Acanthamoeba species are the causative agents of fatal granulomatous encephalitis in humans. Haematogenous spread is thought to be a primary step, followed by blood–brain barrier penetration, in the transmission of Acanthmaoeba into the central nervous system, but the associated molecular mechanisms remain unclear. Here, we evaluated the role of Src, a(More)
Acanthamoeba isolation from extreme environments suggests that they may play a role in regulating archaeal densities and contribute to these ecosystems. The purpose of this study was to determine whether Acanthamoeba grow on extremophilic/mesophilic Archaea that are dominant cellular organisms in such environments. Sulfolobus solfataricus P2 and Sulfolobus(More)
Intravesical Bacillus Calmette-Guérin (BCG) is an established treatment for high-risk superficial bladder cancer [Morales A, Eidinger D, Bruce AW. Intracavitary Bacillus Calmette-Guérin in the treatment of superficial bladder tumors.1976. J Urol 2002; 167: 891-893, Lamm DL, van der Meijden APM, Morales A et al. Incidence and treatment of complications of(More)
— Due to recent substantial development in the field of wireless communication, there is a need to maximize spectral efficiency so that the extensive increase in traffic can be accommodated efficiently. Smart antenna system is a major source to maximize spectral efficiency and capacity of the wireless networks. It consists of an adaptive antenna array that(More)
In the face of harsh conditions and given a choice, a cell may (i) undergo programmed cell death, (ii) transform into a cancer cell, or (iii) enclose itself into a cyst form. In metazoans, the available evidence suggests that cellular machinery exists only to execute or avoid programmed cell death, while the ability to form a cyst was either lost or never(More)
Here we determined the role of various genomic islands in E. coli K1 interactions with phagocytic A. castellanii and nonphagocytic brain microvascular endothelial cells. The findings revealed that the genomic islands deletion mutants of RS218 related to toxins (peptide toxin, α -hemolysin), adhesins (P fimbriae, F17-like fimbriae, nonfimbrial adhesins, Hek,(More)
Over the past decade, wireless communications has seen an exponential growth and will certainly continue to witness spectacular developments due to the emergence of new interactive multimedia applications and highly integrated systems driven by the rapid growth in information services and microelectronic devices. So far, most of the current mobile systems(More)
Proteases are well-known virulence factors that promote survival, pathogenesis and immune evasion of many pathogens. Several lines of evidence suggest that the blood–brain barrier permeability is a prerequisite in microbial invasion of the central nervous system. Because proteases are frequently associated with vascular permeability by targeting junctional(More)
Today, Coarse Grained Reconfigurable Architectures (CGRAs) host multiple applications, with arbitrary communication and computation patterns. Compile-time mapping decisions are neither optimal nor desirable to efficiently support the diverse and unpredictable application requirements. As a solution to this problem, recently proposed architectures offer(More)
In this paper the performance of Cooperative-Cognitive Networks is analyzed using the Double Threshold Energy Detection algorithm. Introducing Double Threshold Energy Detection improves the spectrum detection accuracy and also it reduces the noise uncertainty. Monte Carlo Simulation is performed to show the significant improvement in the performance of(More)
