Protein intake and the use of levodopa in patients with Parkinson’s disease
(2013) [Journal article]Levodopa is the principal pharmacological treatment for Parkinson’s disease (PD); however the protein content in diet may compromise its effectiveness. The aim of this study was to investigate the relationship of protein ... -
Proteomic analysis of cattle tick rhipicephalus (Boophilus) microplus saliva: a comparison between partially and fully engorged females
(2014) [Journal article]The cattle tick Rhipicephalus (Boophilus) microplus is one of the most harmful parasites affecting bovines. Similarly to other hematophagous ectoparasites, R. microplus saliva contains a collection of bioactive compounds ... -
A proteomic insight into vitellogenesis during tick ovary maturation
(2018) [Journal article]Ticks are arthropod ectoparasites of importance for public and veterinary health. The understanding of tick oogenesis and embryogenesis could contribute to the development of novel control methods. However, to date, studies ... -
Proteomic profling of hydatid fuid from pulmonary cystic echinococcosis
(2022) [Journal article]Background: Most cystic echinococcosis cases in Southern Brazil are caused by Echinococcus granulosus and Echinococcus ortleppi. Proteomic studies of helminths have increased our knowledge about the molecular survival ... -
Protocolos laboratoriais de análise molecular para investigação de doenças genéticas
(2001) [Journal article]A aplicação da análise molecular na investigação de doenças genéticas começou a ser utilizada como avaliação rotineira em laboratórios no decorrer da última década. Mais recentemente, a identificação de mutações específicas ... -
Protocol to segment and characterize the morphometry of individual cross-sectioned striated muscle fibers from adult murine models
(2022) [Journal article]The muscle fiber morphometric analysis (MusMA) is a protocol to segment and characterize the morphometry of individual cross-sectioned striated muscle fibers. Using a semi-automated Excel spreadsheet, the protocol allows ... -
Pseudomonas aeroginosas : disseminação de resitência antimicrobiana em efluente hospitalar e água superficial
(2008) [Journal article]O objetivo deste estudo foi comparar amostras de efluente do Hospital São Vicente de Paulo com amostras de água do Rio Passo Fundo, quanto ao perfil de susceptibilidade de isolados de Pseudomonas aeruginosa, para inferir ... -
Psychotropic in the environment : risperidone residues affect the behavior of fish larvae
(2017) [Journal article]The ability to avoid and escape from predators are clearly relevant behaviors from the ecological perspective and directly interfere with the survival of organisms. Detected in the aquatic environment, risperidone can alter ... -

(2022) [Journal article]Fundamento: O pterostilbeno (PS), um composto polifenólico natural e antioxidante, surge como uma intervenção promissora para minimizar danos do infarto agudo do miocárdio (IAM). Objetivo: Este estudo teve como objetivo ... -
Pulp capping with mineral trioxide aggregate or Biodentine : a comparison of mineralized barrier formation and inflammatory and degenerative events
(2021) [Journal article]Biodentine in endodontic practice has been widely investigated, but comprehensive histological descriptions of degenerative and inflammatory responses are not covered in most of the studies that compare pulp capping ... -
Pup age and aggressive behavior in lactating rats
(2000) [Journal article]High levels of aggressive behaviors against intruders in the nest area are displayed by female rats during the first 10 days after delivery, declining thereafter to very low levels, even though lactation continues. ... -
Purification and binding analysis of the nitrogen fixation regulatory NifA protein from Azospirillum brasilense
(1998) [Journal article]NifA protein activates transcription of nitrogen fixation operons by the alternative s54 holoenzyme form of RNA polymerase. This protein binds to a well-defined upstream activator sequence (UAS) located at the -200/-100 ... -
