Colletes anchusae Noskiewicz, 1924 and C. wolfi Kuhlmann, 1999 (Colletidae) are closely related bee species with vicariant distributions, the former occurring in east and southeast Europe and Turkey, the latter restricted to the Italian peninsula. Microscopical analysis of scopal pollen revealed that in Europe both species are monolectic collecting pollen exclusively from flowers of Cynoglottis barrelieri (All.) Vural & Kit Tan (Boraginaceae). In Turkey, C. anchusae possibly visits also Cynoglottis chetikiana Vural & Kit Tan. The distributions of the two bee species and of Cynoglottis coincide. The females of both Colletes species are equipped with stout, curved bristles on their foretarsi used for scraping pollen out of the narrow flower tube of Cynoglottis. Compared to other European species of Colletes the foretarsi of C. anchusae and C. wolfi are shortened, presumably an adaptation to the short corolla tube of their host plant.
Incidence solidních nádorů v naší populaci stoupá s věkem. Nejfrekventnějšímí nádory ve stáří jsou tumory prsu, kolon a rekta, pankreatu a žaludku. Extraperitoneální mezenchymálni nádory se vyskytují naopak zřídka. Chirurgická léčba u solidních nádoru je stále nejdůležitější a nejefektivnější léčebnou modalitou. Míra rizika operační léčby u starých lidí je dána řadou faktorů, které lze cíleně ovlivnit. Staří lidé by tedy pro svůj kalendářní věk neměli být zbaveni možnosti kuraťivní chirurgické léčby., The incidence of solid tumours in our population increases with age. The most frequent tumours in old age are the tumours of breast, colon and rectum, of pancreas and stomach. On the contrary extraperitoneal mesenchymal :umours are rare. Surgical treatment of solid tumours is the most important and most efective treatment modality. The risk of surgical treatment in the elderly is influenced by a variety of factors, which can be specifically influenced. Elderly )eople should not be denied surgical treatment because of their calendar age., Pavel Jandík, J. Mergancová, D. Nikolov Hadži, Lit: 12, and Souhrn: eng
Nitric oxide (NO) is an important endogenous mediator with significant role in the respiratory system. Many endogenous and exogenous factors influence the synthesis of NO and its level is significantly changed during the inflammation. Analysis of nasal nitric oxide (nNO) is not validated so far as the diagnostic method. There is a lack of reference values with possible identification of factors modulating the nNO levels. In healthy adult volunteers (n=141) we studied nasal NO values by NIOX MINO® (Aerocrine, Sweden) according to the recommendations of the ATS & ERS. Gender, age, height, body weight, waist-to-hip ratio, FEV1/FVC, PEF and numbers of le ukocytes, eosinophils, basophils and monocytes were studied as potential variables influencing the levels of nNO. The complexity of the results allowed us to create a homogenous group for nasal NO monitoring and these data can be used further as the reference data for given variables. Because of significant correlation between nNO and exhaled NO, our results support the "one airway - one disease" concept. Reference values of nasal NO and emphasis of the individual parameters of tested young healthy population may serve as a starting point in the non-invasive monitoring of the upper airway inflammation., M.
