occupational asthma is defined as “a disease of variable airflow limitations and/or airway hyper-responsiveness due to causes and conditions attributable to a particular occupational environment and not stimuli that are being encountered outside the workplace.” an analysis of general population-based studies published up to 2007 showed that 17.6% of all adultonset asthma is due to workplace exp...

OBJECTIVE To compare risk factors for severe disease as measured by admission to hospital and intensive care unit (ICU) and other clinical outcomes in children with pandemic H1N1 (pH1N1) versus those with seasonal influenza. DESIGN Retrospective analysis of children admitted to hospital with pH1N1 versus seasonal influenza A. SETTING Canadian tertiary referral children's hospital. PARTICI...

BACKGROUND Asthma is a condition, often chronic, characterized by respiratory symptoms, variable airflow limitation and/or airway hyper-reactivity with symptoms causally related to family history, environmental influences, exposure to viruses and allergens as examples. The high economic burden associated with asthma is associated primarily with health care costs, missed work or school days. Thi...

The present study aimed to investigate the clinicopathological features of cases of classic Kaposi's sarcoma (CKS) in Xinjiang Uygur Autonomous Region, China, and analyze its etiology and treatment. A total of 114 patients, who were clinicopathologically diagnosed with CKS at the First Affiliated Hospital of Xinjiang Medical University (Urumqi, China) between 1980 and 2015 were retrospectively ...

The role of consciousness in learning has been debated for nearly 50 years. Recent studies suggest that conscious awareness is needed to bridge the gap when learning about two events that are separated in time, as is true for trace fear conditioning. This has been repeatedly shown and seems to apply to other forms of classical conditioning as well. In contrast to these findings, we show that in...

We present a very general form of electronic friction as present when a molecule with multiple orbitals hybridizes with a metal electrode. To develop this picture of friction, we embed the quantum-classical Liouville equation (QCLE) within a classical master equation (CME). Thus, this article extends our previous work analyzing the case of one electronic level, as we may now treat the case of m...

In this paper, we present a method for estimating the local keys of an audio signal. We propose to address the problem of local key finding by investigating the possible combination and extension of different previous proposed global key estimation approaches. The specificity of our approach is that we introduce key dependency on the harmonic and the metric structures. In this work, we focus on...

— The axiomatic definition of mass in classical mechanics, outlined by Mach in the second half of 19th century and improved by several authors, is simplified and extended to the theory of special relativity. According to the extended definition presented here, the mass of a relativistic particle is independent of its velocity and coincides with the rest mass, i.e., with the mass defined in clas...

background: increased serum high sensitive c-reactive protein (hs-crp) in asthma and its association with disease severity has been investigated in many studies. this study aimed to determine serum hs-crp status in asthma versus healthy controls and to examine its ability in predicting asthma control. methods: serum crp was measured by elisa method using a high sensitive crp kit. severity of as...

Background: Asthma is a highly prevalent chronic respiratory disease in children. Moreover, the underlying causes of asthma exacerbation are important because they are effective in controlling and preventing asthma. The aim of this study was to evaluate the helicobacter pylori infection in controlled and uncontrolled asthmatic children compared to healthy children. Methods: This case- contro...
