investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Intrauterine growth retardation (IUGR) is associated with vascular complications leading to hypoxia and abnormal fetal development. The effect of IUGR on L-arginine transport and nitric oxide (NO) synthesis was investigated in cultures of human umbilical vein endothelial cells (HUVECs). IUGR was associated with membrane depolarization and reduced L-arginine transport (V(max)= 5.8+/-0.2 versus 3...
protein secretory systems are found in all living organisms including gram negative bacteria, and eukaryotic cell’s organelles that are derived from these bacteria. unlike all other living organisms, gram negative bacteria have different protein secretory systems. at least there are four different independent secretory systems, which are responsible to transport the secreted proteins to the mil...
An experiment was conducted to determine the effects of different levels of feed intake at 70%, 85% and 100% of the voluntary feed intake on digestibility and rumen microbial protein synthesis. For this purpose, six male lambs (42±1.5 kg BW) were used in a replicated Latin square design (replicated in three periods that were 21 days each). A twenty five days period was assigned as adaptati...

Background and Objective: Salubrinal- a protein synthesis inhibitor- plays a crucial role in sleep and neuronal inhibition through the GABA activation. According to these evidences, the aim of the present study was to determine the effect of salubrinal on epileptic seizures induced by pentylenetetrazol (PTZ). Materials and Methods: In this expremental study under stereotaxical surgery,...
The regulation of the transport of leucine, isoleucine, and valine in Escherichia coli B/r was studied in a mutant with a complete deletion of the leucine biosynthetic operon and a temperature-sensitive leucyl-tRNA synthetase [L-leucine:tRNALeu ligase (AMP-forming), EC 6.1.1.4]. Under conditions of excess leucine and a functional leucyl-tRNA synthetase transport activity was repressed. Shifting...
Top-down proteomics has enabled the elucidation of heterogeneous protein complexes with different cofactors, post-translational modifications, and membership. This heterogeneity is believed to play a previously unknown role in cellular processes. The molecular forms complex have come be called “complex isoform” or “complexoform”. Despite complexoform, it remains unclear how whether circuits con...
The synthesis of the periplasmic galactose-binding protein of E. coli is regulated by events occurring during its cell cycle, and proceeds in synchronized cells for only a short period after cell division is completed. Transport activity mediated by the fl-methylgalactoside transport system follows closely the synthesis pattern of the binding protein. A mutant, E. coli BUG-6, exhibits temperatu...
