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.

Nanomedicine
The goal of nanoparticles in nanomedicine is to develop systems capable of carrying, releasing and delivering their payload drugs in an efficient manner to target tissues.

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 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.

Glyphosate and Multrazine
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.

In Vitro Ovicidal and Larvicidal Activity of Aqueous and Methanolic Extracts of Ziziphus Mucronata Barks Against Haemonchus Contortus

Ziziphus Mucronata Barks
Haemonchus contortus is one of the most pathogenic nematode parasites in small ruminants’ worldwide. Anthelmintic resistance and high cost of drugs has prompted evaluation of medicinal plant extracts which can be used as alternative drugs.

The objective of this study was to evaluate in vitro ovicidal and larvicidal activity of aqueous and methanolic extracts of Ziziphus mucronata barks against H.

contortus stages isolated from a sheep in Kenya. Barks of Z. mucronata were collected from Chad, air-dried, ground and extracted with methanol and distilled water.

Magnetic micro-particle immune separation combined with enzyme linked immunosorbent assay for quick detection of Salmonella typhimurium in raw eggs

Magnetic micro-particle immune separation

An immunomagnetic separation (IMS) method was developed for separating Salmonella typhimurium bacteria from large-volume samples of raw eggs.

An egg was homogenized with a blender. The homogenized egg material was diluted with DI water to make a 200 mL sample mixture. Anti-Salmonella typhimurium antibody coated magnetic micro particles (MMP) were used to trap the Salmonella bacteria in the sample mixture.

The Salmonella-trapped MMP were separated from the egg sample matrices by using a large magnet. An enzyme-linked immunosorbent assay method was adopted and revised for detecting the bacteria trapped onto the MMP.

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

Biofuel Bio-refineries on Polymer Applications

The strategy for production and processing of Bio-based nonpetroleum fuels from a variety of biomass is actively exploited in the recent years.

Bio-polymers like 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.

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.

Role of Nanomaterials and their Applications as Photo-catalyst and Senors | A Review

Lack of environmental sustainability is a vital and growing problem due to the issues: such as climate change, pollution, and disturbances associated with biodiversity. A major cause of these environmental threats is pollutants in the atmosphere.

Nanomaterials
Semiconducting metal oxide nanostructures play an important role in developing smart materials that are well efficient for sensing and simultaneously destroy harmful chemical contaminants from our environment.

This review article highlights some recent advances of nano-science in the area of environmental hazardous contaminant detection by sensing followed by the remediation; focused on water remediation especially through photo-catalysis
