During drying the variation in loss of weight and tomato temperature was continuously measured, and tomato samples were taken to make a visual evaluation of color and to determine the lycopene, ascorbic acid and 5-hydroxymethyl-2-furfural (HMF) contents. Color, ascorbic acid and HMF contents indicated severe oxidative heat damage during drying. Conversely, lycopene had a high stability during drying. The lycopene content decreased to a maximum of 10% after drying at 110 C and did not change during drying at 80 C. #

As a general trend, up until now, most studies on the biosorption of heavy metal ions by miscellaneous biosorbent types have been directed toward the uptake of single metal in preference to multicomponent systems. In particular, Langmuir and Freundlich models are the most common isotherms for correlating biosorption experimental data though other isotherms, which were initially established for gas phase applications, can also be extended onto biosorption system. In kinetic modeling, the pseudo-first and -second order equations are considered as the most celebrated models.

Fundamental research could make important contributions to our understanding of the mechanisms of action of homeopathic treatments. Plant-based bioassays are suitable for basic research -lacking the placebo effect and ensuring large data samples for structured statistical analyses. Objective: The aim of this study was to reproduce a previous experiment on the effects of arsenic trioxide (As2O3) high dilutions on wheat seedling growth in order to verify whether the same significant results could be obtained working in a different place and with a different experimental team. A further goal was to investigate high dilution effects on variability. Material and Methods: A structured experiment was performed blind over 9 weeks, using wheat seeds previously stressed with a sublethal dose of As2O3. The seeds were then treated with either potentized As2O3 (5x, 15x, 25x, 35x, 45x), potentized water (equivalent potencies) or diluted As2O3 (10 -5 , 10 -15 , 10 -25 , 10 -35 , 10 -45 ). The working variable was the stem length, measured after 4, 5, 6 and 7 days. Results: Some potencies (As2O3 45x and H2O 45x) induced a relevant increase in seedling growth and/or a variability decrease. Diluted As2O3 did not induce any significant results. Conclusions: Confirmation of a significant stimulating effect on seedling growth and a significant decrease of variability was obtained with ultra-high dilutions at the 45x potency. The model of wheat germination and growth has been confirmed to be a good tool for basic research in homeopathy.

Some potencies, such as As 2 O 3 40x, 42x and 45x, have repeatedly shown a signi®cant stimulating effect on germination compared to controls, whereas As 2 O 3 35x has a signi®cant inhibiting effect.
