d‐Allulose can be produced from d‐fructose by d‐allulose 3‐epimerase. Based on sequence homology information, we successfully engineered thermostable mutants with the protein engineering method. By integrating positive mutations, we constructed an enzyme that exhibits hyperthermostability without a loss in the activity.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Electric-field-enhanced transport in polyacrylamide hydrogel nano-composites [PDF]
Electroosmotic pumping through uncharged hydrogels can be achieved by embedding the polymer network with charged colloidal inclusions. Matos and co-workers (2006) recently used the concept to enhance the diffusion-limited flux of uncharged molecules across polyacrylamide hydrogel membraness for the purpose of improving the performance of biosensors ...

Biologic activity in a fragment of recombinant human interferon α [PDF]
To attempt to locate functionally important regions of the interferon (IFN) molecule, recombinant human IFN-α2 was subjected to proteolytic digestion. The bacterial proteinase thermolysin produced two major complementary fragments, HuIFN-α2-(1-110) and ...

GEN1 from a thermophilic fungus is functionally closely similar to non-eukaryotic junction-resolving enzymes [PDF]
Processing of Holliday junctions is essential in recombination. We have identified the gene for the junction-resolving enzyme GEN1 from the thermophilic fungus Chaetomium thermophilum and expressed the N-terminal 487-amino-acid section.

Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular

Electroblotting onto activated glass. High efficiency preparation of proteins from analytical sodium dodecyl sulfate-polyacrylamide gels for direct sequence analysis [PDF]
We have developed a new method for the isolation of proteins for microsequencing. It consists of electrophoretic transfer (electroblotting) of proteins or their cleavage fragments onto activated glass filter paper sheets immediately after separation by ...

Modulation of apoprotein E secretion in response to receptor-mediated endocytosis in resident and inflammatory macrophages. [PDF]
We have determined the effect of various endocytic ligands on the secretion of ApoE by macrophages. ApoE was a major secreted protein of resident macrophages, but BCG-activated macrophages secreted little ApoE and periodate-elicited macrophages secreted ...

Key Trends and Insights in Smart Polymeric Skin Wearable Patches
Intelligent polymers, which respond to various physical and biological stimuli, are explored for the development of skin wearable patches in biomedical applications. Smart polymers, also known as intelligent or stimuli‐responsive polymers, play a crucial role in the development of advanced wearable patches due to their versatility and softness.
