Mapping of serotype-specific, immunodominant epitopes in the NS-4 region of hepatitis C virus (HCV):use of type-specific peptides to serologically differentiate infections with HCV types 1, 2, and 3 [PDF]

open access: yes, 1993
The effect of sequence variability between different types of hepatitis C virus (HCV) on the antigenicity of the NS-4 protein was investigated by epitope mapping and by enzyme-linked immunosorbent assay with branched oligopeptides. Epitope mapping of the

Diversity and complexity in neural organoids

open access: yesFEBS 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.

Antimicrobial Resistance Genes and Clonal Relationships of Duck-Derived Salmonella in Shandong Province, China in 2023

open access: yesMicroorganisms
Salmonella is a major threat to both human and animal health. However, the diversity and antibiotic resistance of animal-derived Salmonella and their association with human infections remain largely unexplored.

A Note on a Ramsey-Type Problem for Sequences [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2014
Two sequences $\{x_i\}_{i=1}^{t}$ and $\{y_i\}_{i=1}^t$ of distinct integers are similar if their entries are order-isomorphic. Let $f(r,X)$ be the length of the shortest sequence $Y$ such that any $r$-coloring of the entries of $Y$ yields a monochromatic subsequence that is also similar to $X$.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Application of sequence stratigraphic concepts to the cretaceous Urgonian carbonate platform, southeast France [PDF]

open access: yes, 1992
Carbonate platforms are increasingly being studied using sequence stratigraphic concepts and models borrowed from the study of siliciclastic shelves in passive margin settings. The direct transposition of the stratigraphic model for a siliciclastic shelf
