A piperidinyl chlorotriazine (PCT) derivative, used as a plastic UV-stabilizer, caused an outbreak of occupational asthma. We verified, in BALB/c mice, the sensitizing potential of PCT in comparison to a known respiratory sensitizer (toluene diisocyanate [TDI]) and a known dermal sensitizer (oxazolone), using three different methods in order to evaluate the validity of current models of sensiti...
Objectives. Procalcitonin is a propeptide of calcitonin and has been increasingly used as a biomarker of infection. The aim of this study was to evaluate correlation of serum C-reactive protein (CRP) and procalcitonin (PCT) levels of kidney transplant patients hospitalized due to infection. Methods. There were 121 patients who had kidney transplant in our center between September 2012 and Febru...
OBJECTIVE Blood-brain barrier (BBB) permeability has been proposed as a predictor of hemorrhagic transformation (HT) after tissue plasminogen activator (tPA) administration; however, the reliability of perfusion computed tomography (PCT) permeability imaging for predicting HT is uncertain. We aimed to determine the performance of high-permeability region size on PCT (HPrs-PCT) in predicting HT ...
PURPOSE Procalcitonin (PCT) and C-reactive protein (CRP) are well known inflammatory markers. This study was designed to determine whether PCT and CRP are useful as early diagnostic markers for bacteremia in cancer patients with febrile neutropenia (FN) in the emergency department (ED). MATERIALS AND METHODS In this retrospective study, 286 episodes of FN in the ED were consecutively included...
PURPOSE We investigated the correlation between 24-hour IOP in the habitual (sitting during day and supine during night) position (H24h-IOP) and IOP after a postural-change test (PCT-IOP) and a water-drinking test (WDT-IOP). We also investigated ocular and systemic factors related with them in patients with normal tension glaucoma (NTG). METHODS Japanese NTG patients underwent H24h-IOP, PCT-I...
We have recently demonstrated that although the osmotic water permeability (P(f)) of neonatal proximal tubules is higher than that of adult tubules, the P(f) of brush-border and basolateral membrane vesicles from neonatal rabbits is lower than that of adults. The present study examined developmental changes in the water transport characteristics of proximal convoluted tubules (PCTs) in neonatal...
INTRODUCTION Porphyria cutanea tarda (PCT) is the most common type of porphyria. The strong association between PCT and hepatitis C virus (HCV) infection is well established. Although antiviral treatment of chronic hepatitis C may improve PCT in some cases, de novo onset of PCT has been observed in patients under- going peginterferon/ribavirin treatment. We present a rare case of a genotype 3 H...
The purposes of this study were to optimize a proton computed tomography system (pCT) for proton range verification and to confirm the pCT image reconstruction algorithm based on projection images generated with optimized parameters. For this purpose, we developed a new pCT scanner using the Geometry and Tracking (GEANT) 4.9.6 simulation toolkit. GEANT4 simulations were performed to optimize th...
BACKGROUND Fever is a common symptom in the emergency department(ED). Fever can be caused by bacterial infections, which are treated with antibiotics. Often, bacterial infections cannot be ruled out in the ED using standard diagnostics, and empiric antibiotic treatment is started. Procalcitonin(PCT) is a biomarker for bacterial infections, but its role in an undifferentiated ED population remai...
Ischemic stroke results from occlusion of a cerebral artery, and it is the leading cause of disability and the fifth leading cause of death in the United States. Cerebral artery occlusion results in irreversible death of a component of cerebral tissue, which is referred to as the core infarction. There is an additional component of brain tissue that is ischemic, but viable, which is commonly re...
