2014 X-ray scattering patterns of ionic micellar solutions contain both interand intramicellar interferences. We show that these two terms can be separated according to the method developed by Hayter and Penfold. Both X-ray and neutron scattering signals are predicted on an absolute scale by a unique model of chain packing. Examples of results obtained through an incomplete separation of interm...

1. The precipitation of the proteins of calf-thymus nucleohistone and herringsperm nucleoprotamine with the salts of fluorine-containing carboxylic acids has been studied. Pentadecafluoro-octanoate gave a precipitate that could be sedimented almost completely by centrifuging at 2350g for 20min. omega-H-Hexadecafluorononanoate, omega-H-eicosafluoro-undecanoate and dodecyl sulphate gave precipita...

Genes responsible for the synthesis of poly(3-hydroxybutyrate) (PHB) in Azotobacter sp. FA8 were cloned and analyzed. A PHB polymerase gene (phbC) was found downstream from genes coding for beta-ketothiolase (phbA) and acetoacetyl-coenzyme A reductase (phbB). A PHB synthase mutant was obtained by gene inactivation and used for genetic studies. The phbC gene from this strain was introduced into ...

AIM Identification of cyclopropyl fatty acids in walnut oil. METHOD GC/MS method was developed for the determination of eight cyclopropyl fatty acids in walnut (Juglans regia) oil. RESULTS Monocyclopropane acids: methyl 9-cyclopropyl-nonanoate, 6,7-methylene-, 8,9-methylene-, 9,10-methylene-, 11,12-methylene octadecanoates, and dicyclic acid - methyl 9,10,12,13-dimethylene octadecanoate, tr...

A 48-year-old male presented to our hospital with pyrexia and general fatigue. The patient was diagnosed with influenza A virus infection, and then given laninamivir octanoate hydrate. Eleven days after onset, he noticed bilateral swollen submandibular glands. He visited our hospital again, and underwent blood examination and cervical computed tomography (CT). CT indicated that bilateral subman...

A headspace-proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF/MS) system that combines PTR-TOF/MS with a dynamic and reactive flavor-release monitoring was constructed to measure the orthonasal aroma components in beer before after foaming. Some headspace of foaming real time, such as m/z 145.1150 173.1536, are thought be derived mainly from ethyl hexanoate octanoate, respectiv...

Dry-cured meat products are considerably popular around the world due to unique flavor. Proteolysis is one of enzymatic reactions from which flavor substances derived, affected by endogenous proteases. The purpose aimed reveal potential relationship between proteases and key in dry-cured pork coppa this paper. dynamic changes activity, free amino acids, volatiles during processing were characte...
