AIM: This prospective study evaluated the effectiveness of 90 W argon plasma coagulation (APC) for the ablation of Barrett's esophagus (BE) that is considered to be the main risk factor for the development of esophageal ***: The results from 25 patients, observed at the First Department of General Surgery, University of Verona, Italy, from October 2000 to October 2003, who underwent APC for histologically proven BE were prospectively ***: The ablation treatment was completed in all the patients but one (96%). The mean number of APC sessions needed to complete ablation was 1.6 (total number: 40). The eradication was obtained in the majority of cases by one session only (60%), two sessions were required in 24% of the cases and three or more in 16%.About 43% of the sessions were complicated. Retrosternal pain (22.5%) and fever (17.5%) were the most frequent symptoms. Only one major complication occurred, it was an hemorrhage due to ulcer formation on the treated esophagus that required urgent endoscopic sclerosis and admission. The follow-up was accomplished in all the patients with a mean period of 26.3 mo and 20 patients (84%) with a follow-up period longer than 24 mo. Only one patient showed a relapse of metaplastic mucosa 12 mo after the completion of ablation. The patient was hence re-treated and now is free from recurrence 33 mo ***: High power setting (90 W) APC showed to be safe and effective. The effects persist at a mean follow-up period of two years with a comparable cost in term of complications with respect to standard power settings. Further studies with greater number of patients are required to confirm these results and to assess if ablation reduces the incidence of malignant progression.

The present paper aims at showing how it is possible to requalify the structures of an urban system, in order to increase its resistance and its correlative resilience, against natural calamities (earthquakes, hurricanes, etc.), by adopting as reference criterion the Maximum Ordinality Principle (MOP). In this sense, the paper opens a radically new perspective in this field. In fact, the village assumed as a case study was modelled as a Self-Organizing System. This is because, although the village is usually considered as being solely made of buildings, streets, places and so on, in reality it has been conceived, planned and realized by human beings during several centuries. In addition, the people who actually leave in such an urban center, systematically deal with its maintenance, in order to possibly increase its functionality. This justifies the assumption of the village as being a Self-Organizing System and, consequently, it has been analyzed in the light of the MOP, which represents a valid reference principle for analyzing both “non-living”, “living” and “conscious” self-organizing systems.

AIM To evaluate the clinical significance of the preoperative fibrinogen plasma level as a prognostic marker after surgery for colorectal *** This retrospective study analysed 652 patients undergoing surgery for stage Ⅰ-Ⅳ colorectal cancer between January 2005 and December 2012, at the Division of General Surgery A, University of Verona Hospital Trust, in whom preoperative fibrinogen plasma values were assessed at baseline. Fibrinogen is involved in tumourigenesis as well as tumour progression in several malignancies. Correlations between preoperative plasma fibrinogen values and clinicopathological characteristics were investigated. Univariate and multivariate survival analyses were performed to identify factors associated with overall and tumour-related *** Among the 652 patients, the fibrinogen value was higher than the threshold of 400 mg/dL in 345 patients(53%). The preoperative mean ± SD of fibrinogen was 426.2 ± 23.2 mg/dL(median: 409 mg/dL; range: 143-1045 mg/d L). Preoperative fibrinogen values correlated with age(P = 0.003), completeness of tumour resection, potentially curative vs palliative(P < 0.001), presence of systemic metastasis(P < 0.001), depth of tumour invasion p T(P < 0.001), nodes involvement p N(P = 0.001) and CEA serum level(P < 0.001). The mean fibrinogen value(± SD) was 395.6 ± 120.4 mg/d L in G1 tumours, 424.1 ± 121.4 mg/dL in G2 tumours and 453.4 ± 131.6 mg/dL in G3 tumours(P = 0.045). The overall survival and tumourrelated survival were significantly higher in patients with fibrinogen values ≤ 400 mg/d L(P < 0.001). However, hyperfibrinogenemia did not retain statistical significance regarding either overall(P = 0.313) or tumour-related survival(P = 0.355) after controlling for other risk factors in a multivariate *** Preoperative fibrinogen levels correlate with cancer severity but do not help in predicting patient prognosis after colorectal cancer surgery.

We describe an uncommon case of a patient with a metastatic adenocarcinoma of ovarian origin presented as a gastric subepithelial tumor(SET) and that was diagnosed by endoscopic ultrasound fine-needle biopsy(EUS-FNB). Malignant gastric lesions are rarely metastatic and the primary tumor is mainly breast, lung, esophageal cancer or cutaneous melanoma. Gastric metastasis from ovarian cancer is unusual, presenting synchronously with the primary tumor but also several years later than the initial diagnosis. From an endoscopic point of view, gastric metastasis does not present specific features. They may mimic both a primary gastric tumor or, less frequently, an *** case demonstrates the importance of EUS-FNB in distinguishing SETs and how this may alter treatment and prognosis.

AIM： To evaluate the levels of serum carnitine in patients with cancer in digestive organs and to compare them with other cancers in order to provide new insights into the mechanisms of cachexia. METHODS： Fifthy-five cachectic patients with or without gastrointestinal cancer were enrolled in the present study. They underwent routine laboratory investigations, including examination of the levels of various forms of carnitine present in serum （i.e., long-chain acylcarnitine, short-chain acylcarnitine, free carnitine, and total carnitine）. These values were compared with those found in 60 cancer patients in good nutritional status as well as with those of 30 healthy control subjects. RESULTS： When the cachectic patients with gastrointestinal cancer were compared with the cachectic patients without gastrointestinal cancer, the difference was -6.8 μmol/L in free carnitine （P 〈 0.005）, 0.04 μmol/ L in long chain acylcarnitine （P 〈 0.05）, 8.7 μmol/L in total carnitine （P 〈 0.001）. In the cachectic patients with or without gastrointestinal cancer, the difference was 12.2 μmol/L in free carnitine （P 〈 0.001）, 4.60 μmol/L in short chain acylcarnitine （P 〈 0.001）, and 0.60 μmol/L in long-chain acylcarnitine （P 〈 0.005） and 17.4 μmol/L in total carnitine （P 〈 0.001）. In the cachectic patients with gastrointestinal cancer and the healthy control subjects, the difference was 15.5 μmol/L in free carnitine （P 〈 0.001）, 5.2 μmol /L in short-chain acylcarnitine （P 〈 0.001）, 1.0 μmol/L in long chain acylcarnitine （P 〈 0.001）, and 21.8 μmol/L in total carnitine （P 〈 0.001）. CONCLUSION： Low serum levels of carnitine in terminal neoplastic patients are decreased greatly due to the decreased dietary intake and impaired endogenous synthesis of this substance. These low serum carnitine levels also contribute to the progression of cachexia in cancer patients.

Brassinosteroid （BR） hormone signaling controls multiple processes during plant growth and development and is initiated at the plasma membrane through the receptor kinase BRASSINOSTEROID INSENSITIVE1 （BRI1） together with co-receptors such as BRI1-ASSOClATED RECEPTOR KINASE1 （BAK1）. BRI1 abun- dance is regulated by endosomal recycling and vacuolar targeting, but the role of vacuole-related proteins in BR receptor dynamics and BR responses remains elusive. Here, we show that the absence of two DUF300 domain-containing tonoplast proteins, LAZARUS1 （LAZl） and LAZl HOMOLOG1 （LAZlH1）, causes vacuole morphology defects, growth inhibition, and constitutive activation of BR signaling. Intriguingly, tonoplast accumulation of BAK1 was substantially increased and appeared causally linked to enhanced BRI1 trafficking and degradation in lazl lazlhl plants. Since unrelated vacuole mutants exhibited normal BR responses, our findings indicate that DUF300 proteins play distinct roles in the regulation of BR signaling by maintaining vacuole integrity required to balance subcellular BAK1 pools and BR receptor distribution.
