aspergillus spp. are ubiquitous saprophytic fungi that cause a variety of diseases, ranging from hypersensitivity reactions to flulike pneumonia and life-threatening invasive aspergillosis. as the lung is the primary site of initial infection with airborne conidia, we investigated the innate immune responses of bronchial epithelial cells against different forms of aspergillus spp.

abstract the effect of land use type on soil functioning within an ecosystem can be assessed and monitored using soil quality attributes. such studies, which are carried out to create a balance between the biological production and the maintenance and improvement of land resource quality, provide a framework for land degradation control and also for identification of sustainable management. in ...

the emph{harary index} $h(g)$ of a connected graph $g$ is defined as $h(g)=sum_{u,vin v(g)}frac{1}{d_g(u,v)}$ where $d_g(u,v)$ is the distance between vertices $u$ and $v$ of $g$. the steiner distance in a graph, introduced by chartrand et al. in 1989, is a natural generalization of the concept of classical graph distance. for a connected graph $g$ of order at least $2$ and $ssubseteq v(g)$, th...

background: recent researches have known long term infections such as periodontal disease to be related with the process of atherosclerosis. periodontitis causes peripheral inflammation and immune cell stimulation which leads to an increase in c - reactive protein (crp) and iga ab and there is a definite relation between cardiovascular disease, crp increase and periodontitis. the aim of this st...
