PMID: 26617679
Hosp Chron. 2015;10(2):91-98.

INTRODUCTION: The purpose of this electrophysiological neuroimaging study was to provide a deeper mechanistic understanding of both olanzapine and risperidone pharmacodynamics relative to gender. In doing so, we age-matched 22 men and women and evaluated their resting-state EEG recordings...

PMID: 26609422
Brain (Bacau). 2014 Dec;5(1):5-15.

INTRODUCTION: The purpose of this investigatory neuroimaging analysis was done to better understand the pharmacodynamics of Lithium by isolating the norepinephrine pathway in the brain. To accomplish this, we compared patients with Bipolar Disorder treated with Lithium to patients...

The New TLC Method for Separation and Determination of Multicomponent Mixtures of Plant Extracts.

Journal of analytical methods in chemistry

Matysik E, Woźniak A, Paduch R, Rejdak R, Polak B, Donica H.
PMID: 26981317
J Anal Methods Chem. 2016;2016:1813581. doi: 10.1155/2016/1813581. Epub 2016 Feb 14.

The new mode of two-dimensional gradient thin layer chromatography (MGD-2D TLC) has been presented. Short distance development of sample in the first dimension leads to formation of the preconcentrated narrow zones. They are consecutively separated in the second dimension...

Manufacturing and investigation of physical properties of polyacrylonitrile nanofibre composites with SiO2, TiO2 and Bi2O3 nanoparticles.

The aim of this study was to produce nanocomposite polymer fibres, consisting of a matrix of polyacrylonitrile (PAN) and a reinforcing phase in the form of SiO2/TiO2/Bi2O3 nanoparticles, by electrospinning the solution. The effect of the nanoparticles and the...

The aberrant overexpression of vimentin is linked to a more aggressive status in tumours of the gastrointestinal tract.

Prz Gastroenterol. 2015;10(1):7-11. doi: 10.5114/pg.2014.47502. Epub 2015 Jan 14.

Vimentin is an intermediate filament protein normally expressed in cells of mesenchymal origin, e.g. myofibroblasts, chondrocytes, macrophages, and endothelial cells. The expression of vimentin, which has been thought of as the main mesenchymal marker, is also detected in tumour...

Cyclic voltammetric determination of adrenaline in the presence of copper(II) ions.

Talanta

Przegalinski M, Matysik J.
PMID: 18962824
Talanta. 1980 Nov;27(11):920-2. doi: 10.1016/0039-9140(80)80156-1.

Low concentrations of adrenaline (10(-5)-10(-4)M) have been found to give rise to quite marked current peaks in the cyclic voltammograms recorded for ammoniacal solutions containing a copper(II) salt at around 10(-4)M. Fast sweep-rates (20 V/sec) are generated by a...

Comparison of the performance characteristics of two tubular contactless conductivity detectors with different dimensions and application in conjunction with HPLC.

Analytical and bioanalytical chemistry

Mark JJ, Coufal P, Opekar F, Matysik FM.

Two tubular capacitively coupled contactless conductivity detection (C(4)D) cells with different geometric dimensions were evaluated with regard to their main analytical characteristics under non-separation and separation conditions in conjunction with liquid chromatography. A comparison of the performance of the...

Dendritic cells (DC) are now recognized as major players in the control of immune responses (1), since they direct both the quality and the extent of the adaptative response. Thus, DC represent a very appropriate means for the manipulation...

Exploring Chromophore-Binding Pocket: High-Resolution Solid-State H-C Interfacial Correlation NMR Spectra with Windowed PMLG Scheme.

Applied magnetic resonance

Appl Magn Reson. 2012 Feb;42(1):79-88. doi: 10.1007/s00723-011-0196-6. Epub 2011 Feb 11.

High-resolution two-dimensional (2D) (1)H-(13)C heteronuclear correlation spectra are recorded for selective observation of interfacial 3-5.5 Å contacts of the uniformly (13)C-labeled phycocyanobilin (PCB) chromophore with its unlabeled binding pocket. The experiment is based on a medium- and long-distance heteronuclear...

PMID: 20306181
Anal Bioanal Chem. 2010 Jun;397(3):961-5. doi: 10.1007/s00216-010-3586-y. Epub 2010 Mar 20.

Capillary electrophoretic separations performed in short capillaries under high field strengths have recently emerged as a promising alternative to chip-based separations. However, the injection and detection approaches have to be adapted appropriately to enable high-throughput determinations. This paper addresses...
