How to detect silent myocardial ischemia.

Postgraduate medicine

Weiner DA.
PMID: 2813228
Postgrad Med. 1989 Nov 15;86(7):81-4, 95-7. doi: 10.1080/00325481.1989.11700775.

Anginal pain alone is not a sensitive marker of ischemia. In one study of 2,014 completely asymptomatic men, 2.5% were found to have silent ischemia when they underwent treadmill exercise testing. Another method of detection, ambulatory electrocardiographic monitoring, can...

[Painless obstruction of the left coronary trunk. Apropos of a case].

Annales de cardiologie et d'angeiologie

Selton-Suty C, Danchin N, Juillière Y, Karcher G, Villemot JP, Cherrier F.
PMID: 2188561
Ann Cardiol Angeiol (Paris). 1990 Mar;39(3):161-3.

The originality of this observation of the complete occlusion of the left coronary artery lies in its painless character on the angina level. The affection was revealed by the clinical manifestations of the left ventricular failure in severe ischaemic...

J Am Chem Soc. 2014 Aug 27;136(34):12056-63. doi: 10.1021/ja505826x. Epub 2014 Aug 19.

Reported are the rational synthesis, structures, and solution dynamics of three tetrasubstituted and neutral Ge9-based deltahedral clusters [Ge9R3R'](0), where R = Si(SiMe3)3 and R' = Et (1), Sn(n)Bu3 (2), or Tl (3). The first step of the synthesis is...

Is It Angina?.

Cantwell JD.
PMID: 27424641
Phys Sportsmed. 1992 Apr;20(4):74-82. doi: 10.1080/00913847.1992.11710274.

In brief Most chest pain in athletes is brief noncardiac, and it resolves spontaneously or with appropriately directed treatment. But when the patient's medical history suggests angina pectoris, accurate diagnosis of cardiac disease is imperative. If cardiac examination suggests...

LiNbO3-Type Oxide (Tl(1-x)Sc(x))ScO3: High-Pressure Synthesis, Crystal Structure, and Electronic Properties.

Inorganic chemistry

Belik AA, Yi W, Kumagai Y, Katsuya Y, Tanaka M, Oba F.
PMID: 26840839
Inorg Chem. 2016 Feb 15;55(4):1940-5. doi: 10.1021/acs.inorgchem.5b02915. Epub 2016 Feb 03.

We investigate the synthesis of a thallium scandate, TlScO3, under high-pressure (6-7.7 GPa) and high-temperature (1373-1773 K) conditions. At 6 GPa, a LiNbO3-type phase appears in a narrow temperature range and in mixtures with other phases. At 7.7 GPa...

Thallium Transfer from Hydrochloric Acid Media into Pure Ionic Liquids.

The journal of physical chemistry. B

Tereshatov EE, Boltoeva MY, Mazan V, Volia MF, Folden CM.
PMID: 26769597
J Phys Chem B. 2016 Mar 10;120(9):2311-22. doi: 10.1021/acs.jpcb.5b08924. Epub 2016 Feb 25.

Pure hydrophobic ionic liquids are known to extract metallic species from aqueous solutions. In this work we have systematically investigated thallium (Tl) extraction from aqueous hydrochloric acid (HCl) solutions into six pure fluorinated ionic liquids, namely imidazolium- and pyrrolidinium-based...

Simultaneous removal of thallium and chloride from a highly saline industrial wastewater using modified anion exchange resins.

Journal of hazardous materials

Li H, Chen Y, Long J, Jiang D, Liu J, Li S, Qi J, Zhang P, Wang J, Gong J, Wu Q, Chen D.
PMID: 28355586
J Hazard Mater. 2017 Jul 05;333:179-185. doi: 10.1016/j.jhazmat.2017.03.020. Epub 2017 Mar 11.

Simultaneous removal of thallium (Tl) and chloride from a highly saline industrial wastewater was investigated using modified anion ion exchange resins. The removal of thallium was mainly driven by the exchange of Tl-chlorocomplex (TlCl

4,5-Dihydro-1,2,3-oxadiazole: A Very Elusive Key Intermediate in Various Important Chemical Transformations.

Chemistry (Weinheim an der Bergstrasse, Germany)

Banert K, Singh N, Fiedler B, Friedrich J, Korb M, Lang H.
PMID: 26260871
Chemistry. 2015 Oct 19;21(43):15092-9. doi: 10.1002/chem.201502326. Epub 2015 Aug 10.

4,5-Dihydro-1,2,3-oxadiazoles are postulated to be key intermediates in the industrial synthesis of ketones from alkenes, in the alkylation of DNA in vivo, and in the decomposition of N-nitrosoureas; they are also a subject of great interest for theoretical chemists....
