The studies were carried out in a flow catalytic device the stationary phase of catalyst (catalyst volume 6 cm3), at 450–6000C, normal atmospheric pressure (P = 0.1 MPa), was under conditions which volumetric velocity initial gas mixture 600–1000 h-1. Qualitative and quantitative composition propane-butane fraction reaction products analyzed on chromatograph “Chromatic-Crystal 5000M” following ...

X, which respectively have 2-amino-adenine, guanine, hypoxanthine, xanthine as the base moiety5). HB611 cells were maintained in DMEM (Gibco) supplemented with 10% fetal bovine serum (General Scientific Laboratories), 100 ^g/ml of streptomycin, 100IU/ml of benzylpenicillin (Gibco) and 200 jug/ml of geneticin (Gibco) at 37°C in 5% CO2 -95% air. The cells were seeded in 35-mrn CORNING wells at a ...

A sensitive, selective and reliable liquid chromatography-mass spectrometry coupled with electrospray ionization interface method for simultaneous separation and determination of thymine, adenine, adenosine and cordycepin in Cordyceps sinensis has been established. The optimum separation for these analytes was achieved using a gradient elution system and a 2.0 x 150 mm Shimadzu VP-ODS column. 2...

Present study screened ten Cyanobacterial extracts for antimicrobial activity, cytotoxicity (against human cervical carcinoma cells Hela and SiHa) & GC-MS for chemical composition. Cyanobacterial extracts were subjected to Agar Well Diffusion Assay at concentration of 100μg. well -1 and incubated at 37 + 2 o C. Inhibition zone was measured in millimetres (mm) after 18-24 hour. Minimum inhibitor...

The qualitative study on the efficiency of anti-caking and antioxidant additives as long-term thermal stabilizers for polypropylene (PP) using ATR-FTIR spectrometry is reported. Different kinds of additives are used in polymeric materials both for processing, for long-term stabilization and to prevent deterioration of the plastics performance. ATR-FTIR technique is one of the most important spe...

Hydrogenperoxide (H(2)O(2)) is an end product of diamine and polyamine oxidation by their respective oxidase enzymes. A new sensitive assay method is based on a H(2)O(2)-titanium (Ti) complex formation as an indicator of H(2)O(2) production due to polyamine oxidation. The orange-yellow coloured H(2)O(2)-Ti complex was measured at 410 nm in a Shimadzu spectrophotometer. The assay conditions for ...

Analysis methods that require small volumes of aqueous samples can be of large benefit for applications when expensive chemicals are involved or available volumes are substantially small and concentrations are low. A new method is presented to allow microvolume liquid injections on TOC equipment using a special designed Shimadzu gas injection kit in combination with a high precision syringe and...

INTRODUCTION Resperidone chemically 4-[2-[4-(6-fluorobenzo [d] isoxazol-3-yl)-1-piper idyl] ethyl] -3methyl-2, 6diazabicyclo [4.4.0] deca-1, 3-dien-5-one. This drug belongs to a class of Anti-psychotic known as atypical neuroleptics. It is a strong dopamine antagonist. It has high affinity for D2 dopaminergic receptors. It has actions at several 5-HT (serotonin) receptor subtypes. The latter ac...

A simple, rapid, specific and precise reversed-phase high-performance liquid chromatographic method was developed for simultaneous estimation of triacetin, acetic ether, butyl acetate and amorolfine in marketed pharmaceutical liniment. Chromatographic separation was performed on a Shimadzu VP-ODS C(18) column using the mixture of citric acid-hydrochloric acid-sodium hydrate buffer (pH 3.0), ace...

OBJECTIVE Glucose metabolism has not been investigated in human (in vivo) keloids. In the present study, we performed positron emission tomography (PET) with fluorine-18-fluorodeoxyglucose (FDG) to examine glucose metabolism in keloids. MATERIALS AND METHODS Five patients (2 men and 3 women) with typical keloids having a thickness of more than 5 mm were studied. HEADTOME-IV SET-1400W-10 (Shim...
