BACKGROUND AND OBJECTIVE Japanese pulmonologists, experienced in treating patients with diffuse panbronchiolitis (DPB) prior to the 1980s, have uniformly observed that new incidences of DPB are now a rare event in Japan. However, there is no epidemiological data to support this observation. We examined epidemiological trends of the number of patients with DPB in a large company. DESIGN The co...
Epstein-Barr virus-positive diffuse large B-cell lymphoma of the elderly (EBV+ DLBCL-e) is a molecularly distinct variant of DLBCL, characterized by a monoclonal B-cell proliferation that occurs in patients >50 years of age without a history or clinicopathologic evidence of immunodeficiency. However, patients with EBV+ DLBCL younger than 50-years-old also exist in Western countries. We evaluate...
Three cases of diffuse panbronchiolitis (DPB) occurring in two Malaysian Chinese patients and one Malay patient are reported. They had similar clinical, radiological and physiological features which are characteristic of DPB. The diagnosis in one of the cases was confirmed histologically by transbronchial lung biopsy. These could be the first three cases identified in Malaysia.
We describe a simple test of the spatial uniformity of an ensemble of discrete events. Given an estimate for the point source luminosity function and an instrumental point spread function (PSF), a robust upper bound on the fractional point source contribution to a diffuse signal can be found. We verify with Monte Carlo tests that the statistic is superior to the two-point correlation function f...
Diffuse reflectance spectroscopy provides a noninvasive means to measure optical and physiological properties of tissues. To expand on these measurements, we have developed a handheld diffuse reflectance spectral imaging (DRSi) system capable of acquiring wide field hyperspectral images of tissue. The image acquisition time was approximately 50 seconds for a 50x50 pixel image. A transport model...
Analysis of deep-sea sediments presents a number of exceptional challenges. Generally, the amount of material available is small and has to be shared among investigators. Also, deep-sea sediment contains a diverse range of components from a variety of sources including lithogenous, biogenous and hydrogenous. Finally, large number of samples is frequently analysed making rapid analysis a necessi...
A novel palladium promoted Ag/Al2O3 catalyst (denoted Ag-Pd/Al2O3) has been developed for the selective catalytic reduction of NO by C3H6. The Ag-Pd/Al2O3 shows a higher NOx conversion than Ag/Al2O3, especially at the temperatures ranging from 300 to 450 ◦C. The addition of a small amount of Pd (0.01 wt.%) to Ag/Al2O3 is considered to be favorable for the partial oxidation of C3H6. In situ diff...
