The Use of Silver Nanoparticles Prepared by The Green Method to Reduce The Concentration of Nickel in Water
The present work aims to study a convenient and environmentally friendly method for the green synth of silver nanoparticles (AgNPs based on lemon juice extract. The biomolecules contained in lemon extract act as self- reducing and stabilizing agents. The optimal solution for the synthesis of AgNPs was determined by varying silver nitrate concentrations. A surface plasmon resonance system identified the synthesized silver nanoparticles by their color change from colorless to dark brown. Silver nanoparticles synthesized were characterized by Uv-visible (UV-Vis) spectroscopy, high-resolution transmission electron microscopy (HR-TEM), and FTIR spectroscopy. As a result of UV-visible spectroscopy, surface plasmon resonance (SPR) can be determine
Different types of Glutaredoxins (GRXs) that play a major role in cellular anti-oxidative reactions have been studied for their structure and function from various organisms. Glutathione (GSH), an anti-oxidant with several medical benefits, binds to GRXs. This work has structurally characterized GRX2 from C. reinhardtii (CrGRX2) using biophysical, molecular modelling, and isothermal titration calorimetry (ITC) techniques. CrGRX2 adopts the classical GRX-Trx fold consisting of five β-strands surrounded by four α-helices that bind to GSH with moderate strength through a cysteine residue. The residues involved in the interaction closely match with those observed for E. coli and human counterparts, indicating that the cellular GSH-GRXs antioxidant system is highly conserved.
Structural, Elemental and Molecular Characterization of Normal And Osteoarthritic Human Articular Cartilage
The articular cartilage overlying the bone consists of a network of collagen fibres. This network is essential to cartilage integrity, usually suffering damage in degenerative joint diseases such as osteoarthritis. We have been applying a number of techniques to study the bone-cartilage interface and of changes occurring in this with disease. The bone-cartilage samples with disease were investigated for their structural, elemental and molecular properties. The bone-cartilage samples with disease were characterized by scanning electron microscopy- energy dispersive X-ray spectroscopy (SEM-EDX) and Fourier Transform infrared spectroscopy (FTIR) and Fourier transform (FT) Raman spectroscopy.
France, Greece, Italy, and Spain the major sheep and goat milk producers in Europe, got the initiative through an interim of 30 years (1985 – 2015), to organize - through IDF - 7 symposiums aiming at the upgrade of the Dairy Sector. One major interest was the milk quality. Stepwise, the efforts followed cow milk structural development in organizing the testing laboratory, the definition of quality in composition (fat, protein, lactose, total solids), in Hygienic (Total Bacteria Count, Somatic Cell Count, antibiotics residues and Aflatoxin M1 contamination), adulteration with water and detection of milk species. EU, by Decision 2002/657/EC, defined the rules for the Directive 96/23/EC, enumerated the testing methods, the demands in sampling procedures, the minimum limits of performance, the quality control (ISO 17025) and the interpretation of results. The equivalency of results from different laboratories, through ISO 17025, demanded the application of ISO analytical standards.
Cefpodoxime proxetil (CFPD PRXL) is broad spectrum, third generation cephalosporin; antibiotic. It is extremely bitter taste resulting in poor patient compliance. The aim of the present work was to prepare drug resin complex (DRC) using ion exchange resin (Kyron T-114) for taste masking and formulate oral reconstitutable suspension of DRC.
A series of differentiated 2-chloroquinoline derivatives (3-26) having various spacer groups between 2-chloroquinoline and aryl or heteroaryl ring were synthesized by chemical reactions involving nucleophilic addition, nucleophilic substitution, esterification and cyclization.
Here in a systematic, accurate and reliable method, Head-Space Gas Chromatography-Mass Spectrometry (HS-GC/MS) was developed to determine blood carboxyhemoglobin (COHb%), in order to investigate deaths related to CO exposure especially involving blood and hepatic tissues.
Human odor detection technologies have drawn attention due to the wide possibility of potential applications they open up in areas such as biometrics, criminal investigation and forensics, search for survivors under rubble, and security checkpoint screening. Gas chromatography/mass spectrometry (GC/MS) has been the most successful and powerful analytical approach developed to date for human odor analysis, and hundreds of human odorants have been identified using this tool.
