    • The Oxidative Stress May be Induced by the Elevated Homocysteine in Schizophrenic Patients 

      Dietrich-Muszalska, Anna; Malinowska, Joanna; Olas, Beata; Głowacki, Rafal; Bald, Edward; Wachowicz, Barbara; Rabe-Jabłońska, Jolanta (Springer, 2012)
      The mechanisms of oxidative stress in schizophrenic patients are not fully understood. In the present study, we investigated the effect of elevated level of homocysteine (Hcys) on some parameters of oxidative stress, namely ...
    • THE REACTION OF TETRAMETHYLSILANE WITH BORON TRIBROMIDE 

      Lewkowski, Jarosław; Vaultier, Michel (Walter de Gruyter (Previously published by Freund Publishing House Ltd.), 2001-12-01)
      The reaction of tetramethylsilane with boron tribromide in deuterochloroform in ambient temperature or at 40°C led to bromotrimethylsilane (3) and to dibromomethylborane (4). Identity of products was confirmed by NMR ...
    • The substituent effect on benzene dications 

      Palusiak, Marcin; Domagała, Małgorzata; Dominikowska, Justyna; Bickelhaupt, F. Matthias (RSC Publishing, 2014-01-03)
      It was recently postulated that the benzene ring and its 4n + 2 p-electron analogues are resistant to the substituent effect due to the fact that such systems tend to retain their delocalized character. Therefore, the 4n ...
    • Treatment of chronic hemodialysis patients with low-dose fenofibrate effectively reduces plasma lipids and affects plasma redox status 

      Makówka, Agnieszka; Dryja, Przemysław; Chwatko, Grażyna; Bald, Edward; Nowicki, Michał (BioMed Central, 2012)
      Dyslipidemia is common in chronic hemodialysis patients and its underlying mechanism is complex. Hemodialysis causes an imbalance between antioxidants and production of reactive oxygen species, which induces the oxidative ...
    • Versatile Phase Transfer Method for the Efficient Surface Functionalization of Gold Nanoparticles: Towards Controlled Nanoparticle Dispersion in a Polymer Matrix 

      Ranoszek-Soliwoda, Katarzyna; Girleanu, Maria; Tkacz-Szczęsna, Beata; Rosowski, Marcin; Celichowski, Grzegorz; Brinkmann, Martin; Ersen, Ovidiu; Grobelny, Jaroslaw (Hindawi Publishing Corporation, 2016)
      In electronic devices based on hybrid materials such as nonvolatile memory elements (NVMEs), it is essential to control precisely the dispersion of metallic nanoparticles (NPs) in an insulating polymer matrix such as ...
    • Voltammetric behaviour and quantitative determination of pesticide iminoctadine 

      Smarzewska, Sylwia; Metelka, Radovan; Guziejewski, Dariusz; Skowron, Monika; Skrzypek, Slawomira; Brycht, Mariola; Ciesielski, Witold (Royal Society of Chemistry, 2014)
      Iminoctadine (IOD) was determined in spiked river water samples by square wave voltammetry (SWV) using a cyclic renewable silver amalgam film electrode (Hg(Ag)FE). It was found that the compound can act as an electrocatalyst. ...
    • Who Receives Home-Based Perinatal Palliative Care: Experience from Poland 

      Korzeniewska-Eksterowicz, Aleksandra; Przysło, Łukasz; Kędzierska, Bogna; Stolarska, Małgorzata; Młynarski, Wojciech (Hindawi Publishing Corporation, 2013)
      The current literature suggests that perinatal palliative care (PPC) programs should be comprehensive, initiated early, and integrative. So far there have been very few publications on the subject of home-based PC of ...
    • Why 1,2‑quinone derivatives are more stable than their 2,3‑analogues? 

      Szatylowicz, Halina; Krygowski, Tadeusz M.; Solà, Miquel; Palusiak, Marcin; Dominikowska, Justyna; Stasyuk, Olga A.; Poater, Jordi (Springer Berlin Heidelberg, 2015-02-25)
      In this work, we have studied the relative stability of 1,2- and 2,3-quinones. While 1,2-quinones have a closed-shell singlet ground state, the ground state for the studied 2,3-isomers is open-shell singlet, except ...
    • Zwitterionic pyridinium derivatives of [closo-1-CB_9H_10]− and [closo-1-CB_11H_12]− as high Δε additives to a nematic host 

      Pecyna, Jacek; Pociecha, Damian; Kaszyński, Piotr (Royal Society of Chemistry, 2013)
      Substituted closo-carbaborate–pyridinium zwitterions were prepared in 35–50% yield by reacting 1-amino-closo-1-carbaborates with 4-alkoxypyrylium triflates. Two of the new materials, 1[6]d and 2[10]b, exhibit a high ...
