Touil A, Peczalski R, Timoumi S, Zagrouba F.
PMID: 26556000
J Pharm (Cairo). 2013;2013:892632. doi: 10.1155/2013/892632. Epub 2012 Dec 05.

The effect of hygrothermal conditions (air temperature and relative humidity) on the dehydration of theophylline monohydrate was investigated. Firstly, the equilibrium states of theophylline were investigated. The data from gravimetric analysis at constant temperature and humidity were reported as...

Sci Rep. 2021 Nov 01;11(1):21345. doi: 10.1038/s41598-021-00880-9.

The active DNA demethylation process may be linked to aberrant methylation and may be involved in leukemogenesis. We investigated the role of epigenetic DNA modifications in childhood acute lymphoblastic leukemia (ALL) diagnostics and therapy monitoring. We analyzed the levels...

The Effect of Liquid Slurry-Enhanced Corrosion on the Phase Composition of Selected Portland Cement Pastes.

Materials (Basel, Switzerland)

Durczak K, Pyzalski M, Pilarski K, Brylewski T, Sujak A.
PMID: 33808447
Materials (Basel). 2021 Mar 30;14(7). doi: 10.3390/ma14071707.

This paper presents the scientific problem of the biological corrosion of Portland cements and its effects on the phase composition of cement pastes after the corrosion process in the environment of reactive media from the agricultural industry. Seven Portland...

Urinary Measurement of Epigenetic DNA Modifications: A Non-Invasive Assessment of the Whole-Body Epigenetic Status in Healthy Subjects and Colorectal Cancer Patients.

ChemistryOpen

Rozalski R, Gackowski D, Siomek-Gorecka A, Banaszkiewicz Z, Olinski R.
PMID: 28032024
ChemistryOpen. 2016 Nov 15;5(6):550-553. doi: 10.1002/open.201600103. eCollection 2016 Dec.

Active mechanism of DNA demethylation can be responsible for the activation of previously silenced genes. Products of 5-methylcytosine oxidation are released into the bloodstream and eventually excreted with urine. Therefore, whole-body epigenetic status can be assessed non-invasively on the...

Structure of chicken skeletal muscle troponin C at 1.78 A resolution.

Acta crystallographica. Section D, Biological crystallography

Satyshur KA, Pyzalska D, Greaser M, Rao ST, Sundaralingam M.
PMID: 15299475
Acta Crystallogr D Biol Crystallogr. 1994 Jan 01;50:40-9. doi: 10.1107/S090744499300798X.

The structure of chicken skeletal muscle troponin C (TnC) has been refined to an R value of 0.168, using 14 788 reflections, in the resolution range 8.0-1.78 A. Our earlier 2 A resolution structure [Satyshur, Rao, Pyzalska, Drendel, Greaser...

The acoustic field and the location of cavitation bubble are computed in vials used for freeze-drying, insonified from the bottom by a vibrating plate. The calculations rely on a nonlinear model of sound propagation in a cavitating liquid [Louisnard,...
