A novel synthesis of octahydropyrido[3,2-c]carbazole framework of aspidospermidine alkaloids and a combined computational, FT-IR, NMR, NBO, NLO, FMO, MEP study of the cis-4a-Ethyl-1(2hydroxyethyl)-2,3,4,4a,5,6,7,11c-octahydro-1H-pyrido[3,2-c] carbazole
(ELSEVIER SCIENCE BV, 2018)In this study, we performed a novel synthesis of the octahydropyrido[3,2-c]carbazole derivative 6 from 1 in five steps with a 34% overall yield. We also developed a unique compound 2 by a cyclization reaction from the ... -
Novel type ketone-substituted metallophthalocyanines: synthesis, spectral, structural, computational and anticancer studies
(ROYAL SOC CHEMISTRY, 2017)This work reports on the synthesis and characterization of phthalocyanines (M = Cu(II) (2), Zn(II) (3) In(III) (4) and Co(II) (5)) peripherally tetra-substituted with 1-(4-hydroxyphenyl) propan-1-one. Confirmation of the ... -
Novel variant syndrome associated with congenital hepatic fibrosis
(BAISHIDENG PUBLISHING GROUP INC, 2015)Congenital hepatic fibrosis is part of many different malformation syndromes, of which oculo-encephalohepato-renal syndrome is the most common. These syndromes largely overlap, and so accurate classification of individual ... -
Nozokomiyal enterokok infeksiyonları

Nötropenik ateşli hastalarımızda meropenem ile Seftazidim-amikasin kombinasyonunun etkinliklerinin karşılaştırılması
(2004)Amaç: Enfeksiyonlar, kanserli immünsuprese çocuklarda mortalite ve morbiditenin en büyük nedenidir. Nötropenik ateşli hastalarda ampirik antibiyotik tedavisi hemen başlanmalıdır. Bu çalışmada febril nötropenik kanserli ... -
NSEM: Novel Stacked Ensemble Method for Sentiment Analysis
(IEEE, 2018)Today, people often share their ideas, opinions and feelings through forums, social media sites, blogs and similar platforms. For this reason, access to these data has become very easy. Increase in the number of shares ... -
The nucleophilicity equalization principle and new algorithms for the evaluation of molecular nucleophilicity
(ELSEVIER SCIENCE BV, 2016)In this work, we have attempted to explore whether the nucleophilicity equalization principle can be conceived analogous to the well-established electronegativity, hardness, and electrophilicity equalization principle. ... -
