The activation of the Wnt/β-catenin pathway protected against the impairment of intestinal permeability induced by maternal vitamin D deficiency. CONCLUSIONS Maternal vitamin D deficiency increased intestinal permeability and decreased tight junction protein expression in offspring. The suppression of the Wnt/β-catenin signaling pathway through histone modification might be involved in the underlying mechanism. © 2020 American Society for Parenteral and Enteral Nutrition.Calcium metal batteries (CMBs) provide a promising option for high-energy and cost-effective energy storage technology beyond current state-of-the-art lithium-ion batteries. Nevertheless, the development of room-temperature CMBs is significantly impeded by the poor reversibility and short lifespan of calcium metal anode. Herein we report a solvation manipulation strategy to improve the plating/stripping reversibility of calcium metal anode by enhancing the de-solvation kinetics of calcium ions in the electrolyte. The introduction of lithium salt greatly changes the electrolyte structure by reducing coordination number of calcium ions in the first solvation shell. As a result, an unprecedented Coulombic efficiency (CE) of calcium metal anode for galvanostatic plating/stripping is achieved up to 99.1%, accompanying with a very stable long-term cycling performance over 200 cycles at room temperature. This work may open up a new opportunity for developing practical calcium metal batteries. © 2020 WILEY-VCH Verlag GmbH & Co.

Overexpression of GRP78 on cancer cells makes this molecule a suitable candidate for cancer detection and targeted therapy. VHH is the binding fragment of camelid heavy chain antibodies also known as "nanobody". The aim of this study is to isolate and produce a new recombinant nanobody using phage display technique to detect cancer cells. MATERIAL AND METHODS Using the c-terminal domain of GRP78 (CGRP) as an antigen, four rounds of biopanning were performed, and high-affinity binders were selected by ELISA. Their affinity and functionality were characterized by surface plasmon resonance (SPR) cell ELISA and immunocytochemistry. RESULTS A unique nanobody named V80 was purified. ELISA and SPR showed that this antibody had high specificity and affinity to the GRP78. Immunofluorescence analysis showed that V80 could specifically bind to the HepG2 and A549 cancer cell lines. CONCLUSION This novel recombinant nanobody could bind to the cell surface of different cancer cells. After further evaluation, this nanobody can be used as a new tool for cancer detection and tumor therapy. This article is protected by copyright. All rights reserved.

The hydrophobic block of the copolymer is a random copolymer consisting of a spiropyran functionalized 2-oxazoline (SPOx) and 2-(but-3-yn-1-yl)-4,5-dihydrooxazole (ButynOx), while the hydrophilic block is based on 2-methyl-2-oxazoline (MeOx). The block copolymer is terminated with tris(2-aminoethyl) amine (TREN) that serves as catalyst in a Knoevenagel condensation. Four block copolymers with different ButynOx/SPOx and hydrophilic/hydrophobic ratios are synthesized and self-assembled through solvent exchange. read more Micelles and vesicles of various sizes are observed by TEM, which undergo morphological and size changes in response to irradiation with UV light. We hypothesize that these transformations in the nanostructures are caused by increases in the hydrophilicity of the hydrophobic block when spiropyran (SP) isomerizes to merocyanine (MC) in the presence of UV light. The reversible transition from micellar to vesicular nanoreactors resulted in increased reaction kinetics through improved substrate accessibility to the catalytic site, or termination of the catalytic reaction due to polymer precipitation. These nanoreactors present a promising platform towards photoregulating reaction outcomes based on changes in nanostructure morphology. © 2020 WILEY-VCH Verlag GmbH & Co.

RRD secondary to antibiotics has also been reported but is a rare phenomenon overall and there are no reports of RRD in association with ceftriaxone exposure. METHODS We report on a 59-year-old patient who had received radiotherapy to the neck bilaterally and who developed RRD 6 months later after a single dose of intramuscular ceftriaxone. RESULTS The patient's rash resolved without further intervention over the ensuing 2 days following administration of a single dose of ceftriaxone. CONCLUSION This case illustrates that while RRD secondary to antibiotic exposure is rare, it is part of the differential diagnosis to be considered for acute dermatitis when there is a past history of radiotherapy to the same skin area. © 2020 Wiley Periodicals, Inc.BACKGROUND Treatment of drinking water may decrease microbial exposure. OBJECTIVE To investigate whether bacterial load in drinking water is associated with altered risk of allergic diseases. METHODS We recruited 1,110 schoolchildren aged 6-16 years between 2011 and 2013 in Požega-Slavonia County in Croatia, where we capitalized on a natural experiment whereby individuals receive drinking water through public mains supply or individual wells. We obtained data on microbial content of drinking water for all participants; 585 children were randomly selected for more detailed assessments, including skin prick testing. Since water supply was highly correlated with rural residence, we compared clinical outcomes across four groups (Rural/Individual, Rural/Public, Urban/Individual and Urban/Public). For each child, we derived quantitative index of microbial exposure (bacterial load in the drinking water measured during the child's first year of life). RESULTS Cumulative bacterial load in drinking water was higher (median [IQR] 6390 [4190-9550] vs 0 [0-0]; P less then .
