چکیده

in less than 150 words) The “Scattered islands” (literal translation of “les Iles Éparses”) stretch down the length of the Mozambique Channel, between the east coast of Africa and Madagascar. These islands are fairly remote and largely still intact, offering sites of high conservation value. Introduction The Iles Éparses are an administrative unit rather than a single geological unit, with the northern banks (Glorieuses and Geyser) likely being extensions of the Comoros archipelago, while the middle and southern islands are distinct geological features. Oceanographically, the islands are bathed by the variable eddies of the Mozambique channel with resulting enhanced productivity driven by the eddies and their interactions with the continental slopes and island slopes, but there is strong differentiation from north to south. In the north, the “Glorioso Front” was christened for its proximity to Glorieuses island, and may mark the transition from the SEC to the waters of the channel. Juan de Nova is at a point off the Madagascar west coast characterized by significant aggregations of marine mammals, an indicator of high productivity likely driven by interactions between eddies and the shallowest sections of the Davie ridge. Europa and Bassas de India, in the center of the southern Mozambique channel, experience mature eddy systems. While the individual islands are all small, as a group they cover a large geographic range across the whole of the Mozambique channel. The integrity of the serial/island group is very high as the islands are uninhabited and human pressure very low. All studies show that marine habitats are in good health despite recent climate change impacts, and the composition of the trophic chain, with abundance of top predators is a sign of good health. Nevertheless, each island has a distinctive character, and provided the productivity and dynamics of open sea areas that are critical for feeding and migration remain in good condition, each island has a high integrity.

Backgound and Aim: One important limitation of random pattern skin flap in plastic surgery is the necrosis of distant parts of the flap resulting from ischemia. This effect cause unwanted increase in the costs and hospitalization. Previously, large number of factors has been evaluated to decrease the flap necrosis. In present study we used two drugs. Main reason was their mechanism of action th...

Nitric oxide within the rat hippocampal CA1 area may play a role in morphine tolerance

Hippocampus as part of the limbic system plays an important role in abused drugs-induced memory. The role of glutamate receptor within the hippocampal CA1 area in morphine-induced memory has also been postulated. Previous studies indicated that glutamate receptors exert their effects in part through the release of nitric oxide (NO). In the present study, the effects of intra-CA1 area injections...
