Adsorptive desulfurization and also denitrogenation making use of metalorganic frameworks
92 [0.41] versus 1.71 [0.31]; P less then 0.001) but not NaF (1.85 [0.28] versus 1.79 [0.60]; P=0.10). NaF uptake was concentrated at carotid bifurcations, while FDG was distributed evenly throughout arteries. Correlations between FDG and NaF TBRmax differed between bifurcations with low macrocalcification (rs=0.38; P less then 0.001) versus high macrocalcification (rs=0.59; P less then 0.001). CONCLUSIONS This is the first study to demonstrate increased uptake of both FDG and NaF in culprit carotid plaques, with discrete distributions of pathophysiology influencing vulnerability in vivo. These findings have implications for our understanding of the natural history of the disease and for the clinical assessment and management of carotid atherosclerosis.BACKGROUND The monocyte chemoattractant protein-1/CCR2 (chemokine receptor 2) axis plays an important role in abdominal aortic aneurysm (AAA) pathogenesis, with effects on disease progression and anatomic stability. We assessed the expression of CCR2 in a rodent model and human tissues, using a targeted positron emission tomography radiotracer (64Cu-DOTA-ECL1i). METHODS AAAs were generated in Sprague-Dawley rats by exposing the infrarenal, intraluminal aorta to PPE (porcine pancreatic elastase) under pressure to induce aneurysmal degeneration. Heat-inactivated PPE was used to generate a sham operative control. Rat AAA rupture was stimulated by the administration of β-aminopropionitrile, a lysyl oxidase inhibitor. Biodistribution was performed in wild-type rats at 1 hour post tail vein injection of 64Cu-DOTA-ECL1i. Dynamic positron emission tomography/computed tomography imaging was performed in rats to determine the in vivo distribution of radiotracer. RESULTS Biodistribution showed fast renal clearance. The n emission tomography is a promising new biomarker for the noninvasive assessment of AAA inflammation that may aid in associated rupture prediction.BACKGROUND To examine the impact of the Mayo adhesive probability (MAP) score on the surgical complexity of exposing the tumor during laparoscopic partial nephrectomy (LPN). PATIENTS AND METHODS Our study included 318 patients who underwent LPN from January 2017 to December 2018 at our institution. Patients were divided into a lower MAP score group (≤2, n=172) and a higher MAP score group (≥3, n=146). Perioperative outcomes were compared between the groups. The operative time was predominantly occupied by the dissection time and the warm ischemia time (WIT). RESULTS A higher MAP score was associated with a longer operative time (131 vs 110 min, p less then 0.001) and longer dissection time (71 vs 54 min, p less then 0.001), respectively. The estimated blood loss (EBL) increased in patients with a higher MAP score (50 vs 20 mL, p less then 0.001). No significant difference was found with respect to the WIT (21 vs 20 min, p=0.370). In the multivariate linear regression model, male gender (β=11.199, p=0.001), BMI (β=1.197, p=0.008) and MAP score (β=9.958, p=0.002) were significantly associated with the prolongation of dissection time. CONCLUSIONS The MAP score was significantly associated with the prolongation of dissection time during LPN. In addition, the EBL increased in patients with a higher MAP score. Therefore, the MAP score can predict surgical complexity of exposing the tumor in patients undergoing LPN.OBJECTIVE In recent years, there has been increasing interest in the use of ultrasound guidance for endoscopic and percutaneous procedures. Kidney mockups could be used for training, however, available mockups are normally incompatible with ultrasound imaging. We developed a reproducible method to manufacture an ultrasound-compatible collecting system mockup that can be made at urology laboratories. METHODS Positive and negative molding methods were used. A 3D digital model of a urinary collecting system and the overlying skin surface were segmented from computed tomography. A containment mold (negative) was made following the shape of the skin surface using 3D printing. Roscovitine inhibitor A collecting system mold (positive) was also 3D printed, but made of a dissolvable material. The containment mold was filled with a gelatin formula with the collecting system mold submersed in-situ within. After the gelatin solidified, a solution was used to dissolve the collecting system mold, but not the gelatin, leaving a cavity with the shape of the collecting system. The gelatin was extracted from the container mockup and the collecting system cavity was filled with water. The mockup was imaged with ultrasound to assess echogenicity and suitability for simulating ultrasound-guided procedures. RESULTS A clear shape corresponding to the collecting system was observed inside the gel structure. Structural integrity was maintained with no observable manufacturing marks or separation seams. Ultrasound images of the mockup demonstrated clear differentiation at the gelatin-water interface. A mock stone was placed in the collecting system and needle-targeted to simulate percutaneous needle access. CONCLUSION We developed a simple method to manufacture a personalized mockup of the renal collecting system of a patient that can be used for ultrasound-guided percutaneous needle access. Generic collecting system mockups can be used for training, and patient-specific models can be used to simulate and decide the best access path before a clinical case.OBJECTIVE To assess the diagnostic value of transrectal shear wave elastography (SWE) for detecting prostate cancer (PCa) in peripheral zone and compare it with magnetic resonance imaging (MRI). MATERIAL AND METHODS 221 patients suspected of PCa were enrolled, in which 172 patients of them underwent both SWE and MRI. Elastic value was measured in the area prepared for systematic biopsy and suspicious lesion detected on B-mode or SWE, histopathologic result was compared for each biopsy. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were derived by obtaining optimal threshold from Receiver operating characteristic (ROC) curve. The correlation between the stiffness of PCa and Gleason scores, Prognostic grades, Percentage of cancer in biopsy were evaluated by Spearman rank correlation. Multivariate logistic regression analysis was performed to determine predictors for diagnosing PCa. The diagnostic capacity of MRI and SWE for detecting PCa and clinically significant PCa in peripheral zone were assessed by comparing area under curve (AUC) of ROC curve.
