Layered electrophotographic photoconductors using chloroindium chlorophthalocyanine have been investigated. An evaporated film of has a broad and strong light absorption band in the visible to near-infrared region its crystal structure is very stable. The photoconductor as carrier generation layer polyvinylcarbazole transport highly sensitive wide spectral (500–900 nm) without any special treatment during preparation. typical value sensitivity 2.5 cm2/μJ at 800–900 nm, so that this most...

Abstract Background Sarcopenia has been identified as a potential negative prognostic factor in cancer patients. In this study, our objective was to investigate the relationship between assessment method for sarcopenia using masseter muscle volume measured on computed tomography (CT) images and life expectancy of patients with oral cancer. We also developed learning model deep automatically extract investigated its association Methods To develop volume, we used manually extracted data from...

Previous reports have suggested that right ventricular apical pacing may lead to cardiac dysfunction. Septal is thought be superior in the prevention of dyssynchrony, however, there been no on contribution septal improving clinical outcome.We retrospectively evaluated factors associated with events patients pacing.The study population consisted 256 consecutive newly implanted permanent pacemakers and followed-up for 29 ± 18 months. Cardiac events, consisting death or heart failure requiring...

Amyotrophic lateral sclerosis (ALS) is a progressive disease affecting upper and lower motor neurons. Feeding disorders are observed in patients with ALS. The mastication movements their systemic effects ALS feeding remain unclear. Currently, there no effective treatment for However, it has been suggested that treating improving nutritional status may prolong the lives of Therefore, this study elucidates future therapeutic agents. We conducted temporal observation behavior using an...

Abstract We develop a unified derivation of asymmetric pure strategy equilibria and their optimality in the canonical common interest voting model Austen-Smith Banks (Am Polit Sci Rev 90(1):34–45, 1996). also study relationship between most efficient equilibria, which have remarkably simple intuitive structure, symmetric mixed equilibrium that has been commonly studied literature. In particular, while efficiency under unanimity rule is known to be decreasing number voters, does not depend on...

Abstract Background Although cervical lymph node metastasis is an important prognostic factor for oral cancer, occult metastases remain undetected even by diagnostic imaging. We developed a learning model to predict in resected specimens of tongue cancer classifying the level immunohistochemical (IHC) staining angiogenesis‐ and lymphangiogenesis‐related proteins using multilayer perceptron neural network (MNN). Methods obtained dataset 76 patients with squamous cell carcinoma who had...

Acute myocardial infarction (AMI) is associated with left ventricular remodelling (LVR), which leads to progressive heart failure. Platelets play a pivotal role in promoting systemic and cardiac inflammatory responses during the complex process of wound healing or repair following AMI. This study aimed investigate impact platelet reactivity immediately after primary percutaneous coronary intervention (PCI) on LVR AMI patients ST-segment (STEMI) non-ST-segment elevation (NSTEMI).

To evaluate the stabilizing effects of an antilipemic agent, bezafibrate, on coronary plaques, we carried out a prospective angioscopic and angiographic open trial. From April 1997 to December 1998, 24 patients underwent angioscopy plaques in non-targeted vessels during interventions then again 6 months later. The were divided into control (10 patients, 14 plaques) bezafibrate (14 21 groups. Oral administration (400 mg/day) was started immediately after intervention continued for months....

Interactions between virulence factors of pathogens and host responses play an important role in the establishment infection by microbes. We focused on interactions Cryptococcus neoformans proteins heparin, which is abundant epithelial cells. Surface were extracted analyzed. Fractions from anion-exchange column chromatography interacted with heparin surface plasmon resonance analyses. Heparin-binding purified then separated gel electrophoresis; identified as transaldolase,...

Abstract Trichosporon asahii is a pathogenic yeast that cause trichosporonosis. T. exhibits several colony morphologies, such as white (W)‐ or off‐white (O)‐type, which may affect virulence. In this study, we compared the expression pattern of heparin‐binding proteins in various morphologies and identified protein . Surface plasmon resonance analysis revealed cell surface molecules attached more strongly to heparin W‐ than O‐type cells. We purified expressed W‐type cells using...
