On the Groups with Homogeneous Theory
Tsukuba Journal of Mathematics, 1998 If \(2\leq m < n\) then a structure \(M\) is \((m,n)\)-homogeneous if for any \(\bar{a},\bar{b} \in M^n\), \(\bar{a}\) and \(\bar{b}\) have the same type if and only if corresponding \(m\)-subtuples have the same type. A complete theory is \((m,n)\)-homogeneous if all its subtuples are.

Covering group theory for topological groups
Topology and its Applications, 2001 The authors develop a covering theory for a large category of ``coverable'' topological groups, with a generalized notion of a cover, including a number of examples and open problems. See also the review of the second part of this paper (cf. the following review).

FEBS Letters, EarlyView.Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

Four-loop non-singlet splitting functions in the planar limit and beyond
Journal of High Energy Physics, 2017 We present the next-to-next-to-next-to-leading order (N3LO) contributions to the non-singlet splitting functions for both parton distribution and fragmentation functions in perturbative QCD. The exact expressions are derived for the terms contributing in

Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation
FEBS Letters, EarlyView.The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.

FEBS Letters, EarlyView.This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

FEBS Letters, EarlyView.In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

Neutrophil deficiency increases T cell numbers at the site of tissue injury in mice
FEBS Letters, EarlyView.In wild‐type mice, injury or acute inflammation induces neutrophil influx followed by macrophage accumulation. Mcl1ΔMyelo (neutrophil‐deficient) mice lack neutrophils, and in response to muscle injury show fewer macrophages and exhibit strikingly elevated T‐cell numbers, primarily non‐conventional “double‐negative” (DN) αβ and γδ T cells.
