The present study was carried out to investigate the effect of ultrasound-assisted extraction (UAE) method on physicochemical and molecular properties of hull-less barley β-d-glucan. With increasing sonication time, β-d-glucan flow behavior index (n) and its extraction yield significantly increased while its consistency coefficient and lightness decreased. Sonication time had no significant effect on β-d-glucan purity, emulsion and foam stabilizing effect and colour. Increasing pH from 5 to 9 significantly enhanced extraction yield, purity, consistency coefficient (k), emulsion stabilizing effect and yellowness of the final product...

The treatment of patients with oral cancer is complex: a multidisciplinary approach needs to be taken and maxillofacial and oral surgeons, an oncologist, a prosthodontist should be included, and a psychologist is often needed. This case report describes the prosthetic rehabilitation of a patient after surgical removal of oral cancer with obturator prosthesis. Resection cavity was located in central part of the hard palate and the condition belonged to Aramany class 3 maxillary defects. The two-step impression technique of denture bearing area was used and the resection of cavity was performed...

Donor-site wound healing was tested with a silver sulfadiazine (SSD)-impregnated hydrocolloid dressing and hydrocolloid dressing applied manually by a physician on site. A total of 14 patients, 5 woman and 9 men (23-89 years old, average = 61.6 ± 18.70 years), were enrolled in this prospective controlled study. The degree of bleeding was significantly less with the SSD-impregnated than with the hydrocolloid dressing (P < .01). In the moisture meter analysis, the values of the effective contact coefficient and corneal thickness were significantly smaller with the SSD-impregnated dressing (P < ...

This review discusses recent understanding of the oral destabilization of food emulsions from a colloidal perspective. The review deals mainly with the microstructural changes in emulsions and emulsion gels during oral processing at a colloidal length scale, with the key emphasis being on the role of electrostatic interactions, enzymatic modifications and surface-induced phenomena. Knowledge of these complex interactions between the emulsion droplets and the oral components, such as salivary proteins, enzymes and oral shear, might be the key to understanding the oral behaviour and sensory perception of food emulsions...

Materials manufacturing industries seek efficient, economic, and sustainable compounds for stabilizing dispersed systems such as emulsions. In this study, novel, abundant biobased hydrocolloids spruce galactoglucomannans (GGM) and birch glucuronoxylans (GX) were obtained from a forestry biorefining process and characterized as versatile stabilizers of rapeseed oil-in-water emulsions. For the first time, GGM and GX isolated by pressurized hot water extraction (PHWE) of spruce and birch saw meal, respectively, were studied in emulsions...

BACKGROUND: Noninvasive positive pressure ventilation (NPPV) provides ventilation without tracheal intubation. Facial pressure injury is a recognized complication of this technique, making the prevention of facial pressure injuries an important issue for NPPV patients. PURPOSE: The present study compared the effects of foam dressing and hydrocolloid dressing in preventing facial pressure injuries in NPPV patients. METHODS: A randomized clinical trial was used to evaluate participants that were referred from the intensive care unit of a medical center in eastern Taiwan...

BACKGROUND: Nurses have a primary role in promoting neonatal skin integrity and skin care management of the critically ill neonate. Adhesive products are essential to secure needed medical devices but can be a significant factor contributing to skin breakdown. Current literature does not offer a definitive answer regarding which products most safely and effectively work to secure needed devices in the high-risk neonatal population. PURPOSE: To determine which adhesive method is best practice to safely and effectively secure lines/tubes in the high-risk neonate population...

The main aim of this study was to develop rice starch (RS), ι-carrageenan (ι-car) based film. Different formulations of RS (1-4%, w/w), ι-car (0.5-2%, w/w) was blended with stearic acid (SA; 0.3-0.9%, w/w) and glycerol (1%, w/w) as a plasticizer. The effect of film ingredients on the thickness, water vapour permeability (WVP), film solubility (FS), moisture content (MC), colour, film opacity (FO), tensile strength (TS), elongation-at-break (EAB) of film was examined. Interactions and miscibility of partaking components was studied by using Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD)...

A single emulsifier material is seldom sufficient to cater to the requirements of complex emulsion-based food formulations that have to function over a wide range of pH, ionic strength, storage time and temperature. Food emulsions have to be designed to satisfy several requirements for use which could be achieved by combining the beneficial properties of multiple emulsifiers. This article reviews novel biological materials that are used to design oil-in-water (o/w) emulsions. More specifically, the major focus is to discuss (o/w) interfaces stabilized by multiple biopolymers...

The development and utilization of three-dimensional cell culture platforms has been gaining more traction. Three-dimensional culture platforms are capable of mimicking in vivo microenvironments, which provide greater physiological relevance in comparison to conventional two-dimensional cultures. The majority of three-dimensional culture platforms are challenged by the lack of cell attachment, long polymerization times, and inclusion of undefined xenobiotics, and cytotoxic cross-linkers. In this study, we review the use of a highly defined material composed of naturally occurring compounds, hyaluronic acid and chitosan, known as Cell-Mate3DTM...

Hydrocolloid interactions with solvent/cosolutes play a vital role in the resolution of their functional properties. Basil seed gum (BSG) is a plant-derived hydrocolloid which has been found many applications in food formulations as stabilizer, emulsifier, thickener and gelling agents. Sucrose and lactose are the most effective sugars in textural and sensorial properties of bakery and dairy products which adding them to solutions containing hydrocolloids can be helpful to approach a proper formula. In this paper, the effect of temperature (25-65°C), sucrose (10, 20, 30 and 40%) and lactose (5, 10 and 15%) were investigated through some molecular parameters of BSG...

Diabetic foot ulcers and venous leg ulcers are chronic wounds frequently encountered by dermatologists. Choosing appropriate wound dressings can effectively promote wound healing and potentially reduce morbidity and financial burden experienced by patients. The objective of our systematic review and meta-analysis was to evaluate wound healing efficacies of synthetic active dressings in diabetic foot ulcer and venous leg ulcer management. For data collection, PubMed, Embase, Cochrane Library, CINAHL, and clinicaltrials...

Bio-active bi-layer thin film having both bio-adhesive and non-adhesive end composed of polyvinyl alcohol (PVA) and gelatin/chitosan/polyethylene glycol (PEG) blend was developed for biomedical applications especially as an alternative of advanced tissue scaffold. The developed composite film was subjected to mechanical, thermal and physico-chemical characterization such as tensile strength (TS) and elongation at break (Eb), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), fluid drainage capacity and biocompatibility...

OBJECTIVE: Contact allergies can occur frequently in patients with chronic leg ulcers (CLUs), even in those with a short duration of ulcerative disease. The wide spectrum of therapeutic products promotes development of the delayed type of hypersensitivity and continuous changes in the allergens pattern, which make the diagnosis and treatment extremely difficult in many cases. A prompt diagnosis and treatment of allergic contact dermatitis (ACD) in patients suffering from CLUs is very important for a best clinical outcome of these two common diseases...

The objective was to evaluate the potential of birch xylan as a food hydrocolloid and dietary fibre. High-molecular weight xylan was isolated from birch kraft pulp by alkaline extraction, and enzymatically hydrolysed. Fermentability of xylans was evaluated using an in vitro colon model and performance as a hydrocolloid was studied in low-fat acid milk gels (1.5% and 3% w/w). Texture of the gels and water holding capacity of xylans were compared with inulin, fructooligosaccharide and xylooligosaccharide. Xylans showed slower fermentation rate by faecal microbiota than the references...
