In this paper, we study the category of quantale-valued preordered spaces. We show that it is a normalized topological and give characterization zero-dimensionality D-connectedness in Moreover, characterize explicitly each T0, T1, pre-T2, T2 NT2 Finally, examine how these are related to other full subcategory Ti(pre-T2(L-Prord)) (i=0,1,2) pre-T2(L-Prord), Ti (L-Prord) (i=1,2) L-Prord isomorphic.

We used a surface-based analysis of T2* relaxation rates at 7 T magnetic resonance imaging, which allows sampling quantitative T2* throughout the cortical width, to map in vivo the spatial distribution of intracortical pathology in multiple sclerosis. Ultra-high resolution quantitative T2* maps were obtained in 10 subjects with clinically isolated syndrome/early multiple sclerosis (≤ 3 years di...

Introduction: In the evaluation of articular cartilage, cartilage repair and OA, biochemical magnetic resonance imaging (MRI) plays an important role. Different biochemical methods are exploited for their potential use at 1.5 Tesla and 3.0 Tesla in various studies and recently in clinical routine protocols (1). Advances in coil-technology significantly improve their ability for the diagnosis of...

The attentional blink (AB) represents a cognitive deficit in reporting the second of two targets (T2), when that second target appears 200-600 msec after the first (T1). However, it is unclear how this paradigm impacts the subjective visibility (that is, the conscious perception) of T2, and whether the temporal profile of T2 report accuracy matches the temporal profile of subjective visibility....

PURPOSE To develop a heart-rate independent breath-held joint T1 -T2 mapping sequence for accurate simultaneous estimation of coregistered myocardial T1 and T2 maps. METHODS A novel preparation scheme combining both a saturation pulse and T2 -preparation in a single R-R interval is introduced. The time between these two pulses, as well as the duration of the T2 -preparation is varied in each ...

In vitro poly(dA) synthesis on poly(dT) template can be initiated by poly(A) primer. Poly(A) chains are covalently extended by DNA polymerase. The reaction product consists of poly(dA) chain with poly(A) at their 5'-ends, hydrogen bonded to the template poly(dT). The primer poly(A) is linked to the product poly(dA) via a 3':5'-phosphodiester bond, and can be specifically removed by ribonuclease...

RNase MRP is a site-specific endoribonuclease that processes primer RNA from the leading-strand origin of mammalian mitochondrial DNA replication. It is present in active form as isolated from the nucleus, suggesting a bipartite cellular location and function. The relatively high abundance of nucleus-localized RNase MRP has permitted its purification to near homogeneity and, in turn, has led to...

The RNA component of the RNase P complex is found throughout most branches of the tree of life and is principally responsible for removing the 5' leader sequence from pre-tRNA transcripts during tRNA maturation. RNase P RNA has a number of universal core features, however variations in sequence and structure found in homologs across the tree of life require multiple Rfam covariance search model...

The endoribonuclease RNase P is involved in the processing of tRNA precursors to generate mature 5' termini. The catalytic activity of RNase P is associated with an RNA, RNase P RNA. A specific interaction between the 3' end of the substrate and RNase P RNA, to form an RNase P RNA-substrate complex, is referred to as the '73-294-interaction'. This interaction has an important role for efficient...
