In this paper, we explore a nonlinear mathematical model to study the spread of asthma due to inhaled pollutants from industry as well as tobacco smoke from smokers in a variable size population. The model is analyzed using stability theory of differential equations and computer simulation. It is shown that with an increase in the level of air pollutants concentration, the asthmatic (diseased) ...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
THE STUDY WAS THE FIRST TIME TO ESTABLISH AND COMPARE TWO RAT MODELS OF TWO COMMON SYNDROMES: Kidney Yang Deficiency syndrome (KYDS) in traditional Chinese medicine (TCM) and abnormal savda syndrome (ASS) in traditional Uighur medicine (TUM). Then, we also established and evaluated rat models of combining disease and syndrome models of asthma with KYDS or ASS. Results showed that usage of the h...
asthma is a chronic inflammatory disease of the airway with extensive airway remodeling. the ethical issues associated with the studies in asthmatic patients, required development of animal model of asthma. animal models of asthma can provide valuable information on several features of asthma pathogenesis and treatment. although these models cannot carry out all clinical features, they are valu...
Abstract Background and purpose: Asthma is one of the most common chronic diseases worldwide and its prevalence has increased over the past decades in industrialized and developing countries. Cox proportional hazards model is one of the main models used in the analysis of survival data. This study was performed to evaluate the Stratified cox model in identifying the factors influencing readm...
Background & Aims: Asthma is the most important chronic disease in school-age children. The effects are significant in terms of increased economic costs, decreased quality of life, hospitalization, absenteeism, and death. The purpose of this study was to investigate the effect of family-centered education based on the Health Belief Model on absenteeism and hospitalization of 6 to 12-year-old ch...
Animal models of asthma have been used for over 100 years. The accuracy of extrapolations from animal models to human asthmatics is highly dependent on the species of animal selected. The rat, in comparison with other animals, demonstrates many features of airway allergy and allergic asthma that are similar to the human conditions. The following features of human asthma can be effectively inves...
background: black seed (bs) is used in traditional medicine as a therapy for a variety of diseases including allergic asthma. materials and methods: in the present study, anti-inflammatory and immunomodulatory effects of bs on cytokine gene expression, lung airway eosinophilia and goblet cell hyperplasia were examined in a mouse mice model of allergic asthma. groups of 6-week-old female balb/c ...
The ovalbumin (OVA)-induced airway inflammation in rats is a commonly used model to explore the pathobiology of asthma. However, its susceptibility varies greatly between rat strains, and presently Brown Norway (BN) rats are preferentially used. Since recruitment of T cells to the lungs depends on the CD26 (dipeptidyl peptidase IV, DPPIV) expression, Fischer 344 strain (F344) rats are a highly ...
