Oral administration of flavonoid-containing preparation Extralife (daily dose 40 mg/kg) to animals with modeled Parkinson's syndrome considerably improved their survival and the main diagnostic and nosological parameters characterizing the state of locomotor functions. The preparation decreased animal mortality, rigidity, disturbances in dynamic muscular work and coordination of movements, and reduced oligokinesia. Experimental data confirm the involvement of mitochondrial enzyme complex I dysfunction in the pathogenesis of the disease and showed the possibility of by-passing this site of the respiratory chain with Extralife.

Article Synopsis
- Flavonoids are natural substances that can help protect our bodies with benefits like fighting off bad chemicals, reducing inflammation, and even stopping tumors.
- Scientists are testing supplements with flavonoids to see if they can help prevent or treat different diseases, but they face challenges because our bodies don't always absorb them well.
- The review talks about how flavonoids are categorized and where they come from, shares what research has been done on flavonoid supplements, and discusses new ways to help our bodies use flavonoids better so they can be more effective in medicine.
Antitumor Effects of Microencapsulated Extract on Breast Carcinoma and Human Cervical Cancer Cells In Vitro.

Flavonoid-containing extract has been studied in relation to breast carcinoma and human cervical cancer cells in encapsulated and native form. Encapsulation was realized in polymer shells, which were formed by the layer-by-layer method using sequential adsorption of poly(allylamine hydrochloride) and poly(sodium 4-styrenesulfonate) on the destructible cores. The extract was prepared by the author's method and characterized using high performance liquid chromatography.

Luteolin (LTL) is a flavonoid containing a -diol, which has significant anti-inflammatory, anti-allergic, anti-diabetic, anti-cancer and neuroprotective activities. In this work, a silver modified boric acid affinity polyvinyl imine (PEI) dendritic adsorbent (PPEI-Ag@CPBA) was prepared on polystyrene (PS) for the rapid recognition and selective separation of LTL. A thin layer of polydopamine (PDA) was formed on the surface of the substrate by self-polymerization, and a PDA-coated PS material (PS@PDA) was obtained.

Wound healing in horses is complicated by the excessive growth of granulation tissue, commonly known as proud flesh and is similar to keloids in human beings. At present, there is no satisfactory treatment for proud flesh in horses. In this study, we, for the first time, demonstrated that leaf extract of Aerva javanica suppresses excessive growth of granulation tissue in horses.

Background: Phytotherapy is an important therapeutic option in functional gastrointestinal diseases (FGID). It has a large tradition, with different approaches in different regions of the world, some of which have made their way into modern evidence-based medicine (EBM).
Summary: Taking into account the number of herbs in use, and also the cumulated scientific evidence on them, FGID are possibly the most important indication in phytotherapy.
