background: nandrolone decanoate (nd) is an anabolic androgenic steroid (aas) which influences the ovarian structure and function. we assessed the effects of nd on the ovarian volume, number of primordial follicles, and level of hormones and also evaluated the modulatory effects of gonadotropins on the histopathological changes imposed by the administration of nd. methods: six groups of sprague...

NMR well logging of petroleum reservoir require the measurement of the NMR response of water, oil, and gas in the pore space of rocks at elevated temperatures and pressures. The viscosity of the oil may range from less than 1 cp to greater than 10,000 cp. Also, the oil and gas are not a single component but rather a broad distribution of components. The log mean T1 and T2 relaxation time of dea...

This paper provides an introduction to the ARK Smart Information System (SIS). It describes the business context in whichthe technology was conceived, and how the system addresses those needs. It outlines the important technology principles, and thebenefits of adopting such principles in a business environment. Finally it discusses the relevance of the technology to the thinkingbehi...

A hybrid numerical model previously developed for combustion simulations is extended in this article to describe flame propagation and stabilization porous media. The model, with a special focus on flame/wall interaction processes, validated via corresponding benchmarks involving channels both adiabatic constant-temperature walls. Simulations different channel widths show that the can correctly...

Gle1p is an essential, nuclear pore complex (NPC)-associated RNA export factor. In a screen for high copy suppressors of a GLE1 mutant strain, we identified the FG-nucleoporin Rip1p and the DEAD-box protein Rat8p/Dbp5p, both of which have roles in RNA export; we also found Ymr255p/Gfd1p, a novel inessential protein. All three high copy suppressors interact with the C-terminal domain of Gle1p; i...

introduction: various methods have been used for the treatment of dentine hypersensitivity such as dentifrices, sealants and different types of lasers. the aim of this study was to evaluate the effect of neodimium:yttrium-aluminium-garnet (nd:yag) laser in association with graphite on the dentin morphologic changes. methods: in this experimental in vitro study, 16 freshly extracted third molars...

Transduction of developmental and environmental cues into the nucleus to induce transcription and the export of RNAs to the cytoplasm through the nuclear pore complex (NPC) play pivotal roles in regulation of gene expression. The process of bulk export of mRNAs from nucleus to cytoplasm is highly conserved across eukaryotes. Assembly of export-competent mRNA ribonucleoprotein (mRNP) is coupled ...

Biological processes may provide great and previously unexplored opportunities for cost-effective, in situ improvement of the engineering properties of soil. A laboratory study was conducted to evaluate the changes in geomechanical properties of sand attributable to the formation of calcium precipitates induced through ureolysis catalyzed by Sporosarcina pasteurii (S. pasteurii). Specifically, ...
