The day-time eastward equatorial electric field (EEF) in the E-region plays an important role in equatorial ionospheric dynamics. It is responsible for driving the equatorial electrojet (EEJ) current system, equatorial vertical ion drifts, and the equatorial ionization anomaly (EIA). Due to its importance, there is much interest in accurately measuring the EEF. However, there is a severe lack o...

There is rich biodiversity and biomass in wetlands and these areas are important in ecosystems. Assessment of the environment of wetlands is critical in the management of pivotal ecosystems. The energy ecological footprint (EEF) is an improved form of the ecological footprint method based on the theory of energy value. EEF can be a useful tool for comparing and monitoring environmental impacts....

Memory consolidation, which converts acquired information into long-term storage, is new protein synthesis-dependent. As protein synthesis is a dynamic process that is under the control of multiple translational mechanisms, however, it is still elusive how these mechanisms are recruited in response to learning for memory consolidation. Here we found that eukaryotic elongation factor-2 (eEF-2) w...

Translation elongation factor 1alpha (EF-1alpha, or EF-Tu in bacteria) is a highly conserved core component of the translation machinery that is shared by all cellular life. It is part of a large superfamily of GTPases that are involved in translation initiation, elongation, and termination, as well as several other cellular functions. Eukaryotic EF-1alpha (eEF-1alpha) is well studied and widel...

Patients with tuberous sclerosis complex (TSC) develop hamartomatous tumors showing loss of function of the tumor suppressor TSC1 (hamartin) or TSC2 (tuberin) and increased angiogenesis, fibrosis, and abundant mononuclear phagocytes. To identify soluble factors with potential roles in TSC tumorigenesis, we screened TSC skin tumor-derived cells for altered gene and protein expression. Fibroblast...

The Saccharomyces cerevisiae Yor112wp, which we named Cex1p, was identified using a yeast tRNA three-hybrid interaction approach and an in vivo nuclear tRNA export assay as a cytoplasmic component of the nuclear tRNA export machinery. Cex1p binds tRNA saturably, and associates with the nuclear pore complex by interacting directly with Nup116p. Cex1p co-purifies with the nuclear tRNA export rece...

BACKGROUND Nasopharyngeal carcinoma (NPC) has a high relapse and metastatic rates; hence, development of new therapeutics is an immediate requirement. Lapatinib and everolimus have been demonstrated to be effective in the treatment of several carcinomas. This preclinical study aimed to investigate the effect and mechanism of lapatinib combined with everolimus on NPC cells. METHODS The Cell Co...

BACKGROUND Glioblastoma multiforme (GBM), the most common form of brain cancer with an average survival of less than 12 months, is a highly aggressive and fatal disease characterized by survival of glioma cells following initial treatment, invasion through the brain parenchyma and destruction of normal brain tissues, and ultimately resistance to current treatments. Temozolomide (TMZ) is commonl...

Cytoplasmic initiator tRNAs from plants and fungi possess an unique 2'-phosphoribosyl residue at position 64 of their sequence. In yeast tRNA(iMet), this modified nucleotide located in the T-stem of the tRNA is a 2'-1''-(beta-O-ribofuranosyl-5''-phosphoryl)-adenosine. The phosphoribosyl residue of this modified nucleoside was removed chemically by treatment involving periodate oxidation of tRNA...

The theoretical and computational description of materials properties is a task utmost scientific technological importance. A first-principles electron-electron interactions poses an immense challenge that usually approached by converting the many-electron problem to effective one-electron problem. There are different ways obtain exact theory for system. An emergent method electron factorizatio...
