Assessment of the Potential Health Risk of Gold Nanoparticles Used in Nanomedicine.

Due to unique properties, nanoparticles (NPs) have become a preferred material in biomedicine. The benefits of their use are indisputable, but their safety and potential toxicity are becoming more and more important. Especially, excessive production of reactive oxygen species (ROS) induced by the strong oxidation potential of metal NPs could evoke adverse effects associated with damage to nucleic acids, proteins and lipids.

Cholesterol level correlate with disability score in patients with relapsing-remitting form of multiple sclerosis.

Background: Multiple sclerosis (MS) is an autoimmune disease characterised by demyelination. There are many environmental factors that can affect the progression of this disease. It is necessary to better understand the impact of these factors in MS pathogenesis and progression.

Impact of glycemic control on advanced glycation and inflammation in overweight and obese patients with type 2 diabetes mellitus.

Aim: In this study we tried to investigate the impact of glycemic control on parameters of glycation and inflammation in overweight and obese patients with type 2 diabetes mellitus.

Patients And Methods: Markers of glycation (HbA1c, AGEs; measured by HPLC and spectrofluorimetry, resp.) and inflammatory markers (IL-6, IL-8, TNF-α, MCP-1; measured by xMAP technology) were assessed in 69 patients with T2DM, of whom 32 were patients were with poor glycemic control (PGC group), 37 patients were with good glycemic control (GGC group) and 23 were healthy blood volunteers.

Multiple sclerosis: evaluation of purine nucleotide metabolism in central nervous system in association with serum levels of selected fat-soluble antioxidants.

In the pathogenesis of demyelinating diseases including multiple sclerosis (MS) an important role is played by oxidative stress. Increased energy requirements during remyelination of axons and mitochondria failure is one of the causes of axonal degeneration and disability in MS. In this context, we analyzed to what extent the increase in purine catabolism is associated with selected blood lipophilic antioxidants and if there is any association with alterations in serum levels of coenzyme Q10.

Influence of some mineral ions on lipid peroxidation in vitro.

Recently, a growing interest has been recorded in mineral content of mammalian diet, which might impair their development. Focused on the topic, we studied the effect of Al3+, Si4+, Sr2+ and Na2S on the intensity of malondialdehyde (MDA) production in vitro. MDA, as one of oxidative stress markers, was determined in rat brain homogenates in the conditions of lipid peroxidation (LP) activated by iron ions and ascorbate.
