The Scorpions Lose Their Sting
23 While it would appear that the decision to incorporate or subsume the Directorate of Special Operations (or Scorpions), into the South African Police Service (SAPS) is a fait accompli, the process of incorporation will not be straightforward. This is largely because the decision to disband the Scorpions is politically motivated, rather than motivated by practical concerns around the function...
متن کاملAntiquity of microRNAs and their targets in land plants.
MicroRNAs (miRNAs) affect the morphology of flowering plants by the posttranscriptional regulation of genes involved in critical developmental events. Understanding the spatial and temporal dynamics of miRNA activity during development is therefore central for understanding miRNA functions. We describe a microarray suitable for detection of plant miRNAs. Profiling of Arabidopsis thaliana miRNAs...

Analyzing the city-state of Ḥaṭrā (Iraq, close to Kirkuk), it is demonstrated that pre-Islamic state craft in the region was dependent on the initiative of the Parthian monarchy in Iran. The kings of the Arsacid dynasty attempted to bestow the local Arabic tribes in the Jazira with a c...
متن کاملScorpions of Europe
This brief review summarizes the studies in systematics and zoogeography of European scorpions. The current “splitting” trend in scorpion taxonomy is only a reasonable response to the former “lumping.” Our better understanding of scorpion systematics became possible due to the availability of new morphological characters and molecular techniques, as well as of new material. Many taxa and local ...

The composition of their venoms is relatively simple as most toxins have a common structural motif that is found in other venoms from primitive species. Moreover, all the scorpion venom toxins principally act on membrane ionic channels of excitable cell...
