This paper discusses the potential of Pseudomonas aeruginosa in treating aluminium containing wastewater and aluminium recovery potential from the produced biomass. The species of P. aeruginosa was isolated from aluminium contaminated site. This isolate had characteristics of acid resistant up t...
In this paper, we describe a rapid, low-cost and highly sensitive colorimetric method for the detection of isoprenaline, based on 2-amino-5-mercapto-1,3,4-thiadiazol (AMTD) functionalized gold nanoparticles (AMTD-AuNPs) as a sensing element. Hydrogen bonding interaction between isoprenaline and ...
Full atomistic molecular dynamic (MD) simulations and quantum mechanics (QM) calculations were carried out to investigate the aggregation process of the pure and functionalized gold nanoparticles (AuNPs). On the basis of the obtained results, pure AuNPs are not stable in water, while 1‑(2‑mercap...
In this study, we examine the inflation hedging potential of the two most valuable precious metals namely gold and palladium. Our data covers a wide range of OECD countries which currently account for over 70 per cent of the demand for both precious metals. We employ both time series and panel d...
A DFT-level study on neutral or charged Aun clusters at relativistic and non-relativistic (R/NR) levels confirms the previously suggested relativistic origin of the planar structures. In addition, a number of potentially new aspects are observed: (1) The symmetries with a large relativistic cont...
This study investigates whether the role of gold changes due to the introduction of gold exchange-traded funds (ETFs) using sample data of seven countries in which physically-backed gold ETFs have been issued. The results show that the traditional roles of gold do change after the introduction o...
The paper examines the relative efficiency of gold Exchange Traded Funds (ETF) against spot gold and gold futures in Indian scenario using a series of conventional and threshold cointegration statistics. The results reveal that gold ETFs and spot gold as well as gold ETFs and gold futures conver...
In this paper, we designed a novel organic-inorganic nanohybrid electrochromic material through tethering polyaniline and gold colloids with an interfacial coordinate bond. The enhanced electrochemical and electrochromic properties were expected owing to the high conductivities of the gold collo...
This paper examines the properties of the gold risk premium. We estimate a parsimonious model for the gold risk premium and uncover important time variations in the dynamics of the risk premium. We also estimate the risk premia of the stock and bond markets and investigate their co-movements. Th...
Olsalazine sodium, salicylate derivative (prodrug) is effectively bioconverted to mesalazine (5-aminosalicylic acid; 5-ASA), which has an anti-inflammatory activity in ulcerative colitis. In this article, a novel highly sensitive and selective method was developed and validated to determine mesa...
Traditional medical treatments for ulcerative colitis (UC) are still compromised by its adverse effects and not potent enough to keep in remission for long-term periods. So, new therapies that are targeted at specific disease mechanisms have the potential to provide more effective and safe treat...
The first two three-dimensional (3D) pillared metal–olsalazine complexes, namely [Co(osa)0.5(bim)0.5(H2O)] (1) and [Cd(osa)0.5(bim)0.5(H2O)] (2) (H4osa = 3,3-azo-bis(6-hydroxybenzoic acid), bim = 1,4-bis(imidazol-1-yl)butane) have been hydrothermally synthesized and further characterized by sin...
PurposeTo compare the degradation kinetics of metronidazole and olsalazine by the bacteria of ascending colon and the bacteria of feces of healthy adults.
Hyperuricemia, a long-term purine metabolic disorder, is a well-known risk factor for gout, hypertension and diabetes. In maintaining normal whole-body purine levels, xanthine oxidase (XOD) is a key enzyme in the purine metabolic pathway, as it catalyzes the oxidation of hypoxanthine to xanthine...
PurposeEvaluate ex vivo the bacterial metabolism induced degradation rates of mesalamine (negative control), metronidazole and olsalazine in distal ileum and in cecum.
In this work, the supramolecular host-guest interaction of the prodrug Olsalazine (OLZ) and β-Cyclodextrin (β-CD) was examined experimentally and computationally. Experimentally, employing the UV–Vis spectroscopic method in aqueous media at various pH's, results obtained using the Benesi...
Click Cu(I)-catalyzed polymerization of diynes and diazides was performed to obtain a novel type of linear copolymer, which were prepared from monomers derived from poly(ethylene glycol), 5, 5′-azodisalicylic acid [olsalazine] and 1,4-butanediol diglycidyl ether. The resulting copolymers will c...
Colon-specific drug delivery systems are efficient for increasing the availability of drugs at colon region and are desirable for the treatment of local diseases such as ulcerative colitis and colonic cancer. We synthesized an acryloyl chloride modified olsalazine (olsalazine-AC) as an azo cross...
Single spherical beryllium particles from two powder samples having average particle diameters of 32 and 25 μ, respectively, were injected into oxidizing gases, both moist and dry, at atmospheric pressure and at temperatures ranging from 2600°–2960°K. The purpose was accurate measurement of ...
An experimental investigation of propane and six other quench gases was carried out in argon-filled proportional counters. The objective of the study was to find the best gas mixture for optimizing the gas gain and the energy resolution as well as to understand the role of the ionization potenti...
