Membrane fusion in eukaryotic cells is thought to be mediated by a highly conserved family of proteins called SNAREs (soluble N-ethyl maleimide sensitive-factor attachment protein receptors). The vesicle-associated v-SNARE engages with its partner t-SNAREs on the target membrane to form a coiled coil that bridges two membranes and facilitates fusion. As demonstrated by recent findings on the he...

Cameron, H. U. and Fornasier, V. L. (1974). Thorax, 29, 472-474. The manubriosternal joint-an anatomicoradiological survey. The movement of the manubriosternal joint is said to be a significant factor in respiration. The incidence of fusion of the manubriosternal joint in necropsy cases has been investigated with fine detail radiography. In over 600 cases, fusion of the joint was found in 14% a...

Mitochondrial homeostasis reflects a dynamic balance between membrane fission and fusion events thought essential for mitochondrial function. We report here that altered expression of the C. elegans BCL2 homolog CED-9 affects both mitochondrial fission and fusion. Although striated muscle cells lacking CED-9 have no alteration in mitochondrial size or ultrastructure, these cells appear more sen...

Prior efforts have shown that under certain situations, retrieval effectiveness may be improved via the use of data fusion techniques. Although these improvements have been observed from the fusion of result sets from several distinct information retrieval systems, it has often been thought that fusing different document retrieval strategies in a single information retrieval system will lead to...

The final stages of dengue virus fusion are thought to occur when the membrane-proximal stem drives the transmembrane anchor of the viral envelope protein (E) toward the fusion loop, buried in the target cell membrane. Crystal structures of E have lacked this essential stem region. We expressed and crystallized soluble mutant forms of the dengue virus envelope protein (sE) that include portions...

Recently proposed techniques like mini-graphs, CCA-subgraphs, and static strands exploit application-specific compound or fused instructions to reduce execution time, energy consumption, and/or processor complexity. To achieve their full potential, these techniques rely on static tools to identify common instruction sequences that make good fusion candidates. As a result, they also rely on ISA ...

in this study, mutant forms of bacillus thuringiensis spp. israelensis (h14) were produced. these mutants were identified when the cells were cultured on chloramphenicol plates and stained with crystal violet. protoplasts of the mutants were isolated by enzymatic digestion (lysozyme) of the cell walls at the presence of an osmotic stabilizer. the protoplasts were induced to fuse to each other i...

fusion is an anomaly manifested in both deciduous and permanent dentitions. fu- sion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. triple tooth refers to the :union: of three separate tooth entities. it can occur by fusion, germination,...

original article   mental fatigue (mf) is considered as a contributor factor in incident, even catastrophic one. electroencephalography measurement has been the most acceptable method to assess mf by neurologists. however, this method could be hardly feasible in real work setting. flicker fusion device, by contrast, is more usable at work setting. the purpose of this study was to compare the cr...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...
