Low molecular weight Polycyclic Aromatic Hydrocarbons (PAHs) are widely concerned due to their significant health risks such as carcinogenicity, reproductive- and endocrine-disrupting effects, immunotoxicity and neurotoxicity on human and marine animals. The induction pattern of xenobiotic metabolizing cytochrome P4501A (CYP1A1) gene was studied on...

Mangrove forests as one of the most important coastal ecosystems provide important ecological and economic performance to the world, have been threatened by developmental human activities and subsequent land use changes. The present study aims to assess mangrove ecosystem health in Nayband Marine National Park, Iran using Mangrove Quality Index (MQ...

Biocompatible syntheses of Cu2O nanoparticles are relatively low compared to some other reported metal oxides due to their low stability and requiring more carefully controlled synthetic conditions. In the present study, the efficiency of three brown algae (Cystoseira myrica,Sargassum latifoliumandPadina australis) extracts collected from the Persi...

In this study, sodium alginate was extracted from the Sargassum algae, collected from coastal waters of Bushehr, Persian Gulf, Iran and used as a stabilizing and wrapping agent for CuO...

Traditionally fish from family Sillaginidae considered as Sillago sihama in the North Persian Gulf. Genetic as well as morphological analyses were used to study species differentiation of Sillaginids in the North Persian Gulf. Meristic counts and geometric morphometrics were used to morphologically differentiate specimens. We sequenced a 620 bp fra...

Silaginidae family fish from Perciforms, are appropriate candidates for shallow water and coastal aquaculture. At least three species of this family represents in the Persian Gulf. Genetic analysis of Sand whiting Sillago sihama , the most common species of family performed using COI gene. During the present study 10 samples were collected from Bus...

In the present report, we focused on the screening of antibacterial, hemolytic and cytotoxic activities of Holothuria parva sea cucumber from the Persian Gulf for potential application in nutraceutical and pharmaceutical products. Ethanol, methanol and aqueous extracts of H. parva were prepared by maceration of milled body wall pieces. Cytotoxicity...

Yellowfin seabream is reproduced both naturally and semi-artificially and is one of the most probable candidates for coastal aquaculture in Iran. Genetic structuring of wild Acanthopagrus latus populations from the Northern Persian Gulf and Gulf of Oman was analyzed using microsatellite markers. Allelic diversity was estimated in 180 organisms (3 s...

Introduction Thalassemia is the most prevalent monogenic disorder worldwide resulting from the inappropriate production of heme. patients need repeated transfusion and this lead to elevated ferritin level and also iron overload. hepcidin, encoded by hamp gene, is a recently discovered 25 amino acid appears to play a crucial role in iron homoeostasi...

Today by spreading of existing diseases and emergence of new infections, special attention to the vaccinology is necessary. In the past decade the progress made in the process of gene sequencing, pathogens gene sequencing more rapidly done. That accelerates the process of the new vaccine manufacturing. The protection against invading pathogens and...

The effect of carrot (Daucus carota) (in form of steamed carrot) mixed in basal wet diet at 10, 15, 20, 25 and 30% and a control group without any carotenoid supplementation, on skin pigmentation of zebra Malawi cichlid (Pseudotropheus zebra) was evaluated. Totally 180 zebra Malawi cichlid (15 g mean weight) were stocked in 18 aquariums (70 L) each...

There is a growing concern over aquatic pollution because of its detrimental effects on biological life including human beings. The goal of the present study was to determine the acute toxicity of diazinon and deltamethrin as potential dangerous organic pesticides to assess mortality effects of these chemicals to the blue gourami, Trichogaster tric...

Polycyclic Aromatic Hydrocarbons (PAHs) which their carcinogenic and mutative effects have been proved are one of the major categories of pollutants entering the marine environment. Due to their hydrophobic, lipophilic characteristics, they accumulate in the sediments of coastal areas. Khowre-Musa System as a semi enclosed ecosystem receives high l...

Habitat classification provides an important tool for nature conservation. The Coastal Marine Ecological Classification Standard (CMECS) was developed to meet this need and provide a universally accepted standard classification for coastal and marine habitats. The biological Cover (Biotic Cover Component, BCC) is the biotic aspects of substrate at...
