Phytanic acid (3,7,11,15-tetramethylhexadecanoic acid) (Phyt) is a saturated branched chain fatty acid which originates after the breakdown of chlorophyll molecule, phytol. It plays an important role in a variety of metabolic disorders with peroxisomal impairments. The aim of our investigation w...

Using the regression model building the relationships between the concentration of 37 fatty acids of blood plasma phospholipids of 41 patients with coronary artery disease after coronary stent implantation, the inflammatory response and oxidative stress markers were estimated. The dynamics of th...

Anteiso-fatty acids (aFAs) are chiral molecules due to a methyl substituent on the antepenultimate carbon of the otherwise straight acyl chain. 12-Methyltetradecanoic acid (a15:0) and 14-methylhexadecanoic acid (a17:0) are the predominant aFAs in nature but their individual contributions e.g. to...

A study has been initiated to investigate the behavior of mixed straight-chain/iso-branched-chain fatty acid monolayer systems. In this publication we examine the effects of changing the iso-branched chain length while maintaining the chain-length of the straight-chain fatty acid constant. Three...

1,3-Octadiene, 1,3-heptadiene, and 5-methyl-1,3-hexadiene were polymerized with the catalytic systems AlEt2Cl–Nd(OCOC7H15)3–Al(iBu3), CoCl2(PtBu2Me)2–MAO, and CoCl2(PiPrPh2)2–MAO, obtaining novel stereoregular polymers, never reported before, having isotactic cis-1,4, syndiotactic cis-1,4, a...

A new 1-hexadecylammonium-polyoxomolybdate composite thin film has been successfully prepared by the supramolecular template method. The film was lamellar in structure, and the main product in the film was identified to be (C16H33NH3)4Mo8O26. The composite film shows photochromism in the violet ...

A discontinuous polyacrylamide gel system operating at pH 4.0–1.5 which resolves proteins bearing base labile groups extracted from intact cells is described. It uses potassium phosphate buffer in the running and stacking gel and glycine as the trailing ion component. Proteins are solubilized w...

A two dimensional preparative polyacrylamide gel electrophoresis system is described which has both high resolving power and high loading capacity (approximately 100 mg protein). The first dimension is electrophoresis toward the cathode at acid pH in the presence of the cationic detergent benzyl...

The rheological properties of aqueous solutions and films made from blends of polyvinyl alcohol (PVOH) and amylose-hexadecylammonium chloride inclusion complexes (Hex-Am) were investigated to better understand the polymer interactions and processing parameters. Aqueous solutions of Hex-Am displa...

Water soluble amylose-hexadecyl ammonium chloride complexes were prepared from high amylose corn starch and hexadecyl ammonium chloride by excess steam jet cooking. Amylose inclusion complexes were spray dried to determine the viability of spray drying as a production method. The variables teste...

The cis and trans isomers of 2-benzoylcyclopropanecarboxylic acid interconvert in refluxing alkaline solution with accompanying exchange of hydrogen in the 2-position and with retention of one asymmetric center. The photochemical conversion produces inactive trans acid from optically active cis ...

Behavioral and electrophysiological comparative analyses of the effects of 2-o-chlorobenzoyl-4-chloro-N-methyl-Nα-glycylglycinanilide hydrate (45-0088-S) and diazepam on the CNS were performed with eats and monkeys. No essential difference between 45-0088-S and diazepam on the effects in the CN...

Thioureas are important sulfur and nitrogen containing compounds and they are useful substances in drug research. In an effort to improve potential anticancer activities, two novel 1-benzoyl-3-methyl thiourea derivatives were designed and synthesized with substitution at aromatic positions of C-...

In this report the steady-state optical absorption and ligand rebinding kinetics of Fe(II)protoporphyrin IX (Fe(II)PPIX) and (CO)Fe(II)PPIX in tetramethylene sulfoxide (TMSO) are examined. The equilibrium optical absorption spectrum of Fe(II)PPIX in neat TMSO is characteristic of heme iron that ...

In this paper we report the synthesis and characterization of the following ruthenium(II) and ruthenium(III) complexes with tetramethylene sulfoxide (TMSO): cis-RuCl2(TMSO)4 (1), trans- RuCl2(TMSO)4 (2), the corresponding dibromo derivatives cis- and trans-RuBr2(TMSO)4 (3 and 4, respectively), (...

Aryl azides have been found to add to unactivated olefins, providing a convenient route to alkyl subsituted triazolines. Similarly, conjugated dienes undergo cycloaddition with azides to give 5-vinyltriazoline derivatives. The orientation of the additions accords with previously reported mechani...

Mice were immunized for contact sensitivity and antibody production by painting the skin with picryl chloride. Lymph node and spleen cells taken 4 days later transferred contact sensitivity. However, cells taken at 7–8 days failed to transfer but were able to block the transfer by 4 day immune ...

The kinetics of lymphocyte function associated antigen 1 (LFA-1) expression on spleen cells (SPC) and liver non-parenchymal cells (NPC), and intercellular adhesion molecule 1 (ICAM-1) expression on hepatocytes (HC) was examined in acute liver injury mice induced by a DTH reaction to picryl chlor...

In this work, we have achieved an sp3 carbon-enriched, antifouling hydrophobic electrode surface using a one-pot n-butylsilane reduction method. The carbon surface was initially obtained by pyrolysis of C2H2 on a quartz substrate. Using Raman spectroscopy, cyclic voltammetry and electrochemical ...

To investigate the seasonal distribution of mercury (Hg) in precipitation in Seoul, Korea, event based total mercury (THg) and methyl mercury (MeHg) in precipitation samples were collected for one year. During sampling periods, volume weighted mean (VWM) concentration of THg and MeHg were 16.91 ...
