The Description of a Marine Fishes Cestode with the Discussion on the Third Nutrition Manner Gonghuang Cheng, GonGSH un Cheng American Journal of Zoological Research. 2014 2 (2). doi: 10.12691/ajzr-2-2-1 Keywords: cetoda, anchistrocephalus, animal nutrition, phytotrophy, heterotrophy, autotrophy Context: The authors investigated the marine fish cestodes in Zhanjiang 2000s at the coast of South China Sea. Many specimen of fish cestodes were collected, in which 27 samples collected from Navodon sp. are belonging to Genus Anchistrocephalus. The description of the cestode is as follows: middle worm, with a length of 10~382, proglottids numbered 35~931. Biggest width of the worm is 4.28. Scolex Rectangle, measured 0.478~0.612×0.350~0.484, with an apical disc, 0.197~0.313 near to the disc there are 10 rows of staggering hooks. Neck absent. Taped structure with distinct segmentation, the ratio of width and length of proglottid is not definite. Immature proglottid measured 0.201~0.823×0.331~1.187, while mature proglottids 0.473~0.909×0.829~2.561, gravid proglottid 0.196~0.702×1.483~3.505. Male organs: numerous testes irregularly shaped located in medullary abdomen both side and gathered in the end of the proglottid; cirrus sac is liking a long peared shaped, 0.447 ~ 0.535×0.123 ~ 0.145, cirrus pore alternated both sides irregularly. The cirrus slender, measured 0.330~0.434, with denseness spines on it. The diameter of cirrus is 0.063, open hole, 0.048. Female organs: ovary posterior, measured 0.290~0.388×0.190~0.308, medullary. Vitelline glands distributed both side near the discharge tube follicle, the uterus is tube like, opens in the central abdomen and did not contact the genital pore, numbered 39~84, measured 0.052 ~ 0.062×0.031~ 0.037. For lacking documents the species cannot be identified to species. The special condition of the cestode is that it discharge eggs rather than gravid proglottids and the empty proglottids keep on the body and are absorbed gradually. And this would be a new nutrition manner for animalia,and it is called “autotrophy” by the authors. As we know animal nutrition manners are mainly phytotrophic and heterotrophic at present shown by all scientific documents, but the authors stated here the third one which is suggested to be named as autotrophy (self-absorption) based on the research. Many animals such as sea squirt, frog even human being carried on this nutrition manner. Abstract Full Text (PDF) [Epub] Full Text (HTML)

Application of Quadruple Multiplex PCR Detection for Beef, Duck, Mutton and Pork in Mixed Meat Haining He, Xia Hong, Yusheng Feng, Yongsong Wang, Jin Ying, Qi Liu, Yingwen Qian, Xinkui Zhou, DonGSH uai Wang Journal of Food and Nutrition Research. 2015 3 (6). doi: 10.12691/jfnr-3-6-6 Keywords: multiplex PCR; beef; duck; mutton; pork; identification Context: In this study, we have developed quadruple multiplex PCR assay for meat (beef, duck, mutton and pork) in processed meat products. By mixing four primers in appropriate ratios could be identified by the PCR. A forward primer was designed on a conserved DNA sequence in the mitochondrial ND2 and 16S rDNA gene in sheep and duck genes, and reverse primers on species-specific DNA sequences for each species. PCR primers were designed to give different length fragments from the four meats. The products showed species-specific DNA fragments of 116, 212, 177 and 322 bp from beef, pork, mutton and duck. Optimal PCR conditions were established. The assay sensitivity under these conditions was 0.1ng, and its specificity was 100 %. The results of the study suggest that PCR represents a simple, efficient test method as a practical alternative for the rapid detection and identification of meat.

Discrete Time-Cost Tradeoff Model for Optimizing Multi-Mode Construction Project Resource Allocation ShuanGSH uang Nie, Jihong Gao American Journal of Civil Engineering and Architecture. 2015 3 (3A). doi: 10.12691/ajcea-3-3A-2 Keywords: project scheduling, resource-constrained project scheduling problem, resource leveling, genetic algorithm, optimization, strength pareto evolutionary approach II Context: The project scheduling and resource allocation problems have been studied using different optimization methods. The resource leveling problem was proposed to reduce the resource fluctuation and was always studied independently resource constraint problem. For example, resource-constrained project scheduling problem (RCPSP) was proposed to optimize scheduling under resource constraints. This research proposed a new model which integrates the resource leveling problem and resource-constrained time-cost tradeoff problem. The evolutionary multi-objective optimization technique, strength Pareto evolutionary approach II (SPEA II) was applied to calculate the Pareto front of time and cost. The resource leveling measured by the metric, resource release/re-hiring, was converted to resource cost. The analysis of the time complexity of the model showed that the runtime of the algorithm was polynomial times of the number of activities. The results of case testing showed that the model was reasonably accurate in comparison with a proposed baseline model. Abstract Full Text (PDF) [Epub] Full Text (HTML)

Monirul Islam, G.M. Sala Uddin Journal of Food and Nutrition Research. 2016 4 (1). doi: 10.12691/jfnr-4-1-7 Keywords: radiation, moisture, carotenoid, ascorbic Acid, IAEA, microbes Context: Food was, is and perhaps will be the greatest concern for humankind due to outbreak of foodborne diseases and for sake of good health. Food suppliers and/or industries follow various techniques for ensuring their food safety. One way to overcome this situation is the use of ionizing radiation applied to food for assuring microbial as well as nutritional safety concern. Here apple, grape, guava, pear and plum sample were treated with 0.5, 1 and 1.5 kGy radiation from a 60Co gamma irradiator. Changes of the native microflora and some specific nutritional and physico-chemical properties of irradiated fruit were determined. It was observed that 0.5 kGy irradiation dose reduce a significant amount of microbial load compared to control and 1 kGy irradiation reduce microbial load under the sanitary level recommended by International Atomic Energy Agency (IAEA).Samples treated with 0.5kGy were healthier acceptance than samples treated by 1kGy and 1.5kGy during the six successive days of storage. Moisture content more than 90%were found in apple, plum and pear and statistically no significant changes (p<0.05) were observed in irradiated samples compared to the non-irradiated samples. At 1.5 kGy carotenoid content was increased 45.7926% in apple. Statistically significant increase of total carotenoid was observed in plum at 0.5, 1 and 1.5 kGy but the decrease in apple, pear and guava at dose 1 and 1.5 kGy. Thus, insignificant variation of ascorbic acid content was observed at radiation dose 1±0.5kGyin fresh cut fruit produce. Abstract Full Text (PDF) [Epub] Full Text (HTML)

Methods: A total number of 371 clinical cases, from January 2012 to October 2014 in our hospital, were analyzed which covered 198 patients underwent the laparoscopy in radical resection and 173 cases in open radical resection. A retrospective analysis was proceeded by comparing the general information, surgery performance, pathologic data, postoperative recovery and complicetions as well as long-term survival to investigate the diversity of immediate and long-term clinical outcomes of laparoscopic radical operation. Results: All patients have successfully completed the surgery, which includes 198 cases of laparoscopic rectal resection, 173 cases in open radical resection. There were no statistically significance differences between gender, age, height, BMI, staging and associated with other diseases in two groups. The operative time of rectal resection under the Laparoscopic was shorter than open radical resection (120±30minvs 105±39min), with no statistical significance(P＞0.05).In the laparoscopy surgery, the amount of bleeding is less than open surgery (50±20ml VS 200±25ml), and the difference was statistically significant. In the laparoscopy surgery, the length of incision is shorter than open surgery (5.1±0.23cm VS 13.5±1.34cm), and the difference was statistically significant. The hospitalization length in laparoscopy surgery and open surgery was significant difference (P＜0.01). Conclusion: In contrast to open surgery group, the laparoscopy surgery group expericenced less bleeding, shorter incisionand hospitalization length. The incident rate of perioperation complications in laparoscopy surgery and open surgery groups were not significant different. The colorectal cancer resection with laparoscopic has less trauma and can recover quickly, so it can achieve the same radical effect just like laparotomy and worth to be promoted in the Clinical application.
