A cDNA of alpha alpha-trehalase (EC 3.2.1.28) from a cDNA library of male bean-shaped accessory gland of the mealworm beetle, Tenebrio molitor, has been isolated by the homology screening approach. Sequence analysis of the cDNA (1830 bp) revealed that the cDNA encoded a protein of 555 amino acids with a calculated M(r) of 64457. The deduced amino acid(More)
The mechanistic dissociation of 'tumor starvation' versus 'vascular normalization' following anti-angiogenic therapy is a subject of intense controversy in the field of experimental research. In addition, accurately evaluating changes of the tumor microenvironment after anti-angiogenic therapy is important for optimizing(More)
We have recently characterized IQI/Jic mice as a model for Sjogren's syndrome (SS), a chronic autoimmune disease in humans. In SS, local lymphocytic infiltrations into salivary and lacrimal glands frequently develop to the involvement of systemic exocrine and nonexocrine organs, and the mechanism for progression of this disease remains obscure. Herein, we(More)
An early identification of the tumor response to sorafenib treatment is indispensable for selecting optimal personalized treatment strategies. However, at present, no reliable predictors are clinically available. 18F‐fluorothymidine (18F‐FLT) positron emission tomography (PET) is used to assess tumor proliferation, since the FLT uptake level reflects(More)
We have recently characterized IQI/Jic mice as a model for Sjögren’s syndrome (SS), a chronic autoimmune disease in humans. In SS, local lymphocytic infiltrations into salivary and lacrimal glands frequently develop to the involvement of systemic exocrine and nonexocrine organs, and the mechanism for progression of this disease remains obscure. Herein, we(More)
Abdominal ultrasonography is one of the most common diagnostic imaging modalities used for dogs with suspected insulinoma; however, pancreatic masses are clearly identified in fewer than half of affected dogs and benign pancreatic nodules can be difficult to differentiate from malignant ones. The purpose of this prospective study was to describe(More)
Subpopulations of infiltrating lymphocytes, professional antigen-presenting cells (APCs), and Th1/Th2 cytokines that could initiate an autoimmune sialodacryoadenitis were studied in the IQI/Jic mouse model of primary Sjögren's syndrome. Although lymphocytic infiltrations were first seen in submandibular glands (SMGs) of females and in lacrimal glands (LGs)(More)
Minute virus of canines (MVC), also known as canine parvovirus type 1, was initially believed to be a nonpathogenic agent, since it was first isolated from canine fecal specimens in the late 1960s. However, subsequent pathological as well as epidemiological studies suggested that MVC is a pathogen of neonatal puppies and is widely distributed among domestic(More)
Ultrasound targeted microbubble destruction has succeeded in delivering drugs and genes. This study was designed to explore characteristics of ultrasound targeted microbubble destruction using short-pulsed diagnostic ultrasound. Canine thyroid adenocarcinoma cells were exposed to short-pulsed diagnostic ultrasound in the presence of(More)
