Study tested the toxicity of Goldenberry extract by in vivo and in vitro assays. The compound showed toxicity in mammary tumor cells. The work serves as a starting point for further research in the treatment of cancer involving natural compounds, as the formulation associated with Physalis extract showed toxicity against this cell type. … Read More →

A study of a female Dachshund breed with altered neurological signs resulted in a diagnosis of multifocal lesion. At necropsy, it was found to be a rare tumor in the retrobulbar region, affecting only 3% of dogs. The research draws attention to the importance of including this possibility of pathology during diagnosis. … Read More →

The capacity of dietary fibers to improve digestion and metabolism is directly linked to the physico-chemical properties of these elements, such as water retention capacity, oil binding and fiber cations. The research found that it is possible to improve the functional characteristics of the fibers, through methods such as micronisation and extrusion. … Read More →

The expansion of aquaculture increasingly exposes fish to diseases such as aeromonose caused by the bacteria Aeromonas hydrophila. To treat this bacterial infection, researchers tested the antimicrobial activity of the essential oil extracted from the Lippia origanoides plant. Results were obtained by an in vivo assay with 120 fish. … Read More →

Young buffalo can become infected and develop diarrhea by the action of Escherichia coli, same bacterial agent found in diarrheic bovine calves. However, other pathotypes and toxins appear to be present in these animals. This study found a large number of STEC, NTEC and EAST-1 toxin in E. coli strains isolated from feces of buffaloes, those associated with diarrheagenic E. coli. … Read More →

Compounds with toxic potential, such as the carbonyls and furfuryl alcohol, can be found in sparkling wines due to environmental contamination of the grapes or chemical reactions during the winemaking process. In this study, researchers evaluated the amount of these compounds in sparkling wines and the risk that their consumption presents to health. … Read More →

In soybean culture, the length of the hypocotyl is one of the factors that evidences the genetic variability of these cultivars. This study evaluated the length of the hypocotyl of soybean crop over several planting seasons, identifying cultivars of predictable and stable behavior in relation to this factor. … Read More →

Although there is growing concern about animal welfare, procedures that cause pain and suffering in animals are still frequently performed by farmers, such as tail docking in sheep. This research collected the opinion of sheep breeders on tail docking to study the real need for this practice. … Read More →

Native fruit of the Brazilian caatinga, the Umbu has a great socioeconomic importance for family farmers and microenterprises of the producing region. It has been transformed into different products like jellies, sweets, pulps and juices. Researchers performed an X-ray of the fruit and observed that it contains nutrients and compounds with bioactive potential in its seed and peel as well as their edible part. … Read More →

Fixed-time artificial insemination can be an efficient technology to optimize swine production processes by defining the best time to perform a single artificial insemination. Still, some limitations of this biotechnology need to be considered by producers. In this literature review, researchers analyze the latest protocols for fixed-time artificial insemination in swine production, pointing out its advantages and limitations. … Read More →
