Non-standard sequences

Математичні Студії
The paper shows the existence of a previously unknown relationship between the theory of monoids and category theory. A non-standard mathematical method based on terms from non-standard (not always existing) sequences is proposed.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Canadian Retail Survey of Gluten-Free Products and Products That Contain Inherently Gluten-Free Ingredients

Journal of Food Protection
Given the abundant presence of retail products with gluten-containing cereal grains (wheat, barley, and rye), the strict avoidance of gluten can be challenging, and consumers with a gluten sensitivity will look for gluten-free equivalent products.

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

ТАУБЕРОВЫ ТЕОРЕМЫ С МЕДЛЕННО МЕНЯЮЩИМИСЯ С ОСТАТКОМ ФУНКЦИЯМИ И ИХ ПРИЛОЖЕНИЯ

Проблемы анализа, 2012
E. Wirsing setted up a problem in 1967 year: Is it possible to reduce the estimation ∑n≤xf(n)=o(xlogx∑n≤xf(n)n),x→∞\eqno(1) from the estimation ∑p≤xf(p)logpp=o(logx),x→∞.\eqno(2) Here n is a positive enteger, p is a prime number.

Geometrisation of Ohm’s reciprocity relation in a holographic plasma

Journal of High Energy Physics
It has been recently pointed out that the familiar reciprocity relation between the conductivity σ and resistivity ρ, which I refer to as Ohm’s reciprocity relation, should not be expected to hold in all possible settings, but is rather a property that ...

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

FEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...
