Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

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.

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
FEBS Open Bio, EarlyView.Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Generalized multiplicative h-fractional integrals and derivatives with Hermite-Hadamard inequality
Journal of Inequalities and ApplicationsIn this study, we introduce new generalized multiplicative h-fractional integral and h-fractional derivative operators by employing multiplicative calculus within the framework of fractional analysis.

Weighted inequalities for multilinear fractional integral operators
Collectanea mathematica, 2009 The author considers fractional multilinear integral operators \[ {\mathcal I}_\alpha \vec{f}(x):= \int_{\left({\mathbb R}^n\right)^m } {f_1(y_1) \cdots f_m(y_m)\over \left(|x-y_1|+\dots+|x-y_m|\right)^{nm-\alpha}} d\vec{y}. \] Sufficient conditions for the two weight inequalities \[ \left(\int_{{\mathbb R}^n} (|{\mathcal I}_\alpha\vec{f}|u)^q dx\right)

On a Hardy’s inequality for a fractional integral operator
, 2018 In the present work we find inequalities that generalize some results found by Iqbal in [4, 5] regarding Riemann-Liouville fractional integral, by means of a Hardy inequality, using fractional integral operators defined by R.K. Raina in [9]

Aging and Cancer, EarlyView.This prospective study demonstrates that laparoscopic sphincter‐preserving surgery is feasible for elderly patients. While overall survival reaches 70% at 5 years, advanced T‐stage and the omission of neoadjuvant therapy significantly drive recurrence, highlighting the need for personalized geriatric protocols despite logistical challenges.
