Comparison of intravenous and inhalation anesthesia on postoperative behavior changes in children undergoing ambulatory endoscopic procedures: A randomized clinical trial.

Background: Early and delayed behavioral changes are well recognized after anesthesia. Intravenous anesthesia may prevent emergence delirium. However, it has not been evaluated as a preventive strategy for delayed postoperative behavior changes.

Genomic insights into the diversity of non-coding RNAs in Bacillus cereus sensu lato.

Bacillus cereus sensu lato is a group of bacteria of medical and agricultural importance in different ecological niches and with controversial taxonomic relationships. Studying the composition of non-coding RNAs (ncRNAs) in several bacterial groups has been an important tool for identifying genetic information and better understanding genetic regulation towards environment adaptation. However, to date, no comparative genomics study of ncRNA has been performed in this group.

Rap-Phr Systems from Plasmids pAW63 and pHT8-1 Act Together To Regulate Sporulation in the Bacillus thuringiensis Serovar kurstaki HD73 Strain.

is a Gram-positive spore-forming bacterium pathogenic to various insect species. This property is due to the Cry toxins encoded by plasmid genes and mostly produced during sporulation. contains a remarkable number of extrachromosomal DNA molecules and a great number of plasmid genes.

Effects of copaiba oil on dermonecrosis induced by venom.

Background: Accidents caused by spiders of the genus constitute an important public health problem in Brazil. The venom of induces dermonecrosis at the bite site and systemic disease in severe cases. Traditional medicine based on plant-derived products has been proven to reduce the local effects of envenomation.

Diversity of the Rap-Phr quorum-sensing systems in the Bacillus cereus group.

Bacteria of the Bacillus cereus group colonize several ecological niches and infect different hosts. Bacillus cereus, a ubiquitous species causing food poisoning, Bacillus thuringiensis, an entomopathogen, and Bacillus anthracis, which is highly pathogenic to mammals, are the most important species of this group. These species are closely related genetically, and their specific toxins are encoded by plasmids.

Evaluation of in vitro cytotoxicity of superparamagnetic poly(thioether-ester) nanoparticles on erythrocytes, non-tumor (NIH3T3), tumor (HeLa) cells and hyperthermia studies.

Magnetic nanoparticles encapsulated in biocompatible and biodegradable polymeric matrices are promising materials for biomedical applications, such as transport of antitumoral drugs and cancer treatment by hyperthermia. In this study, biobased poly(thioether-ester), PTEe, was obtained by thiol-ene polymerization and superparamagnetic nanoparticles, MNPs, were successfully incorporated in PTEe nanoparticles by miniemulsification followed by solvent evaporation. MNPs-PTEe nanoparticles with average diameter around 150 nm presented superparamagnetic behavior as confirmed by magnetization curves analysis.

Thiol-ene miniemulsion polymerization of a biobased monomer for biomedical applications.

Herein, we present the synthesis and characterization of poly(thioether-ester) nanoparticles via thiol-ene miniemulsion polymerization using a biobased α,ω-diene diester monomer, namely dianhydro-d-glucityl diundec-10-enoate (DGU), synthesized from 10-undecenoic acid (derived from castor oil) and isosorbide (derived from starch). DGU was copolymerized with 1,4-butanedithiol by thiol-ene miniemulsion polymerization resulting in waterborne poly(thioether-ester) particles with diameter around 200nm. Polymers with number average molecular weight up to 11kDa were obtained via miniemulsion polymerization.

Effects of indirubin and isatin on cell viability, mutagenicity, genotoxicity and BAX/ERCC1 gene expression.

Context: Indigofera suffruticosa Miller (Fabaceae) and I. truxillensis Kunth produce compounds, such as isatin (ISA) and indirubin (IRN), which possess antitumour properties. Their effects in mammalian cells are still not very well understood.
