Simvastatin-Enriched Macro-Porous Chitosan-Calcium-Aluminate Scaffold for Mineralized Tissue Regeneration
(2020-09-04)
The present study evaluated the odontogenic potential of human dental pulp cells (HDPCs) exposed to chitosan scaffolds containing calcium aluminate (CHAlCa) associated or not with low doses of simvastatin (SV). Chitosan ...
Nanostructured titanium alloy surfaces for enhanced osteoblast response: A combination of morphology and chemistry
(2020-02-15)
This study is part of a new trend in the metallic biomaterials field that searches to use the titanium beta alloys with recognized bulk and surface properties for better biological response. Ti15Mo alloy (wt%) had it surface ...
Preparation, structural, microstructural, mechanical, and cytotoxic characterization of Ti-15Nb alloy for biomedical applications
(2020-08-01)
Titanium alloys are widely used in the biomedical field due to their excellent resistance to corrosion, high mechanical strength/density ratio, low elastic modulus, and good biocompatibility. Niobium is a β-stabilizer ...
Dehiscent organs used for defensive behavior of kamikaze termites of the genus Ruptitermes (Termitidae, Apicotermitinae) are not glands
(2016-03-01)
During Isoptera evolution, the caste of soldiers disappeared in some Apicotermitinae termites as in the Neotropical Ruptitermes. Paired dorsolateral structures located between the metathorax and abdomen of foraging workers ...
Application of natural rubber latex as scaffold for osteoblast to guided bone regeneration
(2017-10-15)
Natural rubber latex (NRL) from Hevea brasiliensis is a colloidal system composed of cis-1,4-polyisoprene. Its applications have grown due its angiogenic and wound healing activity. NRL has been used in guided bone ...
Analysis of the Virulence of an Atypical Enteropathogenic Escherichia coli Strain In Vitro and In Vivo and the Influence of Type Three Secretion System
(Hindawi Publishing Corporation, 2014-01-01)
Atypical enteropathogenic Escherichia coli (aEPEC) inject various effectors into intestinal cells through a type three secretion system (T3SS), causing attaching and effacing (A/E) lesions. We investigated the role of T3SS ...
Biological and antimicrobial properties of the association Ambroxol and a water-soluble viscous liquid as a vehicle for a tricalcium silicate-based sealer
(2021-12-01)
This study aimed to investigate the antimicrobial and biological properties of Ambroxol associated with glycerin (GLI), propylene glycol (PG), and polyethylene glycol (PEG) as a possible vehicle for an experimental tricalcium ...
Gastric cancer: Genetic and molecular [C�ncer g�strico: Alteraciones gen�ticas y moleculares]
(2011)
In this work, the genetic and molecular alterations involved in gastric carcinogenesis are shown; the affected genes are those that encoded for matrix metalloproteinases, cell growth factors and receptors, oncogenes, tumor ...
Copper source determines chemistry and topography of implant coatings to optimally couple cellular responses and antibacterial activity
(2021-01-01)
Implant-related infections at the early healing period are considered one of the main risk factors in implant failure. Designing coatings that control bacterial adhesion and have cell stimulatory behavior remains a challenging ...
Lactadherin: From a Well-Known Breast Tumor Marker to a Possible Player in Extracellular Vesicle-Mediated Cancer Progression
(2022)
Lactadherin is a secreted glycoprotein associated with the milk fat globule membrane, which is highly present in the blood and in the mammary tissue of lactating women. Several biological functions have been associated ...
