Journal ArticleDOI

TL;DR: This data, combined with N =36 additional published sequences demonstrate that (i) N. ceranae most likely jumped host to A. mellifera, probably within the last decade, (ii) that host colonies and individuals may be co-infected by both microsporidia species, and that N. Ceranae is now a parasite of A. Mellifera across most of the world.
Journal ArticleDOI
Origin and Chemical Variation of Brazilian Propolis.
TL;DR: Propolis research has uncovered potentialities of substances previously isolated from plants and has detected constituents of plant origin that would hardly be known otherwise.
Journal ArticleDOI
Cytotoxic, hepatoprotective and free radical scavenging effects of propolis from Brazil, Peru, the Netherlands and China.
Arjun H. Banskota,Yasuhiro Tezuka,I K Adnyana,Kiyoshi Midorikawa,Katsumichi Matsushige,Dejair Message,Alfredo A. G. Huertas,Shigetoshi Kadota +7 more
TL;DR: The result of hepatoprotective activity of Brazilian propolis on D-galactosamine (D-GalN)/tumor necrosis factor-alpha (TNF-alpha)-induced cell death in primary cultured mouse hepatocytes were found in accordance with the grade set up by beekeepers in Brazil.
Journal ArticleDOI
Seasonal variation, chemical composition and antioxidant activity of Brazilian propolis samples.
Érica Weinstein Teixeira,Dejair Message,Giuseppina Negri,Antonio Salatino,Paulo César Stringheta +4 more
TL;DR: No correlation was observed between antioxidant activity and either total phenolic contents or contents of artepillin C and other phenolic substances, as assayed by CG/MS analysis.
Journal ArticleDOI
Plant Origin of Green Propolis: Bee Behavior, Plant Anatomy and Chemistry.
Érica Weinstein Teixeira,Giuseppina Negri,Renata Maria Strozi Alves Meira,Dejair Message,Antonio Salatino +4 more
TL;DR: The present work aimed to observe the collecting behavior of bees, to test the efficacy of histological analysis in studies of propolis botanical origin and to compare the chemistries of alecrim apices, resin masses and green propolis.
