The marine and estuarine bony fishes (Teleostei) of the Golfão Maranhense on the eastern Amazon coast, northern Brazil.

The Golfão Maranhense is an extensive estuarine complex that provides nursery grounds and other habitats for several fish species, as well as a wealth of resources for the coastal and estuarine artisanal fisheries of the Maranhão state, in northern Brazil. The present study provides a comprehensive inventory of marine and estuarine teleost fishes of the Golfão Maranhense based on field samplings, analyses of voucher specimens from local collections and literature data. This inventory presents a total of 163 species of teleosts belonging to 107 genera, 57 families and 27 orders.

Methionine Supplementation of Maternal Diet Improves Hatching Traits, Initial Development, and Performance in Japanese Quail Fed Different Levels of Methionine During Growth.

This study examined the effects of dietary levels of methionine on lipid and intestinal metabolism in Japanese quail hens and their progeny. The experiment was conducted according to a 3 × 3 factorial design, with three maternal and three progeny diets, as follows: low-methionine (LMET), recommended methionine (MET), and high-methionine (HMET). Methionine supplementation improved reproductive performance during laying (p < 0.

Transcriptomic analysis of heifers according to antral follicle count.

While antral follicle count (AFC) has been associated with higher pregnancy rates, at present, our understanding of it as a reproductive parameter remains incomplete. This study aimed to characterize gene expression profile of oocytes from crossbred Bos taurus x Bos indicus heifers with high and low AFCs. Crossbred Nelore-Angus heifers (n = 50) with a mean (SD) age of 9.

Characterization of fillets and skins from two varieties of genetically improved farmed Nile tilapia (Oreochromis niloticus).

Genetically improved farmed tilapia (GIFT) is a strain of Nile tilapia (Oreochromis niloticus) developed for improved production and commercial parameters. Skin color, one of the characteristics distinguishing tilapia varieties, is an important phenotypic trait associated with qualitative and productive performance. This study aimed to assess fillet and skin characteristics in GIFT Nile tilapia with black and red skin phenotypes.

The Cell Cycle Regulatory Proteins p16, CDK4, and PTEN Are Unsuitable as Biomarkers in Oral Melanocytic Lesions.

Background: Melanocytic neoplasms are rare in the oral cavity and represent a diagnostic challenge due to the overlap between benign and malignant lesions. However, their pathogenesis is not fully elucidated. The aim of this study was to evaluate the expression of the cell cycle-related proteins p16, CDK4, and PTEN in oral melanocytic nevi and melanomas.
