Protective Role of Histidine Supplementation Against Oxidative Stress Damage in the Management of Anemia of Chronic Kidney Disease

Pharmaceuticals, 2018
Anemia is a major health condition associated with chronic kidney disease (CKD). A key underlying cause of this disorder is iron deficiency. Although intravenous iron treatment can be beneficial in correcting CKD-associated anemia, surplus iron can be ...

Natural Design of a Stabilized Cross‐β Fold: Structure of the FuA FapC from Pseudomonas Sp. UK4 Reveals a Critical Role for Stacking of Imperfect Repeats

Advanced Materials, EarlyView.
We report a 3.2 Å cryoEM structure of functional amyloid protein FapC from Pseudomonas sp. UK4, an essential component of bacterial biofilm, which reveals a Greek key‐shaped protofilament, supports bioinformatically determined motifs, nuances AlphaFold predictions, emphasizes heterogeneous cross‐β stacking in amyloid cross‐seeding and shows strain ...

Milk production and efficiency of utilization of nitrogen, metabolizable protein, and amino acids are affected by protein and energy supplies in dairy cows fed alfalfa-based diets

Journal of Dairy Science, 2022
: Alfalfa has a lower fiber digestibility and a greater concentration of degradable protein than grasses. Dairy cows could benefit from an increased digestibility of alfalfa fibers, or from a better match between nitrogen and energy supplies in the rumen.

One‐Pot Single‐Step Approach for the Controlled Synthesis of Multifunctional Microparticles

Advanced Materials, EarlyView.
A versatile one‐pot strategy combines bipolar electrochemistry and the water‐organic interface to synthesize in a single‐step complex patchy particles, which cannot be achieved by any other deposition process. Under the influence of an electric field, microparticles undergo selective surface modification via coupled redox reactions, enabling ...

Fluorescence Label‐Free Doxorubicin Sensor Using Polystyrene Sulfonate as a Synthetic Receptor in Whispering Gallery Mode Microresonators

Advanced Sensor Research, EarlyView.
The illustration showcases resonant optical microsensors for Doxorubicin (DXR) detection, using polystyrene sulfonate (PSS) as a synthetic receptor. PSS is deposited as a nanometer‐thick layer on fluorescent microparticles via layer‐by‐layer assembly. DXR‐PSS interaction is depicted, highlighting its effect on the sensor's resonant modes.
