Over the years, there have been many advances made within the treatment and diagnosis of Mycobacterium Tuberculosis (Mtb). In recent times, the rise of drug resistance has led to higher mortality rates specifically in poorer countries. There is an urgent need for novel treatment regimens to work against Mtb. A gene family, found in Mtb, PE_PGRS proteins shows potential as a drug target in its life cycle; to prevent the activation of latent Mtb to active Mtb. In silico functional annotations of these proteins are cost-effective and avoid wasting effort on a protein with no potential. Previous studies indicated that the PE_PGRS showed potential for further research. The protein biomarkers which showed the most promise was identified as PE_PGRS17, PE_PGRS31, PE_PGRS50 and PEPGRS54. The sequences of these proteins were searched on the Mycobrowser software. Results were designed by entering these sequences into various computational algorithms. PE_PGRS17 showed characteristics of a potential vaccine candidate. Considering this result, expression profiling and purification was conducted on the recombinant PE_PGRS17 Mtb protein biomarker. The results were calculated using various online software algorithms. Many characterizations and other aspects were predicted to understand the stability, localization, and function of these proteins. All the proteins are estimated to produce an immune response or be involved in the process of immunity. The expression condition of the recombinant PE_PGRS17 was optimised, and purification strategy achieved using E.coli as a host cell. These findings make these proteins, specifically PE_PGRS17, popular for further scientific study. The predicted structures, protein-protein interaction and antigenic properties of the proteins estimate whether the protein can be used for further studies specifically as drug/vaccine targets. Ultimately PE_PGRS17 is seen as the most stable according to its structure and it holds more promise as a key factor to tuberculosis studies.
多年来,在治疗和诊断结核分枝杆菌(Mtb)方面取得了许多进展。近年来,耐药性的上升导致死亡率上升,特别是在较贫穷的国家。迫切需要新的治疗方案来对抗结核分枝杆菌。在结核分枝杆菌PE_PGRS蛋白中发现的一个基因家族在其生命周期中显示出作为药物靶点的潜力;防止潜伏结核分枝杆菌活化为活性结核分枝杆菌这些蛋白质的硅功能注释具有成本效益,避免了在没有潜力的蛋白质上浪费精力。以往的研究表明,PE_PGRS具有进一步研究的潜力。PE_PGRS17、PE_PGRS31、PE_PGRS50和PEPGRS54是最有希望的蛋白生物标志物。在Mycobrowser软件上检索这些蛋白的序列。通过将这些序列输入各种计算算法来设计结果。PE_PGRS17具有潜在候选疫苗的特性。考虑到这一结果,我们对重组PE_PGRS17 Mtb蛋白生物标志物进行了表达谱分析和纯化。使用各种在线软件算法计算结果。许多表征和其他方面的预测,以了解这些蛋白质的稳定性,定位和功能。据估计,所有的蛋白质都能产生免疫反应或参与免疫过程。优化了重组PE_PGRS17的表达条件,确定了以大肠杆菌为宿主细胞的纯化策略。这些发现使得这些蛋白,特别是PE_PGRS17,受到进一步科学研究的欢迎。蛋白质的预测结构、蛋白-蛋白相互作用和抗原特性可评估蛋白质是否可作为药物/疫苗靶点用于进一步研究。最终,根据其结构,PE_PGRS17被认为是最稳定的,它更有希望成为结核病研究的关键因素。

The novel coronavirus disease (COVID-19) has entered a threatening stage all over the world. Many lives have been lost, and many more are in need of treatment. The mild symptoms may include fever and dry cough, but in severe cases, it could lead to pneumonia and ultimately death in some instances. Though medical scientists all over the globe are working hard to develop a treatment for this disease, yet no definite cure has been found. To date, the treatment strategy is based on adopting strategies to break the transmission of the virus and repurposing of the old drugs to prevent the loss of life. Among the various potent candidates, flavonoids may play a protective role in these times. Studies have already proven various health-promoting properties of flavonoids in earlier viral diseases, like SARS and MERS. Since ancient times, been plants have used to treat a number of human diseases. Different phytoproducts have been previously described to inhibit the replication of numerous viruses. Despite the positive reports for plant-based medications, no successful clinical trials on phytoproducts as anti-COVID agents have been conducted to date. This review highlights the efficacy of flavonoids as a treatment strategy either alone or in combination with other drugs.
新型冠状病毒病(COVID-19)在全球范围内已进入威胁阶段。许多人失去了生命,还有更多的人需要治疗。轻微的症状可能包括发烧和干咳,但在严重的情况下,它可能导致肺炎,在某些情况下最终导致死亡。虽然全世界的医学科学家都在努力研究治疗这种疾病的方法,但还没有找到确切的治愈方法。迄今为止,治疗战略的基础是采取阻断病毒传播和重新利用旧药物以防止生命损失的战略。在各种有效的候选物质中,类黄酮可能在这些时候起保护作用。研究已经证明,黄酮类化合物在早期病毒性疾病(如SARS和MERS)中具有多种促进健康的特性。自古以来,植物就被用来治疗许多人类疾病。不同的植物产品先前已被描述为抑制许多病毒的复制。尽管基于植物的药物有积极的报道,但迄今为止还没有成功的植物产品作为抗covid药物的临床试验。这篇综述强调了黄酮类化合物作为单独或与其他药物联合治疗策略的有效性。

New reports offer evidence that under different circumstances, intrauterine mother-infant transmission of SARS-CoV-2 occurs. In contrast, early observations in the COVID-19 pandemic recommended that vertical transmission from women infected with SARS-CoV-2 can be challenging and no virus is detected in human amniotic fluid (HAF). The present study aimed to propose the idea that HAF can be used as a potential therapy for hospitalized, symptomatic, and laboratory-verified SARS-CoV-2 patients by mitigating COVID-19 related inflammation and decreasing its fibrosis. Considering that COVID-19 can cause a severe pulmonary fibrotic response in some patients, HAF by decreasing fibrosis may be considered as an alternative and novel therapy against COVID-19. Lastly, given the inexpensive, easy to access, and safe nature of HAF, integrating this therapy may decrease the COVID-19 attributed death and burden to the health system, especially in countries with limited access to vaccines where HAF is widely available.
新报告提供的证据表明,在不同情况下,会发生SARS-CoV-2的母婴宫内传播。相比之下,COVID-19大流行的早期观察结果表明,感染SARS-CoV-2的女性的垂直传播可能具有挑战性,并且在人羊水(HAF)中未检测到病毒。本研究旨在提出这样一种观点,即HAF可以通过减轻COVID-19相关炎症和减少其纤维化,作为住院、有症状和实验室验证的SARS-CoV-2患者的潜在治疗方法。考虑到COVID-19可在部分患者中引起严重的肺纤维化反应,通过减少纤维化的HAF可被视为对抗COVID-19的替代和新型治疗方法。最后,鉴于HAF的价格低廉、易于获得和安全性,将这种疗法结合起来可能会减少COVID-19导致的死亡和卫生系统的负担,特别是在疫苗获取有限、HAF可广泛获得的国家。

Water is a basic need for the functioning of all life forms that exist on earth. However, current water resources are being polluted by anthropogenic sources, which include social unit, as well as agricultural and industrial waste. People all over the world have concerns about the impact of effluent pollution on the atmosphere, which is increasing day by day. It is hard to purify wastewater before it flows into water reservoirs. Hence, the treatment of wastewater remains an essential need before it is allowed to enter natural water streams. Wastewater treatment is relatively a modern practice. This review will particularly discuss the ways of heavy metal ion removal from wastewater. The ultimate purpose of wastewater management is to improve the health of human and environmental aspects.
水是地球上所有生命形式运作的基本需要。然而,目前的水资源正受到人为污染源的污染,其中包括社会单位以及农业和工业废物。全世界的人们都在关注污水污染对大气的影响,这是日益增加的。在废水流入水库之前进行净化是很困难的。因此,在废水进入自然水流之前,对其进行处理仍然是必不可少的。废水处理是一种相对现代化的做法。本文重点讨论了废水中重金属离子的去除方法。废水管理的最终目的是改善人类健康和环境方面。

In today's global world, most women are experiencing midlife health problems which can affect their lives and mental status. Most of the diseases occurr after childbirth and during pregnancy or gestation period which can lead to severe problems such as postpartum depression (PPD), postmenopausal depression, perimenopausal depression which ultimately affects the mental health condition and develop various depressive episodes which ultimately lead to depression in women. The review paper gives the information that if there is untreated maternal depression then it can lead to anxiety, fear, negative effect on child development, disruption of the mother-infant relationship, and the occurrence of depressive symptoms in the early life of infants. Hormone levels are changed at the time of pregnancy. The data was collected by studying combination of research and review papers from different databases like PubMed, Medline, and Web of science by using search keywords like “Postpartum depression”, “Postmenopausal depression”, “Risk factors”, “Pathogenesis of PPD”, “Predictors of postpartum depression”. This can lead to disrupting the quality of life of menopausal women like deficiency of nutrients, not properly regular physical activities, elevated Body Mass Index (BMI), loss of libido (loss of interest in sexual activities), due to the lack of education, and awareness among the people. Factors like increase in physical activity can naturally help in PPD condition. Mind body therapy, drug therapy and cognitive and mindfulness-based therapies help in hormonal imbalances. It was found that low birth weight and congenital abnormalities in babies lead to affect depression after delivery. It is recommended that health care providers and physicians are provided with information regarding factors contributing PPD and postmenopausal depression. Sleep timings and consumptions of nutraceuticals can help in natural healing with depression amongst women suffering from postpartum, postmenopausal and perimenopausal depression.
在当今全球化的世界中,大多数妇女正在经历中年健康问题,这些问题会影响她们的生活和精神状态。大多数疾病发生在分娩后和怀孕或妊娠期间,可导致严重的问题,如产后抑郁症(PPD),绝经后抑郁症,围绝经期抑郁症,最终影响精神健康状况,并发展各种抑郁发作,最终导致妇女抑郁。这篇综述文章给出的信息是,如果母亲抑郁症得不到治疗,那么它可能导致焦虑、恐惧,对儿童发育产生负面影响,破坏母婴关系,并在婴儿的早期生活中出现抑郁症状。在怀孕期间,激素水平会发生变化。通过检索关键词“产后抑郁”、“绝经后抑郁”、“危险因素”、“PPD发病机制”、“产后抑郁的预测因素”等,结合PubMed、Medline、Web of science等不同数据库的研究与综述论文收集数据。由于缺乏教育和意识,这会导致更年期妇女的生活质量受到破坏,如营养缺乏,没有适当的规律体育活动,身体质量指数(BMI)升高,性欲丧失(对性活动失去兴趣)。增加体力活动等因素自然有助于治疗产后抑郁症。身心疗法、药物疗法以及认知和正念疗法有助于缓解荷尔蒙失衡。研究发现,低出生体重和婴儿先天畸形会影响产后抑郁。建议向卫生保健提供者和医生提供有关PPD和绝经后抑郁因素的信息。睡眠时间和营养保健品的消费可以帮助自然愈合抑郁症的妇女遭受产后,绝经后和围绝经期抑郁症。

Most of the diseases occurr after childbirth and during pregnancy or gestation period which can lead to severe problems such as postpartum depression (PPD), postmenopausal depression, perimenopausal depression which ultimately affects the mental health condition and develop various depressive episodes which ultimately lead to depression in women. The review paper gives the information that if there is untreated maternal depression then it can lead to anxiety, fear, negative effect on child development, disruption of the mother-infant relationship, and the occurrence of depressive symptoms in the early life of infants. Hormone levels are changed at the time of pregnancy. The data was collected by studying combination of research and review papers from different databases like PubMed, Medline, and Web of science by using search keywords like “Postpartum depression”, “Postmenopausal depression”, “Risk factors”, “Pathogenesis of PPD”, “Predictors of postpartum depression”. This can lead to disrupting the quality of life of menopausal women like deficiency of nutrients, not properly regular physical activities, elevated Body Mass Index (BMI), loss of libido (loss of interest in sexual activities), due to the lack of education, and awareness among the people. Factors like increase in physical activity can naturally help in PPD condition. Mind body therapy, drug therapy and cognitive and mindfulness-based therapies help in hormonal imbalances. It was found that low birth weight and congenital abnormalities in babies lead to affect depression after delivery. It is recommended that health care providers and physicians are provided with information regarding factors contributing PPD and postmenopausal depression. Sleep timings and consumptions of nutraceuticals can help in natural healing with depression amongst women suffering from postpartum, postmenopausal and perimenopausal depression.","PeriodicalId":22949,"journal":{"name":"The Open Biology Journal","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79921019","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}

Natural herbs such as neem, hibiscus, henna leaves, amla fruit and reetha epicarp are the components of the natural herbal shampoos used in this study. Soxhlet apparatus was used for water-based extraction of these natural herbs, whereas the maceration process was used for alcohol-based extraction. Nine formulations were prepared and evaluated by using different parameters like physical appearance, viscosity, surface tension, foam volume, pH, solid content, dirt dispersion and wetting time.
天然草药,如楝树,木槿,指甲花叶,amla果实和reetha外皮是本研究中使用的天然草药洗发水的成分。采用索氏装置对天然草药进行水基提取,采用浸渍法对天然草药进行醇基提取。通过物理外观、粘度、表面张力、泡沫体积、pH、固含量、污垢分散和润湿时间等参数对9种配方进行了评价。
