BACKGROUND Progressive massive fibrosis (PMF) is the severe form of coal workers' pneumoconiosis (CWP). Clinical observations have suggested that the components of PMF are inhomogenous. There may be a significant diversity in the magnitude of pulmonary impairment for miners with PMF. This study is intended to investigate the relationship between radiological categories of PMF and pulmonary impa...

this study is aimed to identify sources of particulate matter with mean aerodynamic diameterbelow 10 μm (pm10) present in the atmosphere of the metropolitan area of mexico city (mamc), usingsamples obtained from january 1st to june 30th, 2009, analyzed with x-ray spectrometric techniques.minivol samplers were used to collect samples on polycarbonate filters in three sites (north, center, andsou...

Sampling from a probability mass function (PMF) has many applications in modern computing. This paper presents a novel lossy compression method intended for large (O(10)) dense PMFs that speeds up the sampling process and guarantees high fidelity sampling. This compression method closely approximates an input PMF P with another PMF Q that is easy to store and sample from. All samples are drawn ...

Plastic mulching is an important technology in agricultural production both in China and the rest of the world. In spite of its benefit of increasing crop yields, the booming expansion of the plastic mulching area has been changing the landscape patterns and affecting the environment. Accurate and effective mapping of Plastic-Mulched Farmland (PMF) can provide useful information for leveraging ...

OBJECTIVE Pectoral muscle flaps (PMF) are effective in terminating protracted sternal wound infections (SWI) but long-term outcome remains uncertain. Therefore, the aim of this study was to evaluate long-term outcome in patients treated with PMF. DESIGN Thirty-four of 263 patients revised because of deep SWI from 1991--2005 were treated with PMF. Of the 21 patients alive, 11 had left-sided, t...

Myeloproliferative neoplasms (MPNs) are a heterogeneous group of diseases including polycythemia vera (PV), essential thrombocythemia (ET), and primary(idiopathic) myelofibrosis (PMF). In this systematic review, we provide a comprehensive report on the incidence and prevalence of MPNs across the globe. Electronic databases (PubMed, EMBASE, MEDLINE, and Web of Science) were searched from their i...

PURPOSE The influence of JAK2 V617F mutation on blast transformation (BT) and overall survival (OS) in primary myelofibrosis (PMF) is controversial. In a large cohort of patients we applied competing risks analysis for studying the influence of JAK2V617F mutation on BT in PMF. PATIENTS AND METHODS In 462 PMF-fibrotic type patients (bone marrow [BM] fibrosis grade >0) we computed the incidence...

We show that the nitrate storing vacuole of the sulfide-oxidizing bacterium Candidatus Allobeggiatoa halophila has an electron transport chain (ETC), which generates a proton motive force (PMF) used for cellular energy conservation. Immunostaining by antibodies showed that cytochrome c oxidase, an ETC protein and a vacuolar ATPase are present in the vacuolar membrane and cytochrome c in the vac...
