传统农学体系源于近代实验科学浪潮,并在工业革命巨大成就的推动下不断细分,失去对农业生态系统的整体把握。导致人类重新面临粮食安全(农业生态系统破坏引发的生产力衰退)和食品安全(农业环境破坏导致食物污染物残留)的双重危机。在我国,传统农学不论作为学科还是专业都属于生态系统以下的生物组织层次,是现代化石农业带来的生产和环境问题的根源。因此,农学学科及其专业教育体系的再构极为紧迫。作者提出以农业生态学为核心理论科目,以农业生态系统管理为核心应用科目而重构传统农学学科和教育体系。本文重点探讨了农业生态系统管理的基本框架和技术选择,并深入讨论了农业生态系统管理科目的内涵、外延及其发展前景。

AIM To analyze immediate postoperative outcomes after pancreaticoduodenectomy regarding metabolic *** In two academic centers, postoperative outcomes of patients undergoing pancreaticoduodenectomy from 2002 to 2014 were prospectively recorded. Patients presenting with metabolic syndrome [defined as at least three criteria among overweight(BMI ≥ 28 kg/m2), diabetes mellitus, arterial hypertension and dyslipidemia] were compared to patients without metabolic *** Among 270 consecutive patients, 29(11%) presented with metabolic syndrome. In univariable analysis, patients with metabolic syndrome were significantly older(69.4 years vs 62.5 years, P = 0.003) and presented more frequently with soft pancreas(72% vs 22%, P = 0.0001). In-hospital morbidity(83% vs 71%) and mortality(7% vs 6%) did not differ in the two groups so as pancreatic fistula rate(45% vs 30%, P = 0.079) and severity of pancreatic fistula(P = 0.257). In multivariable analysis, soft pancreas texture(P = 0.001), pancreatic duct diameter nd BMI > 30 kg/m2(P = 0.041) were identified as independent risk factors of pancreatic fistula after pancreaticoduodenectomy, but not metabolic *** In spite of logical reasoning and appropriate methodology, present series suggests that metabolic syndrome does not jeopardize postoperative outcomes after pancreaticoduodenectomy. Therefore, definition of metabolic syndrome seems to be inappropriate and fatty pancreas needs to be assessed with an international consensual histopathological classification.

Clinical infection with varicella in both its’ forms, primary and reactivation, can be associated with a variety of complications. Cardiac complications, though very rare, have been associated with the primary form of varicella zoster and as such should be recognized in order to initiate early treatment and prevent morbidity and mortality. However, cardiac complications have not been described in association with the reactivation form of varicella. We report a case of an adult immunocompetent male who presented with herpes zoster complicated by pericarditis with pericardial effusion and a positive varicella zoster virus (VZV) polymerase chain reaction (PCR) in pericardial fluid.

In this paper, we propose MAMnID, a mobile agent-based model for networks incidents diagnosis. It is a load-balance and resistance to attack model, based on mobile agents to mitigate the weaknesses of centralized systems like that proposed by Mohamed Eid which consists in gathering data to diagnose from their collecting point and sending them back to the main station for analysis. The attack of the main station stops the system and the increase of the amount of information can equally be at the origin of bottlenecks or DDoS in the network. Our model is composed of m diagnostiquors, n sniffers and a multi-agent system (MAS) of diagnosis management of which the manager is elected in a cluster. It has enabled us not only to reduce the response time and the global system load by 1/m, but also make the system more tolerant to attacks targeting the diagnosis system.

Transmissible venereal tumor (TVT) is a widely reported transplantable tumor in dogs, with no breed or sex predilection and with a low metastatic rate. This retrospective study conducted from 2005 and 2011 sought to evaluate the total number of TVT cases, and to report extragenital TVT lesions in dogs from the small tropical island of Grenada, West Indies. Evaluation of the biopsy and necropsy specimens from dogs with TVT was carried out by cytological and histopathological methods. In the present study, we observed a total of 78 dogs with TVT, comprising 40 male and 38 female dogs. Most cases were from dogs between 3 and 6 years;less frequently from older dogs (over 6 years) or younger dogs (1 - 2 years of age). In the present study, we report 15 cases (19.2%) of dogs with TVT in extragenital sites. Tumors were noted in the nasal cavity, eye orbit, spleen, liver, skin, ribs, subcutaneous, and submandibular, cervical and inguinal lymph nodes. There was also evidence of metastasis to the ovaries in 2 dogs. The most interesting finding was the presence of extragenital lesions without primary genital involvement in 4 cases (5.1%). Our findings emphasize the need to consider TVT on the list of differential diagnosis for masses in extragenital sites in dogs from geographic regions where TVT is prevalent.
