This cross-sectional study is aimed to assess the consistency and reliability of the Brazilian Portuguese Version of the Mini-Sleep Questionnaire (MSQ-BR). Self-administered(More)
The feasibility of in vitro mature mouse hepatocyte labeling with a novel iron oxide particle was assessed and the ability of 1.5-T magnetic resonance imaging (MRI) to track labeled mouse hepatocytes in syngenic recipient livers following intraportal cell transplantation was tested. Mouse hepatocytes were incubated with anionic iron oxide nanoparticles at(More)
The beta-blocker DL-1-(2-nitro-3-methylphenoxy)-3-tert-butylaminopropan-2-ol (ZAMI 1305), hepatocarcinogenic to the female rat, and the non-oncogenic beta-blockers DL-1-(2-nitro-5-methylphenoxy)-3-tert-butylaminopropan-2-ol (ZAMI 1327), DL-propranolol, and DL-atenolol were studied for their capacity to interfere with hepatic DNA and RNA synthesis.

Aluminum Chloride Phthalocyanine (AlPcCl) can be used as a photosensitizer (PS) for Photodynamic Inactivation of Microorganisms (PDI). The AlPcCl showed favorable characteristics for PDI due to high quantum yield of singlet oxygen (ΦΔ ) and photostability. Physicochemical properties and photodynamic inactivation of AlPcCl incorporated in polymeric micelles(More)
