Comprehensive expression profiles of Arabidopsis (Arabidopsis thaliana) MIRNA genes and mature microRNAs (miRs) are currently not available. We established a quantitative real-time polymerase chain reaction platform that allows rapid and sensitive quantification of 177 Arabidopsis primary miR transcripts (pri-miRs). The platform was used to detect phosphorus (P) or nitrogen (N) status-responsiv...

This paper presents a new feature set for the problem of recognizing pulse 10 repetition interval (PRI) modulation patterns. The recognition is based upon the features 11 extracted from the multiresolution decomposition of different types of PRI modulated 12 sequences. Special emphasis is placed on the recognition of jittered and stagger type PRI 13 sequences due to the fact that these types of...

DGCR8/Pasha is an essential cofactor for Drosha, a nuclear RNase III that cleaves the local hairpin structures embedded in long primary microRNA transcripts (pri-miRNAs) in eukaryotes. Although our knowledge of pri-miRNA processing has significantly advanced in recent years, the precise role of DGCR8 in this pathway remains unclear. In our present study, we dissect the domains in DGCR8 that con...

Structurally similar double-point modified analogues of 1,25-dihydroxyvitamin D₂ (1,25D₂) were screened in vitro for their pro-differentiating activity against the promyeloid cell line HL60. Their affinities towards human full length vitamin D receptor (VDR) and metabolic stability against human vitamin D 24-hydroxylase (CYP24A1) were also tested. The analogues (PRI-1730, PRI-1731, PRI-1732, PR...

While acute myocardial infarction (MI) is associated with impaired clopidogrel responsiveness, systematic evaluation is lacking due to the inability of functional aggregation-based assays to analyse clopidogrel responsiveness in the presence of glycoprotein IIb/IIIa inhibitors. Using the P2Y12-specific, non-aggregation-based platelet-reactivity-index (PRI) we assessed clopidogrel responsiveness...

Assessing photosynthesis rates with remote sensing is important for tracking the physiological state of plants. The photochemical reflectance index (PRI) is a good estimator of short-term light-use efficiency (LUE) at the leaf scale but its responses to environmental factors are poorly understood. In this study, we assessed changes in the responses of the PRI to ozone exposure and to an increas...

The active form of vitamin D3 and some of its related compounds show neuroprotective effects in various models of neuronal damage, however, mechanism of their anti-apoptotic action has not been elucidated. Therefore, the present study was designed to investigate the effects of 1,25-dihydroxyvitamin D3 and its low-calcemic analogues, PRI-2191, PRI-1890 and PRI-1901 on staurosporine-induced apopt...

Sashka’s Technique applied to pFBP The key step in Sashka and Russel’s technique to prove lower bounds for pFBT was to prove that for each path p of length l, PrI [S(I) ⊢ PSp | I ⊢ PIp] ≤ 1 f . We extend this to a technique for pFBP. The key step is to prove that for each node v at depth l, PrI [S(I) ⊢ PSv | I ⊢ PIv] ≤ 1 f . My intuition was that PrI [S(I) ⊢ PSv | I ⊢ PIv] ≤ maxp∈v PrI [S(I) ⊢ ...

Introduction. Few studies have examined the association between the PR interval (PRi) and subclinical cardiovascular disease measures. Methods and Results. The Multiethnic Study of Atherosclerosis (MESA) is a population-based study of 6814 men and women aged 45-84 years without clinical cardiovascular disease and 4962 had complete baseline data on cardiac magnetic resonance imaging measures of ...
