: Following the September 11, 2001 terrorist attacks, letters containing Bacillus anthracis were distributed through the United States postal system killing five people. A complex forensic investigation commenced to identify the perpetrator of these mailings. A novel liquid chromatography/mass ...
Cytogenetic effects of two ionic contrast media (CM), Urografin 76% a sodium-meglumine diatrizoate, and Telebrix 38, a sodium-meglumine ioxythalamate, were tested on lymphocytes of patients undergoing brain CT Scan. Both compounds have approximately similar iodine concentrations. Chromosomal abe...
A highly sensitive high-performance liquid chromatography (HPLC) method for the determination of urinary N-acetylneuraminic acid (NeuAc) using 3-[(1-{[4-(5,6-dimethoxy-1-oxoisoindolin-2-yl)-2-methoxyphenyl]sulfonyl}pyrr olidin-2-yl)carbonylamino]phenylboronic acid as a fluorescent labeling reage...
The reliability of total sialic acid (TSA), lipid sialic acid (LSA) and free sialic acid (FSA) as markers in genitourinary malignancies was evaluated in 20 normal subjects, 21 patients with prostatic cancer, 22 patients with urinary bladder cancer and 14 patients with renal cell carcinoma. We i...
n-acetyl-d-neuraminic acid (Neu5Ac) aldolase (EC 4.1.3.3) has been reported for synthesis of Neu5Ac, 1 - 5 but there are no reports of processes which do not have significant drawbacks for large-scale operation. Here, Neu5Ac aldolase from an overexpressing recombinant strain of ...
The allylic resins are well known among thermosets for their excellent electrical characteristics and in particular for their ability to retain these properties under adverse environmental conditions. Properties are little affected on prolonged exposure to high temperatures, moisture and aqueous...
The allyl ester of dimeric acid polyamide, a compound which has a flexible unit in the main chain and reacts with the diallyl phthalate (DAP) resin to have an allyl group, was synthesized by the reaction of dimeric acid polyamide with allyl glycidyl ether. The allyl ester of dimeric acid polyami...
Sulfur‐containing allyl ester, which reacts with diallyl phthalate (DAP) resin to have allyl groups, was synthesized by the reaction of allyl phthalic acid with bisphenol having sulfur atoms. The sulfur‐containing allyl ester compound was blended with DAP resin to improve the adhesive properti...
The efficiency of two lypolytic enzymes (fungal cutinase, yeast esterase) in the degradation of dipropyl phthalate (DPrP) was investigated. The DPrP-degradation rate of fungal cutinase was surprisingly high, i.e., almost 70% of the initial DPrP (500 mg/l) was decomposed within 2.5 h and nearly 5...
This study set out to understand the sublethal effect of xenobiotic phthalate esters (PAEs) on the relationship between the susceptibility of shrimp to bacterial infection and the immune response of the shrimp. Neocaridina denticulate were exposed to different concentrations of the PAE dipropyl ...
A direct competitive chemiluminescent enzyme-linked immunosorbent assay (CL-ELISA) based on polyclonal antibodies with enhanced chemiluminescent detection of dipropyl phthalate (DPrP) has been developed. Hapten with an amino linker introduced on the target molecule was synthesized. Bovine serum ...
The absorption and fluorescence spectral properties of 2,6-diaminoanthraquinone (DAAQ) have been investigated in a series of organic solvents of different polarity and in aqueous solutions with H o /pH/H_ in the range −10 to 17. The Stokes shift of DAAQ is correlated with various polarit...
The role of solute–solvent and solvent–solvent interaction on the preferential solvation characteristics of 2,6-diaminoanthraquinone (DAAQ) has been analysed by monitoring the optical absorption and fluorescence emission spectra. Binary mixtures consist of dimethylformamide (DMF)–ethanol (EtO...
We present a valuable in situ fabrication process for synthesizing high electrical conductive polyimide/multiwalled carbon nanotube (PI/MWCNT) composite films. The success of this process was achieved the addition of 2,6-diaminoanthraquinone (DAAQ). The DAAQ is not only an excellent dispersion a...
A rapid and selective ultra performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was developed for simultaneous determination of three bioactive coumarins of Toddalia asiatica extract including pimpinellin, isopimpinellin and phellopterin in rat plasma for the first t...
BACKGROUND Dimethyl phthalate (DMP) is refractory, persistent and easy to enrich in anaerobic environments. The urgent need to degrade this refractory organic matter with high efficiency can be met by bioelectrochemical technology. In this paper, the degradation characteristics of DMP under diff...
Dimethyl phthalate (DMP), a member of the phthalate esters (PAEs), is a common contaminant and frequently detected in soil. In this study, metagenomics revealed that DMP contamination in a Mollisol led to alterations in biological genomes and pathways identified using the Kyoto Encyclopedia of G...
BACKGROUNDIn this work, the electrolysis of dimethyl phthalate (DMP, a widely‐use plasticizer) with conductive‐diamond anodes is studied.RESULTSResults show that this technology is capable of depleting this pollutant in a wide range of initial concentrations. Although mass transfer limits the ...
The transformation of protopines into berbines under improved conditions has been used to synthesize 1-methoxystylopine. Coulteropine, the main alkaloid from Romneya coulteri, was used as the starting protopine to accomplish the stereocontrolled synthesis of both cis and trans N-methyl-1-methoxy...
