The species Tinodes antonioi, a new species in the fauna of Croatia, was determined in northern Istria. The paper provides information about T. antonioi in Croatia (DNA barcode data, period of the ...finds, localities of the finds, numbers of males and females collected) as well as the biodiversity and distribution of the Tinodes genus in Croatia. A reference is made to the species endemic in Croatia, Tinodes andrasi, established to date at only one site in the south of Croatia (Konavle, Dalmacija).
Na području jadranskih otoka (Cres, Krk, Pag, Hvar) utvrđeno je do sada 13 vrsta Trichoptera iz 11 rodova i 8 porodica. Novija istraživanja provedena su na otocima Cresu, Krku i Pagu u kojima je ...prikupljeno 329 adultnih oblika Trichoptera s 10 vrsta iz 8 rodova i 6 porodica. Najdominantnije vrste bile su Ecnomus tenellus s 235 prikupljenih primjeraka (Krk i Cres) i Leptocerus tineiformis (Krk) s 51 prikupljenim primjerkom, a samo s jednim primjerkom zabilježene su vrste Stenophylax mitis (Cres) i Mystacides azurea (Krk). Najveći broj vrsta utvrđen je na otoku Krku (7), a najmanji na otoku Pagu (2). Faunistički najzanimljiviji je nalaz vrste Stenophylax mitis McL. koja je ovim istraživanjima utvrđena po prvi puta u fauni Hrvatske.
U ovome radu prikazujemo: dvije nove vrste zabilježene u fauni Hrvatske iz porodice Hydroptilidae (Hydroptila simulans Mosley, Orthotrichia costalis Curtis), prikaz DNA barkodiranja tulara u ...Nacionalnom parka Krka te osvrt na faunistički najzanimljivije vrste utvrđene tijekom ovih istraživanja. Faunistički najzanimljiviji su nalazi sljedećih vrsta: Hydropsysche mostarensis Klapálek, Hydroptila simulans Mosely, Hdroptila forfcipata Eaton, Orthotrichia costalis Curtis i Tinodes pallidulus McLachlan. Vrsta Oecetis notata Rambur nazanimljivija je s taksonomskog aspekta. U ovim istraživanjima metoda DNA barkodiranja pokazala se kao vrlo korisna u determinaciji vrlo malih i morfološki sličnih vrsta iz porodice Hydroptilidae te ženki iz porodice Psychomyiidae.
Vrsta Tinodes antonioi, kao nova u fauni Hrvatske, zabilježena je po prvi puta u sjevernoj Istri. U radu se daju informacije o T. antonioi u Hrvatskoj (DNA barkod podaci, periodi nalaza, lokaliteti ...nalaza, broj prikupljenih mužjaka i ženki), kao i bioraznolikost i rasprostranjenost roda Tinodes u Hrvatskoj. Daje se osvrt i na endem Hrvatske, Tinodes andrasi, zabilježen samo na jednom lokalitetu u Hrvatskoj (Konavle, Dalmacija).
Glioblastoma is the most frequent, the most malignant and the best vascularised primary brain tumor. Substantial evidence suggests that IGFBP-2 (insulin-like growth factor binding protein) may play a ...significant role in the development and progression of various types of cancer, including the anaplastic progression of astroglial tumors. The correlation of IGFBP-2 and VEGF over-expression in diffuse gliomas and strong IGFBP-2 immunostaining and co-expression with VEGF in the cells of pseudopalisading necrosis suggests the induction of IGFBP-2 expression by hypoxia and/or possible involvement of its protein product in angiogenesis. The aim of this study was to analyze the expression of IGFBP-2 and the relationship between the IGFBP-2 expression, extent of bizarre angiogenesis and the presence of pseudopalisades. The prognostic impact of these variables was estimated, as well. Our results revealed that most glioblastoma (75%) express IGFBP2 and that IGFBP2 expression was associated with the presence of pseudopalisading necrosis as well as extensive bizarre angiogenesis. IGFBP-2 immunoreactivity in more than 5% of tumor cells and the presence of pseudopalisading necrosis were prognostically significant in univariate analysis (p=0.034) while in multivariate analysis only a patient’s age and the presence of pseudopalisades remained statistically significant (p=0.004). The results of our study showed the association of IGFBP-2 expression in glioblastoma with pseudopalisades and bizarre angiogenesis thus confirming on morphological grounds presumed induction of this gene under hypoxic conditions and its possible role in angiogenesis.
