background one of the major clinical problems regarding pseudomonas aeruginosa is attributed to metallo-beta-lactamases (mbl). this group of enzymes is a subset of beta lactamases which belong to group b of ambler classification and cause hydrolysis of carbapenems. based on epidemiological studies conducted worldwide, it is proved that prevalence of genes coding mbls in p. aeruginosa species ar...
cytokines play a part in pathogenesis of periodontitis via inflammation phenomenon. aggressive periodontitis (agp) is a multifactorial disease resulting in rapid tooth loss due to severe destruction of tooth supporting apparatus. recently, researchers have focused on genetic susceptibility of periodontitis through investigating the gene variations of cytokines and other components of immune res...

Background and Aims: Chondrocytes and their differentiation play a central role in joint diseases. Effect of the transforming growth factor (TGF)-β1 on chondrocyte characteristics and differentiation is not clearly understood. This study was undertaken to investigate the effects of TGF-β1 on tissue characteristics and morphology of chondrocytes against degradation induced by interleuk...
Let $(X, \tau)$ and $(Y, \sigma)$ be topological spaces in which no separation axioms are assumed, unless explicitly stated if $\mathcal{I}$ is an ideal on $X$.Given a multifunction $F\colon (X, \tau)\rightarrow (Y, \sigma)$, $\alpha,\beta$ operators \tau)$, $\theta,\delta$ proper $X$. We introduce study upper lower $(\alpha, \beta,\theta,\delta,\mathcal{I})$-continuous multifunctions.A said to...
