background uterine leiomyoma (uls) is the most common gynecological tumor and a significant health concern for many women .the interleukin-1 receptor antagonist (il-1ra) is a naturally occurring cytokine inhibiting interleukin- 1 (il-1) activity by binding to the il-1 receptors without signal transduction. objectives the aim of this study was to investigate the association between interleukin-1...

The VNTR loci D7S104, D11S129, D18S17, D20S15, and D21S112 in three indigenous Siberian populations were analyzed to determine the populations' genetic structure. Using the Kolmogorov-Smirnov test, we found that the Siberian indigenous populations of Surinda and Sulamai are separated at the D11S129 locus (p < 0.05). However, the population of Poligus is genetically homogeneous compared with the...

AIM The aim of the work was to assess relationship between gene polymorphism of enzymes influencing dopaminergic-, serotoninergic, and noradrenergic transfer and cognitive functioning of paranoid schizophrenic inpatients (ICD-10). METHOD The following methods have been used in the study: The Test of Everyday Attention (TEA) and The Visual Object and Space Perception Battery (VOSP), psychiatri...

AIM Prodynorphin (PDYN; OMIM: 131340) is the precursor of the dynorphin related peptides which plays an important role in drug abuse. Previous studies have been shown that the expression of PDYN is regulated by a genetic polymorphism of VNTR in the promoter region of the gene. MATERIALS AND METHODS The present case-control study was performed on 52 (41 males, 11 females) methamphetamine depen...

To address conflicting results about the stability of variable number tandem repeat (VNTR) loci and their value in prospective molecular epidemiology of Mycobacterium tuberculosis, we conducted a large prospective population-based analysis of all M. tuberculosis strains in a metropolitan setting. Optimal and reproducible conditions for reliable PCR and fragment analysis, comprising enzymes, den...

The gene encoding NOS-I (NOS1) displays a complex transcriptional regulation, with nine alternative first exons. Exon 1c and 1f are the most abundant forms in the brain. A functional single nucleotide polymorphism (SNP) in exon 1c and a polymorphism in exon 1f, consisting of a variable number of tandem repeats (VNTR) originating short (S) and long (L) alleles, were studied in 184 patients with ...

Our study aimed to associate IL-1β and IL-1RN polymorphisms with AD disease in comparison with elderly control group from São Paulo - Brazil. We genotyped 199 Alzheimer's disease (AD) patients, 165 elderly control and 122 young control samples, concerning VNTR (IL-1RN) and -511C>T and -31T>C (IL-1β) polymorphisms. Our findings revealed that -511C/-31T/2-repetitions VNTR haplotype had a protecti...

Streptococcus pneumoniae remains as an important cause of community-acquired bacterial infections, and the nasopharynx of asymptomatic carriers is the major reservoir of this microorganism. Pneumococcal strains of serotype 14 and serogroup 9 are among the most frequently isolated from both asymptomatic carriers and patients with invasive disease living in Brazil. Internationally disseminated cl...

Various genetic markers have been exploited for fingerprinting the Mycobacterium tuberculosis complex (MTBC) in molecular epidemiological studies, mainly through identifying restriction fragment length polymorphisms (RFLP). In large-scale studies, RFLP typing has practical processing and analysis limitations; therefore, attempts have been made to move towards PCR-based typing techniques. Spolig...

AIM OF THE STUDY Several studies implicated altered inflammatory response in the susceptibility to ovarian cancer, and polymorphisms in inflammatory cytokines were shown to play an important role in the development of malignancies, including ovarian cancer (OC). Here we investigated the relationship between polymorphisms in IL-1β (-511C>T), IL-1RN VNTR, TNF-α (-308G>A), and TNF RII (-322 VNTR) ...
