Clinical and laboratory findings of hookworms ( spp.) in naturally infected adult dogs.

Intestinal parasites of the genus are the most prevalent in coproparasitological examinations and necropsies of dogs in Brazil. Although adult dogs often remain asymptomatic when infected, there is limited published information concerning the laboratory and clinical findings and severity of infection in symptomatic adult dogs. Therefore, this study aimed to characterize the clinical and laboratory findings of adult -infected dogs.

Chemical and in vivo analyses of calcium silicate-based materials in bone and connective tissues.

Aim: Calcium silicate-based cements have been widely used in dentistry mainly due to their physicochemical and biological properties. Commercially available materials use radiopacifiers containing metals (bismuth, tantalum, tungsten and/or zirconium). To investigate volumetric changes, in vivo biocompatibility and systemic migration from eight commercially available materials, including powder/liquid and 'ready-to-use' presentations.

Rapid Parallel Adaptation in Distinct Invasions of Ambrosia Artemisiifolia Is Driven by Large-Effect Structural Variants.

When introduced to multiple distinct ranges, invasive species provide a compelling natural experiment for understanding the repeatability of adaptation. Ambrosia artemisiifolia is an invasive, noxious weed, and chief cause of hay fever. Leveraging over 400 whole-genome sequences spanning the native-range in North America and 2 invasions in Europe and Australia, we inferred demographically distinct invasion histories on each continent.

Wildfire ashes: evaluating threats on the Pantanal wetland reserve (Mato Grosso, Brazil) using ecotoxicological tests.

In 2020, the largest continuous wetland area on the planet, the Brazilian Pantanal, experienced an unprecedented fire that affected the entire ecosystem. Our goal was to elucidate the effects of ash presence following the fire events. We quantified the impact of ashes, collected in four Conservation Units, on soil, water, and atmosphere.

Assessing reagents and techniques for identifying RhCE variants in routine serological testing.

Background And Objectives: Identifying RhCE variants is essential to prevent alloimmunization and manage complex cases. Unfortunately, these variants are often only detected after antibody formation, as they may go unnoticed in serological tests. This study aimed to assess monoclonal antisera using various methodologies to define the reactivity patterns of some variants by variable expression of RhCE antigens.
