Radiologic findings of anthracofibrosis

Abstract

(Figs. 2, 3) , 종괴가 4예 (33 % ) (Fig. 4) , 기강 (67 % ) (Fig. 1, Fig. 4 Purpose: To evaluate the CT findings of bronchial anthracofibrosis. Materials and Methods: Fourteen patients with bronchoscopically confirmed anthracofibrosis were involved in this study. CT findings (n=12) were retrospectively analysed;the pattern, distribution and extent of bronchial and parenchymal abnormalities and additional findings such as mediastinal lymphadenopathy and pleural effusion were assessed. Age, sex, and oècupational and disease history were also reviewed.Results: Patients were aged between 63 and 95 (mean, 7 1.3)years, and ten were female . Only one patient had an occupational history, but four had a history of pulmonary tuberculosis. Frequent radiologic findings were bronchial wall thickening(n=6), atelectasis(n=8), mediastinal lymphadenopathy(n=7) and mass(n=4). Other accompanying findings were bronchial wall calcification(n=3), consolidation(n=2) and pleural effusion(n=2). Right upper (n=7) and right middle lobe(n=7) were the most commonly involved sites, and multifocal involvement(n=7) was frequent.Conclusion: Bronchial wall thickening, atelectasis and mediastinal lymphadenopathy were characteristic CT findings of anthracofibrosis. When such findings are noted in older or aged female patients, anthracofibrosis should be included in the differential diagnosis.

Noninvasive Continuous Monitoring of Physiological Glucose Using a Monosaccharide-Sensing Contact Lens

“…The latter two issues will be discussed throughout much of this paper. For the identification of suitable transduction elements, boronic acid has been known to have a high affinity for diolcontaining compounds, such as carbo-hydrates, [20][21][22] in which the strong complexation has been used for the construction of carbohydrate sensors, [23][24][25][26][27][28][29][30] transporters, 31 and chromatographic materials. 32 Naturally, boronic acid compounds have been used for the synthesis of glucose sensors.…”

Two-dimensional calculation of spatial distribution of neutral atoms for a planar inductively coupled oxygen discharge

“…In the case of monatomic gas, the feed neutral gas itself experiences rapid depletion (ion-pumping effect). Because this removal rate is much faster than the rate of thermal neutral diffusion from the walls or gas injection sources, the neutral density in the central portion of the plasma can be significantly reduced [4,11]. The neutral atom in an oxygen discharge has a behavior different from that in the monatomic feed gas case like argon.…”

Characteristics of temporal evolution of particle density and electron temperature in helicon discharge

“…However, it seems that they are still insufficient to provide direct and precise guidance on the design of parameters like the pulse width and duty cycle when employed practically. Almost all of the previous theoretical research has employed global models [8][9][10][11], belonging to the zero-dimension category. In these models, Lieberman [9] and Yoon [10] used a given absorption power, which was in accordance with the experimental results.…”

Cho [11] developed it to a self-consistent model by incorporating the power absorption calculation based on the solutions of a balance model.…”

“…The boundary of computational domain is extended to the entity wall by controlling the surface chemical reactions and the flux of particles deduced by the sheath theory at the wall. Most previous helicon discharge models, on the other hand, take the pre-sheath as the boundary in the calculations, as in references [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], in which case the parameters of the plasma sheath cannot be obtained. The densities of the species and the electron energy are described by the drift diffusion equations, as in [8,9].…”
