Uruguay has beef production as one of its most important economic activities. The quality of this meat can be affected by peculiarities of the animals’ production system, such as their food for example. The Longissimus Dorsi muscle, when tested in three different food systems, also showed differences in its quality. … Read More →

Infrared methods are often used in science. To determine the quality of soil fertilization, clay and soil organic matter (MOS) are essential components. For the analysis of these components, the use of the analytical technique of near infrared spectroscopy (Near Infrared Spectroscopy – NIRS) presents a sustainable alternative. … Read More →

The vibration produced by tractor operation has negative effects on the health of the operators of these agricultural machines. To evaluate the transmissibility of vibrations, a research presents an innovative method that allows to observe the influence of tractor-coupled agricultural equipment on the operator’s whole body vibrations. … Read More →

Research examines the feasibility of digital image processing in determining seed vigor through the method of analyzing plant biophysical characteristics. The results show that the determination of leaf length and seedling area obtained by digital image processing is effective to evaluate the vigor of rice seeds. … Read More →

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 →
