The nanotechnology sector is regarded as a developing technology due to its capacity to improve the already existing items and create new ones for a range of uses. The primary drivers of this expansion are cyclodextrin-based porous nanoparticles or distinctive nanosponges, which have lately been applied in the pharmaceutical, biomedical, and cosmetic industries. This superior technology can circumvent the defects of current techniques through its ability to attack and visualize tumor sites. The organization of this review article is such that we first looked at the distinctive characteristics of these nanosponges and the various synthesizing techniques, then about the drug loading and release principle and applications based on drug delivery, targeting, increasing the solubility of BCS Class II and IV drugs, other applications in biomedicine, and more. The most recent developments on the employment of biomimetic nanosponge as a pandemic tool because of the SARS-CoV-2 virus briefly align. Due to several significant limitations, effective targeted drug delivery systems have long been an aspiration. These issues might be resolved by the creation of new colloidal carriers termed Nanosponges.
纳米技术部门被认为是一种发展中的技术,因为它有能力改进现有的项目并为一系列用途创造新的项目。这种扩张的主要驱动力是基于环糊精的多孔纳米颗粒或独特的纳米海绵,它们最近被应用于制药、生物医学和化妆品行业。这种优越的技术可以通过其攻击和可视化肿瘤部位的能力来规避当前技术的缺陷。本文的组织结构是这样的,我们首先研究了这些纳米海绵的独特特性和各种合成技术,然后介绍了基于药物传递,靶向,增加BCS II类和IV类药物的溶解度的药物装载和释放原理及其在生物医学中的应用等。由于SARS-CoV-2病毒,使用仿生纳米海绵作为大流行工具的最新进展短暂一致。由于一些显著的限制,有效的靶向药物递送系统一直是人们的愿望。这些问题可以通过创造新的胶体载体来解决,这种胶体载体被称为纳米海绵。

Cassia fistula L., also known as ‘Golden shower tree’ or ‘Indian laburnum’ of the Fabaceae family, is a common ornamental tree with various medicinal uses. It is a medium or large-sized deciduous tree found in Asian countries, especially in India, Myanmar, Sri Lanka, Thailand, etc. This species has cultural importance as it is the national tree of Thailand and the flower is considered as the state flower of Kerala. Various medicinal activities are identified on basis of traditional knowledge. This research article enlightens the physicochemical characters, comparative successive solvent extraction, and qualitative phytochemical screening of various extracts of Cassia fistula L. roots. The present study aims to compare successive solvent extraction (maceration and soxhlation) for the estimation of yield and qualitative phytochemical screening of extracts obtained through both extractions. Two methods of successive solvent extraction were done, i.e., maceration and soxhlation using solvents of increasing polarity such as petroleum ether, chloroform, ethyl acetate, methanol, and distilled water. The phytochemical tests were carried out for each extract using standard methods of analysis and these investigations. The yields of extract were calculated as %w/w in all five solvents. Comparison of extraction methods helps to determine which method gives the maximum yield of extraction and preliminary phytochemical studies help to find out the secondary metabolites present in the extracts from both methods and compare the results.
决明,也被称为“金色淋浴树”或“印度金花”的豆科植物,是一种常见的观赏树木,具有多种药用价值。它是一种中型或大型落叶乔木,分布在亚洲国家,特别是在印度,缅甸,斯里兰卡,泰国等。这个物种具有文化重要性,因为它是泰国的国树,这种花被认为是喀拉拉邦的国花。在传统知识的基础上确定了各种药物活动。本研究对决明子根不同提取物的理化性质、比较连续溶剂提取、定性植物化学筛选等方面进行了阐述。本研究的目的是比较连续的溶剂提取(浸渍和曝晒),以估计产量和定性植物化学筛选通过两种提取获得的提取物。用石油醚、氯仿、乙酸乙酯、甲醇和蒸馏水等极性递增的溶剂,进行了浸渍和草酸两种连续溶剂萃取。采用标准的分析方法和这些调查方法对每种提取物进行了植物化学试验。在所有五种溶剂中,提取液的得率以%w/w计算。比较提取方法有助于确定哪一种方法的提取率最高,初步的植物化学研究有助于找出两种方法提取物中存在的次生代谢物,并比较结果。

According to the Centers for Disease Control and Prevention (CDC), the transmission of SARS-COV-II occurs mostly person-to-person via respiratory droplets within a range of 180 cm. The virus can also be transmitted if a person touches a mucosal surface after touching an object with the virus on it.14 Human-to-human transmission of the Severe acute respiratory syndrome coronavirus 2 (SARS-COV-II) occurs most often when people are in the incubation stage of the disease or are carriers and have no symptoms. [...]the role of environmental factors and conditions such as temperature, humidity, wind speed as well as food, water and sewage, air, insects, inanimate surfaces, and hands in COVID-19 transmission. [...]SARS-COV-II transmission through food, food packages, and food handlers has not been identified as a risk factor for the disease.15 Transmission may also occur through fomites in the immediate environment around the infected person. [...]the transmission of the COVID-19 virus can occur by direct contact with infected people and indirect contact with surfaces in the immediate environment or with objects used on the infected person like a stethoscope or thermometer.16 Consumption of alcohol will not kill the virus in the inhaled air;it will not disinfect your mouth and throat, and it will not give you any kind of protection against COVID-19.17 1.2 Introduction of Disinfectant and Sanitizer: Germ-killing products are used in foodservice and health care. Disinfectants kill 100% of certain microorganisms, but they are not used on people, only inanimate surfaces. Because disinfectants do not kill all microorganisms, especially bacterial spores, they are different from sterilants.18 1.2.2 Sanitizer: An agent that reduces the number of disease-causing (pathogenic) bacteria on an inanimate food contact surface to safe levels as judged by public health requirements.
根据美国疾病控制与预防中心(CDC)的说法,SARS-COV-II的传播主要是在180厘米范围内通过呼吸道飞沫进行人际传播。如果一个人在接触带有病毒的物体后接触粘膜表面,病毒也会传播严重急性呼吸综合征冠状病毒2 (SARS-COV-II)的人际传播最常发生在人们处于该疾病的潜伏期或携带者且没有症状时。[…温度、湿度、风速以及食物、水和污水、空气、昆虫、无生命表面和手等环境因素和条件在COVID-19传播中的作用。[…SARS-COV-II通过食品、食品包装和食品处理人员传播尚未被确定为该疾病的危险因素也可通过感染者周围环境中的污染物传播。[…[16] COVID-19病毒的传播可通过直接接触感染者和间接接触直接环境中的表面或听诊器或温度计等感染者使用的物体发生饮用酒精不会杀死吸入空气中的病毒,也不会对口腔和喉咙进行消毒,也不会为您提供任何预防covid - 17的保护。1.2消毒剂和消毒剂的介绍:杀菌产品用于食品服务和医疗保健。消毒剂能100%杀灭某些微生物,但它们不能用于人体,只能用于无生命的表面。因为消毒剂不能杀死所有的微生物,尤其是细菌孢子,所以它与消毒剂不同。1.2.2消毒剂:根据公共卫生要求,将无生命的食品接触表面上的致病(致病菌)细菌数量减少到安全水平的药剂。

Hypertension is a turning into a significant danger to the world. In the hunt of lead atoms from plant beginning as a substitute for poisonous engineered drugs, 26 Indian restorative plants and nourishments were screened for their ACE (Angiotensin Converting Enzyme) inhibitory movement. IC50 (half restraint of ACE) estimations of hydroalcoholic unrefined concentrates and division were dictated by a colorimetric technique. Dynamic parts were additionally screened to decide the compound energy, mode, explicitness and instrument of restraint. Normalization was finished by deciding aggregate phenolics and flavonoids as gallic corrosive and quercetin counterparts/mg of concentrate individually. Among 26 unrefined concentrates, Cynara scolymus extricate indicated the best action, IC50 esteem 356.62µg/mL. Pro restraint coming about because of protein precipitation was most noteworthy in Coscinium fenestratum. Lineweaver-Burk plots uncovered a serious method of restraint for Punica granatum ethyl acetic acid derivation part. Divisions of Cynara scolymus were seen as vague inhibitors of ACE. Coscinium fenestratum parts restrained the ACE by Zn2+ particle chelation. Further, in the quest for sheltered and powerful lead atoms from normal sources, (MP) Mucuna pruriens L. (Fabaceae) seeds were used for investigating the antihypertensive potential. Generally it is utilized as diuretic and Hypotensive. Bioassay-guided divisions were used for the separation of dynamic mixes by segment chromatography. IC50 esteem, protein energy and restraint system were resolved. In vivo time and portion subordinate hypotensive examination followed by changes in the MAP (Mean blood vessel pressure) actuated by angiotensin I (3 nmol/kg), angiotensin II (3nmol/kg), and to bradykinin (10nmol/kg) in anesthetized rodents was finished. Plasma and tissue ACE exercises were additionally decided. Phytochemical examination by spectroscopic methods uncovered the nearness of realized mixes like genistein, ursolic corrosive and L-DOPA from the ethyl acetic acid derivation and water part separately. In vitro examination uncovered MP ethyl acetic acid derivation portion (MPEA) and genistein as the most dynamic part (IC50 156.45µg/mL) and compound (IC50 253.81µM) individually. Lineweaver-Burk plots uncovered a non-serious method of hindrance. Expert protein precipitation was the recommended instrument for restraint. The concentrate indicated a time and portion subordinate decline in the MAP.
高血压正在转变为对世界的重大危险。在寻找铅原子作为有毒工程药物的替代品的过程中,对26种印度恢复性植物和营养物进行了ACE(血管紧张素转换酶)抑制运动的筛选。用比色法测定了未精制氢醇浓缩物的IC50 (ACE的半抑制)和分裂。对动态部件进行了筛选,确定了复合能、约束方式、约束显式和约束手段。通过测定总酚和总黄酮分别为没食子腐蚀物和槲皮素对应物/mg的浓缩物来完成归一化。在26种未精制的浓缩物中,蛇尾草提取物的IC50值为356.62µg/mL,效果最好。蛋白沉淀引起的亲抑制在黄芩中最为显著。Lineweaver-Burk图揭示了石榴乙酯乙酸衍生部分的严重抑制方法。弓形虫的分裂被认为是ACE的模糊抑制剂。孔雀石部分通过Zn2+颗粒螯合抑制ACE。此外,为了从正常来源寻求庇护和强大的铅原子,(MP) Mucuna pruriens L. (Fabaceae)种子被用于研究降压潜力。一般用作利尿剂和降压药。生物测定引导分离采用段色谱法对动态混合物进行分离。IC50自尊、蛋白质能量和约束系统进行了求解。实验完成了在体时间和局部降压检查,并观察了血管紧张素I (3nmol/kg)、血管紧张素II (3nmol/kg)和缓激素(10nmol/kg)对麻醉啮齿动物MAP(平均血管压)的影响。血浆和组织ACE运动也决定。通过光谱学方法进行植物化学检测,发现分别从乙酸乙酯衍生物和水组分中分离出染料木素、熊果酸和左旋多巴等化合物。体外检测发现MP乙酸乙酯衍生物部分(MPEA)和染料木素分别为活性最强的部分(IC50为156.45µg/mL)和化合物(IC50为253.81µM)。织线者-伯克图揭示了一种非严重的阻碍方法。专家蛋白沉淀是推荐的抑制仪器。浓缩物的MAP呈时间和比例递减。

The dental herbs are very much essential for the treatment of many dental problems. They can be used as such or in the form of dental formulations. These dental formulations of the herbs have enormous economical importance too. Apart from the pharmaco-therapeutic role the pharmacognostic and it’s chemical composition is also essential. These parameters help to modify the formulations and to overcome the adverse drug effects associated with these. The present review work tries to highlight the Pharmacognostic and Phytochemical aspects of three dental herbs.

Many evidences suggested that stressful experience might affect diabetes. The estimate of the actual number of diabetes in India is around 40 million. This means India actually has the highest number of diabetic’s patient of any one country in entire world. No doubt, one of the natural element of life i.e. Stress is a major contributor to the diabetes. Stress can bring many unexpected changes in the blood sugar level; this could trigger symptoms associated with diabetes. Some retrospective human studies have suggested that the stress can participate in Type-1 diabetes, animal studies have shown that stress can cause Type-1 diabetes. impaired glucose tolerance and metabolic disease, however human studies have shown that stress can stimulate hyperglycaemia, insulin resistance. In contrast more consistentevidence support the role of stress in Type-2 diabetes. In recent year the complexities of the relationship between stress and diabetes have become well known but have been less well researched. Some studies have suggested that stressful experience may affect the onset and the metabolic control of diabetes, but finding have often been inconclusive. In this article we reviewed some of this research going on to consider how stress might affect the diabetes and physiological mechanism through which this may occurs and their preventions and management.
许多证据表明,压力经历可能会影响糖尿病。据估计,印度糖尿病患者的实际人数约为4000万。这意味着印度实际上是世界上糖尿病患者人数最多的国家。毫无疑问,生活中的自然因素之一,即压力是糖尿病的主要诱因。压力会给血糖水平带来许多意想不到的变化;这可能引发与糖尿病相关的症状。一些回顾性的人体研究表明,压力可以参与1型糖尿病,动物研究表明,压力可以引起1型糖尿病。糖耐量受损和代谢疾病,然而,人类研究表明,压力可以刺激高血糖,胰岛素抵抗。相比之下,更一致的证据支持压力在2型糖尿病中的作用。近年来,压力和糖尿病之间关系的复杂性已经广为人知,但研究却很少。一些研究表明,压力经历可能影响糖尿病的发病和代谢控制,但这一发现往往是不确定的。在这篇文章中,我们回顾了一些正在进行的研究,以考虑压力如何影响糖尿病和可能发生这种情况的生理机制以及它们的预防和管理。

The barrier properties of the topmost layer of the skin, stratum corneum have significant limitations for successful systemic delivery of a wide range of therapeutic molecules, especially macromolecules and genetic material. One solution is to utilize microneedles (MNs), which are capable of painlessly traversing through the stratum corneum and directly translocating protein drugs into the systematic circulation. This strategy involves the use of micron sized needles fabricated from different materials and using different geometries to create transient aqueous conduits across the skin. Microneedles in isolation, or in combination with other enhancing strategies, have been shown to dramatically enhance the skin permeability of numerous therapeutic molecules including biopharmaceuticals either in vitro, ex vivo or in vivo. MNs can be designed to incorporate appropriate structural materials as well as therapeutics or formulations with tailored physicochemical properties. This platform technique has been applied to deliver drugs both locally and systemically in applications ranging from vaccination to diabetes and cancer therap. As an alternative to hypodermic needles, coated polymer microneedles (MNs) are able to deliver drugs to subcutaneous tissues after being inserted into the skin. The dip-coating process is a versatile, rapid fabricating method that can form coated MNs in a short time. However, it is still a challenge to fabricate coated MNs with homogeneous and precise drug doses in the dip-coating process. This review article focuses on recent and potential future developments in microneedle technologies. This will include the detailing of progress made in microneedle design, an exploration of the challenges faced in this field and potential forward strategies to embrace the exploitation of microneedle methodologies, while considering the inherent safety aspects of such therapeutic tools. The clinical potential and future translation of MNs are also discussed.
皮肤最上层角质层的屏障特性对广泛的治疗性分子,特别是大分子和遗传物质的成功全身递送有很大的限制。一种解决方案是利用微针(MNs),它能够无痛地穿过角质层,直接将蛋白质药物转运到全身循环中。这种策略包括使用微米大小的针,由不同的材料制成,并使用不同的几何形状,在皮肤上创建瞬时水导管。微针单独使用,或与其他增强策略结合使用,已被证明在体外、离体或体内显著提高许多治疗性分子的皮肤渗透性,包括生物药物。MNs可以设计成包含适当的结构材料以及具有定制物理化学性质的疗法或配方。这种平台技术已经应用于局部和系统的药物输送,从疫苗接种到糖尿病和癌症治疗。作为皮下注射针头的替代品,涂覆聚合物微针(MNs)在插入皮肤后能够将药物输送到皮下组织。浸涂工艺是一种通用的、快速的制备方法,可以在短时间内形成涂覆的纳米颗粒。然而,在浸渍包膜工艺中,如何制备均匀、精确的药物剂量的包膜纳米粒子仍然是一个挑战。本文综述了微针技术的最新进展和潜在的未来发展。这将包括详细介绍微针设计的进展,探索该领域面临的挑战和潜在的未来战略,以拥抱微针方法的开发,同时考虑到这种治疗工具的固有安全性。本文还讨论了MNs的临床潜力和未来的翻译。
