Chemical characteristics, fatty acid composition, antioxidant and antimicrobial activities ofPrunus armeniaca kernel oil were evaluated in this study. The hexane extracts of kernel of P.armeniaca, which were collected from northwestern Iran, were obtained by Soxhlet apparatus.The fatty acids were derived to methyl esters and determined by gas chromatography/flameionization detector (GC/FID) and...

Bile salts of the coelacanth, Latimeria chalumnae, Smith, have been analyzed and shown to have three bile alcohols, latimerol, 5 alpha-cyprinol, and 5 alpha-cholestane-3 beta, 7 alpha,-12 alpha,25,26-pentol, two C24 bile acids, chenodeoxycholic acid and cholic acid, one C26 bile acid, probably 3 beta, 7 alpha, 12 alpha-trihydroxy-27-nor-5 alpha-cholestan-26-oic acid, and two C27 bile acids, 3 a...

In this work, the structural and electronic properties of folic acid molecule on functionalized (7,0)zigzag single-walled carbon nanotube was studied in gas phase on the basis of density functionaltheory (DFT). Furthermore, covalent interaction of folic acid with single-walled carbon nanotube wasinvestigated and its quantum molecular descriptors and binding energies were calculated. The DFTB3LY...

Various volatile organic compounds (VOCs) in breath exhaled by patients with lung cancer, healthy controls, and patients with lung cancer who underwent surgery for resection of cancer were analyzed by gas condenser-equipped gas chromatography-mass spectrometry (GC/MS) for development of an exhaled breath monitoring prototype system involving metal oxide gas sensors, a gas condenser, and gas chr...

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

V . O2 is identical to tissue V . O2. This is extremely diffi cult to achieve clinically, particularly in mechanically ventilated subjects. Also determination of V . O2 becomes progressively less accurate as FIO2 increases. Various alternative means of measuring V . O2 which overcome some of these diffi culties are available and may be more appropriate for clinical use. For example, a pneumotac...

Acid-base physiology is among the most complex topics in clinical medicine. Disturbances of this system are common in the critically ill, and important clinical decisions based on measured acid-base parameters occur on a daily, even hourly basis. Therefore, a sound understanding of acid-base physiology is mandatory for the intensivist. The field is full of complicated concepts and equations tha...

■ Fully automatic operation From the world’s first commercial CO2 membrane plant for CO2 recovery in EOR applications (Scurry Area Canyon Reef Operators [SACROC] oil field) to the world’s largest CO2 membrane plant for natural gas cleanup (1.28 Bcf/d, Cakerawala Gas Field Development—Petronas Carigali Hess Operating Company), Schlumberger continues to lead the industry with state-of-the-art CYN...

The CsrRS two-component regulatory system of group A Streptococcus (GAS; Streptococcus pyogenes) responds to subinhibitory concentrations of the human antimicrobial peptide LL-37. LL-37 signaling through CsrRS results in upregulation of genes that direct synthesis of virulence factors, including the hyaluronic acid capsule and streptolysin O (SLO). Here, we demonstrate that a consequence of thi...
