Background: Emergence agitation (EA) is a common phenomenon observed in pediatric patients following general anesthesia. This study aimed to assess the efficacy of propofol and fentanyl in preventing EA and to compare their associated complications or side effects. Methods: This prospective randomized observational comparative study was conducted at Dhaka Medical College Hospital from July 2013 to June 2014. The study aimed to evaluate the effects of propofol and fentanyl on EA in children aged 18 to 72 months undergoing circumcision, herniotomy, and polypectomy operations. Ninety children were included in the study, with 45 in each group. Patients with psychological or neurological disorders were excluded. Various parameters including age, sex, weight, American Society of Anesthesiologists (ASA) class, duration of anesthesia, Saturation of Peripheral Oxygen (SPO2), heart rate (HR), respiratory rate (RR), Pediatric Anesthesia Emergence Delirium (PAED) score, duration of post-anesthesia care unit (PACU) stay, incidence of laryngospasm, nausea, vomiting, and rescue drug requirement were compared between the two groups. Results: Age, sex, weight, ASA class, and duration of anesthesia were comparable between the two groups. Perioperative SpO2 and HR were similar in both groups. However, the PAED score was significantly higher in the fentanyl group during all follow-ups except at 30 minutes postoperatively. The mean duration of PACU stay was significantly longer in the fentanyl group. Although the incidence of laryngospasm was higher in the fentanyl group, it was not statistically significant. Conversely, nausea or vomiting was significantly higher in the fentanyl group. The requirement for rescue drugs was significantly higher in the fentanyl group compared to the propofol group. Conclusion: Both propofol and fentanyl were effective in preventing emergence agitation in pediatric patients undergoing various surgical procedures under sevoflurane anesthesia. However, propo

Sensing and Uptake of Nitrogen in Rice Plant: A Molecular View

引用

Rice science 2019年第6期26卷 343-355页

作者： md.saiful islam Department of Soil Science Patuakhali Science and Technology University Graduate School of Agricultural and Life Sciences The University of Tokyo

As a main feature of plant autotrophy, assimilation of inorganic nitrogen (N) is not only of fundamental interest to the crop, but also a crucial factor in crop productivity. N is the main plant mineral nutrient needed for chlorophyll production and other plant cell components (proteins, nucleic acids and amino acids). I highlighted the novel aspects of N responsive sensors, transporters and signaling molecules recently identified in the monocot rice plant, and discussed their potential roles in N sensing and transporting. Furthermore, over the last couple of years, N sensing has been shown to be affected by different external factors, which act as local signals to trigger systemic signaling coordinated by long-distance transport or mobile signals in plant body. Understanding of this complex regulatory network provides a foundation mechanism for the development of novel strategies to increase the acquisition and transportation efficiency of nitrogen under varying N conditions for rice production.

The assurance of corporate sustainability reporting has long been a controversial *** management and suppliers are routinely accused of violating principles ofsustainability, an important exercise in public accountability. This thesis responds to recent callsfor an analysis of the process by which the violation takes place. Integrating elements of neo-institutional theory and arena concept, the thesis provides a detailed study of the sustainablestrategy of H&M.This paper provides a thorough description of various threats to the sustainabledevelopment of H&M, such as their cotton frond problem, transport problem, employees training,customer dealings, etc. After that, the paper provides an account of H&M’s effort to seek asolution package to these threats, which together is represented as H&M’s sustainability *** the solution efforts are: they have their own sustainable strategy department, in thiswhich H&M tries to improve itself and resolve their sustainability problems;they are doing a lotof social work, like children education investment, employee training, thus making muchpositive contribute to the community in which it operates. This paper also provides informationon the result of H&M’s sustainability strategy, and draws some lessons from the overall case,which may prove meaningful to other similar clothing companies.

Histopathological changes in the diabetic rat organs(pancreas, liver, heart, kidney and spleen) were also observed after the 14 days of treatment with the ***: Oral administration of methanolic extracts of S. cumini seeds(100 and 200 mg/kg body weight), with gliclazide as a positive control(25 mg/kg), showed beneficial effects including lowering blood glucose levels(P < 0.001), improved heart and liver functions, and hyperlipidemia due to diabetes. At 200 mg/kg, the extracts reversed cardiac and liver damage caused by ***: In addition to the anti-hyperglycemic activity of methanolic extracts of S. cumini seeds, the extracts demonstrates potential to minimize cardiac and hepatic complications.

Pabna is one the most densely populated town with poor transport infrastructure in Bangladesh. Here huge pedestriangathers in roads and intersections in CBD （Central Business District） area mainly for commercial and business purposes. At present,pedestrian facilities are one of the greatest challenges in terms of traffic and safety for the urban dwellers. The footpath, zebra rossing,road intersection, walkways, parking and other facilities are the major part of road transportation system as well as pedestrianfacilities and people have to pass walking distance to reach their destinations, before and after use of transport mode. For instance,this paper tries to emphasize the problems of pedestrian facilities and to explore the qualitative level of comfort for the pedestrians ofthree selected intersections namely Traffic More, Indra More and Nimtola More in CBD area of Pabna Municipality through primaryand secondary data. However, about 60% trips are making on foot every day, but the pedestrians are facing many problems whileusing the walkways. Pedestrian crossing behaviors were also observed by using pedestrian volume survey and the survey exploresthat pedestrian crossing rate at these intersections is about 5,000 to 7,000 per hour at a peak period and average 15% to 25% illegalcrossing occurs at those intersections. The physical observation and data from the questionnaire survey also indicate that informalbusiness on the footpath, illegal parking, illegal vendor on walkways, physical obstacle, poor lighting facilities and geometricproblem of the road intersection makes uncomfortable situations for the pedestrian day by day.
