Despite the variety of modern molecular techniques available, examination of foetal anatomy is still a fundamental part of teratological studies in evaluating the developmental toxicity of xenobiotics or other non-chemical factors. The article presents contemporary methods of embryotoxicity and foetotoxicity assessment. A single alizarin red S and double alcian blue followed by alizarin red S s...
Raman microspectroscopy is a powerful analytical technique in cultural heritage. However, results are often compromised by luminescence interference and poor sensitivity. Surface-enhanced spectroscopy (SERS) an alternative that can enhance the signal quench luminescence, but interaction of analyte metal substrate produces altered spectra. Shell-isolated nanoparticle-enhanced (SHINERS) promising...
In this contribution, the amounts of Ni (nickel) and Al (aluminum) in tilapias (Oreochromis niloticus) were determined using square wave voltammetry (SWV) with glassy carbon working microelectrode with a mercury thin film, platinum counter electrode, and Ag/AgCl reference electrode. Ni was studied through the formation of the dimethylglyoxime-Ni (Ni-DMG) complex, while Al was studied through th...
Article history: Received 9 July 2017 Received in revised form 8 October 2017 Accepted 13 November 2017 Available online 21 November 2017 The analysis by intense radiation sources of paintingmaterials used in artworks gives valuable information about their composition and state of conservation, but it can also induce undesired modifications on the studied substrates. Here we use X-ray photoelec...
Alizarin red, confocal laser scanning microscopy, dentinal tubules, human caries. Abstract Dentin morphology and the lesion found in dental caries have been studied for many years. It was first observed under optical microscopy, and later using electron microscopy. Confocal laser scanning microscopy (CLSM) applied with several fluorescent dyes such as alizarin red to see normal dentinal tubules...
background & aim: rubiatinctorum is one of the most well-known medicinal plants whose alizarin and other anthraquinones which are outstanding color agents with some trace of pharmaceutical properties are isolated from it. the objective of this study was to optimize alizarin production in intact plant of r.tinctorum by induction with biotic elicitors. experimental: to increase the synthesis ...
abstract purpose: skeletal staining is a way to study the effect of many chemical or herbal substances on development of bones and cartilages in order to record the level of probable deformity.this article aimed to present a modified protocol to make all skeletal studies on laboratory animals possible. materials and methods: the important notes about skeletal staining were fixing by ethanol and...
