Socio-economic and political motivations of Russian out-migration from Central Asia
Aijaz A.Bandey,Farooq AhmadRather 한양대학교 아태지역연구센터 2013 Journal of Eurasian Studies Vol.4 No.2
The unexpected fall of Soviet Union left ethnic Russians, outside Russia with many questions and concerns. Many of them emigrated to Russia from the erstwhile Soviet Union, for better conditions there. The disintegration of Soviet Union – a state created on the ideology of Communism was one of the reasons, apart from economic, political, socio-cultural, reasons besides the failure of Communism to keep the Soviet Union together were the main causes of Russian out-migration from Central Asia. The out-migration of Russians from Central Asia to Russia began in the 1970s as internal labour migration shifted in the wake of better job opportunities. It accelerated tremendously after 1991, and touched its highest mark in 1994, as a response to the relative economic prosperity of Russia at that time. Thus the improved standard of living in Russia and the desire to return to their cultural homeland were some major issues that concerned people to shift to Russia.
Rho-dependent Transcription Termination: More Questions than Answers
Banerjee Sharmistha,Chalissery Jisha,Bandey Irfan,Sen Ranjan The Microbiological Society of Korea 2006 The journal of microbiology Vol.44 No.1
Escherichia coli protein Rho is required for the factor-dependent transcription termination by an RNA polymerase and is essential for the viability of the cell. It is a homohexameric protein that recognizes and binds preferably to C-rich sites in the transcribed RNA. Once bound to RNA, it utilizes RNA-dependent ATPase activity and subsequently ATPase-dependent helicase activity to unwind RNA-DNA hybrids and release RNA from a transcribing elongation complex. Studies over the past few decades have highlighted Rho as a molecule and have revealed much of its mechanistic properties. The recently solved crystal structure could explain many of its physiological functions in terms of its structure. Despite all these efforts, many of the fundamental questions pertaining to Rho recognition sites, differential ATPase activity in response to different RNAs, translocation of Rho along the nascent transcript, interactions with elongation complex and finally unwinding and release of RNA remain obscure. In the present review we have attempted to summarize 'the knowns' and 'the unknowns' of the Rho protein revealed by the recent developments in this field. An attempt has also been made to understand the physiology of Rho in the light of its phylogeny.
