Arrhythmogenic right ventricular cardiomyopathy with sustained ventricular tachycardia: a case report.

Introduction: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an infrequent hereditary disorder distinguished by fibrofatty replacement of the myocardium in the right ventricular, which predisposes individuals to life-threatening arrhythmias. This case delineates an ARVC patient who suffered recurrent bouts of sustained ventricular tachycardia (VT). In this case, we mainly discuss the application of myocardial contrast echocardiography (MCE) in displaying myocardial fibrosis in patients with ARVC.

Life history responses of spring-and autumn-germinated ephemeral plants to increased nitrogen and precipitation in the Gurbantunggut Desert.

Nitrogen deposition and precipitation change are not only hot topics of current global change but also the main environmental factors affecting plant growth. Thus, the effects of nitrogen and precipitation on the life history of spring-(SG) and autumn-germinated (AG) ephemeral plants of Erodium oxyrhynchum were researched in the Gurbantunggut Desert, northern China, and the aim was to understand the response of plants from different germination seasons to global change. SG and AG plants with increased nitrogen and precipitation plus nitrogen treatments were measured to determine seedling survival, phenology, plant traits, biomass accumulation and allocation and dormancy characteristics of offspring (seeds).

Thiazole Orange derivatives: synthesis, fluorescence properties, and labeling cancer cells.

A series of Thiazole Orange (TO) derivatives were synthesized and modified by introducing different substitutional groups on benzothiazole and 4-methylquinoline All the TO derivatives were confirmed by (1)HNMR and MS. TO derivative bearing NH(2)- was modified by folic acid and used to label breast cancer cells. The phenomenon of fluorescence enhancement was shown by the fluorescence spectrums of TO derivatives and micrographs of the labeled breast cancer cells.
