Controlling both UV and visible emissions in ZnO quantum dots (QDs) poses a significant challenge due to the inherent introduction of defects during the growth process. We have refined the photoluminescence (PL) emission characteristics of ZnO QDs through a single-step, reagent-free femtosecond pulsed laser ablation in liquid (fs-PLAL) technique. The ratio of the near band edge (NBE) to deep-level emission (DLE), which determines the shape of the QDs' optical emission spectrum, is precisely controlled by the ablation laser pulse parameters-namely, pulse energy and temporal duration.

Rationale: Neuronal ceroid lipofuscinoses (NCLs) are rare, fatal, inherited neurodegenerative disorders characterized by myoclonic epilepsy, cognitive decline, brain atrophy, and retinopathy. The pathogenesis and clinical manifestations of NCL are not well understood and frequently result in misdiagnosis and overtreatment. The aim of this case report and review is to improve our understanding of the clinical features and management of NCL.

In this study, Phylloporia fontanesiae polysaccharide was successfully isolated through a sequential water extraction and alcohol precipitation process. Utilizing the Box-Behnken design, the extraction process was optimized based on single-factor experiments, considering variables such as the material-to-liquid ratio, extraction temperature, extraction time, and the number of extractions. The polysaccharide composition of P.

The establishment of Russian neurology in the late 19th century was significantly shaped by the neurology department at La Salpêtrière Hospital under Professor Jean-Martin Charcot's leadership. A group of Russian neurologists, guided by Professor Kozhevnikov and featuring his disciples such as Korsakov, Minor, Darkshevich, and Bekhterev, had the privilege of being mentored by Professor Charcot. Subsequently, they played pivotal roles in founding various neurology services in Russia, greatly influenced by the teachings and insights they acquired under Charcot's tutelage.
