Byusing a polyclonal antibody raised against smooth muscle MyosinLight Chain Kinase of adult chicken we show that the 135 kDasmooth muscle Myosin Light Chain Kinase isoform is present inneonatal and regenerating rat skeletal muscle, as well as inadult atrial myocardium. No reaction was evident in adultskeletal muscle fibres. In neonatal and in early regeneratingmuscle smooth muscle Myosin Light Chain Kinase is associated withembryonic myosin as revealed by their co-presence in musclefibres. Experiments in vitro show the same results in myotubes.In atrial myocardium there is a patchy positivity in certaingroup of myocytes. Immunoblotting experiments show in muscle cellcultures, in neonatal and in regenerating skeletal muscle aprotein band with electrophoretic mobility corresponding to thatof smooth muscle Myosin Light Chain Kinase. These results suggestthat the expression of smooth muscle Myosin Light Chain Kinase isnot fully tissue-specific and that regulation of the contractilemachinery could be different during myogenesis and in adulthood,in relation to the peculiar dynamic characteristics of developingmuscles 相似文献

Summary. Between 1970 and 1976, 290 patients with endometrial cancer were treated at the 1st Obstetrics and Gynecology Clinic of the University of Milan. The median age was 62 years. Surgery was completed in 262 (90.3%) patients. Abdominal hysterectomy was used in 158 (70.9%) stage I and 40 (71.4%) stage II/III patients; vaginal hysterectomy in 55 (24.7%) stage I and nine (16.1%) stage II/III patients. Resection of the upper vagina was performed in 168 patients. Postoperative external beam radiotherapy was used in stage II/III patients and in 44 (19.7%) stage I high-risk patients. Ten-year survival, determined by the life-table method, was 84.8% in stage I (223 patients), 53.4% in stage II (37 patients), 64.4% in stage III (19 patients), and 9.1% in stage IV (11 patients). Factors associated with poorer prognosis were: late age at diagnosis (P<0.001); deep myometrial invasion (P<0.001); poorly differentiated histological grade ( P =0.11); lack of resection of the upper vagina ( P = 0.13). The role and importance of surgery is discussed, with special emphasis on the selective use of the vaginal route in aged, obese and medically high-risk patients. 相似文献

To study the additive benefits of routine stent implantation in patients undergoing primary percutaneous transluminal coronary angioplasty (PTCA) at experienced centers, we compared the outcomes of the 982 patients undergoing PTCA for acute myocardial infarction (AMI) in the Primary Angioplasty in Myocardial Infarction-2 (PAMI-2) trial (only 1% of whom were stented) to the 312 patients in the PAMI Stent Pilot Trial (236 [76%] of whom were stented). The inclusion and exclusion criteria, PTCA methodology, and definitions used were prespecified to be identical between the two trials. Compared to the primary PTCA approach in PAMI-2, the strategy of stenting all eligible lesions in the PAMI Stent Pilot Trial was associated with reduced rates of in-hospital death (0.6% vs 2.7%, P = 0.03), reinfarction (1.3% vs 4.6%, P = 0.008), recurrent ischemia (3.5% vs 11.6%, P < 0.0001), target vessel revascularization (7.3% vs 11.4%, P = 0.04), and a shorter hospital stay (6.4 ± 4.4 vs 7.1 ± 6.2 days, P = 0.01). By multiple logistic regression analysis in 1,294 patients, stent implantation versus PTCA only was the strongest predictor of freedom from the composite in-hospital end point of death, reinfarction, or target vessel revascularization (TVR) (8.3% vs 15.0%, multivariate odds ratio = 0.4, P < 0.0001). These data strongly suggest that despite the excellent results achieved when primary PTCA is performed by experienced operators, the short-term outcomes of mechanical reperfusion can be further improved by a primary stent strategy. 相似文献

The flecainide infusion test has been proposed to screen candidates for hybrid pharmacological and ablation therapy. We report the long-term follow-up of 154 consecutive patients with paroxysmal or persistent atrial fibrillation (AF) who developed atrial flutter (AFL) during flecainide infusion (IC AFL), treated with inferior vena cava-tricuspid annulus isthmus catheter ablation and oral flecainide (hybrid therapy). Over a mean of 54.1 ± 13.1 months 82 patients (53%) remained free of AF and AFL. Flecainide was discontinued because of adverse effects in 6 patients (4%). A history of persistent AF, and the documentation of ≥1 spontaneous AFL episode before the flecainide test were independent predictors of successful hybrid therapy. In patients with paroxysmal AF without documented spontaneous AFL, the long-term efficacy of hybrid therapy was 38.5% (P = 0.03). The flecainide infusion test reliably detects candidates for hybrid therapy. The efficacy of this therapy is maintained over the long-term with a high patient compliance. 相似文献
