The main aims of this review were to understand the roles of gene therapy in the treatment and prevention of type 1 diabetes mellitus and I will discuss a brief history, approaches, vector types with the future of diabetes following clinical use. Type 1 diabetes mellitus is a metabolic condition that is identified by insufficient insulin development due to pancreatic damage to beta cells. Control, long life, and diagnosis of these metabolic disorders have become vital sources for many scientists and researchers. After 2000, the latest approaches to molecular medicine were introduced as one of the possible therapeutic options for diabetes type 1 diagnosis. Many genes have been reported as a clinical trial so that damaged genes can be treated and three main approaches shown about 50 years ago are islet transplantation, β cell regeneration, and insulin gene therapy to cure and prevent diabetes type. Treating diabetes through gene therapy can promise children and adolescents, but more clinical applications are needed to recognize it as a permanent route.
本综述的主要目的是了解基因治疗在1型糖尿病的治疗和预防中的作用,并将讨论其简史、方法、载体类型以及临床应用后糖尿病的未来。1型糖尿病是一种代谢疾病,由于胰腺细胞损伤导致胰岛素分泌不足。控制、延长寿命和诊断这些代谢紊乱已成为许多科学家和研究人员的重要来源。2000年以后,分子医学的最新方法被引入,作为1型糖尿病诊断的可能治疗选择之一。许多基因已被报道为临床试验,因此可以治疗受损基因,大约50年前显示的三种主要方法是胰岛移植,β细胞再生和胰岛素基因治疗,以治疗和预防糖尿病类型。通过基因疗法治疗糖尿病可以为儿童和青少年带来希望,但需要更多的临床应用来认识到它是一种永久性的途径。

The use of psychoactive substances for several reasons by commercial vehicle drivers has been documented as a major cause of increased incidences of traffic accidents globally. The study aimed at determining the prevalence of psychoactive substance use among Nigerian male commercial vehicle drivers randomly selected from the three major ethnic groups in Nigeria (Igbo, Hausa and Yoruba). A structured questionnaire which included data on sociodemographic status and psychoactive drug use history was introduced to all participants. Generic Multi-Drug Urine Dip Card Test Kit and Shimadzu chromatograph system (Shimadzu Corporation, Kyoto, Japan) were used for toxicological analyses. Out of the 264 Nigerian male commercial vehicle drivers who participated in this study, 111(42.0 %) had used illicit drugs in recent times, 55(20.8 %) took drugs for improved energy and 90(34.1 %) felt high after using illicit drugs. Marijuana was the most abused substance; 77(29.2 %) followed by benzodiazepine; 34(12.9) across all ethnicities studied. Across all ethnicities, HPLC revealed that the Hausa drivers had the highest concentration of psychoactive substances in their urine samples. These findings, reiterates the need for the Nigerian anti-drug agency to develop new strategies in conducting a repressive drug war and extending the same to bus stations.
商用车司机出于多种原因使用精神活性物质已被记录为全球交通事故发生率增加的主要原因。该研究旨在确定从尼日利亚三个主要族裔(伊博族、豪萨族和约鲁巴族)中随机选择的尼日利亚男性商用车司机使用精神活性物质的流行情况。向所有参与者介绍了一份包含社会人口统计状况和精神药物使用史数据的结构化问卷。采用通用多药尿浸卡检测试剂盒和岛津色谱仪(日本京都岛津公司)进行毒理学分析。在参与这项研究的264名尼日利亚男性商用车司机中,111名(42.0%)最近使用过非法药物,55名(20.8%)服用药物以改善精力,90名(34.1%)在使用非法药物后感到兴奋。大麻是滥用最多的物质;其次是苯二氮卓类药物77例(29.2%);34人(12.9人)。在所有种族中,HPLC显示豪萨司机的尿液样本中精神活性物质浓度最高。这些调查结果再次表明,尼日利亚禁毒机构需要制定新的战略,开展镇压性的毒品战争,并将其扩大到公共汽车站。

Warburgia ugandensis Sprague is one of the medicinal plants traditionally used to treat a number of diseases like asthma, cough, diarrhea, common cold, stomachache and toothache in Ethiopia. However, there is still insufficient information on the isolation and evaluation of bioactive compounds from this plant species. Extraction, purification and isolation of the stem bark of this plant by dichloromethane and chloroform as solvents afforded two sesquiterpenes; namely, WU-1 (ugandensidial) and WU-2 (cinnamolide-3β-acetate) respectively. The structural elucidations of these bioactive compounds were accomplished by using a variety of spectroscopic methods (IR, UV and NMR). The spectroscopic results compared with the reported data in the literature.

Impairment in testicular function can occur through perturbations in testicular oxidative stress markers and histology. Xylopia aethiopica (XE) is used to enhance fertility in males, but with information gap on its effect on testicular oxidative stress markers and histology. The present study assessed the effects of ethanolic stem bark extract of Xylopia aethiopica (EEXA) on testicular oxidative stress markers and histology of male albino rats. Sixty adult male albino rats (200g-250g) were randomly grouped into 4 (A-D) of 15 rats per group. The rats in the control group A (A1-A3) were administered per oral (p.o) with water (0.2 mL/day) for 15, 30 and 60 days respectively. The rats in groups B (B1-B3), C(C1-C3) and D (D1-D3) were administered p.o with EEXA (200, 400 and 800 mg/kg/day) for 15, 30 and 60 days respectively. The rats were anesthetized at the termination of EEXA administration and were dissected and testes removed. The testes were weighed and evaluated for oxidative stress markers and histology. Testicular weights were decreased in a dose and-time dependent fashion in EEXA-treated rats. Significant decreases in testicular superoxide dismutase, glutathione, catalase, and glutathione peroxidase levels with significant increases in malondialdehyde levels in a dose and time-dependent fashion were observed in rats administered with EEXA. Testicular histology showed cellular necrosis, degeneration and loss of interstitial tissues in rats administered with EEXA. This study observed that EEXA perturbed testicular oxidative markers and histology. Its use may impair testicular function.
睾丸功能损害可通过睾丸氧化应激标志物和组织学的扰动发生。埃塞俄比亚木杉(Xylopia aethiopica, XE)被用来提高雄性的生育能力,但其对睾丸氧化应激标志物和组织学的影响信息空白。本研究评估了木皮醇提物(EEXA)对雄性白化大鼠睾丸氧化应激标志物和组织学的影响。取成年雄性白化大鼠60只,体重200 ~ 250g,随机分为4组(a ~ d),每组15只。对照组A (a1 ~ a3)大鼠灌胃(0.2 mL/d),分别灌胃15、30、60 d。B组(b1 ~ b3)、C组(c1 ~ c3)、D组(d1 ~ d3)分别给药EEXA 200、400、800 mg/kg/ D,连续15、30、60 D。在EEXA给药结束时麻醉大鼠,解剖并切除睾丸。对睾丸进行称重并评估氧化应激标志物和组织学。eexa处理的大鼠睾丸重量呈剂量和时间依赖性下降。在给药EEXA的大鼠中观察到睾丸超氧化物歧化酶、谷胱甘肽、过氧化氢酶和谷胱甘肽过氧化物酶水平显著降低,丙二醛水平显著增加,且呈剂量和时间依赖性。大鼠睾丸组织学表现为细胞坏死、变性和间质组织丢失。本研究观察到EEXA对睾丸氧化标志物和组织学的影响。它的使用可能损害睾丸功能。

Dryopteris filix mas ( D filix-mas ) is wildly used in ethnomedicine for the management of rheumatoid arthritis, wounds and other diseases. We investigated the anti-oxidant activities of its leaf extract, and chromatographic fractions. The ethanol leaf extract was partitioned into four fractions; n-hexane, ethyl acetate, n-butanol and water. Ferric reducing anti-oxidant power (FRAP), 1, 1-diphenyl-2-picrylhydrazil (DPPH) and nitric oxide (NO) scavenging in vitro assays were carried out on the extract and fractions at 6.25, 12.5, 25, 50, 100, 200, 400 and 800 µg/mL. The most active fraction (ethyl acetate fraction) was further purified using chromatographic techniques to isolate its major compound whose structure was elucidated using ID nuclear magnetic resonance (NMR) and mass spectrometry. The ethyl acetate fraction produced the highest free radical scavenging activity among the other fractions. The fraction (VLC-E7) from which the bioactive compound, quercetin-3-O-αL-rhamnopyranoside , was isolated had the best FRAP and DPPH scavenging activities with EC 50 and IC 50 values of 88.81 ± 3.41 and 26.87 ± 0.24 respectively more than the ethyl acetate fraction. This study revealed that the polyphenol flavonoid, quercetin-3-O-αL-rhamnopyranoside could be responsible for antioxidant activity of ethno-medicinal property of D filix-mas leaf.
丝状鳞毛蕨(D filix mas)在民族医学中被广泛用于治疗类风湿性关节炎、伤口和其他疾病。我们研究了其叶提取物和色谱级分的抗氧化活性。将乙醇叶提取物分成四个部分;正己烷、乙酸乙酯、正丁醇和水。在6.25、12.5、25、50、100、200、400和800µg/mL的提取物和级分上进行了铁还原抗氧化能力(FRAP)、1,1-二苯基-2-苦基肼(DPPH)和一氧化氮(NO)的体外清除试验。使用色谱技术进一步纯化最具活性的组分(乙酸乙酯组分)以分离其主要化合物,其结构通过ID核磁共振(NMR)和质谱法阐明。乙酸乙酯部分在其它部分中产生最高的自由基清除活性。从中分离出生物活性化合物槲皮素-3-O-αL-鼠李吡喃糖苷的组分(VLC-E7)具有最佳的FRAP和DPPH清除活性,EC 50和IC 50值分别比乙酸乙酯组分高88.81±3.41和26.87±0.24。本研究表明,多酚类黄酮槲皮素-3-O-αL-鼠李吡喃糖苷可能对金丝桃叶的民族药用特性具有抗氧化活性。

The study of the relationship between starch addition to biodegradation of bioplastics has been carried out. This study aims to understand the biodegradability of chitosan-based bioplastics with additional cassava peel starch on soil and river water media. This research was conducted through four stages, namely making starch from cassava peel waste, making bioplastics using the blending and castingwet processes method with variations of starch 5, 10, 15 and 20 ml. Testing physical mechanical properties including water resistance, thickness, tensile strength, elongation, and modulus young. Testing the characteristics of bioplastics functional groups was carried out using FTIR (Fourier Transform Infrared) and biodegradation testing of bioplastics carried out on soil and river water media. The results of bioplastics research with variation 5 ml produce good mechanical physical properties. Bioplastics produced water resistance value of 45.03%, thickness of 0.0190 mm, tensile strength of 49.93 MPa, elongation of 3.068% and Young modulus of 1627.63 MPa. Bioplastics biodegradation test was observed by measuring the decrease in sample mass. The biodegradation test results in soil and river water media respectively showed a decrease in bioplastic mass up to 63% and 54%. The biodegradation rate of the calculation results on soil media is −0,1502 and in river water media is −0,0948.

The metal casting industry, Nitikan is a micro business whose production process is carried out manually. The equipment used is simple and without considering the user's health. This can be seen in the product finishing process that uses a sanding machine. The equipment is not designed according to the user's posture so the operator bends in doing work movements, of course this is very risky to experience lower back pain injuries. This study aims to analyze the work activities of the finishing process using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) approach and design work tools that can be applied to improve work posture. The results of data processing and analysis obtained a Rapid Entire Body Assessment score on a sandpaper machine single head of 5 and a Rapid Upper Limb Assessment score of 4, the score indicates that the work position has the potential to experience a risk of low back pain, so there must be an improvement in work posture. Work posture improvement is done by designing a tool in the form of a sandpaper machine that takes into account ergonomic dimensions to reduce the risk of lower back injury. The final result after the improvement is obtained Rapid Entire Body Assessment score of 3 and Rapid Upper Limb Assessment score of 4. This shows that the risk of lower back injuries can be minimized.
金属铸造行业,Nitikan是一个微型企业,其生产过程是手工进行的。使用的设备简单,不考虑使用者的健康。这可以从使用砂光机的产品精加工过程中看出。该设备不是根据使用者的姿势设计的,所以操作人员在做工作动作时是弯曲的,当然这是非常危险的,会造成腰痛。本研究旨在利用快速全身评估(REBA)和快速上肢评估(RULA)方法分析整理过程中的工作活动,并设计可用于改善工作姿势的工作工具。数据处理分析的结果得出砂纸机单头快速全身评估得分为5分,上肢快速评估得分为4分,该得分表明该工作姿势有可能经历下腰痛的风险,因此必须在工作姿势上有所改善。工作姿势的改善是通过设计一种工具,以砂纸机的形式,考虑到人体工程学的尺寸,以减少腰背部受伤的风险。改善后的最终结果为快速全身评分3分,快速上肢评分4分。这表明,下背部受伤的风险可以被最小化。

The Artificial Insemination (AI) aims to develop the potential of the cattle reproduction comprehensively. The success of AI results is highly dependent on the level of livestock fertility. Therefore, improv the quality and quantity of semen could be done by hormone induction. However, hormone prices are expensive. This problem could be overcome using alternative way with the natural compound containing chrysin which might has the same function. The purpose of the study was analyze the potential of chrysin compound from Bungli plant ( Oroxylum indicum ) as fertilizer of males through bioinformatics approach. Methods performed through data search by webserver with the following stages: (1) Pubchem, (2) Swiss (3) Target Prediction, (4) Uniprot, (5) Protein Data Bank and (6) docking software using PyRx, PyMOL and Discovery Studio. The results showed that the chrysin compound interact with carbonic anhydrase (CA) expressed from the testes of the cattle, through van der Waals and Pi-Alkyl bonds. Chrysin is effective as CA ligand inducers based on affinity bonds (-8.4 kcal/mole) and more negatively than flavonol as a control compound with binding affinity (-6.2 kcal/mol). This suggests that chrysin is an effective compound as a potential drug for improved livestock fertility.
