Solid phase fluoroimmunoassay of serum 11-deoxycortisol (17,21-dihydroxy-4-pregnene-3, 20-dione) was established using fluorescein isothiocyanate-labelled 11-deoxycortisol and anti-11-deoxycortisol antibody-conjugated polyacrylamide beads. 21-Amino-17-hydroxyprogesterone (21-amino-17-hydroxy-4-p...

High-content screening data derived from physiologically-relevant in vitro models promise to improve confidence in data-integrative groupings for read-across in human health safety assessments. The biological data-based read-across concept is especially applicable to bioactive chemicals with def...

A series of acetate ionic liquids were synthesized using a typical two-step method. The ionic liquids were used as environmentally benign catalysts in the production of propylene glycol ethers from propylene oxide and alcohols under mild conditions. The basic strengths of the ionic liquids were ...

ABSTRACT:Oxidative susceptibility testing was performed on a drug substance containing a methoxy-naphthalene moiety. 2,2′-azobisisobutyronitrile (AIBN) was employed to initiate peroxy radical oxidation to mimic autoxidation processes. In acetonitrile (ACN)–water solvents, three major degradati...

The yield of radiolytic degradation of 1-propanol is 13.3 ± 0.9 molecules/100 eV in a boiling state and 10.1 ± 0.9 molecules/100 eV in ambient conditions when irradiated with 8 MeV accelerated electrons. Boiling increases the yields of diols by 1.7 times and of heavy monohydric alcohols arisin...

A dynamic recirculation apparatus has been used to determine the isobaric phase equilibria of binary 1-propoxy-2-propanol mixtures with water and different alcohols (methanol, ethanol, 2-butanol and 1-hexanol). The systems exhibit both positive and negative deviations from Raoult’s law. No azeo...

H-bonding and non-specific interactions between dimethyl phthalate (DMP) and different human body substances were considered to be mainly responsible for various health dysfunctions. However, the manner of H-bonding and the adaptability of the structure of DMP that may underpin the H-bonding/non...

In this paper, we discuss a general methodology to make a compact design of the 1 GeV, 1 MW H- superconducting injector linac for the Indian Spallation Neutron Source (ISNS) project, by following the non-equipartitioned design approach, where the emittance growth of the beam is controlled throug...

A series of chiral compounds Cp*Ru(1-2,5-η-butadienesulfonyl)(L) (Cp* = C5Me5; butadienesulfonyl = CH2CHCRCHSO2) were prepared by treating Cp*Ru(1-5-η-CH2CHCRCHSO2) [R = H (1), Me (1Me)] with CO, P(OMe)3, a variety of phosphines, sulfur and nitrogen ligands. All addition reactions were selecti...

Charge-exchange reactions of H+, H2+ and H3+ at energies of 1–30 keV in sodium vapor were studied using the charge-exchange canal of a 2 × 1 MV tandem accelerator. Ion optics simulations were performed before measurements to ensure high beam transport efficiency in the beamline. The density of...

In this paper, experimental isobaric excess molar enthalpies for the binary mixtures of R-fenchone with butan-1-ol or pentan-1-ol at four temperatures (283.15, 298.15, 313.15 and 328.15) K and atmospheric pressure are reported over the entire composition range. They have been fitted to the Redli...

The standard (po = 0.1 MPa) molar energies of combustion, ΔcUmo, of 2-phenylindole, 1-methyl-2-phenylindole and 1-ethyl-2-phenylindole, in the crystalline state, were determined, at T = 298.15 K, using a static bomb combustion calorimeter. The vapour pressures as a function of the temperature f...

1-min rain rate is the key element to predict rain attenuation at a location precisely. However there is the limitation of 1-min rain rate availability in Malaysia for long term local measurement because rain rate statistics are commonly derived on the rain gauge recordings base with actual inte...

CuI doped selenite glass-nanocomposite system has been prepared using melt-quenching route. Their microstructure and electrical transport properties have been studied. It is observed from X-ray diffraction (XRD) study that the size of CuSeO3 nanocrystallite is found to be almost same, but the va...

Root plaques and cell wall components play important roles in regulating the uptake of heavy metals in rice plants. Proper doses of selenium (Se) can reduce heavy metal uptake in plants. Whether Se can influence both the formation of root plaques and the contents of root cell wall components to ...

Microbes play important roles in the transport and transformation of selenium (Se) in the environment, thereby influencing plant resistance to Se and Se accumulation in plant. The objectives are to characterize the bacteria with high Se tolerance and reduction capacity and explore the significan...

Two new complex selenite–chlorides of strontium and copper Sr2Cu(SeO3)2Cl2 (I) and SrCu2(SeO3)2Cl2 (II) were obtained and characterized by X-ray diffraction technique, DTA and IR spectroscopy. Both compounds crystallize in the monoclinic system I: Sp. gr. P21/n, a=5.22996(3) Å, b=6.50528(4) Å, ...
