Abstract: We have developed and tested several highly diluted tinctures and here we describe the biological activity of M1, M2, and M8 both in vitro in immune cells from mice and human, and in vivo in mice. Cytotoxicity, cytokines released and NF-κB activation were determined after in vitro treatment. Cell viability, oxidative response, lipid peroxidation, bone marrow and lymph node cells immunophenotyping were accessed after mice in vivo treatment.None of the highly diluted tinctures tested were cytotoxic to macrophages or K562. Lipopolysaccharide (LPS)-stimulated macrophages treated with all highly diluted tinctures decreased tumour necrosis factor alpha (TNF-α) release and M1, and M8 decreased IFN-γ production. M1 has decreased NF-κB activity on TNF-α stimulated reporter cell line. In vivo treatment lead to a decrease in reactive oxygen species (ROS), nitric oxide (NO) production was increased by M1, and M8, and lipid peroxidation was induced by M1, and M2. All compounds enhanced the innate immunity, but M1 also augmented acquired immunity and M2 diminished B lymphocytes, responsible to acquired immunity.Based on the results presented here, these highly diluted tinctures were shown to modulate immune responses. Even though further investigation is needed there is an indication that these highly diluted tinctures could be used as therapeutic interventions in disorders where the immune system is compromised.Highly diluted substances and tinctures are usually intended to enhance the immune system resulting in reduced frequency of various diseases. The immune system is a complex network that integrates lymphoid organs, cells, humoral factors, and cytokines. The essential function of the immune system is host defense, but when it does not work properly the disease emerges. For instance, underactivity may result in severe infections and tumors of immunodeficiency, overactivity in allergic and autoimmune disease [1].

Abstract: the present work describes a low-cost electrochemical "wall-jet" detector for flow analysis. the electrolytic solution enters into the cell through a tube of stainless steel (200 to 300 μm i.d), reaching to the center of the working electrode perpendicularly and then being mixed to the remaining solution in the cell, which flows under atmospheric pressure into a waste reservoir. the proposed electrochemical detector can be used with any type of working electrode, from commercial to home-made, such as glassy carbon and metallic electrodes (modified or unmodified), which enlarge the applications of the electrochemical detector.

Abstract: it was evaluated the annual evolution of global, direct and diffuse components of incident solar radiation on tilted surfaces to 12.85, 22.85 and 32.85o, facing north, in botucatu, state of s?o paulo, brazil. the radiometric fractions were obtained for each component of the radiation in the aforementioned surfaces, through the ratio with the global and top of the atmosphere radiations. seasonality was evaluated based on monthly averages of daily values. the measures occurred between 04/1998 and 07/2001 at 22.85o; 08/2001 and 02/2003 at 12.85o; and from 03/2003 to 12/2007 at 32.85o, with concomitant measures in the horizontal surface (reference). the levels of global and direct radiation on tilted surfaces were lower in summer and higher in the equinoxes when compared with the horizontal. the diffuse radiation on tilted surfaces was lower in most months, with losses of up to 65%. a trend of increasing differences occurred between horizontal and tilted surfaces with the increase of the angle in all the components and fractions of incident radiation. the annual evolution of rainfall and cloud cover ratio directly affected the atmospheric transmissivity of direct and diffuse components in the region.

Abstract: the hydrological behavior of watersheds derives mainly from climate variability and land use. the 'ribeir?o jo?o leite' watershed is the main sourse of water supply in goiania city, and recently intense modifications were observed in the land use and availability of water. in this context, this work proposes to classify the land use between 1979 and 2005 and establish the association of the runoff with the land use and climate variability. for this, landsat images from the years 1979, 1989, 1997 and 2005 were used as well as flow and rainfall data provided by the agência nacional de água (ana). the land use was marked by 17.8% of deforestation, expansion of the urbanization and agriculture corresponded to 6.6 and 15.2%, respectively, and by significant areas of pasture. a trend of reduction in flow was observed that could be explained, in part, by a reduction in the rainfall regime. however, due to the significant increase of water withdrawal and the lack of historical records, there was difficulty in qualitative association between the runoff and the land use in spite of generating linear regression models with coefficients of determination (r2) above 0.75.
