All animals were discharged from the hospital (median hospitalization time after stent placement, 18 hours (range, 4 hours to 7 days)) with an indwelling, double-pigtail ureteral stent (3 bilateral and 9 unilateral) in place. All stents evaluated 0.25 to 11 months after placement

were considered patent.

Conclusions and Clinical Relevance-Findings suggested that ureteral stent placement was safe, effective, and well tolerated in patients with malignant ureteral obstructions. Stents could be reliably placed in a minimally invasive manner and remain patent long-term. Ureteral stent placement should be considered as early as possible in patients with neoplasia, prior to the development of permanent renal damage. (J Am Vet Med Assoc 2011;238:1017-1025)”
“Purpose:

The data concerning the relation between subclinical hypothyroidism MK-1775 (SH) and the risk of cardiovascular disease are divergent. We aimed to assess myocardial perfusion in contrast-enhanced echocardiography and intima-media thickness (IMT) in patients with SH.

Material/Methods: Forty females with selleckchem SH without symptoms of coronary artery disease and 15 healthy female volunteers were examined. Echocardiographic evaluation of the left ventricle function as well as carotid and femoral IMT complex measurements were performed at baseline. Thereafter, dobutamine stress echocardiography with myocardial perfusion assessment at rest and on the peak of stress test was performed. SonoVue (R) intravenous bolus as a contrast medium was used. The myocardial perfusion was assessed by quantitative method using Q-LAB Philips software (ROI modality). The perfusion index was calculated (a number of left ventricle

segments with improved perfusion/a number of all segments).

Results: A mean IMT value in the SH group was significantly higher than in the controls (0.7 mm vs. 0.38 mm, p=0.001). Myocardial perfusion at rest and at the peak of stress test was significantly lower in the SH patients as compared to the controls (at rest 120 Db in SH vs. 181 Db in controls, p=0.039 and at the peak of stress 115 Db and 188 Db, p=0.01, respectively). The perfusion index was not significantly KPT-8602 worse in the SH group (p=0.6). IMT values negatively correlated with the myocardial perfusion index at the peak of stress (r=-0.54, p=0.014).

Conclusions: In patients with SH contrast-enhanced echocardiographic examination revealed myocardial hypoperfusion and increased IMT. Our results may suggest that the patients with SH are at risk of the development of cardiovascular disease.”
“In this paper we study the reflection, absorption, and transmission of microwave from nonuniform hydrogen gas in carbon nanotubes, grown by iron-catalyzed high-pressure carbon monoxide disproportionate (HiPco) process. A discussion on the effect of various hydrogen gas parameters on the reflected power, absorbed power, and transmitted power is presented.
