Effects of light-curing time on the cytotoxicity of a restorative composite resin on odontoblast-like cells
(Faculdade De Odontologia De Bauru - USP, 2010)
This in vitro study evaluated the cytotoxicity of an experimental restorative composite resin subjected to different light-curing regimens. METHODS: Forty round-shaped specimens were prepared and randomly assigned to four ...

Cell death in ovarioles causes permanent sterility in Frieseomelitta varia worker bees
(1999-12-01)
Frieseomelitta varia worker bees do not lay eggs even when living in queenless colonies, a condition that favors ovary development and oviposition in the majority of highly social bees. The permanent sterility of these ...
T-cell recognition is shaped by epitope sequence conservation in the host proteome and microbiome
(Wiley Blackwell Publishing, Inc, 2016-05)
Several mechanisms exist to avoid or suppress inflammatory T-cell immune responses that could prove harmful to the host due to targeting self-antigens or commensal microbes. We hypothesized that these mechanisms could ...
Establishment and Characterization of Canine Mammary Gland Carcinoma Cell Lines With Vasculogenic Mimicry Ability in vitro and in vivo
(2020-10-27)
Mammary tumors affect intact and elderly female dogs, and almost 50% of these cases are malignant. Cell culture offers a promising preclinical model to study this disease and creates the opportunity to deposit cell lines ...
Cdc42p controls yeast-cell shape and virulence of Paracoccidioides brasiliensis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
Paracoccidioides brasiliensis is characterized by a multiple budding phenotype and a polymorphic cell growth, leading to the formation of cells with extreme variations in shape and size. Since Cdc42 is a pivotal molecule ...
New morphological data on fat bodies of semi-engorged females of Amblyomma cajennense (Acari : Ixodidae)
(Pergamon-Elsevier B.V. Ltd, 2008-10-01)
The present ultramorphological, histological and ultrastructural study on the fat body of semi-engorged females of Amblyomma cajennense revealed that this tissue is diffuse and consists of strands of cells surrounding the ...
Local Electrochemical Investigation of Single Grains of Polycrystalline Cu-16%Zn-8%Al Alloy
(Soc Brasileira Quimica, 2011-11-01)
Local electrochemical studies of single grains of a polycrystalline Cu-16%Zn-8%Al alloy were investigated in borate buffer solution (pH 8.4) by means of microelectrochemical technique. The grain orientations, which were ...
Steel beam–column connection using copper-based shape memory alloy dampers
(ELSEVIER SCI LTD, 2008-04)
This study presents the details of an experimental investigation on a prototype partially restrained connection using copper-based shape memory
alloy (SMA) bars. The proposed configuration consists of an end-plate connection ...
Biosynthesis of plant cell walls
(Facultad de Agronomía e Ingeniería Forestal, Pontificia Universidad Católica de Chile ., 2006-09)
The
cell wall plays a major role in determining the expansion, growth and shape of plant cells, and
thus of the plant itself. Additionally, cell wall breakdown products are used as developmental
signals. Moreover, the ...
