A simple, rapid, in situ, and green extraction combined with a microcomplexation has been developed for the spectrophotometric determination of phosphate in water samples. Through their formation, layered double hydroxides (LDHs) were employed as the extraction medium, instantly commenced by a rapid addition of a mixed solution of Mg(2+) and Al(3+) ions into alkaline phosphate solution. After the extraction, LDH precipitate containing phosphate was dissolved by sulfuric acid and the released phosphate was subsequently detected via its complexation with molybdate in the presence of antimonyl and ascorbic acid...

The 3D structure determination of biological macromolecules by X-ray crystallography suffers from a phase problem: to perform Fourier transformation to calculate real space density maps, both intensities and phases of structure factors are necessary; however, measured diffraction patterns give only intensities. Although serial femtosecond crystallography (SFX) using X-ray free electron lasers (XFELs) has been steadily developed since 2009, experimental phasing still remains challenging. Here, using 7.0-keV (1...

The concept of dynamic single-interface hollow fiber membrane liquid-phase microextraction (HF-LPME), where the target analyte was extracted on-line and eluted inside the lumen of the HF membrane, was explored. An ionic liquid containing supported liquid membrane was used for the trace determination of Cr(VI) as a model compound. Since the extraction took place on-line inside the hollow fiber membrane, the mass transfer behavior was described and discussed in comparison with the conventional HF-LPME. The extraction efficiency was improved by a recirculation configuration of the sample solution at relatively high sampling flow rates as a result of the increased effective contact area...

Sacrococcygeal chordoma is a malignant tumour originating from remnants of the notochord. Chordomas are slow-growing tumours whose symptoms develop insidiously. We present the case of a 72-year-old woman with a 6-month history of genital pain radiating to the perianal area and exacerbating when she was in a sitting position. MRI and PET studies revealed a large mass in the sacrococcygeal region causing bone destruction and invasion of neurovascular structures. The immunohistochemical study of the surgical specimen determined it to be chordoma...

Recombinase mediated cassette exchange (RMCE) is a powerful tool for targeted insertion of transgenes. Here we describe non-proprietary 'RMCE-in' cell lines as an alternative to the 'Flp-in' system and cell lines. RMCE-in cell lines offer a number of advantages including increased efficiency of integration of the genetic element of interest (GEI) at a single docking site, lack of bacterial backbone at the docking site both before and after GEI integration, removal of selection and visual markers initially present at the docking site upon GEI integration and the possibility to validate GEI integration by loss of a red fluorescence reporter...

The production of heat, i.e., thermogenesis, is a significant component of the metabolic rate, which in turn affects weight gain and health. Thermogenesis is linked to physical activity (PA) level. However, it is not known whether intrinsic exercise capacity, aging, and long-term voluntary running affect core body temperature. Here we use rat models selectively bred to differ in maximal treadmill endurance running capacity (Low capacity runners, LCR and High capacity Runners, HCR), that as adults are divergent for aerobic exercise capacity, aging, and metabolic disease risk to study the connection between PA and body temperature...

DNA replication and chromosome segregation must be carefully regulated to ensure reproductive success. During Bacillus subtilis sporulation, chromosome copy number is reduced to two, and cells divide asymmetrically to produce the future spore (forespore) compartment. For successful sporulation, oriC must be captured in the forespore. New rounds of DNA replication are prevented in part by SirA, a protein that utilizes residues in its N-terminus to directly target Domain I of the bacterial initiator, DnaA. Using a quantitative forespore chromosome organization assay, we show that SirA also acts in the same pathway as another DnaA regulator, Soj, to promote oriC capture in the forespore...

Polyploidization events such as whole-genome duplication and inter-species hybridization are major evolutionary forces that shape genomes. Although long-term effects of polyploidization have been well-characterized, early molecular evolutionary consequences of polyploidization remain largely unexplored. Here, we report the discovery of two recent and independent genome hybridizations within a single clade of a fungal genus, Trichosporon Comparative genomic analyses revealed that redundant genes are experiencing decelerations, not accelerations, of evolutionary rates...

Metabolic pathway engineering in microbial hosts for heterologous biosynthesis of commodity compounds and fine chemicals offers a cheaper, greener, and more reliable method of production than does chemical synthesis. However, engineering metabolic pathways within a microbe is a complicated process: levels of gene expression, protein stability, enzyme activity, and metabolic flux must be balanced for high productivity without compromising host cell viability. A major rate-limiting step in engineering microbes for optimum biosynthesis of a target compound is DNA assembly, as current methods can be cumbersome and costly...

A conceptually new approach for an efficient removal of anionic organic dyes from wastewater using layered double hydroxides (LDHs) through their formation is presented. Acid yellow 25 (AY25) was used as anionic organic dye model molecules. As a result of the electrostatic induction, the removal mechanism involved a concurrent incorporation of AY25 molecules into the interlayer of LDHs during their structural arrangement, where Mg(2+) and Al(3+) ions were utilized to construct the base of LDHs in an alkaline solution...

INTRODUCTION: Chromosomal translocations at 2p23 cause overexpression of anaplastic lymphoma kinase (ALK), a receptor tyrosine kinase involved in signalling pathways that regulate cell proliferation. This translocation occurs in 5% of lung adenocarcinoma and has been demonstrated to be useful as a therapeutic target for crizotinib. sinonasal adenocarcinomas (SNAC) are histologically similar to lung adenocarcinomas; the aim of this study was to evaluate the presence of ALK alterations in SNAC...
