Prognostic Impact of Spontaneous Conversion to Sinus Rhythm in Patients With Symptomatic Paroxysmal Atrial Fibrillation: A Propensity-Matched Follow-Up Study. [PDF]

open access: yesJ Cardiovasc Electrophysiol
ABSTRACT Background Paroxysmal atrial fibrillation (PAF) patients do not invariably progress to persistent AF, with a consistent group of patients showing AF regression during follow‐up. The prognostic implications of spontaneous conversion (SCV) to sinus rhythm (SR) in those patients has never been evaluated yet.

Late Holocene technological provisioning at the Kings Table rockshelter, Blue Mountains, New South Wales, Australia

open access: yesArchaeology in Oceania, Volume 58, Issue 3, Page 227-244, October 2023., 2023
ABSTRACT Technological analysis of the late Holocene component of the stone artefact assemblage recovered from the Kings Table rockshelter in the Blue Mountains, west of Sydney, provides the basis for an assessment of the site's role in broader late Holocene settlement‐subsistence systems. Drawing on Kuhn's widely employed “provisioning model”, as well

Jacques de Vitry (d. 1240) and the Religious Life of his Time

open access: yesHistory, Volume 108, Issue 379-380, Page 3-19, April 2023., 2023
Abstract In this article the scholar, preacher and bishop Jacques de Vitry (d. 1240) is taken as a vantage point to look at the religious life of his time. He had personal involvement with the nascent university of Paris, the earliest beguines of the Low Countries, the crusades against heretics and Muslims, and the first friars.

Lipoplex‐Functionalized Thin‐Film Surface Coating Based on Extracellular Matrix Components as Local Gene Delivery System to Control Osteogenic Stem Cell Differentiation

open access: yesAdvanced Healthcare Materials, Volume 12, Issue 5, February 17, 2023., 2023
An extracellular matrix‐inspired polyelectrolyte multilayer film is functionalized with lipoplexes and used as gene activated biomaterial surface coating for application in regenerative medicine. Collagen I‐chondroitin sulfate multilayers with embedded lipoplexes having plasmids encoding for bone morphogenic protein 2 gene promote adhesion and growth ...

Amination of Polymeric Braid Structures to Improve Tendon Healing: An Experimental Comparison

open access: yesMacromolecular Materials and Engineering, Volume 308, Issue 1, January 2023., 2023
Poly(ethylene terephthalate) (PET) and poly(lactic acid) (PLA) are polymers useful in tendon repair, though with minimal success. There is a need to improve such scaffolds' design and physical–chemical nature. The work concerns functionalization of PET/PLA braids to incorporate amine groups in the braids' surface, improve cell adhesion, and ...

Evaluation of plant extracts as an efficient source of additives for active food packaging

open access: yesFood Frontiers, Volume 3, Issue 3, Page 480-488, September 2022., 2022
Natural extracts from aromatic plants as additives for active food packaging film. Abstract Natural extracts have been used in several traditional medicine applications and culinary purposes. Their biological properties (antioxidant and antimicrobial) are due to the presence of several active aromatic compounds.

Treatment of Silylene–Phosphinidene with Chalcogens Resulted Exclusively in the Formation of Silicon‐Bonded Chalcogens

open access: yesChemistry – A European Journal, Volume 25, Issue 49, Page 11422-11426, September 2, 2019., 2019
Join the main‐group meeting: Chalcogen‐bonded silicon(IV) phosphinidenes LSi(E)−P−MecAAC (E=S, Se, Te) were synthesized from the reactions of silylene–phosphinidene LSi−P−MecAAC with elemental chalcogens. These are the first molecular examples in which a Si=E group is attached to a phosphinidene moiety.

Electrodeposition of 4‐Benzenesulfonic Acid onto a Graphite‐Epoxy Composite Electrode for the Enhanced Voltammetric Determination of Caffeine in Beverages

open access: yesJournal of Analytical Methods in Chemistry, Volume 2019, Issue 1, 2019., 2019
Caffeine is widely present in food and drinks, such as teas and coffees, being also part of some currently commercialized medicines, but despite its enhancement on several functions of human body, its exceeding use can promote many health problems. In order to develop new fast approaches for the caffeine sensing, graphite‐epoxy composite electrodes ...
