The objective of this study was to investigate the growth rate of Chlorella vulgaris for CO2 biofixation and biomass production. Six mathematical growth models (Logistic, Gompertz, modified Gompertz, Baranyi, Morgan and Richards) were used to evaluate the biomass productivity in continuous processes and to predict the following parameters of cell growth: lag phase duration (λ), maximum specific...

Whole-cell pertussis vaccine (wP) has been imperative and highly effective in preventing childhood deaths due to pertussis. Pertussis toxin is one of the virulence factors of Bordetella pertussis in all available pertussis vaccines. wP production in Razi Vaccine and Serum Research Institute is according to bioreactor culture of B. pertussis strains in B2 medium. The aim ...

background: both azadirachtin and rotenone, two botanical pesticides have shown inhibit the growth of cultured insect cells. the inhibitory effect of rotenone on cell growth is through disruption of electron transport chain, but exact mechanism of effect of azadirachtin on growth of cell is unknown. this study was carried out to compare the effect of these phytochemical on oxygen consumption by...

conclusions dlec1 suppresses tumor cell growth the presence of ap-2α2 and stimulates cell proliferation in the down-regulation of ap-2α2 in dlec1 over-expression stable clones of htc116. results the dlec1 over-expression was found to reduce the number of colonies in colony formation and to induce g1 arrest in seven clones, and apoptosis in one clone in the cell cycle analysis. furthermore, rega...

Introduction: Introduction: Molecular components within the microenvironment act upon cell growth, survival/apoptosis, and proliferation. Immune system cells respond to molecules produced by the tumor and released in the surrounding microenvironment, such as cytokines, chemokines, and growth factors. This study aimed to identify the effects of tumor environment on monocyte-macrophage cell linea...

conclusions this study delineated the beneficial role of rsv for growth regulation of skin cancer cells and highlighted the involvement of rsv in the induction of apoptosis in a431 cells. these findings might conduct evidence into the oncolytic properties of rsv in the skin cancer. further studies are required to indicate intracellular targets for rsv-induced apoptosis in skin cancer cells. res...
