However, the validation is a challenging work due to the lack of gold-standard. This study proposed an evaluation framework by using point-to-point displacement vector field (DVF). Three DIR algorithms including original flow, active Demons and symmetric force Demons were validated for ten lung 4D CT images with landmarks. DVFs derived from DIR algorithms (dDVF) and manually measured according to landmarks (mDVF) were analyzed and compared. Their target registration errors (TRE) and the relationship of lung motion and three-dimensional TRE were explored. The distance discordance metric (DDM) values were calculated. For all cases, the active Demons algorithm had the smallest TRE value and DDM values and it showed the poor correlation between 3D TRE and lung motion, which indicated that this algorithm outperformed other DIR algorithms enrolled in this study. Preliminary results demonstrated that the proposed...

Findings: In this multinational prospective birth cohort consisting of 6,605 genetically predisposed children, higher gluten intake was associated with a statistically significant increase of celiac disease autoimmunity (HR 1.30, 95% CI 1.22-1.38) and celiac disease (HR 1.50, 95% CI 1.35-1.66), for every gram increase of gluten intake per day. Meaning: Increased intake of gluten during the first 5 years of life was an independent risk factor of celiac disease autoimmunity and celiac disease in genetically predisposed children.

The MoS2 nanosheets were obtained using a simple ultrasonic method from bulk MoS2. The physical adsorption between MoS2 and aromatic XA monomers effectively improved the electropolymerization efficiency, accompanied with an increased electrochemical response of PXA. The obtained PXA/MoS2 nanocomposite not only served as a substrate for DNA immobilization but also reflected the electrochemical transduction originating from DNA immobilization and hybridization without any complex labelling processes or outer indicators. The immobilization of the probe ssDNA was achieved via noncovalent assembly due to the π-π interaction between PXA and DNA bases. After the hybridization of the probe ssDNA with the target DNA, the formation of helix structure induced the resulted dsDNA to be released from ...

Hence, it is an essential work to estimate the real-time movement of target in radiation therapy. BP-NN has been widely used in respiratory motion prediction due to its superior non-linear fitting capability. However, BP-NN is easy to fall into local minimum. In this study anovel method using PSO to optimize the BP-NN was proposed to avoid its drawbacks and improve prediction accuracy. The preliminaryresultsof 6 patients demonstrate that the proposed method (PSO-NN) has the ability of improving the prediction accuracy of BP-NN method.

A maximum output power of 814 mW was obtained by a 972-nm commercial laser diode, and the corresponding slope efficiency was 30.4%. Laser emission under 1532-nm excitation was also achieved by efficient upconversion energy transfers. This could be an effective technique for realizing a compact and efficient upconversion laser capable of emitting in the mid-infrared regime.

We investigated the association between maternal use of vitamin D, n-3 fatty acids (FA) and Fe supplements during pregnancy and risk for CD autoimmunity (CDA) and CD in the offspring. Children at increased genetic risk were prospectively followed from birth in The Environmental Determinants of Diabetes in the Young (TEDDY) study. CDA was defined as having persistently positive tissue transglutaminase autoantibodies (tTGA). Diagnosis of CD was either biopsy-confirmed or considered likely if having persistently elevated levels of tTGA>100 AU. Of 6627 enrolled children, 1136 developed CDA at a median 3·1 years of age (range 0·9-10) and 409 developed CD at a median 3·9 years of age (range 1·2-11). Use of supplements containing vitamin D, n-3 FA and Fe was recalled by 66, 17 and 94 % of mothers, respectively, at 3-4 months postpartum. The mean cumulative intake over the entire pregnanc...

We investigated whether gluten intake before 2 years of age increases risk for celiac disease in genetically susceptible children. We performed a case-control study of 436 pairs of children, generated from a database of 2525 children with genetic susceptibility to celiac disease in Sweden, matched for sex, birth year, and HLA genotype from September 2004 and February 2010. Children were screened annually for celiac disease using an assay for tissue transglutaminase autoantibodies (tTGA). Intestinal biopsies were collected from children who tested positive for tTGA to confirm the presence of celiac disease. Gluten intake was calculated from 3-day food records collected when the children were 9, 12, 18 and 24 months old. Breastfeeding duration (median 32 weeks) and age at first introduction to gluten (median 22 weeks) did not differ between cases and tTGA-negative children (controls). At the...

Hypoxia is a strong stimulus for new blood vessel formation or angiogenesis, which is essential for tumor growth and progression. Fibroblast growth factor 11 (FGF11) is an intracellular non-secretory FGF whose function has not yet been fully characterized. In the present study, we demonstrated that FGF11 expression is upregulated under hypoxic conditions in human umbilical vein endothelial cells (HUVECs). FGF11 overexpression stimulated capillarylike tube formation, yet did not affect cell migration. Notably, FGF11 markedly increased the levels of tight junction proteins including occludin, zonula occludens-1 (ZO-1) and claudin-5 in HUVECs. The FGF11 promoter contains hypoxia response elements (HREs), and hypoxia-inducible factor-1 (HIF-1) binds to HREs to activate hypoxia-related genes. We demonstrated that hypoxia or HIF-1 expression under normoxic conditions increased the luciferase activity driven by the FGF11 promoter. However, deletion of the HREs from the FGF11 promoter rendered reporter gene activity unresponsive to hypoxia or HIF-1. Taken together, we propose that FGF11 may be involved in the stabilization of capillary-like tube structures associated with angiogenesis and may act as a modulator of hypoxiainduced pathological processes such as tumorigenesis.

The reaction of LnCl 3 (or LnBr 3) with 1 in a 1:2 molar ratio in dry THF at 60°C produced the dimerized half-sandwich lanthanacarborane complexes [2,3-(SiMe 3) 2-1-X-1-(THF) m-1-Ln(η 5-2,3-C 2 B 4 H 4)] 2 ‚n(THF) (3, Ln) Y, X) Cl, m) 2, n) 1; 4, Ln) La, X) Br; m) 1, n) 0; 5, Ln) Ce, X) Br; m) 1, n) 0; 6, Ln) Pr, X) Br; m) 2, n) 1; 7, Ln) Nd; X) Cl, m) 2, n) 1; 8, Ln) Sm; X) Br, m) 2, n) 0; 9, Ln) Gd; X) Cl, m) 2, n) 1; 10, Ln) Tb, X) Cl, m) 2, n) 1; 11, Ln) Dy, X) Cl, m) 2, n) 1; 12, Ln) Ho, X) Cl, m) 2, n) 1; 13, Ln) Er, X) Cl, m) 2, n) 1; 14, Ln) Tm, X) Cl, m) 2, n) 1; 15, Ln) Yb, X) Cl, m) 2, n) 1; 16, Ln) Lu X) Cl, m) 2, n) 1) as crystalline solids in 70-92% isolated yields. In a similar manner, the reactions of 2 with LnCl 3 at 65°C gave the corresponding complexes [2-Me-3-(SiMe 3)-1-Cl-1-(THF) 2-1-Ln(η 5-2,3-C 2 B 4 H 4)] 2 (17, Ln) Nd; 18, Ln) Dy; 19, Ln) Ho; 20, Ln) Er; 21, Ln) Yb) as crystalline solids in 72-80% yield. In both series of the reactions, 1 equiv of the particular neutral carborane was also produced. The substitution of the chloride ions in complexes 17 and 20 by 2 gave the half-sandwich lanthanacarborane clusters {2-Me-3-(SiMe 3)-1-[4,5-(µ-H)-nido-2-Me-3-(SiMe 3)-2,3-C 2 B 4 H 5 ]-1-Ln(η 5-2,3-C 2 B 4 H 4)} 2 ‚n(THF) (22, Ln) Nd, n) 2; 24, Ln) Er, n) 1) as crystalline solids in 82-87% yield. The reaction of 19 and 2 produced the trimer {2-Me-3-(SiMe 3)-1-[4,5-(µ-H)-nido-2-Me-3-(SiMe 3)-2,3-C 2 B 4 H 5 ]-1-Ho(η 5-2,3-C 2 B 4 H 4)} 3 ‚8(THF) (23) in 57% yield. Complexes 22, 23, and 24 could directly be obtained in good yield (56-67%) from the reaction of 2 with the corresponding LnCl 3 at 65°C in molar ratios of 3:1 in dry THF. Similarly, the mixed coordinated complex {2,3-(SiMe 3) 2-1-[4,5-(µ-H)-(nido-2-Me-3-(SiMe 3)-2,3-C 2 B 4 H 5)]-1-Gd(η 5-2,3-C 2 B 4 H 4)} 2 ‚3(THF) (25) was obtained by reacting compound 9 with 2. To investigate the importance of the halide in these reactions, (η 5-Cp)LnCl 2 (Ln) Tb, Dy, Er) with 1 in a 1:2 molar ratio produced lanthanacarborane complexes [1-(η 5-C 5 H 5)-2,3-(SiMe 3) 2-1-Ln(η 5-2,3-C 2 B 4 H 4)] 2 ‚n(THF) (26, Ln) Tb, n) 2; 27, Ln) Dy, n) 2; 28, Ln) Er, n) 3) as crystalline solids in 77-82% isolated yields. On the other hand, the reactions of (η 5-Cp) 2 ErCl and (η 8-C 8 H 8)GdCl with 1 in 1:1 molar ratios did not produce the half-sandwich lanthanacarboranes, but rather gave the exo-polyhedral products {exo-(η 5-C 5 H 5) 2 Er[4,5-(µ-H)-2,3-(SiMe 3) 2-2,3-C 2 B 4 H 4 ]}‚(THF) (29) and {exo-(η 8-C 8 H 8)Gd[4,5-(µ-H)-2,3-(SiMe 3) 2-2,3-C 2 B 4 H 4 ]‚2(THF) (30) as crystalline solids in 76% and 73% isolated yield, respectively. All compounds were characterized by IR spectroscopy and elemental analysis, whereas compounds 3, 7-9, 10-16, 18-22, 29, and 30 were characterized by single-crystal X-ray diffraction studies. The diamagnetic compounds 3, 4, and 16 were additionally characterized by 1 H, 13 C, and 11 B NMR spectroscopy.
