Photochemical Reaction of Perillaldehyde under Various Conditions.

Bioscience, biotechnology, and biochemistry

Tateba H, Morita K, Kameda W, Tada M.
PMID: 27280657
Biosci Biotechnol Biochem. 1992 Jan;56(4):614-9. doi: 10.1271/bbb.56.614.

(-)-PeriIlaldehyde (1) was photoirradiated by a 400 W high-pressure mercury lamp under various conditions. In MeOH, 1 was degraded to give two new MeOH adducts (2 and 3) and a new methyl ether (4) under an N2 stream, while...

Quenching of singlet molecular oxygen (1O2) by azide anion in solvent mixtures.

Photochemistry and photobiology

Li MY, Cline CS, Koker EB, Carmichael HH, Chignell CF, Bilski P.
PMID: 11783930
Photochem Photobiol. 2001 Dec;74(6):760-4. doi: 10.1562/0031-8655(2001)074<0760:qosmoo>2.0.co;2.

The azide ion is a strong physical quencher of singlet molecular oxygen (1O2) and is frequently employed to show involvement of 1O2 in oxidation processes. Rate constants (k(q)) for the quenching of 1O2 by azide are routinely used as...

[The prevalence of sicca symptoms in Iceland.].

Atladóttir J, Guðmundsson OG, Holbrook P, Sigurðsson R, Gudbjornsson B.
PMID: 17018970
Laeknabladid. 2000 Dec;86(12):859-65.

OBJECTIVES: Sjoegren' syndrome is one of the most common inflammatory systemic rheumatic disorders. The syndrome is characterised by tiredness, pain problems and mucosal dryness. The goal of this study is to elucidate the prevalence of sicca symptoms in the...

Computer automated morphometric analysis of bull sperm heads.

Theriogenology

Gravance GG, Vishwanath R, Pitt C, Casey PJ.
PMID: 16727983
Theriogenology. 1996 Nov 01;46(7):1205-15. doi: 10.1016/s0093-691x(96)00291-9.

Morphological type classification of spermatozoa is an important component of the modern semen evaluation; however, current methods of analysis are subjective and highly variable between technicians. To reduce the subjectivity and thus variability of sperm morphology assessment, computer automated...

d-Glucose 6-Phosphate Cycloaldolase: Inhibition Studies and Aldolase Function.

Plant physiology

Loewus MW, Loewus F.
PMID: 16658312
Plant Physiol. 1973 Feb;51(2):263-6. doi: 10.1104/pp.51.2.263.

d-Glucose 6-phosphate cycloaldolase is inhibited 83% by 0.66 mm EDTA and stimulated 1.7-fold by 0.6 mm KCl. Dihydroxyacetone phosphate, an analog of the last three carbons in the proposed intermediate, d-xylo-5-hexulose 6-phosphate, acts as a partially competitive inhibitor. Treatment...

Analytical applications of ternary complexes-II Spectrophotometric determination of copper as rose bengal bisphenanthrolinium copper(II).

Talanta

Bailey BW, Dagnall RM, West TS.
PMID: 18959934
Talanta. 1966 May;13(5):753-61. doi: 10.1016/0039-9140(66)80011-5.

A ternary complex system, [(Cu.phen(2))Rose Bengal], is proposed for the determination of traces of copper ion. The reaction is rendered specific for copper amongst 56 cations and most anions by extraction of bis(2,9-dimethyl-1,10-phenanthrolinium) copper(I) from an EDTA medium. Because...

Non-specific seroreactions against Brucella abortus in ruminants in New Zealand and the presence of Yersinia enterocolitica 0:9.

New Zealand veterinary journal

Hilbink F, Fenwick SG, Thompson EJ, Kittelberger R, Penrose M, Ross GP.
PMID: 16031844
N Z Vet J. 1995 Oct;43(5):175-8. doi: 10.1080/00480169.1995.35884.

The level of non-specific reactions found in the brucellosis serology of ruminants in New Zealand was very low until July 1992. This changed when, in an export consignment of 1071 deer, 35% reacted in the Brucella abortus tube agglutination...

Analytical applications of ternary complexes-VI Spectrophotometric determination of trace amounts of palladium.

Talanta

Dagnall RM, El-Ghamry MT, West TS.
PMID: 18960440
Talanta. 1968 Dec;15(12):1353-7. doi: 10.1016/0039-9140(68)80194-8.

Extremely sensitive and specific colour reactions in both aqueous and organic solutions are described for the spectrophotometric determination of palladium(II) ions. The methods are based upon ternary complex formation with 1,10-phenanthroline or pyridine, and Rose Bengal Extra. Themolar absorptivities...

Structure Effect on Antioxidant Activity of Catecholamines toward Singlet Oxygen and Other Reactive Oxygen Species in vitro.

Journal of clinical biochemistry and nutrition

Shimizu T, Nakanishi Y, Nakahara M, Wada N, Moro-Oka Y, Hirano T, Konishi T, Matsugo S.
PMID: 21103026
J Clin Biochem Nutr. 2010 Nov;47(3):181-90. doi: 10.3164/jcbn.09-112. Epub 2010 Sep 16.

The reactivity of catecholamine neurotransmitters and the related metabolites were precisely investigated toward 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and reactive oxygen species. Catecholamines reacted immediately with DPPH radicals, their reactivity being stronger than that of ascorbic acid as a reference. Superoxide...

Electron paramagnetic resonance studies of dye-sensitized zinc oxide layers.

Applied optics

Larach S, Turkevich J.
PMID: 20076097
Appl Opt. 1969 Jan 01;8:45-9.

EPR studies of dye-sensitized zinc oxide layers constitute a valuable source of information, particularly when combined with other types of photoelectronic measurements. The EPR action spectrum, at 77 K, of zinc oxide sensitized with rose bengal correlates well with...

Antithrombotic Effect of a New Glycoprotein IIb/IIIa Antagonist, SC-52012A: Studies in two Guinea-pig Thrombosis Models.

The antithrombotic effect of a new platelet membrane GPIIb/IIIa antagonist, SC-52012A together with the 5-HT(2) receptor antagonist, ketanserin was studied in two guinea-pig thrombosis models. A segment of the femoral artery was occluded by a platelet-rich thrombus following photochemical...

Platelets. 1994;5(4):214-8. doi: 10.3109/09537109409006049.

We have developed a model whereby the femoral artery in an experimental animal can be occluded by a photochemical reaction between rose bengal and green light which causes endothelial injury followed by platelet adhesion, aggregation and formation of a...
