Altered mitochondria-associated ER membrane (MAM) function shifts mitochondrial metabolism in amyotrophic lateral sclerosis (ALS).

Mitochondrial function is modulated by its interaction with the endoplasmic reticulum (ER). Recent research indicates that these contacts are disrupted in familial models of amyotrophic lateral sclerosis (ALS). We report here that this impairment in the crosstalk between mitochondria and the ER impedes the use of glucose-derived pyruvate as mitochondrial fuel, causing a shift to fatty acids to sustain energy production.

Effect of 2-Aminoethoxydiphenyl Borate on the State of Skeletal Muscles in Dystrophin-Deficient Mice.

Objective: Ca overload of muscle fibers is one of the factors that secondarily aggravate the development of Duchenne muscular dystrophy (DMD). The purpose of this study is to evaluate the effects of the Ca channel modulator 2-aminoethoxydiphenyl borate (APB) on skeletal muscle pathology in dystrophin-deficient mice.

Methods: Mice were randomly divided into six groups: wild type (WT), WT+3 mg/kg APB, WT+10 mg/kg APB, , +3 mg/kg APB, +10 mg/kg APB.

[Recommendations for the rehabilitation of patients with chronic kidney disease requiring hemodialysis (literature review)].

Unlabelled: Chronic kidney disease (CKD) is a global health problem, CKD is widespread in the world, on average it is detected in 10-13% of the adult population. Sedentary patients with CKD on dialysis have a higher risk of mortality. Despite the significant association of physical function with mortality in patients with CKD, physical function is not routinely assessed and exercise is not a component of the routine management of patients with CKD on dialysis.

Novel Mixed-Matrix Pervaporation Membrane Based on Polyether Block Amide Modified with Ho-Based Metal-Organic Framework.

Segmented polymers, such as polyether block amide (PEBA), exhibit unique properties due to the combination of different segments. PEBA consists of soft polyester and rigid polyamide blocks, enabling its use in various industrial applications, including membrane technologies. In this study, PEBA membranes modified with a holmium-based metal-organic framework (Ho-1,3,5-Hbtc) were developed for enhanced pervaporation separation of water/isopropanol and water/phenol mixtures.

Application of a modified lactate dehydrogenase assay to evaluate the viability of cells cultured on 3D scaffolds when commonly used assays fail.

The development of new compounds or materials for medicine suggests a study of their cytotoxicity. The effect of a material on cell viability can be evaluated by several methods based on DNA content, DNA synthesis, plasma membrane integrity, cellular enzyme activity, cellular reducing potential, and ATP level. Sometimes it is impossible to apply widely used commercially available reagents, e.
