characterization and in vitro anti-cancer evaluation of itaconic acid based randon copolyester.

The present study deals with the synthesis and characterization of an aliphatic copolyester, poly [butylene fumarate-co-butylene itaconate] (PIFB) copolymer was obtained from itaconic acid, fumaric acid, and 1,4-butanediol using titanium tetraisopropoxide (TTiPO) through a two step process of transesterification and melt polycondensation. The synthesized aliphatic random copolyester was characterized with the help of FT-IR, 1 H-NMR, 13 C-NMR, viscosity measurements, Gel Permeation Chromatography (GPC) and X-ray diffraction (XRD) analysis. Thermal properties have been analyzed using thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC). Hydrolytic degradation studies were carried out in acid and alkaline regions of various pH values. The synthesized copolymer was subjected to in vitro anticancer activity studies against human breast cancer (MCF-7) cell line

Simultaneous Insertion of a Left Ventricular Assist System and Repair of an Ascending Aortic Dissection

Operative methods for repairing ascending aortic dissections and for implanting left ventricular assist systems have been thoroughly presented in the medical literature. Only a few reports, however, describe the concomitant performance of these procedures in 1 patient. We report the repair of an acute ascending aortic dissection with simultaneous placement of a long-term left ventricular assist system. One week earlier, the patient had undergone emergent coronary artery bypass grafting and short-term postcardiotomy ventricular assistance when he could not be weaned from cardiopulmonary bypass. By creating a graft-to-graft anastomosis on the bench during cooling of the patient on cardiopulmonary bypass, we were able to shorten to 21 minutes the period of hypothermic circulatory arrest required during ascending aortic dissection repair. The procedures were completed successfully. However, the patient developed pneumonia and sepsis during his extended hospital stay and died of multiorgan failure 5 weeks postoperatively

Ekstrakcja barwników z Petrocarpus santalinus i barwienie naturalnych włókien przy użyciu różnych zapraw farbiarskich

Aqueous extraction of natural dyes from Petrocarpus santalinus tree wood and dyeing of the following natural fibres: banana fibre, screw fine fibre, pineapple fibre, sisal fibre, korai and palm leaf using various mordants to fix the colour in the fibre materials were performed. Salt, sodium bicarbonate, oxalic acid, tannic acid, ferrous ammonium sulphate, stannous chloride (tin metal powder), alum and tamarind (Tamarindus indica) were used as a mordant for the dying of the natural fibres. Petrocarpus santalinus dye was effectively dyed on natural fibres using different mordants, producing different colours like tomato, maroon, orange red, chocolate, brown, quarry red, black, brick red, tile red, terra colla, sunbaked clay, gray, brick red, victorian red, firebrick, brown, crimson and orange, using these mordants.W artykule omówiono wykonanie wodnej ekstrakcji naturalnych barwników z drzewa Petrocarpus santalinus oraz barwienie włókien naturalnych, m.in. bananowca, ananasa, sizalu, korai i liści palmowych przy zastosowaniu różnych zapraw farbiarskich, których użycie miało na celu utrwalenie koloru w materiałach włóknistych. Jako zapraw farbiarskich użyto soli, wodorowęglanu sodu, kwasu szczawiowego, kwasu garbnikowego, siarczanu żelazowo-amonowego, chlorku cyny (proszek cyny metalicznej), ałunu i tamaryndowca (Tamarindus indica). Włókna naturalne skutecznie zabarwiono barwnikiem Petrocarpus santalinus przy użyciu różnych zapraw uzyskując różne kolory takie jak: pomidorowy, bordowy, pomarańczowy, czerwony, czekoladowy, brązowy, czarny, czerwony ceglany, terra colla, glinka opalana, szara, ceglastoczerwona, wiktoriański czerwony, ognisty, brązowy, szkarłatny i pomarańczowy
