Susceptibility of Tambaqui () to Nile Tilapia-Derived and .

Nile tilapia () and tambaqui () are the two most produced freshwater fishes in Brazil. This study investigated the potential pathogenicity of and , previously isolated from diseased Nile tilapia, to tambaqui. Experimental infection trials were conducted in juvenile tambaqui at a dose of approximately 10 CFU fish, assessing clinical signs, mortality, bacterial recovery, and histopathological changes.

Screening of Lipid-Reducing Activity and Cytotoxicity of the Exometabolome from Cyanobacteria.

Cyanobacteria are rich producers of secondary metabolites, excreting some of these to the culture media. However, the exometabolome of cyanobacteria has been poorly studied, and few studies have dwelled on its characterization and bioactivity assessment. In this work, exometabolomes of 56 cyanobacterial strains were characterized by HR-ESI-LC-MS/MS.

[Are there differences between men and women with respect to the factors associated with calcium intake?].

The scope of this article is to verify if there are differences in factors associated with calcium intake between men and women. It is based on a study conducted with data from a health survey in a sample of 1641 individuals aged 20 years or more living in the urban area of the city of Campinas, in the State of São Paulo. Calcium intake was obtained from a 24-hour recall (24hr recall method) and analyzed according to sociodemographic variables, health behavior, frequency of meals and body mass index (BMI).

Oral Administration of Kaempferol Isolated from Baccharis Mattogrosensis Enables In Vivo Activity Against Schistosoma Mansoni.

Baccharis mattogrosensis is a species from Asteraceae which has been used in Brazilian folk medicine to treatment of several illnesses, including those caused by parasites. In the present work, the MeOH extract of aerial parts of B. mattogrosensis was subjected to chromatographic fractionation to afford three flavonoids: apigenin (1), quercetin (2), and kaempferol (3) as well as a mixture three chlorogenic acids: 3,4-O-dicaffeoylquinic (4), 3,5-O-dicaffeoylquinic (5), and 4,5-O-dicaffeoylquinic (6) acids.

Condom use across casual and committed relationships: The role of relationship characteristics.

Background: While the existence of a complex variety of casual sexual relationships (CSRs) has been acknowledged, studies rarely describe the prevalence of condom use across these relationships or how their hybrid nature, specifically relationship characteristics, affect condom use. This study aims to describe condom use within committed relationships and various types of casual sexual relationships (CSRs), examining the influence of relationship characteristics on condom use among culturally validated relationship types (committed, friends with benefits, hookups, booty call).

Methods: Emerging adults (N = 728, 18-29 years, M = 22.
