A glue stick is comprised of solidified adhesive mounted in a lipstick-like push-up tube. Whey is a byproduct of cheese making. Direct disposal of whey can cause environmental pollution. The objective of this study was to use whey protein isolate (WPI) as a natural polymer along with polyvinylpyrrolidone (PVP) to develop safe glue sticks. Pre-dissolved WPI solution, PVP, sucrose, 1,2-propanedio...

Objectives: To compare the bond strength of printed and conventionally produced denture base resins to reline after being submitted a physical-chemical aging process. Methods: Sixty specimens (10×10×3.3 mm) two (V-Print Dentbase Denture 3D+) one (Probase Hot) were relined with acrylic resins: Ufi Gel Hard C Probase Cold (n=10). The 1000 cycles thermal fluctuations (5-55ºC) 28 days pH using pH=3...

The interface between skin and electrodes plays a major role in the accuracy efficiency of biopotential measurements. For reliable biosignal recording, stable low-impedance contact is required target tissue. Conventional wet (Ag/AgCl) are composed metal with skin-adhesive hydrogel. However, for long-term measurement, direct pre-gel electrode causes discomfort irritation, especially infants peop...

Anchote is a tuber crop indigenous to Ethiopia. Starch hydration properties and important gel characteristics which include: color, rheological (at 2, 4, 6, 8, 10% starch:water w/w) texture evolution w/w), during 0 192 h storage 4 °C), of anchote starches isolated from four cultivars (Desta 01, Desta 24, white red) were evaluated compared with potato cassava (PS CS). The lightness (L*) whitenes...

topical drug dosage forms such as ointments and creams can be easily removed through wetting, movement and contact. the new bioadhesive formulations with enhanced local anesthetic effects are needed for topical administration. the adhesive capacity of hydroxypropyl methylcellulose (hpmc) was determined by measuring the maximum detachment force and the adhesion work with an auto peeling tester. ...
