A sustained intraocular administration of neurotrophic factors is among the strategies aimed at establishing treatments for currently untreatable degenerative retinal disorders. In the present study we have analyzed the neuroprotective effects of a continuous neural stem (NS) cell-based intraocular delivery of ciliary neurotrophic factor (CNTF) on photoreceptor cells in the nclf mouse, an anima...
The bacterial H-NS protein silences expression from sequences with higher AT-content than the host genome and is believed to buffer the fitness consequences associated with foreign gene acquisition. Loss of H-NS results in severe growth defects in Salmonella, but the underlying reasons were unclear. An experimental evolution approach was employed to determine which secondary mutations could com...
the type of the applications for which internet is being used has changed over the years. multimedia applications, real-time applications and game playing require quality of service. ieee has proposed ieee 802.11e, a quality of service extension to the wireless lan standard ieee 802.11. in this paper service differentiation ability of 802.11e is evaluated. identical traffic is considered for al...
The gene expression state of exponentially growing Escherichia coli cells is manifested by high expression of essential and growth-associated genes and low levels of stress-related and horizontally acquired genes. An important player in maintaining this homeostasis is the H-NS-StpA gene silencing system. A Δhns-stpA deletion mutant results in high expression of otherwise-silent horizontally acq...
The data described in this article pertain to the genome-wide transcription profiling of a Vibrio cholerae mutant lacking the histone-like nucleoid structuring protein (H-NS) and the mapping of the H-NS chromosome binding sites [1, 2]. H-NS is a nucleoid-associated protein with two interrelated functions: organization of the bacterial nucleoid and transcriptional silencing [3]. Both functions r...
The avian coronavirus Infectious bronchitis virus (IBV), like other coronaviruses, expresses several small nonstructural (ns) proteins in addition to those from gene 1 (replicase) and the structural proteins. These coronavirus ns genes differ both in number and in amino acid similarity between the coronavirus groups but show some concordance within a group or subgroup. The functions and require...
