1. A Systematic Pipeline to Enhance the Fecal Metabolome Coverage by LC-HRMS
The comprehended knowledge of the metabolic profile of the fecal matter has been recognized as an important point for understanding metabolic changes in the human systemic metabolism and it can provide precious information about host-gut microbiota interactions. However, few analytical strategies have been addressed for a broad analysis of metabolites with d

2. The role of the microbiota-gut-brain axis in neuropsychiatric disorders
The microbiota-gut-brain axis is a bidirectional signaling mechanism between the gastrointestinal tract and the central nervous system. The complexity of the intestinal ecosystem is extraordinary; it comprises more than 100 trillion microbial cells that inhabit the small and large intestine, and this interaction between microbiota and intestinal epithelium c

4. MONITORING OF PROGESTERONE AND ESTRONE FECAL METABOLITES THROUGHOUT GESTATION IN EWES
Resumo O objetivo deste estudo foi monitorar os níveis de metabólitos fecais de progesterona e estrona ao longo da gestação em ovelhas, correlacionando-os com os níveis séricos desses hormônios esteroides. Assim, amostras de fezes e sangue foram colhidas de cinco ovelhas no período pré-cobertura e durante a gestação, até duas semanas após o part

5. Influence of fermented fish meal supplementation on growth performance, blood metabolites, and fecal microflora of weaning pigs
ABSTRACT This study was conducted to estimate the effect of dietary supplementation with fermented fish meal on growth performance, blood metabolites, and fecal microflora in weaning pigs. A total of 180 weaned pigs ((Landrace ×Yorkshire) × Duroc; with average body weight of 6.0 kg) were randomly distributed among three dietary treatments (0, 0.2, and 0.5%

6. Estratégias e fisiologia do consumo e digestão de esponjas (Porifera) por Echinaster brasiliensis (Echinodermata: Asteroidea) / Strategies and physiology of the consumption and digestion of sponges (Porifera) by Echinaster brasiliensis (Echinodermata: Asteroidea)
Sponges are sessile and have a skeleton made of microscopic inorganic elements (spicules), collagen fibers and/or combinations of these two components. Although without clear physical defenses such as shells or spines, they are not preyed upon, and this is attributed mainly to the presence of active secondary metabolites. Recently, a role of skeletal compone

7. Profile study of cortisol and testosterone fecal and urine hormonal metabolites in Black-tufted marmoset males (Callithrix penicillata, Geoffroy, 1812) submitted to physical restraint / Estudo dos perfis de metabólitos hormonais urinários e fecais de cortisol e testosterona em machos de sagui-de-tufos-pretos (Callithrix penicillata, Geoffroy, 1812) submetidos à contenção física
A manutenção de animais em zoológicos, criadouros e centros de reprodução tem como objetivo auxiliar os programas de conservação in situ e ex situ, além de contribuir para os programas de educação ambiental. A cada dia, torna-se mais clara a importância do bem-estar dos animais cativos, e a redução do estresse é fundamental neste contexto. A co

8. Estudo do ciclo ovariano de sagüi-de-tufos-pretos (Callithrix penicillata, GEOFFROY, 1812) com o uso de métodos não-invasivos: extração e mensuração de metabólitos fecais de estradiol e progesterona / Study of the Black-tufted-marmosets (Callithrix penicillata) ovarian cycle with the use of non-invasive methods: extraction and measurement of estrogen and progesterone fecal metabolites
Este trabalho teve por objetivo descrever os perfis hormonais do ciclo ovariano de cinco exemplares adultos de C. penicillata, mantidas no Parque Municipal Quinzinho de Barros em Sorocaba, SP. As amostras de fezes foram colhidas diariamente, sempre pela manhã, durante três meses e mantidas congeladas até o processamento laboratorial. Após a extração co

9. INVESTIGATIONS ON BIOLOGICAL INDICATORS FOR FEED EFFICIENCY IN CATTLE
This thesis aimed to identify potential indicators for feed efficiency and also better understand the biological factors influencing the efficiency of feed utilization by cattle. The growing focus of the beef industry on feed efficiency has resulted in the demand for more reliable low-cost alternatives for predicting feed efficiency. Many researchers have in

10. Captivity behavior and evaluation of two environmental enrichment procedures for ocelots (Leopardus pardalis) / Comportamento em cativeiro e teste da eficácia de técnicas de enriquecimento ambiental (físico e alimentar) para jaguatiricas (Leopardus pardalis)
Brazil exhibits a large variety of wild cat species, most of which under the threat of extinction. Reproduction in captivity is an essential tool for the conservation of these species, and it is directly linked to animal welfare. This project aimed the study of the behavior of the ocelot (a small-sized American wild cat; Leopardus pardalis under captivity, l

11. Non-invasive endocrine monitoring using fecal steroid analysis: opportunities and challenges
During the past two decades, techniques for the non-invasive analysis of fecal steroid metabolites (estrogen, androgen, progestagen and glucocorticoid metabolites) have been developed. These techniques have been used for research with mammals, birds, reptiles, and to a lesser extent in fish; species studied included domestic and laboratory animals, as well a

12. Fecal estradiol and progesterone metabolite levels in the three-toed sloth (Bradypus variegatus)
The present study was carried out to assess the possibility of measuring fecal steroid hormone metabolites as a noninvasive technique for monitoring reproductive function in the three-toed sloth, Bradypus variegatus. Levels of the estradiol (E2) and progesterone (P4) metabolites were measured by radioimmunoassay in fecal samples collected over 12 weeks from
