Diabetic foot ulcers (DFUs) are associated with an increased risk of secondary infection and amputation. Platelet-rich fibrin (PRF), a platelet and leukocyte concentrate containing several cytokines and growth factors, is known to promote wound healing. However, the effect of PRF on diabetic wound healing has not been adequately investigated. The aim of the study was to investigate the effect of PRF on skin wound healing in a diabetic mouse model. Platelet-rich fibrin was prepared from whole blood of 8 healthy volunteers...

Mimicking skin extracellular matrix hierarchy, the present work aims to develop a bilayer skin graft comprising a porous cotton-wool-like 3D layer with membranous structure of PCL-chitosan nanofibers. Emulsion electrospinning with differential stirring periods of PCL-chitosan emulsion results in development of a bilayer 3D structure with varied morphology. The electrospun membrane has fiber diameter ∼274 nm and pore size ∼1.16 μm while fluffy 3D layer has fiber diameter ∼1.62 μm and pore size ∼62 μm...

As a new generation of negative pressure drainage technology, vacuum-assisted closure (VAC) can provide stable and persistent negative pressure, and there are several modes to choose from. VAC plays an important role in closing wounds quickly, controlling infection, promoting angiogenesis, increasing blood flow, and promoting granulation tissue growth of wounds. It is now widely applied in all kinds of acute, chronic, and special wounds in clinic with good therapeutic results. However, we need to pay attention to contraindications and complications of VAC when it is used, avoiding secondary damage due to improper treatment...

Reconstructing functional skin after a wound remains a challenge due to the complexity of healing. In this regard, biocompatible nanoparticles (NPs) carrying and releasing bioactive drugs in a controlled and sustained manner may significantly improve the efficacy of wound therapies compared with current treatments. Topical administration of drug-loaded NPs allows optimal delivery to the dermis and improves product efficacy. Furthermore, associating NPs with scaffolds represents a new concept of 'dressing'. Experimental in vivo, ex vivo, and in vitro models have been developed in preclinical assays to evaluate the beneficial effects of nanoparticulate dressings...

We find an exact analytical solution to the exchange-only time-dependent density-functional theory (TDDFT) problem for a significant class of quasi-low-dimensional (QLD) materials: QLD electron gas with only one band filled in the direction perpendicular to the layer or wire. The theory yields the TD exchange potential as an explicit nonlocal operator of the TD spin density. The dressed interband (image states) excitation spectra of quasi-two-dimensional electron gas are obtained, while the comparison with the Kohn-Sham transitions provides insights into the qualitative and quantitative role of the many-body interactions...

The two-photon dressing of a "three-level ladder" system, here the ground state, the exciton, and the biexciton of a semiconductor quantum dot, leads to new eigenstates and allows one to manipulate the time ordering of the paired photons without unitary postprocessing. We show that, after spectral postselection of the single dressed states, the time ordering of the cascaded photons can be removed or conserved. Our joint experimental and theoretical study demonstrates the high potential of a "ladder" system to be a versatile source of orthogonally polarized, bunched or antibunched pairs of photons...

Methylated spirit burns have been reported following domestic uses such as igniting fondues. It has also been used as an accelerant for self-immolation. We report the first documented case of severe methylated spirit burns sustained during traditional hair dressing. Increased awareness on the dangers of methylated spirit as well as making it less readily available for domestic use is warranted.

INTRODUCTION/BACKGROUND: Xeroform(®) is a petrolatum-based fine mesh gauze containing 3% bismuth tribromophenate. Bismuth, similar to other metals, has antimicrobial properties. Xeroform(®) has been used for decades in burn and plastic surgery as a donor site dressing and as a covering for wounds or partial thickness burns. Despite this, the antimicrobial spectrum of Xeroform(®) remains largely unknown. We examined the in-vitro efficacy of Xeroform(®) against common burn pathogens using zone-of-inhibition methodology in a commercial research facility...

Over the past decade, interest in caveolae biology has peaked. These small bulb-shaped plasma membrane invaginations of 50-80nm diameter present in most cell types have been upgraded from simple membrane structures to a more complex bona fide organelle. However, although caveolae are involved in several essential cellular functions and pathologies, the underlying molecular mechanisms remain poorly defined. Following the identification of caveolins and cavins as the main caveolae constituents, recent studies have brought new insight into their structural organization as a coat...

BACKGROUND: Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Dressings are widely used to treat pressure ulcers and promote healing, and there are many options to choose from including alginate, hydrocolloid and protease-modulating dressings. Topical agents have also been used as alternatives to dressings in order to promote healing.A clear and current overview of all the evidence is required to facilitate decision-making regarding the use of dressings or topical agents for the treatment of pressure ulcers...

There is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring coherent adiabatic quantum dynamics. Here we show that combining the well-developed quantum simulation toolbox for Rydberg atoms with the recently proposed Lechner-Hauke-Zoller (LHZ) architecture allows one to build a prototype for a coherent adiabatic quantum computer with all-to-all Ising interactions and, therefore, a platform for quantum annealing...

Chronic wounds are associated with financial and personal costs. The system level expense associated with chronic wounds has been established, however, the out-of-pocket cost incurred by individuals who self-fund has not been the focus of extensive investigation. Recently, there has been renewed interest in evaluating quality of life, in line with the shift to patient enablement and self-care in chronic disease management. The objectives of this research were to describe the out-of-pocket wound treatment costs and the quality of life of people who have chronic wounds...
