The Effects of Fisetin and Curcumin on Oxidative Damage Caused by Transition Metals in Neurodegenerative Diseases.

Neurodegenerative diseases pose a significant health challenge for the elderly. The escalating presence of toxic metals and chemicals in the environment is a potential contributor to central nervous system dysfunction and the onset of neurodegenerative conditions. Transition metals play a crucial role in various pathophysiological mechanisms associated with prevalent neurodegenerative diseases such as Alzheimer's and Parkinson's.

Berberine: Pharmacological Features in Health, Disease and Aging.

Background: Berberine is the main active compound of different herbs and is defined as an isoquinoline quaternary botanical alkaloid found in barks and roots of numerous plants. It exhibits a wide range of pharmacological effects, such as anti-obesity and antidiabetic effects. Berberine has antibacterial activity against a variety of microbiota, including many bacterial species, protozoa, plasmodia, fungi, and trypanosomes.

Changes in the antioxidant system and level of proinflammatory cytokin IL-1beta in the blood patients of sufferi.

Diabetes mellitus type 1 provokes the development of the oxidative stress, accompanied by the increased level of TBA-active products, activation of NO-synthases and increased production of nitric oxide. Activation of glutathione reductase, decrease of the glutathione peroxidase and superoxide dismutases activity was observed. This shows a specific disturbance in the functioning of the antioxidant defense system and the augmentation in the concentration of one of the major first line reacting cytokin (IL-1beta).

[The changes of oxidative-reductive processes and fatty acid composition of liver lipids in rats with streptozotocin-induced diabetes].

The processes of lipid peroxidation, oxidative modification of proteins, the state of antioxidant protection system enzymes and fatty acid composition of liver lipids were investigated in rats with streptosotocin-induced diabetes. The development of diabetes is accompanied by oxidative stress, which results in the activation of lipid peroxidation processes and the increase in the amount of nitrogen oxide and the activity of antioxidant protection system enzymes. The increase of the amount of saturated fatty acid and fall in the amount of unsaturated fatty acid has been detected.
