The study was aimed to determine the antioxidant contents and the effect of different blanching times (5 min, 10 min, 15 min and 20 min) on antioxidant contents of three different selected fresh vegetables. Three different types of vegeta- ble were used namely Amaranthus specie locally known as spinach, namely “tete”, (Celosia argentea), soko, (Solonum nodifiorum) and odu, (Telfeira occidentalis) were analyzed for their antioxidant contents. The analysis revealed that raw vegetables have the highest amount of antioxidant contents. Telferia occidentalis had the highest antioxidant content followed by Solonum nodifiorum. It was observed that blanching time had an adverse effect on the antioxidant contents of the blanched vegetables. The antioxidant contents of tete, soko and odu were significantly decreased (p < 0.05) after blanching.

Acute symptomatic hyponatraemia following sodium picosulfate/magnesium citrate as bowel preparation for colonoscopy—A case series

引用

Case Reports in Clinical Medicine 2014年第2期3卷 101-104页

作者： Hannah Forde Triona o’Shea Colin Davenport Diarmuid Smith Academic Department of Endocrinology and RCSI Medical School Beaumont Hospital Dublin Ireland

oral purgatives such as sodium phosphate and sodium picosulfate/magnesium citrate (Picolax) combinations are commonly used as a preparation step for colonoscopies in Ireland. These substances can occasionally cause significant electrolyte disturbances including hyponatraemia. Although this is a rare complication of undergoing a colonoscopy, if not treated promptly and appropriately, these electrolyte abnormalities can be associated with life threatening complications. We report cases of symptomatic hyponatraemia in three women aged 65-75 years, following ingestion of Picolax in preparation for a colonoscopy. All three patients had documented previously normal electrolytes and all three required hospital admission for management of their electrolyte disturbance. However, the clinical presentations were variable and depended upon the severity of the hyponatraemia. Patient 1 presented with nausea and vomiting 7 hours post Picolax ingestion. Plasma sodium was 124 mmol/l. She was diagnosed with mild symptomatic hyponatraemia, and treated with anti-emetics and slow intravenous infusion of 0.9% Saline. Patient 2 developed acute confusion 8 hours following ingestion of Picolax. Plasma sodium was 120 mmol/l and she was clinically dehydrated. She was also treated with intravenous 0.9% Saline. Patient 3 presented with seizures and reduced GCS, 48 hours post Picolax ingestion. Plasma sodium was 111 mmol/l. As she had severe life threatening hyponatraemia with seizures, she was treated with boluses of 3% hypertonic saline. It is recommended that cleansing agents should be used with caution in the elderly, patients with a low seizure threshold, patients with renal impairment, liver cirrhosis, heart failure, and patients on diuretics. These patients should have plasma sodium monitored pre- and post-colonoscopy to ensure early detection of hyponatraemia if present, and to initiate prompt and appropriate management to prevent the serious complications associated with hyponatraemia.

Evaluation of the Quality of Life in Pre- and Post-operatory in Patients Submitted to Surgical Treatment of Reflux Disease and Hiato Hernia

引用

Surgical Science 2023年第6期14卷 441-455页

Gastroesophageal reflux disease affects 40% of the population in industrialized countries. GERD has a negative impact on the quality of life of affected patients. Although PPIs induce a good response in the control of symptoms, the need for prolonged use of the medication and the fact that more than a third of the patients have symptoms even after its correct use, make surgery, an alternative for the treatment of the disease. The aims of this study were to compare the quality of life related to GERD before and after MIS surgical treatment of GERD and/or hiatus hernia, and to analyze the results and complications of the MIS treatment of GERD. Methods: For retrospective analysis, the electronic database of patients with indications for surgical treatment due to GERD and/or patients with sliding or paraesophageal hernias was examined. The study included patients from Hospital Universitário Gaffrée e Guinle and the Postgraduate Course in General Surgery at PUC-Rio (Rio de Janeiro, Brazil) who underwent surgery using video laparoscopy or robotic surgery between January 2013 and March 2020. This is an observational, longitudinal, descriptive study with retrospective analysis of the data. Surgical treatment was indicated due to incomplete response to clinical treatment, young age with persistent symptoms, or complications of GERD. Patients with hiatus and/or paraesophageal hernia with indication for surgical treatment were included. Results: The study evaluated 160 patients who underwent anti-reflux surgery by laparoscopic or robotic surgery in the period from 2013 to 2020. A total of 88 women and 72 men were operated, mean 46.6 ± 13.7 years. An improvement in the preoperative QS-GERD scores compared to the postoperative scores was observed (27.56 ± 10.93 vs 1.4 ± 2.47, p onally, it was observed that there was no association between worse prognosis and failure rate with gender, sex, age, body mass index, surgical technique, or the number of sutures on the fu

尼日利亚反腐败政策研究

尼日利亚反腐败政策研究

腐败是当今世界上人类面临的最大的问题;它是国家经济孕育的―病毒‖。它是所有人类所面临的所有问题产生的原因，包括贫穷，疾病，可利用资源的稀缺，良好治理的缺失，暴力，谋杀，抢劫等。腐败的破坏性影响已经引起了国家和国际政府... 详细信息

腐败是当今世界上人类面临的最大的问题;它是国家经济孕育的―病毒‖。它是所有人类所面临的所有问题产生的原因，包括贫穷，疾病，可利用资源的稀缺，良好治理的缺失，暴力，谋杀，抢劫等。腐败的破坏性影响已经引起了国家和国际政府的关注，并介绍反腐败措施以遏制腐败。尼日利亚作为世界一国，也是被腐败侵蚀最严重的国家，在1999恢复了民主统治之后，开始了反腐败政策的制定以解决其前所未有的腐败问题。因此，本研究试图分析这些反腐败政策，指出其所取得的成果，以及政策的优缺点。分析表明，尼日利亚的腐败非常活跃，影响着社会的方方面面。腐败的所有类型和形式在尼日利亚皆存在，更易于理解和分析。腐败类型分为三种，为政治重叠腐败，官僚腐败，经济/金融腐败。针对这种高比例腐败，尼日利亚政府提出的反腐败的政策或措施，是及时的，对遏制腐败有巨大效力。容易滋生腐败的系统的每部门都有法律来规范其运行以保证透明和负责任。尼日利亚的反腐败机制是完善的，但缺乏实施这些机制强有力的政治意志。反腐败机构遭遇了来自政治领导人的政治干预，这阻碍了反腐败机构履行其职责，并因此降低他们的成功和成就水平。为了保证反腐败机构的功能和实现目的，这也是建立反腐败机构的初衷，赢得反腐败斗争的成功，本文的第五章提出了对尼日利亚的反腐败战略的适用的借鉴，其中一个，也被称之为反腐败公式，即政治意志+反腐败政策+反腐败机构+特殊的反腐败法庭+死刑–腐败=良好的治理。应用这些?必须非常严肃的和强有力，遵从国家的宪法。此外，反腐败不是可以通过一个单一国家的努力完成的，而要结合其他国家的经验教训;因此从新加坡和博茨瓦纳的反腐举措的成功故事中总结经验教训。本文研究由五章构成：第一章为研究的概述，问题陈述（研究问题），研究的意义，研究方法等。本研究采用探索性和描述性的定性研究方法来分析所收集到的数据。本文的数据主要来自二手资料，包括出版报纸，书籍和期刊文章，以及政府的政策文件等。腐败作为一种普遍的现象，还没有公认的定义，因此第二章在腐败的不同理论，方法和表现的基础上，进行了腐败的概念性分析。第三章论述了尼日利亚的腐败现状，以及反腐败政策研究的出台。第四章分析了通过私人和国际措施来与腐败斗争两方面分析反腐败政策。第五章分析了前面章节讨论的问题的研究发现，从而回答了研究问题，同时借鉴其他国家反腐败的举措，得出结论与建议。

Properties of Rattan Cane Reinforced Concrete Facade Subjected to Axial Loading

引用

Journal of Civil Engineering and Architecture 2011年第11期5卷 1048-1052页

作者： J. o. Akinyele F. A. olutoge Department of Civil Engineering University of Agriculture Deparment of Civil Engineering University of Ibadan

The use of steel reinforced concrete facade is gradually becoming unpopular because of the damage caused to the elements as a result of corrosion of the steel reinforcement. It is now possible to build lightweight and slender concrete structures which are invulnerable to corrosion with the use of fiber reinforcements, which are gradually replacing the corrosion prone steel. This paper describes the construction of faqade panels made of rattan cane reinforcements and steel reinforcements, ten number model sized elements of area 0.15 m2 and a depth of 40 mm were considered, with five panels for each reinforcement type. The elements were subjected to incremental load of 1 kN until failure occurred. Deflections were measured for each element, and crack width was measured at failure load. The results for both types of reinforcements when compared showed the rattan cane reinforced panels failing earlier than the steel reinforced panels. However a lower defection and crack width was recorded in the rattan cane reinforced panel. This paper concludes that the lower crack width formed after failure in the rattan cane reinforced panel gave it advantage over the steel reinforced panel, since it has lower space for the ingress of water which is the main agents of corrosion.

Using HoMo Field Ionization Model, the tun-neling probabilities and the theoretical threshold intensities of the field ionizations of acetylene, ethylene, and ethane in intense laser field are calculated. C2H2, C2H4, and C2H6 were irradiated by 800 nm, 100 fs laser pulses with the intensity range of 1013—1014 W/cm2. A ToF-mass spectrometer was coupled to the laser system and used to experimentally in-vestigate the field ionization of these molecules. The experi-mental ionization threshold intensities are obtained. The calculating results of the three molecules agree well with the experimental results, indicating that HoMo Field Ionization Model is valid for the ionization of polyatomic molecules in intense laser field.

Design, Microwave Assisted Synthesis of Some Schiff Bases Derivatives of Congo Red and Conventional Preparation of Their Structurally Reversed Analogous Compounds

引用

International Journal of organic Chemistry 2021年第1期11卷 35-45页

作者： Nashwan o. Tapabashi Nihad I. Taha Marwa El-Subeyhi Collage of Pharmacy University of Kirkuk Kirkuk IRAQ Collage of Science University of Anbar Ramadi IRAQ

This work contributes to the improvement of the azo group which has outstanding electron donating capability and serves as excellent ligands in the field of coordination chemistry. The authors of this research deal with the microwave irradiation synthesis of some new Schiff bases derived from the biologically effective and photoactive Congo red [Ia-g]. The design and preparation of the structurally reversed analogous compounds to the above compounds [IIIa-d] were accomplished using the conventional chemical methods by keeping the benzidine moiety of Congo red as the nucleus of the synthesized compounds, doubling the number of the azo groups and inverting the way of their conjugation order with the azomethine groups. The structures of the newly prepared compounds were established on the basis of their FTIR and H1 NMR spectral data.
