The present paper deals with the development of a modular, flexible and structured block to block approach for the study of regulators by implementing the different blocks on a DSP （digital signal processor）. The proposed low-cost approach has been applied and validated by the implementation of an industrial regulator in a real time hardware-in-the-loop simulation of a mixed islanded power network including precise models of the hydraulic system. The studied network is constituted of three different types of electrical power generation systems and a consumer.

Thirty Trichoderma strains representing 15 species within the genus have been screened for extracellular production of chitinolytic enzymes in solid substrate fermentation (SSF). *** IMI 92027 (=ATCC 36838) gave the highest yield (5.0 IU/g dry matter of substrate) after 3 days of fermentation on wheat bran-crude chitin (9:1 mixture) medium. The optimum moisture content (66.7%), chitin content (20%), initial pH of the medium (2-5) and time course (5 d) of SSF were determined for strain IMI 92027. No significant effect of different N and P additives was found on the chitinase yield in wheat bran-chitin mixture medium. Cellulase, xylanase, alpha-amylase and beta-xylosidase activities were also detected. The pH and temperature optima of chitinase complex of *** IMI 92027 was found to be at 4.5 and 55 ℃, respectively. The enzyme totally lost its activity at 70 ℃ in 5 min in the absence of the substrate but retained about 15% of its initial activity even at 70 ℃ after incubation of 60 min in the presence of SSF solids (residual substrate and fungal mycelium). Purification of protein extract from the SSF material revealed high chitinolytic activities between pI 5.9.-4.8 where N-acetyl-β-D-hexosaminidase and chitinase peaks have been found in the same pI range. Chitinase peaks could be described at least at four pI values: pI 5.9; 5.6; 5.3 and 4.8 while at least four main N-acetyl-β-D-hexosaminidase peaks could be separated at pI 6.0 and 5.1 and at more basic isoelectric points of 7.2 and 8.0. Two chitinases with 43.5 kDa and 30 kDa were purified at acidic isoelectric point.

The present work analysed the chain of events involved in alpha - 2 - adrenoceptor - initiated gastric mucosal defense. Methods Gastric damage was induced by ethanol. Gastric acid secretion was measured in pylorus ligated *** were given either intracerebroventricularly （icv.） or intraperitoneally （ip.）.Results: Rilmenidine - alpha - 2/11 - imidazolinereceptors agonist - inhibited the ethenol - induced lesion （ED50:2 nmol/ kg ip.,6 pmol/rat icv.）. Yohimbine,prazosin,ARC 239 （icv.）（alpha-2B - adrenoreceptor antagonists） and the opioid receptor antagonist naloxone inhibited the gastroprotective effect. The gastroprotection was also blocked by NMDA receptor antagonist dizocilpine and NO synthase inhibitor L - NNA （icv.）. Conclusion: Activation of central alpha - 2B - adrenoceptor subtype initiates an opioid - excitatory amino acid - NO - mediated process resulted in gastric mucosal protection.

Asian Journal of Andrology 2009年第6期11卷 741-745页

The purpose of this study was to investigate the effects of an elevated hydrostatic pressure of hydrocele on the structural integrity and steroid receptor expression pattern of the appendix testis in children. Twenty-six testicular appendages were obtained from boys （aged between 13 and 79 months, mean 40 months） who underwent surgical exploration because of hydrocele or congenital inguinal hernia. The tissue sections of testicular appendages were stained with hematoxylin-eosin. Immunohistochemistry and immunofluorescence laser microscopy were performed using monoclonal mouse anti-human receptors against androgen and estrogen receptors. Patients were divided into three groups： group A （n = 8） represented patients with groin hernia without hydrocele, who served as control group; group B （n = 7） represented patients with communicating hydrocele; and group C （n = 11） represented patients with noncommunicating hydrocele. The tissue sections of appendix testis expressed both androgen and estrogen receptors in all patients in groups A and B, and epithelial destruction was not present. The presence of androgen receptor （two of 11, P 〈 0.001） and estrogen receptor （four of 11, P = 0.006） was lower and the number of appendix testes with epithelial destruction was higher （eight of 11, P-- 0.001） in group C. We demonstrated that groin hernia and communicating hydrocele did not influence the receptor expression pattern and the anatomic structure of testicular appendages, whereas noncommunicating hydrocele caused damage as indicated by the absence of steroid receptors and destruction of the epithelial surface. A better understanding of the physiological role of testicular appendages may change the indications of surgical treatment in patients with noncommunicating hydrocele.

AIM To evaluate the presence of submucosal and myenteric plexitis and its role in predicting postoperative *** Data from all patients who underwent Crohn's disease(CD)-related resection at the University of Szeged, Hungary between 2004 and 2014 were analyzed retrospectively. Demographic data, smoking habits, previous resection, treatment before and after surgery, resection margins, neural fiber hyperplasia, submucosal and myenteric plexitis were evaluated as possible predictors of postoperative recurrence. Histological samples were analyzed blinded to the postoperative outcome and the clinical history of the patient. Plexitis was evaluated based on the appearance of the most severely inflamed ganglion or nerve bundle. Patients underwent regular follow-up with colonoscopy after surgery. Postoperativerecurrence was defined on the basis of endoscopic and clinical findings, and/or the need for additional surgical resection. RESULTS One hundred and four patients were enrolled in the study. Ileocecal, colonic, and small bowel resection were performed in 73.1%, 22.1% and 4.8% of the cases, respectively. Mean disease duration at the time of surgery was 6.25 years. Twenty-six patients underwent previous CD-related surgery. Forty-three point two percent of the patients were on 5-aminosalicylate, 20% on corticosteroid, 68.3% on immunomodulant, and 4% on anti-tumor necrosis factor-alpha postoperative treatment. Postoperative recurrence occurred in 61.5% of the patients; of them 39.1% had surgical recurrence. 92.2% of the recurrences developed within the first five years after the index surgery. Mean disease duration for endoscopic relapse was 2.19 years. The severity of submucosal plexitis was a predictor of the need for second surgery(OR = 1.267, 95%CI: 1.000-1.606, P = 0.050). Female gender(OR = 2.21, 95%CI: 0.98-5.00, P = 0.056), stricturing disease behavior(OR = 3.584, 95%CI: 1.344-9.559, P = 0.011), and isolated ileal localization(OR = 2.671, 95%CI: 1.033-6.
