Lifespan and bioactivity improvement of bacteriophages immobilized on carboxymethylcellulose - Cationic starch-coated paper for food packaging.

Bacteriophages (phages) have a great potential to target specifically foodborne bacterial pathogens, particularly in packaging materials. However, incorporating phages into packaging surfaces requires stabilizing their structure and maintaining their infectivity during the papermaking process. In this study, several coating formulations containing various ratios of carboxymethyl cellulose, cationic starch, and glycerol were applied to a base paper to assess phage stability.

Sustainable Transformation of Cellulose-Containing Textile Waste into Multifunctional Panels with Tailored FR-Lignocellulosic Fibres.

The fashion industry significantly impacts the environment, mainly through the substantial generation of waste textiles fostered by fast fashion business models. This study introduces an innovative approach to textile waste management by recycling waste textiles without the use of chemical or mechanical treatments. Herein, we developed a method adhering to the principles of circular economy to transform these textile wastes into high-quality construction panels using a papermaking process.

A highly efficient chemical approach to producing green phosphorylated cellulosic macromolecules.

The introduction of phosphate groups into cellulosic fibers allows for the tuning of their fire resistance, chelating and metal-adhesion properties, enabling the development of flame-retardant adhesive and adsorbent materials. Toward that end, the major challenge is developing a novel efficient and environmentally friendly phosphorylation route that offers an alternative to existing methods, which can achieve the targeted properties. For this purpose, cellulosic fibers were chemically modified herein using solid-state phosphorylation with phosphoric acid and urea without causing substantial damage to the fibers.

Addition of microcrystalline cellulose to an alkyd resin/titanium dioxide film: effect on dielectric properties.

In this study, various composite films were prepared by varying the amounts of long-oil Alkyd Resin (AR), Titanium Dioxide (TiO) and Microcrystalline Cellulose (MCC). The effects of each component, TiO and MCC, on the properties and microstructure of the dry film were determined by examining images obtained by scanning electron microscopy (SEM) and studying the evolution of dielectric properties, the dielectric constant and the loss factor, against frequency at room temperature. Results showed that the introduction of the TiO/MCC powder with a weight ratio larger than 1 and a volumetric pigment concentration (VPC) less than 50% allowed a better dispersion of the particles and fitted well the Linchtencker logarithmic mixing law and the Maxwell-Garnett theory.

Progenitor-cell-enriched micrografts as a novel option for the management of androgenetic alopecia.

Regenerative medicine is a multidisciplinary field that combines engineering and life science principles to promote regeneration, potentially restoring the physiological condition in diseased tissues. Specifically, the developments of complex grafts enhance the intrinsic regenerative capacity of the host by altering its environment. Autologous micrografts obtained through Rigenera® micrografting technology are able to promote derma and bone regeneration.

Pain and Bruising Levels After Lip Augmentation: A Comparison of Anterograde and Retrograde Techniques Using an Automated Motorized Injection Device. A Blinded, Prospective, Randomized, Parallel Within-Subject Trial.

Background: Dermal fillers for lip augmentation can be injected using various techniques. Although all seem to provide acceptable results, it is not clear which technique is safer, less painful, and provides greater patient comfort.

Objective: To compare patients' self-reported pain intensity during the injection of hyaluronic acid dermal filler for lip augmentation, with 2 different techniques, anterograde versus retrograde.
