Genetic analyses have the potential to elucidate many aspects of juvenile green turtle (Chelonia mydas) biology and ecology, such as foraging ground composition, hatchling dispersal and migrations. To evaluate genetic ...

Background: Self-medication is the use of medication without prescription, orientation, or supervision of a physician or dentist. Self-medication might become a serious health problem. The purpose of this study was to ...

This study identified daily variations in oxygen consumption, antioxidant-defense system, and lipoperoxidation in the gills and hepatopancreas of the crab Chasmagnathus granulata (Dana, 1851) (Decapoda,Brachyura). In gills, ...

Melatonin is a biogenic amine, known from almost all phyla of living organisms. In vertebrates melatonin is produced rhythmically in the pinealocytes of the pineal gland, relaying information of the environmental light/dark ...

The aim of this study was to evaluate the role of cyclooxygenase (COX) in venous vascular reactivity changes after an oral lipid overload (OLO). Venous endothelial function (dorsal hand vein technique) was evaluated in ...

An exploratory methodology has been used to identify genes related to growth of the shrimp Farfantepenaeus paulensis (Pe¤rez-Farfante, 1967). Six hundred postlarvae, with an average ( SD) initial weight of 0.022 g ( 0.008), ...

Este artigo tem como objetivo apresentar o perfil de saúde dos trabalhadores marítimos de uma empresa de rebocadores do Rio Grande/RS. Trata-se de um estudo transversal cuja amostra constituída de 45 trabalhadores foi ...

Complementary feeding is defined as the process starting when breast milk alone is no longer sufficient to meet infant nutritional requirements and therefore other liquids and feed are needed along with it. The aim of this ...

With the aim of estimating the growth parameters, mortality, and reproduction of a population of Excirolana braziliensis, monthly samplings were performed in the period from June 1993 to May 1995 at Prainha Beach, Rio de ...

Homozygote individuals (HO) of the GH-transgenic zebrafish lineage (F0104), despite expressing double the amount of growth hormone (GH) in relation to the hemizygote (HE) individuals, presented smaller growth in relation ...

Purpose. To compare the acute effects of functional electrical stimulation (FES) with 15 and 50 Hertz (Hz) frequencies on muscle strength in patients with heart failure with healthy individuals.Methods. Twenty-two 61.6+1.0 ...

Lipids seem to be the major energy store in crustaceans. Moreover, they are extremely important in maintaining structural and physiological integrity of cellular and sub cellular membranes. During salinity adaptation, ...

Este estudo buscou clonar o cDNA do sbGnRH, identificar sua expressão em diferentes tecidos do linguado, bem como avaliar possíveis diferenças no RNA mensageiro (RNAm) desse gene no cérebro de linguados machos juvenis e ...

Neuropeptide Y (NPY) is considered the major stimulant for food intake in mammals and fish. Previous results indicate that NPY is involved in the feeding behaviour of the Brazilian flounder, Paralichthys orbignyanus. In ...

Estudo caso-controle, que objetivou analisar os fatores de risco associados ao baixo peso ao nascer de recém-nascidos de mães de Rio Grande-RS residentes nas proximidades da área industrial. Foram entrevistadas mães que ...

The circadian rhythm of black pigment migration of melanophores of the crab Chasmagnathus granulata and the variation in responsiveness of these cells to pigment-dispersing hormone (h-PDH), crustacean cardioactive peptide ...

The first and main target-structure of ultraviolet (UV) radiation in animals is the body surface, including the skin and eyes. Here, we investigated cell damage in the visual system of the crab Neohelice granulata acclimated ...

Even though growth hormone (GH) transgenesis has demonstrated potential for improved growth of commercially important species, the hormone excess may result in undesired collateral effects. In this context, the aim of this ...

Memory persistence needs a new event of consolidation 12 h after the acquisition. We investigated the role of the cholinergic activity on the persistence of memory. For this purpose, we performed the treatments 9 or 12 h ...

The presence of higher level of exogenous growth hormone (GH) in transgenic animals could lead to several physiological alterations. A GH transgenic zebrafish (Danio rerio) line was compared to nontransgenic (NT) samples ...
