    Peensoole barjääri läbilaskvus, seda mõjutada võivad tegurid ja selle määramise meetodid

    Toitainete omandamise seisukohalt on peensool inimkeha olulisim elund. Peensoole läbilaskvus tähendab igasuguste ainete võimet läbida epiteeli, isegi kui neile vastav transpordivalk puudub. Kuivõrd peensoole läbilaskvus on dünaamiline, suuresti mikrobioomist sõltuv ja mitmete haigusseisundite sümptomaatika kujundaja, on oluline osata seda usaldusväärselt määrata ning tulemusi teaduspõhiselt tõlgendada. Selleks kasutatakse eelkõige in vivo meetodeid, näiteks sahhariidide manustamisel põhinevaid aktiivseid teste. Alternatiivina on võimalik määrata biomarkerite taset veres, uriinis või roojas. Kasutatavad markerid on näiteks kalprotektiini, zonuliini, tsitrulliini ja klaudiin-3 tasemed, kuid nende puuduseks jääb madal spetsiifilisus, vähene tõenduspõhisus või testidest tulenevad ebatäpsused määramisel

    Aim: This retrospective study was performed to determine the vascular endothelial growth factor (VEGF) expression in cervical cancer cells, and to examine its correlation with clinicopathologic characteristics and survival of patients. Methods: Seventy-five paraffinembedded primary tumors were stained immunohistochemically for VEGF expression, which was analysed semiquantitatively. Results: The significant correlation between VEGF expression and stages of disease, as well as pelvic lymph node metastasis was observed. There were determined a negative correlations between VEGF expression in tumor cells and both overall and disease-free survival. Conclusion: VEGF expression in human cervical cancer may be used as a diagnostic parameter in the clinic. Our results are in accordance with literature data showing association of VEGF overexpression in tumor with a poorer patient survival

    Meditsiiniline immunoloogia Eestis. Arengutendentse ja saavutusi kuni 1980. aastateni

    Get PDF
    Ajaloolises ülevaates on käsitletud immunoloogiateadmiste kujunemist viimase kahe ja enama sajandi jooksul kuni 1990. aastateni. Nii nagu mujalgi, oli nende teadmiste areng esmajärjekorras tihedalt seotud mikrobioloogia ning nakkushaiguste profülaktika ja ravimeetodite arenguga. Hiljem immunoloogia uurimis- ja rakendusvaldkonnad laienesid ning alates 1970. aastatest tehti Eestis juba rohkesti allergia, autoimmuunsuse, infektsiooni ja vähiimmunoloogia uurimistööd. Sel ajal oli üheks oluliseks verstapostiks Eesti Immunoloogide Seltsi asutamine 1984. aastal.Eesti Arst 2016; 95(8):523–52

    Bile-tolerant Helicobacter species such as Helicobacter pullorum, Helicobacter bilis, and Helicobacter hepaticus are associated with hepatic disorders in animals and may be involved in the pathogenesis of chronic liver diseases (CLD) in humans. Antibody responses to cell surface proteins of H. pullorum, H. bilis, and H. hepaticus in serum samples from patients with CLD, a randomized population group, and healthy blood donors were evaluated by using enzyme linked immunosorbent assay (ELISA). The results were compared with the antibody responses to Helicobacter pylori. For analysis of a possible cross-reactivity between bile-tolerant Helicobacter species and H. pylori, sera from a subpopulation of each group were absorbed with a whole-cell extract of H. pylori and retested by ELISA. Results before absorption showed that the mean value of the ELISA units for H. pullorum was significantly higher in patients with CLD than in healthy blood donors (P = 0.01). Antibody reactivity to cell surface protein of H. hepaticus was also significantly higher in the CLD patients than in the healthy blood donors and the population group (P = 0.005 and P = 0.002, respectively). Following the absorption, antibody responses to H. pullorum decreased significantly in all three groups (P = 0.0001 for CLD patients, P = 0.0005 for the population group, and P < 0.0001 for the blood donors), indicating that cross-reactivity between H. pylori and other Helicobacter spp. occurs. The antibody responses to H. hepaticus and H. bilis in CLD patients remained high following absorption experiments compared to ELISA results before absorption. The significance of this finding requires further investigations

    Češki pravni povjesničar Karel Kadlec i Hrvat Baldo Bogišić bili su dobri stari prijatelji i mnogo su se dopisivali nastavljajući time tradiciju hrvatsko-čeških kulturnih i znanstvenih veza. Njihovo prijateljstvo bilo je tipično prijateljstvo dvaju znanstvenika iz druge polovice i kraja XIX. st. kad su se otvarale knjižnice, kad je poštanska služba postala bolja, tako i promet pa su znanstvenici češće putovali. Baldo Bogišić je putovao i boravio u inozemstvu više od ijednog drugog hrvatskog znanstvenika. On je napisao na tisuće pisama, Kadlecu i drugima. S Kadlecom je izmjenjivao publikacije, znanstvene spoznaje. Sve je bilo motivirano slavenskom uzajamnošću, pojmom koji je stvorio Jan Kollar, koji je čak i došao u Zagreb.Baldo Bogišić und Karel Kadlec, beide Rechtshistoriker waren langjährige Freunde und wechselten oft und gerne Briefe, in denen sie die Fragen ihrer Forschungsarbeiten besprachen. Ihr Briefwechsel ist ein bedeutendes Kapitel der verzweigten Beziehungen kroatischer und tschechischer Intellektueller im 19. und zu Beginn des 20. Jh. Ein weiterer Briefschreiber an Kadlec war der bedeutende südkroatische Archäologe don Frane Bulić, der aber Forschungen von Kadlec bemängelte
