A Knowledge and Evaluation Model to Support the Conservation of Abandoned Historical Centres in Inner Areas

open access: yesHeritage
The planning of interventions aimed at preserving the built heritage of inner areas is a complex process due to the fragility of these contexts. It should stem from adequate knowledge to support the recognition of qualities, resources, and potentials ...

Invertible Measure Preserving Transformations and Pointwise Convergence [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
An investigation of pointwise convergence of sequences {2. _a'f(T-x) :k= 1, 2,* } wheref lies in the space L1([O, 1]) of Lebesgue integrable functions on the unit interval, T is an invertible measure preserving transformation on [0, 1], and the sequence of polynomials { kz-j=1, 2, } is uniformly bounded and pointwise convergent for all z such that JzJ =

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Ergodic Measure Preserving Transformations of Finite Type

open access: yesTokyo Journal of Mathematics, 1988
Let T be an invertible ergodic measure preserving (e.m.p.) transformation of an infinite \(\sigma\)-finite Lebesgue measure space (X,\({\mathcal B},m)\). A set W is called weakly wandering (w.w.) if there exists a strictly increasing sequence \((n_ i)\) of integers such that \(T^{n_ i}W\cap T^{n_ j}W=\emptyset\) for \(i\neq j\); and \((n_ i)\) is ...

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Groups of measure preserving transformations

open access: yesMathematische Annalen, 1988
Let G be a group of measure-preserving transformations on a non-atomic probability measure space \((X,{\mathcal B},\mu)\) (if we are interested in the according topological versions we assume that G is locally compact and the action on the sets \(A\in {\mathcal B}\) is continuous with respect to the metric \(\rho (A,B)=\mu (A\Delta B)).\) The main ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...
