Four important hungarian common carp (Cyprinus carpio l.) breeds (attala mirror, attala scaled, hortobágy scaled and Szeged mirror) harvested from different fish farms were analysed in this study. Main body indices, slaughter characteristics, fillet fat content, and conventional fish flesh quality characteristics were measured and compared. the slaughter value of the mirror strains tended to ex...

Introduction Developments in the management of fish reproduction have had major impacts on the growth of aquaculture. The capability to spawn fishes under controlled conditions ensures an adequate supply of young for growout, whether for food or stocking (Zohar, 1989; Yaron and Zohar, 1993). Artificial propagation techniques have facilitated worldwide introduction of important species by removi...

Acute toxicity of commercial grade organophosphate insecticide, quinalphos (25% emulsified concentration) to common carp (Cyprinus carpio) was tested through bioassay. The acute toxicity of quinalphos to the fingerlings exposed for 96 hr was found to be 2.75 ppm. For sub lethal toxicity study, the fish were exposed to two concentration viz., 1/10th of LC50 (0.275 ppm) and 1/5th of LC50 (0.55 pp...

Nitric oxide (NO) has been implicated in the pathogenesis of migraine and treatment with its exogenous donor glyceryl trinitrate (GTN) represents widely accepted experimental "migraine model". In this study, glyceryl trinitrate was administered intraperitoneally to carps, serum nitrite and nitrate levels were determined, permeability of blood-brain barrier was investigated, and histological cha...

INTRODUCTION The aim of this study was to investigate the variation in the amount of the orthodontically induced tooth movement in humans and potential associations between the amount of tooth movement with age and location in the mandible or maxilla. SUBJECTS AND METHODS This study included 11 participants (7 females, 4 males) with an age range of 11.3-28.6 years. In a standardized experimen...

OBJECTIVE This study was intended to optimize perlite particle size and morphology for better tooth cleaning and lower tooth abrasion, and to evaluate the performance of a whitening toothpaste containing the optimized perlite abrasive for tooth cleaning, abrasion, and polishing. METHODS Perlite toothpaste abrasive samples were prepared by air classifying a commercial expanded perlite product....

The cDNAs encoding glutathione peroxidase (GPx) were cloned and sequenced from the liver of three Chinese carps with different tolerance to hepatotoxic microcystins, phytoplanktivorous silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis), and herbivorous grass carp (Ctenopharyngodon idellus). Using genome walker method, a 750 bp 5'-flanking region of the silver carp...

Effective management of rare species, including endangered native species and recently introduced nonindigenous species, requires the detection of populations at low density. For endangered species, detecting the localized distribution makes it possible to identify and protect critical habitat to enhance survival or reproductive success. Similarly, early detection of an incipient invasion by a ...

Reef-building corals begin as non-calcifying larvae that, upon settling, rapidly begin to accrete skeleton and a protein-rich skeletal organic matrix that attach them to the reef. Here, we characterized the temporal and spatial expression pattern of a suite of biomineralization genes during three stages of larval development in the reef-building coral Pocillopora damicornis: stage I, newly rele...
