Blood islands are conglomerations of prevascular stem cells that form during vasculogenesis, a function critical to early vascular and hematopoietic development. In this paper, a model of blood island formation is proposed employing the approach of classical enzyme kinetics. Deterministic simulations of the model show the formation of blood island-like structures. These are compared to murine b...

background: scorpions are known as the most widespread poisonous creatures that cause casualties and death to human. they are distributed in tropical and subtropical areas. among the sixteen iranian island in the persian gulf, qeshm island is the biggest and is located in the focus of the important internal and international commercial marinelines. furthermore, thousands of tourists also visit ...

conclusions scarring of the neck produces problems with function, and appearance. in our view, the supraclavicular flap, a thin flap of good texture, is an excellent and highly reliable flap for covering defects of the anterior neck. this flap is easy to harvest, with good functional and aesthetic results. results thirty-seven of the 41 flaps survived completely, but there were three cases of d...

CpG islands mark CpG-enriched regions in otherwise CpG-depleted vertebrate genomes. While the regulatory importance of CpG islands is widely accepted, it is little appreciated that CpG islands vary greatly in lengths. For example, CpG islands in the human genome vary ∼30-fold in their lengths. Here we report findings suggesting that the lengths of CpG islands have functional consequences. Speci...

In this study, a male specimen of John dory (Zeus faber) with 31.4 cm in total length and 365.43 g body weight was caught trammel net at depth 15 m from Fener Island the province Fatsa (Ordu, Black Sea). This record is first verified report suggesting that expanded its distribution Mediterranean towards Geographical Sub-Area 29 (Black

When multiple groups of organisms experience similar environmental gradients, their patterns of differentiation might exhibit both shared and unique features. Here, we investigated the relative importance of three factors in generating body shape variation in a livebearing fish, Gambusia caymanensis, inhabiting the Cayman Islands: (i) shared patterns of divergent selection between predator regi...

BACKGROUND The goal of this study was to investigate the anatomy of the peroneal artery and its perforators, and to report the clinical results of reconstruction with peroneal artery perforator flaps. METHODS The authors dissected 4 cadaver legs and investigated the distribution, course, origin, number, type, and length of the perforators. Peroneal artery perforator flap surgery was performed...

In this paper, we applied landscape scale wildfire simulation modeling to explore the spatiotemporal patterns of wildfire likelihood and intensity in the island of Sardinia (Italy). We also performed wildfire exposure analysis for selected highly valued resources on the island to identify areas characterized by high risk. We observed substantial variation in burn probability, fire size, and fla...

Island biogeography theory can be used to explain patterns of species richness on various types of habitat islands, including freshwater lake systems. Mollusk production in these systems also has been linked to various water-chemistry variables, such as pH, alkalinity, hardness, and specific conductance. We examined how mollusk diversity patterns were related to geographical and limnological fa...
