Published: January 2012

ABSTRACTObjectives:The aim of the present study was to assess long‐term survival and success rates of implants in the edentulous maxilla restored with an implant‐supported fixed prosthesis.Materials and Methods:Seventeen edentulous patients received six to eight implants and implant‐supported fixed prostheses by one surgeon. Yearly recalls were conducted by two examiners over a period of 11 years. Survival and success rates (biological complications) were determined; marginal bone loss was examined radiographically. Furthermore, microbiological tests as well as test for interleukin‐1 composite genotype were assessed and potential risk factors were evaluated.Results:After a mean time of 11.26 years, 15 patients of 17 could be reexamined. Out of 94 implants, three were lost in one patient. Mean marginal bone loss reached 0.88 mm, two patients (at seven implants) showed bone loss of ≥3.2 mm. Survival rate of implants reached 96.8%. Success rates on implant level hit 92.6% according to the criteria of Albrektsson and colleagues and 83.0% in accordance with Karoussis and colleagues. One prosthesis had to be renewed.Conclusion:Within the limitation of this study, restoration of the edentulous maxilla with an implant‐supported fixed prosthesis represents an effective tool for rehabilitation over a period of 11 years.

Published: January 2012

ABSTRACTPurpose: The relationship of conventional multi‐slice computed tomography (CT)‐ and cone beam CT (CBCT)‐based gray density values and the primary stability parameters of implants that were placed by stereolithographic surgical guides were analyzed in this study.Materials and Methods: Eighteen edentulous jaws were randomly scanned by a CT (CT group) or a CBCT scanner (CBCT group) and radiographic gray density was measured from the planned implants. A total of 108 implants were placed, and primary stability parameters were measured by insertion torque value (ITV) and resonance frequency analysis (RFA). Radiographic and subjective bone quality classification (BQC) was also classified. Results were analyzed by correlation tests and multiple regressions (p < .05).Results: CBCT‐based gray density values (765 ± 97.32 voxel value) outside the implants were significantly higher than those of CT‐based values (668.4 ± 110 Hounsfield unit, p < .001). Significant relations were found among the gray density values outside the implants, ITV (adjusted r2 = 0.6142, p = .001 and adjusted r2 = 0.5166, p = .0021), and RFA (adjusted r2 = 0.5642, p = .0017 and adjusted r2 = 0.5423, p = .0031 for CT and CBCT groups, respectively). Data from radiographic and subjective BQC were also in agreement.Conclusions: Similar to the gray density values of CT, that of CBCT could also be predictive for the subjective BQC and primary implant stability. Results should be confirmed on different CBCT scanners.

Cold shock proteins (Csps) include both cold‐induced and non‐cold‐induced proteins, contrary to their name. Cold‐induced Csps are well studied; they function in cold acclimation by controlling transcription and translation. Some Csps have been reported to contribute to other cellular processes. However, the functions of non‐cold‐induced Csps under optimal growth conditions remain unknown. To elucidate these functions, we used transcriptome and proteome analyses as comprehensive approaches and have compared the outputs of wild‐type and non‐cold‐induced Csp‐deletion mutant cells. As a model organism, we selected Thermus thermophilus HB8 because it has only two csp genes (ttcsp1 and ttcsp2); ttCsp1 is the only non‐cold‐induced Csp. Surprisingly, the amount of transcripts and proteins upon deletion of the ttcsp1 gene was quite different. DNA microarray analysis revealed that the deletion of ttcsp1 did not affect the amount of transcripts, although the ttcsp1 gene was constantly expressed in the wild‐type cell. Nonetheless, proteomic analysis revealed that the expression levels of many proteins were significantly altered when ttcsp1 was deleted. These results suggest that ttCsp1 functions in translation independent of transcription. Furthermore, ttCsp1 is involved in both the stimulation and inhibition of translation of specific proteins. Here, we have determined the crystal structure of ttCsp1 at 1.65 Å. This is the first report to present the structure of a non‐cold‐inducible cold shock protein. We also report the nucleotide binding affinity of ttCsp1. Finally, we discuss the functions of non‐cold‐induced Csps and propose how they modulate the levels of specific proteins to suit the prevailing environmental conditions.DatabaseStructural data are available in the Protein Data Bank databases under the accession number 3A0J
Review article: Part two: Goal‐directed resuscitation – Which goals? Perfusion targets
Authors: Holley Anthony , Lukin William , Paratz Jennifer , Hawkins Tracey , Boots Robert , Lipman Jeffrey 
Published: January 2012

AbstractHaemodynamic targets, such as cardiac output, mean arterial blood pressure and central venous oxygen saturations, remain crude predictors of tissue perfusion and oxygen supply at a cellular level. Shocked patients may appear adequately resuscitated based on normalization of global vital signs, yet they are still experiencing occult hypoperfusion. If targeted resuscitation is employed, appropriate use of end‐points is critical. In this review, we consider the value of directing resuscitation at the microcirculation or cellular level. Current technologies available include sublingual capnometry, video microscopy of the microcirculation and near‐infrared spectroscopy providing a measure of tissue oxygenation, whereas base deficit and lactate potentially provide a surrogate measure of the adequacy of global perfusion. The methodology and evidence for these technologies guiding resuscitation are considered in this narrative review.

Part 2: Goal Directed Resuscitation – Which Goals? Perfusion Targets will follow in the next issue.AbstractThe use of appropriate resuscitation targets or end‐points may facilitate early detection and appropriate management of shock. There is a fine balance between oxygen delivery and consumption, and when this is perturbed, an oxygen debt is generated. In this narrative review, we explore the value of global haemodynamic resuscitation end‐points, including pulse rate, blood pressure, central venous pressure and mixed/central venous oxygen saturations. The evidence supporting the reliability of these parameters as end‐points for guiding resuscitation and their potential limitations are evaluated.
Separating Test Artifacts from Material Behavior in the Oxidation Studies of HfB2–SiC at 2000°C and Above
Authors: Carney Carmen M. , Parthasarathy Triplicane A. , Cinibulk Michael K. 
Published: January 2012

Oxidation characteristics of HfB2‐15 vol% SiC prepared by field‐assisted sintering was examined at 2000°C by heating it in a zirconia‐resistance furnace and by direct electrical resistance heating of the sample. Limitations of the material and the direct electrical resistance heating apparatus were explored by heating samples multiple times and to temperatures in excess of 2300°C. Oxide scales that developed at 2000°C from both methods were similar in that they consisted of a SiO2/HfO2 outer layer, a porous HfO2 layer, and a HfB2 layer depleted of SiC. But they differed in scale thicknesses, impurities present, scale morphology/complexity. Possible test artifacts are discussed.

Authors: Masuda, Yoshitake , Ohji Tatsuki , Kato Kazumi 
Published: January 2012

Characteristic tin oxide films were formed on transparent conductive substrates in aqueous solutions. Surface of the films consisted of ellipse‐shaped particles. Particle size in longer or shorter direction was about 300–400 or 200 nm, respectively. In contrast, middle and bottom area of the films were dense structures. Thickness was about 1150 nm. The film was single phase SnO2 with a‐axis orientation. The films had chemical ratio of O/Sn = 1.20–1.37 and F/Sn = 0.088–0.124, suggesting fluorine doping. Facile synthesis of tin oxide particulate films had advantages in ordinary temperature synthesis, water solvent process, and low‐environmental load.

Anode‐supported microtubular solid oxide fuel cells (SOFCs) based on Ce0.8Sm0.2O2‐δ (SDC) electrolytes were prepared using phase inversion and vacuum‐assisted coating techniques. With La0.6Sr0.4Co0.2Fe0.8O3‐δ‐Ce0.8Sm0.2O2‐δ (LSCF‐SDC) as a cathode, the maximum power densities of the cell reached 38, 104, and 168 mW/cm2 at 500°C, 550°C, and 600°C, respectively; and the corresponding open‐circuit voltages (OCVs) were 0.74, 0.73, and 0.71 V. Furthermore, the OCVs could be significantly improved by way of brush painting a BaZr0.1Ce0.8Y0.1O3‐δ‐Ce0.8Sm0.2O2‐δ (BZCY‐SDC) layer on the SDC electrolyte membrane, achieving 0.81, 0.80, and 0.76 V at 500°C, 550°C, and 600°C, respectively.
Emergent Impacts of Ant and Spider Interactions: Herbivory Reduction in a Tropical Savanna Tree
Authors: Nahas Larissa , Gonzaga Marcelo O. , Del‐Claro Kleber 
Published: January 2012

AbstractMultiple predators often have effects on their common prey populations that cannot be predicted by summing the effects of each predator at a time. When predators forage on the same vegetation substrate, intraguild interactions might cause emergent outcomes for the plants on which the predators co‐occur. We experimentally evaluated the effects of spiders and ants on herbivory and reproduction in the extrafloral nectary‐bearing tree Qualea multiflora (Vochysiaceae). Plants were divided in four experimental groups, depending on the presence or absence of ants and spiders. We compared the effects of each treatment on richness and abundance of chewing and sucking herbivores and on herbivory (leaf area loss). We also evaluated the impact of predators on the production of buds, fruits and seeds, and weight of the fruits. The presence of ants reduced the abundance and richness of spiders, but spiders did not affect the abundance and richness of ants. Only the removal of ants resulted in a significant increase in the abundance of herbivores and herbivore richness. Herbivory, however, was also affected by spiders. In addition, we found a significant interaction effect of ants and spiders on herbivory, indicating an emergent multiple predator effect. Neither ants nor spiders had an impact on the number of buds produced, number of fruits per bud, and seeds per fruits or fruit weight. This study highlights the importance of evaluating the effect of the predator fauna as a whole and not only one specific group on herbivory.

AbstractA nationwide statistical survey of 4196 dialysis facilities was conducted at the end of 2009, and 4133 facilities (98.5%) responded. The number of patients undergoing dialysis at the end of 2009 was determined to be 290 661, an increase of 7240 patients (2.6%) compared with that of 2008. The number of dialysis patients per million at the end of 2009 was 2279.5. The crude death rate of dialysis patients from the end of 2008 to the end of 2009 was 9.6%. The mean age of the new patients introduced into dialysis was 67.3 years old and the mean age of the entire dialysis patient population was 65.8 years old. Primary diseases such as diabetic nephropathy and chronic glomerulonephritis for new dialysis patients, showed a percentage of 44.5% and 21.9%, respectively. Based on the facilities surveyed, 84.2% of the facilities that responded to the questionnaire satisfied the microbiological quality standard for dialysis fluids for the Japanese Society for Dialysis Therapy (JSDT), with an endotoxin concentration of less than 0.05 EU/mL in the dialysis fluid. Similarly, 98.2% of the facilities surveyed satisfied another standard of the society of a bacterial count of less than 100 cfu/mL in the dialysis fluid. The facility survey indicated that the number of patients who were treated by blood purification by both peritoneal dialysis and extracorporeal circulation, such as hemodialysis, was 1720. Among the total number of patients, 24.8% were satisfied with the management target recommended in the treatment guidelines for secondary hyperparathyroidism. These standards are set by the JSDT, based on the three parameters, i.e. serum calcium concentration, serum phosphorus concentration, and serum intact parathyroid hormone concentration. According to the questionnaire, 9.8% of the patients were considered to have a complication of dementia.

Published: January 2012

Abstract:  In the present study, Aspergillus oryzae‐inoculated koji inhibited lipid oxidation in fermented fish paste rich in polyunsaturated fatty acids following a long fermentation period. The fermentation of koji by A. oryzae liberated several bioactive phenolic compounds, including kojic acid and ferulic acid, which were the most abundant. A linear correlation between several phenolic compounds and their bioactive properties, including their radical‐scavenging activity, reducing power, metal‐chelating activity, and ability to inhibit linoleic acid oxidation was observed. This suggested an important role of koji phenolics in the oxidative stability of fermented fish paste. The activities of different carbohydrate‐cleaving enzymes, including α‐amylase, cellulase, and β‐glucosidase, were positively correlated with the liberation of several phenolic compounds through koji fermentation. Thus, the application of koji offers a novel strategy to enhance the oxidative stability of newly developed fermented fish miso.Practical Application:  Application of traditional Japanese koji fermentation technique to develop an aroma enriched fish meat bases seasoning has been established. Aspergillus oryzae‐inoculated koji releases several carbohydrate‐cleaving enzymes, including α‐amylase, cellulose, and β‐glucosidase, which led to the liberation of several phenolic compounds during fermentation. Improvement of oxidative stability of the fermented fish meat paste by koji phenolics suggests a useful strategy to uplift the value of different trash fish meat‐based seasoning through proper utilization of the present technique.
Uptake of Divalent Ions (Mn+2 and Ca+2) by Heat‐Set Whey Protein Gels
Authors: Oztop Mecit H. , McCarthy Kathryn L. , McCarthy Michael J. , Rosenberg Moshe 
Published: January 2012

Abstract:  Divalent salts are used commonly for gelation of polymer molecules. Calcium, Ca+2, is one of the most common divalent ions that is used in whey protein gels. Manganese, Mn+2, is also divalent, but paramagnetic, enhancing relaxation decay rates in magnetic resonance imaging (MRI) and can be used as a probe to understand the behavior of Ca+2 in whey protein gels. The objective of this study was to investigate the diffusion of Ca+2 and Mn+2 ions in heat‐set whey protein gels by using MRI and nuclear magnetic resonance (NMR) relaxometry. Whey protein gels were immersed in solutions containing MnCl2 and CaCl2 at neutral pH. Images obtained with gels immersed in MnCl2 solution revealed a relaxation sink region in the gel's surface and the thickness of the region increased with time. These “no signal” regions in the MR images were attributed to uptake of Mn+2 by the gel. Results obtained with CaCl2 solution indicated that since Ca+2 did not have the paramagnetic effect, the regions where Ca+2 diffused into the gel exhibited a slight decrease in signal intensity. The relaxation spectrums exhibited 3 populations of protons, for gels immersed in MnCl2 solution, and 2 populations for gels in CaCl2 solution. No significant change in T2 distributions was observed for the gels immersed in CaCl2 solution. The results demonstrated that MRI and NMR relaxometry can be used to understand the diffusion of ions into the whey protein gel, which is useful for designing gels of different physical properties for controlled release applications.Practical Application:  Design of food systems for delivery of bioactive compounds requires knowledge of diffusion rates and structure. Utilizing magnetic resonance imaging the diffusion rates of ions can be measured. Relaxation spectra could yield information concerning molecular interactions.
Structure and Dynamics of the Excited States of 1,3‐Diarylisobenzofurans: An Experimental and Theoretical Study

Published: January 2012

AbstractThe emission properties of a series of substituted 1,3‐diarylisobenzofurans have been studied. Most compounds exhibit very intense emission in the nanosecond timescale at room temperature as well as at 77 K. The room temperature emission is attributed to the deactivation of a twisted intramolecular charge transfer excited state, based on its energy, shape and solvent dependence. The experimental results are strongly supported by a theoretical study on one representative compound. The DFT/TD‐DFT calculations demonstrate that the initial excited state relaxes toward a twisted structure.
Whig Ballads and the Past Passive Jacobite
Authors: HAROL CORRINNE 
Published: January 2012

AbstractThis essay analyses the representation of Jacobitism in ballads about the Hanoverian succession crisis. Focusing on three aspects of Jacobite culture – passive obedience, typological history and the representation of the Stuart heir – it argues that Jacobites and ballads were mutually constructed as nostalgic. The essay thus explores the production of Jacobitism as nostalgic, and the implications of that production, arguing that this formulation was contemporaneous with Jacobitism, that it served both sides and that it contributed to Jacobitism as a modern, rather than an archaic, political identity.
English‐Language Newspapers in Revolutionary France
Authors: MACDONALD SIMON 
Published: January 2012

AbstractThis article examines a series of English‐language newspaper ventures produced in revolutionary France and largely aimed at export to Britain. These enterprises, chief among which was the Paris Mercury (1792), sought to profit from heightened British interest in French events by dispatching ready‐printed newspapers directly from Paris, thus achieving news priority over the domestic British press. New French press freedoms also enabled claims to be made about the superior editorial qualities of such extraterritorial newspapers. This article reconstructs these newspapers' publication history, reviews their contents, discusses their commercial and political rationale and their precursors, and offers explanations for their failure.
Spontaneous cluster activity in the inferior olivary nucleus in brainstem slices from postnatal mice
Authors: Rekling Jens C. , Jensen Kristian H. R. , Jahnsen Henrik 
Published: January 2012

Key points
The cerebellum is organized in modules, where groups of neurons in the inferior olivary nucleus (IO) are connected to elongated bands of Purkinje neurons in the cerebellar cortex; it is still largely unknown what the specific function of these modules is, and how they are formed.
Here we show that IO neurons spontaneously generate clusters of co‐active neurons in in vitro brain slice preparations from newborn mice, in an age window ranging from birth to two weeks old.
Intracellular recordings revealed that electrical coupling between neighbouring IO neurons may contribute to the synchronization.
The dorsomedial cell column, which is a subregion in the IO involved in the control of balance and posture, showed a high frequency of regular repeating clusters compared to the rest of the IO, suggesting that this system may be on a fast developmental track.
These results increase our understanding of how the circuitry of the cerebellar system develops in the early postnatal period, where animals acquire the ability to produce finely controlled motor acts.
Differential expression and function of nicotinic acetylcholine receptors in the urinary bladder epithelium of the rat
Authors: Beckel Jonathan M. , Birder Lori A. 
Published: January 2012

Key points
It has been previously shown that stimulation of urothelial nicotinic acetylcholine receptors (nAChRs) can alter reflex bladder activity in the rat; the current study examines this further.
Stimulation of rat urothelial cells with an α7 nAChR agonist increases intracellular calcium through internal stores and decreases basal ATP release.
Stimulation with an α3* nAChR agonist increases intracellular calcium through extracellular influx and increases basal ATP release.
Infusion of an α3* agonist into the bladder lumen of the rat increases reflex bladder activity, which is blocked by intra‐arterial administration of a purinergic antagonist.
The cellular effects of α3* stimulation are blocked when the cells are pretreated with an α7 agonist, suggesting cross‐talk between the receptors: this cross‐talk may be mediated through protein kinase A or protein kinase C.
