    Notes: : The volatile compounds of sweetened condensed milk (SCM) were investigated to explain their contribution to SCM flavor. Commercially processed SCM was diluted with water and the volatiles were isolated by simultaneous steam distillation-extraction under reduced pressure. Commercial liquid milk was used for comparison. The odor concentrate was analyzed by GC and GC-MS, and then fractionated by silica gel TLC and preparative GC to determine the contributors to SCM flavor. Major volatile compounds were 10 fatty acids, 14 lactones, 10 ketones, 13 hydrocarbons, 8 alcohols, 4 aldehydes, and 8 miscellaneous compounds. δ-Decalactone and δ-dodecalactone were the principal contributors to SCM flavor although the other lactones may contribute as well.

    Inactivation of Vegetative Bacteria by Rapid Decompression Treatment (2002)

    Notes: : We investigated the inactivation and injury effects of hydrostatic pressure treatment combined with a slow decompression (SD treatment) and a rapid decompression (RD treatment) on several vegetative bacterial strains. Single decompression time for the SD and RD treatments was longer than 30 s and about 1 ms, respectively. The RD treatment gave significantly (P 〈 0.05) smaller D and z values than the SD treatment, showing that the RD treatment was more effective than the SD treatment in inactivating vegetative bacteria and in lowering the treatment pressure. It was suggested that a rapid decompression procedure could enhance the degree of pressure-mediated injury, which caused the higher bactericidal effect of the RD treatment.

    Deodorization of Fish Sauce by Continuous-Flow Extraction with Microbubbles of Supercritical Carbon Dioxide (2000)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 65 (2000), S. 0

    Notes: Volatiles were removed from fish sauce by continuous-flow extraction with microbubbles of supercritical carbon dioxide. The extraction was done at 35 °C and CO2/sample flow ratio of 0.14 and 0.29 under pressures of 10 to 30 MPa. After the treatment at a CO2/sample flow ratio, 0.29 at 10 MPa, remaining percentage ((the concentration in treated sample/that in untreated one) × 100) was 5.2% trimethylamine, 8.0% S-methyl ethanethioate, 30% dimethyldisulfide, 55 to 61% aliphatic aldehydes, and 25 to 42% carboxylic acids. The increase in CO2 flow rate improved the extraction efficiency significantly, but no effect of pressure was observed. The odor intensities of treated samples were between 1/4 and 1/8 of the untreated fish sauce.

    Inactivation Efficiency of Enzymes in Buffered System by Continuous Method with Microbubbles of Supercritical Carbon Dioxide (2002)

    Notes: : Continuous method with microbubbles of supercritical carbon dioxide (SC-CO2) was applied to enzyme inactivation in a buffer system, which has a buffer capacity similar to commercial liquid foods (natural juices, fruit drinks, Japanese sake). By continuous treatment with microbubbles of SC-CO2, α-amylase and acid protease were effectively inactivated rather than by heat treatments. Compared with the inactivation efficiencies of these enzymes in deionized water by continuous treatment with microbubbles of SC-CO2, that of α-amylase was slightly lower, but that of acid protease was not in the buffer system. These results suggest that this method enables the effective inactivation of enzymes, although inactivation efficiency by this method was affected by initial pH and the buffer action of samples.

    Inactivation Kinetics of Enzymes by Using Continuous Treatment with Microbubbles of Supercritical Carbon Dioxide (2001)

    Notes: Enzyme inactivation using a new apparatus for continuous treatment with microbubbles supercritical carbon dioxide (SC-CO2) was investigated. D value of a-amylase (5.0±1.2 min) subjected to microbubbles of SC-CO2 treatment (microbubbles-SCT) at 35 °C, 30 MPa was lower than that (227 ± 15.9 min) subjected to heat treatment (HT) at 70 °C. D value of acid protease was reduced by microbubbles-SCT at 50 °C, 30 MPa (15.4 ± 4.1 min), compared to HT at 50 °C (233 ± 15.2 min). The activation energy for the inactivation of acid protease (135 ± 8.3 kJ mol-1) by microbubbles-SCT was 1 half of that (259 ± 9.0 kJ mol-1) by HT. These results indicated that continuous treatment with microbubbles of SC-CO2 was effective for enzyme inactivation.

    Effect of initial concentration of bacterial suspensions on their inactivation by high hydrostatic pressure (2002)
    Oxford UK : Blackwell Science Ltd

    Notes: The effects of initial concentration [104–109 colony forming units (CFU) mL−1] on the inactivation of vegetative cell suspensions (Escherichia coli) and spore suspensions (Bacillus subtilis) by hydrostatic pressure treatment were investigated. The inactivation rates of E. coli and B. subtilis decreased as the initial concentration of cell and spore suspensions increased. In the practical application of hydrostatic pressure treatment, it was considered that the initial concentration of the bacteria suspensions should be as low as possible.

    Atrial natriuretic polypeptide in patients with subarachnoid haemorrhage due to aneurysmal rupture (1989)

    Notes: Summary Measurement of plasma alpha-humanANP (ANP) and antidiuretic hormone (ADH) in 28 cases with aneurysmal subarachnoid haemorrhage (SAH) was carried out, and then compared with control subjects who were infused with hypertonic saline. In cases with hyponatremia (HN), statistical correlation between control subjects and cases without HN was not evident with regards to ANP and plasma osmolality (Posm), excreted fraction of filtrated sodium (FENa) and urinary Na/K. Furthermore, they secreted supernumerarilly in spite of HN. Cases with HN were further subdivided into two groups, they were those cases with negative total sodium balance at the time of appearance of HN, and those cases without total negative sodium balance. In the former, central venous pressure had a tendency to decrease, however, secretion of ANP and ADH was statistically not different in either groups. It appears that ANP regulated urinary sodium excretion against an osmotic or sodium load acts as a maintenance of homeostasis as an osmotic regulator. Cases with HN in which secretion of ADH was physiological, ANP secreted supernumerarilly in spite of hypoosmonaemia and hypovolaemia. Our findings may contribute to a better understanding of the pathophysiological processes leading to hyponatremia in cases with cerebral disorders, and may help to improve the treatment possibilities.

    Notes: Summary Cisternal and/or ventricular cerebrospinal fluid (CSF) and arterial blood lactate and acid-base balance were measured serially in 38 patients with aneurysmal subarachnoid haemorrhage (SAH). Based on daily clinical assessment, the patients and accordingly the samples were divided into two groups according to the grading of the World Federation of Neurosurgical Societies (W.F.N.S.). In cisternal CSF, samples of Grade III–V showed significantly higher lactic acidosis than those of Grade I–II. The time course of lactate and pH in poor prognosis groups had a significant tendency of lactic acidosis, especially on the 5th, 6th, 7th day after SAH. Ventricular CSF lactate increased even without CSF acidosis in Groups III–V. Measurement of CSF lactate, especially from the cisterna magna is useful as an indicator of prognosis and changes of intracranial environment following SAH.

    Effect of albumin distribution (1989)

    Topics: Chemistry and Pharmacology
    Notes: Abstract The effects of altered albumin distribution on the apparent volume of distribution (V) and the apparent elimination rate constant (k) of drugs were investigated by a simulation analysis. The Equations derived by Øieet al. were modified for this purpose. Within the range observed in normal healthy subjects and patients, the change in albumin distribution significantly affectedV of drugs but, in general, notk. For drugs with more than 90% plasma-protein binding,V changed by more than 100%. The change in plasma-protein binding caused by an altered albumin distribution produced a greater effect onV than that caused by an altered albumin amount. These results suggest that albumin distribution is an important factor in controlling the kinetics of drugs which are highly bound to plasma protein. This is illustrated using midazolam as an example.
