The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

SYNTHESIS OF REVERSE TWO-BIT DUAL-OPERATED STRICTLY STRAIGHT CRYPTOGRAPHIC CODING ON THE BASIS OF ANOTHER OPERATION

open access: yesСучасні інформаційні системи, 2019
Based on the analysis of a group of two-bit two-operand operations of strict stable cryptographic coding, the relations between direct and inverse operations are established and formalized and their correctness is proved.

Random Permutations

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1968
Summary The problem of generating random permutations of the integers 1, 2, …, n arises, for example, when sampling a randomization distribution and when tables of permutations are required for application to experimental design. An algorithm is described which minimizes the amount of randomization necessary to generate a random ...

Simple permutations poset

open access: yes, 2011
This article studies the poset of simple permutations with respect to the pattern involvement. We specify results on critically indecomposable posets obtained by Schmerl and Trotter to simple permutations and prove that if $\sigma, \pi$ are two simple ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Naturecultural Permutations

open access: yesParse Journal, 2023
The greedy and unstoppable bulldozer of runaway globalisation has led to unprecedented economic growth in the world since the 1990s, but at a cost. Local realities, practices and knowledges are being smothered, and ecosystems worldwide are becoming more ...

Combinatorial analysis of the scheme of transpositions with a given number of in seccession of fixed elements

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016
We suggest the procedure of a direct enumeration of outcomes of the scheme with definite discipline of their enumeration. On this base we conduct the invesnigations in the follouing directios: finding the common number of the outcomes of the scheme ...
