The freshwater angel fish (Pterophyllum scalare Schultze, 1823) is South American cichlid become very popular among aquarists. There is little information on their culture and aquarium husbandry. In this study growth performance and survival rate of angelfish subjected to different feeding frequencies were evaluated. Four groups of angel fish juveniles (0.87 ± 0.01 g; 3.98 ± 0.08 mm) were fed e...

 Post larvae of wild and cultured spawners of the Indian white shrimp (Penaeus indicus, Milne Edwards, 1837) were reared to market size, in commercial ponds of shrimp farming site of Helleh, in Bushehr Province, during a six months period. Environmental factors, management process and the diet used to feed shrimps were almost similar for both treatments. Averages of the weight, length, specific...

Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six ...

Evidence has been mounting (over the centuries) that the interest based debt financing regime is under ever increasing distress. All of the earlier crises whatever label they carried− exchange rate crisis or banking crisis – have been debt crises in essence. At the present, empirical research suggests that the debt-to-GDP ratio of the richest members of the G-20 threatens to touch 120% m...

Introduction: Cardiovascular disease is considered as the most important cause of mortality among men and women throughout the world. This condition causes sudden cardiac arrest in more than half of the cases. To reduce mortality due to this disease, cardiopulmonary resuscitation (CPR) and the determinants of its success are the focus of researchers. Objective: The aim of this study was to det...

objective: low quality of the bone and insufficient bone due to the size of the sinus and resorption of the alveolar ridge decrease the long-term survival of implants in the posterior maxilla compared to other regions of the jaws. surgical procedures to increase bone volume make it possible to place implants longer than 8 mm. in this situation sinus elevation makes it possible to place implants...

objective(s): covering tissue defects using skin flaps is a basic surgical strategy for plastic and reconstructive surgery. the aim of this study was to evaluate the effects of chicken embryo extract (cee) and bone marrow derived mesenchymal stem cells (bm-mscs) on random skin flap survival (rsf) in rats. using chicken embryo extract can be an ideal environment for the growth and proliferation ...
