BACKGROUND The laparoscopic treatment of rectal cancer is controversial. This study compared surgical outcomes after laparoscopic and open approaches for mid and low rectal cancers. METHODS Some 204 patients with mid and low rectal adenocarcinomas were allocated randomly to open (103) or laparoscopic (101) surgery. The surgical team was the same for both(More)
Small ruminant lentiviruses (SRLVs), including maedi-visna virus (MVV) of sheep and caprine arthritis-encephalitis virus (CAEV), are widespread, cause fatal diseases and are responsible for major production losses in sheep and goats. Seventy years after the legendary maedi-visna sheep epidemic in Iceland, which led to the first isolation of a SRLV and(More)
The aim of the present study is to highlight the advantages of real-time quantitative PCR intended to aid in the diagnosis and monitoring of canine leishmaniosis. Diagnosis of canine leishmaniosis is extremely challenging, especially in endemic areas, due to the diverse and non-specific clinical manifestations, and due to the high seroprevalence rate in(More)
The aim of this study was to investigate methods for detecting QTL in outbred commercial pig populations. Several QTL for back fat and growth rate, previously detected in experimental resource populations, were examined for segregation in 10 different populations. Two hundred trait-by-population-by-chromosome tests were performed, resulting in 20 tests(More)
An experimental F2 cross between Iberian and Landrace pig strains was performed to map quantitative trait loci (QTL) for diverse productive traits. Here we report results for meat quality traits from 369 F2 animals with records for pH 24 h postmortem (pH 24 h), muscle color Minolta measurements L* (lightness), a* (redness), and b* (yellowness), H* (hue(More)
The effect of interferon-beta in multiple sclerosis is modest and many patients do not respond to treatment. To date, no single biomarker reliably correlates with responsiveness to interferon-beta in multiple sclerosis. In the present study, genome-wide expression profiling was performed in peripheral blood mononuclear cells from 47 multiple sclerosis(More)
We have investigated the origin of swine breeds through the joint analysis of mitochondrial, microsatellite, and Y-chromosome polymorphisms in a sample of pigs and wild boars with a worldwide distribution. Genetic differentiation between pigs and wild boars was remarkably weak, likely as a consequence of a sustained gene flow between both populations. The(More)
The chicken insulin-like growth factor (IGF)1 and IGF2 genes have been partially sequenced in six individuals of each of two chicken strains of the Black Penedesenca breed (PN and MN). These two strains are genetically diverse for growth traits. Sequence alignment revealed the existence of three single nucleotide polymorphisms (SNP) (IGF1-SNP1, IGF2-SNP2,(More)
Blood samples from 153 dogs living in and around Barcelona were assayed for Leishmania infantum and Ehrlichia, Anaplasma, Rickettsia, Bartonella, Hepatozoon, Babesia and Theileria species by PCR amplification of DNA, and the amplicons obtained were sequenced. The prevalence of the infectious agents was L infantum (29.4 per cent), Ehrlichia and Anaplasma(More)
