a1_Cíle. 1. popsat originální verzi Revised - Illness Perception Questionnaire (Moss-Morris et al., 2002), 2. popsat překlad, administrování a způsob vyhodnocení české verze IPQ-R-CZ, 3. charakterizovat její psychometrické vlastnosti, 4. diskutovat její vlastnosti a porovnat je s překlady do 9 národních jazyků. Česká verze respektuje strukturu originální verze: A – zdravotní obtíže pacienta, B – pacientovo pojetí své nemoci, C – pacientovy názory na příčiny své nemoci. Soubor a podmínky. IPQ-R-CZ byl administrován souboru 345 hospitalizovaných pacientů ve věku od 16 do 88 let (M=53,0; SD=15,7). Údaje byly získány ve velké fakultní nemocnici i v menších městských nemocnicích na 12 typech klinických pracovišť; dominovala interna, chirurgie, neurochirurgie, plicní a psychiatrie. Statistická analýza. Popisné statistiky, analýza rozptylu, exploratorní a konfirmatorní faktorové analýzy a analýza vnitřní konzistence škál. Výsledky. Původní škály pojetí nemoci (část B) jsou v české verzi vnitřně konzistentní a dobře rozlišují mezi typy onemocnění, s minimálními genderovými rozdíly. Faktorová struktura a validita je na rozdíl od originální verze nejasná a odlišná od anglického originálu. Platí to i pro percipované příčiny nemoci (část C). Limity studie. Platnost zjištění této studie (ve smyslu interní i externí validity) je omezena především nahodilým souborem pacientů a jejich onemocnění. Je zřejmé, že pacientovo pojetí nemoci souvisí s charakterem onemocnění. Dokládají to i výzkumy, které se pomocí jiného typu dotazníků zjišťují smysl nemoci z pohledu pacientů. Nezkoumalo se, nakolik jsou sledované faktory stabilní či proměnlivé v čase. Pro rutinní klinické používání je dotazník IPQ-R-CZ příliš dlouhý., a2_ V současné verzi je vhodný především k výzkumným účelům., Objectives. 1. To describe the original Revised - Illness Perception Questionnaire (Moss-Morris et al., 2002), 2. to describe the translation, administration and scoring of the Czech version, 3. to assess its psychometric properties, 4. to compare the findings with the translations to 9 other languages. The Czech version keeps the three-part structure of the original measure A- experienced symptoms (identity), B-illness perceptions, C- perceptions of causes of respondent’s illness. Sample and setting. IPQ-R-CZ was administered to 345 hospitalised patients (ages 16 to 88, M=53.0, SD=15.7) in large university hospitals and smaller local hospitals at 12 types of clinical workplaces, mostly internal medicine, surgery, neurosurgery, pulmonary, and psychiatry. Statistical analysis. Descriptive statistics, ANOVA, exploratory and confirmatory factor analyses, internal consistency of scales. Results. The original scales of illness perception (part B) internally consistent in the Czech version and discriminate among various types of illness with minimal gender differences. Factor structure and validity is unclear and substantially different from the original English version. The same applies to the perceived causes of illness (Part C). Study limitation. Both internal and external validity of this study are limited by the convenience sample of patients and their illnesses. It is clear that the patient’s illness perceptions and their dimensions are related to the nature of the illness itself. This is supported also by studies of the meaning of illness. Empirical data on the stability of the perceptions in time are not available. For routine clinical use the questionnaire is too long. In its current version it is suitable for research purposes predominantly., Jiří Mareš, Stanislav Ježek., and Obsahuje seznam literatury
Muga silkworm (Antheraea assamensis Helfer) is endemic to Assam and adjoining areas in North-Eastern India, and naturally produces golden silk. From time immemorial, many ethnic and tribal groups have produced muga silk. Muga silkworms are mostly wild unlike the mulberry silkworm, which is completely domesticated. The muga silkworm is a single species with little genetic variation among populations, survives harsh climatic conditions and is subject to various diseases, pests and predators. Due to the high incidence of disease and natural enemies, and variations in climatic conditions, the production of muga silk has recently declined dramatically. In order to improve the productivity of this silkworm it is important to have a better knowledge of both its host plants and biology. Lack of knowledge of its genetics and host plants is a major bottleneck. This paper reviews various aspects of muga silkworm culture, including the availability of different populations, and methods used to select for improvement in survival, cocoon yield, disease resistance, conservation and egg production., Amelendu Tikader, Kunjupillai Vijayan, Beera Saratchandra., and Obsahuje seznam literatury
A nonpigmenting strain of Serratia marcescens Bizio isolated from dead and apparently diseased wild apple maggot flies, Rhagoletis pomonella (Walsh), was shown to be pathogenic to healthy apple maggot flies upon ingestion. The microorganism was detected in live adult alimentary canal organs four days post ingestion but produced death in some flies within 24 h when flies fed on a cell concentration of 4.7 × 104 cfu/ml and within 8 h when flies fed on filter-sterilized culture medium that previously contained a 21 h culture of S. marcescens. Increasing the cell concentration 10,000 fold did not lead to an increased rate of kill. Young flies (7-10 days old) were more susceptible to infection leading to death than were older flies (21-28 days old). The potential use of S. marcescens cells as control agents against apple maggot flies is negated by their pathogenicity to vertebrates; however, the potential use of toxic compounds produced by this strain of S. marcescens is discussed.
