Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Augmentation powers and group homology
It is well-known that low-dimensional group homology provides a useful tool for studying lower central series, dimension subgroups and augmentation powers of group rings. The aim of this paper is to extend these methods to the study of transfinite augmentation powers and, more generally, to the study of two-sided ideals in group rings and the normal ...

Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

The cyclic homology of the group rings
Let G be a discrete group. For \(x\in G\), denote by \(G_ x\) the centralizer of x and by \(N_ x\) the quotient of \(G_ x\) by the subgroup generated by x. Write \(=_ f\cup _{\infty}\) for the decomposition of the conjugacy classes of G into classes \(\bar x\) with the property that ord x\(

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

Homology groups of steiner systems
To each Steiner system (X,B) a finite simplicial complex K(X,B) is associated, whose homology groups afford a representation of the automorphism group of the system (in particular, projective and affine planes give the Steinberg representations of PSL(3,q) and of AFF(2,q)).

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.
