CAPTURE analysis program

The DNA in the sections is denatured by treatment with 70% formamide/2 x SCC for 5 min at 80°C. Ten microliters of the probe solution (hybridization buffer 7 pd, probe 1 pi, and distilled water 2 pi) is placed on the slide and coverslipped. The slide is placed in a microwave oven (2.45 GHz, 300 W) and heated for 3 sec at 2-sec intervals for a total of 15 min at 42°C. DAPI II (4,6-diamidine-2-phenylindol) (125 ng/ml) is used for nuclear staining. The sections are promptly observed under a fluorescent microscope equipped with epifluorescence filters and a photometric CCD camera. The captured images are digitized and stored in an image analysis program.

Methods have been described for determining chlorinated aliphatic hydrocarbons in soil and chemical waste disposal site samples. The latter method involves a simple hexane extraction and temperature programmed gas chromatographic analysis using electron capture detection and high resolution glass capillary columns. Combined gas chromatography-mass spectrometry was used to confirm the presence of the chlorocarbons in the samples [4],... 

Gas Chromatographic Analysis. We used temperature programmed glass capillary gas chromatography to separate PCB residues. Use of an electron capture detector required an efficaceous sample cleanup for isomer quantitation (27). These combined techniques offered enhanced separations and enabled us to identify and quantitate individual PCB constituents (jL> 27). Schwartz (27) separated more than 100 constituents from a 1 1 1 1 mixture of Aroclors 1242, 1248, 1254, and 1260. 

Analysis of extracts was performed on a gas chromatograph (GC) (5880A, Hewlett-Packard) equipped with an electron-capture detector (ECD) and a 30-m fused silica capillary column with an outer diameter of 0.25 mm and a film thickness of 0.25 xm (Durabond DB-5, J W Scientific). The internal standard method developed by Dunnivant and Elzerman (15) was used, except that that only one internal standard was used (Aldrin) to minimize run time on the gas chromatograph. Daily working standards were composed of 80% Aroclor 1016 and 20% Aroclor 1254. This ratio was chosen because it matches the Aroclor distribution found in the sediments by Polansky (13). Quantification and collation of data were done on microcomputers with a spreadsheet program (SuperCalc 4, Computer Associates International). 

When determining which method of economic analysis she should use, she eliminated cost-minimization analysis because the treatment alternatives (service versus no service) will not result in equivalent outcomes. A cost-effectiveness analysis would not be appropriate because she is only interested in one particular program. A cost-utility analysis is also not appropriate because quality of life, while included in the project, is not the focus of her project. A cost-benefit analysis could be appropriate. A cost-benefit analysis requires that both the interventions and outcomes be valued in monetary units. She can determine the direct medical and/or nonmedical costs for each patient from data captured by her HMO. The HMO is very interested in costs, both those to implement the service and those it may save as a result. Cynthia decides that the most understandable analysis to present to the HMO is a cost-benefit analysis. 

In order to use commercial reagents in a drug development program, it was important to negotiate and plan with the kit supplier to assure consistency of the Ab reagents, and that sufficient quantities would be reserved. Method robustness included the pre-study validation tests with a second lot of the capture Ab, three analysts, and three batches of radioiodinated detector Ab. Method robustness was further demonstrated by in-study validation, with four additional analysts performing sample analysis using 12 batches of radioiodinated detector Ab over a time span of approximately three years. 

After the image has been successfully captured, the contents of the buffer memory may be mapped onto the address space of the Unibus of a PDP11/04 minicomputer for quantitive analysis, via a group of programs (SIM-1) (7). Approaches to analysis available to us include least squares fitting (5), eigen analysis (3). and... 

After the initial programming of the state-of-the-art data collector units, a display window on the module provides a description of each piece of equipment on the surveillance route in sequence. The vibration inspector, prompted by the instrument readout, walks up to the operating equipment described on the display and thrusts a probe on the indicated bearing or other data point. When the analyst presses a button, the module captures the vibration level and any required analysis data. The data collector automatically identifies troubled sets based upon preset alarm values and collects spectrum data. Once the data col-... 

Step four in the interfacing operation is the use of computer software to communicate with a device and to capture the information it sends for analysis and display. This can be done at a basic level using machine language or higher programming tools such as Visual Basic, but increasingly this capability is provided by manufacturers of instraments, measurement systems, or interface boards. This relieves the user of much of the effort in interfacing devices and allows efficient and easy set up of different experiments typically done in physical chemistry laboratories. As illustration, we consider two examples of measurement approaches that can be used in a number of the experiments in this book.
