Health Passport: A blockchain-based PHR-integrated self-sovereign identity system

Frontiers in Blockchain, 2023
During the COVID-19 pandemic, it was necessary to validate a person’s health status along with their identity to permit travel. This was facilitated via paper-based certificates and centralized digital apps.

A Novel Model for Authority and Access Delegation Utilizing Self-Sovereign Identity and Verifiable Credentials

IEEE Access
Self-Sovereign Identity (SSI) is a decentralized, user-centric approach to Identity Management (IdM), that allows users to gain control over their digital identity and data.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
