Eurasian rivers with immense watersheds, particularly the Severnaya Dvina, Pechora, Ob, Yenisei, Lena, and Kolyma Rivers, provide a massive flux of warm waters into the Arctic Ocean or peripheral seas contributing to melt sea ice in spring and summer.
Together with similarly treasured resources such as shark fins and bird nests, trepang belongs to a group of commodities which were so valuable that "distant seaside cliffs and seemingly peripheral seas became sought-after destinations" [3:138].
To report the rare occurrence of peripheral retinal sea-fan neovascularization in a patient with chronic rhegmatogenous retinal detachment and describe the surgical management.
Our case illustrates the rare but possible association of chronic retinal detachment with peripheral retinal sea-fan neovascularization; although the incidence is rare it may pose diagnostic and treatment dilemmas.
In what are here denoted "peripheral" Arctic regions (Sea of Okhotsk, Bering Sea, Gulf of St. Lawrence), the winter ice extents do not provide complete ice cover of the sea region, while in at least one peak summer month (July, August, September) there is no ice cover at all.
Fundoscopy of the RE revealed a chronic inferotemporal retinal detachment and peripheral neovascularization with a sea fan configuration.
The sedimentary rocks provide sensitive records of differential basement subsidence, the geomorphic evolution of the peripheral orogenic belts, fluctuations of sea level, and climatic changes related in part to latitudinal continental drift.
Mr. Nasheed also faces difficulties back home, though these, apart from the rising seas, are fairly peripheral to "The Island President".
Interestingly, although yolk platelets are distributed at random in the sea urchin egg, NAADP induces a peripheral vesicular alkalinization, even when injected into the middle of the egg, suggesting the presence of a subpopulation of NAADP-sensitive stores [ 6].
In addition, high-altitude residents frequently report malaise and dizziness when they descend to low altitudes and anecdotal reports describe the need for bigger boots due to peripheral oedema when soccer players from altitude perform at sea level.
