[Q]: Accurate evaluation of the biological behavior of Gastrointestinal stromal tumor and careful selection of patients with a high risk for tumor recurrence are necessary. In the present study, we analyzed prognostic factors in patients with GIST.', 'A total of 214 patients who had undergone curative resection of a localized primary gastric GIST without adjuvant therapy were enrolled in this retrospective study. Prognostic factors were analyzed. The growth pattern was classified as intramural, endoluminal, exoluminal, or mixed- type.', 'On univariate and multivariate analyses, recurrence was predicted by exoluminal or mixed-type (hazard ratio [HR]=3.7, p=0.043), tumor size of >3.5 cm (HR=7.1, p=0.01), and mitotic rate of >5/50 high-power fields (HR=7.9, p<0.001).

[Q]: The development of techniques that allow the imaging of animals infected with parasites expressing luciferase opens up new possibilities for following the fate of parasites in infected mammals.', 'D-luciferin potassium salt stock solution was prepared in phosphate-buffered saline (PBS) at 15 mg/ml. To produce bioluminescence, infected and control mice received an intraperitoneal injection of luciferin stock solution (150 mg/kg). All mice were immediately anesthetized with 2% isofluorane, and after 10 minutes were imaged. Ex vivo evaluation of infected tissues and organs was evaluated in a 24-well plate in 150 μg/ml D-luciferin diluted in PBS. Images were captured using the IVIS Lumina image system (Xenogen). Dissected organs were also evaluated by microscopy of hematoxylin-eosin stained sections.', 'Here we describe the results obtained using a genetically modified Dm28c strain of T. cruzi expressing the firefly luciferase to keep track of infection by bioluminescence imaging. Progression of infection was observed in vivo in BALB/c mice at various intervals after infection with transgenic Dm28c-luc. The bioluminescent signal was immediately observed at the site of T. cruzi inoculation, and one day post infection (dpi) it was disseminated in the peritoneal cavity. A similar pattern in the cavity was observed on 7 dpi, but the bioluminescence was more intense in the terminal region of the large intestine, rectum, and gonads. On 14 and 21 dpi, bioluminescent parasites were also observed in the heart, snout, paws, hind limbs, and forelimbs. From 28 dpi to 180 dpi in chronically infected mice, bioluminescence declined in regions of the body but was concentrated in the gonad region. Ex vivo evaluation of dissected organs and tissues by bioluminescent imaging confirmed the in vivo bioluminescent foci. Histopathological analysis of dissected organs demonstrated parasite nests at the rectum and snout, in muscle fibers of mice infected with Dm28c-WT and with Dm28c-luc, corroborating the bioluminescent imaging.

[Q]: Adiponectin, an adipose tissue derived hormone, is known to have insulin-sensitizing, anti-inflammatory, and anti-atherogenic properties in the general population. Adiponectin secretion is suppressed by systemic inflammation, a highly prevalent condition in maintenance hemodialysis (MHD) patients. We evaluated whether short-term administration of interleukin 1 receptor antagonist (IL-1ra) improves adiponectin levels and insulin sensitivity in MHD patients.', 'Ad hoc analysis was performed on a pilot randomized placebo-controlled trial of the administration of IL-1ra in chronically inflamed MHD patients. Twenty-two patients were randomly assigned to receive 100 mg of IL-1ra or placebo (1:1) for 4 weeks, and 14 completed the trial. ANCOVA was used to compare percent change from baseline to 4 weeks. The primary outcome was percent change in adiponectin and the secondary outcomes were changes in leptin, homeostatic model assessment of insulin resistance (HOMA-IR) and the leptin-to-adiponectin ratio (LAR).', "Patients' mean age was 49 ± 13 years, and 71 % were males. At baseline, the median values for adiponectin, leptin, LAR and HOMA-IR were 11.5 μg/ml [interquartile range (IQR) 9, 28.5], 17.8 ng/ml (3.9, 50.0), 2.20 (0.13, 3.98), and 2.8 (2.0, 3.6), respectively. IL-1ra administration resulted in a mean percent increase in serum adiponectin of 22 % vs. 14 % decrease in the placebo arm (p = 0.003). Leptin, LAR or HOMA-IR levels did not change in either arm.
