Methods: Thirty extracted human pre-molars were restored by amalgam. A simulated defect was prepared and assigned to two treatment groups (n=15): G1 repaired by amalgam (Permite C-SDI); G2 repaired by bonded amalgam (Caulk 34% Tooth Conditioner Gel – Dentsply + Prime & Bond 2.1 – Dentsply + Permite CSDI). The teeth were immersed in a 50% silver nitrate solution, thermocycled and then, sectioned...

Two-dimensional analyses of the histopathological aspect of carious lesions present bias that may compromise the scientific value of studies. In this paper, the authors present a new three-dimensional technique for the histopathological analysis of carious lesions. It consists in the dissection of the affected areas under the stereomicroscope, utilizing refrigerated dental burs, without any los...

A number of genera of Histiostomatidae inhabit phytotelmata, being found fully submerged and filtering organic matter from the fluid. One such phytotelm habitat is the fluid-filled pitchers of species of Nepenthes, a carnivorous plant genus widely distributed in the Old World tropics. As in most histiostomatid species, males of Nepenthes-inhabiting mites seek out tritonymphal females and guard ...

BACKGROUND Zebrafish (Danio rerio), due to its optical accessibility and similarity to human, has emerged as model organism for cardiac research. Although various methods have been developed to assess cardiac functions in zebrafish embryos, there lacks a method to assess heartbeat regularity in blood vessels. Heartbeat regularity is an important parameter for cardiac function and is associated ...

AIM To evaluate and compare the shear bond strength of metal brackets bonded to ceramic surfaces using different conditioning methods and to assess the site of bond failure after debonding. MATERIALS AND METHODS A total of 70 ceramic surfaces were produced with uniform shape, size and composition. The samples were divided into 7 groups (each of 10 samples). Group 1 was the control group (untr...

Anapidae are small-sized (~ 3 mm), three-clawed, haplogyne spiders with six or eight eyes situated on an elevated ocular region and an anterior labral spur. The family currently contains 38 genera and 153 species worldwide (Platnick 2013, Lin, Li & Jäger, 2013). Nine species belonging to six genera have been recorded from China (Oi, 1960; Brignoli 1981; Zhang & Chen, 1994; Wunderlich & Song, 19...
