Background: Implantation is characterized by the interaction of two immunologically and genetically distinct tissues. The embryo differs from the cells of the mother, and would be rejected as a parasite by the immune system of the mother if it didn’t secrete immunosuppressive agents. Thus, immunological rejection of the fetus due to recognition of paternal antigens by the maternal immune system...

multiple sclerosis (ms) is an inflammatory, multifocal, immune-mediated disease of the central nervous system that women are at a higher risk to acquire than men. myxovirus resistance protein a (mxa) is used as a predictive marker of bioactivity of interferon-beta (ifn-β) therapy in ms patients. this study was undertaken in west of iran to investigate gender differences in the expression level ...

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...

Existing conditional expression systems can be classified in two major categories that are based either on the induction or on the de-repression of transcription. The system described here combines both mechanisms, since a unique transcription factor can be shifted from a repression to a stimulation activity by simply changing its ligand. The resulting advantage of this system is the complete a...

Artificially regulating gene expression is an important step in developing new treatment for system-level disease such as cancer. In this paper, we propose a method to regulate gene expression based on sampled-data measurements of gene products concentrations. Inherent noisy behaviour of Gene regulatory networks are modeled with stochastic nonlinear differential equation. To synthesize feed...
