Persistence, leaching and associated toxicity risks of insecticide pyriproxyfen in soil ecosystem.

Pyriproxyfen is a pyridine-based insecticide used for pest control in fruits and vegetables. It is a potent endocrine disruptor and hormone imitator. Considering its potential hazards to non-target organisms and the associated environment, a lab study was conducted for assessing persistence, mobility in sandy loam soil and associated risk to various non-target organisms and soil enzymes.

Milk protein-based active edible packaging for food applications: An eco-friendly approach.

Whey and casein proteins, in particular, have shown considerable promise in replacing fossil-based plastics in a variety of food applications, such as for O susceptible foods, thereby, rendering milk proteins certainly one of the most quality-assured biopolymers in the packaging discipline. Properties like excellent gas barrier properties, proficiency to develop self-supporting films, adequate availability, and superb biodegradability have aroused great attention toward whey and other milk proteins in recent years. High thermal stability, non-toxicity, the ability to form strong inter cross-links, and micelle formation, all these attributes make it a suitable material for outstanding biodegradability.

Nanomaterials photocatalytic activities for waste water treatment: a review.

Water is necessary for the survival of life on Earth. A wide range of pollutants has contaminated water resources in the last few decades. The presence of contaminants incredibly different dyes in waste, potable, and surface water is hazardous to environmental and human health.

Aonla phytochemicals: extraction, identification and quantification.

Methanolic, ethanolic and ethyl acetate extracts of five aonla varieties were analyzed for phytochemical characterization using RP-HPLC. Five compounds viz. ascorbic acid, gallic acid, ellagic acid, ethyl gallate and quercetin were identified in aonla extracts by RP-HPLC at 270 nm.

Effect of processing treatment on nutritional properties and phytochemical contents of aonla () juice.

The present study was undertaken to evaluate physico-chemical composition and to study the effect of processing on phytochemical contents and nutritional components of anola juice prepared from Banarasi cultivar. Aonla juice pasteurized at 90 °C for 1 min showed better retention of phytochemicals as well as sensory characteristics. Methanol was used as a solvent for extraction of phytochemicals and reversed phase high performance liquid chromatography was performed to identify and quantify the phytochemical contents in juice extract.

Nutritional composition and drying kinetics of aonla fruits.

Drying kinetics and effects of drying on nutritional properties of 5 varieties of aonla were investigated using cabinet dryer. Thin shreds of aonla were spread in a layer in dryer and dried at varying temperature of 40, 50 and 60 °C till constant weight attained. Thin layer Newton model was proposed to study drying kinetic of aonla varieties.

Kozeny-Carman permeability relationship with disintegration process predicted from early dissolution profiles of immediate release tablets.

This study was oriented toward the disintegration profiling of the diclofenac sodium (DS) immediate-release (IR) tablets and development of its relationship with medium permeability k based on Kozeny-Carman equation. Batches (L1-L9) of DS IR tablets with different porosities and specific surface area were prepared at different compression forces and evaluated for porosity, in vitro dissolution and particle-size analysis of the disintegrated mass. The k was calculated from porosities and specific surface area, and disintegration profiles were predicted from the dissolution profiles of IR tablets by stripping/residual method.

Assessment of total polyphenols, antioxidants and antimicrobial properties of aonla varieties.

Phenolic content, antioxidant activities and antimicrobial activities of methanolic, ethanolic and ethyl acetate extracts of five different varieties of aonla () fruits as well their powders were evaluated. Total polyphenolic content in fresh aonla fruit extracts varied from 70.6 to 159.

Luteimonas padinae sp. nov., an epiphytic bacterium isolated from an intertidal macroalga.

A Gram-stain-negative, rod-shaped bacterium, forming yellow colonies and designated CDR SL 15T, was isolated from the surface of Padina sp., a brown macroalga, which grows in the Western coastal regions of the state of Goa, India. The 16S rRNA gene sequence phylogeny placed the strain in the genus Luteimonas and it showed closest sequence similarity to Luteimonas terricola BZ92rT (97.

A comparative evaluation of oral hygiene using Braille and audio instructions among institutionalized visually impaired children aged between 6 years and 20 years: A 3-monthfollow-up study.

Aim: The aim of this study is to compare the oral hygiene status among institutionalized visually impaired children of age between 6 and 20 years given with Braille and audio instructions in Raichur city of Karnataka.

Materials And Methods: A total of 50 children aged between 6 to 20 years were included in this study from a residential school for visually impaired children. These children were randomly divided into two equal groups.

Polymer Particulates in Drug Delivery.

Development of effective drug delivery systems is important for medicine and healthcare. Polymer particulates (micro- and nanoparticles) have opened new opportunities in the field of drug delivery by overcoming various limitations of conventional delivery methods. The properties of polymeric particles can be readily tuned by precisely engineering the constituent blocks of polymers for improving drug loading, release rate, pharmacokinetics, targeting, etc.
