This reduction in the ICR was attributed to the precipitated silver nanoparticles in the implanted layer as well as a noticeable reduction in the passive layer thickness and increased amounts of highly conducive metallic silver and nickel. All tests showed higher chemical stability of such plates in accelerated cathode environments containing 0. The superiority of Ni-coated plates is attributed to the reduction in the thickness of the passive layer caused by the Ni implantation.
It might be one Thesis on polypyrrole the toxic sensitizer and irritant on the skin, and initiator of lung diseases, so it is important to understand the characterization and toxic mechanism of MI in the body. In the pharmacokinetic study using rats, presented analysis method was useful for detecting the profile of MI in the plasma.
We determined half-life, clearance and distribution of MI by WinNonlin software and these might be useful information for the study on the toxicokinetics in body.
In spite of the introduction of new agents such as L-LAAM and buprenorphine, methadone continues to be the drug of choice for the treatment of heroin addiction. Due to the wide variation in half-life among individuals reported values hoursthere is a significant ovedose risk.
Together with the requirement for effective monitoring of replacement therapy, it emphasizes the need for development of fast, precise and reliable analytical method for quantification of methadone in biological samples.
In this research, liquid chromatography-mass spectrometry LC-MS method for determination of methadone in blood was developed, using solid-phase SPE extraction for the preparation of samples.
The chromatographic separation was performed on XTerra MS C18 column, using a mixture of formic buffer pH 3,5 — acetonitrile Linearity was achieved in the range from 0. Retention time of methadone Thesis on polypyrrole 5.
Limit of detection and limit of quantification were 1. The intra-assay precisions RSD were about 0. The inter-assay precisions RSD were 0.
The accuracy varied from Described LC-MS method for analysis of methadone in blood is precise, accurate, reproducible and reliable, with significantly shortened time of analysis run time 10 min.
Due to low therapeutic index of carbamazepine, there is a need for routine measuring its concentrations in serum. Monitoring of the drug level helps to adjust the dose and achieve optimal therapeutic effects while avoiding subtherapeutic and toxic level.
The aim of this study was to determine serum concentration of carbamazepine in patients with epilepsy who are on monotherapy, as well as to show the correlation of different methods on different systems for determination of the drug in serum spectrophotometric and chromatographic method.
For the study were used serums of the patients with epilepsy, 35 serums total.
Concentration of carbamazepine in serum, in the interval of reference values had Our results show that the most of patients on carbamazepine therapy have the correct dosage regimen. The statistical difference between different systems and methods is not significant.
There is a strong correlation and connection, so the photometric method is reliable and applicable for routine operation. Box3Institute of general and physical chemistry, P.

Determination of urinary metabolite profile provides novel information on phenotypic characteristics of an organism that cannot be obtained from target measurement.
After data processing of raw GC-MS data crucial step is to identify compounds of interest. Due to the complexity of the matrix, wide chemical diversity of the metabolites and their wide concentration range, metabolite identification is intrinsically difficult.
A Kovats retention index system uses a series of standards, homologous series of n-alkanes applied as reference peak. Despite some limitations, presented methods could be very useful in VOMs identification.
To confirm identification of unknown VOMs unequivocally, analysis of available analytical standards using the same GC-MS conditions is recommended. They have different chemical structures from tetrahydrocannabinol THC but similar effects on endocannabinoid receptors.
Their popularity is continuously increasing. Inthe emergence of this cannabinoid was reported by two countries, the USA and Cyprus. It is declared as a freshener with a warning that it is not for human use. A sample of plant material was prepared by extraction with methanol in the ultrasonic bath for 30 min.
The resulting mass spectrum did not give an appropriate match with the base of the spectrum used at that moment in the laboratory.
