Wound healing is a complex and highly regulated process that can be compromized by both endogenous and exogenous factors.1 In both primary and secondary healing it consists of a series of events characterized by inflammation, epithelialization, connective tissue deposition and contraction. The contribution of each event varies according to the type of wound.2 At any rate, the longer it takes fo...

Ecotones are interesting portions of forests where microorganisms can be studied for monitoring and diversity purposes. Given the faster life cycle these organisms, their study in such a context is important to develop models that allow us understand adaptive microbial dynamics. The main objective this was evaluate dynamics myxomycetes present leaf litter layer different geographical locations ...

Context Cacti are endemic to North and South America, but numerous species have been spread all over the world after Europeans visited Americas. Their global has impacted various aspects of terrestrial ecosystems, including distributions succulenticolous myxomycetes. Aims In this study, we examine association myxomycetes (also known as plasmodial slime moulds or myxogastrids) with three introdu...

background : in recent years tissue engineering developed to replace or repair damaged tissues using cell and biomaterial. one of the most important fields of tissue engineering is simulation of in vivo micro environment of body tissues. this study aimed to develop culture chamber and cell biomaterial sheet engineering for the reconstruction of cartilage tissue. methods : stainless steel cultur...

introduction for dose measurement in megavoltage (mv) photon beams with ion chambers, the effect of volume occupied by the air cavity is not negligible. therefore, the result of measurement should be corrected with a displacement perturbation correction factor (pdis) or using an effective point of measurement (epom). the aim of this study is to calculate the epom for cylindrical ion chamber and...

introduction computed tomography scans are a very important tool for diagnosis and assessment of response to treatment in the practice of medicine. ionizing radiation in medical imaging is undoubtedly one of the most powerful diagnostic tools in medicine. yet, as with all medical interventions, there are potential risks in addition to the clear potential benefits. materials and methods two refe...

This study evaluated the effect of organic solvent (acetone or ethanol) on the microtensile bond strengths (MTBS) of an adhesive system applied to dry and moist dentin. Sixteen extracted human third molars were ground to expose a flat occlusal dentin surface and acid etched for 20 seconds (20% phosphoric acid gel, Gluma Etch 20 Gel, Heraeus/Kulzer). After rinsing the acid etchant, an ethanol-ba...

New distributional data are reported on the rare phanaeine dung beetle, Oxysternon pteroderum Nevinson, 1892, based on five specimens recently collected between 1985 and 2010. Before the present study, Oxysternun pteroderum had been reported solely from the super-moist Atlantic coastal forests of southeastern Brazil. We now believe that the distribution of Oxysternun pteroderum follows the ripa...
