We present I/O-efficient fully persistent B-Trees that support range searches at any version in O(logB n + t/B) I/Os and updates at any version in O(logB n + log2 B) amortized I/Os, using space O(m/B) disk blocks. By n we denote the number of elements in the accessed version, by m the total number of updates, by t the size of the query’s output, and by B the disk block size. The result improves...
OBJECTIVES To conduct a fully independent, external validation of a research study based on one electronic health record database using a different database sampling from the same population. DESIGN Retrospective cohort analysis of β-blocker therapy and all-cause mortality in patients with cancer. SETTING Two UK national primary care databases (PCDs): the Clinical Practice Research Datalink...
The aim of this work was to study the in vitro release of piroxicam suspended in the internal phase of some W/O/W (water/oil/water) double emulsions and to investigate the effect of hydrophilic macromolecules (hydroxyethylcellulose and Carbopol 940) in the external aqueous phases of W/O/W double emulsions on the diffusion profiles of piroxicam through synthetic membranes. W/O/W double emulsions...
Subalpine grasslands are highly seasonal environments and likely subject to strong variability in nitrogen (N) dynamics. Plants and microbes typically compete for N acquisition during the growing season and particularly at plant peak biomass. During snowmelt, plants could potentially benefit from a decrease in competition by microbes, leading to greater plant N uptake associated with active gro...
We examined changes In the levels of dissolved inorganic nitrogen (DIN) during incubation experiments with 4 conspicuous sponge species from Caribbean coral reefs, mangroves, or seagrass beds (Chondrilla nucula, ?Pseudaxinella zeai, Oligoceras violacea, Plakortis halichondroides). DIN accumulation in the incubation water was detected for all the species, but no significant DIN concentration cha...
Dual epidermal growth factor receptor (EGFR) and HER2 targeting with the tyrosine kinase inhibitor lapatinib is approved for treating advanced HER2-positive breast cancer and can prevent estrogen receptor (ER)-negative mammary tumors in HER2 transgenic mouse models. Ki-67 labeling index (LI) has prognostic and predictive value and can be used to screen drugs' therapeutic and preventive potentia...
