Determination of in vitro antidiabetic effects of Zingiber officinale Roscoe

Aqueous extracts of Zingiber officinale rhizomes were studied to evaluate their antidiabetic effects on protein glycation and on the diffusion of glucose in vitro in the present study. Zingiber officinale rhizome aqueous extract were examined at concentrations of 5, 10, 20 and 40 g/L. The antidiabetic effects were found to be dose-dependent. Antidiabetic potential of Zingiber officinale was mainly through inhibition of the glucose diffusion and to a limited extent by reducing the glycation. However, further studies are needed to determine in vitro effects of therapeutic potential by restraining postprandial glucose absorptions and plasma protein glycations in diabetic subjects.Extratos aquosos de rizomas Zingiber officinale foram estudados para avaliar os seus efeitos antidiabéticos em glicação de proteínas e sobre a difusão de glicose in vitro, no presente estudo. Extratos aquosos de Zingiber officinale foram examinados nas concentrações de 5, 10, 20 e 40 g extrato de planta/L. Os efeitos antidiabéticos observados eram dependentes da dose. O potencial antidiabético de Zingiber officinale se verificou, principalmente, através da inibição da difusão de glicose e, em menor extensão, através da redução da glicação. Estudos adicionais são necessários para elucidar se efeitos in vitro representam potencial terapêutico, restringindo a absorção de glicose pós-prandial e a glicação de proteínas plasmáticas em indivíduos diabéticos

3D Miniature Antenna Design for RFID Applications in IoT Environment

The antenna application for internet of things (IoT) in urban infrastructure is introduced. Here, an effective design of microstrip 3D antenna for a RFID system in IOT which can also be used in narrow-band wireless communication is proposed. The antenna is combination of meander line techniques implemented with 3D structure resulted to miniature size of antenna that will be useful in many application. The critical parameters analysis and simulation results demonstrate the validity of the antenna with high gain and impedance matching are discussed as well

Synthesis of Iron Oxide (Fe3O4) magnetic nanocrystals by green chemistry approach

In the present study, we report the size distribution study on the iron oxide (Fe3O4) magnetic nanocrystals (NCs), which have been synthesized by using green chemistry approach with palm-oil based carboxylic compound (oleic acid) as capping ligands. The Fe3O4 NCs were prepared by one pot reaction under non-hydrolytic approach. With the assistance of oleic acid that plays the role as effective capping-ligands, we showed that the Fe3O4 NCs that are highly monodispersed in size and shape can be synthesized by scrupulously controlling the reaction time. The diameter of Fe3O4 NCs can be tuned within the range of 4.0-18.0 nm and exhibit very uniform morphology, which are spherical in shape. Current synthetic approach offers a cheap, environmentally benign and excellent repeatability route in large-scale production of high-quality magnetic Fe3O4 NCs if compared to the preceding reports
