BACKGROUND Acute dyspnea and hypoxemia are 2 of the most common problems in the emergency room. Oxygen therapy is an essential supportive treatment to correct these issues. In this study, we investigated the physiologic effects of high-flow nasal oxygen cannula (HFNC) compared with conventional oxygen therapy (COT) in subjects with acute dyspnea and hypoxemia in the emergency room. METHODS A ...

This paper propose and predict the need for a new line of computer production that can facilitate and accelerate the improvements of things and systems towards IoT networks. The proposed computer that is named Computer of Thing, CoT, will speed up the establishment of smart world in a synchronized way with similar standards, communication protocols, and hardware and software. Also, the need for...

This article examines the potential of a learning-as-a-part-of-a-community approach, focusing on the participatory process of learning in a community-based, teacher education program; a Community of Teachers (CoT). CoT is a preparation program for preservice teachers working toward secondary teacher certification in which they join an on-going community and remain a part of that community from ...

A gas chromatography-mass spectrometry method was developed and validated for the simultaneous automated solid-phase extraction and quantification of cotinine and trans-3-hydroxycotinine in human urine. Good linearity was observed over the concentration ranges studied (R(2) > 0.99). The limit of quantification was 10 ng/mL for both analytes. The limits of detection were 0.06 ng/mL for cotinine ...

Studies were conducted to determine the herbicidal site of clomazone action in tolerant-soybean (Glycine max [L.] Merr. cv Corsoy) (SB-M) and susceptible-cotton (Gossypium hirsutum [L.] cv Stoneville 825) (COT-M) photomixotrophic cell suspension cultures. Although a 10 micromolar clomazone treatment did not significantly reduce the terpene or mixed terpenoid content (microgram per gram fresh we...

Carnitine octanoyltransferase (COT) purified from rat liver microsomes has K0.5 values between 1.0 and 4.0 microM for saturated 6-carbon to 16-carbon length acyl-CoAs, with little differences in Vmax values. The reaction rate is linear with time in the forward direction (acyl-CoA-->acylcarnitine), but it increases with time when assayed in the reverse direction (acylcarnitine-->acyl-CoA). The K...

Carnitine octanoyltransferase (COT) transports medium-chain fatty acids through the peroxisome. During isolation of a COT clone from a rat liver library, a cDNA in which exon 2 was repeated, was characterized. Reverse transcription-PCR amplifications of total RNAs from rat liver showed a three-band pattern. Sequencing of the fragments revealed that, in addition to the canonical exon organizatio...

BACKGROUND The challenge of responding to prescription opioid overuse within the United States has fallen disproportionately on the primary care clinic setting. Here we describe a framework comprised of 6 Building Blocks to guide efforts within this setting to address the use of opioids for chronic pain. METHODS Investigators conducted site visits to thirty primary care clinics across the Uni...

The increase intransplacental exchange depends primarily on the great development of the placental vascular bed. The aim of this study was to evaluate the pattern of placental vascular development at day 50 and 100 of pregnancy in goats and the relationship with the vascular endothelial growth factor (VEGF) immunolocalization. The placental morphometric variables: capillary area density, capill...

We report the results of a study on the effectiveness of Cot filtration (CF) in the characterization of the gene space of bread wheat (Triticum aestivum L.), a large genome species (1C = 16,700 Mb) of tremendous agronomic importance. Using published Cot data as a guide, 2 genomic libraries for hexaploid wheat were constructed from the single-stranded DNA collected at Cot values > 1188 and 1639 ...
