Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Influence of fertilization modules on economics and profitability of rooted carnation (Dianthus caryophyllus) cutting production

open access: yesThe Indian Journal of Agricultural Sciences, 2016
An experiment was conducted to evaluate the economics and profitability of rooted carnation (Dianthus caryophyllus L.) cutting production influenced by fertilizer modules. Four commercial carnation cultivars, viz. White Wedding, Farida, Niva, Madras and

The Hochschild-Serre property for some p-adic analytic group actions

open access: yes, 2015
Let $H \subseteq G$ be an inclusion of $p$-adic Lie groups. When $H$ is normal or even subnormal in $G$, the Hochschild-Serre spectral sequence implies that any continuous $G$-module whose $H$-cohomology vanishes in all degrees also has vanishing $G ...

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Secondary multiplication in Tate cohomology of generalized quaternion groups [PDF]

open access: yes, 2009
Let k be a field and let G be a finite group. By a theorem of D.Benson, H.Krause and S.Schwede, there is a canonical element in the Hochschild cohomology of the Tate cohomology HH^{3,-1} H*(G) with the following property: Given any graded H*(G)-module X,

Restrictions of generalized Verma modules to symmetric pairs

open access: yes, 2012
We initiate a new line of investigation on branching problems for generalized Verma modules with respect to complex reductive symmetric pairs (g,k). Here we note that Verma modules of g may not contain any simple module when restricted to a reductive ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Zip Property on Malcev-Neumann Series Modules

open access: yesLe Matematiche, 2015
Let R be a ring, MR a right R-module, G a totally ordered group, σ a map from G into the group of automorphisms of R which assigns to each x ∈ G an automorphism σ_x ∈ Aut(R), τ a map from G × G to U(R) (the group of unit elements of R) and M((G; σ ; τ ...

On coomologies of the Klein four-group

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017
A free resolution of the trivial G-module Z, where G is the Klein four-group, is constructed. Its relation with the standard resolution is established. Also H2 (G, M) for some modules M is calculated.

Dimensional accuracy of 3D printing navigation templates of chemical-based sterilisation

open access: yesScientific Reports, 2022
3D printed navigational templates have facilitated the accurate treatment of orthopaedic patients. However, during practical operation, it is found that the location hole occasionally deviates from the ideal channel.
