Two almost identical proteins with 70 amino acid residues each, closely packed by four disufide bridges, and molecular masses of 7899.5 and 7884.7 were isolated and sequenced from the venom of the scorpion Isometrus vittatus from Pakistan. They differ by an acidic amino acid residue (glutamic or aspartic) at the same position 55 of the peptide chain, however, they exhibit the same length, the s...

In an attempt to determine the nature of possible interspecific differences in osmotic responses to dehydration, the following species of two scorpion families were examined: Scorpio maurus fuscus (Scorpionidae) and Buthotus judaicus (Buthidae) from the mesic Lower Galilee (mean annual precipitation approximately 525 mm); and Scorpio maurus palmatus (Scorpionidae) and Leiurus quinquestriatus (B...

In this study, the cDNA of a new peptide from the venom of the scorpion, Buthotus saulcyi, was cloned and sequenced. It codes for a 64 residues peptide (Bsaul1) which shares high sequence similarity with depressant insect toxins of scorpions. The differences between them mainly appear in the loop1 which connects the beta-strand1 to the alpha-helix and seems to be functionally important in long ...

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 t...

The Indonesian pastime of keeping wild birds as pets is threatening the long-term survival of many songbird species on the islands of Java and Bali. Here we present the results of a large-scale household survey of bird-keeping in the six largest cites of Java and Bali that investigates: (1) the scale and conservation significance of bird-keeping and (2) the relative merits of regulatory versus ...

Given a matroid M with distinguished element e, a port oracle with respect to e reports whether or not a given subset contains a circuit that contains e. The rst main result of this paper is an algorithm for computing an e-based ear decomposition (that is, an ear decomposition every circuit of which contains element e) of a matroid using only a polynomial number of elementary operations and por...
