Dynamics for the focusing, energy-critical nonlinear Hartree equation
Authors: Miao Changxing , Wu Yifei , Xu Guixiang 
Published: October 2012

Abstract

By Li, Miao and Zhang (2009) and Miao, Xu and Zhao (2009),
the dynamics of the solutions for
the focusing energy-critical Hartree equation have been classified
when E(u
0) < E(W), where W is the ground state. In this paper, we
continue the study on the dynamics of the radial solutions with the
threshold energy under the assumption of the nondegeneracy of the
linearized operator near ground state. Our arguments closely follow
those of Duyckaerts and Merle (2008, 2009), Duyckaerts and Roudenko (2010)
and
Li and Zhang (2009, 2011). The new ingredient is that we show that the
positive solution of the nonlocal elliptic equation in
L
2d/(d-2)(ℝ
d
) is regular and unique by the moving plane
method in its global form, which plays an important role in the
spectral theory of the linearized operator and the dynamics behavior
of the threshold solution. Moreover, the nondegeneracy property of
the linearized operator can be shown in the Newtonian's potential
case (that is, d = 6).

Published: October 2012

Abstract
In cancer patients, appetite and immune status are significantly weakened. Two experimental fermented formulations without (group A, named as FSWW08) and with (group B, FSWW08) an extract from yam root were investigated against a placebo formulation with casein (group C) in a clinical study conducted in six cancer hospitals where cancer patients underwent radio or chemotherapy (patients undergoing radiation therapy n=78, patients undergoing chemotherapy n=184, total 262). IgG and IgA were increased by formulation A in patients despite receiving radio- or chemotherapy. Group A experienced statistically significant increases in lymphocyte transformation rates, whereas group B and group C did not. Formulations A and B either inhibited or lessened statistically significant decreases in white blood counts, whereas the placebo group experienced substantial decreases. Hemoglobin and platelet decreases were inhibited in group A, although not statistically significantly. Patients in group A received no blood transfusions, whereas many patients from the placebo group received blood transfusions. Appetite loss was reduced in group A from 57.9% to 13.3% and in group B from 70% to 35.8%. In the placebo group, an increase in appetite loss was detected under chemo and radiation therapy from 41.8% to 70.9%.

Published: October 2012

Abstract
We performed biochemical, histochemical and cell biological characterization of septins by focusing on SEPT1 in human skin tissues and a squamous cell carcinoma (SCC) cell line DJM-1. In immunoblotting, SEPT1, together with other septins, was detected in normal human epidermis, SCC and DJM-1. In immunohistochemical analyses, SEPT1 was detected diffusely in the cytoplasm of human epidermal cells and eccrine gland epithelial cells, and the protein level was increased in some skin tumors. In DJM-1 cells, SEPT1 together with other members of SEPT2-subgroup, SEPT4 and SEPT5, was enriched in lamellipodia and the localization was dependent on the cortical actin structure. SEPT1 distribution at lamellipodia was also observed in melanoma B16 cells. SEPT9, SEPT11 and SEPT14, in contrast, were localized along with microtubules in DJM-1 cells. In immunoprecipitation assays, SEPT1 and SEPT5 were found to form a complex in DJM-1 cells, whereas SEPT9, SEPT11 and SEPT14 formed a distinct complex with other septins including SEPT7, SEPT8 and SEPT10, in which SEPT5 was not included. When SEPT1 was silenced in DJM-1 cells, cell spreading was inhibited. These results suggest that SEPT1 may participate in cell-cell and/or cell-substrate interaction in DJM-1 and exert its function in a coordinated manner with other septins.
Cellular microcompartments constitute general suborganellar functional units in cells
Authors: Holthuis Joost C.M. , Ungermann Christian 
Published: October 2012

Abstract
All cells are compartmentalized to facilitate enzymatic reactions or cellular dynamics. In eukaryotic cells, organelles differ in their protein/lipid repertoire, luminal ion composition, pH, and redox status. In addition, organelles contain specialized subcompartments even within the same membrane or within its lumen. Moreover, the bacterial plasma membrane reveals a remarkable degree of organization, which is recapitulated in eukaryotic cells and often linked to cell signaling. Finally, protein-based compartments are also known in the bacterial and eukaryotic cytosol. As the organizing principle of such cellular subcompartments is likely similar, previous definitions like rafts, microdomains, and all kinds of ‘-somes’ fall short as a general denominator to describe such suborganellar structures. Within this review, we will introduce the term cellular microcompartment as a general suborganellar functional unit and discuss its relevance to understand subcellular organization and function.
Oxidation and Evaporation Behaviors of Cr, Cu and As During Incineration of Wood Treated by Chromated Copper Arsenate Preservative
Authors: Matsumoto Takahiko , Matsuura Hiroyuki , Tsukihashi Fumitaka 
Published: October 2012

AbstractWoody materials treated by chromated copper arsenate (CCA) preservative containing copper, chromium and arsenic had been widely used, and thus it is anticipated that a lot of wood waste treated by CCA will be generated as the industrial waste in the future. The environmental pollution by the released heavy metals becomes a serious problem when the wood treated by CCA was incinerated inadequately. There needs the investigation for the behaviors of heavy metals during incineration of wood treated by CCA.The wood sample treated by CCA was incinerated at temperature range between 873 and 1673 K with the oxygen partial pressure between 0.21 and 0.40 atm completely. The proportion of evaporated arsenic increased with increasing temperature and most of arsenic evaporated at about 1600 K. It was suggested that arsenic evaporated as As2O3 or As4O6 during the incineration. On the other hand, most of copper and chromium remained in the bottom ash. The evaporation behaviors of arsenic largely depended on the incineration temperature, while the effects of the oxygen partial pressure of inlet gas and gas flow rate on those were small. Powder XRD analysis of bottom ash revealed that copper and chromium existed as CuCr2O4 and CuCrO2. CuCr2O4 was mainly contained in the bottom ash incinerated at temperature below 1273 K, whereas the ratio of CuCrO2 increased with increasing incineration temperature above 1273 K. Therefore, most of copper and chromium were bivalent and trivalent, respectively, in the bottom ash, and some copper was converted to a monovalent over 1273 K. Almost all arsenic was contained as pentavalent Cu3(AsO4)2, and arsenic was not identified in bottom ash incinerated at temperature above 1273 K.

Published: October 2012

Abstract

Background: The aim of this study was to compare the effect of adrenaline on blood glucose concentration in patients with diabetes undergoing tooth extraction under local anesthesia and also to find out whether blood glucose concentration differs if local anesthetics are injected in clinical doses with and without adrenaline.

Methods: Patients included had a tooth in need of extraction, were in the 25–55 years age group, had a random blood sugar level ≤140 mg/dL and were on oral antidiabetic drugs. The 25 patients in Group A were injected with 2 mL of lignocaine hydrochloride without adrenaline (xylocaine 2%) and the other 25 patients (Group B) were injected with 2 mL lignocaine hydrochloride along with adrenaline 1:80,000. Serial blood glucose estimations were made at regular intervals of 10 min before local anesthesia and subsequently 10 and 20 min after local anesthesia.

Results: A statistically significant difference of the mean blood glucose concentration was noticed at three different time intervals between the two groups.

Conclusions: Dental local anesthetic solutions containing adrenaline may safely be used in patients with diabetes who had taken their hypoglycemic medications preoperatively.

Published: October 2012

Abstract

Background: Yoyo Bitters is an indigenous polyherbal preparation widely consumed in Nigeria. In spite of its wide consumption there is little scientific data on the safety/toxicity profile of Yoyo Bitters. This study determined the biochemical effect of daily administration of Yoyo Bitters on rat serum, kidney and liver.

Methods: A total of 20 Wistar rats, of average weight between 175 and 200 g, were randomly distributed into four groups of five rats each. Group A served as controls and received distilled water. Groups B, C and D were given Yoyo Bitters at various dosages. Treatments were orally administered for 28 days.

Results: Yoyo Bitters caused lipid peroxidation as reflected in serum and liver malondialdehyde (MDA) levels which were significantly (p<0.05) elevated in a dose-dependent manner. In groups treated with 1206.5 mg and 804.3 mg/kg dosages of Yoyo Bitters, serum superoxide dismutase (SOD) levels were also significantly (p<0.05) increased. By contrast, Yoyo Bitters caused a dose-dependent reduction in reduced glutathione (GSH) levels. It is not clear if free radicals or lipid peroxidation caused changes in SOD and GSH levels. However, Yoyo Bitters may have enhanced free radical generation and ensuing lipid peroxidation leading to increased SOD and subsequent dose-dependent depletion of GSH levels.

Conclusions: In light of this, caution and adherence to dosage prescription is strongly advised. This study is a contribution to scientific knowledge on the safety/toxicity profile of Yoyo Bitters among the growing list of Nigerian herbal remedies.

Phonetic explanations for the infrequency of voiced sibilant affricates across languages
Authors: Żygis Marzena , Fuchs Susanne , Koenig Laura L. 
Published: October 2012

AbstractThis paper shows that several typologically unrelated languages share the tendency for voiced sibilant affricates to be infrequent or missing altogether. Phonological processes examined in the paper illustrate that (1) voiceless stops undergo affrication more readily than voiced ones, and (2) voiced affricates deaffricate more commonly than voiceless ones, thereby contributing to the asymmetry in frequency between voiced vs. voiceless affricates.Phonetic properties of the sounds may explain these patterns. Affricates in general require complex control over supralaryngeal apertures, and they appear to have long durations in many languages. Long duration and complete oral closure at the beginning of affricates contribute to a buildup of intraoral pressure which impedes phonation. An aerodynamic experiment of obstruents, including affricates, was carried out for Polish and German, languages which differ in their realization of the stop voicing contrast (viz., voicing vs. aspiration). Voiced affricates in Polish had significantly longer voicing than in German; in medial position, they also had shorter durations and lower peak pressure values. We suggest that languages having voiced affricates in their phoneme inventory may tend to limit duration and intraoral pressure buildup in these sounds to allow vocal-fold vibration to continue.

Published: October 2012

AbstractThe objective of this study was to investigate the effect of power on low-level lasers used in photodynamic therapy (PDT) to treat chronic plaque psoriasis in a group of Sudanese patients.Twenty-four patients with chronic plaque psoriasis were randomly selected to enter this study from a total of 100 patients who attended the Khartoum Dermatology Teaching Hospital between 2010 and 2011. The lasers used for PDT were three continuous wave diode lasers in the red portion of the electromagnetic spectrum (671–675 nm) with output powers of 16, 50 and 100 mW to activate the chemical photosensitizer (LevulanThis study showed that 62% of the patients treated with 100 mW achieved complete clearance compared with 25% for those treated with 50 mW and 0% for those treated with 16 mW.The results showed that increasing the power of low-level laser in PDT increased the clearance of plaque psoriasis. PDT can be used as an alternative method for treatment of psoriasis.
Hydrophobicity and Biofilm Growth ofE-coliRP437, MG1655 and B/r
Authors: Zhao Li Hong , Sen Pabitra N. 
Published: October 2012

ABSTRACTTwo strains ofE-ColiK-12, viz, RP437, MG1655 and B/r (E. coliB derivative, not a K-12 strain) were grown on various surfaces to study bacterial adhesion and subsequent biofilm formation. We observed biofilm and large colonies on cover slides, beads made of soda lime or borosilicate glasses, on plasma treated PDMS (Polydimethylsiloxane), on Tissue Culture (TC) polystyrene, and observed some clusters on plasma treated ZnTi cover slide; but no evidence of biofilm on untreated-PDMS and ZnTi glass cover slides. From contact angle measurements, we conclude that the hydrophobic nature of untreated PDMS prevent bacterial adhesion for these three strains.
Students' Experiences with Web-Based Alcohol Prevention: A Qualitative Evaluation of Alcoholedu
Authors: Nygaard Peter , Paschall Mallie J. 
Published: October 2012

Aim: To provide more in-depth information about students' experiences with AlcoholEdu and in particular to assess if students perceive that the course gives them tools to better control their drinking-related behavior. Methods: Focus group interviews with freshmen at three California universities. Findings: 1) The course provides so much information that everyone can find some of it relevant; 2) participants prefer information presented in ways they can identify with; 3) participants report problems with surveys in the program pointing to redundancy and length; and 4) participants did not expect the course to impact their behavior relating to alcohol. Conclusion: AlcoholEdu provides valuable information for freshmen in college about how to avoid problems with alcohol. However, the course could have much more impact if closer to college reality.
Long-term evaluation of the molar movements following Pendulum and fixed appliances
Authors: Caprioglio Alberto , Fontana Mattia , Longoni Elena , Cozzani Mauro 
Published: October 2012

ABSTRACT

Objective:
To describe the molar movements and skeletal changes associated with Pendulum-fixed appliance treatment and the long-term postretention period.

Subjects and Methods:
The treatment sample consisted of 76 Class II patients, 35 males and 41 females. Lateral cephalograms were obtained at the start of treatment (T1); the end of distalization (T2); the end of orthodontic fixed appliance therapy (T3); and long-term observation (7 years 2 months later; T4). Mean age was 12 years 11 months at T1, 13 years 8 months at T2, 15 years 4 months at T3, and 22 years 5 months at T4. The average amount of Class II molar relationship was 3.1 mm, with a mean overjet of 5.9 mm at the beginning of treatment. A paired t-test was used to identify significant between-group differences between T2–T4 and T3–T4.

Results:
Distal molar movement was obtained during the distalization phase (T2), and more than half of the distalizing effect was maintained at the end of maxillary growth (T4). Most of the relapse occurred during fixed appliance therapy (T3), whereas no significant change was detected in the postretention period (T4). The molar relationship did not show any significant difference between T2 and T4. The vertical facial dimension increased during the distalization phase (T2) and fixed appliance therapy (T3) but returned to the initial values during the postretention period (T4).

Conclusions:
The Pendulum appliance induces significant dentoalveolar effects, which can be partially maintained during the long-term period. The Class I molar relationship does not change during completion of individual growth. Increase in vertical facial dimension represents a temporary effect.

Published: October 2012

ABSTRACTObjectives:To compare (1) speech performance based on an auditive analysis and sonagraphy and (2) levels of oral impairment between fixed lingual and labial orthodontic appliances.Materials and Methods:Thirty-four patients with Class I division 1 malocclusion and moderate crowding of upper teeth were distributed randomly into two groups. Seventeen patients in group A (mean age: 20.6 years; standard deviation [SD]: 2.9 years) were treated with fixed lingual appliances (Stealth®, AO, Sheboygan, Wisc), whereas 17 patients in group B (mean age: 21.8 years; SD: 3.3 years) were treated with conventional fixed labial appliances. Speech performance was tested using spectrographic analysis of fricative /s/ sound before, immediately after (T1), 1 month after, and 3 months after bracket placement. The levels of oral impairment were assessed using standardized questionnaires.Results:A significant deterioration in articulation was recorded at all assessment times in group A but only at T1 in group B. Significant intergroup differences were recorded at all assessment times (P &lt; .001). Speech difficulties were significantly higher in the lingual brackets group after 1 month of bracket placement (P &lt; .001). Soft tissue irritation and chewing difficulty were significantly higher in the lingual appliance group after 24 hours of bracket placement (P &lt; .001).Conclusions:The lingual appliance is more problematic than the labial one in terms of speech articulation. Although patients with both appliances suffered from different degrees of oral impairment, patients with lingual appliances had more untoward effects, particularly during the first month of treatment.
On the irreducibility of Hilbert scheme of surfaces of minimal degree
Authors: Bogomolov Fedor , Kulikov Viktor 
Published: October 2012

Abstract
The article contains a new proof that the Hilbert scheme of irreducible surfaces of degree m in ℙm+1 is irreducible except m = 4. In the case m = 4 the Hilbert scheme consists of two irreducible components explicitly described in the article. The main idea of our approach is to use the proof of Chisini conjecture [Kulikov Vik.S., On Chisini’s conjecture II, Izv. Math., 2008, 72(5), 901–913 (in Russian)] for coverings of projective plane branched in a special class of rational curves.
New results from fluctuation analysis in NA49 at the CERN SPS
Authors: Maćkowiak-Pawłowska Maja 
Published: October 2012

Abstract
The exploration of the phase diagram of strongly interacting matter, particularly the study of the phase transition from hadronic to partonic matter and the search for a hypothetical critical endpoint of the first order transition line, is one of the most challenging tasks in present heavy ion physics.
New results on chemical (particle ratio), transverse momentum, multiplicity and azimuthal angle fluctuations are presented. We also discuss their connection to the onset of deconfinement and to the critical endpoint.
Finite size scaling on the phase diagram of QCD
Authors: Gupta Sourendu 
Published: October 2012

Abstract
In the last few years there has been remarkable progress in the comparison of experimental data on the shape of event-by-event distributions of conserved quantities and lattice thermodynamic predictions based on the grand canonical ensemble. In this talk we discuss how the QCD crossover temperature and the freezeout curve are extracted from the analysis of fluctuations. We report that one can also go further and locate the QCD critical point at µ }~ 2T
c. We also list the systematics which must be brought under control in future.
Higher-order ratios of baryon number cumulants
Authors: Schaefer Bernd-Jochen , Wagner Mathias 
Published: October 2012

Abstract
The relevance of higher order cumulants of net baryon number fluctuations for the analysis of freeze-out and critical conditions in heavy-ion collisions at LHC and RHIC is addressed. The sign structure of the higher order cumulants in the vicinity of the chiral crossover temperature might be a sensitive probe and may allow to elucidate their relation to the QCD phase transition. We calculate ratios of generalized quarknumber susceptibilities to high orders in three flavor QCD-like models and investigate their sign structure close to the chiral crossover line.
Understanding of radial and elliptic expansion with quark number scaling and blast wave model in 200 GeV Au+Au at RHIC-PHENIX
Authors: Ikeda Yoshimasa 
Published: October 2012

Abstract
Measurement of azimuthal anisotropy is one of the most important study because of its relation to the initial stage. Especially, the elliptical anisotropy which is measured as the second coefficient of Fourier expansion of particle azimuthal distribution is believed to carry the information about the initial geometrical anisotropy. It seems the identified hadron v
2 depends on the number of quark contents of the hadron. The experimental result of quark number scaling of v
2 suggests quark level collectivity in the hot dense matter and quark coalescence mechanism to form hadron from quark matter via quark-gluon phase transition. The measured v
2 and p
T spectra are analyzed with various assumptions based on the blast wave model in order to understand the freeze-out temperature and collective flow after the system expansion.
Directed flow from global symmetry and initial state Fluctuations

Published: October 2012

Abstract
Collective flow is studied in a 3+1D fluid dynamical model with globally symmetric, peripheral initial conditions, taking into account the shear flow. At $\sqrt {s_{NN} } $ = 2.76 TeV in semi-peripheral Pb+Pb collisions this leads to rotation, while at more peripheral collisions with high resolution and low numerical viscosity, the initial development of a Kelvin-Helmholz instability is observed. This effect provides a precision tool for studying the viscosity of Quark-Gluon Plasma.
