Nickel ions influence the transepithelial sodium transport in the trachea, intestine and skin.

Measurements of transepithelial potential and resistance in tissue and organ model systems enable the evaluation of the Ni effect on the epithelial sodium channels, aquaporin 3, and the sodium-potassium pump in the epithelial cells. The aim of the presented study was to assess the immediate and prolonged effect of nickel ions on the transport of sodium ions in tissues exposed to direct contact with nickel, including airways, digestive tract and the skin. The influence of 0.

Effect of Low High-Density Lipoprotein Level on Endothelial Activation and Prothrombotic Processes in Coronary Artery Disease-A Pilot Study.

High-density lipoproteins (HDL) play an important role in the prevention of atherosclerosis. The aim of the study was to assess the relationship between serum HDL-C concentration and proinflammatory/prothrombic activation in coronary artery disease (CAD) patients. The study group included 27 acute myocardial infarction (AMI) patients and 30 stable angina pectoris (SA) patients.

Investigation of oxidative stress in patients with alopecia areata by measuring the levels of malondialdehyde and ceruloplasmin in the blood.

Introduction: Alopecia areata (AA) is a chronic, inflammatory and autoimmune disease, presenting with non-scarring hair loss. Although the precise etiopathogenesis of AA remains unknown, oxidative stress is thought to play a role.

Aim: To investigate the role of oxidative stress in AA by measuring the levels of plasma and erythrocyte malondialdehyde (MDA) and the ceruloplasmin (CER) in serum.

Current Research on the Safety of Pyrethroids Used as Insecticides.

Pyrethroids are synthetic derivatives of natural pyrethrins extracted from . They are 2250 times more toxic to insects than to vertebrates due to insects' smaller size, lower body temperature and more sensitive sodium channels. In particular, three pyrethroid compounds, namely deltamethrin, permethrin, and alpha-cypermethrin, are commonly used as insecticides and are recommended for in-home insect control because they are considered to be relatively non-toxic to humans in all stages of life.

Evaluation of Selected Parameters of Lipid Peroxidation and Paraoxonase Activity in Blood of Patients with Joint Osteoarthritis.

Background: Oxidative stress constitutes an important risk factor for tissue/cell damage and is involved in the occurrence and progression of Osteoarthritis (OA).

Objective: The aim of this study was to evaluate the concentration of Malondialdehyde (MDA) in Synovial Fluid (SF) and blood as well as the activity of serum and SF paraoxonase (PON1) of patients with OA. Our study aimed to assess local and systemic responses to oxidative stress.

[S100A4 , MACC - 1 , REG - 4 - promising biomarkers of metastasis in cancers].

Metastasis is one of the key steps in cancer, which is exposed to a large group of patients diagnosed with malignancy. Initiating the process of metastasis is to move the epithelial - mesenchymal cells wherein the cancer cells by blood and lymph vessels, penetrate to distant sites of the body to form secondary foci. Cancer biomarkers are group of molecules (typically proteins) secreted mainly by tumor cells themselves having use in diagnosis of cancer, determining the length of survival in patients or in the assessment of the body's response to treatment.
