Fruit Preserves and Jellies
Authors: DeGregorio Marnie L.
Published: July 2007

Fruit preserves and jellies date back to ancient times. The use of sugar widened the possibility of preserving fruits. The name, preserves, covers a broad range of products including jams, butters, marmalades, and conserves, as well as preserves. Gelation gives fruit preserves their texture. Gelation depends on pectin, sugar, acid, and water. Typical and novel gel systems are discussed. Information on the use of sugar and other sweeteners in preserves is given. Traditional and modern processing techniques are detailed. Overall quality of fruit preserves and jellies has improved due to improvements in processing. Fruit quality is the most important in the process of making preserves. Problems that arise in the process such as color changes, color fading, crystal formation, floating fruit, mold, etc, can be avoided. Trends are noted.

To assess the role of leukapheresis and cranial irradiation in reducing the incidence of intracranial hemorrhage (ICH) and early death in patients with hyperleukocytic acute myeloid leukemia (AML) and the impact of such treatment on survival. This study retrospectively analyzed the records of 75 patients with hyperleukocytic AML who had a white cell count over 100,000/μL. All patients had de novo AML except for two with therapy‐related AML. Various factors were assessed for their impact on morbidity and mortality, particularly the role of pre‐induction leukapharesis and cranial irradiation. The most significant risk factors for ICH were the presence of two or more symptoms of leukostasis (odds ratios [OR] 10.6, 95% CI: 2.67–42.02; P = 0.001) and respiratory distress (OR 5.41, 95% CI: 1.44–20.32, P = 0.012). The most significant risk factors for early death were age ≥ 65 (OR 4.21, 95% CI: 1.45–12.21, P = 0.008), respiratory failure (OR 3.34, 95% CI: 1.24–9.50, P = 0.018), and two or more symptoms (OR 3.50 95% CI: 1.16–10.52, P = 0.026). Neither leukapheresis nor cranial irradiation were significantly associated with a decreased incidence of ICH (P = 0.349 and 0.378, respectively). Leukapheresis had no significant influence on early death (P = 0.367). The median survival patients receiving no pretreatment was 10.50 months (range 2.58–18.42) and for those receiving pretreatment 1.50 months (range 0.10–3.16; log‐rank test, P = 0.062). Leukapheresis and cranial irradiation do not improve survival or decrease the incidence of ICH in adults with hyperleukocytic AML. Am. J. Hematol., 2007. © 2007 Wiley‐Liss, Inc.
Combined neonatal blood transplants in a parent‐to‐F1 mouse model: Improved survival rates and stable long‐term engraftment
Authors: Scaradavou Andromachi , Sung Dorothy , Rubinstein Pablo
Published: July 2007

The use of cord blood (CB) transplantation for adult patients is limited by the relatively low cell content of a single collection. Two, partially‐matched CB grafts could provide optimal cell doses. The interactions among the donor‐derived populations have not been fully evaluated. We used our mouse model (Neonatal peripheral blood––NPB––transplants to adult recipients) to evaluate whether grafts from two histocompatibility‐disparate donors (“combined” grafts) had higher survival and faster hematopoietic recovery than single donor transplants, each at suboptimal cell dose (leading to survival <<60%). Transplants were performed in a parent‐to‐F1 setting: NPB or bone marrow (BM) cells from the fully mismatched, homozygous parental strains (A/J, B6) were given to myeloablated B6AF1 recipients. Outcomes improved by combining NPB grafts: 48% of A/J graft recipients (1 × 106 cells/animal) survived; all animals transplanted with B6 (same cell dose) died. Survival after combined NPB transplants was 75% (P << 0.01) and recipients had accelerated recovery of WBCs and platelets compared to single donor A/J grafts (P << 0.01). No such improvements occurred with suboptimal dose combined BM transplants. Recipients of combined NPB grafts reconstituted with one donor primarily. Chimerism levels remained stable. Successful secondary transplants demonstrated long‐term persistence of both NPB grafts. Combined haplo‐identical NPB but not BM grafts, each transplanted at suboptimal cell doses, engraft synergistically leading to faster reconstitution. Although the mouse model does not fully represent the complex clinical aspects of human transplantation, our findings support the concept of using two CB grafts for adult patients when a sufficiently large single one is not available.

Published: July 2007

Rutheniumkatalysierte Olefinmetathesen sind leistungsfähige Reaktionen zur Bildung von Kohlenstoff‐Kohlenstoff‐Doppelbindungen. Das Gebiet ist mittlerweile gut erforscht, zumal zahlreiche Katalysatoren erhältlich sind, die vielfältige Umwandlungen ermöglichen. Trotzdem gibt es, mit der Ausnahme von Polymerisationsprozessen, nur wenige industrielle Anwendungen der Olefinmetathese. Dies hängt vor allem damit zusammen, dass die Endprodukte der Reaktion nur schwer von den Rutheniumspezies befreit werden können. Eine Reihe von Prozessen wurde entwickelt, um den Rutheniumkatalysator oder seine Abbauprodukte zu beseitigen, keines dieser Verfahren ist aber gänzlich zufriedenstellend. Ein neuer Ansatz, der seit kurzem intensiv verfolgt wird, ist die Verwendung verankerter Varianten von Homogenkatalysatoren. Dieser Aufsatz fasst die zahlreichen Studien zusammen, die auf die Entwicklung von nachhaltigeren rutheniumkatalysierten Metathesen abzielen.

Published: July 2007

Neuere Entwicklungen, die darauf abzielen, DNA als funktionelles Baumaterial für Nanoobjekte zu verwenden, zeigen vielversprechende Ergebnisse. In der Vergangenheit wurden molekulare DNA‐Nanoarchitekturen aus unmodifizierten oder bestenfalls endgruppenmodifizierten Oligonucleotiden aufgebaut, sodass derzeit die Entwicklung von funktionalisierten DNA‐Strukturen im Rampenlicht der Forschung steht. Eine der neuesten Entwicklungen in diese Richtung ist der Austausch der kanonischen Watson‐Crick‐Basenpaare durch Metallkomplexe zur Erzeugung von Metall‐Basenpaaren, die DNA‐Nanostrukturen magnetische oder elektrisch leitende Eigenschaften verleihen könnten. Dieser Kurzaufsatz fasst die Forschung auf diesem Gebiet zusammen, die vor fast 45 Jahren mit der Untersuchung der Interaktion von Metallen mit unmodifizierter DNA begann und nun ihren Höhepunkt in der Synthese künstlicher, ligandenähnlicher Nucleobasen findet, die bereits imstande sind, bis zu zehn Metallionen innerhalb eines einzelnen DNA‐Doppelstrangs programmierbar zu koordinieren.

Published: July 2007

A soluble bisphenol containing azomethine moiety and aromatic ether linkage, 2,2′‐bis {4‐[4‐(hydroxy) phenyliminomethylidene] phenoxyphenyl} propane (BHPP), was synthesized from the reaction of 4‐hydroxybenzaldehyde with 2,2′‐bis (4‐aminophenoxy phenyl) propane (BAPP) and characterized by IR, 1H NMR, 13C NMR, and elemental analysis. To improve the overall properties of epoxy/diamine thermoset, ternary‐curing systems combined BAPP/BHPP with diglycidyl ether of biphenyl A (DGEBA) were designed. It was found that the curing behavior and properties of the BAPP/DGEBA system changed dramatically due to the introduction of BHPP. The hybrid‐curing agents BAPP/BHPP exhibited more reactivity toward oxirane group than did BAPP. All the epoxy thermosets had high thermal properties, e.g., glass transition temperatures (Tgs) are between 145 and 170°C, 5% weight loss temperatures over 329°C, integral procedure decomposition temperature (IPDT) varied with 682–1085°C and good flame retardancy for their high limited oxygen index (LOI) values beyond 28.4. © 2007 Wiley Periodicals, Inc.

Lignocellulose conversion: an introduction to chemistry, process and economics
Authors: Lange Jean‐Paul
Published: July 2007

Governments across the world are stimulating the valorization of local biomass to secure the energy supply, reduce the emissions of fossil CO2 and support the rural economy. A first generation of fuels and chemicals is being produced from high‐value sugars and oils. Meanwhile, a second generation, based on cheaper and more abundant lignocellulosic feedstock, is being developed. This review addresses the variety of chemistries and technologies that are being explored to valorize lignocellulosic biomass. It shows the need to ‘deoxygenate’ the biomass and reviews the main chemical routes for it, i.e.

a) the pyrolysis to char, bio‐crude or gas;

b) the gasification to syngas and its subsequent conversion, e.g. to alkanes or methanol;

c) the hydrolysis to sugar and their subsequent upgrading to oxygenated intermediates via chemical or fermentation routes.

The economics of biomass conversion also needs to be considered: the current production cost of biofuels are typically $60–120/barrel of oil equivalent. Influential factors include the cost of the biomass at the plant gate, the conversion efficiency, the scale of the process and the value of the product (e.g. fuel, electricity or chemicals). © 2007 Society of Chemical Industry and John Wiley & Sons, Ltd

Published: July 2007

Five Kunitz protease inhibitor group B genes were isolated from the genome of the diploid non‐tuber‐forming potato species Solanum palustre. Three of five new genes share 99% identity to the published KPI–B genes from various cultivated potato accessions, while others exhibit 96% identity. Spls‐KPI‐B2 and Spls‐KPI‐B4 proteins contain unique substitutions of the most conserved residues usually involved to trypsin and chymotrypsin‐specific binding sites of Kunitz‐type protease inhibitor (KPI)‐B, respectively. To test the inhibition of trypsin and chymotrypsin by Spls‐KPI proteins, five of them were produced in E. coli purified using a Ni‐sepharose resin and ion‐exchange chromatography. All recombinant Spls‐KPI‐B inhibited trypsin; Ki values ranged from 84.8 (Spls‐KPI‐B4), 345.5 (Spls‐KPI‐B1), and 1310.6 nM (Spls‐KPI‐B2) to 3883.5 (Spls‐KPI‐B5) and 8370 nM (Spls‐KPI‐B3). In addition, Spls‐KPI‐B1 and Spls‐KPI‐B4 inhibited chymotrypsin. These data suggest that regardless of substitutions of key active‐center residues both Spls‐KPI‐B4 and Spls‐KPI‐B1 are functional trypsin‐chymotrypsin inhibitors.
Alternating penalty quadrilinear decomposition algorithm for an analysis of four‐way data arrays
Authors: Xia A‐Lin , Wu Hai‐Long , Li Shu‐Fang , Zhu Shao‐Hua , Hu Le‐Qian , Yu Ru‐Qin
Published: July 2007

A novel algorithm, alternating penalty quadrilinear decomposition (APQLD), is developed as an extension of alternating penalty trilinear decomposition (APTLD) for decomposition of quadrilinear data and applied to third‐order calibration. The proposed method as well as four‐way parallel factor analysis (PARAFAC) not only retains the second‐order advantages possessed in second‐order calibration but also holds additional advantage, for example with trilinear data from one sample, the intrinsic profiles in each order can be determined uniquely for each species in the sample. From simulations, it is observed that another advantage is that the introduction of fourth mode can relieve the serious problem of collinearity. It can be defined the ‘third‐order advantage’. It was shown a much higher convergence rate compared with four‐way PARAFAC. Moreover, it is generally insensitive to the overestimates of the component number chosen. This offers the advantage that in third‐order calibration one need not pay much attention to determining a proper component number for the model, and it is difficult for four‐way PARAFAC to avoid it. By treating simulated and one real excitation‐emission‐pH data sets, the results indicated that both APQLD and PARAFAC work well, but the performance of APQLD is better than that of PARAFAC in the prediction of concentration even if the component number chosen is the same as the actual number of underlying factors in the real system.

Published: July 2007

Different protozoa and metazoa populations develop in the activated sludge wastewater treatment processes and are highly dependent on the operating conditions. In the current work the protozoa and metazoa groups and species most frequent in wastewater treatment plants were studied, mainly the flagellate, sarcodine, and ciliate protozoa as well as the rotifer, gastrotrichia, and oligotrichia metazoa. The work is centered on the survey of the wastewater treatment plant conditions by protozoa and metazoa population using image analysis, discriminant analysis (DA), and neural networks (NNs) techniques, and its main objective was set on the evaluation of the importance of raw data pre‐processing techniques in the final results. The main pre‐processing techniques herein studied were the raw parameters reduction set by a joint cross‐correlation and decision trees (DTs) procedure and two data normalization techniques: logarithmic normalization and standard deviation normalization. Regarding the parameters reduction methodology, the use of a joint DTs and correlation analysis (CA) procedure resulted in 28 and 30% reductions in terms of the initial parameters set for the stalked and non‐stalked microorganisms, respectively. Consequently, the use of the reduced parameters set has proven to be a suitable starting point for both the DA and NNs methodologies, although for the DA an initial logarithmic normalization step is advisable. For the NNs analysis a standard deviation normalization procedure could be considered for the non‐stalked microorganisms regarding the operating parameters assessment.

Electronic Perturbation in a Molecular Nanowire of [IrCl5(NO)]− Units

The nitrosyl in [IrCl5(NO)]− is probably the most electrophilic known to date. This fact is reflected by its extremely high IR frequency in the solid state, electrochemical behavior, and remarkable reactivity in solution. PPh4[IrCl5(NO)] forms a crystal in which the [IrCl5(NO)]− anions are in a curious wire‐like linear arrangement, in which the distance between the NO moiety of one anion and the trans chloride of the upper one nearby is only 2.8 Å. For the same complex [IrCl5(NO)]− but with a different counterion, Na[IrCl5(NO)], the anions are stacked one over the other in a side‐by‐side arrangement. In this case the electronic distribution can be depicted as the closed‐shell electronic structure IrIIINO+, as expected for any d6 third‐row transition metal complex. However, in PPh4[IrCl5(NO)] an unprecedented electronic perturbation takes place, probably due to NO.–Cl− acceptor–donor interactions among a large number of [IrCl5(NO)]− units, favoring a different electronic distribution, namely the open‐shell electronic structure IrIVNO.. This conclusion is based on XANES experimental evidence, which demonstrates that the formal oxidation state for iridium in PPh4[IrCl5(NO)] is +4, as compared with +3 in K[IrCl5(NO)]. In agreement, solid‐state DFT calculations show that the ground state for [IrCl5(NO)]− in the PPh4+ salt comprises an open‐shell singlet with an electronic structure which encompasses half of the spin density mainly localized on a metal‐centered orbital, and the other half on an NO‐based orbital. The electronic perturbation could be seen as an electron promotion from a metal–chloride to a metal–NO orbital, due to the small HOMO–LUMO gap in PPh4[IrCl5(NO)]. This is probably induced by electrostatic interactions acting as a result of the closeness and wire‐like spatial arrangement of the Ir metal centers, imposed by lattice forces due to π–π stacking interactions among the phenyl rings in PPh4+. Experimental and theoretical data indicate that in PPh4[IrCl5(NO)] the IrNO moiety is partially bent and tilted.
Computational Study of the Phosphoryl Transfer Catalyzed by a Cyclin‐Dependent Kinase
Authors: De Vivo Marco , Cavalli Andrea , Carloni Paolo , Recanatini Maurizio
Published: July 2007

A cyclin‐dependent kinase, Cdk2, catalyzes the transfer of the γ‐phosphate from ATP to a threonine or serine residue of its polypeptide substrates. Here, we investigate aspects of the reaction mechanism of Cdk2 by gas‐phase density functional calculations, classical molecular dynamics, and Car–Parrinello QM/MM simulations. We focus on the role of the conserved Asp127 and on the nature of the phosphoryl transfer reaction mechanism catalyzed by Cdk2. Our findings suggest that Asp127 is active in its deprotonated form by assisting the formation of the near‐attack orientation of the substrate serine or threonine. Therefore, the residue does not act as a general base during the catalysis. The mechanism for the phosphoryl transfer is a single SN2‐like concerted step, which shows a phosphorane‐like transition state geometry. Although the resulting reaction mechanism is in agreement with a previous density functional study of the same catalytic reaction mechanism (Cavalli et al., Chem. Comm. 2003, 1308–1309), the reaction barrier is considerably lower when QM/MM calculations are performed, as in this study (≈42 kcal mol−1 QM vs. ≈24 kcal mol−1 QM/MM); this indicates that important roles for the catalysis are played by the protein environment and solvent waters. Because of the high amino acid sequence conservation among the whole family of cyclin‐dependent kinases (CDKs), these results could be general for the CDK family.
The Versatile Reactivity of cyclo‐(P5tBu4)− with Complexes of the Nickel Triad
Authors: Gómez‐Ruiz Santiago , Schisler Andrea , Lönnecke Peter , Hey‐Hawkins Evamarie
Published: July 2007

Na[cyclo‐(P5tBu4)] (1) reacts with [NiCl2(PEt3)2] and [PdCl2(PMe2Ph)2] with elimination of tBuCl and formation of the corresponding metal(0) cyclopentaphosphene complexes [Ni{cyclo‐(P5tBu3)}(PEt3)2] (2) and [Pd{cyclo‐(P5tBu3)}(PMe2Ph)2] (3). In contrast, complexes with the more labile triphenylphosphane ligand, such as [MCl2(PPh3)2] (M=Ni, Pd), react with 1 with formation of [NiCl{cyclo‐(P5tBu4)}(PPh3)] (4) and [Pd{cyclo‐(P5tBu4)}2] (5), respectively, in which the cyclo‐(P5tBu4) ligand is intact. In the case of palladium, the cyclopentaphosphene complex [Pd{cyclo‐(P5tBu3)}(PPh3)2] (6) in trace amounts is also formed. However, [Ni{cyclo‐(P5tBu4)}2] (7) is easily obtained by reaction of two equivalents of 1 and one equivalent of [NiCl2(bipy)] at room temperature. Complex 7 rearranges on heating in n‐hexane or toluene to the previously unknown [Ni{cyclo‐(P5tBu4)PtBu}{cyclo‐(P4tBu3)}] (8), which presumably is formed via the intermediate [Ni{cyclo‐(P5tBu4)}{cyclo‐(P4tBu3)PtBu}], which, after an unexpected and unprecedented phosphanediide migration, gives 8, but always as an inseparable mixture with 7. In the reaction of 1 with [PtCl2(PPh3)2], ring contraction and formation of [PtCl{cyclo‐(P4tBu3)PtBu}(PMe2Ph)] (9) is observed. Complexes 3–5 and 7–9 were characterised by 31P NMR spectroscopy, and X‐ray structures were obtained for 5–9.
Conformational Effects of Bay Substituents on Optical, Electrochemical and Dynamic Properties of Perylene Bisimides: Macrocyclic Derivatives as Effective Probes
Authors: Osswald Peter , Würthner Frank
Published: July 2007

A series of diagonally and laterally bridged regioisomeric macrocycles based on 1,6,7,12‐tetraaryloxy‐substituted perylene bisimides (APBIs) have been synthesized and characterized. The different orientations of the aryloxy residues, that is, horizontal or perpendicular to the perylene core, in the regioisomeric macrocycles have been elucidated by NMR spectroscopy, and the dynamic properties of the laterally bridged regioisomers have been investigated by temperature‐dependent NMR measurements. The influence of the different orientations of the aryloxy substituents on the electrochemical properties of APBIs is demonstrated by cyclic voltammetry, which reveals that a perpendicular orientation of the aryloxy residues relative to the perylene core leads to a substantial decrease of the LUMO energy level of the perylene bisimide electrophore. The optical properties of the regioisomeric macrocycles have been determined by UV/Vis and fluorescence spectroscopy. It has been shown that the diagonally bridged macrocycles exhibit optical properties that differ significantly from those of an open‐chain reference compound, whereas the optical properties of the laterally bridged isomers resemble those of the reference system. This demonstrates that unrestricted aryloxy substituents prefer the lateral conformation in solution. Solvent‐dependent fluorescent properties have been exemplified for one diagonally bridged derivative, suggesting a photoinduced electron transfer process as fluorescence quenching mechanism for APBIs. From these investigations, guidelines toward highly fluorescent APBI dyes in polar media could be derived.
