Bone marrow-derived stem cells have the ability to migrate to sites of tissue damage and participate in tissue regeneration. The number of circulating stem cells has been shown to be a key parameter in this process. Therefore, stimulating the mobilization of bone marrow stem cells may accelerate tissue regeneration in various animal models of injury. In this study we investigated the effect of ...

Cyanophyta of some paddy-fields of Golestan province (North of Iran, near the Caspian Sea) have been studied during 2006–07. Phormidium subinerusatum, P. tenue, P. jadinianum, P. purpurascens, P. lucidum, P. fragile, Microcoleus palaodus, M. lacustris are new records for Golestan province and Iran. Results showed that  P. subinerusatum, P. tenue were dominant in all stations. P. fragile, in spr...

 Phytoplankton groups have specific role in the water quality of Neor Lake for living of fishes in Ardabil province. So, in order to study water quality and fish stocks assessment of Neor Lake after entering Carassius gibelio, primary products of this lake at first should be evaluated.This investigation carried out in 5 stations and 8 months during 2014. Phytoplankton sampled by 1 liter Ruttner...

Cyanophyta or cyanobacteria are a phylum of bacteria which obtain their energy by performing photosynthesis. Cyanobacteria are the oldest photosynthetic organisms that evolved on Earth approximately 2.6 to 3.5 billion years ago (Hedges, et al., 2001). They are generally called as bluegreen algae, which is a misnomer, as cyanobacteria are prokaryotic and algae are eukaryotic (Allaby, 1992). Cyan...

In recent decades, increasing frequency and intensity of saltwater intrusion in the Modaomen Channel has threatened the freshwater supply in the surrounding cities of the Pearl River Estuary, and ulteriorly changed the environmental conditions of the estuarine waters. Phytoplankton biomass, primary production (PP) and species composition, as well as hydrological and chemical parameters were exa...

Mundaú and Manguaba Lagoons (9 degrees 34' 38'-9 degrees 45' 30' S and 35 degrees 44' 00'-35 degrees 58' 13' W) are considered the largest and most productive ones in the state of Alagoas and were studied with the purpose of identifying the existence of anthropic impacts. Samples were collected at 8 stations, during low tide and flooding in rainy and dry periods, using the 'Van Dorn' bottle and...

A biological study was conducted to find out about reproduction and feeding of G. lacustris in Neur Lake from northwest mountains of Iran. Plankton diversity, hydro-chemical factors and substrate characteristic were recorded monthly. Findings showed that reproduction period of this species was short and limited to May and the mean brood size was 10.2 ± 5.3 eggs per female. The hydro-chemical an...
