Over half (56%) had an NT of up to 3.5mm, 33% were between 3.5mm-5mm and 11% were over 5mm, with a mean DQ of 108.4, 110.1 and 109.7, respectively. CONCLUSION Infants with prenatal and isolated increased NT, in the first trimester, had a significantly lower, but normal, developmental quotient at a corrected age of 2 years, when compared to the controls. The findings were independent of sex, NT thickness and mothers' education. This article is protected by copyright. All rights reserved. This article is protected by copyright.

We are interested in the synthesis of protein-mimics containing triazole linkages as peptide-bond surrogate by topochemical azide-alkyne cycloaddition (TAAC) polymerization of azide- and alkyne-modified peptides. The rationally designed dipeptide N3 -CH2 CO-Phe-NHCH2 CCH (1) crystallized in a parallel β-sheet arrangement and are head-to-tail aligned in a direction perpendicular to the β-sheet-direction. Upon heating, crystals of 1 underwent single-crystal-to-single-crystal polymerization forming a triazole-linked pseudoprotein with Gly-Phe-Gly repeats. During TAAC polymerization, the pseudoprotein evolved as helical chains. These helical chains are laterally assembled by backbone hydrogen bonding in a direction perpendicular to the helical axis to form helical sheets. This interesting helical-sheet orientation in the crystal resembles the cross-α-amyloids, where α-helices are arranged laterally as sheets. © 2020 Wiley-VCH Verlag GmbH & Co.

METHODS We conducted electronic searches in PubMed, Embase and Cochrane Central Register of Controlled Trials from January 1960 to July 2019 to identify RCTs that examined the effects of febuxostat in adult patients with hyperuricemia on serum creatinine, estimated glomerular filtration rate (eGFR), albuminuria, blood pressure parameters, major cardiovascular events, diarrhea, joint pain, stroke, and arrhythmia. RESULTS Nine RCTs with 2141 participants were included in this meta-analysis. Compared to placebo, the febuxostat group showed a higher eGFR at 6 months with a weighted mean difference (WMD) of 2.86 mL/min/1.73 m2 (p less then  0.001), as well as the end of studies (eGFR WMD 2.69 mL/min/1.73m2 , p less then  0.001). There was also lower serum creatinine (SrCr WMD = -0.04 mg/dL p less then  0.001), reduction in systolic blood pressure (SBP WMD = -1.18 mmHg, p less then  0.001), and diastolic blood pressure (DBP WMD = -1.14 mmHg, p = 0.04). There was no statistical difference between febuxostat and placebo in major cardiovascular events, diarrhea, joint symptoms, stroke events, and arrhythmia. Subgroup analysis among chronic kidney disease showed the febuxostat group had higher eGFR than the placebo group (eGFR WMD = 2.69 mL/min/1.73m2 , p less then  0.001). CONCLUSION Treating hyperuricemia with febuxostat may slow the progression of CKD irrespective of baseline renal function without significantly associated increased risks of major cardiovascular events, diarrhea, joint symptoms, arrhythmia, and stroke, compared to placebo.

This sequence consists of three processes (1) interrupted Pummerer reaction to form S-O-tethered sulfonium salt, (2) C-C-forming [3,3] sigmatropic rearrangement with dearomatization, and (3) Zn-mediated defluorinative rearomatization. The present biaryl construction provides a facile access to polyfluorinated biaryls that is difficult to synthesize by other methods. The synthetic utility of the strategy is clearly demonstrated by the synthesis of a fluorinated analogue of Maxipost, a potassium channel modulator. © 2020 WILEY-VCH Verlag GmbH & Co.

Imaging pathogens in their natural environment takes a more holistic view on biomedical aspects of parasitic infections. Here, we focus on selected organs of the thoracic and abdominopelvic cavities most commonly affected by parasites. Parasitic infections of these organs are often associated with severe medical complications or have health implications beyond the infected individual. Intravital imaging has provided a more dynamic picture of the host-parasite interplay and contributed not only to our understanding of the various disease pathologies but has also provided fundamental insight into the biology of the parasites.

Studies have shown that non-synonymous SNPs in 5-hydroxytryptamine(serotonin or 5 -HT)are related to primary insomnia. Previous studies have shown that 5 -HT polymorphism (rs140700) is related to depression, and insomnia is often accompanied by depression and anxiety. The relationship between this site and primary insomnia is unknown. We speculated that this site may be related to primary insomnia, so we investigated the relationship between rs140700 and primary insomnia. METHODS In this study, we included 57 patients with primary insomnia and 54 age- and gender-matched normal controls. The subjects belonged to the Chinese population were subjected to polysomnography for three consecutive nights. Their sleep quality was assessed, and the genotypes of the 5-HT gene polymorphism rs140700 were determined by the Flight Mass Spectrometry. RESULTS The genotype distributions of the 5-HTgene polymorphism rs140700 were in Hardy-Weinberg equilibrium in both patients and controls (P > 0.05). The allele and genotype distributions of this variant were comparable between the patients and controls in all subjects and between genders (all P > 0.05). The influence of rs140700 on S1% (P = 0.015) change and arousal index(P = 0.028) of primary insomnia was statistically significant. The logistic multi-factor regression analysis results revealed that 5-HT gene polymorphism rs140700 was not a risk factor for primary insomnia in Chinese population (P = 0.589). CONCLUSION The 5-HT gene polymorphism rs140700 may not be a susceptibility locus for primary insomnia in the Chinese population. This article is protected by copyright. All rights reserved.
