stereoisograms of octahedral complexes are classified into five types (type i--typev) under the action of the corresponding rs-stereoisomeric group. their enumeration is accomplished in a type-itemized fashion, where fujita's proligand method developed originally for combinatorial enumeration under point groups (s. fujita, theor. chem. acc., 113, 73--79 (2005)) is extended to meet the requireme...

A proof for the existence of five stereogenicity types, which has once been demonstrated intuitively by means of stereoisograms, is mathematically given on the basis of the five factor groups derived from RS-stereoisomeric groups. These factor groups are proved to correspond to five types of subgroups appearing in RS-stereoisomeric groups. Thereby, the relationship between the concept of chiral...

The efficient synthesis of two new stereoisomeric 3-aminocyclooctanetriols and their halocyclitol derivatives starting from cis,cis -1,3-cyclooctadiene are reported. Reduction cyclooctene endoperoxide, obtained by photooxygenation -1,3-cyclooctadiene, with zinc yielded a diol followed acetylation the hydroxy group, which gave dioldiacetate OsO 4 /NMO oxidation. cyclooctane prepared was converte...

7a-(Methoxycarbonyl)-N-methyl-1,3a,5,6,7,7a-hexahydro-4H-1,4,6-(epiethane[1,1,2]triyl)indene-4,9-dicarboximide has been prepared through a modification of a previous synthetic sequence, in which the benzyloxymethyl hydroxyl protecting group has been replaced by methoxymethyl, to avoid the apparent formation of a benzyl ester derivative as a side product. The overall yield of the new synthetic s...

This study was conducted to examine effects of resistant starch compared to fructooligosaccharide (FOS) and zinc bacitracin (ZnB), on performance and ileum morphology in broilers. The experiment groups included a control (basal diet with no additive; CON), four groups receiving different levels of resistant starch type 2 (1, 2, 3, and 4% added to basal diet; RS), a group receiving fructooligosa...

OBJECTIVES the aim of our study was to evaluate the activity of superoxide dismutase (SOD) and the levels of glutathione (GSH), malondialdehyde (MDA), and nitric oxide (NO) in liver and kidney tissues in a rat model of convulsive seizure induced by single and repeated doses of pentylenetetrazole (PTZ) and sound stimulation with key ringing. MATERIALS AND METHODS male Wistar adult rats (n=48),...

AIM The 21-gene recurrence score (RS) predicts a clinical benefit of chemotherapy for individuals with ER-positive/HER2-negative breast cancer. Using in vitro chemoresponse assay, we compared the chemosensitivity according to RS in these patients. METHOD Among the patients with Oncotype Dx assay, we identified 63 patients who had chemotherapy response assays to doxorubicin based on adenosine ...
