Objective(s): One of the main constraints of collagen hydrogel scaffolds for using in tissue engineering is mechanical weakness. Plastic compression (PC) is a physical method to overcome the mechanical limitation of collagen hydrogel. Materials and Methods: In this study, the effects of pH on mechanical and biological properties of PC hydrogels were investigated. Collagen hydrogels were fabrica...
conclusions over-expression of the synthetic cpc/β protein in the bacterial system (escherichia coli bl-21) showed that e. coli can be used as a basis for further research to produce this desired protein in large quantities. results the sds-page analysis and dot blotting confirmed the production of recombinant c-pc/β in the bacterial expression system. over-expression of cpcb gene was optimized...
background : this research provides an insight into exposure information and particle size distributions of bisphenol a (bpa), a common environmental hormone, at polycarbonate (pc) molding plants in southern taiwan. methods : the inhalable dust sampler as iom and the micro-orifice uniform deposition impactor (moudi) were used for samples collection to evaluate the level and particle size distri...
Material movement is a significant and costly aspect of gold or general mining projects. This involves the utilization expensive heavy equipment, necessitating careful management to ensure optimal efficiency. Therefore, this study aimed analyze productivity excavators PC-300 PC-400 as well compare theoretical calculation results with actual conditions. The basis was formed by real field data, c...
Differential effect of surfactant and its saturated phosphatidylcholines on human blood macrophages.
Blood monocyte-derived macrophages invading the alveolus encounter pulmonary surfactant, a phospholipoprotein complex that changes composition during lung development. We tested the hypothesis that characteristic phosphatidylcholine (PC) components differentially influence macrophage phenotype and function, as determined by phagocytosis of green fluorescent protein-labeled Escherichia coli and ...
BACKGROUND Palliative care (PC) is a critical component of comprehensive cancer care. Previous studies on PC access have mostly examined the timing of PC referral. The proportion of patients who actually receive PC is unclear. We determined the proportion of cancer patients who received PC at our comprehensive cancer center and the predictors of PC referral. METHODS We reviewed the charts of ...
Predictor-corrector (PC) methods for the numerical solution of stiff ODEs can be extended to include the second derivative of the solution. In this paper, we consider second derivative PC methods with the three-step second derivative Adams-Bashforth as predictor and two-step second derivative Adams-Moulton as corrector which both methods have order six. Implementation of the proposed PC method ...
