Numerical modeling of heart valves using resistive Eulerian surfaces
Authors: Laadhari Aymen , Quarteroni Alfio 
Published: August 2015

SummaryThe goal of this work is the development and numerical implementation of a mathematical model describing the functioning of heart valves. To couple the pulsatile blood flow with a highly deformable thin structure (the valve's leaflets), a resistive Eulerian surfaces framework is adopted. A lumped‐parameter model helps to couple the movement of the leaflets with the blood dynamics. A reduced circulation model describes the systemic hemodynamics and provides a physiological pressure profile at the downstream boundary of the valve. The resulting model is relatively simple to describe for a healthy valve and pathological heart valve functioning while featuring an affordable computational burden. Efficient time and spatial discretizations are considered and implemented. We address in detail the main features of the proposed method, and we report several numerical experiments for both two‐dimensional and three‐dimensional cases with the aim of illustrating its accuracy.

Published: August 2015

AbstractThe pharmacokinetics (PK) of dapagliflozin and metformin administered as fixed‐dose combination (FDC) tablets (2.5 mg dapagliflozin/850 mg metformin or 5 mg dapagliflozin/1000 mg metformin) or as separate tablets in healthy subjects were evaluated in 2 separate studies. Study 1 evaluated PK by measuring mean ratios of area under the plasma concentration–time curve (time zero to infinity [AUCinf]), AUC from zero to time of last measurable concentration (AUC0–t), and maximum observed plasma concentration (Cmax) for single‐component or FDC tablets following a non‐high‐fat meal. Mean ratios of AUCinf, AUC0–t, and Cmax for FDC or single‐component dapagliflozin and metformin tablets were close to unity. In study 2, AUCinf, AUC0–t, and Cmax for the FDC tablet were obtained fasting and after a high‐fat meal. Dapagliflozin 5 mg and metformin 1000 mg geometric mean Cmax was increased in the fasted versus fed state (61.9 vs 43.9 and 1600 vs 1330 ng/mL, respectively), but AUC0–t was similar (267 and 265 and 11 000 and 10 600 ng · h/mL, respectively). In summary, FDC tablets were bioequivalent to single‐component tablets, and total absorption (AUC) was similar for non‐high‐fat and high‐fat meals.
A Density Functional Study of the Nonlinear Optical Properties of Edge‐Functionalized Nonplanar Nanographenes
Authors: Dai Yafei , Li Zhenyu , Yang Jinlong 
Published: August 2015

AbstractThe atomically precise edge chlorination of nanographenes has recently been reported as a crucial technology of functionalization through which the planar structure and optical properties of nanographenes can be significantly changed. To check the effects of molecular size, geometrical symmetry and edge functionalization of nanographenes on their optical properties, a series of nanographenes is studied in the framework of density functional theory with the B3LYP functional. Our results indicate that edge functionalization remarkably changes the nonlinear optical properties and increases the anisotropy of nanographenes compared to the effects of the molecular size and system geometric symmetry. Furthermore, the nonlinear optical properties of nanographenes can be tuned by precise edge functionalization, which opens a new avenue for using nanographenes as nonlinear optical materials.
Mechanostability of the Single‐Electron‐Transfer Complexes of Anabaena Ferredoxin–NADP+ Reductase
Authors: Marcuello Carlos , de Miguel Rocío , Martínez‐Júlvez Marta , Gómez‐Moreno Carlos , Lostao Anabel 
Published: August 2015

AbstractThe complexes formed between the flavoenzyme ferredoxin–NADP+ reductase (FNR; NADP+=nicotinamide adenine dinucleotide phosphate) and its redox protein partners, ferredoxin (Fd) and flavodoxin (Fld), have been analysed by using dynamic force spectroscopy through AFM. A strategy is developed to immobilise proteins on a substrate and AFM tip to optimise the recognition ability. The differences in the recognition efficiency regarding a random attachment procedure, together with nanomechanical results, show two binding models for these systems. The interaction of the reductase with the natural electron donor, Fd, is threefold stronger and its lifetime is longer and more specific than that with the substitute under iron‐deficient conditions, Fld. The higher bond probability and two possible dissociation pathways in Fld binding to FNR are probably due to the nature of this complex, which is closer to a dynamic ensemble model. This is in contrast with the one‐step dissociation kinetics that has been observed and a specific interaction described for the FNR:Fd complex.

Published: August 2015

ABSTRACTClustering of acetylcholine receptors (AChR) at the postsynaptic membrane is a crucial step in the development of neuromuscular junctions (NMJ). During development and after denervation, aneural AChR clusters form on the sarcolemma. Recent studies suggest that these receptors are critical for guiding and initiating synaptogenesis. The aim of this study is to investigate the effect of agrin and laminin‐1; agents with known AChR clustering activity; on NMJ formation and muscle maturation. Primary myoblasts were differentiated in vitro on collagen, laminin or collagen and laminin‐coated surfaces in the presence or absence of agrin and laminin. The pretreated cells were then subject to innervation by PC12 cells. The number of neuromuscular junctions was assessed by immunocytochemical co‐localization of AChR clusters and the presynaptic marker synaptophysin. Functional neuromuscular junctions were quantitated by analysis of the level of spontaneous as well as neuromuscular blocker responsive contractile activity and muscle maturation was assessed by the degree of myotube striation. Agrin alone did not prime muscle for innervation while a combination of agrin and laminin pretreatment increased the number of neuromuscular junctions formed and enhanced acetylcholine based neurotransmission and myotube striation. This study has direct clinical relevance for treatment of denervation injuries and creating functional neuromuscular constructs for muscle tissue repair. © 2015 Wiley Periodicals, Inc.

Prospective separation and transcriptome analyses of cortical projection neurons and interneurons based on lineage tracing by Tbr2 (Eomes)‐GFP/Dcx‐mRFP reporters

Published: August 2015

ABSTRACTIn the cerebral cortex, projection neurons and interneurons work coordinately to establish neural networks for normal cortical functions. While the specific mechanisms that control productions of projection neurons and interneurons are beginning to be revealed, a global characterization of the molecular differences between these two neuron types is crucial for a more comprehensive understanding of their developmental specifications and functions. In this study, using lineage tracing power of combining Tbr2(Eomes)‐GFP and Dcx‐mRFP reporter mice, we prospectively separated intermediate progenitor cell (IPC)‐derived neurons (IPNs) from non‐IPC‐derived neurons (non‐IPNs) of the embryonic cerebral cortex. Molecular characterizations revealed that IPNs and non‐IPNs were enriched with projection neurons and interneurons, respectively. Expression profiling documented cell‐specific genes including differentially expressed transcriptional regulators that might be involved in cellular specifications, for instance, our data found that SOX1 and SOX2, which were known for important functions in neural stem/progenitor cells, continued to be expressed by interneurons but not by projection neurons. Transcriptome analyses of cortical neurons isolated at different stages of neurogenesis revealed distinct temporal patterns of expression of genes involved in early‐born or late‐born neuron specification. These data present a resource useful for further investigation of the molecular regulations and functions of projection neurons and interneurons. © 2015 Wiley Periodicals, Inc.

1,25‐Dihydroxy‐vitamin D3 regulates NK‐cell cytotoxicity, cytokine secretion, and degranulation in women with recurrent pregnancy losses

Published: August 2015

Vitamin D has a pivotal role in regulating immune responses by promoting Th2 immune responses and suppressing Th1 responses. Propensities to a Th1 immune response and increased NK‐cell levels and cytotoxicity have been reported in women with recurrent pregnancy losses (RPL). In women with RPL, vitamin D deficiency is prevalent; however, the effect of vitamin D on NK cells is largely unknown. In this study, we demonstrated that CD69+ activating receptor expression on NK cells was significantly decreased by incubation with 1,25(OH)2D3 in a dose‐dependent manner, while CD158a and CD158b inhibitory receptor expression was upregulated. The degranulation marker CD107a was significantly downregulated on NK cells following incubation with 1,25(OH)2D3. NK‐cell conjugation with K562 target cells was not affected by 1,25(OH)2D3; however, depolarization of perforin granules in conjugated NK cells was significantly increased. TLR4 expression on NK cells was significantly decreased and TNF‐α and IFN‐γ production was significantly reduced by 1,25(OH)2D3 through interference with NF‐κB. Our results suggest 1,25(OH)2D3 has immune regulatory effects on NK cell cytotoxicity, cytokine secretion and degranulation process as well as TLR4 expression. Potential therapeutic application of 1,25(OH)2D3 for dysregulated NK‐cell immunity should be explored in the future.
Non‐Condensed (Oxo)Nitridosilicates: La3­[SiN4]F and the Polymorph o‐La3­[SiN3O]O
Authors: Durach Dajana , Schnick Wolfgang 
Published: August 2015

AbstractThe isotypic compounds La3[SiN4]F and La3[SiN3O]O were synthesized in a radio‐frequency furnace at 1600 °C. The crystal structures [Pnma (no. 62), Z = 4; La3(SiN4)F: a = 9.970(3), b = 7.697(2), c = 6.897(2) Å, V = 529.3(3) Å3; La3(SiON3)O: a = 9.950(2), b = 7.6160(15), c = 6.9080(14) Å, V = 523.48(18) Å3] were elucidated from single‐crystal X‐ray diffraction data and corroborated by Rietveld refinement, lattice‐energy calculations (Madelung part of lattice energy, MAPLE) and Raman/FTIR spectroscopy. Both compounds are homeotypic with Na2Pr[GeO4]OH forming a network of vertex‐sharing FLa6/OLa6 octahedra, whose voids are filled with non‐condensed SiN4/SiN3O tetrahedra. o‐La3[SiON3]O is the orthorhombic polymorph of this compound, which probably represents the high‐temperasture modification, whereas the tetragonal polymorph t‐La3[SiON3]O represents the low‐temperature modification. While the space group of the t‐polymorph [I4/mcm (no. 140)] differs from the new La3[SiN4]F and o‐La3[SiN3O]O, the crystal structure contains the same linking pattern.
