Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Timed degradation of Mcl-1 controls mitotic cell death

open access: yesMolecular & Cellular Oncology, 2018
Mitotic arrest can result in cell death through the process of apoptosis. We have shown by live-cell imaging that the ubiquitin-proteasome dependent proteolysis of the apoptotic regulator Mcl-1 under the control of the anaphase-promoting complex or ...

Nonmulberry Silk Fibroin Doping Boosts Charge Transfer and Charge Injection in Aligned Polypyrrole‐Silk Scaffolds for Low‐Voltage Neurostimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Conductive silk‐polypyrrole scaffolds couple redox stability with cell‐affinitive peptides present innately in an endogenous silk fibroin, enabling optimized electrical stimulation to drive neurite outgrowth. Findings establish electrochemical‐biological link for biomaterial design rules for smart nerve guidance conduits that can provide low voltage ...

Quantification of growth hormone in serum by isotope dilution mass spectrometry [PDF]

open access: yes, 2009
Inter-assay variation of antibody based routine tests is hampering comparability of measurement results for growth hormone (GH) between different laboratories and decision making in clinical practice. Here it is demonstrated, that quantification of GH by

Multiomics Analyses Reveal an Essential Role of Tryptophan in Treatment of csDMARDs in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
Rheumatoid arthritis is a disease characterized by joint inflammation. Approximately 50% of patients show insufficient response to traditional synthetic disease‐modifying antirheumatic drugs. This study aims to elucidate differential molecular profiles of the mechanisms underlying drug responses through multi‐omics strategy.

Physicochemical Properties and In Vitro Antioxidant Activity Characterization of Protein Hydrolysates Obtained from Pumpkin Seeds Using Conventional and Ultrasound-Assisted Enzymatic Hydrolysis

open access: yesFoods
Pumpkin seed proteins (PSPs) are a promising resource for obtaining bioactive peptides but their low solubility hinders enzymatic hydrolysis, reducing yield and bioactivity. In addition, enzymatic processes require specific conditions and long processing
