DNA ligase LigE increases bacterial transformation with damaged extracellular DNA
FEBS Letters, EarlyView.The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

ON SOME CLOSURE OPERATORS ON SEMIGROUPS
Demonstratio Mathematica, 1991 Let \(S\) be a semigroup, \(M \subseteq S\). We define \(N_ 1(m) = \{x\in S; x^ n\in M\) for almost all \(n\in N\}\), \(N_ 2(M)=\{x\in S; x^ n\in M\) for infinitely many \(n\in N\}\), \(N_ 3(M) = \{x \in S; x^ n \in M\) for at least one \(n\in N\}\), \(U_ 1(M) = N_ 1(M)\cup M\) and \(U_ 2(M) = N_ 2(M)\cup M\). In this paper the authors study topologies

A self adjoint expansion of a symmetric differential operator with operator coefficient
, 2007 In this work, we prove that the closure of a symmetric operator L0which is formed by differential expression(L0y)(x) = −(p(x)y(x)) − Q(x)y(x)and with the boundary conditioncos α.y(0) + sinα.y(0) = 0is self adjoint where α ∈ (−∞,∞) in the space L2(0,∞; H )

FEBS Letters, EarlyView.Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

On the closure operator and the closure system of many sorted sets
, 1996 Summary. In this paper definitions of many sorted closure system and many sorted closure operator are introduced. These notations are also introduced in [9], but in another meaning.

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
