Matrix metalloproteinases (MMPs) are implicated in the pathogenesis of various inflammatory diseases of the central nervous system. Evidence is accumulating that gelatinase B (MMP-9) might be involved in the pathogenesis of meningitis, but the spectrum of different MMPs involved in the inflammatory reaction of this disease has not been determined. We investigated the temporal and spatial mRNA e...

The corpus luteum (CL) is a transient endocrine organ that secretes progesterone to support pregnancy. The CL is formed from an ovulated follicle in a process that involves extensive angiogenesis and tissue remodeling. If fertilization does not occur or implantation is unsuccessful, the CL will undergo regression, which involves extensive tissue degradation. Extracellular proteases, such as ser...

background: hypertension is one the most common causes of chronic kidney disease (ckd). one of the major concerns in hypertensive patients is early detection of renal disorders. in the past, serum creatinine (scr) concentration was used as a marker of kidney function, but it proffers a late reflection of reduced glomerular filtration rate. cystatin c and neutrophil gelatinase-associated lipocal...

objective(s) the aim of the present study was to compare the therapeutic indices of several agents used in treatment of inflammatory conditions which included: vitamin e, hydro-alcoholic extracts of glycyrrhiza glabra, matricaria aurea, dexamethasone, piroxicam and diclofenac using wehi-164 fibrosarcoma cells. materials and methods cytotoxicity evaluation was based on vital dye exclusion assay....

objective(s) lipocalin 2 (lcn2) is a 25-kda glycoprotein that has initially been extracted from neutrophil granules. expression of lcn2 is induced under various pathophysiological conditions. it is also known as an early marker of kidney and heart injury. high-level expression of recombinant lcn2 neutrophil gelatinase-associated(ngal) in insect cells was the aim of this study. materials and met...

w The human wrnea is a densely innervated struchxe. However, data on nerve fiber (NF) distribution in tbe human cornea are scarce possibly due to fast post mortem degeneration. Therefore, moat descriptions on comeal innervation are based on studies in rats and rabbits. Tbe present study is focussed on the ulaastruaure of NF’s in the central and peripheral human cornea. Methods: Tissue samples o...

objective(s):n-myc downstream regulated gene 2 (ndrg2) is a candidate gene for tumor suppression. the expression of ndrg2 is down-regulated in several tumors including lung cancer. the aim of this study was to explore the effect of ndrg2 overexpression on invasion, migration, and enzymatic activity of matrix metalloproteinase-2 (mmp-2) and -9 (mmp-9) in human lung adenocarcinoma a549 cells.  ma...
