Carcinogenesis may result from abnormal methylation of cancer-related genes regulatory sequence. Though, the polymorphic variants of genes encoding enzymes of folate and methionine metabolism may have an effect on DNA methylation. Using PCR-RFLPs, we examined the polymorphism distribution of genes encoding methionine synthase (MTR);(More)
The contribution of the CCL2 −2518 A>G (rs 1024611) polymorphism in the occurrence and progression of various cancers has been found to be discordant. We studied the prevalence of the CCL2 −2518 A>G polymorphism in patients with breast cancer (n = 160) and controls (n = 323) in a sample of the Polish population. There were no significant differences in CCL2(More)
We examined the distribution of the CCND1 A870G (rs9344) polymorphic variant in patients with cervical cancer (n = 129) and healthy individuals (n = 288) in a sample of a Polish cohort. We showed that patients with advanced cervical cancer bearing the CCND1 A/A and A/G genotypes displayed a 1.811-fold increased risk of cervical cancer (95% CI = 1.150–2.852,(More)
We analyzed protein kinase R (PKR)-binding domain sequences of hepatitis C virus (HCV) NS5A protein and the profile of HCV-specific antibodies from pretreatment sera of HCV-chronically infected patients. Results were compared with clinical data to verify their influence on the course and result of therapy. Of 9 patients enrolled in a 12-month treatment with(More)
OBJECTIVES A role of non-thrombotic iliac vein lesions (NIVLs) in the development of primary varicose veins (PVVs) has not been studied. It seems that intravascular ultrasound (IVUS) is the most accurate method to diagnose these lesions. The aim of the study was to investigate the association between the presence of NIVLs and PVVs and the frequency of NIVLs(More)
BACKGROUND The purpose of this study was to establish the safety of negative pressure wound therapy (NPWT) in the treatment of acutely debrided, deep diabetic foot infections (DDFI) and to determine the value of inflammatory markers in monitoring of treatment of these infections with negative pressure wound therapy. METHODS A group of ten patients with(More)
The SDF1-3’ G801A (rs 1801157) polymorphism is associated with increased risk of various types of cancers, including those of the neck and head. Using PCR-RFLPs, we investigated the distribution of SDF1-3′ G801A genotypes in patients with laryngeal cancer (n = 118) and controls (n = 250) in Poland. We found that patients with SDF1-3’ A/A and G/A genotypes(More)
The CXCL12-3' G801A transition (rs1801157) has been associated with the incidence of breast cancer. However, the contribution of CXCL12-3' G801A polymorphisms in breast cancer development and progression has been controversial. Therefore, we examined the incidence of CXCL12-3' G801A polymorphic variants in patients with breast cancer (n = 193) and controls(More)
BACKGROUND To compare the level of difficulty of four techniques of endovenous thermal ablation (EVTA) of the great saphenous vein and the echogenicity of the tip of the working device in vivo. METHODS Sixty patients qualified to the EVTA of the great saphenous vein were randomly assigned to treatment with an 810-nm axial diode laser [endovenous laser(More)
Peripheral arterial disease (PAD), caused by atherosclerotic processes, is allied with an increased risk of ischemic events, limb loss, and death. Recently, the use of a solid-state laser at 355 nm within a hybrid catheter was suggested for that purpose. In this work, short nanosecond pulses of a solid-state laser at 355 nm delivered through a hybrid(More)
