molecular detection of hepatitis e virus in german domestic pigs.in industrial countries, hepatitis e virus (hev) transmission to humans is predominantly assumed to be a zoonotic infection. recently, it has been demonstrated that about 50% of domestic pigs in germany carry hev-specific antibodies. however, further investigations concerning the distribution of hev in different age groups of german domestic pigs, phylogenetic analyses and the viral load in the porcine liver are still pending. liver samples of all age groups from herds in a pig-dense region in n ...201323367665
hysteresis in di independent mechanisms in threshold for transition between 1:1 and 2:2 rhythms in pigs.previous studies have shown hysteresis in transition from 1:1 to 2:2 rhythms in action potential durations (apd) during decreasing and increasing cycle length pacing. as cycle lengths were constant, when alternans of apd occurred, so did of preceding diastolic intervals (dis), which engaged the restitution mechanism, i.e. dependence of apd on preceding di, making it impossible to determine whether the hysteresis originates from the di independent or dependent mechanism. by using pacing with expl ...201223365980
computed tomography-based diagnosis of diffuse compensatory enlargement of coronary arteries using scaling power laws.glagov's positive remodelling in the early stages of coronary atherosclerosis often results in plaque rupture and acute events. because positive remodelling is generally diffused along the epicardial coronary arterial tree, it is difficult to diagnose non-invasively. hence, the objective of the study is to assess the use of scaling power law for the diagnosis of positive remodelling of coronary arteries based on computed tomography (ct) images. epicardial coronary arterial trees were reconstruct ...201323365197
fluid resuscitation guided by sublingual partial pressure of carbon dioxide during hemorrhagic shock in a porcine model.to avoid aggressive fluid resuscitation during hemorrhagic shock, fluid resuscitation is best guided by a specific measurement of tissue perfusion. we investigated whether fluid resuscitation guided by sublingual pco2 would reduce the amount of resuscitation fluid without compromising the outcomes of hemorrhagic shock. ten male domestic pigs weighing between 34 and 37 kg were used. forty-five percent of estimated blood volume was removed during an interval of 1 h. the animals were then randomize ...201323364438
high-density dependence but low impact on selected reproduction parameters of brucella suis biovar 2 in wild boar hunting estates from south-western spain.porcine brucellosis is a disease caused by brucella suis, which is characterized by reproductive disorders in pigs. the number of cases of swine brucellosis has risen in many european countries, likely because of the presence of a wild reservoir of b. suis in wild boar. this study aimed at evaluating factors that may influence the probability of infection with brucella spp. in wild boar and at assessing the impact of a previous contact with brucella spp. on reproductive parameters of wild boar. ...201423347330
research resource: the endometrium database resource (edr).in order to understand the biology of the endometrium and potentially develop new diagnostic tools and treatments for endometrial diseases, the highly orchestrated gene expression/regulation that occurs within the uterus must first be understood. even though a wealth of information on endometrial gene expression/regulation is available, this information is scattered across several different resources in formats that can be difficult for the average bench scientist to query, integrate, and utiliz ...201323340253
