Effect of Lactobacillus plantarum and Pseudomonas aeruginosa culture supernatants on polymorphonuclear damage and inflammatory response
(Elsevier Science, 2010-02)
In a previous study we determined that by-products of Lactobacillus plantarum inhibited pathogenicity of Pseudomonas aeruginosa and is effective in the treatment of infected wounds. This study assesses the cytotoxic activity ...
Pro-apoptotic effects of parathyroid hormone in intestinal cells
(National Research Council Canada-NRC Research Press, 2009-03-20)
Apoptosis, a form of programmed cell death, is a process fundamental to normal growth and development, immune response, tissue remodeling after injury or insult, and homeostasis of the intestinal epithelium. Recently, it ...
Galacto-oligosaccharides and lactulose as protectants against desiccation of Lactobacillus delbrueckii subsp. bulcaricus
(Wiley, 2014-10)
Lactobacillus delbrueckii subsp. bulgaricus CIDCA 333 was dehydrated on desiccators containing silica gel in the presence of 20% w/w of two types of galacto-oligosaccharides (GOS Biotempo and GOS Cup Oligo H-70®) and ...
Multicellular spheroid formation and evolutionary conserved behaviors of apple snail hemocytes in culture
(Elsevier, 2013-03)
A hemocyte primary culture system for Pomacea canaliculata in a medium mimicking hemolymphatic plasma composition was developed. Hemocytes adhered and spread onto culture dish in the first few hours after seeding but ...
Efficient Cu-catalyzed base-free C–S coupling under conventional and microwave heating. A simple access to S-heterocycles and sulfides
(Beilstein-institut, 2013-03)
S-aryl thioacetates can be prepared by reaction of inexpensive potassium thioacetate with both electron-rich and electron-poor aryl iodides under a base-free copper/ligand catalytic system. CuI as copper source affords ...
A novel indicator of karyotype evolution in the tribe Leucocoryneae (Allioideae, Amaryllidaceae)
(Springer Tokyo, 2017-10)
The tribe Leucocoryneae is taxonomically andcytogenetically complex, mainly due to its extraordinarymorphological and karyological variation. Robertsoniantranslocations had long been recognized as a central factorcontributing ...
Síntese e estereoquímica de isoxazóis espiro-tetracíclicos trifluormetil substituídos
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2017-02-23)
The present dissertation initially describes methodologies for the synthesis of five 3-(trifluoromethyl)-3,3a-dihydrospiro[chromeno[4,3-c]isoxazole-4,1'-cycloalkan]-3-ols (7) in 65 – 84 % yields, where the spirocarbocyclic ...
Mecanismo antitumoral da berberina em linhagem de células U87MG de glioblastoma multiforme
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2017-07-31)
Glioblastoma multiforme (GBM) is the most prevalent tumor among gliomas. GBM cells present high pleomorphism, with undifferentiated cells, with cellular atypia and high mitotic activity, being considered as incurable tumors ...
