J Hum Kinet. 2015 Jan 12;48:7-16. doi: 10.1515/hukin-2015-0086. eCollection 2015 Nov 22.

Medical care in disabled sports is crucial both as prophylaxis and as ongoing medical intervention. The aim of this paper was to present changes in the quality of medical care over the consecutive Paralympic Games (PG). The study encompassed...

Analysis and performance of the control systems of the NASA 70-meter antennas.

ISA transactions

Gawronski W, Ahlstrom HG, Bernardo AM.
PMID: 15535397
ISA Trans. 2004 Oct;43(4):597-610. doi: 10.1016/s0019-0578(07)60171-2.

The control systems of the NASA 70-m antennas include the antenna control system, the Master Equatorial (ME) control system, and their combinations (called modes). The Master Equatorial is a small telescope mounted on the top of a tower located...

New macrocycles with planar chirality-synthesis and determination of absolute configurations.

Chemistry (Weinheim an der Bergstrasse, Germany)

Kalisiak J, Skowronek P, Gawroński J, Jurczak J.
PMID: 16557625
Chemistry. 2006 May 24;12(16):4397-406. doi: 10.1002/chem.200501409.

A versatile system for preparing macrocyclic compounds with planar chirality is presented. In this system chiral diazacoronands are synthesized readily from lariat-type diesters 13 and 14 and unsymmetrical diamines 7, 8, 12, 15, and 16 under non-high-dilution conditions. The...

Conformational response of tartaric acid to derivatization: role of 1,3-dipole-dipole interactions.

Chirality

Gawronski J, Długokinska A, Grajewski J, Plutecka A, Rychlewska U.
PMID: 15991225
Chirality. 2005 Aug;17(7):388-95. doi: 10.1002/chir.20181.

The four-carbon chain in (R,R)-tartaric acid derivatives is predominantly antiperiplanar (trans) in the acid, its salts, esters, and NH-amides, while (-)-synclinal (gauche) conformer is the most abundant in N,N'-tetraalkyltartramides. Trialkylsilylation or tert-butylation of the hydroxy groups at C2 and...

Probing the shapes of chiral bis-(o-naphthalimidobenzoyl) systems using X-ray and circular dichroism methods.

Acta crystallographica. Section B, Structural science

Rychlewska U, Plutecka A, Hoffmann M, Skowronek P, Gawrońska K, Gawroński J.
PMID: 19155562
Acta Crystallogr B. 2009 Feb;65:86-95. doi: 10.1107/S0108768108041827. Epub 2009 Jan 15.

CD (circular dichroism) and X-ray investigations have been carried out in order to identify the prevalent conformations and define the forces that determine the molecular and supramolecular organization of the alkyl-bridged bichromophoric [NAB, ortho-(1,8-naphthalimido)benzoyl] units, each consisting of the...

Imaging phonon excitation with atomic resolution.

Science (New York, N.Y.)

Gawronski H, Mehlhorn M, Morgenstern K.
PMID: 18276884
Science. 2008 Feb 15;319(5865):930-3. doi: 10.1126/science.1152473.

Inelastic electron tunneling spectroscopy at low temperatures was used to investigate vibrations of Au(111) and Cu(111). The low-energy peaks at 9 millielectron volts (meV) on Au(111) and 21 meV on Cu(111) are attributed to phonons at surfaces. On Au(111),...

Introduction of axial chirality at a spiro carbon atom in the synthesis of pentaerythritol-imine macrocycles.

Organic & biomolecular chemistry

Grajewski J, Piotrowska K, Zgorzelak M, Janiak A, Biniek-Antosiak K, Rychlewska U, Gawronski J.
PMID: 29344591
Org Biomol Chem. 2018 Feb 07;16(6):981-987. doi: 10.1039/c7ob02672b.

Novel chiral macrocyclic polyimines with spiro carbon atoms are described. The key feature of the synthesis is the formation of an axially chiral quaternary carbon atom having four constitutionally identical substituents. This is possible either by the freezing of...

Destructive influence of interlayer coupling on Heider balance in bilayer networks.

Scientific reports

Górski PJ, Kułakowski K, Gawroński P, Hołyst JA.
PMID: 29167566
Sci Rep. 2017 Nov 22;7(1):16047. doi: 10.1038/s41598-017-15960-y.

We consider the problem of Heider balance in a link multiplex, i.e. a special multiplex where coupling exists only between corresponding links. Numerical simulations and analytical calculations demonstrate that the presence of such interlayer connections hinders the emergence of...

Solvent-assisted synthesis of a shape-persistent chiral polyaza gigantocycle characterized by a very large internal cavity and extraordinarily high amplitude of the ECD exciton couplet.

Chemical communications (Cambridge, England)

A giant, chiral square-shaped octaimine macrocycle has been obtained in a controlled manner from readily available and inexpensive substrates: 9,10-diphenylanthracene-based dialdehyde and trans-1,2-diaminocyclohexane. Reduction of the polyimine led to a chiral octaamine characterized by a very large internal hydrophobic...

Secondary Structure of Chloroplast mRNAs In Vivo and In Vitro.

PMID: 32143324
Plants (Basel). 2020 Mar 04;9(3). doi: 10.3390/plants9030323.

mRNA secondary structure can influence gene expression, e.g., by influencing translation initiation. The probing of in vivo mRNA secondary structures is therefore necessary to understand what determines the efficiency and regulation of gene expression. Here, in vivo mRNA secondary...
