Growing nanostructures by green synthesis is an attractive method with a lot of applications, such as antibacterial, anticancer, antifungal and water treatment, etc. Copper oxide nanoparticles have been fabricated using the extract of Aloe Barbandanum, famous with the name of Aloe vera. These nanoparticles are important due to their applications in medical sciences. Structural, optical, compositional, and morphological properties of synthesized nanoparticles were studied and reported here. The phases and crystallite size were determined using X-ray Diffraction and the UV-visb was used to find out the direct bandgap and the absorbance near the visible range. Fourier Transform Infrared Spectroscopy spectra confirmed the presence of a strong band of metal oxide near 606 cm-1. Using Scanning Electron Microscope the average grain size was obtained as small as 60 nm. These fabricated CuO NPs were tested for their possible uses against the MCF-7 cell line (breast cancer cells) and results are presented.

Aloe vera is part and parcel of the Liliaceae family. This is one of 250 Aloe Barbadensis species, scientifically known as Aloe Vera. Acemannane, one of the most bioactive polysaccharides of Aloe Vera, has effects of immunity modulation, anti-cancer, anti-oxidation, bone repair, neuroprotection and promotion of intestinal health. The mucilaginous gel in the pulp of aloe vera formed by the parenchymal cells has been used for a variety of curative applications since ancient times. Aloe vera is a nutraceutical product used mostly for decades. It is available in a range of health drinks and wellness beverages, in capsules/tablets and in gels & creams externally. This article includes the bioactive components, extraction and processing of aloe vera and the prospects of tissue engineering. This article highlights important uses as a nutraceutical, medicinal, and therapeutic food potential of A. vera constituents. Aloe vera nutraceutical gel scaffolds, such as acemannan, promote biomedical biomedical and polymeric tissue management. The presence of over 200 phytochemicals was revealed by Aloe vera gel. Aloe vera gel from its leaves is extracted and the stabilisation and preparation of the final products requires adequate processing techniques.

  Weeds are the undesirable and unwanted plants in the wrong place in a situation that can significantly decrease the yield of desirable plant such as sugarcane. One solution to tackle this problem is the development of herbicide resistant crops like sugar cane that are highly resistant to several herbicides or broad-spectrum herbicides which is done in most cases by genetic transformation, site-directed mutagenesis, and plant breeding. Sugarcane (Saccharum officinarum) is the 2nd vital cash crop of Pakistan, placed at 6th position in world cane acreage and 15th in sugar production. Hence, sugarcane occupies a crucial position in the economy of Pakistan and acts like a backbone in economic development of country. There are several reasons for the lower sugarcane yield in Pakistan but the most important is the large number of weeds that covered most of the area of sugarcane cultivated fields which results in major loss of sugarcane yield in terms of quality and quantity. Broad spectrum herbicide resistant plants are produced to tackle this issue by the insertion of CP4 EPSPS (Glyphosate tolerant gene; 5-enolpyruvulshikimate-3-phosphate synthase from Agrobacterium tumefaciens strain CP4) into sugarcane which provides them the ability to survive after the spray of glyphosate but weeds do not survive in this condition. The most common herbicide resistant technology is Glyphosate resistant technology which gives broad-spectrum weed control feasibility along with the flexibility in the application time of herbicide. There are numerous methods of transformation which are available now-a-days for insertion of foreign DNA into plant cells like Agrobacterium-mediated transformation, micro-projectile bombardment (gene gun) and protoplast transformation. Glyphosate tolerant gene expression is showed by three sugarcane cultivars (CPF-213, SPF-234 and HSF-240). Transgenic sugarcane plants showed these expressions are most stable against herbicide to control weeds. Several farmers in many countries have rapidly and extensively utilized herbicide-tolerant crops due to low production and labour costs, huge profit, increased weed control and many environmental benefits.
杂草是在错误的地方出现的不受欢迎和不受欢迎的植物,在这种情况下会显著降低甘蔗等理想植物的产量。解决这一问题的一个办法是开发抗除草剂作物,如甘蔗,这种作物对几种除草剂或广谱除草剂具有高度抗性,这在大多数情况下是通过基因转化、定点诱变和植物育种来实现的。甘蔗(Saccharum officinarum)是巴基斯坦第二大重要经济作物,在世界甘蔗种植面积中排名第6,在糖产量中排名第15。因此,甘蔗在巴基斯坦经济中占有至关重要的地位,是国家经济发展的支柱。巴基斯坦甘蔗产量下降有几个原因,但最重要的原因是大量杂草覆盖了大部分甘蔗种植面积,导致甘蔗产量在质量和数量方面遭受重大损失。通过插入CP4 - EPSPS(草甘膦耐受基因),生产出广谱抗除草剂植物来解决这一问题;从农杆菌菌株CP4中提取的5-烯醇丙酮草酸-3-磷酸合成酶转化为甘蔗,使它们能够在喷洒草甘膦后存活,而杂草在这种条件下无法存活。最常见的抗除草剂技术是抗草甘膦技术,它具有广谱控制杂草的可行性和除草剂施用时间的灵活性。目前有许多将外源DNA插入植物细胞的转化方法,如农杆菌介导的转化、微弹轰击(基因枪)和原生质体转化。3个甘蔗品种CPF-213、SPF-234和HSF-240均有耐草甘膦基因的表达。结果表明,这些基因表达在甘蔗转基因植株中对除草剂控制杂草最稳定。由于生产成本低、劳动力成本高、利润丰厚、杂草防治效果好、环境效益好,许多国家的一些农民迅速和广泛地使用了耐除草剂作物。

Use of microbial consortium along with biosurfactants in oil sludge treatment 微生物联合生物表面活性剂在油泥处理中的应用
Pub Date : 2021-08-17 DOI: 10.53992/njns.v5i2.48
Tahreem Zaheen, Shumyila Nasir, G. Naz
Due to the excessive use of various oils, a large amount of oil sludge or waste water is produced annually which is causing various environmental and health issues. Bioremediation through the use of microbial consortium is an effective method. The use of consortium instead of single specie of bacteria has shown 89-94% improved results. However the microbes are still not able to work effectively due to bioavailability issues. This is mainly because of the low solubility of hydrophobic contaminants and microbes. This problem is overcome by use of biosurfactants which enhance the solubility and emulsification of hydrophobic substrates and microbes. These biosurfactants are produced by various organisms (mainly microbes) which are later isolated and used. Certain new and efficient insitu techniques are used for the application of microbial consortium which includes suspended growth, attached growth and hybrid growth. Waste water treated this way can be reused in the refinery procedures or can be dumped safely.
由于各种油的过度使用,每年产生大量的油泥或废水,造成各种环境和健康问题。利用微生物联合体进行生物修复是一种有效的方法。使用联合体代替单一菌种的效果提高了89-94%。然而,由于生物利用度问题,微生物仍然无法有效地发挥作用。这主要是因为疏水污染物和微生物的溶解度低。这个问题是克服使用生物表面活性剂,提高溶解度和乳化疏水底物和微生物。这些生物表面活性剂是由各种生物(主要是微生物)产生的,这些生物后来被分离出来并使用。一些新的高效的原位技术被用于微生物群落的应用,包括悬浮生长、附着生长和杂交生长。用这种方法处理的废水可以在炼化过程中重复使用,也可以安全地倾倒。

Anemia is a pathological condition characterized by a reduction in the mass of red blood cells or the amount of hemoglobin. Anemia affects one-third of the world's population, with iron deficiency accounting for half of the cases. It's a major global public health problem that has an effect on maternal and child mortality, physical fitness, and referral to health-care providers. Underweight children have a greater prevalence of anemia, which can produce long-term developmental outcomes. Particular risk is presented by children 0-5 years, child-bearing mothers and pregnant women. Efforts to avoid anemia should concentrate on improving current supplementary iron and folate programs and on preventing folate and vitamin B12 anemia deficiency. In this review biological mechanism and condition of anemia development has been discussed. A further study is necessary to examine the function of additional nutrient deficits, the contribution of infectious and chronic illnesses in some populations, and the significance of hereditary hemoglobin disorders.
贫血是一种以红细胞或血红蛋白数量减少为特征的病理状态。贫血影响着世界上三分之一的人口,其中缺铁占一半。这是一个重大的全球公共卫生问题,对孕产妇和儿童死亡率、身体健康以及向卫生保健提供者转诊产生影响。体重过轻的儿童更容易患贫血,这可能会对发育产生长期影响。0-5岁儿童、育龄母亲和孕妇面临的风险尤其大。避免贫血的努力应该集中在改善目前的补充铁和叶酸计划以及预防叶酸和维生素B12缺乏症上。本文就贫血发生的生物学机制和条件进行了讨论。有必要进一步研究额外营养缺乏的作用、传染性和慢性疾病在某些人群中的作用以及遗传性血红蛋白疾病的意义。

Cardiac hypertrophy is the major pathway by which neurohormonal and mechanical stimuli act upon cardiomyocytes which gives the response to these stimuli. It leads to heart failure and ventricular dilation which is the main root of mortality in the western world. Many molecular targets are controlling cardiac hypertrophy development which may influence the growth factors signaling, cytokine release and gene expression. Through clinical trials on different models, recent research shows that cardiac hypertrophy might be inhibited or reversed. These findings have developed a vast drive to recognize specific and novel regulators of cardiac hypertrophy. Many molecular targets and signaling modulators have been studied in this review that induce the hypertrophic response which may involve MAPK pathway, oxidative stress, calcineurin, Cardiac angiogenesis, serum protein concentration, microRNA, and periodontitis. For the treatment of cardiac hypertrophy, the scientific knowledge of these signaling pathways and factors may be translated into potential nutritional and molecular therapies for the betterment of this diseases. The current and previous knowledge of molecular markers can be compiled in this review for the treatment of the molecular pathogenesis of cardiac hypertrophy.
心肌肥大是神经激素和机械刺激作用于心肌细胞的主要途径,心肌细胞对这些刺激作出反应。它会导致心力衰竭和心室扩张,这是西方世界死亡率的主要根源。许多分子靶点控制着心肌肥厚的发生,从而影响生长因子信号、细胞因子释放和基因表达。通过不同模型的临床试验,最近的研究表明心脏肥厚可能被抑制或逆转。这些发现已经开发了一个巨大的驱动器,以识别特定的和新的调节心脏肥厚。本文综述了许多诱导增生性反应的分子靶点和信号调节剂,包括MAPK通路、氧化应激、钙调神经磷酸酶、心脏血管生成、血清蛋白浓度、microRNA和牙周炎。对于心脏肥厚的治疗,这些信号通路和因子的科学知识可能转化为潜在的营养和分子治疗,以改善这种疾病。本文综述了分子标志物的现有和既往知识,为心肌肥厚的分子发病机制的治疗提供参考。

Computational Screening of Phytochemicals against Munc13-1, a Promising target to treat Alcoholism 抗Munc13-1植物化学物质的计算筛选——一个治疗酒精中毒的有希望的靶点
Pub Date : 2021-01-01 DOI: 10.53992/njns.v5i2.50

In silico analysis and characterization has revolutionized target and drug discovery significantly. Alcohol abuse is a big threat to society, economy and wellbeing of people. It has increased the overall disease and injury burden, globally. Recently, a study revealed a brain protein, Munc13-1 C1 domain to play a significant role in development of alcohol tolerance, by binding to alcohol molecules, eventually leading to Alcohol Use Disorder. The aim of this study was to discover a phytochemical that would attach to our target protein, Munc13-1 C1 domain so that it cannot bind with the alcohol molecules. Munc13-1 3D structure obtained from PDB was docked against a library of compounds by MOE software. Ten phytochemicals based on their binding affinity with the target protein were shortlisted i.e. Tannic Acid, Anemone blue anthocyanin 1, Oolonghomobisflavan B, Diosmin, Oolonghomobisflavan A, Neodiosmin, Blepharocalyxin B, 8-Hydroxyhesperetin, Eupatorin and Monotesone A. However, only 8-Hydroxyhesperetin, Eupatorin and Monotesone A followed Lipinski rules. They were non-toxic and non-carcinogenic according to SwissADME. Moreover, have a good drug-like model score as analysed by Molsoft. Further, in-vivo and invitro examinations are required to inspect their role in reducing alcohol tolerance.
在硅分析和表征革命性的目标和药物发现显著。酗酒是对社会、经济和人民福祉的一大威胁。它增加了全球的总体疾病和伤害负担。最近,一项研究揭示了一种名为Munc13-1 C1结构域的大脑蛋白,通过与酒精分子结合,最终导致酒精使用障碍,在酒精耐受性的发展中发挥重要作用。这项研究的目的是发现一种植物化学物质,可以附着在我们的目标蛋白Munc13-1 C1结构域上,使其不能与酒精分子结合。通过MOE软件将从PDB中获得的Munc13-1三维结构与化合物库对接。根据与目标蛋白的结合亲和性,筛选出了鞣酸、海葵蓝花青素1、乌龙同质黄烷B、薯蓣皂苷、乌龙同质黄烷A、新薯蓣皂苷、Blepharocalyxin B、8-羟基橙皮苷、Eupatorin和montesone A等10种植物化学物质,但只有8-羟基橙皮苷、Eupatorin和montesone A符合Lipinski规则。根据SwissADME,它们是无毒和无致癌的。此外,根据Molsoft分析,具有良好的药物样模型评分。此外,还需要进行体内和体外试验来检验它们在降低酒精耐受性方面的作用。

Further, in-vivo and invitro examinations are required to inspect their role in reducing alcohol tolerance.","PeriodicalId":19373,"journal":{"name":"NUST Journal of Natural Sciences","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73690809","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}

Viral Hepatitis is the seventh leading cause of death worldwide and prevails in many developing countries specifically in the Middle East and North African regions. The current study focuses on a comparatively low-income province of Pakistan, Khyber Pakhtunkhwa where medical facilities are scarce and the use of blood and its products, free from viral hepatitis and other pathogens, is poorly ensured. The preliminary phase of the study involved a systematic literature review on the epidemiology of Hepatitis C Virus in KP during the period 2000-2018 through PubMed, Science Direct, and Google Scholar. After statistical coding, an initial meta-analysis was conducted to come up with an integrated estimate of the prevalence of Hepatitis C Virus in Khyber Pakhtunkhwa. The prevalence rate of 4% by fixed effect model and of 6% by random effect model is extremely alarming, especially in a low-income region, and the Pakistani government should adopt effective and rapid strategies to eliminate Hepatitis C Virus infection by the end of 2030, as more times announced by the World Health Organization.
病毒性肝炎是全世界第七大死因,在许多发展中国家,特别是中东和北非地区普遍存在。目前的研究重点是巴基斯坦一个相对低收入的省份,开伯尔-普赫图赫瓦省,那里的医疗设施很少,血液及其制品的使用没有病毒性肝炎和其他病原体,保障很差。该研究的初步阶段包括通过PubMed、Science Direct和Google Scholar对2000-2018年期间KP丙型肝炎病毒流行病学进行系统的文献综述。在进行统计编码后,进行了初步的meta分析,以得出开伯尔-普赫图赫瓦省丙型肝炎病毒流行率的综合估计。固定效应模型4%的流行率和随机效应模型6%的流行率是非常惊人的,特别是在低收入地区,巴基斯坦政府应该采取有效和快速的战略,到2030年底消除丙型肝炎病毒感染,正如世界卫生组织多次宣布的那样。
