pH-Sensitive Nanoparticles for Cancer Therapy: Is this a Real Innovation in Nanomedicine?

In past decades, nanomedicine made impressive progress from basic science to clinical application. The goalof nanoparticles in nanomedicine is to develop systems capable of carrying, releasing and delivering their payload drugs in an efficient manner to target tissues.

pH-Sensitive Nanoparticles

Despite the important advances in nanotechnology and nanomedicine, these technological translations for new pharmaceutical products did not meet the expectations of the scientific community. The gap between the promising in vivo pre-clinical results and the outcome of clinical trials was not closed, and this continues to challenge researchers worldwide. As described previously in 2012 nanoparticles with sizes ranging from 30 nm to 200 nm can be specifically taken up by tumor tissues. This is a classical phenomenon, well known as the enhanced permeability and retention (EPR) effect.

Dependence of Biofuel Bio-refineries on Polymer Applications: The Outlook of Profitable Biofuel Opportunities

The strategies for production and processing of Bio-based nonpetroleum fuels from a variety of biomass are actively exploited in the recent years. Bio-polymerslike cellulose, starch, xylan, pectin etc. are renewables obtained from plants, algae and other biological sources that are being exploited for variety of applications in biofuels.

Biofuel lifecycle

Technologies for biological/chemical processing of these polysaccharides to form fuels, platform chemicals and other value added byproducts to enhance process profitability can be the next breakthrough in biofuel commercialization. In the early stages of biofuel revolution, plant polymers were promising targets for alcoholic fuel production.

Study on Antheraea perny Silk Fibroin Nanoparticles Carried Insulin

Chinese oak tasar Antheraea pernyi silk fibroin nanoparticles are a promising biomaterial for drug delivery because of its good properties, such as biodegradability and biocompatibility.

In recent decades, self-assembling nanoparticles derived from Antheraea perny silk fibroin have risen too much interest in application of drug delivery. In this paper, the Ca2+ in calcium gluconate induced self-assembling nanoparticles.

It was fabricated by blending aqueous Antheraea perny silk fibroin solution, calcium ion and insulin in a proper mixing ratio. The structure of the silk nanoparticles carried insulin was characterized by X-ray diffraction, FTIR and DTA.

Tubular Membrane Module-The Suitable Configuration for Pervaporation Desalination Membrane

Seawater desalination has been proved to be an efficient way to alleviate the global water crisis. Among major desalination technologies, membrane separation seems to be the most applicable and economic method because of its high efficiency, small footprint, energy saving, easily scales up etc.

Currently, membrane researchers focus on developing better reverse osmosis (RO) and membrane distillation (MD) membranes. RO is the dominate technology for membrane desalination.

However, it is difficult to treat high concentrated salt water due to the extremely high osmosis pressure. In a MD process, the driving force lies in the difference of the water vapor pressures between the membranes feed and permeate sides.

The Effects of Glyphosate and Multrazine on the Abundance and Diversity of Soil Microarthropods at the University Park

The effect of two herbicides, Glyphosate and Multrazine on the abundance and diversity of soil microarthropods (Mites and Collembolans) was assessed in a field experiment conducted from August to December, 2011 at the University of Port Harcourt, Nigeria.

The herbicides were applied at varying doses of low (1.4 ml/m2 active ingredient; a.i, standard (2.8 ml/m2 a.i) and high (5.6 ml/m2 a.i) for Glyphosate; and low (2.1 ml/m2 a.i), standard (4.2 ml/m2 a.i) and high (8.4 ml/m2 a.i) for Multrazine; and control was included.

The experiment was conducted in a split-plot design with six replicates arranged in a Randomized Complete Block Design. Moist soil samples were randomly collected from treated and control plots at the depths of 0-5 cm, 5-10 cm, 10-15 cm, and 15-20 cm, with an 8.5 cm2 diameter bucket-type auger.
