Here, we summarise the experience of our first series through 52 cases of prostate cancer treated by robot-assisted radical prostatectomy (RARP) in the Department of Urology of Binh Dan Hospital, from December 2016 to September 2017, to study the learning curves of this procedure. In this clinical comparative study, 52 patients diagnosed with prostate cancer (clinical stage T1 to T3) received RARP with and without nerve sparing as well as standard pelvic lymphadenectomy. Patients were divided into 4 groups according to their surgeon (surgeons A, B, C, and D, with 22, 12, 10, and 8 patients, respectively) for comparison. Research variables were cancer stage, pre- and postoperative prostate-specific antigen (PSA) serum levels, Gleason scores, lymph node metastasis, estimated blood loss, surgery time, urinary incontinence, hospital stay, and complications. Mean age, PSA, and stage of cancer were statistically similar (p>0.3). Operative times were 194.55, 269.17, 236.00, and 306.88 min, respectively (p<0.01). Mean estimated blood losses were 363.64, 404.17, 322.22, and 253.75 ml, and were significantly different (p<0.01). Nine patients required blood transfusion. The lengths of hospital stay were 5.73, 12.92, 5.10, and 6.13 days, and were not similar among groups (p<0.05); however, drainage times and complication rates between groups (p<0.01) were statistically significant. The optimal learning curve for operative times was achieved after 20 cases. Our initial RARP results were relatively strong, suggesting that surgery could be safely performed with acceptable complications.","PeriodicalId":23548,"journal":{"name":"Vietnam Journal of Science, Technology and Engineering","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80149435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shrimps were administered either B. aquimaris SH6 spores at 1×106CFU g-1 pellet (SH6 group) or a mixture of SH6 and B. subtilis SH23 spores at 5×105 CFU g-1 pellet for each strain (SH6-SH23 group). After a 28-day feeding period, the number of SH6 spores in the gut of whiteleg shrimp in the SH6 group and the SH6-SH23 group were 5.7×103 CFU gut-1 and 7.7×103 CFU gut-1, respectively. The total bacterial population of these two experimental groups increased about 10-75% compared to that of the control group. The astaxanthin level and red colour score were the highest in the SH6-SH23 group (1.66 μg.g-1 shrimp; 28-29), followed by the SH6 spore group (1.42 μg.g-1 shrimp; 27-28), and were the lowest in the control group (0.61 μg.g-1 shrimp; 26-27). Nevertheless, the growth rate of shrimps was similar (7.8-8%) among the three groups. In conclusion, feed supplements containing SH6 and SH23 spores co-effectively improved live counts and diversity of microbiota in shrimp guts, as well as improved astaxanthin level and red colour of whiteleg shrimps.","PeriodicalId":23548,"journal":{"name":"Vietnam Journal of Science, Technology and Engineering","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74451861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of remote sensing applications to analyse the impacts of these changes plays an important role in the managing the sustainability of theriver basin. This paper introduces a solution for analysing the impacts of LC changes on the water balancein the upstream catchment of the Dong Nai river in Lam Dong province. Landsat images were used for mapping and monitoring major changes over the last 20 years. Rainfall and water discharge data was collected from the local hydrometeorological stations to identify the impacts of the LC changes on the runoff in the catchment area. The results show that the forest area was reduced by more than 223,576 ha (23%). The main changes were an increase in the agricultural area from 18.2 to 31.3% and in water bodies from 0.9 to 2.2%. The latter was due to hydropower development projects in the catchment area. The LC changes caused by the changes in the hydrological conditions of the river basin have had a significant impact on water resources. The identification of the main LC changes in the catchment area could be useful for establishing a policy to protect the headwater forests and mitigate against future impacts.","PeriodicalId":23548,"journal":{"name":"Vietnam Journal of Science, Technology and Engineering","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91302399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pilot system was designed to include a series of processes, such as aeration, sedimentation, sand filtration, and adsorption, using the iron-rich adsorbent and activated carbon from coconut shells. The pilot system was tested with three operated modes. The results demonstrate that the treatment efficiency of the overall treatment processes was significantly higher than that of the traditional treatment system used by local people. After aeration, sedimentation, and sand filtration, the water quality was discovered to respond substantially in reducing iron by over 96% (from 8-12 mg/l to less than 0.3 mg/l) arsenic by 55 to 60%, but after iron-rich adsorbent, the concentration of arsenic decreased to less than 10 μg/l, which fulfills Vietnam National technical regulations concerning drinking water quality.","PeriodicalId":23548,"journal":{"name":"Vietnam Journal of Science, Technology and Engineering","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88735469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
