Two groups of antibodies against mouse resident alveolar and peritoneal macrophages have been raised individually in rabbits by immunization with whole cell suspensions of lavaged alveolar and peritoneal macrophages. The whole antisera reacted positively with neutrophils and lymphocytes. However, upon extensive absorptions with these cells the activity became restricted to macrophages. The...
aspergillus species (a flavus and a niger) are important sources of inhalant allergens. current diagnostic modalities employ crude aspergillus extracts which only indicate the source to which the patient has been sensitized, without identifying the number and type of allergens in crude extracts. we report a study on the identification of major and minor allergens of the two common air...
abstract autoimmune pancreatitis (aip) is a rare disorder that may be present as common bile duct stricture. the patient was a seventy-year-old man with presentations as recurrent abdominal pain and jaundice, elevated billirobin (bil) and elevated alkaline phosphatase (alkp) in association with the presence of hetrogenesity of the pancreatic head and dilated intra and extra hepatic bile ducts i...
background & aim: a meta-analysis refers to the statistical synthesis of results from a series of studies and has been used to estimate pooled prevalence of human diseases. in this study, we review some statistical issues regarding the meta-analysis of the prevalence of human diseases such as statistical software and programs, transformations of prevalence rate, assessment of heterogeneity, and...
one of the leading causes of death in the world are cardiovascular diseases, among which coronary artery disease (cad) is the most common one. it occurs as a result of narrowing of the arteries which supply blood to the heart due to a theroma plaque formation. this kind of heart disease can be considered as a multifactorial one as genetic and environmental factors are involved in its incidence....

reservoir models with many grid blocks suffer from long run time; it is hence important to deliberatea method to remedy this drawback. usual upscaling methods are proved to fail to reproduce fine gridmodel behaviors in coarse grid models in well proximity. this is attributed to rapid pressure changesin the near-well region. standard permeability upscaling methods are limited to systems with lin...
The process to provide integrated access to several, independent information sources is not easy, due to semantic heterogeneities which lead to semantic connicts or contradictions. In this paper we present a discussion about the existence of contradictions, their importance and how they can be handled when the need of cooperation arises.
Approaches such as DeFries-Fulker extremes regression (LaBuda et al., 1986) are commonly used in genetically informative studies to assess whether familial resemblance varies as a function of the scores of pairs of twins. While useful for detecting such effects, formal modeling of differences in variance components as a function of pairs' trait scores is rarely attempted. We therefore present a...
