Total (i.e. free+sulfated) metanephrines in plasma is a biomarker for the diagnosis of pheochromocytoma/paraganglioma. Sulfated metanephrines must be completely deconjugated by perchloric acid hydrolysis or sulfatase treatment prior to analytical measurement to enable quantification by current techniques. In this report we compare the yield and efficiency of both methods. Deconjugation ...

Prior studies have shown that applications of the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D) to the foliage of potato plants can reduce common scab. Here field and glasshouse trials suggest that 2,4-D foliar treatments may also reduce the biologically distinct tuber disease, powdery scab. Significant correlations between suppression of common and ...

Bioinvasions are a significant force of change--and economic and ecological threat--in marine ecosystems. The threat now encroaches on Alaska, which has had relatively few invasions compared to other global regions, prompting need to develop new incursion response tools. We appraised five 'eco-friendly' immersion treatment options (dilute acetic acid, dilute bleach, ...

A low rate of mitochondrial ROS production (mitROSp) and a low degree of fatty acid unsaturation are characteristic traits of long-lived animals and can be obtained in a single species by methionine restriction (MetR) or atenolol (AT) treatments. However, simultaneous application of both treatments has never been performed. In the ...

6-Substituted amino-penicillanic acid esters were synthesized starting with 6-apa. The compounds containing a 1,3-thiazole- or 1,3-thiazolidinone nucleus linked to the penicillanic acid skeleton via a hydrazino linkage were obtained from 6-apa. The treatment of carbonylamino and carbonothioylamino compounds with 4-chlorophenacyl bromide or ethyl bromoacetate gave 6-bis{4-[1,3-thiazol(idinone)amino]benzoyl}amino derivatives of 6-apa. Benzyl ...

Methoxytropolones are useful scaffolds for therapeutic development due to their known biological activity. Upon treatment with triflic acid, a series of 3-methoxy-8-oxabicyclo[3.2.1]octa-3,6-dien-2-ones rearrange rapidly and cleanly to form methoxytropolones. Interestingly, bicyles that are derived from dimethyl acetylenedicarboxylate instead form furans as the major product.
