Xiao-Ping Qiao, Yan-Zhen Ge
The aim of the study was to investigate the application of hydrocolloid dressings in the prevention and treatment of infant diaper rash. A total of 210 infants with diaper rash were included in the study and randomized into 3 groups of 70 infants. Infants in group A received hydrocolloid dressings and individualized nursing; infants in group B received mupirocin plaster and topical application of pearl powder as well as routine nursing; and infants in group C received zinc oxide plaster and routine nursing...

Natural polymer-based hydrogel films have great potential for biomedical applications and are good candidates for wound dressings. In this study, we aimed to develop simvastatin-loaded crosslinked alginate-pectin hydrogel films by ionic crosslinking to improve the mechanical characteristics, wound fluid uptake and drug release behavior. Alginate-pectin hydrocolloid films were chemically crosslinked by immersing in different concentrations of CaCl2 (0.5-3% w/v) for 2-20min. The degree of crosslinking was influenced by both contact time and CaCl2 concentration...

OBJECTIVES: The aim was to evaluate the effect of adding povidone (PVP) iodine powder with different concentrations to irreversible hydrocolloid on both microbiological and dimensional stability. MATERIALS AND METHODS: Regular set of (alginate) irreversible hydrocolloid was selected as control group. PVP-iodine powder was mixed with the alginate powder at concentrations of 1, 5, 10, 15, and 20% by weight (test groups). All specimens were tested for their antimicrobial effect against Streptococcus mutans and Staphylococcus aureus as well as dimensional stability...

Natural polysaccharides are the most widely used biopolymers for green synthesis of eco-friendly silver nanoparticles (AgNPs). In a previous study, a high molecular weight (MW) fraction of exopolysaccharides (EPS) produced by a medicinal fungus Cs-HK1 has been shown useful for green and facile synthesis of AgNPs in water. This study was to further evaluate the effects of molecular properties of EPS on the formation, stability and properties of AgNPs with different EPS fractions at various pH conditions. Three EPS fractions (P0...

This work considered gelatinized wheat flour fraction with properties similar to hydrocolloid to enhance the strength of dough network by improving water retention and rheological characteristics. The gelatinized (90 °C) fraction of the wheat flour was incorporated in the dough formulation at different levels (5, 10, and 20% w/w). The effects of the gelatinized flour (GF) fraction on the dough rheology and thermal properties were studied. The incorporation of GF induced a moderate increase of dough viscoelasticity and reduced the freezing and melting enthalpies...

BACKGROUND: Surgical wounds (incisions) heal by primary intention when the wound edges are brought together and secured, often with sutures, staples, or clips. Wound dressings applied after wound closure may provide physical support, protection and absorb exudate. There are many different types of wound dressings available and wounds can also be left uncovered (exposed). Surgical site infection (SSI) is a common complication of wounds and this may be associated with using (or not using) dressings, or different types of dressing...

The aim of the current paper was to investigate the effect of different temperatures, salts and sugars on dilute solution properties of Prunus armeniaca gum exudates (PAGE) as a starting point to evaluate the potential utilization of this novel source of hydrocolloids in food and pharmaceutical systems. Berry number and the slope of master curve indicated that PAGE samples in all evaluated conditions were in dilute domain without coil overlapping and entanglement. Furthermore, the slope power law model also demonstrated that the molecular conformation of PAGE in all tested temperatures was close to rode-like...

Most stoma flanges are made of hydrocolloid material. Hydrocolloid is a hydrophilic material that attracts water, potentially resulting in moisture becoming trapped between the flange and skin. Also, as hydrocolloids are absorbent, the material breaks down over time, and there is a risk that some of the adhesive can remain on the skin on removal. Unlike hydrocolloids, silicone comprises fully cross-linked silicone polymers whose properties have been engineered to manage moisture without breaking down (i.e. manage the transepidermal water loss (TEWL))...

In this study nanofibers were prepared via the electrospinning technique by basil seed mucilage (BSM) as a new source of hydrocolloid. Polyvinyl alcohol (PVA) was used as an aiding agent. Viscosity and electrical conductivity of BSM/PVA solutions of different volume ratios (100:0, 80:20, 60:40, 40:60, 20:80 and 0:100) were in the range of 790-1300cP and 745-2140μS/cm, respectively. Morphology of nanofibers were investigated using scanning electron microscopy (SEM) that showed an average diameter range of 179-390nm...

STATEMENT OF PROBLEM: The masticatory efficacy between dentate and edentulous individuals with and without the use of dental adhesives has been little studied. A comparative study of the addition of various agents of synthetic adhesion (vinyl methyl ether versus polyvinyl acetate) to these adhesives is needed. PURPOSE: The purpose of this randomized, crossover, double-blind clinical trial was to compare the masticatory efficacy of wearers of complete dentures with and without dental adhesives of 2 different compositions and that of dentate controls...

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 < ...

REVIEW
Anwesha Sarkar, Aiqian Ye, Harjinder Singh
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...
