Toxicity assessment of effluent from a potato-processing industry in Cyprinus carpio.

Potato (Solanum tuberosum) cultivation faces the challenge of excessive pesticide use. During processing, the disposal of large volumes of contaminated water into water bodies can result in severe environmental damage, such as fish deaths. This study aimed to evaluate the toxicological effects of chemical compounds present in the effluent from a potato-processing industry using the test organism Cyprinus carpio.

The combined effect of environmentally relevant doses of glyphosate and high temperature: An integrated and multibiomarker approach to delineate redox status and behavior in Danio rerio.

Glyphosate, a pesticide commonly found in aquatic ecosystems, affects this habitat and nontarget organisms such as fish. The increase in water temperature, linked to factors such as climate change, poses a considerable threat. Despite extensive ecotoxicological research, we still do not know the real individual and specific consequences of continued exposure to glyphosate and high temperatures, simulating a scenario where the aquatic environment remains contaminated and temperatures continue to rise.

Fifty-five multiparous purebred Wagyu cows underwent a Fixed-Time Artificial Insemination (FTAI) protocol using semen from a bull randomly selected from five bulls representing three distinct genetic lines. Following birth, we recorded the calves' gender, weight, and gestation length.

Stereotactic radiotherapy as a valuable therapeutic procedure for controlling aldosterone-secreting adrenocortical carcinoma.

Aldosterone-secreting adrenocortical carcinomas (ACCs) are rare and usually present as large tumors. The only potentially curative treatment for ACC is surgical resection. However, surgery may be unfeasible in some patients who have multiple comorbidities or decline the procedure.

The microbiome effect on the female reproductive performance.

The female reproductive function is coordinated by the endocrine system driven by the hypothalamic-pituitary-gonadal (HPG) axis. While not directly part of the female reproductive system, the gut microbiome plays a crucial role in overall health, including reproductive health. The gut microbiome communicates bidirectionally with the brain via the gut-brain axis, influencing stress levels, mood, and hormonal balance, which can impact reproductive health and fertility.

Highly efficient mobility, separation and charge transfer in black SnO-TiO structures with co-catalysts: the key step for the photocatalytic hydrogen evolution.

In this study, our goal was to prospect lipase and assess its efficacy as a biocatalyst for ethyl oleate synthesis.

as a suitable model to evaluate the toxicity of water from Rolante River, southern Brazil.

Urbanization and agricultural activities increased environmental contaminants. Integrated analysis of water parameters and bioassays represents an essential approach to evaluating aquatic resource quality. This study aimed to assess water quality by microbiological and physicochemical parameters as well as the toxicological effects of water samples on the Ames test and model.

Efficiency of home water filters on pesticide removal from drinking water.

Water pollution via natural and anthropogenic activities has become a global problem, which can lead to short and long-term impacts on humans' health and the ecosystems. Substantial amounts of individual or mixtures of organic pollutants move into the surface water via point and non-point source contamination. Some of these compounds are known to be toxic and difficult to remove from water sources, thus affecting their quality.

Rapid response of a public health reference laboratory to the COVID-19 pandemic.

Brazil was one of the most affected countries by the COVID-19 pandemic. Instituto Adolfo Lutz (IAL) is the reference laboratory for COVID-19 in São Paulo, the most populous state in Brazil. In April 2020, a secondary diagnostic pole named IAL-2 was created to enhance IAL's capacity for COVID-19 diagnosis.

Epilithic biofilms as a discriminating matrix for long-term and growing season pesticide contamination in the aquatic environment: Emphasis on glyphosate and metabolite AMPA.

The indiscriminate use of pesticides represents high ecological risk in aquatic systems. Recently, the inclusion of epilithic biofilms as a reactive matrix has shown potential in diagnosing the health of water resources. The objective of this study was to use multiple matrices (water, suspended sediments, and biofilms) to discriminate contamination degrees in catchments with long and recent history of intensive pesticide use and to monitor growing season pesticides transfer to watercourses.

Evaluation of sperm and hormonal assessments in Wagyu, Nellore, and Angus bulls.

Wagyu bulls are known to have a highly exacerbated libido, as shown by the intense sexual interest of young calves. Therefore we believe that Wagyu male animals have specialized Sertoli and Leydig cells that are directly involved with the sexual precocity in this breed as mature bulls have a small scrotal circumference. This study aimed to evaluate whether there were differences in the hormone and sperm characteristics of Wagyu bulls compared with the same characteristics of subspecies and sires.

Association between anti-Müllerian hormone levels and reproductive parameters in Wagyu cattle raised in Brazil.

The production of embryos has sped up the dissemination of superior genetic material. However, the variation among the cattle response to oocyte and embryo production is a challenging factor. This variation is even higher in the Wagyu cattle as the breed has a small effective population size.

An enriched maternal environment and stereotypies of sows differentially affect the neuro-epigenome of brain regions related to emotionality in their piglets.

Epigenetic mechanisms are important modulators of neurodevelopmental outcomes in the offspring of animals challenged during pregnancy. Pregnant sows living in a confined environment are challenged with stress and lack of stimulation which may result in the expression of stereotypies (repetitive behaviours without an apparent function). Little attention has been devoted to the postnatal effects of maternal stereotypies in the offspring.
