PMID: 24697452
J Chem Phys. 2014 Mar 28;140(12):124318. doi: 10.1063/1.4869595.

Molecular beam scattering experiments have been performed to study the effect of long-range anisotropic forces on the collision dynamics of two small polar molecules. The main focus of this paper is on water, but also ammonia and hydrogen sulphide...

Influence of heat treatment on structural, mechanical and wear properties of crosslinked UHMWPE.

Journal of applied biomaterials & biomechanics : JABB

Chiesa R, Moscatelli M, Giordano C, Siccardi F, Cigada A.
PMID: 20803447
J Appl Biomater Biomech. 2004 Jan-Apr;2(1):20-8.

New crosslinked ultra high molecular weight polyethylenes (UHMWPEs) have recently been developed, characterized and introduced in clinical applications. UHMWPE cross-linking treatments are very promising for reducing osteolysis induced by wear debris. The irradiation type, gamma or beta, the dosage...

Photodegradation and photostabilization of polymers, especially polystyrene: review.

SpringerPlus

Yousif E, Haddad R.
PMID: 25674392
Springerplus. 2013 Aug 23;2:398. doi: 10.1186/2193-1801-2-398. eCollection 2013.

Exposure to ultraviolet (UV) radiation may cause the significant degradation of many materials. UV radiation causes photooxidative degradation which results in breaking of the polymer chains, produces free radical and reduces the molecular weight, causing deterioration of mechanical properties...

High performance liquid chromatography (HPLC) fingerprints and primary structure identification of corn peptides by HPLC-diode array detection and HPLC-electrospray ionization tandem mass spectrometry.

Journal of food and drug analysis

Wang C, He H, Zhang JL, Li X, Ma ZL.
PMID: 28911415
J Food Drug Anal. 2016 Jan;24(1):95-104. doi: 10.1016/j.jfda.2015.05.005. Epub 2015 Jul 22.

Corn peptides (CPs) are reported to have many biological functions, such as facilitating alcohol metabolism, antioxidation, antitumor, antihypertension, and hepatoprotection. To develop a method for quality control, the high-performance liquid chromatography (HPLC) system was applied. Twenty-eight common peaks were...

ESR Spin Trapping Studies of Free Radicals Generated from Nitrofuran Derivative Analogues of Nifurtimox by Electrochemical and Trypanosoma cruzi Reduction.

Free radical research

Olea-Azar C, Rigol C, Mendizabal F, Morello A, Diego Maya J, Moncada C, Cabrera E, di Maio R, González M, Cerecetto H.
PMID: 28447529
Free Radic Res. 2003;37(9):993-1001. doi: 10.1080/10715760310001598141.

Electron spin resonance (ESR) spectra of radicals obtained from two analogues of the antiprotozoal drug nifurtimox by electrolytic and Trypanosoma cruzi reduction were analyzed. The electrochemistry of these compounds was studied using cyclic voltammetry. STO 3-21G ab initio and...

Toxicological Evaluation of Emblica officinalis Fruit Extract and its Anti-inflammatory and Free Radical Scavenging Properties.

BACKGROUND: Emblica officinalis (Euphorbiaceae), popularly known as Indian gooseberry or "Amla" in India, is used in Ayurveda as "rejuvenating herb" since ancient times.OBJECTIVE: This study was carried out to estimate toxicity, anti-inflammatory, and antioxidative activities of the methanolic extract...

Halothane suppresses the increase in intracellular calcium concentration of isolated rat myocytes during hydrogen peroxide perfusion.

Journal of anesthesia

Nonaka A, Kashimoto S, Iwashita H, Kumazawa T.
PMID: 28921228
J Anesth. 1995 Sep;9(3):260-264. doi: 10.1007/BF02479875.

Ischemia-reperfusion injury is probably caused by the generation of oxygen free radicals. The final common pathway to cell injury may be mediated by intracellular calcium overloading induced by oxygen free radicals. Volatile anesthetics have been shown to improve myocardial...
