In this study, we developed an injectable gelatin-transglutaminase (TGase) gel for cell delivery. The procedure provides a minimally invasive approach to deliver cells into tissue in a manner that improves localization. The results indicate gelatin-TGase to be noncytotoxic and to have adhesive properties that help localize and prevent the scattering of the cells after delivery. The in situ cros...

PURPOSE To evaluate the in vitro microtensile bond strength (microTBS) of etch-and-rinse and self-etch adhesive systems to demineralized dentin after the use of a papain-based chemomechanical method. METHODS 36 demineralized human dentin slabs were randomly distributed into two groups according to the method of caries removal: (1). Mechanical removal with manual excavators; (2) Chemomechanica...

background and aims. studies have shown decreased bond strength of composite resin to human and bovine bleached enamel. this study evaluated the effect of sodium ascorbate and delayed bonding on the bond strength of two adhesive systems to bleached enamel. materials and methods. the labial surfaces of 150 sound bovine incisor teeth were abraded with abrasive paper. the teeth were randomly divid...

Suture materials and surgical knot tying techniques have improved dramatically since their first use over five millennia ago. However, the approach remains limited by the ability of the suture to transfer load to tissue at suture anchor points. Here, we predict that adhesive-coated sutures can improve mechanical load transfer beyond the range of performance of existing suture methods, thereby s...

Delivery of the drug to ocular area is blocked by protective layers covering eyes; it has always been a major problem find effective bioavailability active in due short duration precorneal majority stay. Direct delivery systems combine as well oil, solution, and suspension, result, many are not able effectively treat eye diseases. Many works have done being overcome this one which use in-situ b...

Using a combination of Monte Carlo techniques, we locate the liquid-vapor critical point of adhesive hard spheres. We find that the critical point lies deep inside the gel region of the phase diagram. The (reduced) critical temperature and density are tau(c)=0.1133+/-0.0005 and rho(c)=0.508+/-0.01. We compare these results with the available theoretical predictions. Using a finite-size scaling ...

ABSTRACT This study aimed to determine the concentration of condensed tannins in bark Mimosa tenuiflora (Willd) Poir trees. Additionally, physical-mechanical properties cross-laminated timber (CLT) panels bonded with an adhesive based on M. were assessed. Bark was collected from five The formulation synthesized by mixing powdered tannins, paraformaldehyde, and water at 50 °C under continuous st...

Surgical site infections cause significant postoperative morbidity and increased healthcare costs. Bioadhesives used to fill surgical voids and support wound healing are typically devoid of antibacterial activity. Here we report novel syringe-injectable bioadhesive hydrogels with inherent antibacterial properties prepared from mixing polydextran aldehyde and branched polyethylenimine. These adh...

Adhesives that involve adhesion to the skin have been of great technological importance inmedical or pharmaceutical fields, including recently emergingwearable sensors and electronics. The objective of this workwas to evaluate the performances of silicone-based adhesives with skin, using a peel adhesion test. Specifically, we explored the effect of adhesive cleansing, which is an inevitable dai...
