Fharmacognostic specifications, consistent with the literature, were obtained by physical and physico-chemical analyses. In addition, the detection of rutin and chlorogenic acid by Thin-Layer Chromatography (TLC) as chemical markers, were used to establish the identity of the plant material. The validation of the quantification method by High Performance Liquid
Chromatography (HPLC) made possible to establish the nitin concentration in tincture (463 mu g/mL) and to ensure their quality. These results provided the standardization of C. officinalis tincture.”
“[6 pi+2 pi]-Cycloaddition of alpha,omega-diallenes and alpha,omega-bis(trimethylsilyl)diacetylenes to 1,3,5-cycloheptatriene FG-4592 order in the presence of a two-component catalytic
system TiCl4-Et2AlCl was performed BEZ235 that led to the formation of bis(endo-bicyclo[4.2.1]nona-2,4-dienes) and bis(8-trimethylsilyl-endo-bicyclo[4.2.1]nona-2,4,7-trienes) linked by polymethylene spacer in 69-86% yields.”
“Infective endocarditis (IE) is a serious and life-threatening disease. Transplant recipients are at increased risk of acquiring serious infections. The most common organisms causing IE in solid organ transplant recipients are reported to be gram positive. IE due to Gram-negative organism has rarely been reported. We report 2 cases of renal transplant recipients who met the Duke’s criteria for IE due to Pseudomonas aeruginosa.”
“A 71-year-old man underwent intracoronary stent implantation for acute inferior myocardial infarction (MI). Immediately after diagnostic intravascular ultrasound (IVUS) at 8 months’ follow-up, an acute occlusion of the sinus node (SN) artery appeared, which developed sinus arrest with junctional escape rhythm. The serum level of high-sensitivity troponin T (TpT)
was markedly elevated on the day after the procedure (2.1-32.5 ng/l), selleck kinase inhibitor which was indicative of MI related to IVUS. Under continuous intravenous infusion of unfractionated heparin, the escape rhythm changed to lower atrial rhythm on the 4th day, and recovered to sinus rhythm on the 14th day. Coronary angiography (CAG) on 15th day showed a recanalization of the SN artery, but optical coherence tomography identified that disrupted plaque and white thrombus still existed in the ostium of the SN artery. The patient was discharged on maintenance anticoagulation therapy. We hypothesized from this case that IVUS-related myocardial injury may exist without clinical problems. Our retrospective investigation showed that the median levels of high-sensitivity TpT in 20 patients who underwent CAG and subsequent diagnostic IVUS significantly increased from 0.6 (interquartile range 0.3-1.1) to 1.6 (0.7-3.6) ng/l (P < 0.05), suggesting that IVUS may induce very low levels of myocardial injury. In conclusion, we experienced a rare case of IVUS-related MI caused by an acute occlusion of the SN artery. This case reaffirms that we should pay more attention to manipulation of IVUS catheters.
