Influence of NG-nitro-L-arginine methyl ester on clinical and biochemical effects of methylene blue in pentylenetetrazole-evoked convulsions [PDF]

open access: yesVojnosanitetski Pregled, 2012
Background/Aim. Despite years of research in a number of experimental models the question whether nitric oxide (NO) and methylene blue (MB) have pro- or anticonvulsant effects remains to be fully resolved. Methods.

Photoprotective role of NADPH:protochlorophyllide oxidoreductase A [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
A homology model of NADPH:protochlorophyllide (Pchlide) oxidoreductase A (POR; E.C. 1.3.33.1) of barley is developed and verified by site-directed mutagenesis. PORA is considered a globular protein consisting of nine α-helices and seven β-strands.

Bioinspired Design of Heterogenous Single‐Atomic‐Site Catalysts for Electrocatalysis and Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review gives a summary on the representative bioinspired single‐atomic‐site catalysts (SACs) and their applications in heterogeneous electrocatalysis and photocatalysis. The fundamentals of bioinspired design strategies are systematically discussed in the context of the first shell coordination, the second/long‐range coordination, and the outer ...

Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

open access: yesAdvanced Materials, EarlyView.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Integrating Visible‐Light Photocatalysis and Enzymes for the Stereoselective Synthesis of Alcohols and Amines

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
The integration between visible‐light photocatalysis and biocatalysis has the potential to greatly improve modern organic synthesis by combining the production of valuable synthetic intermediates under mild photochemical conditions with the high degree of stereoselectivity reached by enzymes. The review collects the recent efforts in the photoenzymatic

Cost‐Effective Hierarchical Cobalt Nanostructured Laser‐Induced Graphene for Enhanced Uric Acid Detection

open access: yesAdvanced Sensor Research, EarlyView.
A one‐step electrochemical strategy is utilized to develop a flexible, enzyme‐free biosensor for the sensitive detection of uric acid (UA). The hierarchical cobalt nanostructures synergistically enhance the performance of the biosensor, resulting in a broad detection range of 5 to 700 µM with a sensitivity of 6.75 µA µM−1 cm−2 and a low detection limit

Immobilization as a Strategy for Improving Enzyme Properties-Application to Oxidoreductases

open access: yesMolecules, 2014
The main objective of the immobilization of enzymes is to enhance the economics of biocatalytic processes. Immobilization allows one to re-use the enzyme for an extended period of time and enables easier separation of the catalyst from the product ...

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

open access: yesAdvanced Science, EarlyView.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...
