objective: etching of enamel and dentin is an important step in restoration of teeth with composite resin ensuring the retention of restoration and decreasing microleakage. this in vitro study sought to compare the effects of kimiya and etch-rite acid etchants on the microleakage of composite restorations.   methods: this experimental study was conducted on 30 sound human molar teeth. class v c...

Unlike other arboreal monocotyledons, the secondary growth of palms has for the past 100 years been described as diffuse. Solely cell enlargement and random parenchyma divisions, without the activity of a meristem, characterize such growth. Some previous works of the early 20th century have, however, mentioned the presence of a secondary meristem in the stems of palms, but this information was ...

Among the interesting studies published in this issue of the AABC that should be highlighted is the work on the primary and secondary thickening in the stem of a monocotyledon species by Marina B. Cattai and Nanuza L. de Menezes from the Instituto de Biociências of the Universidade de São Paulo. There is still great discussion over how this thickening occurs in this major group of flowering pla...

OBJECTIVE The present study was undertaken to elucidate the effect of the ACE inhibitor and the angiotensin II type 1 (AT1) receptor antagonist in combination on neointimal hyperplasia after balloon injury. METHODS AND RESULTS Temocapril (an ACE inhibitor), CS-866 (an AT1 receptor antagonist), or their combination was given orally to rats, and their effects were compared on vascular hyperplas...

mal thickness of 41.1 μm, whereas sites treated with vehicle alone measured an average of 22.6 μm, indicating a significant difference in epidermal thickness between aTd-treated groups and vehicle controls, Po0.001 (Mann– Whitney test, Figure 1e and f). In summary, we have demonstrated in vivo capabilities of aTds to initiate protect and repair response in non-UVexposed guinea pig skin. By mimi...
