This work investigated the size distribution of the droplet nuclei and coughed droplets by test subjects. The size distributions of droplet nuclei coughed by test subjects were determined with an aerodynamic particle sizer (APS) and scanning mobility particle sizer (SMPS) system (system 1). Coughed droplets were only sampled with the APS system (system 2).(More)
Recently, Wang introduced a novel (2, n) region incrementing visual cryptographic scheme (RIVCS), which can gradually reconstruct secrets in a single image with multiple security levels. In RIVCS, the secret image is subdivided into multiple regions in such a way that any t shadow images, where 2 ≤ t ≤ n, can be used to reveal the (t − 1)th region. However,(More)
Rutin has been shown to possess beneficial health effects, including hepatoprotection. However, to date, it has not been demonstrated to have a hepatoprotective effect against cholestatic liver injury. This is the first report to show a protective effect of rutin on cholestatic liver injury. Cholestasis was produced by bile duct ligation (BDL) in male(More)
BACKGROUND Adipokines, including adipocyte fatty acid-binding protein (A-FABP), have been demonstrated to be involved in the pathogenesis of atherosclerosis. In the present study, we investigated the association of circulating A-FABP level with severity of myocardial perfusion abnormalities analyzed by Tl-201 dipyridamole single-photon emission computed(More)
To evaluate the usefulness of an approach through the radial artery distal to the arteriovenous anastomosis for salvaging nonmaturing radiocephalic arteriovenous fistulas. Procedures that fulfilled the following criteria were retrospectively reviewed: (1) autogenous radiocephalic fistulas, (2) fistulas less than 3 months old, (3) distal radial artery(More)
AIMS There is an ongoing discussion on whether serum uric acid (SUA) predicts ischemic heart disease (IHD) independently of other metabolic factors, which, if confirmed, would signify a role for uric acid in the pathogenesis of cardiovascular disease. We investigated whether such a relation exists for ethnic Chinese with low CVD risk. METHODS AND RESULTS(More)
Plasma levels of asymmetrical dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide production, correlate with endothelial dysfunction and the development of cardiovascular events in patients with uremia. It is not known whether endothelial dysfunction contributes to the dysfunction of arteriovenous fistulas (AVFs) in hemodialysis patients. Here,(More)
A novel and interesting application of RFID was a banknote attached a tag to determine the authenticity of money and to stop counterfeits. At Financial Cryptography 2003, Juels and Pappu firstly proposed a practical RFID banknote protection scheme (RBPS) by using the optical and the electrical (RFID) contacts. RFID-enabled notes can be tracked by the legal(More)
Airway fire resulting from ignition of the endotracheal tube (ETT) caused by electrocautery during tracheostomy is a severe and possibly fatal event, and should be avoided. An 88-year-old male because of respiratory failure received elective tracheostomy for ventilatory support on which prolonged dependence was anticipated. Unfortunately, flame was noted to(More)
