Cardiac and pulmonary alterations in symptomatic and asymptomatic dogs infected...

Fifteen symptomatic and seven asymptomatic dogs infected naturally with Leishmania chagasi were examined in order to identify the presence of parasites and changes in heart and lung. Histopathological, cytological, and immunohistochemical analyses were performed on samples of heart and lung tissues. An inflammatory reaction characterized by inflammatory mononuclear, perivascular and intermuscular infiltrates wa...

Conidiobolomicose em ovinos: reavaliação de três casos previamente diagnosticad...

Fatigue in a cohort of geriatric patients with and without Parkinson's disease

We evaluated the frequency of fatigue in geriatric patients with and without Parkinson's disease (PD) and correlated it with depression and excessive daytime sleepiness. We evaluated 100 patients from Hospital São Paulo, 50 with PD from the Neurologic Outpatient Clinic and 50 with non-neurologic diseases or oncologic diseases from the Geriatric Outpatient Clinic (controls). All patients who scored 28 or more on...

Caracterização estrutural de argilas bentoníticas nacional e importada: antes e...

Foi utilizada uma bentonita natural codificada como ASCN oriunda da Bentonit União Nordeste, PB sob forma de pó com granulometria inferior a 0,074 µm. A bentonita ASCN foi modificada organicamente através de troca iônica com o sal brometo de cetil trimetil amônio Cetremide e denominada ASCM. Para obter bentonitas organofílicas, inicialmente, dispersões aquosas de bentonita/sal Cetremide foram mantidas sob agita...

An experimental study of asphaltene particle sizes in n-heptane-toluene mixture...

The particle size of asphaltene flocculates has been the subject of many recent studies because of its importance in the control of deposition in petroleum production and processing. We measured the size of asphaltene flocculates in toluene and toluene - n-heptane mixtures, using the light-scattering technique. The asphaltenes had been extracted from Brazilian oil from the Campos Basin, according to British Sta...

Ensaio para detectar bergapteno na casca e no caule de Brosimum gaudichaudii Tr...

Plant extracts containing furocoumarins compounds were identified by using melanin producer strains of Nocardiopis sp (DAUFPE-361) and non producer strains of Streptomyces sp (DAUFPE-87). Ethanol, methanol and acetone extracted compounds from conduru (Brosimum gaudichaudii) bark and stem were evaporated and added to tubes containing ISP7 medium (tyrosine agar). This medium was inoculated with spore suspension (...
