Comparative ovarian morphophysiology of rats and Zebrafish after exposure to nandrolone decanoate.

This study aimed to compare the effects of nandrolone decanoate on the morphology and physiology of ovarian tissues in two experimental models, Zebrafish and rats, after in vitro cultivation. A total of 136 animals were used ( rats, n=36, and Zebrafish, n=100). In both experiments, the animals were divided into two groups (Control and Deca) and were exposed to nandrolone decanoate for seven weeks.

The burden of dengue in South American countries, 1990-2019: Estimates from the Global Burden of Disease study 2019.

Objectives: To describe the main dengue metrics generated by the Global Burden of Disease (GBD) Study 2019 for South American countries between 1990 and 2019.

Study Design: A descriptive study was carried out using the metrics obtained by the GBD Study 2019.

Methods: The metrics of incidence, years of life lost due to premature death (YLLs), years lived with disability (YLDs) and disability-adjusted life years (DALYs) were evaluated, grouped by sex and country, between 1990 and 2019.

Lack of TLR9 exacerbates ocular impairment and visual loss during systemic Cryptococcus gattii infection.

Cryptococcus gattii is a saprophytic basidiomycete that grows in the environment and can cause systemic cryptococcosis. Ocular cryptococcosis causes blindness and is commonly associated with central nervous system (CNS) infection. Toll-like receptor 9 (TLR9) can control cryptococcosis and another mycosis.

Protective Effects of Spondias mombin L. Juice Alone or in Combination With Lactobacillus acidophilus in 5-Fluorouracil-Induced Experimental Intestinal Mucositis.

Background: Evaluate the impact of Spondias mombin L. juice (SM), alone and in combination with Lactobacillus acidophilus, in an experimental model of intestinal mucositis.

Methods: Swiss mice were orally administered with saline, SM, or SM combined with L.

Multiple Tolerization Subtractive Immunization in the Obtention of Specific Monoclonal Antibodies Against .

Paracoccidioidomycosis (PCM) is a chronic endemic mycosis in Latin America, predominantly caused by (Pb18) and (Pl01). Diagnosing PCM is challenging due to species-specific antigenic differences, therefore new biomarkers for accurate and rapid detection are needed. This study explores multiple tolerization subtractive immunization (MTSI) to generate monoclonal antibodies against rare or weakly expressed epitopes of Pb18 and Pl01, potentially improving PCM diagnosis.
