This study proposes a control strategy for the efficient semi active suspension systems utilizing a novel hybrid PIDfuzzy logic control scheme .In the control architecture, we employ the Chaotic Fruit Fly Algorithm for PID tuning since it can avoid local minima by chaotic search. A novel linguistic rule based fuzzy logic controller is developed to aid the PID.A quarter car model with a non-line...
We measured the luminol- and lucigenin-enhanced chemiluminescent response of human polymorphonuclear leukocytes (PMN) stimulated by various strains of Streptococcus pneumoniae and Haemophilus influenzae. In the absence of opsonin, phagocytosis of either bacterial species elicited good PMN response when the bacteria were adhered to a surface but minimal PMN response when they were in suspension....
Although the combination of toluidine blue O (TBO) dye and laser light at a wavelength of 633 nm has a bactericidal effect, light from laboratory lasers can only be directed externally at a bacterial colony or suspension. In this study a novel delivery system guided the laser light to an 800-micrometer diameter spherical tip (an isotropic tip) from which light radiated producing a uniform spher...
Biofilm formation in microfluidic channels is difficult to detect because sampling volumes are too small for conventional turbidity measurements. To detect biofilm formation, we used an ion-sensitive field-effect transistor (ISFET) measurement system to measure pH changes in small volumes of bacterial suspension. Cells of Micrococcus luteus (M. luteus) were cultured in polystyrene (PS) microtub...
Background and Objectives: Increased bacterial (streptococcal) biofilm aggregation on the surface of resin composite restorations in comparison with amalgam and glass ionomer restorations makes the composite restorations susceptible to secondary caries next to the restorations. In this study, the anti-Streptococcus mutans properties of resin composites containing silver nanoparticles were inve...
background and objectives: bacteria need iron for growth and most of them can actively acquire fe ions using especial iron-chelating proteins which named siderophores. we aimed to determine the frequencies of iuca, iron and irp2 genes in the uropathogenic escherichia coli (upec) isolates. we also analyzed the effects of siderophore genes beside iron supplements on growth rate of the isolates. m...
The posaconazole tablet formulation was developed to have improved bioavailability compared to the oral suspension. Here, we compared posaconazole plasma concentration (PPC) with the posaconazole oral suspension versus the tablet in Korean patients undergoing remission induction chemotherapy for hematologic malignancies. PPC was measured at 3, 8, and 15 days of treatment with the oral suspensio...
abstract the mutagenic and immunosuppressory effects of cyclophosphamide (cyp) are still the primary limitation to wider application for treating a variety of human malignancies. on the one hand, cyp treatment predisposes transplant recipients and cancer patients to risk of bacterial, fungal, and viral infections, in the other word the, lipopolysaccharide (lps), an endotoxin found in cell wal...
Cefixime is a broad-spectrum oral antibiotic used for treating wide variety of bacterial infections. This investigation was aimed to study the pharmacokinetics and bioequivalence new generic suspension containing 100 mg cefixime trihydrate per 5 ml as test product against reference formulation Suprax® after administration 28 Arabic healthy male adult subjects under fasting condition. Ten millil...
Background: Magnetic separation using magnetic nanoparticles can be used as a simple method to isolate desulfurizing bacteria from a biphasic oil/water system. Objectives: Magnetite nanoparticles were applied to coat the surface of Rhodococcus erythropolis IGTS8 and Rhodococcus erythropolis FMF desulfurizing bacterial cells, and the viability and...
