Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

llc: a collection of R functions for fitting a class of Lee-Carter mortality models using iterative fitting algorithms [PDF]

open access: yes, 2009
We implement a specialised iterative regression methodology in R for the analysis of age-period mortality data based on a class of generalised Lee-Carter (LC) type modelling structures.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Extending the Normativity of the Extended Family: Reflections on \u3ci\u3eMoore v. City of East Cleveland\u3c/i\u3e [PDF]

open access: yes, 2017
Part I of this Article briefly recounts the plurality decision in Moore before analyzing Justice Brennan’s concurring opinion and detailing how the concurrence affirms, rather than deconstructs, the notion of African American deviance in families.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Pedagogia fenomenologica e interpretazione della devianza / Pédagogie phénoménologique et interprétation de la déviance / Phenomenological pedagogy and interpretation of deviance [PDF]

open access: yesRivista di Criminologia, Vittimologia e Sicurezza, 2010
Phenomenological pedagogy, introduced by Piero Bertolini in the second half of the past century, gets its fundamental and basic requirements from the phenomenology of Husserl, a German philosopher operating during the first years of 20th century.This ...
