We present two quantum calculations of the infrared spectrum of protonated methane (CH5+) using full-dimensional, ab initio-based potential energy and dipole moment surfaces. The calculated spectra compare well with a low-resolution experimental spectrum except below 1000 cm(-1), where the experimental spectrum shows no absorption. The present calculations find substantial absorption features below 1000 cm(-1), in qualitative agreement with earlier classical calculations of the spectrum. The major spectral bands are analyzed in terms of the molecular motions. Of particular interest is an intense feature at 200 cm(-1), which is due to an isomerization mode that connects two equivalent minima. Very recent high-resolution jet-cooled spectra in the CH stretch region (2825 to 3050 cm(-1)) are also reported, and assignments of the band origins are made, based on the present quantum calculations. 相似文献

A 13-year-old neutered female Labrador retriever had inspiratory dyspnea secondary to bilateral laryngeal paralysis. Radiographically, there was pectus excavatum with a mediastinal shift to the right. Arytenoid lateralization was performed, relieving the upper respiratory obstruction, and the sternal deformity also resolved. Chronic upper respiratory obstruction should be considered in dogs with pectus excavatum. Furthermore, correction of upper respiratory obstruction has the potential to result in resolution of pectus excavatum. 相似文献

In dogs with a congenital portosystemic shunt (CPSS), the outcome after CPSS attenuation is difficult to predict but is most likely related to hepatic and vascular proliferation that follows the attenuation. The aim of this study was to evaluate the prognostic value of shunt localization (extrahepatic vs. intrahepatic), plasma albumin concentration and hepatic mRNA expression of 19 genes involved in hepatic and vascular growth. The study population consisted of 48 dogs that were referred for surgical ligation of a single intrahepatic or extrahepatic CPSS. Gene expression was measured in intraoperatively sampled hepatic tissue with quantitative real-time PCR. Albumin, methionine adenosyltransferase 2α (MAT2α) and HGF activator (HGFac) were positively associated with complete recovery after CPSS attenuation using multivariate statistical analyses. Individual outcome could be correctly predicted in 83% of dogs using albumin, MAT2α and HGFac as high or low values compared to cut-off values of 19.5 g/L, 0.457 and 0.974, respectively. These variables predicted outcome after CPSS ligation better than shunt localization or albumin alone. Other evaluated gene products were not correlated with outcome. 相似文献

A 10-year-old intact male Golden Retriever was presented to The Ohio State University Veterinary Medical Center for acute, non-painful facial swelling of the right mandibular region. On physical examination, the right mandibular swelling was found to represent marked lymphadenopathy of the submandibular lymph node. At this time, marked lymphadenopathy of the prescapular and popliteal lymph nodes was also appreciated. The CBC showed a moderate leukocytosis (38.4 × 109 cells/L, reference interval [RI] 4.8-13.9 × 109 cells/L) characterized by a moderate lymphocytosis (28.4 × 109 cells/L, RI 1.0-4.6 × 109 cells/L). Evaluation of peripheral blood and enlarged prescapular and popliteal lymph nodes revealed two morphologically different populations of homogeneous lymphocytes, with the lymphocyte population in the lymph nodes being distinct from that in the blood smear. Flow cytometry of peripheral blood revealed CD45-, CD5+, CD4-, CD8-, variably CD21+ neoplastic lymphocytes compatible with T-zone lymphocytes due to the absence of CD45 expression. Flow cytometry of the lymph node aspirate indicated a distinct population of CD21+ lymphocytes consistent with a B-cell phenotype along with a smaller proportion of the T-zone lymphocytes observed in the blood confirming the presence of two distinct populations of neoplastic lymphocytes, one involving T cells, and the other involving B cells. 相似文献
