A theory of color coding is presented which is applicable to both the Prevost-Fechner-Benham subjective color and the color sensation arising from retinal stimulation by a narrow band of the light spectrum. The primary features of the theory are: (1) three types of photoreceptors which are present in the retina in approximately equal numbers; (2) lateral inhibitory interaction among the photoreceptors; (3) a fixed temporal or serial order in which the relative response of each photoreceptor type is processed; and (4) an integration/interaction period of approximately 100 msec. On the basis of the theory, the operations for eliciting specific subjective colors are successfully predicted.

Ethanol Stability

SummaryThe ethanol (EtOH) stability of skim milk and the stability towards aggregation of casein micelles diluted into ethanolic buffer solutions were compared using data obtained from previously published experiments. Differences in absolute stability and in relative response were observed when Ca2+ level and pH were adjusted, the buffer system results lying below those from skim milk in both cases. Increasing the ionic strength of skim milk adjusted to pH 7·0 lowered its EtOH stability whereas increasing the ionic strength of the diluting buffer increased the stability of the casein micelles. The hypothesis is put forward that the differences are due to the simultaneous precipitation of Ca phosphate when EtOH is added to skim milk. This draws calcium from the caseinate sites of the micelle, counteracting the destabilizing effects of the EtOH towards the micelle. Such removal and the consequent restructuring are kinetically controlled and micellar precipitation in skim milk finally occurs when the micellar coagulation time falls within the time scale of the restructuring reactions.

Abstract Background Immunologic background of vitiligo, role of vitamin D on its pathogenesis, role of NB-UVB on its treatment and its stimulatory effect NB-UVB on VDR expression are challenging area of research. The current study will focus on evaluating the effect of NB-UVB on serum and tissue level of vitamin D in vitiligo patients and correlating it with the degree of improvement. Aim of the study The aim of the present study is to evaluate and compare the serum and tissue vitamin D level in vitiligo patients before and after NB- UVB therapy and correlate them together and with the degree of improvement. Patients and methods A case-control study included 16 vitiligo patients and 16 age and sex matched healthy controls. All patients will be examined by one dermatologist (demonstrating the extent of depigmentation according to rule of nines), and photographs will be taken before and after phototherapy to be evaluated by two different dermatologists to document the extent of repigmentation. Estimation of serum level of vitamin D by ELISA Results Five of the 15 patients achieved more than 55% repigmentation; the mean duration of disease was 13 months. The remaining 10 patients had 30% - 40% repigmentation.

Objectives Compliance with standards in designing information systems leads to better utilization and ease of use for users. In this study, the compliance of a widely used hospital information system (HIS) with ISO 9241 part 12 was assessed. Methods This applied research is a descriptive, cross-sectional study in which the HIS of 8 hospitals affiliated with Kerman University of Medical Sciences was evaluated based on ISO 9241 part 12. Data were collected by using ISO 9241/12 checklist. The data was analyzed in SPSS 16 using descriptive statistics. Results The analysis of data showed that the total compliance of the software with the ISO 9241/12 was 72%. The compliance of the software based on different groups of recommendations was 79% with Organization of information, 91% with Graphic objects, and 58% with Coding techniques. Compliance with different subgroups of ISO recommendations ranged from 28% related to “color coding” in coding techniques to 97% related to “General recommendation for graphical objects” in Graphic objects. Conclusion According to this study, the design of a widely used HIS has fairly good compliance with the standard but still suffers from some problems. Considering the role of accurate, valid and timely information in management of the hospitals, and the difficulty of system optimization after implementation, it is necessary that software developers follow existing standards when designing health information systems.
