Nanoparticles are defined as particles with size in the range of 1 to 100 nm at least in one of the three dimensions. Because of this very small size scale, they possess an immense surface area per unit volume, a high proportion of atom in the surface and near surface layers, and the ability to exhibit quantum effect. Nanotechnology represents one of the most capable technologies of the 21 century. Solid lipid nanoparticles introduced in 1991 represent an alternative carrier system to traditional colloidal carriers such as emulsion, liposomes and polymeric micro and nanoparticles Nanotechnology is widely used in various cosmetic and dermatological products like lipsticks, soap, antiwrinkle cream, perfumes, toothpaste etc. Nanoparticles serve as the fundamental building block for various nanotechnology applications. Nanotechnology is one of the most capable techniques which are safe and effective for targeted drug delivery system. Nanoparticulate delivery system have been developed for good therapeutic effect with low toxicity Nanotechnology is concerned with development and utilization of structures and devices with development and utilization of structures and devices with organizational features at the intermediate scale between individual molecules and about 100 nm where nanoparticles occur as compared to bulk materials. The overall objective is to disseminate knowledge of the physical, chemical and biological phenomenon and processes in structures that have at least one length scale ranging from molecular to approximately 100nm (or submicron in some situations) and exhibit novel properties because of size. Use of carrier system in nanotechnology has added advantage of improved skin penetration, depot effect with sustained release drug action. As compared to conventional drug delivery system is more prominent and exhaustive. Nanotechnology has completely novel characteristic and application over others. Nanotechnology is a key technology leading to product innovation. Nanotechnologies use materials on an incredibly small scale so that they take on new properties compared to their larger form .The technology has the potential to transform many of the everyday consumer products that we use and wide range of product are already on the market. The focus of the article is on the specific properties, phenomenon and processes that are realized because of the nano size. Experimental and theoretical tool of investigation at nanoscale as well as synthesis, processing and utilization of particles and related nanostructure are integral part of this publication
纳米粒子被定义为大小在1到100纳米范围内的粒子,至少在三个维度中的一个。由于这种非常小的尺寸尺度,它们具有巨大的单位体积表面积,表面和近表面层中原子的比例很高,并且能够表现出量子效应。纳米技术是21世纪最有能力的技术之一。固体脂质纳米颗粒于1991年问世,是传统胶体载体(如乳剂、脂质体和聚合物微纳米颗粒)的另一种载体体系。纳米技术广泛应用于各种化妆品和皮肤产品,如口红、肥皂、抗皱霜、香水、牙膏等。纳米粒子是各种纳米技术应用的基本组成部分。纳米技术是目前安全有效的靶向给药技术之一。纳米技术涉及结构和器件的开发和利用,这些结构和器件在单个分子和大约100纳米之间的中间尺度上具有组织特征,其中纳米颗粒与块状材料相比存在。总体目标是传播物理、化学和生物现象和结构过程的知识,这些结构至少有一个长度尺度,从分子到大约100纳米(在某些情况下是亚微米),并由于尺寸而表现出新的特性。在纳米技术中使用载体系统增加了改善皮肤渗透,储存效应和缓释药物作用的优势。与传统给药系统相比更为突出和详尽。纳米技术具有完全不同于其他技术的特点和应用。纳米技术是引领产品创新的关键技术。纳米技术使用的材料规模小得令人难以置信,因此与它们更大的形式相比,它们具有新的特性。这项技术有可能改变我们使用的许多日常消费品,而且市场上已经有很多产品。本文的重点是由于纳米尺寸而实现的具体性能,现象和过程。研究纳米尺度的实验和理论工具,以及粒子和相关纳米结构的合成、加工和利用是本出版物的组成部分

Organo -phosphorus compounds have been imported to India since 1952 but we got awareness of the nature of these compounds when the Kerala food poisoning tragedy occurred in 1958. Organophosphorus compounds with effective control and eradication of the pets and insects affecting the plants and crops became a boon to agriculturist and horticulturists and they revolutionized agriculture and horticulture. In our country where agriculture is the main occupation of majority of the people in rural area, the organo-phosphorous pesticides have contributed their own share in bringing the green revolution The agriculturists who use these pesticides, commonly do not follow all the precautions during spraying and become victims of the accidental acute poisoning and sometimes of chronic poisoning. Population is also at risk of chronic poisoning from those agents by ingestion of vegetables etc which contain significant amount of these compounds when they are brought to the market. The number of people who consume these pesticides for suicidal purpose is in increasingly rapidly. Aim and Objects: To study the clinical features of the organo-phosphorus poisoning in patients coming to emergency ward.
自1952年以来,有机磷化合物一直进口到印度,但1958年喀拉拉邦食物中毒悲剧发生后,我们才意识到这些化合物的性质。有机磷化合物能有效地控制和消灭影响植物和作物的宠物和昆虫,成为农学家和园艺家的福音,它们彻底改变了农业和园艺学。在以农业为主要职业的我国农村地区,有机磷农药在带来绿色革命方面贡献了自己的一份力量。使用有机磷农药的农民在喷洒农药时通常不遵守所有的注意事项,成为意外急性中毒和有时慢性中毒的受害者。人们也有慢性中毒的风险,通过摄入蔬菜等,当它们进入市场时,含有大量的这些化合物。以自杀为目的使用这些农药的人数正在迅速增加。目的与目的:探讨急诊病区有机磷中毒的临床特点。

Over the past few decades, the photovoltaic industry has grown rapidly following the improvements in the efficiency and the demand for alternative energy resources. Commercial silicon photovoltaic with a power conversion efficiency of more than 20% plays a dominate role, but the high manufacturing cost is still a major issue for large-scale implementation. Many efforts have been made to reduce the cost of photovoltaic devices. There are huge demands for developing new electrode materials with lower cost and comparable performance. To date Graphene and Graphenederived materials have created an immense research interests due to its extraordinary physical and chemical properties, which delineated Graphene as an outstanding material for future electronics, optics, and energy-harvesting devices. This paper analyzes some of these properties of graphene & investigates whether graphene or graphene based materials can be a potential replacement for conventional materials used in solar cells or not. Graphene is a single atom thick two-dimensional material thus exhibit ~97.7% transmittance during the entire visible light spectrum. Graphene has unusual electronic transfer properties which follows the characteristic of 2D Dirac fermions, quantum hall effects. Electro catalytic actions of grapheme play a key role enhancing the efficiency of electro chemical solar cell like dye-sensitized solar cell (DSSCs), where the liquid/solid interface acts as a pathway for transfer electrons.
在过去的几十年里,随着效率的提高和对替代能源的需求,光伏产业得到了迅速发展。功率转换效率在20%以上的商用硅光伏占据主导地位,但制造成本高仍然是大规模实施的主要问题。人们已经做出了许多努力来降低光伏设备的成本。开发成本更低、性能相当的新型电极材料有着巨大的需求。迄今为止,石墨烯及其衍生材料由于其非凡的物理和化学性质而引起了巨大的研究兴趣,这使石墨烯成为未来电子、光学和能量收集设备的杰出材料。本文分析了石墨烯的一些特性,并研究了石墨烯或石墨烯基材料是否可以成为太阳能电池中传统材料的潜在替代品。石墨烯是一种单原子厚度的二维材料,因此在整个可见光光谱中具有~97.7%的透光率。石墨烯具有不寻常的电子转移特性,它遵循二维狄拉克费米子的特征,即量子霍尔效应。石墨烯的电催化作用对提高染料敏化太阳能电池(DSSCs)等电化学太阳能电池的效率起着关键作用,其中液/固界面是传递电子的途径。

Pyogenic granuloma (PG) is thought to represent an exuberant tissue response to a constant local irritation or trauma and it might be related to hormonal changes. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic growth, pedunculated or sessile, which usually bleeds on provocation. Pyogenic granuloma of the oral cavity is known to involve the gingiva more commonly (75% of all the cases). On rare occasion, it can be found extragingivally on lips, tongue, buccal mucosa, and palate which may mimic more serious pathological conditions such as malignancies. The purpose of this case report is to describe a rare case of extragingival pyogenic granuloma with an unusual proliferative appearance on the right buccal mucosa in a 65 years old female patient and its management using 810 nm diode laser.
化脓性肉芽肿(PG)被认为是组织对持续局部刺激或创伤的旺盛反应,可能与激素变化有关。临床上,口腔化脓性肉芽肿为光滑或分叶状外生生长,有带梗或无梗,通常在刺激时出血。口腔化脓性肉芽肿通常累及牙龈(占所有病例的75%)。在极少数情况下,它可以在嘴唇,舌头,颊粘膜和腭外发现,这可能模仿更严重的病理状况,如恶性肿瘤。本病例报告的目的是描述一个罕见的65岁女性患者右颊粘膜外脓性肉芽肿,其增生外观异常,并使用810 nm二极管激光治疗。

Purpose: To compare and evaluate 3-dimensional (3D) and conventional 4-hole miniplates fixation in the management of mandibular fractures. Materials and Methods: In 20 randomly selected patients who sustained mandibular fractures were selected for this study. Of the 20 cases, in 10 cases fractured fragments were stabilized using 2.0mm 3-Dimensional miniplates and in remaining 10 cases the fractured fragments were fixed with conventional 2.0mm miniplates. Post operatively cases were assessed clinically and radiographically at immediate post op, 1month and 3months. Results: This study suggests that fixation of mandibular fracture with 3D Plates provide three dimensional stability and carries low morbidity and infection rates. The only probable limitation of these plates may be excessive implant material due to the extra vertical bars incorporated for countering the torque forces and in cases where the fracture line passing through the mental foramina region. Conclusion: The 3D plate was found to be standard in Profile, strong yet malleable, facilitating reduction and stabilization at both the Superior and inferior borders giving three dimensional stability at fracture site. They seem to be an easy to use alternative to conventional miniplates. But the small sample size and limited follow up could be considered as the limitations of our study.
目的:比较和评价三维(3D)与常规四孔微型钢板固定治疗下颌骨骨折的疗效。材料与方法:随机选取20例持续性下颌骨骨折患者作为研究对象。20例中,10例骨折块采用2.0mm三维微型钢板固定,其余10例骨折块采用常规2.0mm微型钢板固定。术后病例分别于术后即刻、1个月和3个月进行临床和影像学评估。结果:本研究提示三维钢板内固定下颌骨折具有三维稳定性,发病率和感染率低。这些钢板唯一可能的限制可能是由于额外的垂直杆用于对抗扭力和骨折线穿过精神孔区而导致植入物过多。结论:该三维钢板轮廓标准,坚固且具有延展性,有利于上下边界的复位和稳定,使骨折部位三维稳定。他们似乎是一个容易使用的替代传统的迷你板。但样本量小,随访时间短是本研究的局限性。

Results: This study suggests that fixation of mandibular fracture with 3D Plates provide three dimensional stability and carries low morbidity and infection rates. The only probable limitation of these plates may be excessive implant material due to the extra vertical bars incorporated for countering the torque forces and in cases where the fracture line passing through the mental foramina region. Conclusion: The 3D plate was found to be standard in Profile, strong yet malleable, facilitating reduction and stabilization at both the Superior and inferior borders giving three dimensional stability at fracture site. They seem to be an easy to use alternative to conventional miniplates. But the small sample size and limited follow up could be considered as the limitations of our study.","PeriodicalId":14198,"journal":{"name":"International journal of recent scientific research","volume":"55 1","pages":"16839-16843"},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80184176","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}

Elevated YKL – 40 levels are seen in patients with type 2 diabetes.Interleukin-6 is one of the most studied inflammatory markers in periodontal disease. Aim was to estimate and compare GCF levels of YKL-40 and Interleukin-6 in healthy, chronic periodontitis and type 2 diabetes mellitus patients with chronic periodontitis.82 patients were enrolled into the study and divided into three experimental groups healthy group, chronic periodontitis group and chronic periodontitis with type 2 diabetes mellitus group. Gingivalcrevicular fluid samples were collected and YKL-40 and Interleukin-6 were analysed by enzyme linked immunosorbent assay. The total amount of YKL-40 and IL-6 in GCF were higher in patients with periodontal tissue breakdown. Within the limits of this study it can be concluded that YKL-40 in GCF may reflect the inflammation of periodontitis and can be a useful marker for inflammation in periodontal diseases and type 2 diabetes mellitus.
YKL - 40水平升高见于2型糖尿病患者。白细胞介素-6是研究最多的牙周病炎症标志物之一。目的是评估和比较健康、慢性牙周炎和2型糖尿病合并慢性牙周炎患者GCF中YKL-40和白细胞介素-6的水平。将82例患者分为健康组、慢性牙周炎组和慢性牙周炎合并2型糖尿病组。采集龈沟液,采用酶联免疫吸附法检测YKL-40和白细胞介素-6。牙周组织破裂患者GCF中YKL-40和IL-6的总量较高。在本研究范围内,GCF中的YKL-40可能反映牙周炎的炎症,可以作为牙周病和2型糖尿病炎症的有用标志物。
