Toxicon

March 2024

Programa de Pós-graduação em Ciências Animais nos Trópicos, Universidade Federal da Bahia (UFBA), Salvador, Bahia, Brazil.

Leucaena leucocephala poisoning is reported in horses in different Brazilian regions. The poisoning occurred one month after the horses were introduced into paddocks invaded by the plant or after 10 days of consuming cut Leucaena administered as the only food. Affected horses showed moderate to severe hair loss on the mane and tail, orthokeratotic hyperkeratosis with marked follicular telogenization, and hyperplasia of thyroid follicular cells.

No-tillage cover crops contribute to better soil quality, being able to replace mechanized tillage management. This observation can only be made after several years of adopting conservationist practices and through research on soil-plant relationships. The objective of the research was to verify the relationship between the production components, physiological, root development, and physical-hydric properties of the soil in the yield of soybean grown in succession to different cover crops or with soil chiseling.

Neurological Infection, Kynurenine Pathway, and Parasitic Infection by .

Front Immunol

February 2022

Laboratory of Biochemistry and Veterinary Immunology, Center of Agrarian, Environmental and Biological Sciences, Federal University of Recôncavo of Bahia (UFRB), Cruz das Almas, Brazil.

Article Synopsis
  • Neuroinflammation is a key focus in neuroscience, common in nearly all neurological diseases, as it serves to protect the nervous system but can inadvertently cause harm.
  • The inflammatory response can vary from neuroprotective to neurotoxic depending on the nature of the insult and the type of glial cells involved, with multiple pathways and bioactive compounds activated during the process.
  • The kynurenine pathway, which breaks down tryptophan, is particularly significant, playing roles in immune regulation and neurotoxicity, making parasitic infections a useful model for studying its impact on neuroinflammatory responses.

What is the future of Periodontal Medicine?

Braz Oral Res

October 2021

Universidade Federal do Ceará - UFC, School of Dentistry, Department of Dentistry, Sobral, CE, Brazil.

In the last five decades, considerable progress has been made towards understanding the etiology and pathogenesis of periodontal diseases and their interactions with the host. The impact of an individual periodontal condition on systemic homeostasis became more evident because of this knowledge and prompted advances in studies that associate periodontitis with systemic diseases and conditions. The term Periodontal Medicine describes how periodontal infection/inflammation can affect extraoral health.

Chitosan, derived from chitin, is a biopolymer consisting of arbitrarily distributed β-(1-4)-linked D-glucosamine and N-acetyl-D-glucosamine that exhibits outstanding properties- biocompatibility, biodegradability, non-toxicity, antibacterial activity, the capacity to form films, and chelating of metal ions. Most of these peculiar properties are attributed to the presence of free protonable amino groups along the chitosan backbone, which also gives it solubility in acidic conditions. Moreover, this biopolymer can also be physically modified, thereby presenting a variety of forms to be developed.

Objectives were to evaluate effects of a smaller than typically used dose of equine chorionic gonadotropin (eCG) during a fixed-time artificial insemination (FTAI) treatment regimen. Transrectal ultrasonic (US) examinations were conducted on dairy cows on Day 0 (D0) and the treatment regimen was initiated with administrations of an intravaginal progesterone (P) implant, estradiol benzoate (im), and prostaglandin F (PGF im). On D8, the P implant was removed and PGF and estradiol cypionate were administered to all animals.
