The Participatory Process: Producing Photoliterature

This note describes a step-by-step process for involving learners in the development, production and evaluation of various types of photoliterature including fotonovellas. Technical information on photographic techniques is presented to assist educators in the participatory process. In this manual, we have given suggestions on how to combine participation and the development of photo-literature. First, we consider the rationales for learner-produced materials. In the second section we discuss the participatory process and focus on the relationship of the facilitator (probably you) to the participants and how the facilitator can enhance or inhibit the process. The third section is designed to answer the technical questions a facilitator may have regarding how to put a fotonovela together. The technical aspects are about the same for all types of photo-literature. Participation is difficult to discuss and understand in a vacuum, and, therefore, we have integrated participatory process boxes throughout the technical section to give specific suggestions on how to increase participation in the context of specific technical problems. In the fourth section we discuss some considerations in summative evaluation, following in the last section with an examination of some of the pros and cons of various photo-literature formats

Urinary cholesterol in cancer screening

Cholesterol determinations in morning urine samples were taken in 235 selected patients with a positive test for microscopic hematuria. Values ranged from 0.2 to 76.0 mg (median 5.5) in 23 patients with urologic malignancies and from 0.1 to 33.4 mg (median 1.1) in 38 patients with various benign diseases of the kidney or urogenital tract. In the 28 patients with urinary tract infections and 146 subjects without evidence of disorders of the kidney and the urogenital system, urinary cholesterol excretion was usually normal (0.1 to 1.9 mg; median 0.35). Using 1.0 mg urinary cholesterol per morning urine as a cutoff point, sensitivity for urologic carcinomas is about 80 per cent with a comparable high specificity of 90 per cent. Therefore, subsequent measurements of urinary cholesterol in populations with microscopic hematuria could define two groups, one with high prevalence and one with low prevalence of urologic malignancies. The less complicated colorimetric instead of gas-liquid chromatographic determination of urinary cholesterol can be recommended as a screening test for urologic carcinomas in populations with microscopic hematuria

Laser-UV-microirradiation of interphase nuclei and posttreatment with caffeine: a new approach to establish the arrangement of interphase chromosomes

Laser UV microirradiation of Chinese hamster interphase cells combined with caffeine post-treatment produced different patterns of chromosome damage in mitosis following irradiation of a small area of the nucleus that may be classified in three categories: I) intact metaphase figures, II) chromosome damage confined to a small area of the metaphase spread, III) mitotic figures with damage on all chromosomes. Category III might be the consequence of a non-localized distortion of nuclear metabolism. By contrast, category II may reflect localized DNA damage induced by microirradiation, which could not be efficiently repaired due to the effect of caffeine. If this interpretation is right, in metaphase figures of category II chromosome damage should occur only at the irradiation site. The effect might then be used to investigate neighbourhood relationships of individual chromosomes in the interphase nucleus
