1. Screening, diagnosis and management of hypothyroidism in pregnancy: Number 10 – October 2022
Key points Pregnancy places a metabolic overload on the maternal thyroid, especially in the first trimester, mainly because of the demand imposed by the conceptus. The fetal thyroid becomes functionally mature only around pregnancy week 20. Until then, the fetus depends on the transfer of maternal thyroid hormones (THs). Thyroid hormones are essential for

3. Population and reproductive parameters of the red-tailed catfish, Phractocephalus hemioliopterus (Pimelodidae: Siluriformes), from the Xingu River, Brazil
RESUMO Um estudo de campo sobre a proporção sexual, relação peso-comprimento, tamanho de primeira maturação gonadal e o período reprodutivo da pirarara, Phractocephalus hemioliopterus foi realizado na região do Médio Rio Xingu, na Amazônia oriental. Os espécimes foram coletados trimestralmente entre setembro de 2012 e janeiro de 2014, utilizando r

4. Heritability estimation and genetic correlations for mature weight, visual scores, and growth traits in Nellore cattle
ABSTRACT This study was intended to estimate the genetic associations between growth traits and visual scores with possible changes in mature weight (MW) in 397,900 Nellore animals. A bi-character analysis was performed to estimate the (co)variances and genetic parameters for MW, which comprises the following traits: conformation, finishing precocity, muscul

5. Assessment of the nitrification process in a culture of pacific white shrimp, using artificial substrate and bacterial inoculum in a biofloc technology system (BFT)
RESUMO: Litopenaeus vannamei é o camarão marinho mais cultivado em todos os tipos de sistemas, incluindo o Sistema de Tecnologia de Bioflocos (BFT). Os bioflocos são formados por microorganismos, entre estes, bactérias autotróficas que são responsáveis pelo processo de nitrificação. Este estudo teve como objetivo identificar e promover o desenvolvi

6. Sample size for the evaluation of ‘BH-65’ papaya fruits under protected cultivation
Resumo O cultivo de mamoeiro em estufa vem tornando-se, nos últimos anos, uma alternativa de cultivo em diversas partes do mundo. Objetivou-se com este trabalho determinar o tamanho de amostra para avaliar frutos maduros de mamoeiro ‘BH-65’ cultivado em estufa no sul da Espanha. Foram colhidos 26 frutos no estádio 2 de maturação, em julho de 2013, e

7. Breeding goals and economic values for Nellore cattle in a full-cycle production system
ABSTRACT. The objective of this study was to develop a bio-economic model for the estimation of economic values of economically important traits in a full-cycle beef cattle production system. The bio-economic model calculated economic values by simulating the impact of changes in the profit of the system consisting of a 1% increase in each trait of the breed

8. The influence of a large reservoir on the reproductive activity of the white piranha, Serrasalmus brandtii (Lütken, 1875) in Southeast Brazil
Resumo: Com o objetivo de avaliar a influência da barragem de Três Marias na reprodução da piranha branca, Serrasalmus brandtii, foram analisados 1569 exemplares capturados de junho de 2011 a maio de 2012 em três trechos da bacia do rio São Francisco: seção 1 = reservatório de Três Marias (RTM); seção 2 = segmento do rio São Francisco (SRF) imed

9. Are there differences in the growth adaptation processes of growing and mature organism models of short bowel syndrome?
OBJECTIVES: The purpose of this study was to present an experimental model of short bowel syndrome (SBS) in weaning rats and to compare the adaptative mechanisms of the remaining bowel in weaning rats and adult animals by means of morphometric, histologic and molecular methods. METHODS: Twenty-four weaning rats were divided into 3 groups of 8 animals, one

10. Two independent grain-length mutants mapped to a single region on the long arm of chromosome 2 in rice
ABSTRACT Grain shape in rice is a key determinant of grain appearance, yield and market value, and thus has been widely studied. Rice mutant lines with long-grain phenotypes were previously isolated from an M2 population derived from mutagenized mature pollen grains that were treated with gamma-ray irradiation for a cultivar Ma85. To understand the genetic b

11. Reproductive biology of the eyespot skate Atlantoraja cyclophora (Elasmobranchii: Arhynchobatidae) an endemic species of the Southwestern Atlantic Ocean (34ºS - 42ºS)
ABSTRACT Atlantoraja cyclophora is an endemic skate to the continental shelf of the Southwestern Atlantic Ocean (22ºS-47ºS) and a by-catch species in commercial bottom trawl fisheries. The morphometric relationships, the size at maturity and the reproductive cycle of this species were analyzed, with samples collected between 34ºS and 42ºS. The size range

12. Non-seasonal reproduction in inseminating species of Mimagoniates (Characidae, Characiformes) from southern Brazil
Abstract Some aspects of reproduction in two species of Mimagoniates, M. microlepis (Steindachner 1877) and M. rheocharis Menezes & Weitzman 1990 are herein described. Samples were taken monthly from January 1998 to February 1999 in two streams in the locality of Maquiné, Rio Grande do Sul, Brazil. Results from the analysis of hundreds of specimens of M. mi
