Salamanders and lungfishes are the only sarcopterygians (lobe-finned vertebrates) capable of paired appendage regeneration, regardless amputation level. Among actinopterygians (ray-finned fishes), regeneration after at fin endoskeleton has been demonstrated in polypterid fishes (Cladistia). Whether this ability evolved independently or a common origin remains unknown. Here we combine assays comparative RNA-sequencing (RNA-seq) analysis Polypterus axolotl blastemas to provide support for...
Salamanders are the only living tetrapods capable of fully regenerating limbs. The discovery salamander lineage-specific genes (LSGs) expressed during limb regeneration suggests that this capacity is a novelty. Conversely, recent paleontological evidence supports deeper evolutionary origin, before occurrence salamanders in fossil record. Here we show lungfishes, sister group tetrapods, regenerate their fins through morphological steps equivalent to those seen salamanders. Lungfish de novo...
This study evaluated the in vitro and vivo parasiticidal efficacy of essential oils Mentha piperita, Lippia alba Zingiber officinale on Neoechinorhynchus buttnerae (acanthocephalan) their effect when used as dietary supplementation hematological parameters Colossoma macropomum. For assay, parasites were exposed to five different concentrations (360, 540, 720, 1440, 2880 mg L−1) diluted 3% Tween 80, for incubation period 24 hs observed each 15 min. The oil M. piperita caused mortality 100 % 2...
The unique eyes of the four-eyed fish Anableps anableps have long intrigued biologists. Key features associated with bulging eye include expanded frontal bone and duplicated pupils cornea. Furthermore, retina expresses different photoreceptor genes in dorsal ventral regions, potentially distinct aerial aquatic stimuli. To gain insight into developmental basis eye, we examined neurocranium ontogeny, as well gene expression during larval stages. First, described six stages which duplication...
Infection by the acantocephalan Neoechinorhynchus buttnerae is considered one of most important concerns for tambaqui fish (Colossoma macropomum ) production. Treatment strategies have been focus several in vivo studies; however, few studies undertaken on vitro protocols parasite maintenance. The aim present study was to develop best culture condition N. ensure its survival and adaptation out host allow testing substances be used control parasite. To achieve this, parasites were collected...
ABSTRACT The pelvic fins of male South American lungfish, Lepidosiren paradoxa , are adorned with a distinctive array filaments, which grow and become highly vascularized during the breeding season. resemblance between these fin filaments (PFFs) external gills other vertebrates suggested that this gill‐like structure was used for physiological gas exchange. It has been proposed unique L . is release oxygen from its blood into environment in order to aerate nesting brood, or, conversely, as...
Plants have developed a sophisticated regulatory network that coordinates gene expression in meristematic zones response to environmental conditions. Here, we identified protein Arabidopsis (Arabidopsis thaliana) interacts with Armadillo BTB 1 (ABAP1), negative regulator of the cell cycle plants. We characterized ABAP1 Interacting Protein (named AIP10) investigating its role modulating plant development. T-DNA insertion lines silenced AIP10 were evaluated phenotypically (morphology, fresh...
O presente artigo propõe a verificação do índice de perda por encolhimento e peso hambúrguer peixe ou “fishburguer”, elaborado com matéria-prima da Tambatinga (híbrido Colossoma macropomum X Piaractus brachypomus) no Laboratório Tecnologia Alimentos – UEMA. Foi uma única formulação utilizando CMS- Carne Mecanicamente Separada filé adicionado ingredientes seco agentes liga. Todas as análises foram realizadas em triplicata. Os testes para avaliação seu tamanho executados dois momentos, antes...
O objetivo deste estudo foi avaliar as propriedades nutricionais da CSM (Carne Separada Manualmente) das espécies tibiro (Oligoplites palometa) e cururuca (Micropogonias furnieri) de acordo com três níveis lavagens, verificar a quantidade nutrientes perdidos durante este processo. Foram extraídas carnes 10 exemplares cada espécie. Os peixes foram adquiridos inteiros, levados ao laboratório Físico-química alimentos UEMA, onde lavados água, eviscerados submetido à extração carne forma manual....
O objetivo deste trabalho foi enriquecer biscoitos com prote�na de pescado, para estimular o consumo entre crian�as escolas p�blicas. Devido baixo determinado pela FAO, e base nos dados que pescado tem um alto valor comercial, perante uma popula��o baixa renda, utilizamos neste peixe como a cururuca (Micropogonias furnieri), esse adquirido na feira S�o Lu�s, levado ao laborat�rio da Universidade Estadual do Maranh�o retirada CMS (Carne mecanicamente separada retirado umidade estufa 105� C em...
Salamanders and lungfishes are the only sarcopterygians (lobe-finned vertebrates) capable of complete limb paired fin regeneration, respectively. Among actinopterygians (ray-finned fishes), regeneration after amputation at endoskeleton has been demonstrated in Polypterid fishes (Cladistia). Whether appendage evolved independently or a common origin remains unknown. Here we combine assays comparative RNA-seq analysis to provide support for osteichthyes (bony vertebrates). We show that,...
