Enhancing Magnetic Hyperthermia Efficiency in Pd/Fe-Oxide Hybrid Nanoparticles through Mn-Doping.

Multifunctional, biocompatible magnetic materials, such as iron oxide nanoparticles (IONPs), hold great potential for biomedical applications including diagnostics (e.g., MRI) and cancer therapy.

Therapeutic effect of an inhaled levodopa dry powder formulation on off episodes in patients with Parkinson's disease.

Background: Limited treatment options with a rapid onset of action are available to treat off episodes in Parkinson's disease (PD) patients. Therefore, the development of rapid onset formulations, for instance with levodopa, is warranted, which was the reason to investigate an inhalable formulation of levodopa.

Objectives: The primary objective was to determine the duration until maximum effect is reached of inhaled levodopa on the improvement of motor function of PD patients.

Asymmetric Monoreduction of α,β-Dicarbonyls to α-Hydroxy Carbonyls by Ene Reductases.

Ene reductases (EREDs) catalyze asymmetric reduction with exquisite chemo-, stereo-, and regioselectivity. Recent discoveries led to unlocking other types of reactivities toward oxime reduction and reductive C-C bond formation. Exploring nontypical reactions can further expand the biocatalytic knowledgebase, and evidence alludes to yet another variant reaction where flavin mononucleotide (FMN)-bound ERs from the old yellow enzyme family (OYE) have unconventional activity with α,β-dicarbonyl substrates.

The metal cofactor: stationary or mobile?

Metal cofactors are essential for catalysis and enable countless conversions in nature. Interestingly, the metal cofactor is not always static but mobile with movements of more than 4 Å. These movements of the metal can have different functions.
