The wheat (Triticum aestivum) and rye (Secale cereale) beta-D-glucosidases hydrolyze hydroxamic acid-glucose conjugates, exist as different types of isozyme, and function as oligomers. In this study, three cDNAs encoding beta-D-glucosidases (TaGlu1a, TaGlu1b, and TaGlu1c) were isolated from young wheat shoots. Although the TaGlu1s share very high sequence(More)
OBJECTIVE To evaluate the efficacy of percutaneous administration of iohexol into the popliteal lymph node as a non-invasive technique for thoracic duct lymphangiography in dogs. STUDY DESIGN Experimental study and clinical report. ANIMALS Normal adult dogs (n=4) and 1 dog with recurrent chylothorax. METHODS For the experimental study, 4 dogs (weight,(More)
The present report describes an enzyme-linked immunosorbent assay for bovine apolipoprotein (apo) A-IV. This assay was applied to the determination of its concentration and distribution in sera from cattle. The distribution of apoA-IV in lipoprotein fractions separated by ultracentrifugation was mostly recovered in the non-lipoprotein fractions (d>1.21(More)
The β-D-glucosidases from wheat (Triticum aestivum) and rye (Secale cereale) hydrolyze benzoxazinone-glucose conjugates. Although wheat and rye glucosidases have high sequence identity, they have different substrate preferences; the wheat enzyme favors DIMBOA-Glc (2-O-β-D-glucopyranosyl-4-hydroxy-7-methoxy-1,4-benzoxazin-3-one) over DIBOA-Glc(More)
Three canine gastrointestinal stromal tumors (GISTs) were examined. Histopathologically, the tumor mass in the jejunum (Case 1) consisted of the proliferation of epithelioid cells with abundant eosinophilic or vacuolated cytoplasm. Gangliocyte-like or multinucleated giant cells were scattered. The tumor cells exhibited neural natures mimicking human(More)
Many organophosphorus (OP) compounds are of the thiono form and in insects or animals are converted by microsomal mixed function oxidases (MFO) into the oxon forms which inhibit acetylcholinesterase (AChE) and give toxic activity. However, certain S-alkyl phosphorothiolates (RS-P(O) <) such as methamidophos, profenophos and prothiophos oxon are strongly(More)
This paper describes a nephroblastoma with transcoelomic metastasis in a three-year-old Japanese black bull. At necropsy, a huge, oval neoplastic mass containing the residual right kidney was found. Moreover, severe transcoelomic metastasis occurred throughout the abdominal and thoracic cavities. Histologically, the mass was mainly composed of sheets,(More)
In this paper, we propose a visual assistance system that shows the scene behind a vehicle to its driver in the form of a virtual mirror by utilizing a surveillance camera. The virtual mirror will be displayed on a windshield display as if it were floating in the air in front of the vehicle. The driver entering an intersection can confirm the safety around(More)
Glutathione transferases (GSTs) play an important role in the detoxification of insecticides, and as such, they are a key contributor to enhanced resistance to insecticides. In the housefly (Musca domestica), two epsilon-class GSTs (MdGST6A and MdGST6B) that share high sequence homology have been identified, which are believed to be involved in resistance(More)
Histopathological and enzyme histochemical observations were performed on mast cells in pulmonary arterial lesion of Dirofilaria immitis in dogs. The results showed that chymase- and tryptase-positive mast cells were diffusely present in the lesions, especially in the adventitia and proliferated intima. At 2 weeks after surgical worm transplantation, mast(More)
