Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

The effect of moving metal wall on microwave heating uniformity

open access: yes四川大学学报. 自然科学版, 2017
In this paper, the phase of electromagnetic field distribution in the cavity is regulated through movements of the metal wall of a rectangular waveguide, which can avoid the inhomogeneous heating caused by the uneven distribution of electromagnetic field

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Harnack Type Inequality: the Method of Moving Planes [PDF]

open access: yesCommunications in Mathematical Physics, 1999
Let \((M,g)\) be a compact Riemann surface without boundary and let \(\Delta_{g}\) be the associated Laplace-Beltrami operator. The main purpose of the paper is to provide a careful analysis of blowup solutions \((\xi_{n})\) in \(C^{2}(M)\) to the problems \[ - \Delta_{g} \xi_{n} = \lambda_{n} (V_{n} e^{\xi_{n}} - W_{n}) \quad\text{on \(M\)} , \qquad ...

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Optimal Coordinated Motions of Multiple Agents Moving on a Plane

open access: yesSIAM Journal on Control and Optimization, 2003
The authors examine the problem of optimal coordinated motions of multiple agents moving in the same planar region. The objective is to determine the conflict-free maneuvers (motions) with the least combined energy and taking into account the different priorities of the agents.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

A Liouville Theorem for Nonlocal Equations in the Heisenberg Group

open access: yesBruno Pini Mathematical Analysis Seminar, 2014
We establish a Liouville-type theorem for a subcritical nonlinear problem, involving a fractional power of the sub-Laplacian in the Heisenberg group. To prove our result we will use the local realization of fractional CR covariant operators, which can be
