| strong signatures of selection in the domestic pig genome. | domestication of wild boar (sus scrofa) and subsequent selection have resulted in dramatic phenotypic changes in domestic pigs for a number of traits, including behavior, body composition, reproduction, and coat color. here we have used whole-genome resequencing to reveal some of the loci that underlie phenotypic evolution in european domestic pigs. selective sweep analyses revealed strong signatures of selection at three loci harboring quantitative trait loci that explain a considerable part of ... | 2012 | 23151514 |
| african swine fever virus eradication in africa. | african swine fever was reported in domestic pigs in 26 african countries during the period 2009-2011. the virus exists in an ancient sylvatic cycle between warthogs (phacochoerus africanus) and argasid ticks of the ornithodoros moubata complex in many of the countries reporting outbreaks and in two further countries in the region. eradication of the virus from the countries in eastern and southern africa where the classic sylvatic cycle occurs is clearly not an option. however, the virus has be ... | 2013 | 23142552 |
| review of the sylvatic cycle of african swine fever in sub-saharan africa and the indian ocean. | african swine fever (asf) is a major limiting factor for pig production in most of the countries in sub-saharan africa and the indian ocean. in the absence of vaccine, a good understanding of the ecology and epidemiology of the disease is fundamental to implement effective control measures. in selected countries of southern and east africa, the association between ornithodoros moubata ticks and warthogs has been described in detail in the literature. however, for many other countries in the regi ... | 2013 | 23142551 |
| pathogenesis of african swine fever in domestic pigs and european wild boar. | african swine fever (asf) is among the most important viral diseases that can affect domestic and feral pigs. both clinical signs and pathomorphological changes vary considerably depending on strain virulence and host factors. acute infections with highly virulent virus strains lead to a clinical course that resembles a viral haemorrhagic fever that is characterized by pronounced depletion of lymphoid tissues, apoptosis of lymphocyte subsets, and impairment of haemostasis and immune functions. i ... | 2013 | 23137735 |
| african swine fever virus serodiagnosis: a general review with a focus on the analyses of african serum samples. | african swine fever (asf) is an infectious disease that causes heavy mortality in domestic pigs. at present there is no vaccine against asf, and eradication in countries where the disease is endemic is based only on competent diagnosis programs and the sacrifice of infected animals. due to the presence of natural attenuated strains, certain infection conditions may result in reduced mortality. in these situations, the disease can be diagnosed by detection of specific antibodies. the use of class ... | 2013 | 23131491 |
| biological heart rate reduction through genetic suppression of gα(s) protein in the sinoatrial node. | elevated heart rate represents an independent risk factor for cardiovascular outcome in patients with heart disease. in the sinoatrial node, rate increase is mediated by β(1) adrenoceptor mediated activation of the gα(s) pathway. we hypothesized that genetic inactivation of the stimulatory gα(s) protein in the sinoatrial node would provide sinus rate control and would prevent inappropriate heart rate acceleration during β-adrenergic activation. | 2012 | 23130123 |
