Resistance training in rodent models is widely used to investigate muscular and cardiovascular adaptations. Traditional models often attach loads to the tail. The present study aimed to develop and validate a resistance training model for rats using a pulley system combined with a load-bearing vest, allowing progressive overload without tail attachment. Spontaneously hypertensive rats were assigned to control (CTR, n = 4) or r...

Aquaculture effluents are increasingly recognized as a strategic resource for agricultural water reuse, especially in semi-arid regions, where water scarcity and fertilizer costs intensify pressure on production systems. Within a circular economy framework, these effluents may simultaneously supply water and nutrients; however, their physicochemical composition must be carefully assessed, since excessive salt loading may impai...

Over the years, urban rivers have suffered from environmental degradation due to anthropogenic activities, becoming a public concern. Thus, the objective of this study was to evaluate the spatiotemporal evolution of water quality in the Apodi-Mossoró River, in the urban section of Mossoró-RN, during the dry and rainy seasons. To this end, the physical–chemical and microbiological attributes of water samples collected at six po...

The present study investigated how dietary inclusion of solubilized mannan oligosaccharide (MOS) influences growth performance, digestive health, stress resilience, and production profitability in Pacific white shrimp (Penaeus vannamei) reared under intensive synbiotic conditions. Juveniles averaging 3.00 ± 0.04 g were stocked at 100 shrimp m−2 and fed experimental diets containing 0 (control), 1.0, 2.0, or 4.0 g kg−1 MOS for...

Infectious myonecrosis virus (IMNV) is considered one of the pathogens that most affect the production of Penaeus vannamei , causing economic losses estimated at billions of dollars. P. vannamei rearing is expanding to inland waters, which are commonly used for the farming of Macrobrachium rosenbergii , increasing the probability of exposure of this freshwater prawn to viruses often reported in penaeids, including IMNV. Theref...

The coronavirus disease-2019 (COVID-19) pandemic has affected different sectors of society, and healthcare workers have been particularly impacted. This study aimed to describe the clinical, epidemiological, and molecular characteristics of SARS-CoV-2 infections among healthcare workers in Evandro Chagas Institute, a research reference center in Brazil, from October 2020 to July 2022. 845 samples were collected from individual...
