The indolizidine alkaloid swainsonine (SW) has been reported to impair placentae and ultimately cause abortion in pregnant goats. Up to now, however, the precise effects of SW on goat trophoblast cells (GTCs) are still unclear. In this study, the cytotoxicity effects of SW on GTCs were detected and evaluated by MTT assay, AO/EB double staining, DNA fragmentation assay and flow cytometry analysi...

BACKGROUND Spinal walking (SW) is described as the acquisition of an involuntary motor function in paraplegic dogs and cats without pain perception affected by a thoracolumbar lesion. Whereas spinal locomotion is well described in cats that underwent training trials after experimental spinal cord resection, less consistent information is available for dogs. HYPOTHESIS Paraplegic dogs affected...

BACKGROUND/AIMS In a questionnaire survey, we identified 36 (9%) of 417 Parkinson's disease (PD) patients with sleepwalking (SW); 72% of them also had a history of REM sleep behaviour disorder (RBD). We aimed to assess the clinical and polysomnographic characteristics of SW in PD and to compare them to patients with PD with and without a history of RBD. METHODS We performed video-polysomnogra...

Steelhead rainbow trout acclimated to either freshwater (FW) or seawater (SW) were exposed to high environmental ammonia (HEA, 1000 μmol l(-1) NH(4)HCO(3), pH 7.8-8.0) for 24 h. SW trout restored ammonia excretion more rapidly (3-6 h versus 9-12 h in FW), despite higher production rates and lower plasma pH. Plasma total ammonia levels stabilized at comparable levels below the external HEA conce...

We have previously demonstrated that low-energy extracorporeal cardiac shock wave (SW) therapy improves myocardial ischemia through enhanced myocardial angiogenesis in a porcine model of chronic myocardial ischemia and in patients with refractory angina pectoris. However, the detailed molecular mechanisms for the SW-induced angiogenesis remain unclear. In this study, we thus examined the effect...

The construction of bridges and other structures across the river will affect flood discharge capacity local water potential river.Based on navier-Stokes equation MIKE21FM hydrodynamic module, this paper carries out two-dimensional numerical simulation part Shixi River. By optimizing grid near piers to reduce difference brought by terrain generalized real river, it simulates analyzes length cur...

BACKGROUND In the late 1990s, triple reassortant H3N2 influenza A viruses emerged and spread widely in the US swine population. We have shown previously that an isolate representative of this virus-lineage, A/Swine/Minnesota/593/99 (Sw/MN), exhibits phenotypic differences compared to a wholly human-lineage H3N2 virus isolated during the same time period, A/Swine/Ontario/00130/97 (Sw/ONT). Speci...

INTRODUCTION Impaired coordination between breathing and swallowing (breathing-swallowing discoordination) may be a significant risk factor for the exacerbation of chronic obstructive pulmonary disease (COPD). We examined breathing-swallowing discoordination in patients with COPD using a non-invasive and quantitative technique and determined its association with COPD exacerbation. METHODS We ...
