Article Synopsis
- - This study investigates how synthesis temperature affects the properties of colloidal cadmium telluride (CdTe) nanoplatelets (NPLs), which are useful for applications like solar cells and LEDs.
- - CdTe NPLs were created at various temperatures (170 °C to 200 °C) and analyzed using techniques like UV-Vis absorption and electron microscopy to evaluate their structure and elemental makeup.
- - The results indicated that the best quality NPLs, in terms of stoichiometry and optical properties, were obtained at 190 °C, showing significant changes in crystal structure and luminescence based on temperature variations.
Colloidal quasi-two-dimensional cadmium chalcogenide nanoplatelets have attracted considerable interest due to their narrow excitonic emission and absorption bands, making them promising candidates for advanced optical applications. In this study, the synthesis of quasi-two-dimensional CdSe NPLs with a thickness of 3.5 monolayers was investigated to understand the effects of synthesis temperature on their stoichiometry, morphology, and optical properties.

- * The study used a modified cell line containing the m.15059G>A mutation to assess the impacts of eliminating this mutation on mitochondrial function.
- * Results showed that removing the m.15059G>A mutation enhanced mitochondrial membrane potential and efficiency, reduced harmful byproducts, and did not alter the antioxidant system, indicating the mutation's negative role in mitochondrial health.
Article Synopsis
- Mitochondria play a crucial role in energy production, and recent findings link certain mutations in mitochondrial DNA (mtDNA) to the development of atherosclerosis, a chronic disease affecting arteries.
- This study aimed to investigate the relationship between oxygen consumption in cells and these atherosclerosis-related mtDNA mutations to better understand their role in disease progression.
- Results showed that specific mtDNA mutations are associated with reduced cellular respiration, indicating they could potentially contribute to the mechanisms of atherosclerosis and suggest new targets for treatment.
Energy substrate supplementation increases ATP levels and is protective to PD neurons.

Alteration of mitochondrial metabolism by various mutations or toxins leads to various neurological conditions. Age-related changes in energy metabolism could also play the role of a trigger for neurodegenerative disorders. Nonetheless, it is not clear if restoration of ATP production or supplementation of brain cells with substrates for energy production could be neuroprotective.
