Fumonisins are mycotoxins produced by Fusarium species and affecting maize crops. Some analogues of fumonisins are known for their toxic and possible carcinogenic effects on humans and animals. Because of their occurrence in corn-based food, diet is the main source of exposure to these mycotoxins, especially among people affected by celiac disease. Hence, the purpose of this paper was to evaluate the amount of fumonisins B1, B2 and B3 in maize-based products and to assess the exposure of people affected by celiac disease to fumonisins...

BACKGROUND: Digital high speed videomicroscopy(DHSV) allows analysis of ciliary beat frequency(CBF) and pattern(CBP) of respiratory cilia in 3 planes. Normal reference data use a sideways edge to evaluate ciliary dyskinesia, and calculate CBF using the time for a cilium to complete 10 beat cycles. Variability in CBF within respiratory epithelium has been described, but data concerning variation of CBP is limited in healthy epithelium. This study aims to document variability of CBP within normal samples, to compare ciliary function in 3 profiles, and CBF calculated over 5 or 10 beat cycles...

BACKGROUND: Hypomagnesemia is one of the characteristic side effects of the human anti-epidermal growth factor receptor (EGFR) monoclonal antibodies, cetuximab and panitumumab. The major mechanism of anti-EGFR antibody-related hypomagnesemia is suppression of EGFR-mediated urinary Mg(2+) reabsorption in both the renal tubule the intestinal tract. Since Mg(2+) is known to affect blood Ca(2+) levels through regulation of parathyroid hormone (PTH) secretion, we investigated the correlation between Ca(2+) and Mg(2+) concentration in blood...

A quenching mechanism mediated by the orange carotenoid protein (OCP) is one of the ways cyanobacteria protect themselves against photooxidative stress. Here, we present a femtosecond spectroscopic study comparing OCP and RCP (red carotenoid protein) samples binding different carotenoids. We confirmed significant changes in carotenoid configuration upon OCP activation reported by Leverenz et al. (Science 348:1463-1466. doi: 10.1126/science.aaa7234 , 2015) by comparing the transient spectra of OCP and RCP. The most important marker of these changes was the magnitude of the transient signal associated with the carotenoid intramolecular charge-transfer (ICT) state...

UNLABELLED: Zika virus (ZIKV) is a flavivirus that has emerged as a global health threat due in part to its association with congenital abnormalities. Other globally relevant flaviviruses include dengue virus (DENV) and West Nile virus (WNV). High-resolution structures of ZIKV reveal many similarities to DENV and suggest some differences, including an extended glycan loop (D. Sirohi, Z. Chen, L. Sun, T. Klose, T. C.

We explored the hypothesis that sorafenib may improve the effect of transarterial chemoembolization (TACE) in patients with recurrent hepatocellular carcinoma (HCC) and that longer sorafenib duration was associated with additional survival benefits. In this retrospective, nested case-controlled study, 1126 cases of unresectable HCC were collected. Patients with unresectable disease treated with TACE+sorafenib (n=245) and TACE alone (n=245) and those with recurrence after surgery treated with TACE+sorafenib (n=127) and TACE alone (n=127) were identified and matched according to sex, age, and lesion size and number...

We propose a scheme to detect the diffusive cloak proposed by Schittny et al. [Science345, 427 (2014).SCIEAS0036-807510.1126/science.1254524]. We exploit the fact that diffusion of light is an approximation that disregards wave interference. The long-range contribution to intensity correlation is sensitive to the locations of path crossings and the interference inside the medium, allowing one to detect the size and position, including the depth, of the diffusive cloak. Our results also suggest that it is possible to separately manipulate the first- and the second-order statistics of wave propagation in turbid media...

Single electron oxidation of amines provides an efficient way to access synthetically useful α-aminoalkyl radicals as reactive intermediates. After the single electron oxidation of amines, fragmentation of the resulting radical cations proceeds to give the α-aminoalkyl radicals along with generation of a proton. In the synthetic utilization of the α-aminoalkyl radicals, precise control of single electron transfer is essential, because further oxidation of the α-aminoalkyl radicals occurs more easily than the starting amines and the α-aminoalkyl radicals are converted into the corresponding iminium ions...

PURPOSE: Catheter ablation of atrial fibrillation (CAAF) using the cryoballoon has emerged as an alternate strategy to point-by-point radiofrequency. However, there is little comparative data on long-term durability of pulmonary vein (PV) isolation comparing these two modalities. METHODS: In this multicenter, retrospective analysis, the incidences/patterns of late PV reconnection following an index CAAF using the second-generation cryoballoon versus open-irrigated, non-force-sensing radiofrequency were examined...

Optical computing has emerged as a promising candidate for real-time and parallel continuous data processing. Motivated by recent progresses in metamaterial-based analog computing [Science343, 160 (2014)SCIEAS0036-807510.1126/science.1242818], we theoretically investigate the realization of two-dimensional complex mathematical operations using rotated configurations, recently reported in [Opt. Lett.39, 1278 (2014)OPLEDP0146-959210.1364/OL.39.001278]. Breaking the reflection symmetry, such configurations could realize both even and odd Green's functions associated with spatial operators...

BACKGROUND/AIMS: Although high serum alkaline phosphatase (ALP) levels were reported as predictive factors for death risk in dialysis patients on the basis of large databank analyses, the real scenario in a single hemodialysis (HD) center is unknown. METHODS: In this study, a 5-year cohort of 1126 prevalent HD patients in the largest HD center in Taiwan was studied. The associations of ALP levels expressed as baseline, time-average, and time-dependent with all-cause mortality and cardiovascular mortality were evaluated by using adjusted Cox regression models...

: Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a powerful biotyping tool increasingly used for high-throughput identification of clinical microbial isolates, however, in food fermentation research this approach is still not well established. This study examines the microbial biodiversity of cocoa bean fermentation based on the isolation of micro-organisms in cocoa-producing regions, followed by MALDI-TOF MS in Switzerland. A preceding 6-week storage test to mimic lengthy transport of microbial samples from cocoa-producing regions to Switzerland was performed with strains of Lactobacillus plantarum, Acetobacter pasteurianus and Saccharomyces cerevisiae...

In the present study, the full-length cDNA sequences of leptin (LEP) and its receptor (LEPR) from turbot Scophthalmus maximus were cloned. The cDNA of tLEP was 1126 bp in length encoding 157 amino acids. The amino acid sequence shared low identity with human LEP (18.8 %), but the three-dimensional structures of these two LEPs were strongly conserved. The deduced 1173-amino acid sequence of tLEPR was 28 % identical to human LEPR, and 82 % too range-spotted grouper LEPR, containing all functionally important domains conserved in vertebrate LEPR...
