the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
purpose: to describe a novel surgical technique for in vivo limbal stem cell cultivation for reconstruction of corneal epithelium in total limbal stem cell deficiency (lscd). methods: patients suffering from chronic total unilateral lscd due to a chemical injury were sequentially included. one small limbal block (2x1 mm) harvested from contralateral healthy eye sutured over the amniotic membran...
this paper reviews recent strategies used for increasing specific yield and productivity in high cell density cultures. high cell density cultures offer an efficient means for the economical production of recombinant proteins. however, there are still some challenges associated with high cell density cultivation (hcdc) techniques. a variety of strategies in several aspects including host design...

Background and purpose: The 50 KDa protein (50 µg) in carboxylic domain of the neurotoxin heavy chain (BoNT/A-Hc) recognizes surface receptors on target neurons and this fragment contains the principle protective antigenic determinants. Recently, this fragment has been used as a recombinant vaccine candidate for botulism. The study aimed to compare the evaluation of BoNT/A-Hc production in fed-...
Cell-based therapies have generated great interest in the scientific and medical communities, and stem cells in particular are very appealing for regenerative medicine, drug screening and other biomedical applications. These unspecialized cells have unlimited self-renewal capacity and the remarkable ability to produce mature cells with specialized functions, such as blood cells, nerve cells or ...
Fixed-bed reactors have gained growing attention for the cultivation of mammalian cells. They allow for a low shear stress cultivation of adherent and non-adherent cells due to the immobilization of cells within macroporous carriers. Their potential has been demonstrated for many cell culture purposes. Some of the recent developments are presented in this review, including improved antibody pro...
BACKGROUND Cell and tissue homeostasis results from the dynamic balance of cell - cell and cell - extracellular component crosstalk that regulates proliferation, differentiation, and apoptosis of cells as well as secretion and activation of soluble factors and/or deposition of extracellular matrix (ECM) components. AIM The aim of the work was to study the crosstalk between tumor cells and str...
the objective of this research was to investigate the influence of the over-expression of recombinant interferon-g during high cell density cultivation on cellular characteristics of recombinant e. coli. batch and fed-batch culture techniques were employed to grow escherichia coli bl21 for production of human gamma-interferon in pet expression system. final cell densities in batch and fed-batch...
