The global need for accurate and sensitive quantitation of microcystins (MCs) persists as incidents of cyanobacterial harmful algal blooms continue to rise and recent research reveals an underestimation of the human health implications of these toxins. An optimal approach for their accurate quantitation relies on the availability of stable isotope-labeled MC standards for use in stable isotope dilution analysis (SIDA) strategies involving liquid chromatography tandem mass spectrometry (LC-MS/MS). Due to the dearth of isotopically labeled MCs, ten different 15N-enriched MCs were biosynthesized from producing cultures and fully characterized...

Here we report the site-specific incorporation of a thioester containing non-canonical amino acid (ncAA) into recombinantly expressed proteins. Specifically, we genetically encoded a thioester-activated aspartic acid (ThioD) in bacteria in good yield and with high fidelity using an orthogonal nonsense suppressor tRNA/aminoacyl-tRNA synthetase (aaRS) pair. To demonstrate the utility of ThioD, we used native chemical ligation to label green fluorescent protein with a fluorophore in good yield.

Sesquiterpenes are a widespread class of compounds of increasing interest found in grapes and wines, amongst many other natural sources. Due to a lack of standards and the complexity of the mass spectra fragmentation, accurate quantification of these low concentration compounds had not previously been accomplished. The current paper presents a new method for the concurrent quantification of several sesquiterpenes. The multivariate method optimisation is presented. Synthesised isotopic standards were utilised in conjunction with solid phase microextraction (SPME) and gas chromatography-tandem mass spectrometry (GC-MS/MS) to perform a standard isotope dilution assay (SIDA)...

Aspergillus fumigatus is one of the major causes of invasive pulmonary aspergillosis in immunocompromised patients. Novel antifungal therapy is in urgent need due to emerging resistance and adverse toxicity of current antifungal drugs. Gene products that are essential for Aspergillus viability during infection are attractive drug targets. To characterize these genes in vivo we developed a Tet-Off gene expression system in A. fumigatus, whereby the administration of doxycycline resulted in down regulation of the gene whose expression is under the control of the Tet-Off promoter...

To determine the most suitable strategy in treating patients with invasive breast cancer from Northwest China. Lower recurrence score (RS) correlated with lower recurrence ratio. Patients having a medium-high 21-gene RS who received adjuvant therapy presented lower recurrence risk. Younger patients having RS results (⩾31) tended to accept adjuvant therapy more often, however, those having intermediate RS results were inclined to wait and did not receive chemotherapy. These results suggested that RS-based precision medicine will allow individualized diagnosis and treatment, resulting in better outcomes and preserved medical resources...

Radiolabeling of molecules or nanoparticles to form imaging probes is critical for positron emission tomography (PET) imaging, which, with high sensitivity and the ability for quantitative imaging, has been widely used in the clinic. While conventional radiolabeling often employs chelator molecules, a general method for chelator-free radiolabeling of a wide range of materials remains to be developed. Herein, we uncovered that ten different types of metal oxide (MxOy, M=Gd, Ti, Te, Eu, Ta, Er, Y, Yb, Ce, or Mo, x=1-2, y=2-5) nanomaterials with polyethylene glycol (PEG) modification could be labeled with 89Zr, a PET tracer, via a simple yet general chelator-free radiolabeling method upon simple mixing...
