A meta‐analysis of pica and micronutrient status
Authors: Miao Diana , Young Sera L. , Golden Christopher D.
Published: August 2014

Objectives

Pica is the craving for and consumption of nonfood items, including the ingestion of earth (geophagy), raw starch (amylophagy), and ice (pagophagy). Pica has long been associated with micronutrient deficiencies, but the strength of this relationship is unclear. We aimed to evaluate the association between pica behavior and the risk of being anemic or having low hemoglobin (Hb), hematocrit (Hct), or plasma zinc (Zn) concentrations.

Methods

We systematically reviewed studies in which micronutrient levels were reported by pica status. We calculated the pooled odds ratio for anemia or weighted mean difference in Hb, Hct, or Zn concentrations between groups practicing or not practicing pica behaviors.

Results

Forty‐three studies including 6,407 individuals with pica behaviors and 10,277 controls were identified. Pica was associated with 2.35 times greater odds of anemia (95% CI: 1.94–2.85, P < 0.001), lower Hb concentration (−0.65 g/dl, 95% CI: −0.83 to −0.48 g/dl, P < 0.001), lower Hct concentration (−1.15%, 95% CI: −1.61 to −0.70%, P < 0.001), and lower Zn concentration (−34.3 μg/dl, 95% CI: −59.58 to −9.02 μg/dl, P = 0.008). Statistical significance persisted after excluding outliers and in subgroup analyses by pica type and life stage.

Conclusion

Pica is significantly associated with increased risk for anemia and low Hb, Hct, and plasma Zn. Although the direction of the causal relationship between pica and micronutrient deficiency is unknown, the magnitude of these relationships is comparable to other well‐recognized causes of micronutrient deficiencies. Pica warrants greater public health attention; specifically the potential physiological mechanisms underpinning the relationship between pica and micronutrient deficiencies merit further study. Am.

A combined attributes–variables plan
Authors: Govindaraju K. , Kissling R.
Published: August 2014

The design of single sampling plans in which the lot acceptance decision is based on both variables and attribute measurement of quality is discussed. A new plan, called the combined attributes–variables plan, is proposed incorporating an acceptance number to the regular variables plan for consumer protection. A design approach for the new plan is also developed for food manufacturing applications in which the sample size cannot be predetermined because of short production lengths and other analytical testing issues.

Exploratory analysis of an optimal variable speed control system for a recurrently congested freeway bottleneck
Authors: Yang Xianfeng , Lu Yang (Carl) , Chang Gang‐Len
Published: August 2014

This study presents two models for proactive variable speed limit (VSL) control on a recurrently congested freeway segment. The proposed model uses embedded traffic flow relations to predict the evolution of congestion patterns over the projected time horizon, and then computes the time‐varying optimal speed limit to smooth traffic flows. To contend with the uncertainties associated with drivers' responses to VSL control, this study has also proposed an advanced model that further adopts Kalman Filter to enhance the traffic state estimation. Both models have been investigated with two control objectives—travel time minimization and speed variance minimization. Our extensive simulation analysis with a VISSIM simulator, calibrated with field data from our previous VSL field demonstration, has revealed the benefits of the proposed VSL control models. Also, the experimental results indicated that the proposed advanced models with both control objectives can significantly reduce the travel time over the recurrent bottleneck locations. With respect to several selected measure of effectiveness (MOEs), such as average number of stops and average travel time, the research results confirm that the control models with the objective of minimizing speed variance can offer the promising properties for field implementation.

Molekül‐ und Gitterschwingungen des orthorhombischen und ferroelektrischen Thioharnstoffs: II. Berechnung der innermolekularen und zwischenmolekularen Kraftkonstanten
Authors: Bleckmann Von P. , Schrader B. , Meier W. , Takahashi H.
Published: August 2014

Die Frequenzen und Bewegungsformen der in den Infrarot‐ und Raman‐Spektren des kristallinen Thioharnstoffs auftretenden Schwingungen der Elementarzellen werden unter Berücksichtigung der Schwingungszustände der Moleküle und des Gitters berechnet. Die Potentialfunktionen enthalten für die inneren Schwingungen der Moleküle Kraftkonstanten eines allgemeinen Valenzkraftfeldes, für die äußeren Molekülschwingungen (Gitterschwingungen) werden lediglich Valenzkraftkonstanten in Richtung aller zwischenmolekularen Atomabstände mit Werten kleiner als 3,4 Å zugrundegelegt. Die nach unseren Berechnungen ermittelten Kraftkonstanten für die H···H‐Abstände stimmen mit denjenigen überein, die von Shimanouchi theoretisch begründet und angewandt wurden [1, 3]. Die Schwingungsfrequenzen des Thioharnstoffs im Bereich von 700 bis 1370 cm−1 können keinen bestimmten inneren Koordinaten einzeln zugeordnet werden. Sie verteilen sich über die C – N‐ und C – S‐Valenzschwingungen sowie Deformationsschwingungen des Gerüstes und der NH2‐Gruppen. Auch bei den Schwingungen mit niedrigen Frequenzen (<550 cm−1) kann man klar zwischen den inneren Schwingungen und denjenigen, die zum überwiegenden Teil von zwischenmolekularen Kräften abhängen, unterscheiden, obwohl die Lagen einiger innerer Schwingungen auch von zwischenmolekularen Kräften abhängig sind und die Frequenzen der Gitterschwingungen von inneren Kraftkonstanten der Moleküle mitbestimmt werden. Die beobachteten Temperaturabhängigkeiten sowie die Faktorgruppen‐Aufspaltungen werden von der Theorie qualitativ gut wiedergegeben.
Untersuchungen zur Oxydation von 1‐Phenylpyrazolidon(3) und seinem 5,5‐Dimethylderivat: II. Struktur der Reaktionsprodukte und Reaktionsmechanismus
Authors: Vogel Von D. , Jaenicke W.
Published: August 2014

Mit Hilfe der IR‐, Massen‐, Elektronenanregungs‐ und Elektronenresonanzspektren werden die Konstitution und der Bildungsmechanismus des violetten Produkts untersucht, das bei der Stabilisierung der Primärradikale von 1‐Phenyl‐5,5‐dimethylpyrazolidon(3) entsteht. Im geschwindigkeitsbestimmenden Schritt reagiert der Amidstickstoff eines Primärradikals mit dem Phenylende eines zweiten unter Bildung eines neuen Radikals. Diesem Schritt folgt eine homologe Polymerisation, die bis zum Polymerisationsgrad 5 nachweisbar ist. Bei der Eliminierung des H am Phenylrest bilden sich gleichzeitig die entsprechenden am Stickstoff hydrierten Verbindungen. Diese lassen sich mit Diphenylpikrylhydrazyl unter Rückbildung der violetten Radikale titrieren. Die Radikale gehören zum Typ der Goldschmidtschen Hydrazyle. Analoge Reaktionen treten als Nebenreaktionen bei anderen 1‐Phenyl‐pyrazolidonen auf.

Mechanism of Formation and Dissociation of Nickel‐II‐thiocyanate and Nickel‐II‐chloride Complexes in Dimethyl Sulfoxide [1]
Authors: Dickert F. , Hoffmann H.
Published: August 2014

The solutions of Ni(SCN)2 and NiCl2 in dimethyl sulfoxide were investigated with a pressure jump apparatus and a shocktube. The rate constants of formation and dissociation for the mono‐complexes of Ni(SCN)2 and NiCl2 were determined. In the case of the more stable complex Ni(SCN)2, two relaxation times were found and so the evaluation of the rate constants of the bis‐complex was possible. According to Eigen's association mechanism the results are interpreted. The estimated dimethyl sulfoxide exchange rate from the nickel ion is in good agreement with NMR data. The dimethyl sulfoxide exchange rate is accelerated by a coordinated thiocyanate ligand by a factor of ten.

Authors: Tomchuk E. , Czubryt J. J. , Chatterjee N. , Bock E.
Published: August 2014

A deuteron spin‐lattice relaxation study of the water‐dioxane system has been carried out. It was found that the deuteron relaxation results were in complete agreement with the conclusions derived from proton spin‐lattice relaxation studies, reported earlier, viz: the microdynamical environment of the dioxane molecule in dilute aqueous solutions is strongly concentration dependent and is closely related to the solution viscosity. It was also found that the quadrupole coupling constant of deuterated dioxane is concentration independent and has a value of 175 kHz and 171 kHz in pure dioxane and in infinitely dilute aqueous solution respectively.
Incorporating alternative splicing and mRNA editing into the genetic analysis of complex traits
Authors: Hassan Musa A. , Saeij Jeroen P. J.
Published: August 2014

The nomination of candidate genes underlying complex traits is often focused on genetic variations that alter mRNA abundance or result in non‐conservative changes in amino acids. Although inconspicuous in complex trait analysis, genetic variants that affect splicing or RNA editing can also generate proteomic diversity and impact genetic traits. Indeed, it is known that splicing and RNA editing modulate several traits in humans and model organisms. Using high‐throughput RNA sequencing (RNA‐seq) analysis, it is now possible to integrate the genetics of transcript abundance, alternative splicing (AS) and editing with the analysis of complex traits. We recently demonstrated that both AS and mRNA editing are modulated by genetic and environmental factors, and potentially engender phenotypic diversity in a genetically segregating mouse population. Therefore, the analysis of splicing and RNA editing can expand not only the regulatory landscape of transcriptome and proteome complexity, but also the repertoire of candidate genes for complex traits.
Dissecting post‐mating prezygotic speciation phenotypes
Authors: Shaw Kerry L. , Lambert Jonathan M.
Published: August 2014

Darwin's “mystery of mysteries,” the origin of species, is caused by the evolution of speciation phenotypes, i.e. phenotypic differences that depress gene flow between daughter species during speciation. Postmating, prezygotic (PMPZ) differentiation characterizes many closely related species causing conspecific sperm precedence (CSP), wherein a female preferentially utilizes conspecific over heterospecific sperm in fertilization. Until recently, the components of CSP have been difficult to observe and study in internally fertilizing organisms. Research into the mechanisms of CSP is now progressing rapidly with the help of new innovative research tools. With the recent development of a sperm labeling system enabling distinct labels for different males, direct observations of competing male sperm within the female reproductive tract are possible, revealing multiple PMPZ phenotypes that combine to cause CSP. The discovery of mechanisms underlying CSP predicts an exciting future for studies of PMPZ speciation phenotypes and possible general principles underlying the origin of species.
Replication protein A: Single‐stranded DNA's first responder
Authors: Chen Ran , Wold Marc S.
Published: August 2014

Replication protein A (RPA), the major single‐stranded DNA‐binding protein in eukaryotic cells, is required for processing of single‐stranded DNA (ssDNA) intermediates found in replication, repair, and recombination. Recent studies have shown that RPA binding to ssDNA is highly dynamic and that more than high‐affinity binding is needed for function. Analysis of DNA binding mutants identified forms of RPA with reduced affinity for ssDNA that are fully active, and other mutants with higher affinity that are inactive. Single molecule studies showed that while RPA binds ssDNA with high affinity, the RPA complex can rapidly diffuse along ssDNA and be displaced by other proteins that act on ssDNA. Finally, dynamic DNA binding allows RPA to prevent error‐prone repair of double‐stranded breaks and promote error‐free repair. Together, these findings suggest a new paradigm where RPA acts as a first responder at sites with ssDNA, thereby actively coordinating DNA repair and DNA synthesis.
Biological Applications of Expanded Genetic Codes
Authors: Li Xiang , Liu Chang C.
Published: August 2014

Substantial efforts in the past decade have resulted in the systematic expansion of genetic codes, allowing for the direct ribosomal incorporation of ∼100 unnatural amino acids into bacteria, yeast, mammalian cells, and animals. Here, we illustrate the versatility of expanded genetic codes in biology and bioengineering, focusing on the application of expanded genetic codes to problems in protein, cell, synthetic, and experimental evolutionary biology. As the expanded genetic code field continues to develop, its place as a foundational technology in the whole of biological sciences will solidify.
Friedel–Crafts Alkylation of Indoles Exclusively in Water Catalyzed by Ionic Liquid Supported on a Polyacrylonitrile Fiber: A Simple “Release and Catch” Catalyst
Authors: Shi Xian‐Lei , Lin Huikun , Li Pengyu , Zhang Wenqin
Published: August 2014

A series of ionic liquids supported on polyacrylonitrile fibers (FSILs) served as “release and catch” catalysts to mediate the Friedel–Crafts alkylation of indoles exclusively in water. Detailed characterization by elemental analysis, FTIR spectroscopy, and SEM confirmed that a significant amount of ionic liquid was immobilized on the surface layer of the fiber, and excellent results, in terms of the simple procedure, high yields (87–96 %), and superior catalytic recyclability (over 10 cycles), are reported for the metal and cosolvent‐free synthesis of a wide variety of bis(indolyl)methanes at room temperature. The reason why the reaction catalyzed with FSILs only proceeded in water is explained, and a “release and catch” catalytic mechanism is proposed. Moreover, the procedures can be scaled up efficiently, and the solvent can be recovered and reused without contamination. The prominent features of the fiber catalyst are very attractive for fixed‐bed reactors in the chemical industry.
The Mtr Pathway of Shewanella oneidensis MR‐1 Couples Substrate Utilization to Current Production in Escherichia coli
Authors: TerAvest Michaela A. , Zajdel Tom J. , Ajo‐Franklin Caroline M.
Published: August 2014

Introducing an electronic interface into Escherichia coli will allow its enormous synthetic biology toolkit to be leveraged in bioelectrochemical applications. While E. coli expressing the Mtr pathway of Shewanella oneidensis MR‐1 transfer electrons to an anode, it has remained unclear if this current production alters the intracellular state of E. coli, which is a critical requirement for bioelectronic technologies. Here we address this by characterizing current production in Mtr‐expressing E. coli and its effects on cellular viability, substrate consumption, and product generation. We found that cymA‐mtr E. coli sustained ∼8‐fold higher current levels than a control strain. This increased current production did not change E. coli viability or substrate consumption, but it did alter metabolic fluxes. A shift to more oxidized products strongly suggests that the Mtr pathway improves redox balance in E. coli. By demonstrating the Mtr module couples current production to intracellular state, this work establishes Mtr‐expressing E. coli as a platform for accelerated development of bioelectronic technologies.

Published: August 2014

(Dibenzoylmethanato)boron difluoride derivatives containing triphenylamine moieties were synthesized as a new type of electron‐donor/π‐acceptor system. These new compounds exhibited long‐wavelength absorptions in the UV/Vis spectra, and reversible oxidation and reduction waves in cyclic voltammetry experiments. Their amphoteric redox properties are based on their resonance hybrid forms, in which a positive charge is delocalized on the triphenylamine moieties and a negative charge is localized on the boron atoms. Molecular orbital (MO) calculations indicate that their HOMO and LUMO energies vary with the number of phenylene rings connected to the difluoroboron‐chelating ring. This is useful for optimizing the HOMO and LUMO levels to an iodine redox (I−/I3−) potential and a titanium dioxide conduction band, respectively. Dye‐sensitized solar cells fabricated by using these compounds as dye sensitizers exhibited solar‐to‐electric power conversion efficiencies of 2.7–4.4 % under AM 1.5 solar light.
Rapid Assembly of Functionalised Spirocyclic Indolines by Palladium‐Catalysed Dearomatising Diallylation of Indoles with Allyl Acetate
Authors: Dhankher Persis , Benhamou Laure , Sheppard Tom D.
Published: August 2014

Herein, we report the application of allyl acetate to the palladium‐catalysed dearomatising diallylation of indoles. The reaction can be carried out by using a readily available palladium catalyst at room temperature, and can be applied to a wide range of substituted indoles to provide access to the corresponding 3,3‐diallylindolinines. These compounds are versatile synthetic intermediates that readily undergo Ugi reactions or proline‐catalysed asymmetric Mannich reactions. Alternatively, acylation of the 3,3‐diallylindolinines with an acid chloride or a chloroformate, followed by treatment with aluminium chloride, enables 2,3‐diallylindoles to be prepared. By using ring‐closing metathesis, functionalised spirocyclic indoline scaffolds can be accessed from the Ugi products, and a dihydrocarbazole can be prepared from the corresponding 2,3‐diallylindole.
Alkali‐Metal Ion Catalysis and Inhibition in SNAr Displacement: Relative Stabilization of Ground State and Transition State Determines Catalysis and Inhibition in SNAr Reactivity
Authors: Um Ik‐Hwan , Cho Hyo‐Jin , Kim Min‐Young , Buncel Erwin
Published: August 2014

We report here the first observation of alkali‐metal ion catalysis and inhibition in SNAr reactions. The plot of kobsd versus [alkali‐metal ethoxide] exhibits downward curvature for the reactions of 1‐(4‐nitrophenoxy)‐2,4‐dinitrobenzene with EtOLi, EtONa, and EtOK, but upward curvature for the corresponding reaction with EtOK in the presence of 18‐crown‐6‐ether (18C6). Dissection of kobsd into the second‐order rate constants for the reactions with the dissociated EtO− and the ion‐paired EtOM (i.e., k and kEtOM, respectively) has revealed that the reactivity increases in the order EtOLi<EtONa<EtOK<EtO−<EtOK/18C6. This indicates that the reaction is inhibited by Li+, Na+, and K+ ions but is catalyzed by 18C6 K+ ion. The reactions of 1‐(Y‐substituted‐phenoxy)‐2,4‐dinitrobenzenes have been proposed to proceed through a stepwise mechanism, in which expulsion of the leaving group occurs after the rate‐determining step based on the kinetic result that σo constants exhibit a much better Hammett correlation than σ− constants. Alkali‐metal ion catalysis or inhibition has been discussed in terms of differential stabilization of ground‐state and transition‐state complexes through a qualitative energy profile. A π‐complexed transition‐state structure is proposed to account for the kinetic results.

The synthesis, full characterization, photoreduction properties, and catalytic activity for the copper(I)‐catalyzed alkyne‐azide cycloaddition (CuAAC) reaction of a copper(II)–DMEDA (N,N′‐dimethylethylendiamine) complex is reported. Spectroscopic studies (UV/Vis, EPR) demonstrated that under daylight illumination highly effective copper(II) to copper(I) reduction occurs in this complex. These findings are in agreement with a high photoreduction quantum yield value of 0.22 in MeOH, and a value approaching unity as determined in THF. The reduction process, which can also be conducted by irradiation at 365 nm by using a standard TLC (thin layer chromatography) lamp, is ascribed to a highly efficient photoinduced electron transfer (PET) process mediated by the benzophenone photosensitizer present in the carboxylate counterion. Having deaerated the reaction mixture, the photogenerated copper(I) species proved to be highly active for the CuAAC reaction, demonstrated by reactions conducted with low catalyst loading (0.5 mol %) on a range of clickable protected and non‐protected mono‐ and disaccharides. Once initiated, the reaction can be stopped at any time on introducing air into the reaction medium. Deoxygenation followed by irradiation restores the activity, making the copper(II)–DMEDA complex a switchable catalyst of practical value.
