Mitochondrial Dynamics in Brain Cells During Normal and Pathological Aging.

Mitochondrial dynamics significantly play a major role in the pathogenesis of neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease. The dysregulation of mitochondrial biogenesis and function, characterized by impaired fission and fusion processes mediated by a number of proteins, in particular, Drp1, Mfn1, Mfn2, Opa1, and PGC-1α, contributes to neuronal vulnerability and degeneration. Insufficient mitophagy and disrupted mitochondrial transport exacerbate oxidative stress and neurotoxicity.

Accumulation of Anthocyanin in the Aleurone of Barley Grains by Targeted Restoration of the Gene.

Blue barley grain pigmentation results from anthocyanin accumulation in the aleurone layer. Anthocyanins are known for their beneficial effects on human health. The gene encoding the MYELOCYTOMATOSIS 2 (MYC2) transcription factor is potentially responsible for the blue coloration of the aleurone.

Interleukin-1 Blockade With RPH-104 (Goflikicept) in Patients With ST-Segment Elevation Myocardial Infarction: Secondary End Points From an International, Double-Blind, Randomized, Placebo-Controlled, Phase 2a Study.

In a randomized double-blinded clinical trial of patients with ST segment elevation myocardial infarction (STEMI), goflikicept, an interleukin-1 blocker, significantly reduced systemic inflammation, measured as the area under the curve (AUC) for high-sensitivity C reactive protein at 14 days. We report secondary analyses of biomarkers at 28 days, and cardiac function and clinical end points at 1 year. Patients received a single administration of goflikicept 80 mg (n = 34), goflikicept 160 mg (n = 34), or placebo (n = 34).

Kainate-Induced Reorganization the Dentate Gyrus of the Hippocampus Is Accompanied by Activation of Mitochondrial Fission in the Granular Layer Neurons.

The reorganization of the dentate gyrus of the hippocampus and changes in mitochondrial fission were evaluated using the kainate model of temporal lobe epilepsy. In 28 days after administration of 0.5 μg kainic acid, disturbances in the distribution of neuronal precursors in the subgranular zone of the hippocampus, thickening of the granular layer, and an increase in the content of synaptophysin in the molecular layer were detected.

Extended investigation of the conductive characteristics of monoclinic tungstates with a BiWO ( = La, Pr or Nd) composition.

δ-BiO-based materials have long been a focus of interest as potential solid oxide fuel cell materials due to their high electrical conductivity. Here, extensive studies of thermal stability, polymorphism and conductivity have been carried out for the first time on BiWO ( = La, Pr or Nd) compounds in the ternary BiO-O-WO system, mentioned more than 20 years ago by Watanabe. The obtained single-phase materials were found to be sufficiently dense (more than 94%) and thermally stable (up to 900 °C).
