Proton translocation in proteins [PDF]

, 1989
The active transport of protons across the low dielectric barrier imposed by biological membranes is accomplished by a plethora of proteins that span the ca. 40 Å of the phospholipid bilayer.

Unraveling Nanomaterials in Biomimetic Mineralization of Dental Hard Tissue: Focusing on Advantages, Mechanisms, and Prospects

Advanced Science, Volume 11, Issue 40, October 28, 2024.
Due to their nanoscale dimensions and excellent designability, nanomaterials can regulate the different stages of biomimetic mineralization of dental hard tissue. They play a corresponding role in the function of the raw materials for mineralization, mineralized microenvironment, mineralization guidance, and the function of mineralized products ...

Analysis of Atom against quantum attacks

IET Quantum Communication, Volume 5, Issue 1, Page 88-102, March 2024.
A cost estimation of Grover’s key search attack on the stream cipher Atom is provided, taking into account circuit depth restrictions specified by NIST’s PQC standardisation process. The quantum circuit of Atom is implemented using QISKIT, and the results are compared with other LFSR‐based stream ciphers, including Grain‐v1, Grain‐128‐AEAD, and Lizard.

Ruxolitinib in patients with polycythemia vera resistant and/or intolerant to hydroxyurea: European observational study

European Journal of Haematology, Volume 112, Issue 3, Page 379-391, March 2024.
Abstract Background Hydroxyurea (HU) is a commonly used first‐line treatment in patients with polycythemia vera (PV). However, approximately 15%–24% of PV patients report intolerance and resistance to HU. Methods This phase IV, European, real‐world, observational study assessed the efficacy and safety of ruxolitinib in PV patients who were resistant ...

On the Security of Sponge-type Authenticated Encryption Modes

IACR Transactions on Symmetric Cryptology, 2020
The sponge duplex is a popular mode of operation for constructing authenticated encryption schemes. In fact, one can assess the popularity of this mode from the fact that around 25 out of the 56 round 1 submissions to the ongoing NIST lightweight ...

A pentapeptide as minimal antigenic determinant for MHC class I-restricted T lymphocytes [PDF]

, 1989
Peptides that are antigenic for T lymphocytes are ligands for two receptors, the class I or II glycoproteins that are encoded by genes in the major histocompatibility complex, and the idiotypic / chain T-cell antigen receptor1–9. That a peptide must bind

New Differential‐Based Distinguishers for Ascon via Constraint Programming

IET Information Security, Volume 2024, Issue 1, 2024.
As the winner of the NIST lightweight cryptography project, Ascon has undergone extensive self‐evaluation and third‐party cryptanalysis. In this paper, we use constraint programming (CP) as a tool to analyze the Ascon permutation and propose several differential‐based distinguishers.
