philologists, but also for those interested in Hellenistic philosophy and the origins of Christianity, having its roots into a very complex fusion of Jewish and Greek tradition. Metropolitan city of Alexandria in Ptolemaic Egypt provided a very fruitfull milieu for this kind of cultural contact just from the time the group of seventy-two translators arrived to the city to translate the Hebrew Scripture for the famous library in the time of Ptolemy II (285-247 BCE and his librarian Demetrius of Phalerum. For the genealogy of contacts between two nations that both contributed so much to the Western thought, we may, of course, go back to the history and relevant sources. The City of Jerusalem, for instance, is mentioned for the first time in the old Egyptian Tell el-Amarna correspondence (XIV. century BCE, while the Jews (though often named as the Syrians of Palestine are referred to by many Greek authors (poet Alcaius from Lesbos, Herodotus, Theophrastus, Hecataeus of Abdera, an Egyptian priest in Heliopolis Manetho, Polybius, Menander, and many others. The Hebrew Bible (Tanakh on the other hand, provides an interesting source of records of contacts between the old Israelites and the Greek speaking tribes (from the Ionian isles, Crete, Cyprus etc, back to the reign of king David and king Solomon (X. century BCE, which both allegedly enrolled Greek soldiers and officials in their armies (cf. 2 Samuel 20, 23; 1 Kings 1, 38. The Bible also reports about trade contacts between Palestine and Greek lsles (cf. Ezekiel 27, 7; Joel 4.6, and also about Greek settlers in the 'Holly land' (cf. Deuteronomy 2, 23; Jeremiah 47, 4; Zephaniah 2, 5. The period after Alexander the Great is also very important for relations between Greeks and Jews. When his diadochoi came to Palestine, they

    Fasciola hepatica and Ostertagia ostertagi infections are widespread in cattle population of Europe, however data on their prevalence in Poland are only fragmentary. Therefore, the cross-sectional study was carried out to determine the herd-level seroprevalence of F. hepatica and O. ostertagi infection in dairy cattle population in the central and north-eastern provinces Poland, and to identify basic local risk factors for these infections. In total, 598 herds were enrolled, 394 (65.9%) in the north-eastern province and 204 (34.1%) in the central province. In each herd the questionnaire survey was conducted and bulk-tank milk (BTM) sample was collected and screened using two indirect immunoenzymatic tests. Optical density ratio (ODR) was regarded as the quantitative proxy of exposure to either of the two parasites. Both Fasciola and Ostertagia ELISA ODR in the north-eastern province was significantly higher than ODR in the central province. At the cut-off value of ODR = 0.27 the true herd-level seroprevalence of F. hepatica was 79.6% (95% CI: 74.0%, 84.3%) in the north-eastern province and 13.0% (95% CI: 5.3%, 21.7%) in the central province. At the cut-off of ODR = 0.50151 of 188 herds (80.3%, 95% CI: 74.1%, 85.4%) were seropositive for O. ostertagi in the north-eastern province and only 70 of 136 herds (51.5%, 95% CI: 43.1%, 59.7%) were seropositive in the central province. Location of a herd in the north-eastern province, longer grazing period practiced in a herd and > 50%-share of grazing grass in roughage were all positively related to the increase in exposure to both parasites. Moreover, the use of hay or haylage as main roughage proved to be positively related to the increase in exposure to F. hepatica. F. hepatica and O. ostertagi are widespread in cattle population in Poland, however their occurrence at a herd-level varies between different regions of Poland. This diversity can only partly be explained by different herd management, and appears

    Lactococcus species are counted among a large and closely related group of environmental streptococci and streptococci-like bacteria that include bovine mastitis pathogenic Streptococcus, Enterococcus, and Aerococcus species. Phenotypic and biochemical identification methods can be inaccurate and unreliable for species within this group, particularly for Lactococcus spp. As a result, the incidence of Lactococcus spp. on the farm may have been historically underreported and consequently little is known about the clinical importance of this genus as a mastitis pathogen. We used molecular genetic identification methods to accurately differentiate 60 environmental streptococci and streptococci-like bacteria isolated from cows with high somatic cell count and chronic intramammary infection (IMI; >2 somatic cell scores above 4) among 5 geographically distinct farms in New York and Minnesota that exhibited an observed increase in IMI. These isolates were phenotypically identified as Streptococcus uberis and Streptococcus spp. Genetic methods identified 42 isolates (70%) as Lactococcus lactis ssp. lactis, including all 10 isolates originally phenotypically identified as Streptococcus uberis. Antibiotic inhibition testing of all Lc. lactis ssp. lactis showed that 7 isolates were resistant to tetracycline. In the present study, a predominance of Lc. lactis ssp. lactis was identified in association with chronic, clinical bovine IMI among all 5 farms and characterized antimicrobial resistance for treatment therapies. Routine use by mastitis testing labs of molecular identification methods for environmental streptococci and streptococci-like bacteria can further define the role and prevalence of Lc. lactis ssp. lactis in association with bovine IMI and may lead to more targeted therapies.

    1996-01-01

    Full Text Available The salpinx is not often treated by scholars of ancient Greek music, because it was mainly a military instrument. The instrument was usually not used for musical purposes, only for giving signals. In Greece the salpinx is known from the 8th century onwards. The Greek salpinx was an aerophone, usually made of bronze, and consisted of an 80 to 120 cm long, straight, tube with cylindrical bore, and with a conical or more often bell-shaped final, kodon, which could be made of bone. The bone had to be fired in order to get the right acoustic qualities, according to Aristotle. Salpinx is usually translated as "trumpet", but the type of sound generator it may have had has been discussed.

    Showroom10 is the first exclusive Greek designer’s showroom. It represents established and upcoming Greek designers in Greece and Cyprus. The mission and main task is to successfully place the designer’s collections in the Greek, European and worldwide market. The purpose of the showroom is to put a collection in front of the appropriate buyer accelerate its revenue growth and create brand awareness. The search for new collections is one of the most important tasks and challenge of a showroom’s business. Market research, travels and fashion trade shows are some ways to stand before an interested brand. Each collection must first be selected in terms of authenticity, clear brand DNA as we call it in fashion. Secondly, must be competitive in terms of materials, designs and prices. But, are all the above enough for the global fashion market? This paper describes a case study (Showroom 10), showing a general overview about the most important phases of “designer’s road” in Greece.

    Because of history, culture, and politics, European identity has its archetypical elements in ancient Greek culture. Ancient Greek philosophy brought Logos to fore and defined it as the crucial problem and the postulate of the human. We translate the Greek term Logos in English as reason or rationality. These terms, however, do not cover the semantic field of Logos since this includes, among other things, order of being, ground, language, argument etc. The juxtaposition of Logos (reason) to m...

    Ronald J. Erskine

    2011-01-01

    Full Text Available Thirteen bovine leukemia virus- (BLV- negative and 22 BLV-positive Holstein cows were immunized with J5 Escherichia coli bacterin at dry off, three weeks before calving, during the second week after calving, and three weeks after the third immunization. Serum was collected before the initial immunization, immediately before the third and fourth immunizations, and 21 days after the fourth immunization. Anti-J5 E. coli IgM, IgG1, and IgG2 titers were determined by ELISA. Anti-J5 E. coli IgM titers did not differ significantly (P=.98 between groups. Increases in anti-J5 E. coli IgG1 titers were higher in the BLV-negative cows (P=.057. Geometric mean anti-J5 E. coli IgG2 titers increased fourfold in the BLV-negative cows, which was significantly higher (P=.007 than the twofold increase in the BLV-positive cows. Cattle infected with BLV may have impaired serologic responses following immunization with J5 bacterin, and response may differ according to antibody isotype.

  15. Survival and detection of coliforms, Enterobacteriaceae, and gram-negative bacteria in Greek yogurt.

    2017-02-01

    Despite the widespread use of coliforms as indicator bacteria, increasing evidence suggests that the Enterobacteriaceae (EB) and total gram-negative groups more accurately reflect the hygienic status of high-temperature, short-time pasteurized milk and processing environments. If introduced into milk as postpasteurization contamination, these bacteria may grow to high levels and produce a wide range of sensory-related defects. However, limited information is available on the use and survival of bacterial hygiene indicators in dairy products outside of pasteurized fluid milk and cheese. The goal of this study was to (1) provide information on the survival of a diverse set of bacterial hygiene indicators in the low pH environment of Greek yogurt, (2) compare traditional and alternative detection methods for their ability to detect bacterial hygiene indicators in Greek yogurt, and (3) offer insight into optimal hygiene indicator groups for use in low-pH fermented dairy products. To this end, we screened 64 bacterial isolates, representing 24 dairy-relevant genera, for survival and detection in Greek yogurt using 5 testing methods. Before testing, isolates were inoculated into plain, 0% fat Greek yogurt (pH 4.35 to 4.65), followed by a 12-h hold period at 4 ± 1°C. Yogurts were subsequently tested using Coliform Petrifilm (3M, St. Paul, MN) to detect coliforms; Enterobacteriaceae Petrifilm (3M), violet red bile glucose agar and the D-Count (bioMérieux, Marcy-l'Étoile, France) to detect EB; and crystal violet tetrazolium agar (CVTA) to detect total gram-negative bacteria. Overall, the non-EB gram-negative isolates showed significantly larger log reductions 12 h after inoculation into Greek yogurt (based on bacterial numbers recovered on CVTA) compared with the coliform and noncoliform EB isolates tested. The methods evaluated varied in their ability to detect different microbial hygiene indicators in Greek yogurt. Crystal violet tetrazolium agar detected the highest

    The objective of this study was to estimate the preventive effect of various dry cow management measures against quarter new intramammary infections (IMI) during the dry period up to 21 d postcalving. Moreover, the potential publication bias was assessed in the studies selected for this analysis. The intervention measures were blanket dry cow therapy (BDCT), selective dry cow therapy (SDCT), cloxacillin compared with other dry cow therapy products, and teat sealant. A meta-analysis relative risk (RR) was calculated per intervention and pathogen group when enough studies were available from the 33 selected studies. Results of the meta-analyses were examined using publication bias tests. Blanket dry cow therapy showed significant protection against new IMI caused by Streptococcus spp. [the pooled RR was 0.39 (0.30 to 0.51)] but no protection was observed against coliform new IMI [the pooled RR was 0.95 (0.81 to 1.10)]. After correction for publication bias, it became doubtful whether DCT is protective against new Staphylococcus spp. IMI. Cloxacillin showed similar protection against new quarter IMI compared with other DCT products [the pooled RR was 1.09 (0.94 to 1.25)]. Selective dry cow therapy showed higher protection against new IMI compared with no DCT [the pooled RR was 0.51 (0.30 to 0.86)]. However, BDCT showed more protection when compared with SDCT [the pooled RR was 0.55 (0.37 to 0.80)], but the inference about whether BDCT is superior to SDCT was dependent on whether the selection criteria for SDCT was at the cow or quarter level. Internal teat sealants showed significant protection against new IMI during the dry period [the pooled RR was 0.39 (0.18 to 0.82)]. Publication bias should be taken into account when attempts are made to review literature in a meta-analysis.

    2015-08-01

    In summer 2007, a randomized controlled field trial was initiated on 6 large Midwest commercial dairy farms to investigate the effect of feeding heat-treated (HT) colostrum on transmission of Mycobacterium avium ssp. paratuberculosis (MAP) and on future milk production and longevity within the herd. On each farm, colostrum was collected daily from fresh cows, pooled, divided into 2 aliquots, and then 1 aliquot was heat-treated in a commercial batch pasteurizer at 60°C for 60min. A sample from each batch of colostrum was collected for PCR testing (MAP-positive vs. MAP-negative). Newborn heifer calves were removed from the dam within 30 to 60min of birth and systematically assigned to be fed 3.8 L of either fresh (FR; n=434) or heat-treated (HT; n=490) colostrum within 2h of birth. After reaching adulthood (>2 yr old), study animals were tested once annually for 3 yr (2010, 2011, 2012) for infection with MAP using serum ELISA and fecal culture. Lactation records describing milk production data and death or culling events were collected during the 3-yr testing period. Multivariable model logistic and linear regression was used to investigate the effect of feeding HT colostrum on risk for testing positive to MAP during the 3-yr testing period (positive/negative; logistic regression) and on first and second lactation milk yield (kg/cow; linear regression), respectively. Cox proportional hazards regression was used to investigate the effect of feeding HT colostrum on risk and time to removal from the herd. Fifteen percent of all study animals were fed PCR-positive colostrum. By the end of the 3-yr testing period, no difference was noted in the proportion of animals testing positive for MAP, with either serum ELISA or fecal culture, when comparing the HT group (10.5%) versus the FR group (8.1%). There was no effect of treatment on first- (HT=11.797kg; FR=11,671kg) or second-lactation (HT=11,013kg; FR=11,235kg) milk production. The proportion of cows leaving the herd by

    Full Text Available The trajectory of the bow in the History of Greece is associated with the transformation that was originated inside of the military environment. The poor prominence that for many centuries was granted to the archers in the warlike context, was going to give an unexpected draft with the explosion of the Persian Wars. Later, the playwright Euripides was going to turn Herakles, one of the most famous archer of the hellenic world, into the spokesman of the change that was going to bring with it the acceptance and the definitive incorporation of these soldiers as contingent of considerable value inside the greek armies.

    2015-07-01

    A cross-sectional study on clinical mastitis, intramammary infection (IMI) and blind quarters was conducted on 50 smallholder dairy farms in Jimma, Ethiopia. A questionnaire was performed, and quarters of 211 cows were sampled and bacteriologically cultured. Risk factors at the herd, cow, and quarter level for clinical mastitis and (pathogen-specific) intramammary infection were studied using multilevel modeling. As well, factors associated with quarters being blind were studied. Eleven percent of the cows and 4% of the quarters had clinical mastitis whereas 85% of the cows and 51% of the quarters were infected. Eighteen percent of the cows had one or more blind quarter(s), whereas 6% of the quarters was blind. Non-aureus staphylococci were the most frequently isolated pathogens in both clinical mastitis cases and IMI. The odds of clinical mastitis was lower in herds where heifers were purchased in the last year [odds ratio (OR) with 95% confidence interval: 0.11 (0.01-0.90)], old cows (>4 years) [OR: 0.45 (0.18-1.14)], and quarters not showing teat injury [OR: 0.23 (0.07-0.77)]. The odds of IMI caused by any pathogen was higher in herds not practicing teat drying before milking (opposed to drying teats with 1 towel per cow) [OR: 1.68 (1.05-2.69)], cows in later lactation (>180 DIM opposed to ≤90 DIM) [OR: 1.81 (1.14-2.88)], cows with a high (>3) body condition score (BCS) [OR: 1.57 (1.06-2.31)], right quarters (opposed to a left quarter position) [OR: 1.47 (1.10-1.98)], and quarters showing teat injury [OR: 2.30 (0.97-5.43)]. Quarters of cows in herds practicing bucket-fed calf feeding (opposed to suckling) had higher odds of IMI caused by Staphylococcus aureus [OR: 6.05 (1.31-27.90)]. Except for BCS, IMI caused by non-aureus staphylococci was associated with the same risk factors as IMI caused by any pathogen. No access to feed and water immediately after milking [OR: 2.41 (1.26-4.60)], higher parity [OR: 3.60 (1.20-10.82)] and tick infestation [OR: 2.42 (1

    Full Text Available Learning Greek as a second or foreign language has drawn the attention of many researchers throughout time. A dictionary is amongst the first things a foreign language student uses. Reading comprehension is significantly improved by the use of a dictionary, especially when this includes the way words are pronounced. We developed a assistance software for learning the Greek Language via Greeklish. Since, the basic vocabulary of a language is the basis of understanding the language itself, the dictionary proposed aims to make the basic Greek words easier to pronounce as well as to give the explanation of the word in English. The aim of this software is to provide a useful tool to learn the Greek language individually. Moreover, it aims to be involved, as an assistance tool for learning Greek as a second or foreign language.

    Neospora caninum is an important cause of abortion in dairy cattle. The general health of affected cows has not been investigated before. Therefore, the main objective of this study was to identify possible relationships between certain metabolic diseases and selected serum biochemical parameters in seropositive dairy cows against N. caninum antibodies in different stages of lactation. The study was carried out using 72 N. caninum seropositive cows and 61 seronegative dairy cows (control). Serum from all cows was tested to determine their N. caninum status (seropositive vs seronegative) using commercially available indirect enzyme-linked immunosorbent assay test kit (iELISA). In addition, serum biochemical parameters including beta-hydroxybutyrate (BHB), glucose, creatinine, blood urea nitrogen, total protein, albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) and gamma-glutamyltranspeptidase (GGT) were determined using routine laboratory methods. The stage of lactation was obtained at the time of sampling from farm records. Student independent t-test showed that there was a significant difference in the serum concentrations of BHB, AST, ALT, and LDH between seropositive and seronegative cows. There was no significant association between seropositivity and the stage of lactation. However, multivariable logistic regression analysis showed that there was a strong association between seropositivity and BHB concentrations. Results of this study indicate a possible relationship between N. caninum seropositivity and certain metabolic diseases such as ketosis and fatty liver syndrome in dairy cows.

    OBJECTIVE To describe use of whole-genome sequencing (WGS) and evaluate the apparent sensitivity and specificity of antemortem tuberculosis tests during investigation of an unusual outbreak of Mycobacterium bovis infection in a Michigan dairy herd. DESIGN Bovine tuberculosis (bTB) outbreak investigation. ANIMALS Cattle, cats, dog, and wildlife. PROCEDURES All cattle in the index dairy herd were screened for bTB with the caudal fold test (CFT), and cattle ≥ 6 months old were also screened with a γ-interferon (γIFN) assay. The index herd was depopulated along with all barn cats and a dog that were fed unpasteurized milk from the herd. Select isolates from M bovis-infected animals from the index herd and other bTB-affected herds underwent WGS. Wildlife around all affected premises was examined for bTB. RESULTS No evidence of bTB was found in any wildlife examined. Within the index herd, 53 of 451 (11.8%) cattle and 12 of 21 (57%) cats were confirmed to be infected with M bovis. Prevalence of M bovis-infected cattle was greatest among 4- to 7-month-old calves (16/49 [33%]) followed by adult cows (36/203 [18%]). The apparent sensitivity and specificity were 86.8% and 92.7% for the CFT and 80.4% and 96.5% for the γIFN assay when results for those tests were interpreted separately and 96.1% and 91.7% when results were interpreted in parallel. Results of WGS revealed that M bovis-infected barn cats and cattle from the index herd and 6 beef operations were infected with the same strain of M bovis. Of the 6 bTB-affected beef operations identified during the investigation, 3 were linked to the index herd only by WGS results; there was no record of movement of livestock or waste milk from the index herd to those operations. CONCLUSIONS AND CLINICAL RELEVANCE Whole-genome sequencing enhanced the epidemiological investigation and should be used in all disease investigations. Performing the CFT and γIFN assay in parallel improved the antemortem ability to detect M bovis-infected

    2012-08-01

    Full Text Available Mycobacterium avium subsp. paratuberculosis (MAP is the etiologic agent of paratuberculosis. The disease affects cows and other ruminants and causes high economic losses, mainly for dairy production. MAP may also have a role in the development of Crohn’s disease in humans. Infected animals shed viable MAP with milk and faeces and humans may assume MAP via the consumption of contaminated milk and dairy products. Current methods of milk pasteurization are not sufficient to kill all MAP cells present in milk and MAP has been found in raw or pasteurized milk and isolated from cheese. The aim of this paper is to review the current knowledge about MAP in dairy production. We analyzed studies on milk contamination, effect of pasteurization and methods for identification of MAP that can be applied to dairy products.

    The objectives of this study were (1) to record the major pathogens associated with subclinical mastitis (SCM), (2) to calculate their incidence during the milking period, and (3) to estimate the effect of SCM on daily milk yield (DMY) for goats reared under low-input management schemes. Dairy goats (n=590) of Skopelos and indigenous Greek breeds from 4 herds were randomly selected for the study. The study included monthly monitoring, milk yield recording, and bacteriological analyses of milk of individual goats during the course of 2 successive milking periods. Incidence and cumulative incidence were calculated for SCM cases. Moreover, 2 mixed linear regression models were built to assess the effects of (1) SCM and (2) different pathogens isolated from SCM cases, on DMY. The estimated incidence and cumulative incidence of SCM for the first and the second year of the study were 69.5 and 96.4 new cases of SCM/1,000 goat-months, and 24.1 and 31.7%, respectively. A total of 755 milk samples were subjected to microbiological examination, resulting in 661 positive cultures. Coagulase-negative and coagulase-positive staphylococci were isolated from 50.2 and 34.5% of the positive cultures, respectively. The incidence of infections (new infections per 1,000 goat-months) for the first and the second year of the study were 34 and 53 for coagulase-negative staphylococci, 23 and 28 for coagulase-positive staphylococci, 3 and 5 for Streptococcus/Enterococcus spp., and 5.5 and 9.1 for gram-negative bacteria. Goats with SCM had lower DMY when compared with goats without SCM (ca. 47g/d, corresponding to a 5.7% decrease in DMY). In particular, goats with SCM due to coagulase-positive staphylococci infection produced approximately 80g/d less milk (a reduction of ca. 9.7%) compared with uninfected ones, whereas SCM due to gram-negative bacteria resulted in approximately 15% reduction in DMY. Investigating the epidemiology of SCM and its effects on production traits is critical for

    The misdiagnosis of intramammary infections (IMI) with Streptococcus agalactiae (S. agalactiae) could lead farmers to treat or cull animals unnecessarily. The objective of this field study was to estimate the sensitivity (Se) and specificity (Sp) of real-time PCR at different cut-offs for cycle threshold (Ct) values against bacterial culture (BC) for diagnosis of S. agalactiae IMI using latent class analysis to avoid the assumption of a perfect reference test. A total of 614 dairy cows were randomly selected from 6 herds with bulk tank PCR Ct value ≤ 39 for S. agalactiae and S. aureus. At milk recording, 2456 quarter milk samples were taken aseptically for BC and the routinely taken cow level milk samples were analyzed by PCR. Results showed that 53 cows (8.6%) were positive for S. agalactiae IMI by BC. Sensitivity of PCR at cut-offs; ≤ 39, ≤ 37, ≤ 34, and ≤ 32, was 96.2%, 91.9%, 87.2% and 73.9%, while Se of BC was 25.7%, 29.9%, 59.9% and 72.1%. Specificity of PCR at cut-offs; ≤ 39, ≤ 37, ≤ 34, and ≤ 32, was 96.8%, 96.9%, 96.7%, and 97.22%, while Sp of BC was 99.7%, 99.5%, 99.2%, and 98.9%. The estimated prevalence of S. agalactiae IMI by PCR was higher than the apparent prevalence at the tested cut-offs, indicating under estimation of S. agalactiae IMI in the examined dairy cows. In conclusion, Se of PCR is always higher than Se of BC at all tested cut-offs. The lower cut-off, the more comparable becomes Se of PCR and Se of BC. The changes in Se in both PCR and BC at different Ct-value cut-offs may indicate a change in the definition of the latent infection. The similar Se of both tests at cut-off ≤ 32 may indicate high concentrations of S. agalactiae viable cells, representing a cow truly/heavily infected with S. agalactiae and thus easier to detect with BC. At cut-off ≤ 39 the latent definition of infection may reflect a more general condition of cows being positive for S. agalactiae. Our findings indicate that PCR Ct-value cut-offs should

    Mammary ductal morphogenesis during prepuberty occurs mainly in response to insulin-like growth factor-1 (IGF-1) and estradiol stimulation. Dairy heifers infected with gastrointestinal nematodes have reduced IGF-1 levels, accompanied by reduced growth rate, delayed puberty onset, and lower parenchyma-stroma relationship in their mammary glands. Immunohistochemical studies were undertaken to determine variations in cell division rate, IGF-1 system components, and estradiol receptors (ESR) during peripubertal development in the mammary glands of antiparasitic-treated and untreated Holstein heifers naturally infected with gastrointestinal nematodes. Mammary biopsies were taken at 20, 30, 40, and 70 wk of age. Proliferating cell nuclear antigen immunolabeling, evident in nuclei, tended to be higher in the parenchyma of the glands from treated heifers than in those from untreated. Insulin-like growth factor binding proteins (IGFBP) type 2 and type 3 immunolabeling was cytoplasmic and was evident in stroma and parenchyma. The IGFBP2-labeled area was lower in treated than in untreated heifers. In the treated group, a maximal expression of this protein was seen at 40 wk of age, whereas in the untreated group the labeling remained constant. No differences were observed for IGFBP3 between treatment groups or during development. Immunolabeling for α ESR (ESR1) was evident in parenchymal nuclei and was higher in treated than in untreated heifers. In the treated group, ESR1 peaked at 30 wk of age and then decreased. These results demonstrate that the parasite burden in young heifers negatively influence mammary gland development, affecting cell division rate and parameters related to estradiol and IGF-1 signaling in the gland.

    The risk of infection may be increased in people under stress such as shift workers. This study examined the effect of a fermented dairy product containing the probiotic Lactobacillus casei DN-114 001 (verum) on the incidence of respiratory and gastrointestinal common infectious diseases (CIDs) and on immune functions in healthy shift workers. The study was single-center, randomized, double-blind, and controlled. Volunteers received 200 g/day of verum (n = 500) or control product (n = 500) for 3 months; 1-month follow-up was carried out. The cumulated number of CIDs (primary outcome) was not significantly different between groups. Because the Poisson distribution of the primary parameter did not fully fit the observed data, a post hoc categorical analysis was applied and showed a significantly lower cumulated number of CIDs in the verum group during the product consumption phase (odds ratio [OR] = 0.75, 95% confidence interval [CI] 0.59-0.95, p = 0.017). Verum also reduced the proportion of volunteers experiencing at least 1 CID (43% vs. 51%, p = 0.005), increased the time to the first occurrence of CID (p = 0.017) in the whole population, and reduced the cumulated number of CIDs in the subgroup of smokers (p = 0.033). In the course of CID, cumulated duration of fever was lower in the verum group (in the whole study phase) (p = 0.022), and an increase in leukocyte, neutrophil, and natural killer (NK) cell counts and activity (p = 0.047 to p fermented dairy product containing Lactobacillus casei DN-114 001 could reduce the risk of common infections in stressed individuals such as shift workers.

    Full Text Available In textual criticism it is important to detect the genesis of mistakes; sometimes the true reading is only reached through the unmasking of the wrong one. Likewise, in order to use critically the Septuagint it is indispensable to find out first its corruptions and mistranslations. The making of a Greek-Hebrew Index of the Antiochene Text in the Historical Books is an excellent occasion to observe the translation process and find out the most common errors made by the translators. A few examples will be commented concerning the following issues: inner-Greek corruptions and misleading translations caused by the graphic confusion of similar letters (paleography or sounds (phonetics, and by a different reading or vocalization of the consonantal text. In several cases this analysis may open a window towards a non-Masoretic Hebrew Vorlage.

Further volumes will follow, including Mediaeval and Renaissance Logic and Logic: A History of its Central. In designing the Handbook of the History of Logic, the Editors have taken the view that the history of logic holds more than an antiquarian interest, and that a knowledge of logic's rich and sophisticated development is, in various respects, relevant to the research programmes of the present day. Ancient logic is no exception. The present volume attests to the distant origins of some of modern logic's most important features, such as can be found in the claim by the authors of t...

    The college years offer an opportunity for new experiences, personal freedom, and identity development; however, this period is also noted for the emergence of risky health behaviors that place college students at risk for health problems. Affiliation with on-campus organizations such as fraternities or sororities may increase a students' risk given the rituals and socially endorsed behaviors associated with Greek organizations. In this study, we examined alcohol and drug use, smoking, sexual behavior, eating, physical activity, and sleeping in 1,595 college students (n = 265 Greek members, n = 1,330 non-Greek members). Results show Greek members engaged in more risky health behaviors (e.g., alcohol use, cigarette smoking, sexual partners, and sex under the influence of alcohol or drugs) than non-Greek members. Greek and non-Greek members did not differ in condom use, unprotected sex, eating, and physical activity behaviors. Implications for prevention and intervention strategies among Greek members are discussed.

    In this paper, I examine the importance of class, ethnicity and gender in the causation and meaning of somatization for Greek women in Montreal. I argue that nevra--a form of psychosocial distress experienced by many of the women--is a phenomenon of the poor working conditions, low wages and gender relations in the Greek community. Data is based on interviews with 100 Greek families in Montreal and 45 patients in two different clinical settings. Comparing results with material on nervios and nerves from Latin America and the United States, I concur with Low (1985) that nerves should be viewed as a 'culturally-interpreted symptom' rather than a 'culture bound syndrome'. It is further suggested that the importance of social and material conditions and gender relations in mediating the cultural interpretation must be stressed. Failure to do so often results in the medicalization of nevra and the creation of a chronic sick role for the patient.

    Full Text Available Greek documentary papyri form an important direct source for Ancient Greek. It has been exploited surprisingly little in Greek linguistics due to a lack of good tools for searching linguistic structures. This article presents a new tool and digital platform, “Sematia”, which enables transforming the digital texts available in TEI EpiDoc XML format to a format which can be morphologically and syntactically annotated (treebanked, and where the user can add new metadata concerning the text type, writer and handwriting of each act of writing. An important aspect in this process is to take into account the original surviving writing vs. the standardization of language and supplements made by the editors. This is performed by creating two different layers of the same text. The platform is in its early development phase. Ongoing and future developments, such as tagging linguistic variation phenomena as well as queries performed within Sematia, are discussed at the end of the article.

The epsilon4 allele is associated with increased plasma cholesterol, atherosclerosis and cardiovascular disease, Alzheimer's disease, and decreased longevity. The objective of the present study was to estimate the distribution of APOE alleles in the Greek population by DNA analysis. The material consisted of 216 voluntary, healthy Greek blood donors (146 males/70 females). The APOE allele frequencies were epsilon2: 5.3%, epsilon3: 88.2%, epsilon4: 6.5%. The epsilon4 allele frequency of 6.5% in the Greek population is, together with the frequency in the Chinese population, among the lowest in the world.

    Danish farmers can order a real-time PCR mastitis diagnostic test on routinely taken cow-level samples from milk recordings. Validation of its performance in comparison to conventional mastitis diagnostics under field conditions is essential for efficient control of intramammary infections (IMI) with Staphylococcus aureus (S. aureus). Therefore, the objective of this study was to estimate the sensitivity (Se) and specificity (Sp) of real-time PCR, bacterial culture (BC) and California mastitis test (CMT) for the diagnosis of the naturally occurring IMI with S. aureus in routinely collected milk samples using latent class analysis (LCA) to avoid the assumption of a perfect reference test. Using systematic random sampling, a total of 609 lactating dairy cows were selected from 6 dairy herds with bulk tank milk PCR cycle threshold (Ct) value ≤39 for S. aureus. At routine milk recordings, automatically obtained cow-level (composite) milk samples were analyzed by PCR and at the same milking, 2436 quarter milk samples were collected aseptically for BC and CMT. Results showed that 140 cows (23%) were positive for S. aureus IMI by BC while 170 cows (28%) were positive by PCR. Estimates of Se and Sp for PCR were higher than test estimates of BC and CMT. SeCMT was higher than SeBC however, SpBC was higher than SpCMT. SePCR was 91%, while SeBC was 53%, and SeCMT was 61%. SpPCR was 99%, while SpBC was 89%, and SpCMT was 65%. In conclusion, PCR has a higher performance than the conventional diagnostic tests (BC and CMT) suggesting its usefulness as a routine test for accurate diagnosis of S. aureus IMI from dairy cows at routine milk recordings. The use of LCA provided estimates of the test characteristics for two currently diagnostic tests (BC, CMT) and a novel technique (real-time PCR) for diagnosing S. aureus IMI under field conditions at routine milk recordings in Denmark.

    2017-03-01

    Full Text Available Methicillin-resistant Staphylococcus aureus (MRSA is classified as hospital associated (HA, community associated (CA, livestock associated (LA and is a global concern. Developing countries, like India, are densely populated country challenging for public hygiene practices. HA-MRSA is comfortably recorded in India, and CA-MRSA is also reported as increasing one. CA-MRSA is serious disease which affects the community as endemic. MRSA is one among major mastitis-causing organisms in India as LA-MRSA. There were reports for transmission of MRSA as community between milk handlers and cow in global perspective. In India reports of MRSA in short among milk handlers and also transmission between animal and human. Hence, proper monitoring of MRSA transmission in India should be elucidated in account among milk handlers and dairy cows to avoid emerging CA-MRSA as outbreak.

    The aim of the present work was to examine a dairy herd with an anamnesis of recurrent clinical mastitis and decreased milk production. A total of 239 individual cow milk samples originating from asymptomatic cows were collected at four-month intervals and examined mainly for the presence of Staphylococcus aureus and mastitis streptococci using standard cultivation methods. In total, 29.7% and 9.2% samples were positive for S. aureus and mastitis streptococci, respectively. Unlike for mastitis streptococci, the prevalence of animals positive for S. aureus had an increasing trend (pmastitis, reproductive and periparturient disorders and administration of antibiotics. In contrast to S. aureus, the occurrence of mastitis streptococci in milk was linked with previous cases of clinical mastitis and intramammary administration of antibiotics.

    Current diagnostic tests for Johne's disease (JD), a chronic granulomatous inflammation of the gastrointestinal tract of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP), lack the sensitivity to identify infected animals at early (asymptomatic) stages of the disease. The objective was to determine the pattern of MAP-associated dysbiosis of intestinal microbiota as a potential biomarker for early detection of infected cattle. To that end, genomic DNA was extracted from ileal mucosa and fecal samples collected from 28 MAP-positive and five control calves. High-throughput Illumina sequencing of the V4 hypervariable region of the 16S rRNA gene was used for community profiling of ileal mucosa-associated (MAM) or fecal microbiota. The PERMANOVA analysis of unweighted UniFrac distances revealed distinct clustering of ileal MAM (P = 0.049) and fecal microbiota (P = 0.068) in MAP-infected vs. control cattle. Microbiota profile of MAP-infected animals was further investigated by linear discriminant analysis effective size (LEfSe); several bacterial taxa within the phylum Proteobacteria were overrepresented in ileal MAM of control calves. Moreover, based on reconstructed metagenomes (PICRUSt) of ileal MAM, functional pathways associated with MAP infection were inferred. Enrichment of lysine and histidine metabolism pathways, and underrepresentation of glutathione metabolism and leucine and isoleucine degradation pathways in MAP-infected calves suggested potential contributions of ileal MAM in development of intestinal inflammation. Finally, simultaneous overrepresentation of families Planococcaceae and Paraprevotellaceae, as well as underrepresentation of genera Faecalibacterium and Akkermansia in the fecal microbiota of infected cattle, served as potential biomarker for identifying infected cattle during subclinical stages of JD. Collectively, based on compositional and functional shifts in intestinal microbiota of infected cattle, we inferred that

  9. The Greek Financial Crisis – Theoretical Implications

    Directory of Open Access Journals (Sweden)

    Garry Jacobs

    2015-10-01

    Full Text Available The world we live in is a product of the way we think. Our conception of reality determines what we see and what we achieve. The Greek crisis is not simply a case of high public debt, economic mismanagement or weak political will in Greece or the Eurozone. It is underpinned by economic premises, constructs and resulting practices that promote exactly the type of dilemma Greece faces today. Without addressing these conceptual issues, no lasting solution is possible. Rather it can be expected to repeat and spread to other countries and regions. This article is based on views presented by participants in a WAAS webinar examining the Greek financial crisis in the light of economic theory and practice. Wherever there are unmet social needs and underutilized social resources, such as high levels of unemployment, the potential exists to stimulate economic activity, enhance human welfare and promote resilience and sustainable entrepreneurship. Both conditions prevail in Greece today, but neither current nor anticipated policies are likely to result in near term benefits to the Greek people and the local economy nor for Europe and the world economy. It supports the view that a permanent and effective win-win solution can be found to the Greek crisis, compatible with the financial stability of the country and the welfare of its citizens within the framework of the Eurozone, but that such a solution will require a rethinking of fundamental theoretical issues and adoption of innovative policy instruments beyond those presently being contemplated.

    Following the European Council Directive 90/641/EURATOM of the 4 December 1990, on the operational protection of outside workers exposed to the risk of ionising radiation during their activities in controlled areas, the Greek Government has adopted the Ministerial Order, published in the Official Gazette (No 9087(FOR) 1004 of 1996). The Greek Atomic Energy Commission (GAEC) is the competent governmental authority for radiation protection matters. Therefore it is the GAEC's responsibility of monitoring the implementation of this Order. The Order consists of 6 parts, where among others are described the obligations of outside undertakings and operators and the obligations of outside workers. One of the major elements of this Ministerial Order is the radiation passbook.The Greek Radiation Passbook is written in two languages, Greek and English. It contains worker's personal data (identity, medical examinations, training in radiation protection, etc), information concerning his employee (name, address, etc) and worker's dosimetry information such as operational and the official dosimetry (external and internal) data. The radiation passbook is provided only to category A outside workers, working in Greece or abroad. The GAEC distributed the Ministerial Order with application forms to the possible outside undertakings for their information. Until August 1997, 41 radiation passbooks have been attributed to outride workers. All of them are technicians dealing with medical equipment using ionizing radiation. (author)

  15. Truth Obviousness in Ancient Greek Philosophy

    Directory of Open Access Journals (Sweden)

    Halyna I. Budz

    2013-01-01

    Full Text Available The article examines the features of the axiomatic approach to the truth understanding in ancient Greek philosophy. Truth in the works by ancient philosophers has axiomatic essence, basing on divine origin of truth. As the truth has a divine origin, it is in reality. The reality, created by Gods is the solemn reality. Therefore, understanding of reality by man is the display of divine reality, which is true and clever. In of the context of ancient Greek philosophy, to know truth is to know something, existing in reality, in other words, something, truly existing, eternal reality. Consequently, to know truth is it to know the substantial reality base. That’s why the justification of the reality origin is the axiomatic doctrine of truth at the same time, because only fundamental principle “truly” exists and is the truth itself. The idea of fundamental principle in ancient Greek philosophy is the axiom, universal principle, which is the base of reality as a substance from ontological perspective and is realized as the truth from gnosiological perspective. Fundamental principle, as Greeks understand it, coincides with the truth, in other words, reality and thinking are identical. The idea of reality source is the universal criterion of world perception at the same time, in other words, it is the truth, which is perceived axiomatically.

  17. The Greek media and the Kosovo crisis

    Directory of Open Access Journals (Sweden)

    Full Text Available The NATO air attacks (24/3/99-10/6/99 as an instrument of force against Serbia to terminate the abuse of the Albanian population in Kosovo, albeit supported by a significant part of the international community, were received much differently in Greece. Key to the climate of strong disagreement with the campaign was the role of the Greek media. The true reason behind the offensive was, according to them, the change in the geopolitical map to the advantage of the West, and in particular the USA. The underlying argument of this paper is that in the Kosovo crisis the media, Greek (and international, projected their own environment. It is particularly apt to examine the Greek case because of its very unique perspective that differentiated the coverage in Greece - a NATO member country - from the overall world media view. Also, the discussion is pertinent because Greek media coverage disagreed with the official government position, which although advocating a diplomatic resolution of the crisis, had to support the Alliance's decision to bomb Serbia. Furthermore, study of this case is significant because the clash of the Greek media view with the mainstream pro-NATO coverage found in many other countries generated negative views on Greece and its media on the international level. An examination of media content reveals that despite any differences concerning political or other factors, and regardless of the variations in the phrasing of the anti-NATO arguments, the overall media perspective exhibited a unanimous opposition to the bombing campaign. By placing the emphasis more or less on the same thematic areas as the world media, but by crucially reversing the line of reasoning (e.g. the refugee problem was blamed on the NATO bombing raids and not on Serbian atrocities, the Greek media invariably remained anti-war, anti-NATO and anti-Albanian in many particular cases, and in principle pro-Serb throughout.

    Parasitic nematodes are one of the most important causes of production losses in most cattle-producing countries of the world. The aim of the present study is to make a through estimate of helminth and protozoan infection prevalence in dairy cattle around Taiwan. Coprological techniques, including direct fecal smear, simple flotation, and simple sedimentation, were used to detect gastrointestinal helminths and protozoan in dairy cattle. A total of 1259 rectal fecal samples were collected from Holstein dairy cattle at 94 farms in 13 counties in Taiwan. The overall prevalence of gastrointestinal parasitic infection was 86.9%. The infection rates of protozoa, nematodes, trematodes, and cestodes were 81.3%, 7.9%, 1.6%, and 0.6%, respectively. Among all parasites, Buxtonella sulcata (61.7%) was the most predominant one, followed with Cryptosporidium spp. (32.6%) and Eimeria spp. (11.8%). There were significant differences in the prevalence of protozoa and nematodes between different age groups and distributional area groups. The present study demonstrated that gastrointestinal parasitic infections occur frequently in dairy cattle around Taiwan, especially protozoan infections. The results indicated that a superior management system and regular anthelmintic treatment should be used for the control of parasitic infections in dairy cattle farms. Copyright © 2012.

    Previous observational studies suggest an association between polymorphism c.980A>G in the CXCR1 gene, encoding the chemokine (C-X-C motif) receptor 1, and the innate immunity and infection status of the mammary gland. Mammary glands of eight Holstein heifers were experimentally infected with a Staphylococcus chromogenes isolate originating from a chronic intramammary infection (IMI) to study differences between CXCR1 genotypes c.980AG and c.980GG. Quarters from heifers with genotypes c.980AG and c.980GG developed subclinical mastitis but showed differences in the early response at 6-18 h post challenge. Bacterial count at 18 h post challenge tended to be higher in quarters from c.980AG heifers compared to c.980GG heifers. Somatic cell count (SCC) was higher at 6 h post challenge and tended to be higher at 9 h post challenge in c.980AG heifers compared to c.980GG heifers. Milk production decreased similarly. Milk neutrophils of c.980AG heifers showed more apoptosis at 9 h post challenge and tended to show more necrosis at 6, 9 and 12 h post challenge than c.980GG heifers. Differences were less pronounced in the later stage (>18 h) of infection. The results demonstrate that CXCR1 polymorphism can influence SCC and milk neutrophil viability following experimental IMI.

  3. The Greek Concept of the State

    2010-12-01

    Full Text Available The starting-point of my paper is the general recognition of the importance of Ancient Greek democracy and Greek political philosophy for modern democracy and for the assessment of political activity today. Here I draw on the studies by Castoriadis and Hansen. With regard to the ancient definitions of the state, Aristotle’s distinctive feature is that he takes into account the topographical and political-administrative aspects, while Plato’s definitions are – predictably –characterised by the notion that a politician is one who administers state affairs on the basis of his knowledge. The discussion of the entry polis in theEtymologicum Magnum is accompanied by a brief survey of the more recent etymological explanations from the perspective of semantics. Language issues are further addressed in the section on synonyms for the polis, such as ἀκρόπολις, ἄστυ, χώρα, ἄνθρωποι, δῆμος, κοινωνία, πατρίς, ἔθνος. Describing the basic characteristics of the concept of the state, the paper begins with the territory or space, which is often merely touched upon in political theory as the latter prefers to concentrate on the functioning of the political system. According to Aristotle, the territory or space is, like the climate, an external condition of the state, but at the same time a basic one, determined by Nature, φύσις, herself. The discussion of the populace from a political perspective dwells on the Greek vocabulary referring to citizens, male and female. Among the characteristics of the Greek concept of the state, particular emphasis is placed on the religious and mythological foundation of its politics, which is evident in the worship of gods/goddesses as the tutelary deities of cities (such as Zeus, Athena, Hera, Apollo, etc., with their temples, in the cult of the hearth goddess Hestia, and in the Tholos as the Prytaneum building. A further essential quality of the ancient Greek

    Dairy proteins are amenable to structural modifications induced by high temperature, shear, and moisture; in particular, whey proteins can change conformation to new unfolded states. The change in protein state is a basis for creating new foods. The dairy products, nonfat dried milk (NDM), whey protein concentrate (WPC), and whey protein isolate (WPI) were modified using a twin-screw extruder at melt temperatures of 50, 75, and 100 degrees C, and moistures ranging from 20 to 70 wt%. Viscoelasticity and solubility measurements showed that extrusion temperature was a more significant (P extruded dairy protein ranged from rigid (2500 N) to soft (2.7 N). Extruding at or above 75 degrees C resulted in increased peak force for WPC (138 to 2500 N) and WPI (2.7 to 147.1 N). NDM was marginally texturized; the presence of lactose interfered with its texturization. WPI products extruded at 50 degrees C were not texturized; their solubility values ranged from 71.8% to 92.6%. A wide possibility exists for creating new foods with texturized dairy proteins due to the extensive range of states achievable. Dairy proteins can be used to boost the protein content in puffed snacks made from corn meal, but unmodified, they bind water and form doughy pastes with starch. To minimize the water binding property of dairy proteins, WPI, or WPC, or NDM were modified by extrusion processing. Extrusion temperature conditions were adjusted to 50, 75, or 100 degrees C, sufficient to change the structure of the dairy proteins, but not destroy them. Extrusion modified the structures of these dairy proteins for ease of use in starchy foods to boost nutrient levels.

    Full Text Available Travel writing has been viewed as one of the main sources of national typologies and is often held responsible for the consolidation of stereotypes about otherness and for the promotion of an imperialist agenda. This paper aims to investigate conceptions of Greekness in contemporary Greek travelogues which involve a rethinking of stereotypical national representations. The analysis proceeds by proposing the method of “questioning home” in travelogues through diffracted gazes towards the traveller’s homeland as a result of his encounter with otherness. In the second part, Greekness is explored beyond the nation-state approach and the long-held national stereotype of the “Greek particularism”, Greece’s isolation because of the country’s unresolved tension between East and West. A. Vistonitis’ and M. Kassolas’s travelogues reporting their travels to the East (China and to the West (USA respectively at the end of the 20th century are examined as case-studies. Through narrators’ dialogues with their hosts and the raising of relevant political and geopolitical issues, “transnational” conceptions of Greek identity are explored: the notions of “diaspora”, “cosmopolitan citizenship”, “openness” and “connectivity” challenge the national narration based on “purity” and “exclusion”, and facilitate the investigation of potential roles for Greece in the globalized world of the early 21st century.

  6. The Table of Chords and Greek Trigonometry

    Directory of Open Access Journals (Sweden)

    Stefano Buscherini

    2010-12-01

    Full Text Available Trigonometry was born due to the need of ancient astronomy to calculate and to predict the movement of the heavenly bodies. However it is hard to know who the founder of this mathematical branch was: it is likely that its origins date back to Hipparchus of Nicaea who compiled the first table of chords, which are the forerunners of the modern trigonometric function “sine”. Nevertheless the most ancient existing work on trigonometry is the Almagest of Ptolemy in which the author describes the mathematical steps that are necessary for the compilation of the table of chords. These steps are based on more ancient theories and for this reason one gets the impression that they could be the result of a preparatory study. This article is not only a brief survey of Greek trigonometry but it also analyzes the Greek numeration system, the sexagesimal fractions and the arithmetical operations which were used in the calculation of the chords.

It is possible, however not obligatory, that it was not solely a fantasy but also reflected a contemporary medical practice.

    2017-12-01

    In the recent Greek ages the most devastating epidemics were plague, smallpox, leprosy and cholera. In 1816 plague struck the Ionian and Aegean Islands, mainland Greece, Constantinople and Smyrna. The Venetians ruling the Ionian Islands effectively combated plague in contrast to the Ottomans ruling all other regions. In 1922, plague appeared in Patras refugees who were expelled by the Turks from Smyrna and Asia Minor. Inoculation against smallpox was first performed in Thessaly by the Greek women, and the Greek doctors Emmanouel Timonis (1713, Oxford) and Jakovos Pylarinos (1715, Venice) made relevant scientific publications. The first leper colony opened in Chios Island. In Crete, Spinalonga was transformed into a leper island, which following the Independence War against Turkish occupation and the unification of Crete with Greece in 1913, was classified as an International Leper Hospital. Cholera struck Greece in 1853-1854 brought by the French troops during the Crimean War, and again during the Balkan Wars (1912-13) when the Bulgarian troops brought cholera to northern Greece. Due to successive wars, medical assistance was not always available, so desperate people turned many times to religion through processions in honor of local saints, for their salvation in epidemics.

    2008-01-01

    The purpose of the paper is to examine how Greek historians account for the presence of modern scientific ideas in the intellectual environment of eighteenth-century Greek-speaking society. It will also discuss the function of the history of modern Greek science in the context of Greek national historiography. As will be shown, the history of modem Greek science spent most of its life under the shadow of the history of ideas. Despite its seemingly secondary role, however, it occupied a distinctive place within national historiography because it formed the ground upon which different perceptions of the country's European identity converged. In this respect, one of the main goals of this paper is to outline the particular ideological presumptions, which shaped the historiography of modern Greek science under different historical circumstances. At the end an attempt will be made to articulate a viewpoint more in tandem with the recent methodological developments in the history of science.

    2008-09-16

    Stem-cell biologists and those involved in regenerative medicine are fascinated by the story of Prometheus, the Greek god whose immortal liver was feasted on day after day by Zeus' eagle. This myth invariably provokes the question: Did the ancient Greeks know about the liver's amazing capacity for self-repair? The authors address this question by exploring the origins of Greek myth and medicine, adopting a 2-fold strategy. First, the authors consider what opportunities the ancient Greeks had to learn about the liver's structure and function. This involves a discussion of early battlefield surgery, the beginnings of anatomical research, and the ancient art of liver augury. In addition, the authors consider how the Greeks understood Prometheus' immortal liver. Not only do the authors examine the general theme of regeneration in Greek mythology, they survey several scholarly interpretations of Prometheus' torture.

A total of 150 Holstein cows (average production of 9,000 kg of milk per lactation, with four functional udder quarters without clinical mastitis was included in the study. All animals were dried-off 60 days before the expected calving date. Two teats positioned diagonal-contralaterally received only dry cow antibiotic, control group C (n=300 and the other two teats, treatment group T (n=300 received dry cow antibiotic and infusion with an internal teat seal. Data from SCC variable were transformed by log base-10 transformation. Duncan’s test was used accepting 5% as the level of statistical significance. The occurrence of intramammary infection (IMI and chronicity rate, and frequency of microorganisms isolated at drying and immediately postpartum in teats of group C and group T were evaluated using a non-parametric Chi-square Test, accepting 10% as the statistical significance level. There was a decrease in the occurrence of new infections in the early postpartum in cows which the sealant was used (C=19.6%, T=11.4%. In the postpartum period, Gram-negative bacteria were isolated from 16 teats in C and seven in T. The greatest reduction was observed for Escherichia coli (8 vs 1 in group T. There was no effect using the internal sealant on the frequency of isolation of environmental Streptococus. The use of sealant reduced the prevalence of subclinical mastitis cows between drying-off and the early postpartum period (C=51% versus T=42% and resulted in a lower somatic cell count (SCC in the treatment group when compared with the control group (T=1,073x103, C=1,793x103.

    The aim of this case-control study was to compare Mediterranean diet (MD) adherence and anthropometry between Greek diaspora adolescents living in Istanbul and Greek adolescents, inhabitants of Athens. A total of 206 adolescents (103 from each site), aged 10.0-19.0 years old, all of Greek origin, were recruited from schools in Athens and minority schools in Istanbul, for the present case-control study. Participants at each site were age and sex-matched. Anthropometric measurements were performed, and diet adherence was assessed with the KIDMED score. Breakfast skipping, decreased dairy and increased commercially baked good/pastries consumption for breakfast, fast-food intake and consumption of several sweets each day was more prevalent in Istanbul, but, on the other hand, students from Athens reported eating fewer fruit, vegetables and nuts. The adoption of unhealthy eating habits in each site was counterbalanced by a more 'healthy' dietary element, resulting in an overall similar MD adherence between both sites. Additionally, although weight status was indifferent between the two cities, higher rates of abdominal obesity were recorded in Istanbul, when the weight-to-height ratio was used for diagnosis. Differences in several domains of the KIDMED score were recorded among cities, possibly as results of food availability and prices. However, MD adherence and weight status appeared similar, indicating that the dietary transition and acculturation experienced by the remnants is actually very slow and minimal during the 93 years since population exchange.

    A controlled study was conducted in Sydney to assess the reported characteristics of Jewish and Greek parents. Using a measure of fundamental parental characteristics the 81 Jewish subjects differed from controls only in scoring their mothers as less caring. The 125 Greek subjects scored both parents as more overprotective; further investigation revealed that the Greek parents were overprotective of their daughters only. Findings in the latter study suggest that overprotection by Greek parents may be influenced slightly by the age of the child when migrating, and that such a cultural pattern is resistant to acculturation effects.

    2015-08-01

    Most of the terminology in medicine originates from Greek or Latin, revealing the impact of the ancient Greeks on modern medicine. However, the literature on the etymology of Greek words used routinely in medical practice is sparse. We provide a short guide to the etymology and meaning of Greek words currently used in the field of hepatopancreatobiliary (HPB) anatomy and surgery. Focusing on HPB medical literature, the etymology and origin of Greek words including suffixes and prefixes are shown and analyzed. For example, anatomy (anatomia) is a Greek word derived from the prefix ana- (on, upon) and the suffix -tomy from the verb temno meaning to cut. Surgery, however, is not a Greek word. The corresponding Greek word is chirourgiki derived from cheir (hand) and ergon (action, work) meaning the action made by hands. Understanding the root of Greek terminology leads to an accurate, precise and comprehensive scientific medical language, reflecting the need for a universal medical language as a standardized means of communication within the health care sector.

    Mastitis is the most prevalent disease in dairy sheep with major economic, hygienic and welfare implications. The disease persists in all dairy sheep production systems despite the implementation of improved management practises. Selective breeding for enhanced mastitis resistance may provide the means to further control the disease. In the present study, we investigated the genetic architecture of four mastitis traits in dairy sheep. Individual animal records for clinical mastitis occurrence and three mastitis indicator traits (milk somatic cell count, total viable bacterial count in milk and the California mastitis test) were collected monthly throughout lactation for 609 ewes of the Greek Chios breed. All animals were genotyped with a custom-made 960-single nucleotide polymorphism (SNP) DNA array based on markers located in quantitative trait loci (QTL) regions for mastitis resistance previously detected in three other distinct dairy sheep populations. Heritable variation and strong positive genetic correlations were estimated for clinical mastitis occurrence and the three mastitis indicator traits. SNP markers significantly associated with these mastitis traits were confirmed on chromosomes 2, 3, 5, 16 and 19. We identified pathways, molecular interaction networks and functional gene clusters for mastitis resistance. Candidate genes within the detected regions were identified based upon analysis of an ovine transcriptional atlas and transcriptome data derived from milk somatic cells. Relevant candidate genes implicated in innate immunity included SOCS2, CTLA4, C6, C7, C9, PTGER4, DAB2, CARD6, OSMR, PLXNC1, IDH1, ICOS, FYB, and LYFR. The results confirmed the presence of animal genetic variability in mastitis resistance and identified genomic regions associated with specific mastitis traits in the Chios sheep. The conserved genetic architecture of mastitis resistance between distinct dairy sheep breeds suggests that across-breed selection programmes would be

    Full Text Available After Ottoman colonial rule, education in Greece became an important institution for the ideological construction of a Greek national identity. This paper looks at schooling in Greece just prior to the Greek Revolution and immediately after Greek Independence, and how the Greek national school system assisted in the construction of a Greek national identity. This paper is divided into several sections. The introductory section discusses how a newly independent Greek nation-state struggled to unite the Greek people under a collective national identity. While most people at the time identified with their families, communities, and Greek Orthodox Christian religion, after Greek independence people began to see themselves as members of a broader Greek nation. The section that follows provides a discussion of Greek education during Ottoman colonial rule, and how a type of Greek identity (centered around the Greek Orthodox Christian faith was maintained through the Greek Orthodox mileu. The Greek Church ran schools, and taught Greek children how to read and write, as well as the virtues of the Orthodox Christian faith. Section three of the article looks at Greek education during the early years of the Greek nation-state. In this section the general contours of the Greek educational system are delineated. The section also discusses how the organization of the Greek national school system was borrowed from extant school models found in Western Europe. Section four describes the Greek national curriculum and how the national curriculum would help to teach future generations of Greek citizens what it meant to be Greek. This is further reinforced in the Greek school textbook, which is part of the discussion in section five. Section five concludes with the role of education and its implications in uniting nations from around the world.

    Dairy small ruminants account for approximately 21% of all sheep and goats in the world, produce around 3.5% of the world's milk, and are mainly located in subtropical-temperate areas of Asia, Europe, and Africa. Dairy sheep are concentrated around the Mediterranean and Black Sea regions, where their dairy products are typical ingredients of the human diet. Dairy goats are concentrated in low-income, food-deficit countries of the Indian subcontinent, where their products are a key food source, but are also present in high-income, technologically developed countries. This review evaluates the status of the dairy sheep and goat sectors in the world, with special focus on the commercially and technically developed industries in France, Greece, Italy, and Spain (FGIS). Dairy small ruminants account for a minor part of the total agricultural output in France, Italy, and Spain (0.9 to 1.8%) and a larger part in Greece (8.8%). In FGIS, the dairy sheep industry is based on local breeds and crossbreeds raised under semi-intensive and intensive systems and is concentrated in a few regions in these countries. Average flock size varies from small to medium (140 to 333 ewes/farm), and milk yield from low to medium (85 to 216 L/ewe), showing substantial room for improvement. Most sheep milk is sold to industries and processed into traditional cheese types, many of which are Protected Denomination of Origin (PDO) cheeses for gourmet and export markets (e.g., Pecorino, Manchego, and Roquefort). By comparing break-even milk price among FGIS countries, we observed the following: (1) most Greek and French dairy sheep farms were unprofitable, with the exception of the intensive Chios farms of Greece; (2) milk price was aligned with cost of production in Italy; and (3) profitable farms coexisted with unprofitable farms in Spain. In FGIS, dairy goat production is based on local breeds raised under more extensive systems than sheep. Compared with sheep, average dairy goat herds are

    Stavrakaki, Stavroula; Kouvava, Sofia

    2003-07-01

    The aim of this study is twofold. First, to investigate the use of functional categories by two Greek agrammatic aphasics. Second, to discuss the implications of our findings for the characterization of the deficit in agrammatism. The functional categories under investigation were the following: definite and indefinite articles, personal pronouns, aspect, tense, subject-verb agreement, wh-pronouns, complementizers and the mood marker na (=to). Based on data collected through different methods, it is argued that the deficit in agrammatism cannot be described in terms of a structural account but rather by means of difficulties in the implementation of grammatical knowledge.

    2007-06-01

    The purpose of this study was to assess Greek primary (1st to 6th grade) school children's dietary habits and the factors influencing them. Our results show that children know the value of different foods. The socio-economic status of father has no effect on the attitude of children towards choosing their diet, however, mothers' educational status appears to have an effect on their children's behaviour. Place of residence (urban or semi-rural areas) and gender does not influence their knowledge about different diets. It was, finally, shown that as children grow older they tend to eat less healthy foods.

  14. [Gods, women and pharmacy in Greek Mythology].

    Vons, J

    2001-01-01

    The study of Greek Mythology fully justifies Herophilus's phrase: "Medicines are the hands of Gods" (third cent. B.C.). A number of Gods are said to be the inventors of the drugs which are useful to men. Their names are still alive in the scholarly or popular appellations of a great many medicinal herbs. However, insofar as the action of a drug (of a Pharmakon) remains mysterious, one finds it in essentially female practices as well as in medicine. The study of these ancient beliefs, which have survived in spite of the progress of twentieth century science, can develop the history of epistemology of pharmacy by stimulating interdisciplinary research.

    Homosexuality and pedophilia in ancient Greece greatly concerned many researchers who were mainly interested in highlighting the social aspect of this phenomenon in ancient Greek society. An important source on the subject was the paintings of a man and his lover in attic black and red figured pottery, up to the end of the 5th century BC. Another main source was the information that derived from the texts of ancient Greek literature, especially poetry. Homosexuality was not only referring to relationships between males, but it was also manifested in lesbian love. It is believed that in the Homeric world homosexuality was not favored. In Greek society of the archaic period, the restriction of women at home, the satisfaction of sexual needs with courtesans, the marriage for the purpose of maintaining and managing the property, put women aside, marginalizing them in terms of social life, impeding the cultivation of emotional relationships between sexes. At the same time, in the society of those times, the aristocratic ideal, the constant communication of men during military training and the war, the male nudity in sports and the promotion of beauty and bravery in athletic contests, as well as the gatherings and the entertainment of men at the symposia, created a suitable substrate in which male homosexuality could develop. In this context, pedophile relationships were developed mainly during the archaic period, as recorded on vase paintings, where a mature man developed a special relationship with a teenager of the same social class. The mature man had the role of mentor for the juvenile, he would look after him and cover his living expenses and education cost. In this relationship, exhibiting predominantly the social dimension of an initiation process and introduction to adult life, the erotic homosexual intercourse could find a place to flourish. The above-mentioned relationship could not last forever, given that this would later transform into an emotional

    The authors report on new chemical and lead isotopic results and interpretations of archaic Greek silver coins from the Asyut hoard which was buried around 475 B.C. Aeginetan coins were of central interest in this study. Possible ancient silver mines were explored in the Aegean region in the course of several geologic expeditions, and chemically and isotopically investigated. Some of the silver sources in Greece were traced by combination of the analytical methods and questions of provenance were solved. In addition, processes of silver smelting and refining were studied. Results and implications of this work are summarized in the final section on Conclusions. (orig.) [de

    Islamic scholars of the Middle Ages are often credited with preserving the scientific writings of Antiquity through the Dark Ages of Europe. Saliba argues that the medieval Islamic astronomers did far more—actually correcting and improving on Greek astronomy by creating new mathematical tools to explain the motions of celestial objects. These tools were so useful that Copernicus appears to have borrowed them for use in his heliocentric cosmology. In this new light, the medieval Islamic astronomers played a fundamental role in the scientific revolution that was forged in Europe during the Renaissance.

    2014-12-01

    We reviewed Greek mythology to accumulate tales of resuscitation and we explored whether these tales could be viewed as indirect evidence that ancient Greeks considered resuscitation strategies similar to those currently used. Three compendia of Greek mythology: The Routledge Handbook of Greek Mythology, The Greek Myths by Robert Graves, and Greek Mythology by Ioannis Kakridis were used to find potentially relevant narratives. Thirteen myths that may suggest resuscitation (including 1 case of autoresuscitation) were identified. Methods to attempt mythological resuscitation included use of hands (which may correlate with basic life support procedures), a kiss on the mouth (similar to mouth-to-mouth resuscitation), application of burning torches (which might recall contemporary use of external defibrillators), and administration of drugs (a possible analogy to advanced life support procedures). A careful assessment of relevant myths demonstrated that interpretations other than medical might be more credible. Although several narratives of Greek mythology might suggest modern resuscitation techniques, they do not clearly indicate that ancient Greeks presaged scientific methods of resuscitation. Nevertheless, these elegant tales reflect humankind's optimism that a dying human might be restored to life if the appropriate procedures were implemented. Without this optimism, scientific improvement in the field of resuscitation might not have been achieved.

    During June and July of 2009, sudden deaths, tremulous movements and population declines of adult honey bees were reported by the beekeepers in the region of Peloponnesus (Mt. Mainalo), Greece. A preliminary study was carried out to investigate these unexplained phenomena in this region. In total, 37 bee samples, two brood frames containing honey bee brood of various ages, eight sugar samples and four sugar patties were collected from the affected colonies. The samples were tested for a range of pests, pathogens and pesticides. Symptomatic adult honey bees tested positive for Varroa destructor, Nosema ceranae, Chronic bee paralysis virus (CBPV), Acute paralysis virus (ABPV), Deformed wing virus (DWV), Sacbrood virus (SBV) and Black queen cell virus (BQCV), but negative for Acarapis woodi. American Foulbrood was absent from the brood samples. Chemical analysis revealed that amitraz, thiametoxan, clothianidin and acetamiprid were all absent from symptomatic adult bees, sugar and sugar patty samples. However, some bee samples, were contaminated with imidacloprid in concentrations between 14 ng/g and 39 ng/g tissue. We present: the infection of Greek honey bees by multiple viruses; the presence of N. ceranae in Greek honey bees and the first record of imidacloprid (neonicotonoid) residues in Greek honey bee tissues. The presence of multiple pathogens and pesticides made it difficult to associate a single specific cause to the depopulation phenomena observed in Greece, although we believe that viruses and N. ceranae synergistically played the most important role. A follow-up in-depth survey across all Greek regions is required to provide context to these preliminary findings. Copyright © 2010 Elsevier Inc. All rights reserved.

    Full Text Available This paper looks see how meaning is constructed in translated news texts about health and science and awards a narrative potential to unforced translation shifts, moving along the theoretical lines of Baker's Narrative Theory (2006. The thematic thread of health zooms in on “emotional frames” (Nabi, 2003 of risk and fear of human health that is narrated as being 'under attack’ by potentially dangerous diseases. Themes also orbit around schemas that promote hope and optimism about science represented as coming to the rescue of man from fear of the disease. The data consists of 21 pairs of English-Greek health news articles culled from the Greek newspapers I Kathimerini, To Vima and Ta Nea. Findings point towards translation as a process that employs lexicogrammatical and intrasentential configurations to a give emphasis to the risk or hope dimensions underlying a heath or science story, b enable the reflection or emergence of a cascade of public, conceptual and master narratives.

    The development and evolution of Greek Cardiac Surgery (GCS) has followed the international cardiothoracic surgery after the invention of cardiopulmonary bypass machine by John Gibbon in 1953. Chronologically, the development of GCS could be divided in four periods: (a) the first or essay period (1950-1960) characterized by the lack of organization, the experimentation and hesitation from the surgeons' side, and the reluctance from the patients' side to have an operation in Greece. (b) The second or stabilization period (1960-1970) is the period during which several separate cardiovascular departments were organized and performed the first valve replacement in 1964. (c) The third or "strengthening" period (1970-1985), during which Greek surgeons were trained abroad and adopted new methods and techniques of surgical therapy. The first operations of coronary artery bypass grafting and aortic aneurysm were performed (1973-1975). Various purely Cardiothoracic Centers were founded in Athens and Thessalonica and cardiac surgery became a routine operation. However, these centers were numerically not enough to cover the demand of patients in need of cardiac surgery. (d) The fourth or maturity period (1985 till today). It is characterized by the creation of private cardiac surgery departments and the gradual establishment of new university centers at the periphery, which along with the Onassis Cardiac Center, eliminated any need for patients to leave the country.

    2012-01-01

    Full Text Available Background: Trephination, or trepanning, is considered to be one of the most ancient surgical operations with an especially extensive geographical incidence, both in the New World and in the Old. In Europe, more than 200 finds of trephination have been found, from Scandinavia to the Balkans. The technique of trephination or trepanning covers overall the last 10,000 years and exhibits great versatility and adjustability in the knowledge, technical means, therapeutic needs, prejudices and social standards of each period and of each population group. Hippocrates was the one to classify for the first time the kinds of cranial fractures and define the conditions and circumstances for carrying out a trepanning.Aim: The present research aims to investigate the Greek cranial trephinations on sculls from the collection of the Anthropological Museum of the Medical School of Athens that come from archaeological excavations.Method: Skulls were examined by macroscopic observation with reflective light. Furthermore, radiographic representation of the skulls was used.Results: The anthropological researches and the studies of anthropological skeleton remains that came out during archaeological excavations from different eras and areas have given information about the medical practices in the very important geographic area of Greece and in particular, we referred to cases of Greek trephinations.

    Cyclops are among the best-known monsters of Greek mythology, also mentioned in art and literature. According to the most recent scientific knowledge, the malformations caused by defective development of the anterior brain and midline mesodermal structures include cyclopia (synophthalmos), ethmocephaly, cebocephaly and arrhinencephaly. These severe forebrain lesions often are accompanied by severe systemic malformations, and affected infants rarely survive. Neither true cyclopia nor synophthalmos are compatible with life because an anomalous development of the brain is involved. Thus, it is difficult to assume that ancient Greeks drew their inspiration from an adult patient suffering from cyclopia. Cyclops appear for the first time in literature in Homer's Odyssey (8th-7th century BC) and one of them, Polyphemus, is blinded by the hero of the epic poem. The description of the creature is identical with patients suffering from cyclopia; eyes are fused and above the median eye there is a proboscis, which is the result of an abnormal development of the surface ectodermal structures covering the brain. The next literature appearance of Cyclops is at the end of 7th century BC in "Theogonia", written by Hesiodus. Another interesting description is made by Euripides in his satyr play entitled 'Cyclops' (5th century BC). In conclusion, though it is not certain whether Homer's description of Cyclops was based on his personal experience or the narration of his ancestors, there is no doubt that the ophthalmological disease, cyclopia, was named after this mythical creature.

  17. The Greek crisis: Causes and implications

    Vlamis Prodromos

    2010-01-01

    Full Text Available This paper presents and critically discusses the origins and causes of the Greek fiscal crisis and its implications for the euro currency as well as the SEE economies. In the aftermath of the 2007-2009 financial crisis the enormous increase in sovereign debt has emerged as an important negative outcome, since public debt was dramatically increased in an effort by the US and the European governments to reduce the accumulated growth of private debt in the years preceding the recent financial turmoil. Although Greece is the country member of the eurozone that has been in the middle of this ongoing debt crisis, since November 2009 when it was made clear that its budget deficit and mainly its public debt were not sustainable, Greece’s fiscal crisis is not directly linked to the 2007 US subprime mortgage loan market crisis. As a result of this negative downturn the Greek government happily accepted a rescue plan of 110 billion euros designed and financed by the European Union and the IMF. A lengthy austerity programme and a fiscal consolidation plan have been put forward and are to be implemented in the next three years.

  19. Exploring the genetic architecture and improving genomic prediction accuracy for mastitis and milk production traits in dairy cattle by mapping variants to hepatic transcriptomic regions responsive to intra-mammary infection.

    A better understanding of the genetic architecture of complex traits can contribute to improve genomic prediction. We hypothesized that genomic variants associated with mastitis and milk production traits in dairy cattle are enriched in hepatic transcriptomic regions that are responsive to intra-mammary infection (IMI). Genomic markers [e.g. single nucleotide polymorphisms (SNPs)] from those regions, if included, may improve the predictive ability of a genomic model. We applied a genomic feature best linear unbiased prediction model (GFBLUP) to implement the above strategy by considering the hepatic transcriptomic regions responsive to IMI as genomic features. GFBLUP, an extension of GBLUP, includes a separate genomic effect of SNPs within a genomic feature, and allows differential weighting of the individual marker relationships in the prediction equation. Since GFBLUP is computationally intensive, we investigated whether a SNP set test could be a computationally fast way to preselect predictive genomic features. The SNP set test assesses the association between a genomic feature and a trait based on single-SNP genome-wide association studies. We applied these two approaches to mastitis and milk production traits (milk, fat and protein yield) in Holstein (HOL, n = 5056) and Jersey (JER, n = 1231) cattle. We observed that a majority of genomic features were enriched in genomic variants that were associated with mastitis and milk production traits. Compared to GBLUP, the accuracy of genomic prediction with GFBLUP was marginally improved (3.2 to 3.9%) in within-breed prediction. The highest increase (164.4%) in prediction accuracy was observed in across-breed prediction. The significance of genomic features based on the SNP set test were correlated with changes in prediction accuracy of GFBLUP (P layers of biological knowledge to provide novel insights into the biological basis of complex traits, and to improve the accuracy of genomic prediction.

    Over the past 175 years, data related to human disease and death have progressed to a summary measure of population health, the Disability-Adjusted Life Year (DALY). As dairies have intensified there has been no equivalent measure of the impact of disease on the productive life and well-being of animals. The development of a disease-adjusted metric requires a consistent set of disability weights that reflect the relative severity of important diseases. The objective of this study was to use an international survey of dairy authorities to derive disability weights for primary disease categories recorded on dairies. National and international dairy health and management authorities were contacted through professional organizations, dairy industry publications and conferences, and industry contacts. Estimates of minimum, most likely, and maximum disability weights were derived for 12 common dairy cow diseases. Survey participants were asked to estimate the impact of each disease on overall health and milk production. Diseases were classified from 1 (minimal adverse effects) to 10 (death). The data was modelled using BetaPERT distributions to demonstrate the variation in these dynamic disease processes, and to identify the most likely aggregated disability weights for each disease classification. A single disability weight was assigned to each disease using the average of the combined medians for the minimum, most likely, and maximum severity scores. A total of 96 respondents provided estimates of disability weights. The final disability weight values resulted in the following order from least to most severe: retained placenta, diarrhea, ketosis, metritis, mastitis, milk fever, lame (hoof only), calving trauma, left displaced abomasum, pneumonia, musculoskeletal injury (leg, hip, back), and right displaced abomasum. The peaks of the probability density functions indicated that for certain disease states such as retained placenta there was a relatively narrow range of

    Schlenstedt, R; Zschöck, M; Kloppert, B; Wolter, W

    1997-08-01

    During January 1994 and August 1996 from dairy farms in Hessia a total of 305,609 milk samples were investigated. Prototheca sp. as etiological agent of a mastitis was isolated from milk samples of seven dairy herds. According to our experiences and to several reports from various countries dealing with Prototheca infections in dairy herds, mastitis control programs should include Prototheca algae as potential pathogens. Mastitis due to this organism usually occurs in different semeiologies, one with clinical symptoms, and the other, more common type, as subclinical mastitis. In both cases, Prototheca organisms use to persist in the tissue of the mammary gland also during the dry period and antimicrobial treatment proves to be ineffective. Considering the wide distribution of these algae as saprophytes in the environment and in feces of several domestic animals, predisposing factors like a humid aerobic milieu and unsanitary milking conditions are necessary for Prototheca infections becoming manifest in the udder of dairy cows. Control measures should preferably stress the identification and removal of infected animals, in particular when the disease is sporadic in the herd. Due to the more questionable occurrence of spontaneous healing and the lack of an efficient drug, slaughtering of infected cows appears as a suitable method to eliminate the disease from the herd. Additionally, improvement of the hygiene status concerning feeding and milking management within a herd is as essential as in the control of other opportunistic udder pathogens.

This article argues that the faults are very few and minor, and that the early translation (from before 870 CE) should instead be read as a serious example of early Qur’anic interpretation as well as a documentation of early Greek readership of the Qur’an.

    Full Text Available This article presents the Greek influence on the genre of Matthew’s text. Greek and Roman tragedy is examined, from which the five basic elements of tragedy are identified. A brief examination of the characters in the Matthean text is done to identify Greek cultural influences on the structuring of the Gospel. This study offers evidence that Matthew may have intentionally orchestrated a drama with the intent of having an understandable, attractive way to present Jesus to Jew and gentile alike.

    The aim of the present article is to treat the Greek public debt issue strictly as a curve fitting problem. Thus, based on Eurostat data and using the Mathematica technical computing software, an exponential function that best fits the data is determined modelling how the Greek public debt expands with time. Exploring the main features of this best fit model, it is concluded that the Greek public debt cannot possibly be serviced in the long run unless a radical growth is implemented and/or pa...

  9. Astrology in Ancient Greek and Roman Culture

    This article deals with astrology in Greek and Roman culture. It considers astrology's theoretical background, technical basis, interpretative conventions, social functions, religious and political uses, and theory of fate, as well as critiques of it. Astrology is the name given to a series of diverse practices based in the idea that the stars, planets, and other celestial phenomena possess significance and meaning for events on Earth. It assumes a link between Earth and sky in which all existence—spiritual, psychological, and physical—is interconnected. Most premodern cultures practiced a form of astrology. A particularly complex variety of it evolved in Mesopotamia in the first and second millennia BCE from where it was imported into the Hellenistic world from the early 4th century BCE onward. There it became attached to three philosophical schools: those pioneered by Plato, Aristotle, and the Stoics, all of which shared the assumption that the cosmos is a single, living, integrated whole. Hellenistic astrology also drew on Egyptian temple culture, especially the belief that the soul could ascend to the stars. By the 1st century CE the belief in the close link between humanity and the stars had become democratized and diversified into a series of practices and schools of thought that ranged across Greek and Roman culture. It was practiced at the imperial court and in the street. It could be used to predict individual destiny, avert undesirable events, and arrange auspicious moments to launch new enterprises. It could advise on financial fortunes or the condition of one's soul. It was conceived of as natural science and justified by physical influences, or considered to be divination, concerned with communication with the gods and goddesses. In some versions the planets were neither influences nor causes of events on Earth, but timing devices, which indicated the ebb and flow of human affairs, like the hands on a modern clock. Astrology had a radical view of

    2011-12-01

    Full Text Available The Annals of Niketas Choniates depict Emperor Andronikos I Komnenos (1183-1185 in certain aspects of his lifestyle as a mirror image of his first cousin, Emperor Manuel I Komnenos (1143-1180. The life and death of Andronikos I Komnenos provide us with a window into the aesthetic, moral, intellectual, religious, economic and emotional world of Byzantine society in the 12th century. It was thanks to the Byzantine empire that the ancient texts were preserved and transmitted. Ancient Greek culture and reason, in particular, continued to inform Christian values while, at the same time, both could be in radical conflict. The tragic reign of Andronikos as presented by Niketas Choniates conforms to Aristotle's principles of classical drama, but there is a fundamental disagreement between the author of the Poetics and the historian as to what constitutes tragedy, which underlines this conflict.

    Full Text Available Liver transplantation (LT is the only available live-saving procedure for children with irreversible liver failure. This paper reports our experience from the follow-up of 16 Greek children with end-stage liver failure who underwent a LT. Over a period of 15 years, 16 pediatric liver recipients received follow up after being subjected to OLT (orthotopic liver transplantation due to end-stage liver failure. Nine children initially presented with extrahepatic biliary atresia, 2 with acute liver failure after toxic mushroom ingestion, 2 with intrahepatic cholestasis, 2 with metabolic diseases and one with hepatoblastoma. Ten children received a liver transplant in the Organ Transplantation Unit of Aristotle University of Thessaloniki and the rest in other transplant centers. Three transplants came from a living-related donor and 13 from a deceased donor. Six children underwent immunosuppressive treatment with cyclo­sporine, mycophenolate mofetil and corticosteroids, and 7 with tacrolimus, mycophenolate mofetil and corticosteroids. Three out of 16 children died within the first month after the transplantation due to post-transplant complications. Three children presented with acute rejection and one with chronic organ rejection which was successfully managed. Five children presented with cytomegalovirus infection, 5 with Epstein-Barr virus, 2 with HSV1,2, 2 with ParvoB19 virus, 2 with varicella-zoster virus and one with C. Albicans infection. One child presented with upper gastrointestinal hemorrhage and one with small biliary paucity. A satisfying outcome was achieved in most cases, with good graft function, except for the patient with small biliary paucity who required re-transplantation. The long-term clinical course of liver transplanted children is good under the condition that they are attended in specialized centers.

    To identify Greek families in which all members were overweight or obese (XXL families) and to describe their profile with regard to their socio-economic status and their eating behaviours and practices. A prospective cohort study. The metropolitan area of Kavala. We recruited children aged 11 and 12 years from twelve primary schools, and their parents, from volunteers. Auxologic measurements of the children included height and weight. A structured questionnaire pertaining to information on the socio-economic status of the family, anthropometric values and educational status of parents, dietary habits and the availability of various food products and beverages at home, as well as dietary intake, physical activity, time spent sleeping and time spent watching television, was filled in by one of the parents of each child. A total of 331 families finally participated. In sixty-one families (18·43 %) both parents and child were either overweight or obese (XXL family), and in seven of these families all members were obese. Only twenty-eight families (8·46 %) had all members with a normal BMI. The XXL family was associated with lower educational status of both parents, whereas a higher percentage of XXL families resided in rural areas and had lower income. Skipping breakfast and spending more than 3 h in front of a screen every day were more frequently observed in XXL families. With regard to the availability of various food products and beverages at home, no significant differences were observed between XXL families and the rest of the studied families. Greek XXL families have lower educational status and lower annual income.

    2013-12-01

    The presentation of the cult of phallus in ancient Greece and the artistic appearance of the phenomenon on vase figures and statues, as indicative of the significant role of the male genitalia in all fertility ceremonies. The examination of a great number of penile representations from the ancient Greek pottery and sculpture and the review of the ancient theater plays (satiric dramas and comedies ). Phallus in artistic representation is connected either with gods of fertility, such as the goat-footed and horned Pan or the ugly dwarf Priapus or the semi-animal nailed figures Satyrs, devotees of the god Dionysus accompanying him in all ritual orgiastic celebrations. Phallus also symbolizes good luck, health and sexuality: people bear or wear artificial phalli exactly like the actors as part of their costume or carry huge penises during the festive ritual processions. On the contrary, the Olympic gods or the ordinary mortals are not imaged ithyphallic; the ideal type of male beauty epitomized in classical sculpture, normally depicts genitals of average or less than average size. It is noteworthy that many of these images belong to athletes during or immediately after hard exercise with the penis shrunk. The normal size genitalia may have been simply a convention to distinguish normal people from the gods of sexuality and fertility, protectors of the reproductive process of Nature. The representation of the over-sized and erected genitalia on vase figures or statues of ancient Greek art is related to fertility gods such as Priapus, Pan and Satyrs and there is strong evidence that imagination and legend were replacing the scientific achievements in the field of erectile function for many centuries.

  15. Greek paideia and terms of probability

    Directory of Open Access Journals (Sweden)

    Fernando Leon Parada

    2016-06-01

    Full Text Available This paper addresses three aspects of the conceptual framework for a doctoral dissertation research in process in the field of Mathematics Education, in particular, in the subfield of teaching and learning basic concepts of Probability Theory at the College level. It intends to contrast, sustain and elucidate the central statement that the meanings of some of these basic terms used in Probability Theory were not formally defined by any specific theory but relate to primordial ideas developed in Western culture from Ancient Greek myths. The first aspect deals with the notion of uncertainty, with that Greek thinkers described several archaic gods and goddesses of Destiny, like Parcas and Moiras, often personified in the goddess Tyche—Fortuna for the Romans—, as regarded in Werner Jaeger’s “Paideia”. The second aspect treats the idea of hazard from two different approaches: the first approach deals with hazard, denoted by Plato with the already demythologized term ‘tyche’ from the viewpoint of innate knowledge, as Jaeger points out. The second approach deals with hazard from a perspective that could be called “phenomenological”, from which Aristotle attempted to articulate uncertainty with a discourse based on the hypothesis of causality. The term ‘causal’ was opposed both to ‘casual’ and to ‘spontaneous’ (as used in the expression “spontaneous generation”, attributing uncertainty to ignorance of the future, thus respecting causal flow. The third aspect treated in the paper refers to some definitions and etymologies of some other modern words that have become technical terms in current Probability Theory, confirming the above-mentioned main proposition of this paper.

  16. Possible Minoan Contributions to Greek Astronomy

    Science.gov (United States)

    Henriksson, G.; Blomberg, M.

    We present the results of orientation studies of important Minoan monuments and our interpretations of their significance for later Greek astronomy. The studies have been made on the hypothesis that the Minoans, via the Mycenaeans, were the source of the Greek lunisolar calendar and the use of bright stars to signal when to begin activities of economic importance, e.g., ploughing and sailing. The palace at Knossos is oriented so that the first rays of the sun at the equinoxes, as they clear the ridge in the east, will strike an usual concave stone in the floor of the corridor immediately adjacent to the pillar crypt area in the west wing. This area is generally considered to b = e the most sacred part of the first palace. The palace at Zakros is oriented so that from the northern-most corridor of the west wing the moon, as it rose at the southern major standstill, would have been observed to follow the profile of the ridge opposite at the time when the first palace was built (ca 2000 BC). At two peak sanctuaries near Zakros, there are walls oriented such that they could have been used to facilitate observations of the heliacal rising and setting and also the acronychal rising and cosmical setting of the bright star Arcturus ca 1800 BC. In the Minoan ruins of the palaces at Ayia Triada and Mallia, there was constructed a small building of Mycenaean megaron type. Both are oriented to sunset at the summer solstice. We argue from these results that the Minoans had begun systematic observations of the sun, the moon and the bright star Arcturus by the end of the Early Minoan Period (ca 2000 BC). The proximity of Crete to Egypt and the Near East and the documented contact among these regions invite comparison of the calendrical uses of astronomical knowledge in the three areas in the Bronze Age.

  1. Airborne pathogens from dairy manure aerial irrigation and the human health risk

    Borchardt, Mark A.; Burch, Tucker R

    2016-01-01

    Dairy manure, like the fecal excrement from any domesticated or wild animal, can contain pathogens capable of infecting humans and causing illness or even death. Pathogens in dairy manure can be broadly divided into categories of taxonomy or infectiousness. Dividing by taxonomy there are three pathogen groups in dairy manure: viruses (e.g., bovine rotavirus), bacteria (e.g., Salmonella species), and protozoa (e.g., Cryptosporidium parvum). There are two categories of infectiousness for pathogens found in animals: those that are zoonotic and those that are not. A zoonotic pathogen is one that can infect both human and animal hosts. Some zoonotic pathogens found in dairy manure cause illness in both hosts (e.g., Salmonella) while other zoonotic pathogens, like Escherichia coli O157:H7, (enterohemorrhagic E. coli (EHEC)) cause illness only in humans. As a general rule, the gastrointestinal viruses found in dairy manure are not zoonotic. While there are exceptions (e.g., rare reports of bovine rotavirus infecting children), for the most part the viruses in dairy manure are not a human health concern. The primary concerns are the zoonotic bacteria and protozoa in dairy manure.

  2. Developmental surface and phonological dyslexia in both Greek and English.

    Sotiropoulos, Andreas; Hanley, J Richard

    2017-11-01

    The hallmark of developmental surface dyslexia in English and French is inaccurate reading of words with atypical spelling-sound correspondences. According to Douklias, Masterson and Hanley (2009), surface dyslexia can also be observed in Greek (a transparent orthography for reading that does not contain words of this kind). Their findings suggested that surface dyslexia in Greek can be characterized by slow reading of familiar words, and by inaccurate spelling of words with atypical sound-spelling correspondences (Greek is less transparent for spelling than for reading). In this study, we report seven adult cases whose slow reading and impaired spelling accuracy satisfied these criteria for Greek surface dyslexia. When asked to read words with atypical grapheme-phoneme correspondences in English (their second language), their accuracy was severely impaired. A co-occurrence was also observed between impaired spelling of words with atypical phoneme-grapheme correspondences in English and Greek. These co-occurrences provide strong evidence that surface dyslexia genuinely exists in Greek and that slow reading of real words in Greek reflects the same underlying impairment as that which produces inaccurate reading of atypical words in English. Two further individuals were observed with impaired reading and spelling of nonwords in both languages, consistent with developmental phonological dyslexia. Neither of the phonological dyslexics read words slowly. In terms of computational models of reading aloud, these findings suggest that slow reading by dyslexics in transparent orthographies is the consequence of a developmental impairment of the lexical (Coltheart, Rastle, Perry, Langdon, & Zeigler, 2001; Perry, Ziegler, & Zorzi, 2010) or semantic reading route (Plaut, McClelland, Seidenberg, & Patterson, 1996). This outcome provides evidence that the neurophysiological substrate(s) that support the lexical/semantic and the phonological pathways that are involved in reading

    Gammaspectroscopic measurements are taken as an example to describe the monitoring programme of the FRG for monitoring of milk and dairy products. A table shows the number of milk samples taken every year in the FRG in the general environment, and in the vicinity of nuclear installations, together with the radioactivity data obtained by gammaspectroscopy. Due to the decreasing radioactivity as a result of the nuclear weapons tests fallout, the number of samples taken in the general environment has been cut down to half over the period under review. The monitoring capacity set free by this decision has been used during this period for enhanced monitoring of milk and dairy products in regions where nuclear installations such as nuclear power plants have been operating.

    2014-01-01

    This paper presents an extensive analysis of the Greek electricity market for the next 7-year period (2014–2020) based on an hour-by-hour simulation considering five different RES technologies, namely wind, PV, small hydro, biomass and CHP with emphasis on PV integration. The impact of RES penetration on the electricity market operation is evaluated under two different models regarding the organization of the Greek wholesale day-ahead electricity market: a mandatory power pool for year 2014 (current market design) and a power exchange for the period 2015–2020 (Target Model). An integrated software tool is used for the simulation of the current and the future day-ahead market clearing algorithm of the Greek wholesale electricity market. Simulation results indicate the impact of the anticipated large-scale RES integration, in conjunction with each market model, on specific indicators of the Greek electricity market in the long-term. - Highlights: • Analysis of the Greek electricity market for the next 7-year period (2014–2020) based on hour-by-hour simulation. • Five different RES technologies are considered with emphasis on PV integration. • A power pool (for 2014) and a power exchange (for 2015–2020) are considered. • Various market indicators are used for the analysis of the impact of the RES integration on the Greek electricity market. • Two alternative tariff schemes for the compensation of the new ground-mounted PV units from 2015 onwards are investigated

  10. Traditional perception of Greeks in Serbian oral tradition

    Directory of Open Access Journals (Sweden)

    Konjik Ivana

    2006-01-01

    Full Text Available Based on material on Greeks from Vuk’s corpus of epic poems, we discuss the construction of ethnic stereotype of Greeks in Serbian language. However, the limitation of the paper’s possible conclusion lies in the nature of the corpus: Vuk had deliberately chosen one material over another, therefore, the corpus relating to Greeks cannot be considered as representative of the whole Serbian folk poems. Therefore, the discussion is limited to certain elements of the stereotype. Nevertheless, these Serbian epic folk poems contain many layers: historical, geographical, sociological, mythological and so on, with a strong foundation in traditional culture; thus, they provide an insight into geo-political situation of the time period, viewpoints, perspectives and experiences of other ethnic groups that Serbs have been into contact with. In particular, the relationship toward Greeks was marked with pronounced patriarchal attitude concerning others: we-others, ours-foreign, good-bad. In this sense, Greeks are portrayed as foreign, and as such, as a potential source of danger. On the other hand, Greeks are Christian Orthodox, which associates them with the category ours. In socio-economic sense, they were traders and wealthy, respected gentlemen. In epical-heroic profile, they were not considered as great heroes, but as "lousy army", and frequently, as unfaithful.

    2007-11-01

    A whole-farm dairy model was developed and evaluated. The DairyWise model is an empirical model that simulated technical, environmental, and financial processes on a dairy farm. The central component is the FeedSupply model that balanced the herd requirements, as generated by the DairyHerd model, and the supply of homegrown feeds, as generated by the crop models for grassland and corn silage. The output of the FeedSupply model was used as input for several technical, environmental, and economic submodels. The submodels simulated a range of farm aspects such as nitrogen and phosphorus cycling, nitrate leaching, ammonia emissions, greenhouse gas emissions, energy use, and a financial farm budget. The final output was a farm plan describing all material and nutrient flows and the consequences on the environment and economy. Evaluation of DairyWise was performed with 2 data sets consisting of 29 dairy farms. The evaluation showed that DairyWise was able to simulate gross margin, concentrate intake, nitrogen surplus, nitrate concentration in ground water, and crop yields. The variance accounted for ranged from 37 to 84%, and the mean differences between modeled and observed values varied between -5 to +3% per set of farms. We conclude that DairyWise is a powerful tool for integrated scenario development and evaluation for scientists, policy makers, extension workers, teachers and farmers.

    While shedding routes of Coxiella burnetii are identified, the characteristics of Coxiella shedding are still widely unknown, especially in dairy cattle. However, this information is crucial to assess the natural course of Coxiella burnetii infection within a herd and then to elaborate strategies to limit the risks of transmission between animals and to humans. The present study aimed at (i) describing the characteristics of Coxiella burnetii shedding by dairy cows (in milk, vaginal mucus, faeces) in five infected dairy herds, and at (ii) investigating the possible relationships between shedding patterns and serological responses. A total of 145 cows were included in a follow-up consisting of seven concomitant samplings of milk, vaginal mucus, faeces and blood (Day 0, D7, D14, D21, D28, D63, D90). Detection and quantification of Coxiella burnetii titres were performed in milk, vaginal mucus and faeces samples using real-time PCR assay, while antibodies against Coxiella were detected using an ELISA technique. For a given shedding route, and a given periodicity (weekly or monthly), cows were gathered into different shedding kinetic patterns according to the sequence of PCR responses. Distribution of estimated titres in Coxiella burnetii was described according to shedding kinetic patterns. Coxiella burnetii shedding was found scarcely and sporadically in faeces. Vaginal mucus shedding concerned almost 50% of the cows studied and was found intermittently or sporadically, depending on the periodicity considered. Almost 40% of cows were detected as milk shedders, with two predominant shedding patterns: persistent and sporadic, regardless of the sampling periodicity. Significantly higher estimated titres in Coxiella burnetii were observed in cows with persistent shedding patterns suggesting the existence of heavy shedder cows. These latter cows were mostly, persistently highly-seropositive, suggesting that repeated serological testings could be a reliable tool to screen

All students of the aforementioned schools were asked to complete an anonymous questionnaire. Around 62 % of the high school students experienced cyberbullying by electronic means, especially by cell phone, mostly the public school students (p 0.008). The bully was a stranger in more than 40 % of the cases. Over 60 % of the victims had not seeked help but dealt with the attack on their own. Only 20 % of the victims manifested sleep or eating disorders, physical/ psychological symptoms or changes in their social life as a consequence of the cyber-attack. Cyberbullying is a usual phenomenon among high school students. The bully is frequently unacquainted to the victim. Most of the victims are not physically or psychologically affected by the cyber-attack and do not share the event with anyone. There was a slight difference in the response of the students to cyberbullying among the different school politics of on-line aggression.

    To determine the epidemiological characteristics of severe eye injuries in childhood, in a mixed urban and rural Greek setting. Retrospective analysis of 95 cases (103 eyes) of eye injuries in children younger than 17 years of age admitted to the Department of Ophthalmology, University Hospital of Patras, Greece, during a five-year period. The data were analyzed with respect to age, sex, type, cause and mode of injury, method of management, duration of hospitalization and final visual deficit. The average age was 9.8 years and males were involved in 80% of the cases. The most common type of eye injury was mechanical closed-globe injury (71.8%). Mechanical open-globe injuries were found in 21.3% of the eyes, while burns comprised 6.7% of the injuries. Most injuries were agent-related, with blows and falls being responsible most often. Multiple operations were part of the treatment in 11.6% of the eyes; 14.5% of the eyes were blinded and 15.5% had significant final visual acuity loss. These hospital-based data suggest that there is a need for health education of both parents and children, since some injuries in children could easily have been prevented.

    Available studies on surrogacy are extremely limited. Findings suggest that surrogacy is experienced as problem free, with a significant number of commissioning mothers maintaining contact with the surrogates over time. To explore the experiences of Greek commissioning women regarding the surrogacy arrangement and birth of a child through surrogacy. The data of this study were collected from 7 intended mothers who had either a long history of infertility or serious health problems. Interviews were tape-recorded, transcribed and analysed employing content analysis. The analysis of the women's accounts revealed three themes: (a) a shared journey, (b) the birth of a long-awaited child, and (c) the surrogacy disclosure. The surrogacy process became the women's affairs, with their partners offering backstage support. A very close bond was developed with the surrogates, characterised by daily contacts and care-giving behaviours. While this bond was abruptly discontinued after the child's birth, it was interiorised with all participants being grateful to their surrogate. The timing and content of the surrogacy disclosure to family and child(ren) were carefully chosen by participants, who avoided providing information when egg donation was involved. Findings are reassuring for women who want to parent a child through a surrogate arrangement, and suggest that the availability of counselling services may help intended mothers to cope with disclosure issues.

  18. Methodological remarks on studying prehistoric Greek religion

    Directory of Open Access Journals (Sweden)

    Petra Pakkanen

    1999-01-01

    Full Text Available This paper presents a methodological approach to the study of Greek religion of the period which lacks written documents, i.e. prehistory. The assumptions and interpretations of religion of that time have to be based on archaeological material. How do we define religion and cultic activity on the basis of primary archaeological material from this period, and which are the methodological tools for this difficult task? By asking questions on the nature and definition of religion and culture scholars of religion have provided us with some methodological apparatus to approach religion of the past in general, but there are models developed by archaeologists as well. Critical combination of these methodological tools leads to the best possible result. Archaeology studies the material culture of the past. History of religion studies the spiritual culture of the past. In the background the two have important theoretical and even philosophical speculations since they both deal with meanings (of things or practices and with interpretation.

  19. Uncertainty of Volatility Estimates from Heston Greeks

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Volatility is a widely recognized measure of market risk. As volatility is not observed it has to be estimated from market prices, i.e., as the implied volatility from option prices. The volatility index VIX making volatility a tradeable asset in its own right is computed from near- and next-term put and call options on the S&P 500 with more than 23 days and less than 37 days to expiration and non-vanishing bid. In the present paper we quantify the information content of the constituents of the VIX about the volatility of the S&P 500 in terms of the Fisher information matrix. Assuming that observed option prices are centered on the theoretical price provided by Heston's model perturbed by additive Gaussian noise we relate their Fisher information matrix to the Greeks in the Heston model. We find that the prices of options contained in the VIX basket allow for reliable estimates of the volatility of the S&P 500 with negligible uncertainty as long as volatility is large enough. Interestingly, if volatility drops below a critical value of roughly 3%, inferences from option prices become imprecise because Vega, the derivative of a European option w.r.t. volatility, and thereby the Fisher information nearly vanishes.

  20. Greek College Students and Psychopathology: New Insights

    2015-04-01

    Full Text Available Background: College students’ mental health problems include depression, anxiety, panic disorders, phobias and obsessive compulsive thoughts. Aims: To investigate Greek college students’ psychopathology. Methods: During the initial evaluation, 638 college students were assessed through the following psychometric questionnaires: (a Eysenck Personality Questionnaire (EPQ; (b The Symptom Checklist-90 (SCL-90; (c The Beck Depression Inventory (BDI; (d State-Trait Anxiety Inventory (STAI. Results: State anxiety and trait anxiety were correlated, to a statistically significant degree, with the family status of the students (p = 0.024 and the past visits to the psychiatrist (p = 0.039 respectively. The subscale of psychoticism is significantly related with the students’ origin, school, family status and semester. The subscale of neuroticism is significantly related with the students’ school. The subscale of extraversion is significantly related with the students’ family psychiatric history. Students, whose place of origin is Attica, have on average higher scores in somatization, phobic anxiety and paranoid ideation than the other students. Students from abroad have, on average, higher scores in interpersonal sensitivity and psychoticism than students who hail from other parts of Greece. The majority of the students (79.7% do not suffer from depression, according to the Beck’s depression inventory scale. Conclusions: Anxiety, somatization, personality traits and depression are related with the students’ college life.

  4. New Measurements of the Azimuthal Alignments of Greek Temples

    1998-12-01

    The canonical opinion about the placement of Greek temples is that they are oriented east-west (Dinsmoor 1975). Major exceptions, such as the temple of Apollo at Bassae which faces north-south, are always noted in the handbooks, but many other temples are scattered across the Greek landscape in a variety of orientations. Although no surviving ancient author ever discusses the criteria for placing or orienting temples, we may assume from scattered remarks that Greeks had reasons for choosing the sites and orientations. In the last century, archaeologists and architects such as Nissen (1896), Penrose (1893) and Dinsmoor (1939), have measured the alignments of Greek temples on the Greek mainland, the west coast of Turkey, and the Aegean islands. Their data have varying degrees of precision and accuracy, as a recent paper by Papathanassiou (1994) makes clear. Parallel work done in Italy on Etruscan temples by Aveni and Romano (1994) provides further stimulus to re-investigate Greek temples. We have undertaken two field seasons in Greece to make preliminary measurements for a number of temples associated with Athena, Apollo, and Zeus. These temples were chosen for a number of reasons. The structures have to be well enough preserved to allow determination of the orientation of foundations, location of doorways and other openings, placement of cult statues etc. By focusing on these three gods, we may be able to discover patterns in the orientation and placement for specific divinities. For some of these questions, we are dependent on literary and inscriptional evidence, such as the work of the Greek travel writer, Pausanias. This paper describes the preliminary measurements made over our two field seasons in Greece. Field methods and analysis of the data will be presented along with proposed applications.

  5. Dairy Proteins and Energy Balance

    DEFF Research Database (Denmark)

    Bendtsen, Line Quist

    High protein diets affect energy balance beneficially through decreased hunger, enhanced satiety and increased energy expenditure. Dairy products are a major source of protein. Dairy proteins are comprised of two classes, casein (80%) and whey proteins (20%), which are both of high quality......, but casein is absorbed slowly and whey is absorbed rapidly. The present PhD study investigated the effects of total dairy proteins, whey, and casein, on energy balance and the mechanisms behind any differences in the effects of the specific proteins. The results do not support the hypothesis that dairy...... proteins, whey or casein are more beneficial than other protein sources in the regulation of energy balance, and suggest that dairy proteins, whey or casein seem to play only a minor role, if any, in the prevention and treatment of obesity....

    1999-01-01

    This study examines the factors influencing adoption of three related dairy technologies in the coastal Kenya and assessed the impact of dairy adoption on household income, employment generation, and nutritional status of pre-school children. The technologies studied were adoption of grade and crossbred dairy animals, planting of the fodder Napier grass, and use of the infection-and-treatment method of immunisation against East Coast fever. A series of household surveys was conducted from mid-1997 to mid-1998. Results showed that adoption of grade or crossbred dairy animal can lead to substantial impacts on household income, can generate employment, and can have a beneficial impact on the nutritional status of pre-school-age children in the household. It appears that neither the adoption nor productivity of dairying are constrained by poor availability of technology options. For dairy development activities on the coast, two areas merit attention: mechanisms for easing access to grade and crossbred dairy cattle, either through credit schemes or through self-help smallholder co-operatives, and reducing the disease risks associated with grade and crossbred dairy animals

    A cross-sectional study was undertaken (October 2010 to August 2011) to determine the risk factors for dairy goat herds and dairy sheep flocks testing positive for paratuberculosis (PTB) in Ontario, Canada. A questionnaire was administered to 50 producers during a farm visit in which concurrently, 20 randomly selected, lactating animals over the age of 2 years underwent sampling for paratuberculosis testing. Only 1 of 50 farms (2.0%) was closed to animal movement, whereas 96.6% of dairy goat farms and 94.1% of sheep farms purchased livestock from other producers. Only 10.3% of dairy goat, and no dairy sheep farms used artificial insemination. Manure was spread on grazing pastures by 65.5% and 70.6% of dairy goat and dairy sheep farms, respectively. Because of the high true-prevalence of paratuberculosis infection detected, no risk factor analysis could be performed. This study demonstrates that biosecurity practices conducive to transmission of PTB are highly prevalent in Ontario small ruminant dairy farms.

    term has an ancient Greek root but it does not exist in the vocabulary of ancient Greek language. Although ancient Greeks did not have a conscious concept of utopia, they, however, dreamt, wrote, proposed – with different aims - what we would call now ( paradoxically using a ‘modern’ term ‘utopic’ worlds. From the archaic to the post-classic period, we find literary expressions of utopic thought in ancient Greek culture. Such expressions constitute the basis of the modern Utopia and Utopianism with their positive and negative implications. This essay takes a more detailed look at the work of Aristophanes, considered one of the greatest Greek playwrights, and inquires whether his comedies can be considered utopias.

    Full Text Available Data on L. hardjo infection of dairy cows in the world pint out its important role in the occurrence of health and economic problem. L. interrogans serotype hardjo has been described as the cause of miscarriages, stillbirts, or the birhs of poorly vital calves, agalactia, mastitis, and low fertility in cows. Two L. hardjo genotypes have been identified in cows, namely, hardjopraitno and hardjobovis. Serological investigations have established a drastic increase in this leptospiral infection in cows. L. hardjo has become adapted to cattle as the primary host, so that an infection is maintained in herds and becomes deeply rooted because of the permanent presence of the source of infection. It was believed that sheep were accidental hosts, but the latest research suggest that they are yet another, transitory, host for maintining this leptospira serotype. L. hardjo is also important from the aspect of human health, especially of persons who are professionally exposed to this infection. L. hardjo infection is detected using serological tests and by proving the presence of leptospira. The medicine of choice in the therapy of leptospiral infections is streptomycin (DSM. Therapy using oxytetracyclines for clinical mastitis was also proven effective. Treatment is most successful in the early stage of the disease. A single dose of streptomycin administered in infected herds reduces the duration period of leptospira excretion through urine, thus preventing the spread of infection thorugh contaminated urine. The basic components of the plan to contain leptospira are the following: serological investigations, sanitary-higiene measures, the elimination of animals which excrete leptospira through urine, therapy, vaccination, quarantine.

    Full Text Available In this study, we identified Cryptosporidium species and genotypes present in dairy cattle in the central region of São Paulo state, Brazil. Fecal specimens were collected from 200 animals (100 calves and 100 cows in ten dairy farms. Fecal samples were examined using microscopic examination (ME, enzyme immunoassay (EIA and polymerase chain reaction (PCR. Cryptosporidiumspecies and genotypes were determined by restriction fragment length polymorphism (RFLP or DNA sequencing analysis of the SSU-rRNA and GP60 genes. The occurrence of Cryptosporidium spp. infection was 14% (28/200. The occurrence in calves (26% was significantly higher than in cows (2%. Of the 27 Cryptosporidium-positive specimens submitted to genotyping, C. andersoni was identified in 23 (85.1%, C. bovis in three (11.1%, and the zoonotic C. parvum subtype IIaA15G2R1 in one (3.7%. The study demonstrates thatCryptosporidium spp. infection was common and widespread in dairy cattle in this region and that calves have a high prevalence of C. andersoni. Furthermore, the presence of C. parvumsubtype IIaA15G2R1 indicates that dairy calves from this region should be considered a potential source of zoonotic Cryptosporidiumoocysts.

    Full Text Available Since it erupted in 2009, the Greek debt crisis has disrupted Greek people’s quotidian life both at a socio-political and at a personal level. In the contemporary social media ecosystem, with the massive bulk of user-produced and user-consumed content, narratives that concern this critical turning point in Greek modern history have found fertile soil to thrive. In this article, having enmeshed discourse-centered online ethnography (Androutsopoulos, 2008 with small stories research (Georgakopoulou, 2007, the dimensional approach to narratives (Ochs & Capps, 2001, and stance-taking (Du Bois, 2007, I look at how a Greek Facebook user has recounted her emotions, thoughts, opinions, and assessments toward the Greek crisis. In doing so, I point to the intertextual, multimodal, and synergetic nature of these narratives. The article argues that Facebook can function as a powerful grassroots channel for expressive storytelling within a period of major socio-political upheaval. It also shows how Facebook has stretched our conception of what (digital storytelling is as different Facebook affordances propel into different ways of narrating within the medium.

    2003-01-01

    Full Text Available The paper is an overview of the results obtained up to date from the combustion and co-combustion activities with Greek brown coal in different installations, both in semi-industrial and laboratory scale. Combustion tests with Greek lignite were realized in three different Circulating Fluidized Bed Combustion (CFBC facilities. Low rank lignite was burned in a pilot scale facility of approx. 100kW thermal capacity, located in Athens (NTUA and a semi-industrial scale of 1.2 MW thermal capacity, located at RWE's power station Niederaussem in Germany. Co-combustion tests with Greek xylitic lignite and waste wood were carried out in the 1 MWth CFBC installation of AE&E, in Austria. Lab-scale co-combustion tests of Greek pre-dried lignite with biomass were accomplished in a bubbling fluidized bed in order to investigate ash melting problems. The obtained results of all aforementioned activities showed that fluidized bed is the appropriate combustion technology to efficiently exploit the low quality Greek brown coal either alone or in conjunction with biomass species.

    1987-03-01

    This study examines groups of Greek migrant mothers and their attitudes towards their children in different stages of the migratory process. There were 2 lots of samples of Greek migrants mothers who had at least 2 children 8-10 years old, 1 from the home country (5 villages of the District Drama in East Macedonia) and 1 from the receiving country (the area of Baden-Wurtenberg, where most of the migrants from East Macedonia are living). The 4 groups are: 1) 20 mothers who have always lived with their child in the host country; 2) 20 mothers who live in the host country where their child has joined them in the last 2-4 years; 3) 27 mothers who have lived in the host country with their child and have returned home in the last 2-4 years; and 4) 24 non-migrant mothers who have always lived with their families in the home country (control group). Women were interviewed using 2 questionnaires: a survey and an attitude questionnaire. The range of mothers' ages was 20-50 years. The youngest mothers were in the control group whereas group 1 mothers were the oldest. Groups 1 and 2 were mostly unskilled workers; groups 3 and 4 were mostly housewives. The returnees stayed in the host country a mean of 10 years, whereas the other 2 migrant groups were there 14.6 years. There were significantly fewer children in the families of groups 1 and 2 than 3 and 4. The attitude questionnaire covered the following child rearing practices: 1) training the child to participate in home duties; 2) keeping clean and tidy; 3) self-reliance and social behavior towards visitors; 4) ways of dealing with a child's obedience/disobedience; 5) dealing with favor-seeking behavior, food, and sleeping problems; and 6) mother's degree of permissiveness, supervision, and intervention on child's personal and interpersonal sphere of life. Findings show that moving from home to host country and coming back home creates the most controlling mothers, probably because mothers and children face anxiety

    Full Text Available The survival of classics in the People’s Republic of Slovenia after World War II was dominated by the long shadow of the Coryphaeus of the Sciences, Joseph Stalin. Since 1945, the profile of the discipline was determined by the Communist Party, which followed the Soviet example, well-nigh destroying the classical education in the process. Fran Bradač, head of Classics at the University of Ljubljana, was removed for political reasons; the classical gymnasium belonging to the Church was closed down; Greek was struck from the curriculum of the two remaining state classical gymnasia; Latin, previously a central subject at every gymnasium, was severely reduced in 1945, only to disappear entirely in 1946. The classicists who continued to teach were forced to take ‘reorientation courses’ which enabled them to teach Russian and other more suitable subjects. By 1949, only two out of the 42 classicists employed by the Ministry of Education were actually teaching Latin. The Classics department at the university, where only two students were studying in 1949, was on the brink of closure.  Paradoxically, the classical tradition was saved by Stalin’s attack on the same Party. The Cominform conflict in 1948 astonished the Yugoslav communists and pushed them towards a tactical détente with the West, prompting a revision of some of their policies, including education. The process was led by the top echelons of the Party — such as Milovan Djilas, head of the central Agitprop, Boris Kidrič, in charge of Yugoslav economy, and Edvard Kardelj, the Party’s chief ideologue — during the Third Plenum of the Central Committee Politburo in Belgrade in December 1949. Their newly discovered love of Latin and Greek, documented in the minutes of the Politburo Plenum, was overseen only by the discriminating eye of Josip Broz Tito. Classical gymnasia were revived, Latin was reintroduced to some of the other gymnasia, students returned to study classics at the

    Corleto, L M

    1992-01-01

    Coverage of the concept of mania in late archaic Greek culture displays a clear difference between its use in medical and philosophical works. Medical literature uses the terms [Greek] and [Greek] to describe mania, with the condition seen largely associated with physical illness. Specific treatment for this attered psychic state is not advanced. The philosophical view sees mania as a divine folly and thus possessing positive as well as negative aspects. Plate identifies four types of mania and treatment is closely associated with the divinity seen as responsible for that particular type. The radical rationalism found in the medical literature is a counterpoint to moderation as shown by Plato with his interest on regulations of society.

    2012-01-01

    Burnout symptoms in Greek intensive care unit (ICU) nurses have not been explored adequately. The aim of this descriptive, correlational study was to investigate the prevalence and intensity of burnout symptoms in Greek ICU nursing personnel and any potential associations with professional satisfaction, as well as with demographic, educational, and vocational characteristics. Findings showed that the overall burnout level reported by Greek ICU nursing personnel was at a moderate to high degree. The most pronounced symptom of burnout was depersonalization, whereas emotional exhaustion was found to be a strong predictor of job satisfaction. This is a factor connected with the nurses' intention to quit the job. It appears that work factors have a more powerful influence over the development of burnout in comparison to personality traits.

    We reviewed many of the essential Greek myths to identify the methods used at that time to relieve the pain of both illness and surgery, and we discovered many pioneering methods. Both gods and demigods implemented these methods to ease pain, to conduct surgery, and, on occasion, to kill mythological beings. The myths describe the three most common components of anesthesia: hypnosis, amnesia, and (an)algesia. Drugs and music-aided hypnosis were two of the most common methods use to treat emotional and surgical pain. This article identifies highlights in the development of concepts to treat pain in Greek mythology. The examples found in the Greek myths remind us of the historical significance of pain treatment.

These passages testify the initial steps taken by Greek scientists in building a theoretical model of the human body. In these excerpts, one finds erroneous anatomical descriptions, which shed light on the epistemological approach used by these intellectual pioneers. Because of the lack of systematic dissection, it appears that early Greek anatomists developed a somewhat stylized idea of the human body that used a certain degree of symmetry. Overcoming the concept of a strict left-right bilateral parallelism in human body architecture was a challenging intellectual task that required prolonged observation of dissected corpses.

    The incidence rate of cervical cancer varies by geographic region, with less developed regions showing the highest rates. All risk factors for cervical cancer are actually preventable if appropriate lifestyle changes are adopted. In addition, vaccines protecting against the majority of human papilloma virus (HPV) high-risk types have been developed. Even though cervical cancer is preventable, not all women are aware of this or how it can be prevented. Thus, it is essential for every nation to assess the level of knowledge among women of cervical cancer and HPV prevention. In this work, we assessed the level of awareness and attitudes of Greek female healthcare workers on cervical cancer and HPV prevention through the delivery of a validated questionnaire between March and June 2012 in three hospitals in Greece. Our results show that there exist gaps in the knowledge of women on this topic, especially in terms of the newest information on cervical cancer prevention through HPV testing and vaccination. In fact, only 80% of surveyed women knew about the existence of HPV testing. We propose that more information needs to be transmitted to Greek women and men on HPV testing and vaccination. Even though the incidence of cervical cancer is not extremely high in Greece, this number can easily change, especially in the face of the economic crisis and the increasing rates of migration, which can result in higher rates of HPV infection in the population if no measures for HPV prevention are implemented.

    We study the Greek and Roman mythology using the network theory. We construct a directed network by using a dictionary of Greek and Roman mythology in which the nodes represent the entries listed in the dictionary and we make directional links from an entry to other entries that appear in its explanatory part. We find that this network is clearly not a random network but a directed scale-free network. Also measuring the various quantities which characterize the mythology network, we analyze t...

  9. GREEKS AND BARBARIANS IN HOMER’S “ODYSSEY”

    2013-05-01

    Full Text Available Homer’s “Odyssey”, viewed as a relevant literary source for Archaic Greece, has led to the development of different research domains through the medium of hermeneutics or text interpretation. One of these directions regards the reconstitution of social aspects pertaining to the Archaic Greek world. Given that Odysseus’ adventures unfold beyond the borders of the world known by the hero, Greek identity can only be rendered by exclusion, the exclusion of the Other: the reverse of the reprehensible deeds or aspects of the Other comes to define the real, or at least desirable, characteristics of the one operating the exclusion.

    2009-01-01

    Greek philosophy finds its roots in the myth of Homer's and Hesiod's poems and especially in Orphism which introduced the concept of a soul separated from the body with an independent principle, psiche (soul), to be rewarded or punished after death. Orphism was an important step in Greek culture. It introduced the divine into man, the soul which does not die with the body and reincarnates. From Orphism started the need of rituals capable of separating the spirit from the body. From Homer to Acusilaos, water was a very important element which connected humans and gods, long before Thales of Miletus defined it the arche.

    The paper reflects a basic premise: Greek participation in the Euro-zone marked a definitive institutional break in the process of contracting and managing public debt. Instead of internal debt, used extensively in earlier decades, euro-denominated sovereign issues were now placed in the international market. Thus, the Greek state became a net ‘exporter’ of financial claims to an extent unprecedented in its recent history. In assessing the prolegomena to crisis, I offer a review of the post-j...

    2017-12-01

    Full Text Available Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, mainly through the process of replacing or including beneficial bacteria in the gastrointestinal tract. Fermented dairy foods such as yogurt, fermented milk and cheese are the major vehicle in delivering probiotics, and probiotic delivery have been traditionally associated with these fermented dairy foods. Additionally, many other non-dairy probiotic products and non-food form such as capsules, pills and tablets are also available and some of these non-food forms are highly popular among the consumers. Certain non-dairy probiotic foods, especially beverages that are non-fermented products, can also play an important role in probiotic delivery. There is an increasing demand for non-dairy probiotic foods (both fermented and non-fermented including fruit and vegetable juices, soy and certain cereal products due to vegetarianism, lactose intolerance and dairy allergies, as well as interest in low cholesterol foods. In this context, this review mainly focus on the different types of probiotic food products including beverages with special reference to their viability followed by a brief account on the applicability of using fermented and non-fermented beverage products in probiotic delivery.

    2017-12-01

    Full Text Available Probiotic products available in the markets today, are usually in the form of fermented milk products. Dairy consumption have been limited by lactose intolerance and the cholesterol content in dairy products. Besides, traditions and economic reasons that limit the use of dairy fermented products in some developing countries promote the idea of using of alternative raw materials as vehicles for the probiotic agents. For these reasons meat products, cereals, legumes, fruits and vegetables may be potential substrates, where the healthy probiotic bacteria will make their mark, amongst consumers. To develop of these products is a key research priority for food design and a challenge for both industry and science sectors. In this study, information’s were given about non-dairy probiotic foods and highlighting the researches done in this field.

    Madsen, Torben Gosvig; Nielsen, Mette Benedicte Olaf; Andersen, Jens Bech

    2008-01-01

    Reports over the past decade have indicated that normal lactational performance can be achieved in genetically superior and high-producing dairy cows, even when the dry period between 2 lactations is omitted. The hypothesis tested in this experiment was that normal lactogenesis I and metabolic...... function may be achievable in continuously milked high-yielding dairy cows as a result of the genetic selection for lactation performance and hence longevity of mammary epithelial cells. The milk production and mammary nutrient uptake in response to omission of the dry period for cows with an expected peak...... milk yield higher than 45 kg/d were studied in 28 Holstein dairy cows managed without bovine somatotropin. Performance and metabolic parameters were followed in late gestation and in the following early lactation. Fourteen cows were milked continuously throughout late gestation, and another 14 dairy...

    1982-10-22

    This short article describes a facility which will incorporate features to allow for the recovery of the methane gas that is produced in the manufacture of cheese and spray-dried whey powder at the site. The dairy plant is expected to produce about 1,385 m/sup 3//day of methane which will supplement the operation of oil burners and replace the annual consumption of 4,000 bbl of heavy fuel oil. In addition, development of the treatment system would eliminate the consumption of 7,200 kWh/day of electrical energy that would otherwise be required to operate an aerobic disposal system. Total annual energy savings, when the project is fully operational in the spring of 1984, are expected to reach $321,000.

    Coleman, D A; Thayne, W V; Dailey, R A

    1985-07-01

    We conducted two studies to determine how herd management practices and traits of individual cows affect performance of the herd and of the cow within a herd. Management practices, reproductive performance of the herd, and relationships between management and reproductive performance were characterized on 83 dairy farms with 7596 cows. Data included 21 management variables (e.g., facilities, herd health program, estrous detection program) and 8 performance variables obtained from Dairy Herd Improvement or unofficial records (e.g., size of herd, production, days open). Although varying among herds, annual average herd incidences of reproductive disorders and reproductive performance were similar to those reported. Managerial practices influenced incidences of retained placenta and uterine infection, days open of cows not bred and of all cows, services per conception, and percentages of herd open more than 100 days and culled for low production. Veterinarian was the most consistent variable influencing herd reproductive performance. Data also were collected from production and lifetime records of 2532 cows in 19 herds. Reproductive performance was affected by season of calving, production, maturity, and reproductive disorders. Several cows with extremely poor reproductive records were maintained.

  10. The Greek Electricity Market Reforms: Political and Regulatory Considerations

    International Nuclear Information System (INIS)

    Danias, Nikolaos; Kim Swales, John; McGregor, Peter

    2013-01-01

    The paper tracks the evolution of the Greek electricity market since the beginning of the liberalization process. Its progress is benchmarked against the criteria suggested by Littlechild (2006b). The Littlechild framework highlights key remaining deficiencies in the stances and policies adopted which need to be resolved in order for liberalization to proceed successfully. The focus is on the agendas of the Greek government, other domestic political forces and the European Union. A central requirement is the clear commitment to liberalization by the Greek government. In particular the government needs to give up political control over the previous vertically integrated, state-controlled electricity firm, Public Power Company (PPC), and allow more decision making powers and genuine independence to the market regulator. Liberalization is rendered more difficult by the present financial and economic crisis in Greece. - Highlights: • Greek electricity market liberalization is benchmarked against the Littlechild standard electricity market reform model. • Although the majority of the model requirements are met, liberalization in Greece is only partially successful. • Some elements of liberalization are qualitatively more significant than others. • More fundamental political economy issues need to be addressed in order for the liberalization to progress. • Financial crisis in Greece adds extra challenges

    Panagiotis Dimitropoulos

    2010-01-01

    Full Text Available The aim of this paper is to analyze the financial performance of the football clubs participating within the first division of the Greek football league for a period of 14 years (1993-2006 and to propose specific actions that need to be taken by both managers and regulators in order to improve the financial stability of the clubs. We perform financial analysis of key accounting ratios extracted from the football club’s annual financial statements in order to explain the particular causes of the recent financial crisis which characterizes the Greek professional football league. The analysis of the clubs’ annual financial statements revealed that the Greek football clubs are highly leveraged, have intense liquidity and profitability problems and face an increased danger of financial distress, despite the increased amounts that football clubs invested during 2005. The above mentioned crisis can be attributed to aggregate financial mismanagement and political inefficiencies during the last fifteen years. The paper proposes specific actions that need to be taken by both managers and regulators in order to improve the financial stability of the clubs and the overall competitiveness of the Greek football league.

    2008-09-01

    The interplay of architecture and acoustics is remarkable in ancient Greek and Roman theaters. Frequently they are nowadays lively performance spaces and the knowledge of the sound field inside them is still an issue of relevant importance. Even if the transition from Greek to Roman theaters can be described with a great architectural detail, a comprehensive and objective approach to the two types of spaces from the acoustical point of view is available at present only as a computer model study [P. Chourmouziadou and J. Kang, "Acoustic evolution of ancient Greek and Roman theaters," Appl. Acoust. 69, re (2007)]. This work addresses the same topic from the experimental point of view, and its aim is to provide a basis to the acoustical evolution from Greek to Roman theater design. First, by means of in situ and scale model measurements, the most important features of the sound field in ancient theaters are clarified and discussed. Then it has been possible to match quantitatively the role of some remarkable architectural design variables with acoustics, and it is seen how this criterion can be used effectively to define different groups of ancient theaters. Finally some more specific wave phenomena are addressed and discussed.

    Staphylococcus aureus is a common mastitis causing pathogen of dairy cattle. Several S. aureus genotypes exist, of which genotype B (GTB) is highly prevalent in Swiss dairy herds. Dairy farming in mountainous regions of Switzerland is characterised by the movement of dairy cattle to communal pasture-based operations at higher altitudes. Cows from different herds of origin share pastures and milking equipment for a period of 2 to 3 months during summer. The aim of this longitudinal observational study was to quantify transmission of S. aureus GTB in communal dairy operations. Cows (n=551) belonging to 7 communal operations were sampled at the beginning and end of the communal period. Transmission parameter β was estimated using a Susceptible-Infectious-Susceptible (SIS) model. The basic reproduction ratio R 0 was subsequently derived using previously published information about the duration of infection. Mean transmission parameter β was estimated to be 0.0232 (95% CI: 0.0197-0.0274). R 0 was 2.6 (95% CI: 2.2-3.0), indicating that S. aureus GTB is capable of causing major outbreaks in Swiss communal dairy operations. This study emphasized the contagious behaviour of S. aureus GTB. Mastitis management in communal dairy operations should be optimized to reduce S. aureus GTB transmission between cows and back to their herds of origin. Copyright © 2016 Elsevier B.V.

    The main characteristics of fly ash from Greek coal-fired boilers are presented in this paper in relation to its exploitation potential. Both fuel and fly ash samples were collected and analyzed according to the ASTM Standards. Apart from the typical analyses (proximate, ultimate, ash analysis and calorific value), an ICP-AES spectrometer was used for the analysis of heavy metals in the ash. Experimental measurements in order to determine the radioactivity content of raw fuel and the fly ash were carried out as well. A representative fly ash sample from Ptolemais power plant was evaluated and tested as filler in Self-Compacting Concrete (SCC). Ashes from the Greek brown coal are classified in type C, most of the fly ash being produced in Ptolemais of Northern Greece, while the rest in Megalopolis. Ptolemais fly ash is rich in calcium compounds, while Megalopolis fly ash contains more pyrite. Increased heavy metal concentrations are observed in the fly ash samples of Greek coal. Greek fly ash appears to have not only pozzolanic but also hydraulic behaviour. Furthermore, Greek fly ash, depending on its origin, may have relatively high natural radioactivity content, reaching in the case of Megalopolis fly ash 1 kBq kg{sup -1} of {sup 226}Ra. The laboratory results showed that fly ashes can be a competitive substitute to conventional limestone filler material in SCC. Fly ash is mostly used in Greece in cement industry replacing cement clinker and aiming to the production of special types of Portland cements. However, a more aggressive utilisation strategy should be developed, since low quantities of the total produced fly ash are currently further utilised. (author)

  17. Alchemy, Chinese versus Greek, an etymological approach: a rejoinder.

    Science.gov (United States)

    Mahdihassan, S

    1988-01-01

    The theory generally accepted maintains that Alchemy arose at Alexandria as a child of Greek culture. It has two names, Chemeia as the earlier and Chumeia as the later. There is another theory that Alchemy arose in China. Its founder was the aged ascetic who longed after drugs of longevity. He first tried jade, next gold and cinnabar, but the ideal was a drug which was red like cinnabar and fire-proof like gold. But what was actually prepared was red colloidal gold or "calcined gold," by grinding gold granules in a decoction of an herb of longevity. It was called Chin-I; Chin = gold and I = plant juice. In Fukin dialect Chin-I = Kim-Iya. This was Arabicized, by pre-Islamic Arabs trading in silk with China, as Kimiya, whence arose Al-Kimiya and finally Al-chemy. It was first accepted by Bucharic speaking Copts in Egypt who transliterated Kimiya = Chemeia, pronouncing it as the Arabs did. With the increase of trade in silk the Chinese also went to Alexandria and helped the Greeks to translate Chin-I as Chrusozomion meaning, gold (making) ferment, instead of gold making plant juice. Consistent with this origin of the word Chemeia is the fact that the earlier Alchemists were not Greeks but probably Bucharic speaks Copts or Egyptians. The consumer of Chin-I or Chemeia became "a drug-made immortal" called Chin-Jen, Golden-Man. This was translated into Greek as Chrusanthropos. Thus the etymoloogy of two Greek words Chrusozomion and Chrusanthropos support the origin of the loan word, Chemeia as Chinese. To save space it is not proposed to discuss the origin of Chumeia.

    Background Control of bovine tuberculosis (bTB) and zoonotic tuberculosis (zTB) has relied upon surveillance and slaughter of infected cattle, milk pasteurisation and public health education. In Cameroon, like many other sub-Saharan African countries, there is limited understanding of current cattle husbandry or milk processing practices or livestock keepers awareness of bTB. This paper describes husbandry and milk processing practices within different Cameroonian cattle keeping communities and bTB awareness in comparison to other infectious diseases. Study design A population based cross-sectional sample of herdsmen and a questionnaire were used to gather data from pastoralists and dairy farmers in the North West Region and Vina Division of Cameroon. Results Pastoralists were predominately male Fulanis who had kept cattle for over a decade. Dairy farmers were non-Fulani and nearly half were female. Pastoralists went on transhumance with their cattle and came into contact with other herds and potential wildlife reservoirs of bTB. Dairy farmers housed their cattle and had little contact with other herds or wildlife. Pastoralists were aware of bTB and other infectious diseases such as foot-and-mouth disease and fasciolosis. These pastoralists were also able to identify clinical signs of these diseases. A similar proportion of dairy farmers were aware of bTB but fewer were aware of foot-and-mouth and fasciolosis. In general, dairy farmers were unable to identify any clinical signs for any of these diseases. Importantly most pastoralists and dairy farmers were unaware that bTB could be transmitted to people by consuming milk. Conclusions Current cattle husbandry practices make the control of bTB in cattle challenging especially in mobile pastoralist herds. Routine test and slaughter control in dairy herds would be tractable but would have profound impact on dairy farmer livelihoods. Prevention of transmission in milk offers the best approach for human risk mitigation

    Shiga toxin (Stx)-producing Escherichia coli (STEC) bacteria are foodborne pathogens responsible for diarrhea and hemolytic-uremic syndrome (HUS). Shiga toxin, the main STEC virulence factor, is encoded by the stx gene located in the genome of a bacteriophage inserted into the bacterial chromosome. The O26:H11 serotype is considered to be the second-most-significant HUS-causing serotype worldwide after O157:H7. STEC O26:H11 bacteria and their stx-negative counterparts have been detected in dairy products. They may convert from the one form to the other by loss or acquisition of Stx phages, potentially confounding food microbiological diagnostic methods based on stx gene detection. Here we investigated the diversity and mobility of Stx phages from human and dairy STEC O26:H11 strains. Evaluation of their rate of in vitro induction, occurring either spontaneously or in the presence of mitomycin C, showed that the Stx2 phages were more inducible overall than Stx1 phages. However, no correlation was found between the Stx phage levels produced and the origin of the strains tested or the phage insertion sites. Morphological analysis by electron microscopy showed that Stx phages from STEC O26:H11 displayed various shapes that were unrelated to Stx1 or Stx2 types. Finally, the levels of sensitivity of stx-negative E. coli O26:H11 to six Stx phages differed among the 17 strains tested and our attempts to convert them into STEC were unsuccessful, indicating that their lysogenization was a rare event.

    The Metacognitions Questionnaire-30 (MCQ-30), developed by Wells and Cartwright-Hatton (2004), represents a multidimensional measure of metacognitive factors considered to be important in the metacognitive model of psychological disorders. The primary aim of the present study was to examine internal consistency, test-retest reliability, convergent validity and the factor structure of the Greek version of the MCQ-30. Moreover, we investigated the associations of the extracted factors with trait anxiety in a Greek sample. The study sample consisted of 547 non-clinical participants (213 males and 334 females). All participants completed the Greek version of the MCQ-30. A subsample of 157 participants also completed the Trait Anxiety subscale of the State -Trait Anxiety Inventory and the Meta-worry subscale of the Anxious Thought Inventory. Thirty participants were retested with the MCQ-30 over a retest interval ranging from three to five weeks. The results confirmed the dimensionality of the MCQ-30 and five factors were extracted consistent with the original English version: (1) positive beliefs about worry, (2) negative beliefs about worry concerning uncontrollability and danger, (3) cognitive confidence, (4) beliefs about the need to control thoughts and the negative consequences of not controlling them, and (5) cognitive selfconsciousness. The MCQ-30 showed high levels of internal consistency and test-retest reliability. The correlation between MCQ-30 total score and AnTI-MW was strong, indicating high level of convergent validity. Moreover, all correlations between MCQ-30 total and subscale scores and STAI-T were significant apart from the correlation between 'cognitive confidence' and trait anxiety. The Greek sample scored higher in the MCQ-30 and its subscales than the English sample in the original study. Women scored significantly higher than men in the overall MCQ-30 and the "uncontrollability and danger" and "need to control thoughts" subscales, whereas no

    Full Text Available Dairy products are an important component in the Western diet and represent a valuable source of nutrients for humans. However, a reliable dairy intake assessment in nutrition research is crucial to correctly elucidate the link between dairy intake and human health. Metabolomics is considered a potential tool for assessment of dietary intake instead of traditional methods, such as food frequency questionnaires, food records, and 24-h recalls. Metabolomics has been successfully applied to discriminate between consumption of different dairy products under different experimental conditions. Moreover, potential metabolites related to dairy intake were identified, although these metabolites need to be further validated in other intervention studies before they can be used as valid biomarkers of dairy consumption. Therefore, this review provides an overview of metabolomics for assessment of dairy intake in order to better clarify the role of dairy products in human nutrition and health.

    Full Text Available Abstract Background To compare the effects of low versus recommended levels of dairy intake on weight maintenance and body composition subsequent to weight loss. Design and Methods Two site (University of Kansas-KU; University of Tennessee-UT, 9 month, randomized trial. Weight loss was baseline to 3 months, weight maintenance was 4 to 9 months. Participants were maintained randomly assigned to low dairy ( 3 servings/d diets for the maintenance phase. Three hundred thirty eight men and women, age: 40.3 ± 7.0 years and BMI: 34.5 ± 3.1, were randomized; Change in weight and body composition (total fat, trunk fat from 4 to 9 months were the primary outcomes. Blood chemistry, blood pressure, resting metabolism, and respiratory quotient were secondary outcomes. Energy intake, calcium intake, dairy intake, and physical activity were measured as process evaluation. Results During weight maintenance, there were no overall significant differences for weight or body composition between the low and recommended dairy groups. A significant site interaction occurred with the low dairy group at KU maintaining weight and body composition and the low dairy group at UT increasing weight and body fat. The recommended dairy group exhibited reductions in plasma 1,25-(OH2-D while no change was observed in the low dairy group. No other differences were found for blood chemistry, blood pressure or physical activity between low and recommended dairy groups. The recommended dairy group showed significantly greater energy intake and lower respiratory quotient compared to the low dairy group. Conclusion Weight maintenance was similar for low and recommended dairy groups. The recommended dairy group exhibited evidence of greater fat oxidation and was able to consume greater energy without greater weight gain compared to the low dairy group. Recommended levels of dairy products may be used during weight maintenance without contributing to weight gain compared to diets low

    Full Text Available Newly purchased animals that enter a herd with high milk production can be infected with pathogens of the mammary gland and are a potential risk of infection to the cows on the farm. This risk cannot be avoided entirely, but it can be minimized by taking biosecurity measures that should be written as a policy developed for biosecurity oversight of veterinary service: when older cows are purchased, they should be bought with complete lactations and SCC records, and bacterial examination of milk from the udder quarters must be negative for pathogens of the udder; newly purchased cows should come from herds in which the geometric mean somatic cell count is less than 200,000. The herd must have individual cow SCC recorded at least bimonthly for the previous 6 months; the herd must not have had any history of Strep. agalactiae infection in the last 2 years, the herd should be BVDV-free or vaccinated, and the herd owner must be honest and willing to provide all this information. Our country has accepted the standards for milk quality and hygienic properties that comply with EU standards. The proposed biosafety measures presented in this paper enable the determination of the health status of the herd and the biosecurity level of mastitis in commercial farming in intensive dairy production.

    To assess the Ca, nutrient and food intake of Greek Orthodox Christian monks during a vegetarian-type fasting week, compared with their normal diet. Dietary data collection (using 7 d weighed food records), anthropometric and blood pressure measurements, as well as serum glucose and lipid analyses, were performed during Palm Sunday week (fasting) and the week following Pentecost Sunday (non-fasting). Mean daily nutrient and food (g/d) intakes were calculated from the food records. The study took place in two monasteries in the Municipality of Heraklion, Crete. The study involved ten healthy monks aged 25-65 years, with BMI > 30 kg/m2, who had been performing fasts for the last 24.4 (SD 10.4) years and lived in monasteries in Crete during April-June 2005. Nutrient and food intake profiles were more favourable during the fasting week, when participants had lower intakes of total and saturated fat and trans-fatty acids, and higher intakes of dietary fibre, Fe, folate, legumes and fish/seafood. Ca intake was lower when participants fasted, whereas consumption of dairy products, meat and eggs increased significantly in the non-fasting week. Systolic blood pressure was significantly higher, whereas blood lipid levels were more favourable during the fasting week. The periodic vegetarianism recommended by the Greek Orthodox Church contributes to the favourable profiles of several biomarkers of health among this sample of monks. The fasting rituals described are an important component of the traditional diet of Crete and should be emphasised in nutrition education programmes promoting this Mediterranean eating pattern.

    Bovine neosporosis is caused by the protozoan Neospora caninum and is one of the major causes of abortion in cows. Cattle are intermediate hosts of this parasite and may have asymptomatic or symptomatic infections. Therefore, the aim of this study was to evaluate oxidative stress marker reactive oxygen species (ROS), thiobarbituric reactive acid substances (TBARS) levels, glutathione S-transferase (GST), adenosine deaminase (ADA), and butyrylcholinesterase (BChE) activities in dairy cows seropositives for N. caninum (asymptomatic or symptomatic). Dairy cows (n=90) were tested by immunofluorescent antibody assay (IFA) for N. caninum and divided accordingly into three groups: the group A (seronegatives, n=30), the group B (seropositives and asymptomatic, n=30), and the group C (seropositives and symptomatic, n=30). It was observed increased levels of TBARS and reduced (Pcows (the group C) compared to seronegatives dairy cows (the group A). Based on these results, it was observed that seropositive animals showed cell damage associated with oxidative stress and inflammation, mainly in those with symptomatic infections. Increased seric ROS levels and BChE activity may have influenced N. caninum pathogenesis in symptomatic animals due to increased cell damage and exacerbated inflammatory response, leading to the development of clinical signs.

    Treatment of subclinical mastitis during lactation can have both direct (individual animal level) and indirect (population level) effects. With a few exceptions, prior research has focused on evaluating the direct effects of mastitis treatment, and to date no controlled field trials have been conducted to test whether beneficial indirect effects of lactation treatment strategies targeting subclinical mastitis can be demonstrated on commercial dairy farms. Furthermore, there is limited knowledge on the impact of such interventions on the population dynamics of specific bacterial strains. The purpose of this study was to test the hypothesis that lactation therapy targeting S. aureus subclinical intramammary infection reduces transmission of S. aureus strains within dairy herds. Pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) were used to determine strain specific infection dynamics in treated and control groups in a split herd trial conducted on 2 commercial dairy farms. The direct effect of 8 days intramammary lactation therapy with pirlimycin hydrochloride was demonstrated by an increased proportion of cure and a reduction in duration of infection in quarters receiving treatment compared to untreated controls. The indirect effect of lactation therapy was demonstrated by reduction of new S. aureus intramammary infections (IMI) caused by the dominant strain type in both herds. Strain typing of representative isolates taken over the duration of all IMI, including pre- and post-treatment isolates, provided more precise estimates of new infection, cure, and re-infection rates. New S. aureus infections in recovered susceptible quarters and the emergence of a new strain type in one herd influenced incidence measures. In addition to demonstrating positive direct effects of lactation therapy, this study provides evidence that treatment of subclinical S. aureus mastitis during lactation can have indirect effects including preventing new IMI and

    Clinical mastitis as a frequently recurrent event can cause substantive economic loss on dairy farms. The reason for recurrent mastitis can be either a persistent infection of the bovine mammary gland by a mastitis pathogen or a reinfection of a quarter or udder after bacteriological cure. The virulence properties of a mastitis pathogen and the cure odds of an individual cow determine the development of persistent infections. Clinical episodes may alternate with periods without symptoms in the course of persistent infections. Strategies to reduce cases of recurrent mastitis have to include improved treatment concepts and measures to decrease new infection rates. The present literature review summarises the knowledge of definitions, frequencies, causes and effects of recurrent mastitis.

    Glucose is the molecule that drives milk production, and insulin plays a pivotal role in the glucose metabolism of dairy cows. The effect of insulin on the glucose metabolism is regulated by the secretion of insulin by the pancreas and the insulin sensitivity of the skeletal muscles, the adipose tissue, and the liver. Insulin resistance may develop as part of physiologic (pregnancy and lactation) and pathologic processes, which may manifest as decreased insulin sensitivity or decreased insulin responsiveness. A good knowledge of the normal physiology of insulin is needed to measure the in vivo insulin resistance of dairy cows. Copyright © 2013 Elsevier Inc. All rights reserved.

Subjects were final-year diploma and degree student nurses (n = 161) from Greece and England. Pictographs (testing knowledge in a pictorial form) were used as a method of data collection. Three anatomical cardiac diagrams were used. Students were asked to label 20 anatomical parts. Final-year English student nurses have better knowledge in the discrete area of cardiac anatomy and physiology (P nurses from different countries. The findings of the study are important because they show differences in anatomical knowledge levels between Greek and English students. More research is needed to explore further different levels of knowledge and education within the European Union and the consequences for nurse decision-making and patient outcomes.

    Full Text Available Options are financial instruments that can be applied in many situations. Options buyers sell risk which is bought by their sellers who are obliged to reduce it as much as possible. It can be done by using hedging strategies based on Greek letters and options values analysis. The author proves that Greek letters are not constant during the time of option’s life. The paper shows to what extent they are influenced by such factors as risk free interest rate, volatility, underlying asset price and time to maturity. The conclusion is that options sellers must play an active role, i.e. follow fluctuations of all these parameters and modify their hedging portfolios regularly.

    Konidaris, Dimitrios N

    2010-10-01

    This paper analyzes the natural desulfurization process taking place in coal-fired units using Greek lignite. The dry scrubbing capability of Greek lignite appears to be extremely high under special conditions, which can make it possible for the units to operate within the legislative limits of sulfur dioxide (SO2) emissions. According to this study on several lignite-fired power stations in northern Greece, it was found that sulfur oxide emissions depend on coal rank, sulfur content, and calorific value. On the other hand, SO2 emission is inversely proportional to the parameter gammaCO2(max), which is equal to the maximum carbon dioxide (CO2) content by volume of dry flue gas under stoichiometric combustion. The desulfurization efficiency is positively correlated to the molar ratio of decomposed calcium carbonate to sulfur and negatively correlated to the free calcium oxide content of fly ash.

    2009-01-01

    This is a historical article about Ancient Greek literature from mythological times until the first centuries AD with regard to the female breast. We endeavoured to collect several elegant narratives on the topic as well as to explore the knowledge of Ancient Greek doctors on the role, physiology and pathology of breast and the treatment of its diseases. We identified such descriptions in myths regarding Amazons, Hercules, Zeus, Hera and Amaltheia. Furthermore, descriptions on the topic were also found in the work of Hippocrates, Aristoteles, Soranos, Alexander of Aphrodisias, Celsus, Archigenis, Leonides, Galen and Oribasius. We may conclude that some of today's medical knowledge or practice regarding the breast was also known in the historical period.

  1. The evolution of Greek fauna since classical times

    2017-02-01

    Full Text Available This article concerns the Greek fauna of classical and late antiquity and changes up to the present day. The main sources for the fauna of antiquity are historical, geographical and zoological texts, as well as descriptions from travellers who visited Greece. The study of the texts of classical and late antiquity was based on the following classical authors: Xenophon, Aristotle, Aristophanes Byzantios, Pliny, Dio Chrysostom, Plutarch, Pausanias and Aelian. Some species that were present in the Greek fauna of classical and late antiquity, such as the lion and the leopard, are today extinct in Greece, whereas some other species that are now common, such as the cat, the chicken and the peacock, were introduced about that time or a little earlier from other regions. Some other species that are also common today, such as the wild rabbit and the pheasant, were unknown at that time, as they appeared later in Greece from other areas.

  2. Adolescents' mental health and the Greek family: preventive aspects.

    Ierodiakonou, C S

    1988-03-01

    Preventive mental health measures can be properly planned only if the various factors leading to the adolescent's personality structure are extensively investigated. Starting with the specific attitudes of a couple towards genetic counselling, the disadvantages of urbanization and of the dissolution of the traditional extended family are discussed with regard to their effect on the younger members. Data are produced concerning the child-rearing practices of Greek in comparison to American parents and their effect on the adolescent's emotional life. Extreme dependence on the family, pressure for school achievements, lack of sexual education, etc. are characteristic of the stresses a Greek adolescent undergoes. Socio-cultural conditions, like immigration, adoption, etc. are shown to have a different psychological effect on an adolescent in Greece than in America. Specific stresses regarding the adolescent's future, like preparing for university entrance examinations, are discussed and preventive measures are proposed.

  3. The Invention of Infertility in the Classical Greek World:

    Flemming, Rebecca

    2013-01-01

    Summary The article examines the understandings of, and responses to, reproductive failure in the classical Greek world. It discusses explanations and treatments for non-procreation in a range of ancient Greek medical texts, focusing on the writings of the Hippocratic Corpus, which devote considerable energy to matters of fertility and generation, and places them alongside the availability of a divine approach to dealing with reproductive disruption, the possibility of asking various deities, including the specialist healing god Asclepius, for assistance in having children. Though the relations between these options are complex, they combine to produce a rich remedial array for those struggling with childlessness, the possibility that any impediment to procreation can be removed. Classical Greece, rather than the nineteenth century, or even 1978, is thus the time when “infertility,” understood as an essentially reversible somatic state, was invented. PMID:24362276

    2017-02-01

    In this quantitative, cross-sectional study, the authors identified the impact of workplace bullying on nursing staff employed at select Greek public hospitals. They conducted the study using the Negative Acts Questionnaire with a convenience sample of 841 participants employed by five Greek hospitals in the 1st Regional Health Authority of Attica. One third of the respondents reported having been psychologically harassed at work in the past 6 months. According to the results, the impact workplace bullying has on nursing staff varies depending on the existence of a supportive familial or friend environment and if nurses parent children. These findings demonstrate the value of family and friend support when coping with workplace bullying.

  5. Hyman Minsky's financial instability hypothesis and the Greek debt crisis

    Directory of Open Access Journals (Sweden)

    Sergey Beshenov

    2015-12-01

    Full Text Available This article attempts to analyze the current debt crisis in Greece based on the financial instability hypothesis developed by Hyman Minsky. This article shows that the hypothesis provides an understanding of how an economy endogenously becomes “financially fragile” and thus prone to crises. The authors analyze how public and private sector behavior in the Greek economy led to the country's debt crisis. In particular, based on a sample of 36 Greek companies, the authors show that between 2001 and 2014, the majority of those companies had switched to fragile financial structures. Special attention is devoted to the negative consequences of applying the neoclassical doctrine of “austerity measures” in Greece as the principal “anti-crisis” concept of mainstream economic science.

    Full Text Available Primary care physicians face challenges in diagnosing and managing gastroesophageal reflux disease (GERD. The Reflux Disease Questionnaire (RDQ meets the standards of validity, reliability, and practicability. This paper reports on the validation of the Greek translation of the RDQ. RDQ is a condition specific instrument. For the validation of the questionnaire, the internal consistency of its items was established using the alpha coefficient of Chronbach. The reproducibility (test-retest reliability was measured by kappa correlation coefficient and the criterion of validity was calculated against the diagnosis of another questionnaire already translated and validated into Greek (IDGP using kappa correlation coefficient. A factor analysis was also performed. Greek RDQ showed a high overall internal consistency (alpha value: 0.91 for individual comparison. All 8 items regarding heartburn and regurgitation, GERD, had good reproducibility (Cohen’s κ 0.60-0.79, while the remaining 4 items about dyspepsia had a moderate reproducibility (Cohen’s κ=’ 0.40-0.59 The kappa coefficient for criterion validity for GERD was rather poor (0.20, 95% CI: 0.04, 0.36 and the overall agreement between the results of the RDQ questionnaire and those based on the IDGP questionnaire was 70.5%. Factor analysis indicated 3 factors with Eigenvalue over 1.0, and responsible for 76.91% of variance. Regurgitation items correlated more strongly with the third component but pain behind sternum and upper stomach pain correlated with the second component. The Greek version of RDQ seems to be a reliable and valid instrument following the pattern of the original questionnaire, and could be used in primary care research in Greece.

We emphasize on uterine's cancer aetiology according to the dominant in antiquity humoural theory, on its surgical treatment suggested by Soranus of Ephesus, and in the vivid description provided by Aretaeus of Cappadocia. During that period, uterine cancer was considered as an incurable and painful malignancy and its approach was mainly palliative.

    2010-06-01

    Full Text Available This essay offers a critique of Ernst Gombrich’s account of the Greek Revolution. I hope to show, however, that three major pivots of his argument -- the initiating rôle of the narrative, the continuing process of the refinement of "realism" and the breakdown of that process in the late Roman Empire cannot bear the weight assigned to them. On careful examination Gombrich's delicately balanced argument, with its artful rhetoric, collapses.

  19. Connectivity Practices and Activity of Greek Political Blogs

    Directory of Open Access Journals (Sweden)

    Kostas Zafiropoulos

    2012-08-01

    Full Text Available This paper uses Social Network Analysis indexes to study Greek political blogs. The indexes describe bloggers’ community recommendations, centrality and bloggers’ attempt to form spheres of influence. Five Social Network Analysis indexes are used: incoming links, normalized betweenness, outgoing links, number of 1-cliques a blog belongs to, and size of blog’s ego-network. By recording 127 Greek political blogs, the paper finds that there are two distinct blog performance properties regarding connectivity: Only a few blogs serve as authority blogs having many incoming links and centrality, while a few others try to expand their influence territory by having many outgoing links and forming larger 1-cliques and ego-networks. Next, the paper associates the proposed indexes with blogs’ and users’ community activity. Authority blogs present high blog activity and users’ community activity, as well. These are recorded by large numbers of posts and comments to the blog posts, respectively. It is shown that blogs, which strive to expand their network by using many outgoing links are more likely to link to the authority blogs. Content analysis reveals that authority blogs provide news and information and promote discussion to a much higher degree compared to the overall Greek political blogosphere.

    Trompoukis, Constantinos; Kourkoutas, Dimitrios

    2007-06-01

    In distant eras, mythology was a form of expression used by many peoples. A study of the Greek myths reveals concealed medical knowledge, in many cases relating to the eye. An analysis was made of the ancient Greek texts for mythological references relating to an understanding of vision, visual abilities, the eye, its congenital and acquired abnormalities, blindness, and eye injuries and their treatment. The Homeric epics contain anatomical descriptions of the eyes and the orbits, and an elementary knowledge of physiology is also apparent. The concept of the visual field can be seen in the myth of Argos Panoptes. Many myths describe external eye disease ("knyzosis"), visual disorders (amaurosis), and cases of blinding that, depending on the story, are ascribed to various causes. In addition, ocular motility abnormalities, congenital anomalies (cyclopia), injuries, and special treatments, such as the "licking" method, are mentioned. The study of mythological references to the eye reveals reliable medical observations of the ancient Greeks, which are concealed within the myths.

    Diabetes knowledge has been shown to improve glycemic control and associate with several demographic parameters. In Greece, a country with high obesity rates, disease knowledge has never been evaluated in diabetic patients. This cross sectional study aimed to assess diabetes knowledge and its associations between social and demographic parameters, among Greek type 2 diabetes mellitus (T2DM) patients. One hundred fifty nine patients with T2DM were recruited from an urban and a rural clinic in Greece. Diabetes knowledge was assessed with the Brief Diabetes Knowledge Test (DKT). Basic anthropometry was performed. Data regarding glycemic control and sociodemographic characteristics were collected from the patients' medical files. Greek T2DM patients demonstrated poor disease knowledge (mean DKT score 8.3±2.2/14.0 and mean DKT as a percent of correct answers 59.6±15.8%). No differences were observed between sex, place of residence, or glycemic control, among subjects. Patients with higher education demonstrated greater diabetes knowledge. Simple obesity with concurrent central obesity or suboptimal glycemic control decreased diabetes knowledge among participants. Additionally, waist circumference was inversely correlated to diabetes knowledge. Based on the DKT, Greek patients exhibit poor diabetes knowledge. This study provides evidence for the need for better diabetes education in order to ameliorate disease outcome. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

    This exploratory research examined adjustment challenges, resiliencies, attitudes, emotional health, economic stability, criminal involvement, victimization and service experiences, and some cultural propensities of Greek Immigrants (GIs) in Australia using a convenient multi-generational sample (n = 123; response rate = .5). Data were collected via surveys, telephone, and personal-interviews in four major Australian cities. Among other things, the study revealed that Greek identity and cultural customs are often significant to first generation GIs. Adjustment challenges upon entry include primarily language, housing, and transportation difficulties, nostalgia for relatives and the motherland, unfamiliarity with socio-cultural systems, unemployment, money challenges, and lack of friendships. Christian faith, the extended family, family values and traditions, cultural pride for ancient Greek achievements, and a hard 'work ethic' are notable resiliencies that support GIs in their struggles and solidify their pursuit for happiness and success. Financial concerns, aging, and nostalgia for relatives and the motherland were the primary causes of socio-emotional instability. Attitudinal differences in the respondents based on age, gender, and socio-economic status, cross-cultural comparisons, and recommendations for culturally-sensitive practice with GIs are analyzed and methodological limitations illuminated. Future research needs in the field are also highlighted.

    In March 2011, a migrant health project became operational that aimed to provide medical and psychosocial support to migrants at the Greek-Turkish border. The aim of this study is to describe common syndromes, the communicable disease profile and vaccination patterns in newly arrived migrants through a surveillance system that was based on medical records data as well as screening procedures. Data were collected prospectively using one standardized form per patient including demographic information, civil status, and medical and vaccination history. A tuberculin screening test (TST) and serological testing for HIV, hepatitis B and hepatitis C were performed after obtaining informed consent. A total of 6899 migrants were screened, the majority of whom were male (91%) and 18-31 years old (85%), with a mean age of 25.3 years. Of all patients, 2.5% received secondary care. Common complaints and diagnoses included respiratory infections (23%) and myalgia (18%). The tuberculin screening test (TST) was positive in 7.8% out of 1132 patients tested. Out of 632 migrants, 0.3%, 3.2% and 0.8% tested positive for HIV, hepatitis B and hepatitis C, respectively. Overall, 22.3% of adults were vaccinated against poliomyelitis. Irregular migrants that enter Greek borders are generally in good health. Nevertheless, the risk of spreading communicable diseases is an important issue to consider among migrants at the holding level due to severe overcrowding conditions. Therefore, there is a need to strengthen surveillance and implement harmonized screening procedures with the aim of providing sustainable and good quality services that are focused on prevention and early treatment.

    Full Text Available The Tanga Dairy Platform, created in 2008, is an informal forum of different stakeholders involved in the dairy industry of Tanzania’s Northeastern Tanga region. The platform’s objective is to exchange knowledge and develop joint actions to common problems. Six years on, it is a sustainable example of a commodity association addressing the joint problems of the region’s dairy industry. The platform has achieved a common understanding among chain actors on dairy price structure; it has successfully lobbied policy makers to reduce value-added tax on dairy inputs and products, and to remove limitations on urban dairy farming in Tanga city.

    Full Text Available This article is devoted to the problem of the value orientations of modern young people, who begin their independent life in the current conditions of the difficult changes in the political, social and economic life of the countries. Greece and Russia are two of the countries, which are in crisis due to the globalisation processes. The article gives the details of the results of the empirical study of the value orientations in Greek and Russian students and presents their comparative analysis. It identifies the similarity of the value orientations in Greek and Russian students, which appears in the fact that the value of health (it seems quite difficult to achieve and the value of self-development and self-improvement (an easily achievable value are important to the students of both groups; and the values of creativity and financially-secure life (the value, which is difficult to achieve have little significance. The significant differences between the groups lie in the fact, that the Russian group is dominated by the people with the focus on business, the value of interesting work is important to them, they are more focused on business activity, as well as on love, and the interpersonal relations are less significant for them. The Greek students are often focused on themselves, on their families; freedom in actions, confidence and friendship are more important to them. The peculiarities of the value orientations of the Russian students are internally more conflicting: first of all, we are talking of an important value of love and its dissatisfaction, the important value of an interesting job and the idea that it is difficult to achieve these values. The internal conflict of the Greek students often concerns the importance and the low availability of the value of freedom. The study shows that the peculiarities of the value orientations of Russian students reflect the socio-economic changes in the society, while the values of Greek students

    2014-03-01

    The objective of this work was to develop and optimize an alternative make process for Greek-style yogurt (GSY), in which the desired level of protein was reached by fortification with micellar casein concentrate (MCC) obtained from milk by microfiltration. Two MCC preparations with 58 and 88% total protein (MCC-58 and MCC-88) were used to fortify yogurt milk to 9.80% (wt/wt) protein. Strained GSY of similar protein content was used as the control. Yogurt milk bases were inoculated with 0.02% (wt/wt) or 0.04% (wt/wt) direct vat set starter culture and fermented until pH 4.5. The acidification rate was faster for the MCC-fortified GSY than for the control, regardless of the inoculation level, which was attributed to the higher nonprotein nitrogen content in the MCC-fortified milk. Steady shear rate rheological analysis indicated a shear-thinning behavior for all GSY samples, which fitted well with the power law model. Dynamic rheological analysis at 5°C showed a weak frequency dependency of the elastic modulus (G') and viscous modulus (G") for all GSY samples, with G' > G", indicating a weak gel structure. Differences in the magnitude of viscoelastic parameters between the 2 types of GSY were found, with G' of MCC-fortified GSY yogurt. Differences were also noticed in water-holding capacity, which was lower for the MCC-fortified GSY compared with the control, attributed to lower serum protein content in the former. Despite some differences in the physicochemical characteristics of the final product compared with GSY manufactured by straining, the alternative process developed here is a feasible alternative to the traditional GSY make process, with environmental and possibly financial benefits to the dairy industry.

    Full Text Available Several studies have explored the acoustic structure of fricatives, yet there has been very little acoustic research on the effects of dialects on the production of fricatives. This article investigates the effects of two linguistically proximal Modern Greek dialects, Athenian Greek and Cypriot Greek on the temporal, spectral, and coarticulatory properties of fricatives and aims to determine the acoustic properties that convey information about these two dialects. Productions of voiced and voiceless labiodental, dental, alveolar, palatal, and velar fricatives were extracted from a speaking task from typically speaking female adult speakers (25 Cypriot Greek and 20 Athenian Greek speakers. Measures were made of spectral properties, using a spectral moments analysis. The formants of the following vowel were measured and second degree polynomials of the formant contours were calculated. The findings showed that Athenian Greek and Cypriot Greek fricatives differ in all spectral properties across all places of articulation. Also, the co-articulatory effects of fricatives on following vowel were different depending on the dialect. Duration, spectral moments, and the starting frequencies of F1, F2, F3, and F4 contributed the most to the classification of dialect. These findings provide a solid evidence base for the manifestation of dialectal information in the acoustic structure of fricatives.

    Immune thrombocytopenia (ITP) in children has a varied course and according to duration is distinguished as newly diagnosed (12) types. Several studies have evaluated the prognostic factors for the progression of the disease, but similar works have yet to be performed in Greece. We aimed to identify prognostic markers for the three forms of the disease in 57 Greek children during a 13-year period. Information regarding age, gender, preceding infection, bleeding type, duration of symptoms and platelets at diagnosis, treatment, disease course, and immunological markers was recorded. 39 children had newly diagnosed, 4 persistent, and 14 chronic disease. Chronic ITP children were more likely to be of age > 10 years ( p = 0.015) and have gradual initiation of the disease ( p = 0.001), platelets > 10 × 10 9 /L ( p = 0.01), and impaired immunological markers ( p < 0.003) compared to newly diagnosed/persistent groups. Recent history of infection was found mainly in the newly diagnosed/persistent group ( p = 0.013). None of the children exhibited severe spontaneous bleeding. Conclusion . Even though ITP in children usually has a self-limited course, with rare serious bleeding complications, the chronic form of the disease is characterized by different predictive parameters, which can be used in clinical practice.

  4. Skewed Sociolinguistic Awareness of a Native Non-standard Dialect: Evidence from the Cypriot Greek Writing of Greek Cypriot Students

    2017-11-01

    Full Text Available Over the last 50 years, sociolinguistic research in settings in which a regional, social, or ethnic non-standard linguistic variety is used alongside the standard variety of the same language has steadily increased. The educational implications of the concomitant use of such varieties have also received a great deal of research attention. This study deals with regional linguistic variation and its implications for education by focusing on the Greek Cypriot educational context. This context is ideal for investigating the linguistic profiles of speakers of proximal varieties as the majority of Greek Cypriots are primarily educated in just one of their varieties: the standard educational variety. The aim of our study was to understand Greek Cypriot primary school pupils’ sociolinguistic awareness via examination of their written production in their home variety [Cypriot Greek (CG dialect]. Our assumption was that, because written production is less spontaneous than speech, it better reflects pupils’ conscious awareness. Pupils were advised to produce texts that reflected their everyday language with family and friends (beyond school boundaries. As expected, students’ texts included an abundance of mesolectal features and the following were the ten most frequent: (1 palato-alveolar consonants, (2 future particle [ená] and conditional [ítan na] + subjunctive, (3 consonant devoicing, (4 CG-specific verb stems, (5 final [n] retention, (6 [én/ éni] instead of [íne], (7 CG-specific verb endings, (8 [én/é] instead of [ðen], (9 elision of intervocalic fricative [ɣ], and (10 CG-specific adverbs. Importantly, in addition to the expected mesolectal features that reflect contemporary CG, students included a significant and unexpected number of basilectal features and instances of hyperdialectism (that are not representative of today’s linguistic reality which rendered their texts register-inappropriate. This led us to conclude that Greek

  7. Review: Efficiency of physical and chemical treatments on the inactivation of dairy bacteriophages

    Full Text Available Bacteriophages can cause great economic losses due to fermentation failure in dairy plants. Hence, physical and chemical treatments of raw material and/or equipment are mandatory to maintain phage levels as low as possible. Regarding thermal treatments used to kill pathogenic bacteria or achieve longer shelf-life of dairy products, neither low temperature long time (LTLT nor high temperature short time (HTST pasteurization were able to inactivate most lactic acid bacteria (LAB phages. Even though most phages did not survive 90ºC for 2 min, there were some that resisted 90ºC for more than 15 min (conditions suggested by the International Dairy Federation, IDF, for complete phage destruction. Among biocides tested, ethanol showed variable effectiveness in phage inactivation, since only phages infecting dairy cocci and Lactobacillus helveticus were reasonably inactivated by this alcohol, whereas isopropanol was in all cases highly ineffective. In turn, peracetic acid has consistently proved to be very fast and efficient to inactivate dairy phages, whereas efficiency of sodium hypochlorite was variable, even among different phages infecting the same LAB species. Both alkaline chloride foam and ethoxylated nonylphenol with phosphoric acid were remarkably efficient, trait probably related to their highly alkaline or acidic pH values in solution, respectively. Photocatalysis using UV light and TiO2 has been recently reported as a feasible option to industrially inactivate phages infecting diverse LAB species. Processes involving high pressure were barely used for phage inactivation, but until now most studied phages revealed high resistance to these treatments. To conclude, and given the great phage diversity found on dairies, it is always advisable to combine different anti-phage treatments (biocides, heat, high pressure, photocatalysis, rather than using them separately at extreme conditions.

    Somatic cell count (SCC) in monitoring udder health has been described in numerous studies as a useful method for the diagnosis of intramammary infection (IMI), and it is considered in standards of quality and hygiene of cows milk in many countries. However, several authors have questioned the validity of SCC as a reliable IMI diagnosis tool in dairy goats. This review attempts to reflect the importance of different infectious and non-infectious factors that can modify SCC values in goat milk, and must, therefore, be taken into account when using the SCC as a tool in the improvement of udder health and the quality of milk in this species. In dairy goats, some investigations have shown that mammary bacterial infections are a major cause of increased SCC and loss of production. In goats however, the relationship between bacterial infections and SCC values is not as simple as in dairy cattle, since non-infectious factors also have a big impact on SCC. Intrinsic factors are those that depend directly on the animal: time and number of lactation (higher SCC late in lactation and in aged goats), prolificity (higher SCC in multiple births), milking time (higher SCC in evening compared to morning milking) and number of milkings per day, among others. Extrinsic factors include: milking routine (lower SCC in machine than in manual milking), seasonality and food. In addition, milk secretion in goats is mostly apocrine and therefore characterized by the presence of epithelial debris or cytoplasmic particles, which makes the use of DNA specific counters mandatory. All this information is of interest in order to correctly interpret the SCC in goat milk and to establish differential SCC standards. (Author)

    Few data exist concerning the natural history of degenerative osteoarthritis (OA) of the spine and its associated gene investigation. Degenerative spinal OA demonstrates an international prevalence of 15% in the general population. The aim of this Greek case-control study is to examine gene polymorphisms that have been previously shown or hypothesized to be correlated to degenerative OA. Gene polymorphisms, especially for OA, have never been previously studied in the Greek population. The study was conducted from May 2009 to December 2012. Eligible subjects who agreed to take part in the study were Greek adults from all of Greece, referred for consultation to the Palliative Care and Pain Relief Unit of Aretaieion University Hospital, in Athens, Greece. A total of 601 matched pairs (cases and controls) participated in the study, 258 patients (188 women and 70 men) with clinically and radiologically confirmed degenerative OA and 243 control subjects (138 women and 105 men). All patients presented with chronic pain at the spine (cervical, thoracic or lumbar) caused by sympomatic osteophytes or disc narrowing, whereas clinical diagnosis of OA was based on the presence of both joint symptoms and evidence of structural changes seen on plain conventional X-rays. We investigated genetic variation across candidate OA gene GDF5, CDMP1, CDMP2, Asporin, SMAD3, and chromosomal region 7q22, in a sample of 258 patients with clinically and radiologically confirmed degenerative OA, and 243 control subjects from the Greek population. All subjects (patients and controls) were subsequently matched for the epidemiologic, demographic, and clinical risk factors, to prevent selection biases. A tagging single nucleotide polymorphism (SNP) approach was pursued to cover variation across all targeted loci. Single marker tests as well as haplotypic tests of association were performed. There is no conflict of interest, and also, there are no study funding sources. We found significant

    2013-09-01

    Some acoustic characteristics of the two types of vocal music of the Greek Orthodox Church Music, the Byzantine chant (BC) and ecclesiastical speech (ES), are studied in relation to the common Greek speech and the Western opera. Vocal samples were obtained, and their acoustic parameters of sound pressure level (SPL), fundamental frequency (F0), and the long-time average spectrum (LTAS) characteristics were analyzed. Twenty chanters, including two chanters-singers of opera, sang (BC) and read (ES) the same hymn of Byzantine music (BM), the two opera singers sang the same aria of opera, and common speech samples were obtained, and all audio were analyzed. The distribution of SPL values showed that the BC and ES have higher SPL by 9 and 12 dB, respectively, than common speech. The average F0 in ES tends to be lower than the common speech, and the smallest standard deviation (SD) of F0 values characterizes its monotonicity. The tone-scale intervals of BC are close enough to the currently accepted theory with SD equal to 0.24 semitones. The rate and extent of vibrato, which is rare in BC, equals 4.1 Hz and 0.6 semitones, respectively. The average LTAS slope is greatest in BC (+4.5 dB) but smaller than in opera (+5.7 dB). In both BC and ES, instead of a singer's formant appearing in an opera voice, a speaker's formant (SPF) was observed around 3300 Hz, with relative levels of +6.3 and +4.6 dB, respectively. The two vocal types of BM, BC, and ES differ both to each other and common Greek speech and opera style regarding SPL, the mean and SD of F0, the LTAS slope, and the relative level of SPF.

    Greece has the highest adult smoking prevalence in the European Union, affecting not only those who smoke but also threatening the health of those who are involuntarily exposed to passive smoke, especially young Greek children. The aim of this study was to quantify passive smoking biomarkers (serum nicotine and cotinine levels) among preschool children in Crete in relation to parental smoking habits. All children enrolled in kindergarten in western Crete (1,757 preschool children and 2,809 parents) were interviewed during the 2004-2005 Cretan health promotion programme out of which a sample of 81 children was randomly selected according to parental smoking status and blood samples for cotinine and nicotine assay were taken. The geometric means of serum nicotine values in children with both parents current smokers and in those with both parents non-smokers were 0.71 ng/ml (95%CI 0.62, 0.80) and 0.59 ng/ml (95%CI 0.49, 0.69), respectively, (p=0.073). Cotinine geometric mean values were found at 1.69 ng/ml (95%CI 0.93, 3.06) and 0.15 ng/ml (95%CI 0.09, 0.28), respectively, (pparents had also greater cotinine geometric mean values than boys (3.35 versus 0.85 ng/ml, respectively, p=0.018). Our findings prove that Greek preschool children, especially young girls, are exposed to substantial levels of passive smoke which therefore stresses the need for immediate action so as to prevent the predisposition and early addiction of Greek preschool children to tobacco.

    According to Greek legislation the medico-legal investigation of deaths occurring in prisons is mandatory. Furthermore, in cases of suicide or of suspected suicide the contribution of medico-legal investigation is of grave importance. The current paper addresses the medico-legal investigation of suicide cases in Greek correctional facilities and aims to describe the current situation. Our study consists of the meticulous research in the data records of major Greek correctional facilities, for the time period 1999-2010. Official permission was obtained by the Hellenic Ministry of Justice, which provided us the access to the records. Data was also collected from the Piraeus Forensic Service, from the Department of Pathological Anatomy of the University of Athens and finally from our own records. Measures were taken to respect the anonymity of the cases. Data was collected for the social, penal, medical history as well as for the medico-legal investigation. It appears that 85.7% of suicide cases were transferred to the Prisoner's Hospital (p < 0.0001), the forensic pathologist who conducted the PME did not perform scene investigation in none of the 70 suicide cases. In a total of 70 cases, histopathological examination, was requested only in 30 cases (42.9%). Hanging was the preferred method for those who committed suicide, followed by the poisoning due to psychoactive substances. Understanding the mistakes made during the forensic investigation of suicide cases inside correctional facilities is necessary, in order to prevent them from occurring again in the future, by implementing appropriate new policies and guidelines.

    HPV is associated with malignancy in men, yet there is a lack of data on HPV knowledge, vaccine acceptability, and factors affecting vaccine acceptability in Greek men. This study aims to identify determinants of knowledge and willingness to vaccinate against HPV among high-risk Greek men. Men (n = 298) between the ages of 18 and 55 were enrolled from the STI and HIV clinics at "Andreas Syggros" Hospital in Athens, Greece from July-October 2015. Participants completed a survey on demographics, economic factors, sexual history, HPV knowledge, and vaccine acceptability. The majority of participants were younger than 40 (76.6%) and unmarried (84.6%). Our sample was 31.2% MSM (men who have sex with men), and 20.1% were HIV-positive. Most participants (>90%) were aware that HPV is highly prevalent in both men and women; however, fewer identified that HPV causes cancers in both sexes (68%) and that vaccination protects men and women (67%). Amongst participants, 76.7% were willing to vaccinate themselves against HPV, 71.4% an adolescent son, and 69.3% an adolescent daughter. HIV-positive men were more likely to be willing to vaccinate themselves (OR 2.83, p = .015), a son (OR 3.3, p = .015) or a daughter (3.01, p = .020). Higher income levels were associated with increased willingness to vaccinate oneself (OR 1.32, p = .027), a son (1.33, p = .032) or daughter (1.34, p = .027). Although there is a HPV knowledge gap, HPV vaccine acceptability is high despite lack of vaccine promotion to Greek men. Future studies should include lower-risk men to adequately inform public health efforts.

    Full Text Available The theological climate of the young Church of Anglo-Saxon Christians was determined by Irish and Welsh monks maintaining the tradition of the Egyptian desert. The Angles and Saxons had a particular vision of the natural world, of the eternal world, a particular comprehension of sin and repentance. Rome in its missionary work used them to attach the British Christians the see of St Peter. Britain had no original link with the culture and tradition of the classical Church. It has been particularly established and enforced in VII and VIII, when England received a great dose of classical learning and theology due to the activity of archbishop of Canterbury Theodore and monk Hadrian. The formerly Greek monk Theodore – well learned in the Holy Scripture as well as Greek and Latin classics – was named the archbishop of Canterbury by pope Vitalian under the condition that he should notintroduce any typically Greek customs. Theodore named Hadrian the abbot of the Canterbury monastery of St Peter. There and in York young English could pursue classical studies of the Holy Scriptures, poetry, philosophy, mathematics, astronomy, etc. It resulted in significant literary development in Britain, of which venerable Bede is an example.Theodore introduced in Canterbury proto-byzantine canonical law, during two famous synods established doctrinal and ecclesiastical foundations of English Christianity based on ancient orthodox tradition of Eastern part of the Mediterranean region. At the Synod of Hatfield,with the other bishops, Theodore confirmed the Nicean Creed, fiveformer ecumenical councils and the generally accepted Church Fathers. They worked also on practical church unity, that is established: common date of Easter with other parts of Christian world, non-intervention ofbishops in other dioceses, canonical laws regulating the attitude of bishops towards monastic communities and the decrees against monophysismonks coming from Persia.

  3. Investigating the real situation of Greek solar water heating market

    2005-01-01

    Solar thermal applications have been acknowledged among the leading alternative solutions endeavouring to face the uncontrollable oil price variations, the gradual depletion of fossil fuel reserves and the chain environmental consequences caused by its excessive usage. Almost 30 years after the initial emergence of the commercial domestic solar water heating system (DSWHS) in the European market, the corresponding technology is qualified as quite mature. On top of this, the European Commission expects that 100,000,000 m 2 of solar collectors are to be installed in Europe by the year 2010 to facilitate durable and environment-friendly heat. In this context, the Greek DSWHSs market is highly developed worldwide, having a great experience in this major energy market segment. The present study is devoted to an extensive evaluation of the local DSWHSs market, including a discerning analysis of its time variation, taking seriously into account the corresponding annual replacement rate. Accordingly, the crucial techno-economic reasons, limiting the DSWHSs penetration in the local heat production market, are summarized and elaborated. Subsequently, the national policy measures - aiming to support the DSWHSs in the course of time - are cited, in comparison with those applied in other European countries. Next, the financial attractiveness of a DSWHS for Greek citizens is examined in the local socio-economic environment. The present work is integrated by reciting the prospects and mustering certain proposals that, if applied, could stimulate the local market. As a general comment, the outlook for penetration of new DSWHSs in the local market is rather grim, as the current techno-economic situation of solar heat cannot compete with oil and natural gas heat production, unless the remarkable social and environmental benefits of solar energy are seriously considered. Hence, the Greek State lacks stimulus to further DSWHSs installations, being strongly in support of the imported

    The goal of this paper is twofold: i) to investigate the carbon footprint of Greek households throughout the period 1995–2012, in order to identify the main socio-economic factors that affect GHG emissions, and ii) to evaluate the effectiveness of the implemented policies to tackle climate change. In this, a consumption-based emissions inventory approach is applied. The analysis is based on an environmentally-extended input-output model including direct CO_2 emissions from households, indirect CO_2 emissions from electricity consumption and indirect CO_2 emissions from energy used in the production of goods and services purchased by households, domestic or imported. Statistical analysis and appropriate regression models were developed in order to identify the main factors influencing the carbon footprint of Greek households. The results indicate that the observed trends during the period 1995–2008 can be attributed to the effect of high economic growth. This trend is partially counterbalanced by favorable weather conditions and the implementation of greenhouse mitigation policies and measures mainly in the supply side. Since 2008 the shrinking household income is the dominant driver. In addition, the effectiveness of energy conservation policies and measures in place is rather low, while the effect of imports is limited. - Highlights: • The factors influencing the carbon footprint of Greek households have been analyzed. • The analysis is based on consumption-based GHG inventories. • High economic growth resulted in carbon footprint increases during 1995–2008. • Carbon footprint reduction after 2008 is attributed to shrinking of household income. • Mitigation measures in power and manufacturing sectors reduced carbon footprint.

  5. HISTORICAL CONCEPTIONS OF A HEALTHY CITY: THE GREEK PARADIGM

    Full Text Available Today much attention is being given to the concept of a “healthy city”. However, the need for incoming paradigms is needed since this concept is still developing both as a term and as a real experience. The study of the historical experiences and examples can enrich the understanding of a healthy city’s historical background and can help in learning from the past. Especially the Greek paradigm appears of a particular importance as the idea of the creation of healthy cities seems to be central in the Hellenic (Greek culture, the first anthropocentric culture developed in Europe, which is perceived to form the base of the so called Western Civilization. The conceptions of a healthy city were supported by the Hellenic Mythology, Philosophy, Art and Science. The principles of the planning and design of healthy cities were expressed through various applications concerning the Greek cities and, especially, through the creation of specific settlements devoted to the restoration of health, such as Asklepieia. Asklepieia were centres of worship of the hero, divine physician and healing god, Asklepios and became the first health care centres in Europe. Asklepieia offered their healing environment and services for many centuries in the then Hellenic territory, from the pre-historic era and the War of Troy though out the Classical, Hellenistic and Roman times to the early-Byzantine times until the total prevalence of Christianity. In Asklepieia the restoration of health was understood as a result of positive interaction of physical, psychological, mental, spiritual, social, environmental, etc, factors.

    Mastitis occurs in numerous species. Antimicrobial agents are used for treatment of infectious mastitis in dairy cattle, other livestock, companion animals, and humans. Mastitis is an economically important disease of dairy cattle and most mastitis research has focused on epidemiology and control of bovine mastitis. Antibiotic treatment of clinical and subclinical mastitis in dairy cattle is an established component of mastitis control programs. Research on the treatment of clinical and subclinical mastitis in other dairy species such as sheep and goats has been less frequent, although the general principles of mastitis therapy in small ruminants are similar to those of dairy cattle. Research on treatment of clinical mastitis in humans is limited and as for other species empirical treatment of mastitis appears to be common. While antimicrobial susceptibility testing is recommended to direct treatment decisions in many clinical settings, the use of susceptibility testing for antibiotic selection for mastitis treatments of dairy cattle has been challenged in a number of publications. The principle objective of this review is to summarize the literature evaluating the question, "Does antimicrobial susceptibility predict treatment outcome for intramammary infections caused by common bacterial pathogens?" This review also addresses current issues related to antimicrobial use and treatment decisions for mastitis in dairy cattle. Information on treatment of mastitis in other species, including humans, is included although research appears to be limited. Issues related to study design, gaps in current knowledge and opportunities for future research are identified for bovine mastitis therapy.

  7. Microbiological Spoilage of Dairy Products

    Science.gov (United States)

    Ledenbach, Loralyn H.; Marshall, Robert T.

    The wide array of available dairy foods challenges the microbiologist, engineer, and technologist to find the best ways to prevent the entry of microorganisms, destroy those that do get in along with their enzymes, and prevent the growth and activities of those that escape processing treatments. Troublesome spoilage microorganisms include aerobic psychrotrophic Gram-negative bacteria, yeasts, molds, heterofermentative lactobacilli, and spore-forming bacteria. Psychrotrophic bacteria can produce large amounts of extracellular hydrolytic enzymes, and the extent of recontamination of pasteurized fluid milk products with these bacteria is a major determinant of their shelf life. Fungal spoilage of dairy foods is manifested by the presence of a wide variety of metabolic by-products, causing off-odors and flavors, in addition to visible changes in color or texture.

    Turko-Greek relations have been strained by a number of conflicting issues such as Cyprus, Continental Shelf, Territorial Waters, the Öcalan affair, and the S-300 Missiles crisis on Cyprus. Until the December 1999 Helsinki Summit, Greece was one of the strong opponents of Turkey's membership in the European Union (EU). However, at the Helsinki Summit of 1999, Greece dropped her negative position permitting Turkey to be declared by the EU as a candidate country. This shift in foreign policy ha...

    A series of 25 Greek coins from the 6th to 4th centuries BC was studied by PIXE for their trace element composition, with an aim to discover the origin of their silver ore. The procedure revealed a counterfeited coin, and then concentrated on distinguishing the coins minted from the ore of Laurion on the Attica peninsula and the coins minted from other sources. Linear discriminant analysis based on the impurities and alloying elements of copper, gold, lead and bismuth revealed that discrimination is indeed possible according to a single canonical variable.

  10. Assessment of the lower ESR dating range in Greek speleothems

    2001-01-01

    Pilot ESR dating studies on geologically young calcitic sinters were carried out, aiming at assessment of the lower ESR dating range in characteristic Greek speleoenvironments. Five stalactites were dated, coming from an ancient mining gallery, idle for the last 2,500 years, found on Siphnos island (Aegean). The calculated ages range between 1,7-2,0 ka. Medium to low measured external dose rates (aprox. 900 μGy/a) and very low measured radioelement concentration in samples are very usual in the Mediterranean environments. The study concludes that ESR dating of speleothems younger than two millenia is practically unattainable. Some geoarchaeological implications of the obtained ages are discussed. (author)

    2014-12-01

    Full Text Available Some years have passed since the publication of Adrados’ book History of the Graeco-Latin Fable, it is convenient to add some novelties. First of all, a mention must be added to books by Jedrkiewicz, van Dijk and also by Adrados. Then, a reference is needed also to Sumerian, Acadian and Egyptian fables which have left some motives in the greek Fable. In particular, are important some myths related to the creation of men and animals: their original nature must be preserved, if not bad consequences originate. That is the old wisdom of proverbs and fables, nature does nor change. Some omnipresent examples are presented.

    A study has been made of carbon-13 and oxygen-18 variations in Greek marbles from the ancient quarry localities of Naxos, Paros, Mount Hymettus, and Mount Pentelikon. Parian, Hymettian, and Pentelic marbles can be clearly distinguished by the isotopic relationships; Naxian marbles fall into two groups characterized by different oxygen-18/oxygen-16 ratios. Ten archeological samples were also analyzed; the isotopic data indicate that the "Theseion" is made of Pentelic marble and a block in the Treasury of Siphnos at Delphi is probably Parian marble.

    Full Text Available Review of: Vinzenz Brinkmann, Oliver Primavesi, Max Hollein, (eds, Circumlitio. The Polychromy of Antique and Medieval Sculpture. Liebighaus Skulpturensammlung, Frankfurt am Main, 2010. New scientific methods now being applied to the analysis of traces of pigments and gilding on ancient Greek and Roman marble statuary, and other marble artefacts, have the potential to revolutionise our understanding of the relationship between form and colour in antiquity. At present the enquiry is still in its infancy, but the papers delivered at a conference held in Frankfurt in 2008, reviewed here, provide a general introduction to the subject and to a wide range of work in progress.

  15. Uxoricide in pregnancy: ancient Greek domestic violence in evolutionary perspective.

    2013-10-24

    Previous studies of ancient Greek examples of uxoricide in pregnancy have concluded that the theme is used to suggest tyrannical abuse of power and that the violence is a product of the patriarchal nature of ancient society. This article uses evolutionary analyses of violence during pregnancy to argue that the themes of sexual jealousy and uncertainty over paternity are as crucial as the theme of power to an understanding of these examples and that the examples can be seen as typical instances of spousal abuse as it occurs in all types of society.

    The ancient Greek physicians have not failed in their studies to indicate the beneficial role of sexual activity in human health. They acknowledged that sex helps to maintain mental balance. Very interesting is their observation that sex may help mental patients to recover. Nevertheless they stressed emphatically that sex is beneficial only when there is a measure in it, so they believed that sexual abstinence or excessive sexual activity affect negatively the mental and physical health of man. Ancient Greek physicians reached this conclusion by empirical observation. They tried to justify the mental imbalance, as the potential physical problems, which probably will be listed today in the psychosomatic manifestations, of people with long-term sexual abstinence or hyperactivity, based on the theory of humors which was the main methodological tool of ancient Greek medicine. Their fundamental idea was that the four humors of the body (blood, phlegm, yellow and black bile) should be in balance. Therefore they believed that the loss and the exchange of bodily fluids during sex help body's humors to maintain their equilibrium which in turn will form the basis for the physical and mental health. Although in ancient medical texts the irrationality presented by people in the aforementioned conditions was not attributed in any of the major mental illnesses recognized in antiquity, as mania, melancholy and phrenitis, our belief is that their behavior is more suited to the characteristics of melancholy, while according to modern medicine it should be classified in the depressive disorders. We have come to this conclusion, because common characteristics of people who either did not have sexual life or was overactive, was sadness, lack of interest and hope, as well as paranoid thinking that can reach up to suicide. Regarding the psychosomatic problems, which could occur in these people, they were determined by the ancient Greek physicians in the following; continuous headaches

    2014-05-01

    Full Text Available The so-called Greek Financial Crisis, which has been the object of close attention in the German media since the end of 2009, has caused a public debate on who should be held responsible for the decline of crisis-hit Greece, the common currency and the Eurozone. The media’s enduring and controversial public discussion has lately been referred to as the Greek bashing. When the crisis had spread much further in 2012 and also other countries suffered from high debt, economic stagnation and unemployment, the news coverage became more moderate. This project report highlights the role of medial discourses of difference and solidarity during the crisis. Therefore, we rely on an exemplary data-set that does not only take the development of the German media’s tenor on the Greek Crisis into consideration, but also adds an international perspective in order to compare the medial treatment of different countries involved. The study methodologically focuses on the analysis of (metaphorical language and grammatical structures in the news coverage of the German daily newspaper BILD, the German magazine SPIEGEL as well as the international news magazines Economist (Great Britain and TIME (USA. Therefore, the interdisciplinary approach of Critical Discourse Analysis (CDA was used in order to produce insights into public discourses in sociopolitical contexts.

    Full Text Available Since 2008 economic crisis has dominated global economic policy discussions, no more so than in Greece. In Greece, the imposition of austerity policies has caused immense social and political upheaval. I suggest that policy thinking about the current Greek debt crisis requires a broader engagement with global civic virtue. Specifically, I present a case for revisiting the political thought of Seneca and Machiavelli. Both discuss the virtue of mercy and its role in good governance policy. I argue that policy solutions for the economic crisis facing Greece and Europe need to be informed by their thinking.
