A series of diurnal airborne campaigns were conducted over an orchard field to assess the canopy Photochemical Reflectance Index (PRI) as an indicator of water stress. Airborne campaigns over two years were conducted with the Airborne Hyperspectral Scanner (AHS) over an orchard field to investigate changes in PRI, in the Transformed Chlorophyll Absorption in Reflectance Index (TCARI) normalized...

While functional mature microRNAs (miRNAs) are small ∼22 base oligonucleotides that target specific mRNAs, miRNAs are initially expressed as long transcripts (pri-miRNAs) that undergo sequential processing to yield the mature miRNAs. We have previously reported that the pri-miR-17∼92 cluster adopts a compact globular folded structure that internalizes a 3' core domain resulting in reduced miRNA...

Periodic pulse trains can represent the emissions of a pulsed source or the \look" pattern of a scanning receiver. The distribution in time of pulse overlaps is considered for two strictly periodic pulse trains. The probability of at least one pulse overlap within a given time is found for a periodic pulse train with a staggered or jittered pulse train. These questions are important in understa...

MicroRNA (miRNA) biogenesis proceeds from a primary transcript (pri-miRNA) through the pre-miRNA into the mature miRNA. Here, we identify a role of the Caenorhabditis elegans nuclear export receptor XPO-1 and the cap-binding proteins CBP-20/NCBP-2 and CBP-80/NCBP-1 in this process. The RNA-mediated interference of any of these genes causes retarded heterochronic phenotypes similar to those obse...

OBJECTIVES The purpose of this study was to assess the in vitro P2Y12 receptor inhibitory effects of cangrelor on platelets from patients on maintenance prasugrel therapy treated with 2 reloading dose regimens. BACKGROUND Despite its more potent and rapid antiplatelet effects compared with clopidogrel, recent studies have shown variability in prasugrel-mediated P2Y12 receptor inhibition, part...

Background and Purpose. The recovery of walking after a stroke is a key functional goal for many patients. Reports vary, but approximately 50–80% of patients will regain some degree of walking ability following stroke (Skilbeck et al., 1983). There are few data available to show whether different subclassifications of stroke have distinct patterns of gait recovery. The present paper describes t...

The Transforming Growth Factor-β (TGF-β) signaling pathway is one of the major pathways essential for normal embryonic development and tissue homeostasis, with anti-tumor but also pro-metastatic properties in cancer. This pathway directly regulates several target genes that mediate its downstream functions, however very few microRNAs (miRNAs) have been identified as targets. miRNAs are modulato...

microRNAs (miRNAs) are known to play an essential role in controlling a broad range of biological processes including animal development. Accordingly, many miRNAs are expressed preferentially in one or a small number of cell types. Yet the mechanisms responsible for this selectivity are not well understood. The aim of this study was to elucidate the molecular basis of cell-specific expression o...

BACKGROUND Early post-transplantation alterations in liver tests are caused by a variety of etiologies including rejection, biliary or vascular complications, and preservation/reperfusion injury (PRI). OBJECTIVES The aim of this study was to show the correlation between histopathologic changes of PRI and the alterations in liver tests in the early post-transplantation period. MATERIALS AND ...
