Perspective targeted diagnosis and therapy of mitochondrial bioenergetics across different diagnoses.

Important metabolic variables that lead to the development of many diseases, including "mitochondrial diseases," include increased oxidative stress and mitochondrial malfunction. Given that the clinical picture and metabolic alterations in individuals suspected of having mitochondrial illnesses lack distinct characteristics, the development of sensitive and specific diagnostic techniques to detect alterations in mitochondrial bioenergetics is imperative. High-resolution respirometry (HRR), is a minimally invasive technique that enables the analysis of mitochondrial function in platelets taken from peripheral blood.

Astaxanthin, Compared to Other Carotenoids, Increases the Efficacy of Methotrexate in Rat Adjuvant Arthritis.

This in vivo study performed in rat adjuvant arthritis aims to advance the understanding of astaxanthin's therapeutic properties for the possible treatment of rheumatoid arthritis (RA) in monotherapy and along with the standard RA treatment, methotrexate (MTX), in combination therapy. The main goal was to elucidate astaxanthin's full therapeutic potential, evaluate its dose dependency, and compare its effects in monotherapy with other carotenoids such as β-carotene and β-cryptoxanthin (KXAN). Moreover, potential differences in therapeutic activity caused by using different sources of astaxanthin, synthetic (ASYN) versus isolated from (ASTAP), were evaluated using one-way ANOVA (Tukey-Kramer post hoc test).

A New Strategy for Effective Succinic Acid Production by sp. LU1 Using a Medium Based on Crude Glycerol and Whey Permeate.

The newly-isolated strain sp. LU1, which has previously been shown to be an effective producer of succinic acid on glycerol with the addition of lactose, was used for further intensive works aimed at improving the production parameters of the said process. The introduction of an initial stage of gentle culture aeration allowed almost 47 g/L of succinic acid to be obtained after 168 h of incubation, which is almost two times faster than the time previously taken to obtain this amount.

Organic Zinc Salts as Pro-Ecological Activators for Sulfur Vulcanization of Styrene-Butadiene Rubber.

Organic zinc salts and complexes were applied as activators for sulfur vulcanization of styrene-butadiene elastomer (SBR) in order to reduce the content of zinc ions in rubber compounds as compared with conventionally used zinc oxide. In this article, the effects of different organic zinc activators on the curing characteristics, crosslink densities, and mechanical properties of SBR as well as the aging resistance and thermal behavior of vulcanizates are discussed. Organic zinc salts seem to be good substitutes for zinc oxide as activators for sulfur vulcanization of SBR rubber, without detrimental effects to the vulcanization time and temperature.

A new insight into the molecular hydrogen effect on coenzyme Q and mitochondrial function of rats.

Mitochondria are the major source of cellular energy metabolism. In the cardiac cells, mitochondria produce by way of the oxidative phosphorylation more than 90% of the energy supply in the form of ATP, which is utilized in many ATP-dependent processes, like cycling of the contractile proteins or maintaining ion gradients. Reactive oxygen species (ROS) are by-products of cellular metabolism and their levels are controlled by intracellular antioxidant systems.
