Constructing dataset of classified drainage areas based on surface water-supply patterns in High Mountain Asia

The High Mountain Asia (HMA) region, ranging from the Hindu Kush and Tien Shan in the west to the Himalaya in the south with an altitude between 2000 and 8844 m, holds the largest reservoir of glaciers and snow outside Earth Polar Regions. In the last decades, numerous glaciers and lake areas there have undergone tremendous changes with water redistribution. In order to increase understanding of the pattern of distribution of water resources, and their dynamic changes at the basin scale, a watershed classification based on the water replenishment patterns dataset was constructed. The input dataset are from the Randolph Glacier Inventory V.6.0 and the vector data of rivers and streams. Four datasets were thus obtained: Glacier-fed and Runoff-fed Drainage Area (GRDA), Glacier-fed and Runoff-free Drainage Area (GDA), Glacier-free and Runoff-fed Drainage Area (RDA), and the Glacier-free and Runoff-free Drainage Area (NGRDA), and the numbers of these four types of basins are 87, 107, 32, and 448 separately. The statistical results show GRDA has the largest surface area, accounting for 82.2% of the total basin area in HMA, mainly in the region of the basin with outflow rivers or streams. Dominated by small basins, the GDA area accounts for the smallest area, only 3.86% and the RDA accounts for 5.62%. For NGRDA, most are with small areas, accounting for 8.32%, and mainly distributes in the closed basin of the Qiangtang Plateau. This dataset provides a fundamental classified data source for research on water resources, climate, ecology, and environment in HMA.

Down-regulation of heme oxygenase-1 by SVCV infection

Heme oxygenase (HO-1) is a cytoprotective enzyme that plays a critical role in defending the body against oxidant-induced injury during inflammatory processes. In mammalian systems, viral infection or antigen expression can down-regulate the expression of HO-1. In turn, the induction of HO-1 or overexpression of HO-1 results in potent and direct antiviral activity that targets the replication of several mammalian viruses. In this study, the HO-1 gene of Cyprinus carpi was cloned, and the expression profile of HO-1 was investigated during spring viremia of carp virus (SVCV) infection. The results demonstrate that the expression of HO-1 was down-regulated during SVCV infection in the EPC cells and in common carp. These results indicated that SVCV infection could induce host oxidative stress, which may contribute to tissue injury in affect fish. Crown Copyright (C) 2011 Published by Elsevier Ltd.
