The angiotensin receptors type 1 (AT1) have affinity by Losartan?, low affinity to non-peptides antagonists and similar effect as Angiotensin-convert-enzyme inhibitors. It have been reported that natural and synthetic products might reduce the genotoxic and cytotoxic effects related to stannous chloride (SnCl2). SnCl2 is used in nuclear medicine as a reducing agent to obtain technetium-99 m-radiopharmaceuticals. The aim of this work was to evaluate the cellular effects produced by a solution of Losartan? (25 mg/ml) on the survival of Escherichia coli AB1157 in the presence and absence of SnCl2, and on the osmotic fragility of erythrocytes of the blood of Wistar rats. Briefly, blood sample was withdrawn by Wistar rats with heparinized syringe and incubated with Losartan? solution. Saline (NaCL 0.9%) was used as a control. The samples were gently mixed with hypotonic solutions of NaCl. After that it was centrifuged and the supernadant isolated for optical determination of the hemoglobin present. E. coli AB1157 cultures (exponential growth phase) were collected by centrifugation, washed and resuspended in 0.9%NaCl. Samples were incubated in water bath shaker with: (a) SnCl2 (25 μg/ml), (b) Losartan? (25 mg/ml) and (c) SnCl2 (25 μg/ml) + Losartan? (25 mg/ml). Incubation with 0.9% NaCl was also carried out (control). At 60 min intervals, aliquots were withdrawn, diluted, spread onto Petri dishes with solid LB medium and incubated overnight. The colonies formed were counted and the survival fractions calculated. Statistical analysis was performed. The results showed that there was a significantly increase (P < 0.05) in the osmotic fragility of the blood cells treated with Losartan?. Moreover, Losartan? was also able to protect the E. coli cultures against the lesive action of SnCl2. Although, in erythrocyte the osmotic fragility was increased by the presence of Losartan? that could 1) alter the physical properties of this cell, or 2) had a direct or indirect effect on the

The stomatognathic system (SS) is a functional unit of the body that depends on the balance of several tissues. It consists of various structures, including the temporomandibular joint. Temporomandibular disorder (TMD) can occur due to alterations in the SS. The Fonseca Anamnestic Index (FAI) is a scale used to evaluate and to characterize the TMD Type: no DTM, mild, moderate and severe. The aim is to evaluate the prevalence of signs and symptoms related to TMD in university students of the Parque das Rosas Campus, Universidade Estácio de Sá that practice sports. This investigation was approved (CAAE number 325678413.9.0000.5284). Two hundred eighth students (110 male and 98 female, aged 19 - 35 years) accepted to be in this investigation. All the participants answered a General Questionnaire (GQ) and the FAI. The GQ had questions about the age, sex and the presence of TMD. The FAI was used. A statistical difference (p > 0.05) was not found about the presence of TMD. Among the female, an elevated number of the students with signal or symptoms related to the temporomandibular with statistic significance (p < 0.05) was observed. In the population without TMD, the prevalence of this disorder is higher between male than female. Considering the FAI, among the female students, there is a prevalence of the Mild Type. Considering the evaluation of the type of TMD among the male and female students no difference was found between male and female to the types mild and moderate, however, the prevalence of the severe Type is higher in female than in male with statistical significance. In conclusion, TMD is a relevant clinical condition with an important prevalence among the university students. Moreover, the type of the TMD could be considered due to prevalence of the Type Severe among the women.

In this paper, we are interested in answering the following research question: "Is it possible to form effective groups in virtual communities by exploiting trust information without significant overhead, similarly to real user communities?"In order to answer this question, instead of adopting the largely used approach of exploiting the opinions provided by all the users of the community(called global reputation), we propose to use a particular form of reputation, called local reputation. We also propose an algorithm for group formation able to implement the proposed procedure to form effective groups in virtual communities. Another interesting question is how to measure the effectiveness of groups in virtual communities. To this aim we introduce the index in a measure of the effectiveness of the group formation. We tested our algorithm by realizing some experimental trials on real data from the real world EPINIONS and CIAO communities, showing the significant advantages of our procedure w.r.t. another prominent approach based on traditional global reputation.

Liver transplantation for intermediate hepatocellular carcinoma: An adaptive approach

引用

World Journal of Gastroenterology 2017年第18期23卷 3195-3204页

作者： Marco Biolato giuseppe Marrone Luca Miele antonio Gasbarrini antonio Grieco Liver Transplant Medicine Gastroenterological Area Gastroenterological and Endocrino Metabolical Sciences Department Fondazione Policlinico Universitario Gemelli Universita’ Cattolica del Sacro Cuore

Hepatocellular carcinoma is becoming an increasing indication for liver transplantation, but selection and allocation of patients are challenging because of organ shortages. Conventional Milan criteria are the reference for the selection of patients worldwide, but many expanded criteria, like University of California San Francisco criteria and up-to-7 criteria, have demonstrated that survival and recurrence results are lower than those for restricted indications. Correct staging is crucial and should include surrogate markers of biological aggressiveness(α-fetoprotein, response to loco-regional treatments). Successful down-staging can select between patients with tumor burden initially beyond transplantation criteria those with a more favorable biology, provided a 3-mo stability in meeting the transplantation criteria. Allocation rules are constantly adjusted to minimize the imbalance between the priorities of candidates with and without hepatocellular carcinoma, and take into account local donor rate and waitlist dynamics. Recently, Mazzaferro et al proposed a benefit-oriented "adaptive approach", in which the selection and allocation of patients are based on their response to non-transplantation treatments: low priority for transplantation in case of complete response, high priority in case of partial response or recurrence, and no listing in case of progression beyond transplantation criteria.

Osmoprotectants and Antioxidative Enzymes as Screening Tools for Salinity Tolerance in Radish (Raphanus sativus)

引用

Horticultural Plant Journal 2020年第1期6卷 14-24页

作者： Rabab Sanoubar antonio Cellini giuseppe Gianfranco Francesco Spinelli Department of Agricultural Sciences (DIPSA) University of Bologna

The research addresses the identification of a screening methodology for salt stress tolerance in radish cultivars. In the first experiment, two different radish cultivars(long white and round red) were compared in their morphological and physiological responses to different salinity levels. Round red radish showed better morphological and physiological responses to incremental salinity in terms of yield and better adaptation of overall water relations. In the second experiment, the most tolerant genotype from the first experiment was used as a control against other seven round red radish genotypes ranked by their salinity tolerance according to morphological, physiological and biochemical indices. Salt stress did not significantly affect malondialdehyde(MDA) and hydrogen peroxide(H2O2) content, and ascorbate peroxidase(APX) activity in the studied cultivars. Nonetheless, the relatively salt tolerant cultivar SAXA2 showed higher ability to accumulate compatible solutes(*** and proteins) and maintain osmotic adjustment. In addition, cultivar SAXA2 also showed considerable increase in glutathione reductase(GR) activity. Our results supported that accumulation of proline and higher GR activity are associated with radish salt tolerance, whereas no relationship with salinity was observed in superoxide dismutase(SOD), MDA and H2O2 content.

Rectal perforation by inadvertent ingestion of a blister pack: A case report and review of literature

The accidental ingestion of a foreign body(FB) is a relatively common condition. In the present study, we report a peculiar case of rectal perforation, the first to our knowledge, caused by the inadvertent ingestion of a blister pill pack. The aim of this report is to illustrate the difficulties of the case from a diagnostic and therapeutic viewpoint as well as its unusual presentation. A 75-year-old woman, mentally impaired, arrived at our emergency department in critical condition. The computed tomography scan revealed a substantial abdominopelvic peritoneal effusion and free perigastric air. The patient was therefore submitted to an urgent exploratory laparotomy; a 2-cm long, full-thickness lesion was identified in the anterior distal part of the intraperitoneal rectum. Hence, we performed a Hartmann's procedure. Because of her critical condition, the patient was eventually transferred to the Intensive Care Unit, where she died after 10 d, showing no surgical complication. The ingestion of FBs is usually treated with observation or endoscopic removal. Less than 1% of FBs are likely to cause an intestinal perforation. The intestinal perforation resulting from the unintentional ingestion of an FB is often a difficult challenge when it comes to treatment, due to its late diagnosis and the patients' deteriorated clinical condition.
