Abstract

fetched live from OpenAlex

CieÄž:UĹž pred časom sme uviedli, Ĺže prechodnĂŠ zvýťenie vnĂştrobunkovej koncentrĂĄcie Ca2+ v bunkĂĄch podobnĂ˝ch endotelu mĂ´Ĺže odrĂĄĹžaĹĽ priebeh endotelizĂĄcie na polyesterovej tepennej protĂŠze typu Arteknit Ra K®, implantovanej do aorty nečistokrvnĂ˝ch psov (Physiol Res 2002;51:217-20). V tejto ĹĄtĂşdii sme u tĂ˝chto psov po krĂĄtkodobej implantĂĄcii hodnotili včasnĂŠ vhojenie tepennĂŠho ĹĄtepu, t. j. jeho priechodnosĹĽ, morfolĂłgiu, endotelizĂĄciu a tromborezistenciu. MetĂłdy:Do aorty nečistokrvnĂ˝ch psov sme na vopred určenĂŠ obdobie v rozmedzĂ­ 48 hodĂ­n aĹž 6 mesiacov implantovali 12 protĂŠz typu Arteknit Ra K®. Vzorky vyňatĂŠho ĹĄtepu boli vyĹĄetrenĂŠ histologicky a skenovacou elektrĂłnovou mikroskopiou, analyzovanĂŠ na vychytĂĄvanie krvnĂ˝ch doĹĄtičiek a fibrinogĂŠnu, a zĂĄroveň aj na koncentrĂĄciu prostacyklĂ­nu (PGI2) a tromboxĂĄnu A2 (TXA2). VĂ˝sledky:V čase utratenia mali vĹĄetky ĹĄtepy neporuĹĄenĂş ĹĄtruktĂşru a 11 z nich vykazovalo vyhovujĂşcu rozmerovĂş stabilitu. Po 48 hodinĂĄch bola pozorovanĂĄ akĂştna, stredne zĂĄvaĹžnĂĄ zĂĄpalovĂĄ odpoveď, ktorĂş neskĂ´r nahradila chronickĂĄ zĂĄpalovĂĄ reakcia s obrovskĂ˝mi bunkami okolo cudzieho telesa, ktorĂŠ boli prĂ­tomnĂŠ aj po 6 mesiacoch. Po jednom mesiaci sa v obidvoch oblastiach anastomĂłzy vytvorili plĂĄty endotelu-podobnĂ˝ch buniek. StrednĂĄ časĹĽ ĹĄtepu bola po celĂ˝ čas trvania pokusu infiltrovanĂĄ organizovanou trombotickou matrix s ojedinele roztrĂşsenĂ˝mi endotelu-podobnĂ˝mi bunkami. Po troch mesiacoch doĹĄlo k biologickej erĂłzii luminĂĄlneho povlaku kolagĂŠnu a jeho rozklad neprekĂĄĹžal procesu hojenia. Tri aĹž ĹĄesĹĽ mesiacov po implantĂĄcii boli v hrudnĂ­ku pozorovanĂŠ na vonkajĹĄom povrchu ĹĄtepu zhrubnutĂŠ kapsule. V priebehu jednĂŠho aĹž ĹĄiestich mesiacov bolo vychytĂĄvanie krvnĂ˝ch doĹĄtičiek a fibrinogĂŠnu celkove nĂ­zke a pomerovĂŠ indexy PGI2 : TXA2 stanovenĂŠ vo vĹĄetkĂ˝ch častiach ĹĄtepu boli vyĹĄĹĄie ako 1. ZĂĄvery:PolyesterovĂĄ protĂŠza typu Arteknit Ra K® vykĂĄzala vyhovujĂşcu rozmerovĂş stabilitu, stredne vysokĂş biokompatibilitu a uspokojivĂŠ vhojenie v zmysle tkanivovĂ˝ch a zĂĄpalovĂ˝ch reakciĂ­.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
