This work addresses the issue of dynamic spectrum allocation among multiple wireless access networks (ANs) having different (not necessarily competing) technologies. The heterogeneous network architecture considered in this work consists of several such ANs owned by a single service provider (SP). A network entity, called local spectrum controller (LSC), controls the spectrum pool and distribut...

BACKGROUND Leukemia stem cells (LSC) are involved in the incidence, drug resistance, and relapse of leukemia while LSC-related antigen CD33, CD96, and DAPK expression in AML and its prognosis is still unclear. This study explored LSC-related antigens expression in acute myeloid leukemia (AML) and its prognosis. MATERIAL AND METHODS A total of 156 cases of AML patients were enrolled in the exper...

ITD-Flt3 mutations are detected in leukemia stem cells (LSCs) in acute myeloid leukemia (AML) patients. While antagonizing Survivin normalizes ITD-Flt3-induced acute leukemia, it also impairs hematopoietic stem cell (HSC) function, indicating that identification of differences in signaling pathways downstream of Survivin between LSC and HSC are crucial to develop selective Survivin-based therap...

Study Design Case report. Objective Lumbar juxtafacet cysts (synovial and ganglion cysts) are a rare cause of low back and radicular leg pain. Most patients with lumbar cysts are in their sixth decade of life and have significant facet joint and disk degeneration. Lumbar synovial cysts (LSCs) are extremely rare in adolescence and young adulthood, and to our knowledge, only two pediatric cases o...

PURPOSE Traumatic events and adverse stressful experiences are major etiological factors in a wide variety of physical and mental disorders. Developing psychological instruments that can be easily administered and that have good psychometric properties have become an integral part for research and practice. This study investigated the reliability and validity of the Korean version of the Lifeti...

For the Rayleigh-number range 10 Ra 10 we report measurements of the Nusselt number Nu and of properties of the large-scale circulation (LSC) for cylindrical samples of helium gas (Prandtl number Pr=0.674) that have aspect ratio Γ ≡D/L=0.50 (D and L are the diameter and the height respectively) and are heated from below. The results for Nu are consistent with recent direct numerical simulations...

BACKGROUND Caspase activation is a critical early step in the onset of apoptosis. Cell-permeable fluorogenic caspase substrates have proven valuable in detecting caspase activation by flow cytometry. Nevertheless, detection of early low-level caspase activation has been difficult using conventional area or peak fluorescence analysis by flow cytometry, despite the apparent presence of these cell...

In this scientific research, for the first time, the removal of radioactive strontium-90 (90Sr) by γ-MnO2-AgA zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as pH, temperature, adsorbent amount and the contact time that are examined from drinking water of Ramsar city and monitored via Ultra Low-Level Liquid Scintillation Counting (LSC) technique. Pri...

The balance between stomatal and mesophyll conductance has been reported to directly influence intrinsic water-use efficiency (WUEi), but it is unclear whether variations in limitations (lsc lm, respectively) affect WUEi during soil drought rewatering. Limitations (lsc, lm biochemical limitation, lb) were measured Manchurian ash (Fraxinus mandshurica Rupr.) Mongolian oak (Quercus mongolica Fish...

Protein evolution includes the birth and death of structural motifs. For example, a zinc finger or a salt bridge may be present in some, but not all, members of a protein family. We propose that such transitions are manifest in sequence phylogenies as concerted shifts in substitution rates of amino acids that are neighbors in a representative structure. First, we identified rate shifts in a qua...
