Abstract (sommario):

Abstract Introduction Autologous epithelial cell spray, prepared with a commercial kit, is now widely used in American Burn Centers in extensive second and third degree burns where donor skin may be scarce. However, the cell viability and yield of the autologous skin suspension has not been assessed in a real-world setting and there is limited data on patient age and other demographics that may influence the number of viable cells in the suspension. The purpose of this IRB approved study was to evaluate the cell viability of an autologous skin cell suspension in a variety of age groups and Fit

Abstract (sommario):

The effects of iron content, fiber length, and stability of carbon nanotube (CNT) suspension on cells were examined. Five kinds of single-wall carbon nanotube (SWCNT) suspensions were prepared: with catalytic iron, without iron, long SWCNTs (stable), short SWCNTs (stable), and short SWCNT (unstable). These suspensions were applied to A549, THP-1, and mouse peritoneal macrophage cells. After a 24-h exposure, the mitochondrial activity, cell membrane damage, intracellular oxidative stress, and expression of cytokine genes were determined. Among these properties of SWCNTs, stability of CNT suspen

Abstract (sommario):

To produce calli for the establishment of a cell suspension, leaf, stem, and petiole explants of Lycopersicon chilense Dun., grown in vitro and in the soil, were cultured on media containing 15 different combinations of benzylaminopurine, kinetin, and indole acetic acid. Among the three types of tissues, leaf explants showed the best response. Cell suspension cultures of L. chilense were established from leaf callus derived from soil grown plants using Murashige and Skoog's medium supplemented with casein hydrolysate (250 mg/L), coconut water (5%), and 2,4-dichlorophenoxyacetic acid (2 mg/L).

An efficient method for the regeneration of shoots directly from cell suspensions of three commercial cultivars of lettuce (Lactuca sativa L. cv.

The effects of callus quality, light intensity, carbohydrate type and concentration, auxins, and cytokinins on cell growth and differentiation in the suspension culture were examined. Among these factors, callus quality and carbohydrates were the most critical. The optimal medium for regeneration of shoo

Secondly, 2400 groups of normal, cancerous and mixed cell models with different concentrations are generated by numerical simulation and their bioimpedance spectroscopy data

Abstract (sommario):

Histological analysis of Ruta graveolens L. roots and in vitro grown cell suspensions revealed idioblasts with vacuoles containing clusters of droplets thought to be the storage compartment of acridone alkaloids. These idioblasts contained numerous vacuoles of varying sizes rather than the large, single, central vacuole characteristic of most adjacent parenchyma cells. The structure of idioblasts in roots and suspension cultures was identical. Treatment of suspension cultures with fungal elicitors known to increase alkaloid accumulation greatly did not affect the structure of idioblasts.

Initiation of callus and induction of embryogenesis were achieved from both wiregrass and creeping bluestem.

The presence of 2,4-D was found to be essential for the induction and early development of embryoids, possibly up to the globular stage. In the case of bluestem, initiation of embryogenic callus required the presence of a low concentration of BA; using only 2,4-D resulted in more non-embryogenic callus. More globular embryos were formed wh

Deposition experiments in a Hull cell showed that high conductivity suspensions yield uniform deposits while low conductivity suspensions result in non-uniform deposits. This difference in deposition behavior is related to the resistance increase of the deposit during EPD. Impedance measurements during EPD showed that the ratio of the deposit resistance to the suspension resistance increases much more for high than for the low conductivity suspensions. They also showed that the total resistance of the EPD cell dropped almost to the suspension resistance after the electric field was turned off.

The aim of our research was to describe the structure and growth potential of a cell suspension of the tree fern Cyathea smithii. Experiments were performed on an established cell suspension with ½ MS medium supplemented with 9.05 µM 2,4-D + 0.88 µM BAP. In the experiments, attention was paid to the microscopic description of cell suspension, evaluation of cell growth dependent on the initial mass of cells and organic carbon source in the medium, the length of the passage, the content of one selected flavonoid in the post-culture medium, nuclear DNA content, ethylene production, and the antimi

Abstract (sommario):

A cell wall elicitor preparation from the needle pathogen Dothistroma pini was used to induce defence responses in Pinus radiata cell suspension cultures. Addition of elicitor to cell suspensions induced a rapid, transient burst in the accumulation of H2O2, with maximal response between 20 and 40 min post-elicitation. The protein kinase inhibitors staurosporine and K252a inhibited H2O2 accumulation showing that protein phosphorylation is required in the signal transduction pathway leading to the oxidative burst. Over a more extended time period elicitation of suspension cells lead to the activ

Abstract (sommario):

The influence of growth phase on the resistance of Staphylococcus aureus to the surface-active agents benzalkonium chloride and dodecylbenzyl sulfonic acid and the oxidizing agents sodium hypochlorite and hydrogen peroxide was studied. The resistances of cells in different growth phases were compared to those of solid medium cells grown according to the European phase 1 suspension test. Using cells from different growth phases (±3 × 107 CFU ml−1), we found that decline-phase cells were the most resistant cells. However, the decline-phase cell suspension contained more than 90% dead cells. A 10

The objective of this study was to establish cell suspension culture and plant regeneration via somatic embryogenesis of a Brazilian plantain, cultivar Terra Maranhão, AAB. Immature male flowers were used as explant source for generating highly embryogenic cultures 45 days after inoculation, which were used for establishment of cell suspension culture and multiplication of secondary somatic embryos. Five semisolid culture media were tested for differentiation, maturation, somatic embryos germination and for plant regeneration. An average of 558 plants per one milliliter of 5% SCV (settled cell

Phytocompounds enable plants to play a remarkable role as traditional remedies for human ailments. Due to their extremely low side effects, the ancient herbal medicinal systems are more beneficial than the modern medical systems. Gnidia glauca (Fresen.)

To determine whether secondary metabolite production could be enhanced, Hypericum cell suspensions were exposed to mycelia extract from the fungus Aspergillus flavus. Elicited Hypericum cell suspension cultures displayed reduced growth and viability and a modification of secondary metabolites production. Anthocyanins were only stimulated in fungal-elicited cell suspensions. Secondary metabolite pr

The nature of blood as a suspension of red blood cells makes computational haemodynamics a demanding task. Our coarse-grained blood model, which builds on a lattice Boltzmann method for soft particle suspensions, enables the study of the collective behaviour of the order of 10 6 cells in suspension. After demonstrating the viscosity measurement in Kolmogorov flow, we focus on the statistical analysis of the cell orientation and rotation in Couette flow. We quantify the average inclination with respect to the flow and the nematic order as a function of shear rate and haematocrit. We further rec

Rapid and high frequency somatic embryo regeneration from protoplasts isolated from 10 embryogenic cell lines of white spruce (Picea glauca) is reported. Embryogenic callus was initiated from immature zygotic embryos as source material for protoplast isolation. Individual cell lines exhibited different capabilities for sustained growth. Protoplast plating efficiencies depended on the concentrations of macroelements included in the medium. Using a medium with reduced salts, individual protoplasts developed directly into embryos with no disorganized growth period. Protoplasts from newly establis

Historically, the term "suspension effect" evolved during attempts to determine electrochemically the thermodynamically defined activity of H+ (aq) in suspensions. The experimental SE arises also in determining other pIon values, analogous to pH values.The SE relates to the observation

By varying the distance between the electrodes it is possible to separate the double layer and the suspension impedance from the measured data. Electrical ‘lumped’ models have been developed fro
