Ethylenediaminetetraacetic acid (EDTA) is commonly used during the preparation of obstructed root canals that face a high risk of root perforation. Such perforations may be repaired with mineral trioxide aggregate (MTA). Due to EDTA's ability to chelate calcium ions, we hypothesized that EDTA may disrupt the hydration of MTA. Using scanning electron(More)
Opioid receptors are members of the guanine nucleotide binding protein (G protein)-coupled receptor family. Three types of opioid receptors have been cloned and characterized and are referred to as the delta, kappa and mu types. Analysis of receptor chimeras and site-directed mutant receptors has provided a great deal of information about functionally(More)
The sensitivity of mu and delta receptor binding to dithiothreitol and N-ethylmaleimide was examined to probe receptor structure and function. Binding to both receptor types was inhibited by dithiothreitol (IC50 values = 250 mM), suggesting the presence of inaccessible but critical disulfide linkages. mu receptor binding was inhibited with more rapid(More)
WHAT IS KNOWN AND OBJECTIVE The beneficial effects of docetaxel plus cisplatin-based induction chemotherapy for patients with unresectable, advanced head and neck cancer (HNC) have been documented in Western countries. However, the efficacy of such treatment has not been confirmed in Asian patients. We aimed to determine whether incorporation of(More)
OBJECTIVES To analyse the lung metastasis and possible factors influencing lung metastasis in alveolar soft part sarcoma (ASPS) patients. METHODS The medical records of 64 consecutive ASPS patients were reviewed to analyse their treatments, features of lung metastasis, and possible factors influencing lung metastasis. RESULTS Thirty-six females and 28(More)
We study charge transport in a monolayer MoS2 nanoflake over a wide range of carrier density, temperature and electric bias. We find that the transport is best described by a percolating picture in which the disorder breaks translational invariance, breaking the system up into a series of puddles, rather than previous pictures in which the disorder is(More)
BACKGROUND Haemangioma of the adult larynx is an uncommon, benign lesion. The optimal surgical method of treating these lesions is controversial because only very limited case series are available. This paper reports the results of transoral robotic resection of a supraglottic haemangioma in an adult and reviews the literature. METHODS AND RESULTS A(More)
The proto-oncogene c-fos is an immediate-early gene that becomes activated by a wide variety of extracellular stimuli. Since many studies regarding regulation of c-fos are conducted in vivo using rats, or with rat cell lines, we have cloned the rat c-fos gene in order to verify that the same regulatory elements that have been characterized in the human and(More)
Centromere proteins (CENPs) are required for the attachment of microtubules to chromosomes. However, their structure and mechanism of action are not well understood, especially in mammalian meiosis. The present study was conducted to examine (i). whether a human nuclear centromere autoantibody can be used to localize the CENPs in pig oocytes and (ii). the(More)
OBJECTIVE To investigate the effects of folic acid combined with vitamin B12 on deep vein thrombosis (DVT) in patients with homocysteine cerebral infarction. PATIENTS AND METHODS 90 patients with homocysteine cerebral infarction with DVT that were admitted to our hospital from January to July 2015 were selected as study subjects. They were divided into 2(More)
