HLA profile of the Macedonian, Albanian and Macedonian Muslim donors in the Macedonian Bone Marrow Donor Registry.

The aim of this study was to determine the HLA allele and haplotype frequencies of the volunteer donors from the Macedonian Bone Marrow Donor Registry (MBMDR). We analyzed 1541 donors, from different nationalities and presented the HLA allele and haplotype frequencies for Macedonian, Albanian and Macedonian Muslims, most numerous nationalities in MBMDR. Difference between the three groups was observed for allele frequencies in HLA-C and HLA-DRB1 loci.

HLA profile of the donors in the Macedonian Bone Marrow Donor Registry.

The importance of HLA alleles in the process of haematopoietic stem cell transplantation, especially the process of unrelated donor search, is enormous. Macedonian Bone Marrow Donor Registry was established in 2010 and has registered volunteer donors from different nationalities that live in the Republic of Macedonia. The aim of this study was to determine the HLA allele and haplotype frequencies of the volunteer donors from the Macedonian Bone Marrow Donor Registry and to compare this results with the Macedonians from a family study.

Association of cytokine gene polymorphisms with chronic obstructive pulmonary disease in Macedonians.

The aim of this study was to examine the association of 22 cytokine gene polymorphism in Macedonians with chronic obstructive pulmonary disease (COPD). The sample of the population comprised of 301 normal respondents and 62 patients with COPD. Cytokine genotyping was performed by polymerase chain reaction with sequence-specific priming (PCR-SSP).

Development of an HPLC method for the determination of nifedipine in human plasma by solid-phase extraction.

Nifedipine, a dihydropyridine calcium channel antagonist, is widely used in the treatment of hypertension and other cardiovascular disorders. A selective, sensitive and accurate high-performance liquid chromatographic method has been developed, validated and applied for determination of nifedipine in human plasma samples. A series of studies were conducted in order to investigate the effects of mobile phase composition, buffer concentration, mobile phase pH and concentration of organic modifiers, and to develop a convenient and easy-to-use method for quantitative analysis of nifedipine.
