“BACKGROUND The treatment of ingrown toenail is usually bothersome for patients and doctors.
OBJECTIVES To compare two treatment techniques of ingrown toenails-phenol
matricectomy (PM) and nail-splinting using a flexible tube (FT)-in terms of efficacy, postoperative pain, postoperative cosmetic satisfaction, amount of tissue damage, and recurrence.
METHODS AND MATERIALS One hundred twenty ingrown toenails were randomized and divided into PM and FT groups. All cases were evaluated 2 days and 1 and 6 months after treatment. Postoperative pain, cosmetic satisfaction, time to recovery, and recurrence rate were measured.
RESULTS Postoperative pain was less and cosmetic satisfaction was Selleckchem Quisinostat good in selleck products both groups (p < .001). Our recurrence rate was 8.4%. There were no statistical differences between groups in these measures. Tissue improvement rate was 6% in the PM group and 93% in the FT group 2 days after the procedures (p < .001).
CONCLUSIONS Although FT provides faster
recovery and less postoperative morbidity than PM, the techniques are equally effective in treating ingrown toenails.”
“Epoxy resins are hardly toughened by low weight content of tougheners. In this study, 5 wt % polyurea was adopted to significantly toughen piperidine-cured epoxy, as fracture toughness improved from 0.78 to 1.98 MPa m(1/2) We focused on the reactions and morphology evolution of epoxy/polyurea mixture. The polyurea molecular weight was reduced by the exchange reactions of polyurea with epoxy during mixing, as evidenced by gel permeation chromatograph and Fourier transform infrared spectroscopy. As a result, epoxy molecules were chemically bonded with polyurea, improving particle content and interface Epigenetic inhibitor price thickness. Transmission electron microscope observation shows that (a) polyurea in situ formed nanoparticles in matrix which subsequently aggregate into micron-sized particles of thick interface with matrix; and (b) the particles became less stainable with increasing the mixing time, because the reactions promoted
high levels of crosslink density of the particles which were thus more resistant to the diffusion of staining chemicals. Longer mixing time improved, obviously, the fracture toughness of epoxy/polyurea composite. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 115: 3265-3272,2010″
“‘Requeijao cremoso’ is a spreadable processed cheese that shows ample acceptance on the Brazilian market. In this work, analogues of this cheese, made by substituting 25% and 50% of the dairy fat with vegetable fat, were studied with respect to physical-chemical composition, texture profile, microstructure and sensory acceptance. The substitution of part of the dairy cream by vegetable fat resulted in increased adhesiveness and hardness.
