The sterols and sterolins in rice bran are potent immunomodulators. The best response was obtained with a 100 1 sterol/sterolin mixture that demonstrated T-cell proliferation from 20% to 920% and active cell antigens after four weeks in human subjects (Bouic et al, 1996). Another in vitro experimental study with sterol/sterolins, demonstrated a significant increase in cytokinines, interleukin-2 and y-interferon between 17% and 41 % in addition to an increase in natural killer cell activity. These experiments (Bouic et al, 1996) prove that sterol/sterolins are potent immunomodulators with important implications for the treatment of immune dysfunction. Rice bran products are excellent dietary supplements for the improvement of immune function. It is probable that the effects of rice bran on diabetes, CVD and cancer all result from improved immune function. 

The barrier properties of human skin have long been an area of multidisciplinary research. Skin is one of the most difficult biological barriers to penetrate and traverse, primarily due to the presence of the stratum corneum. The stratum cor-neum is composed of comeocytes laid in a brick-and-mortar arrangement with layers of lipid. The corneocytes are partially dehydrated, anuclear, metabolically active cells completely filled with bundles of keratin with a thick and insoluble envelope replacing the cell membrane [29]. The primary lipids in the stratum corneum are ceramides, free sterols, free fatty acids and triglycerides [30], which form lamellar lipid sheets between the corneocytes. These unique structural features of the stratum comeum provide an excellent barrier to the penetration of most molecules, particularly large, hydrophilic molecules such as ASOs.

The dashed box shown above now surrounds the column of data in cells D2-D10, which appear as arguments of the SUM function in cell D11 and in the formula bar. Note that Excel assumes that you want to add all of the numerical data above the active cell and automatically completes the formula. When you type [ J], the sum of the squares of the deviations appears in cell Dll. Since cells D8-D10 are blank, they contribute zero to the sum, and so there is no harm in leaving the references to D8-DI0 in the formula. Be aware, however, that references to blank cells could pose difficulty under certain circumstances. You can always resize the box to include only the data of interest. 

In column B we will now calculate a sine wave. Activate cell B1 and deposit the heading sine . Move to cell B3 and deposit the formula = sin(a3 pi()/4). The equal sign identifies this as a formula rather than as text the asterisk indicates a multiplication. The spreadsheet uses the notation pi() to denote the value of tt the brackets alert the computer that this is a function. Excel instructions do not distinguish between lower case and capitals, but the formula bar always displays them as capitals, which are more clearly legible. By now your spreadsheet should look like that depicted in Fig.1.3-1. 

As a first important result, these trials confirmed the excellent safety profile of completely synthetic peptides in general, and poly-L-arginine in particular. Furthermore, several important lessons regarding the activation of human T cells were learned in both studies, T cell responses were assessed using [ H]-thymidine prohf-eration and IFN-y ELIspot assays, and fluorescence-activated cell sorting (FACS). 

This exercise introduces two new features of the EXCEL software the matrix multiplication and transpose macros MMULT() and the TRANSPOSE(). These are best activated using the =/ icon on the TOOLBAR and the option to drag out the array data to be multiplied, visible in the function window. You select an equal area of blank cells on the spreadsheet and then activate the MMULT() or TRANSPOSEO macros. Note too that after selecting the particular area for each array, the sequence to enter these cell references requires CTL/SHIFT/ENTER. Otherwise, only one entry will appear in the top-left hand cell of the chosen active cells for the operation. 

This chapter begins by discussing the basic makeup of Microsoft Excel, a common spreadsheet. We will explain how a spreadsheet is divided into rows and columns, and how to input data or a jbrmula into an active cell. We will also explain the use of other tools such as Excel s mathematical, statistical, and bgcalfimctions. Pbtting the results of an engineering analysis ming Excel is also presented. 

It is generally accepted that the active cells in the adrenal cortex are those of the zona fasciculata, which secrete corticosteroids under the influence of ACTH. The secretion of the various corticosteroid hormones implies that a complex system of enzymes is involved which characterizes the biochemical differentiation of the cells of the zona fasciculata. The reader will find an excellent account of the biology of the adrenal cortex in the recent work of Chester Jones (1957). 

Field tests indicate that a properly designed unit with a suitahle chemical treatment program should have oil removal efficiency between 40% and 55% per active cell and an overall efficiency of about 90%. An excellently designed system might exhibit an efficiency as high as 95%, while a poorly designed, poorly operated unit, or difficult oil-water chemistry could easily degrade performance to as low as 80%. Equation (3.25) verifies the above efficiencies. For example, Equation (3.25) shows that a three-cell unit can be expected to have an overall efficiency of 87% while a four-cell unit can be expected to have an overall efficiency of 94%. The unit s actual efficiency will depend on many factors that cannot be controlled or predicted in laboratory or field tests.
