The influence of two carbon sources, sorbitol and sucrose on In vitro shoot proliferation and rooting of peach rootstock GF 677 was compared at 15, 30, 45 and 60 g l concentrations. The highest number of shoots per proliferated explant, usable shoots and shoots having maximum fresh weight were obtained on sorbitol at 30 g l. GF 677 does not seem to be an efficient utilizer of sucrose for In vit...

The nature and behavior of the microbial population developed on a synthetic waste containing salts and sorbitol are compared to that of a treatment-plant activated sludge. The population of the adapted sludge developed on the synthetic waste consisted approximately of only six kinds of bacteria. Experiments with radioactive sorbitol indicate that the microbial population developed on the synth...

Abstract Changing relative humidity levels challenge the manufacturing of chewable xylitol-sorbitol based tablets. The aim study is to investigate how formulation tablets affects properties powder blends and in an environment different levels. In all, 30 batches containing ratios sorbitol, xylitol magnesium stearate were prepared at three Powder made into using instrumented eccentric tableting ...

The aim of this study was to examine the effect of D-sorbitol on the gelation characteristics of methylcellulose in aqueous solution. The addition of D-sorbitol at concentrations of between 25 and 30% (w/v) to 1.0-2.0% (w/v) methylcellulose solutions reduced the gelation temperature from approximately 53 degrees Celsius to values between ambient and 37 degrees Celsius and increased the strength...

Insulin-depleted, normal rabbit corneal epithelium was incubated in vitro in tissue culture medium containing high concentrations of glucose (35 mM). These short-term incubations showed that the epithelium took up glucose equally whether or not insulin had been added to the medium, indicating that corneal epithelium is an insulin-insensitive tissue. Sorbitol accumulation showed that the normal ...

Polyols are enzymatically-produced plant compounds which can act as compatible solutes during periods of abiotic stress. Nicotinamide adenine dinucleotide(+)-dependent SORBITOL DEHYDROGENASE (SDH, E. C. 1.1.1.14) from Arabidopsis thaliana L. sorbitol dehydrogenase (AtSDH) is capable of oxidizing several polyols including sorbitol, ribitol, and xylitol. In the present study, enzymatic assays usi...

The induction of cell death in human erythroleukemic cells (K562) by sorbitol shows the typical apoptotic changes in ultrastructural morphology, including blebbing, chromatin condensation and nuclear membrane breakdown. Using a cytofluorimetric approach, we found that sorbitol induced production of reactive oxygen species (ROS) followed by DNA fragmentation in leukemic cells. In this study, we ...

Neurodegeneration is an important component of diabetic retinopathy as demonstrated by increased neural apoptosis in the retina during experimental and human diabetes. Accumulation of sorbitol and fructose and the generation or enhancement of oxidative stress has been reported in the whole retina of diabetic animals. Aldose reductase (AR), the first and the rate limiting enzyme in the pathway r...
