Columnar mesomorphism of bi- and trinuclear Ni(II), Cu(II), and VO(II) cis-enamonoketone complexes with low symmetry.

Inorganic chemistry

Szydłowska J, Krówczyński A, Górecka E, Pociecha D.
PMID: 11196967
Inorg Chem. 2000 Oct 16;39(21):4879-85. doi: 10.1021/ic0000808.

New enaminoketone tetradentate bi- and trinuclear complexes creating columnar mesophases are reported. Various combinations of nickel, copper, or vanadyl ions were applied as metallic centers. Because of the bowlike structure of chelating centers and the low molecular symmetry (Cs)...

Dinuclear mesogens with antiferromagnetic properties.

Chemphyschem : a European journal of chemical physics and physical chemistry

Szydłowska J, Krówczyński A, Pociecha D, Szczytko J, Budzowski P, Twardowski A, Górecka E.
PMID: 20235112
Chemphyschem. 2010 Jun 07;11(8):1735-41. doi: 10.1002/cphc.200900880.

Herein, two new groups of isomeric bimetallic nickel(II) and copper(II) complexes containing pyrazine or pyrimidine rings are synthesized and examined. The complexes exhibit liquid-crystalline columnar phases in a broad temperature range. For the copper(II) complexes, super-exchange coupling between two...

Calamitic and discotic liquid crystalline phases for mesogens with triangular cores.

Soft matter

Szydłowska J, Krówczyński A, Górecka E, Pociecha D.
PMID: 31465073
Soft Matter. 2019 Sep 18;15(36):7195-7202. doi: 10.1039/c9sm01080g.

Mesogenic compounds having new triangular mesogenic cores containing salicylaldimine and enaminocarbonyl or barbituric moieties have been synthesized and their liquid crystalline, dielectric and optical properties have been studied. Appropriate substitution of such cores with various numbers of lateral chains...

Ultrasonographic assessment of articular cartilage of the femoral condyle in patients with an increased Q-angle.

Journal of ultrasonography

Kusiak M, Kawczyński A.
PMID: 30427128
J Ultrason. 2018;18(74):181-185. doi: 10.15557/JoU.2018.0027.

INTRODUCTION: The patella is a sesamoid for the quadriceps, which increases its power during knee extension and thus transfers considerable forces. The etiology of patellofemoral pain is multifactorial. In the absence of injury, the commonly accepted hypothesis is associated...

Integrating clinical and genetic approaches in the diagnosis of 46,XY disorders of sex development.

Endocrine connections

Kolesinska Z, Acierno J, Ahmed SF, Xu C, Kapczuk K, Skorczyk-Werner A, Mikos H, Rojek A, Massouras A, Krawczynski MR, Pitteloud N, Niedziela M.
PMID: 30496128
Endocr Connect. 2018 Dec;7(12):1480-1490. doi: 10.1530/EC-18-0472.

46,XY differences and/or disorders of sex development (DSD) are clinically and genetically heterogeneous conditions. Although complete androgen insensitivity syndrome has a strong genotype-phenotype correlation, the other types of 46,XY DSD are less well defined, and thus, the precise diagnosis...

Practical Use of the Navigate Pain Application for the Assessment of the Area, Location, and Frequency of the Pain Location in Young Soccer Goalkeepers.

Journal of human kinetics

Muracki J, Kumorek M, Kisilewicz A, Pożarowszczyk B, Larsen DB, Kawczyński A, Boudreau S.
PMID: 31666895
J Hum Kinet. 2019 Oct 18;69:125-135. doi: 10.2478/hukin-2019-0091. eCollection 2019 Oct.

Next to winning, minimizing injuries during training and matches is one of the primary goals of professional team sports games. Soreness and pain can be early indicators and risk factors for acute or long-term injuries. Monitoring pain intensity and...

Effect of a Support on the Properties of Zinc Oxide Based Sorbents.

Nanomaterials (Basel, Switzerland)

Chomiak M, Szyja BM, Jędrysiak M, Trawczyński J.
PMID: 35010039
Nanomaterials (Basel). 2021 Dec 29;12(1). doi: 10.3390/nano12010089.

We present the comparative analysis of three Zn-based sorbents for the process of sulphur removal from hot coal gas. The sorbents were prepared by a slurry impregnation of TiO

Identification of Large Isotope Anomalies in Quartz by Infrared Spectroscopy.

Applied spectroscopy

Ogliore RC, Dwyer C, Krawczynski MJ, Couvy H, Eisele M, Filiberto J.
PMID: 31107100
Appl Spectrosc. 2019 Jul;73(7):767-773. doi: 10.1177/0003702819842558. Epub 2019 May 20.

We report an infrared (IR) spectroscopic technique to detect quartz grains with large isotope anomalies. We synthesized isotopically doped quartz and used Fourier transform infrared spectroscopy (FT-IR) in two different instruments: a traditional far-field instrument and a neaSpec nanoFT-IR,...

Association of Genes Related to Oxidative Stress with the Extent of Coronary Atherosclerosis.

Life (Basel, Switzerland)

Racis M, Stanisławska-Sachadyn A, Sobiczewski W, Wirtwein M, Krzemiński M, Krawczyńska N, Limon J, Rynkiewicz A, Gruchała M.
PMID: 32961879
Life (Basel). 2020 Sep 18;10(9). doi: 10.3390/life10090210.

Oxidative stress is believed to play a critical role in atherosclerosis initiation and progression. In line with this, in a group of 1099 subjects, we determined eight single nucleotide polymorphisms (SNPs) related to oxidative stress (

Fatigue-Induced Scapular Dyskinesis in Healthy Overhead Athletes.

Frontiers in bioengineering and biotechnology

Zago M, Kawczyński A, Klich S, Pietraszewski B, Galli M, Lovecchio N.

Front Bioeng Biotechnol. 2020 Apr 21;8:302. doi: 10.3389/fbioe.2020.00302. eCollection 2020.

Alterations of scapular kinematics affect the whole kinematic chain, potentially leading to the impingement syndrome. This is crucial in overhead sports, where athletes perform frequent and quick upper limb actions. In this manuscript, we aimed to assess the extent...

Oxidative Stress-Part of the Solution or Part of the Problem in the Hypoxic Environment of a Brain Tumor.

Antioxidants (Basel, Switzerland)

Krawczynski K, Godlewski J, Bronisz A.

Antioxidants (Basel). 2020 Aug 14;9(8). doi: 10.3390/antiox9080747.

Rapid growth of brain tumors such as glioblastoma often results in oxygen deprivation and the emergence of hypoxic zones. In consequence, the enrichment of reactive oxygen species occurs, harming nonmalignant cells and leading them toward apoptotic cell death. However,...
