Parkinson disease (PD) is the common neurodegenerative disease. α-Synuclein (ASN), main aggregating protein in neural cells of CNS in PD, was found in peripheral fluids. Testing ASN in plasma is potential test for diagnose PD, but previous studies are controversial. The aim of this study was to investigate if plasma ASN level may be a valuable biomarker, is the level of plasma ASN concentration different in various motor subtypes of diseases, is there a relation between the level of plasma ASN and the severity of motor symptoms. Patients with PD hospitalized in Neurology Department, Medical College were performed sequencing the 8th and 9th exon of GBA gene. Next plasma ASN level was tested in 58 patients with sequenced GBA gene and in 38 healthy volunteers (HV), matched by the age (respectively 68.43 vs. 64.57 years of age) and sex (female %, respectively: 43.10 vs.44.74). Patients were assessed with the scales: UPDRS (II, III, IV), Hoehn-Yahr (HY) and qualified to PIGD or TD subtype. For homogeneity of the group patients with GBA mutation were excluded from the analysis. The ASN level did not differ between patients and HV (respectively: 4.53 vs. 3.73ng/ml) and between patients with different subtypes. There was inverse correlation between ASN and HY in PIGD subtype. Plasma ASN level is not valuable marker of the disease. It does not differ in subtypes of the disease. There is relation between plasma ASN level and the severity of the disease in PIGD subtype.

Uterine myomas represent one of the most frequently manifested benign tumors in women. They originate from smooth muscle cells of myometrium or its blood vessels. Many studies suggest that inflammation and pro-inflammatory factors may play a role in the carcinogenesis with an involvement of the transcription factor NF-kappaB which activity can be controlled by various environmental factors, including many cytokines. The aim of the study was to investigate the expression of NF-B, interleukin-1β (IL-1β), tumor necrosis factor a (TNF-α), cyclooxygenase 2 (COX-2) and inducible nitric oxide synthase (iNOS) in myometrium and uterine myomas of women of various age. The expression of NF-kappaB, selected cytokines and enzymes was estimated in women of reproductive or perimenopausal age by semiquantitative immunohistochemistry. The expression of the examined proteins was higher in myomas than in control myometrium and was dependent on the size of myomas and the age of women. However, the expression of the cytoplasmic NF-kappaB observed in uterine myomas was independent on the size of myomas and no significant differences were observed in the number of stained nuclei between control and myoma groups. Thus, the expression of proinflammatory factors in myomas was not accompanied by the nuclear activation of NF-kappaB p65. The results of our study indicate that the examined factors may be involved in the pathogenesis of benign tumors and not only malignant diseases.

Background: It has been proved that nuclear factor-kappa B (NF-κB) is activated in all cells, promotes proliferation of cells, regulates the immunological and inflammatory response, and contribute to the pathogenesis of many conditions, including cancer. Many studies pointed to constitutive activation of NF-κB in cells of certain malignant tumors. Objective: The aim of the study was to analyze the role of nuclear growth factor κB as colon cancer marker and prognostic factor. Materials and Methods: The study included 59 primary colorectal tumor patients and 15 patients in control group. The tumor samples were taken during partial colectomy and colonoscopy in control group. Tissues samples were fixed and embedded in paraffin blocks and cut. Sections were used for schedule immunohistochemical staining with the application of specific antibody for NF-κB epitope. The marker expression was compared with well-known prognostic factors in colon tumors such as tumor type, stage, and grade to establish if it might be a potential prognostic factor. Results: The results showed statistically significant difference between control group and cancer group. Conclusions: The expression NF-κB did not depend on the stage and grade of colon tumors.
