A Green and Novel Method of Synthesizing 2,2′‐Arylmethylene Bis(3‐hydroxy‐5,5‐dimethylcyclohex‐2‐enone) Catalyzed by L‐Histidine in Ionic Liquid
Authors: Zhang Yan , Shang Zhicai
Published: August 2010

An efficient and green approach to the synthesis of 2,2′‐arylmethylene bis(3‐hydroxy‐5,5‐dimethylcyclohex‐2‐enone) using L‐histidine as the catalyst is described. In addition, room temperature ionic liquid 1‐butyl‐3‐methylimidazonium tetrafluoroborate [bmim]BF4 was used as green recyclable alternatives to volatile organic solvents for this condensation reaction. This green catalytic system can be recycled several times with no decreases in yields and reaction rates.
Considering Dependencies Amongst Genes Helps to Adjust the Significance Rank of DEGs
Authors: Liu Qi , Ding Guohui , Huang Tao , Tan Yejun , Dai Hongyue , Xie Lu , Li Yixue
Published: August 2010

Lists of differentially expressed genes (DEGs) detected often show low reproducibility even in technique replicate experiments. The reproducibility is even lower for those real cancer data with large biological variations and limited number of samples. Since existing methods for identifying differentially expressed genes treat each gene separately, they cannot circumvent the problem of low reproducibility. Considering correlation structures of genes may help to mitigate the effect of errors on individual gene estimates and thus get more reliable lists of DEGs. We borrowed information from large amount of existing microarray data to define the expression dependencies amongst genes. We use this prior knowledge of dependencies amongst genes to adjust the significance rank of DEGs. We applied our method and four popular ranking algorithms including mean fold change (FC), SAM, t‐statistic and Wilcoxon rank sum‐test on two cancer microarray datasets. Our method achieved higher reproducibility than other methods across a range of sample sizes. Furthermore, our method obtained higher accuracy than other methods, especially when the sample size is small. The results demonstrate that considering the dependencies amongst genes helps to adjust the significance rank of genes and find those truly differentially expressed genes.
Serial histologic investigation of squamous epithelial dysplasia associated with carcinoma of the esophagus
Authors: Nagamatsu Masaaki , Mori Masaki , Kuwano Hiroyuki , Sugimachi Keizo , Akiyoshi Tsuyoshi
Published: August 2010

Esophageal dysplasia and carcinoma were reviewed in the surgical specimens obtained from 37 patients with squamous cell carcinoma and 4 with adenocarcinoma; special attention was paid to the continuity of both lesions. Two hundred forty dysplasias and 113 carcinomas in situ (CIS) were recognized in the squamous cell carcinoma cases and 2 dysplasias and no CIS in the adenocarcinoma cases. The CIS often was accompanied continuously by severe dysplasia rather than mild or moderate dysplasia, suggesting some relationship between the CIS and the severity of dysplasia. However, many dysplastic lesions were located separately from the carcinoma. The frequency of appearance of the dysplasia near the CIS was low (11%), demonstrating a negative dysplasia‐CIS sequence in many of the esophageal cancers. Lymphocytic infiltration was investigated further beneath the dysplasia or CIS. The degree of lymphocytic infiltration with lymphoid follicles correlated with the severity of dysplasia and was the highest in CIS.
Low‐dose rate telecobalt therapy as a boost against esophageal carcinomas
Authors: Yamada Shogo , Takai Yoshihiro , Nemoto Kenji , Ogawa Yoshihiro , Kakuto Yoshihisa , Hoshi Akihiko , Sakamoto Kiyohiko
Published: August 2010

The results of treating 54 esophageal carcinomas with low‐dose rate telecobalt therapy (LDRT) as a boost were compared with those of treating 97 esophageal carcinomas with conventionally fractionated irradiation alone (CFI). The LDRT (100 cGy/hr, 500 to 700 cGy/day, a total dose of 1400 to 2000 cGy) was boosted at 10 days after 6000 cGy of the CFI dose. Although the LDRT group included more advanced cases than the CFI group, local effects and survival rates in the former group were slightly better than in the latter group. Late complications were more severe in the LDRT group. However, they were acceptable when the total dose administered to this group was less than 8000 cGy. Using LDRT as a boost against esophageal carcinomas was found to be satisfactory therapeutically.
T‐cell chronic lymphocytic leukemia: T‐cell function and lymphokine secretion
Authors: Raziuddin Syed , Sheikha Anwar , Latif Abdulbasit A.
Published: August 2010

The leukemic T‐celis of the six patients with T‐cell chronic lymphocytic leukemia (T‐CLL), four with CD4 and CD45R‐positive (CD4+ CD45R*) T‐CLL and two with CD8 and CD45R‐positive (CD8+ CD45R+) T‐CLL pheno‐type were studied for detailed immunologic phenotypic and functional characteristics. The levels of soluble in‐terleukin‐2 receptors were elevated significantly in the serum of all four patients with CD4+ CD45R+ T‐CLL. Moreover, the CD4+ CD45R+ T‐CLL patients' T‐cells, after in vitro stimulation with phytohemagglutinin and concanavalin A, expressed elevated percentages of interieukin‐2 receptors on cells and secreted high interleukin‐2 activity. The B‐cell growth factor (BCGF) activity from three patients with CD4+ CD45R+ T‐CLL was enhanced, but B‐cell differentiation factor (BCDF) activity of the all T‐CLL patients was decreased. Reduced BCGF and BCDF activity of the leukemic T‐cells was one possible mechanism of hypogammaglobulinemia detected in two patients with T‐CLL. All T‐CLL patients' leukemic T‐cells had diminished immunoregulatory functional activity in allogeneic mixed lymphocyte reactions. These observations suggest that leukemic T‐cells from T‐CLL patients have many immunologic functional defects that may be important in their proliferative potential.
Low incidence of human papillomavirus type 16 DNA in bladder tumor detected by the polymerase chain reaction
Authors: Chetsanga C. , Malmström P.‐U. , Gyllensten U. , Moreno‐Lopez J. , Dinter Z. , Pettersson U.
Published: August 2010

Human papillomavirus (HPV) detection was done using the polymerase chain reaction technique on tumor tissue from 44 patients with transitional cell carcinoma of the urinary bladder. Only one of the 44 was associated with HPV infection. The HPV‐positive patient was not known to have immunodeficiency or genital warts, and the tumor was not morphologically different from the other tumors. Control experiments excluded the possibility that this finding was caused by contamination of the sample. This study confirms that HPV infection is a. rare condition in bladder carcinoma.

Descriptions of personal experiences: Effects on students' learning and behavioral intentions toward peers with Attention‐Deficit/Hyperactivity Disorder
Authors: Saecker Lee B. , Skinner Amy L. , Skinner Christopher H. , Rowland Emily , Kirk Emily
Published: August 2010

High‐school students were shown an educational video designed to dispel 12 common myths regarding Attention‐Deficit/Hyperactivity Disorder (ADHD) by describing each myth and then presenting accurate information. The experimental group viewed a video that was supplemented by the speaker acknowledging that he had ADHD and providing descriptions of personal experiences (DPE) designed to highlight the injury caused by 6 of the 12 common myths. Findings suggest that including the DPE may have enhanced learning of the information that was highlighted by these descriptions, but interfered with learning the other six facts. Providing DPE did not alter behavioral intentions, and this analysis did not appear to be confounded by differential learning. Our discussion focuses on personalizing disability information, seductive details effects, and the role that correcting myths with accurate information may have on students with respect to their interactions with classmates with disabilities. © 2010 Wiley Periodicals, Inc.
Effectiveness of Aquatic Exercise for Obese Patients with Knee Osteoarthritis: A Randomized Controlled Trial
Authors: Lim Jae‐Young , Tchai Esther , Jang Soong‐Nang
Published: August 2010

Objective

To design an aquatic exercise (AQE) and land‐based exercise (LBE) program to enhance knee function and reduce body fat in patients with obesity and knee osteoarthritis and to investigate the effectiveness of AQE and LBE on body fat, functional fitness, and functional status.

Setting

Outpatient clinic at a Seoul National University Bundang Hospital.

Participants

Obese patients with knee osteoarthritis were recruited from patients who visited the rehabilitation, orthopedic surgery, and geriatric outpatient clinics at the hospital. Study participants were limited to those who met the following criteria: body mass index more than 25 kg/m2, abdominal circumference more than 90 cm (men) or 85 cm (women), clinically diagnosed osteoarthritis with Kellgren–Lawrence scale 2 or higher on radiographic studies, and independent ambulation state.

Methods

Participants were randomly allocated into 3 groups: AQE (n = 26), LBE (n = 25), and the control group (n = 24). Exercise interventions were conducted 3 times a week for 8 weeks.

Outcome Measures

Body fat analysis, brief pain inventory, Western Ontario and McMaster Universities' osteoarthritis index, Short Form‐36 questionnaire, and knee isokinetic tests were evaluated to assess changes in body fat composition, pain, physical function, and quality of life before and after the exercise program.

Results

Although no significant difference was found in general characteristics among the 3 groups before exercise, body fat proportion in the AQE group decreased significantly (mean ± SD, from 34.4 ± 4.7 to 33.3 ± 4.7; P = .031) after intervention. The body mass index was slightly reduced after intervention, but it was not statistically significant. The AQE group showed significant improvements in pain, disability, and quality of life. Notably, the change in pain interference in the AQE group (mean ± SD, from 25.8 ± 15.1 to 18.8 ± 13.1; P = .009) was greater than that of the LBE group. Both exercise groups showed significant improvements in Western Ontario and McMaster Universities' osteoarthritis index disability compared with the control group.

Conclusions

AQE had an advantage in controlling the interference with activity because of pain. AQE may be an effective tool for patients with obesity who have difficulties with active exercise due to knee osteoarthritis.
Rehabilitation Outcomes of Stroke Patients Treated With Tissue Plasminogen Activator
Authors: Meiner Zeev , Sajin Anna , Schwartz Isabella , Tsenter Jeanna , Yovchev Ivelin , Eichel Roni , Ben‐Hur Tamir , Leker Ronen R.
Published: August 2010

Objective

To investigate the influence of thrombolysis on functional outcomes after rehabilitation.

Background

Systemic thrombolysis with tissue plasminogen activator (tPA) is considered the mainstay of acute stroke therapy and was found to improve short‐term outcome.

Design

Matched case‐controlled design.

Setting

Inpatient neurology and rehabilitation departments.

Participants

Thirty‐seven patients given tPA and 37 control patients not treated with lytics because of protocol limits.

Methods

We retrospectively analyzed data from a cohort of stroke patients who were treated with systemic tPA. The rehabilitation outcome of thrombolysis‐treated patients was compared with that observed for tPA‐ineligible and age‐ and stroke severity‐matched patients treated at the same neurology and rehabilitation departments.

Main Outcome Measure

Neurological evaluation was assessed with the National Institutes of Health stroke scale (NIHSS). Activity of daily living was measured using the Functional Independence Measure (FIM) instrument. Functional outcome was measured using the modified Rankin scale (mRS).

Results

The treatment group included 37 patients given tPA; 37 tPA‐ineligible patients served as controls. On admission to rehabilitation, there were no significant differences in functional, neurological, and rehabilitation parameters between the groups. At the end of the rehabilitation period, NIHSS scores were significantly lower in the thrombolysis group (P = .036). More patients in the thrombolysis group reached functional independence defined as mRS ≤2 (20/37 versus 10/37; P = .03). At the end of rehabilitation, total FIM score (mean 102.8 versus 93.9; P = .039), total FIM gain (mean 27.8 versus 21.4; P = .09), and total FIM efficiency scores (0.8 versus 0.43; P = .013) were higher in the thrombolysis group and more patients in this group were discharged home.

Conclusions

Although the bulk of neurological improvement occurred before the inpatient rehabilitation, thrombolysis‐treated patients continue to improve faster and to a larger extent during the rehabilitation period suggesting that the beneficial effects of thrombolysis continue beyond the acute phase.
The Interplay of Experience-Based Affective and Probabilistic Cues in Decision Making
Authors: Glöckner Andreas , Hochman Guy
Published: August 2010

In a study using behavioral and physiological measures we induced experience-based affective cues (i.e., differential anticipatory arousal) toward a risky and a safe option by letting participants repeatedly select between two decks of cards with feedback. In later test decisions we presented choice tasks between these trained and new pairs of decks. In some of the trials a low-valid probabilistic cue was provided after stimulus onset but before the decision. Although we were successful in inducing experience-based affective cues these did not influence participants’ choices. In decisions without any further cues available people choose the safe and the risky option about equally often. If an additional low-valid probabilistic cue was available people followed this cue. Although experience had no effect on choices it influenced arousal. Anticipatory physiological arousal increased if the probabilistic cue and experience were conflicting. Our results are in line with recent findings indicating diminished loss aversion in experience-based decision making. They are also consistent with parallel constraint satisfaction models and shed light on the interrelation between experience, probabilistic cues, and arousal in decision making.

Published: August 2010

We present a coarse grain representation for Gaussian chains in the presence of hard surfaces. Whereas a Gaussian chain in the bulk can be represented by a bead-spring model with a quadratic potential between adjacent beads, the presence of a surface reduces the number of allowed chain configurations and modifies the effective potential between the beads. We derive the corrected potentials for several surface geometries: a single wall, two parallel walls (slit), and a spherical or cylindrical object (nanoparticle). Those potentials can be used in any model that includes a Gaussian chain, regardless of the simulation method. As an illustration, we consider a coarse grain model of a polymeric melt and, using Monte Carlo simulations, we compute the density profiles for (i) a melt confined in a slit and (ii) a melt in the vicinity of a nanoparticle. The case of a polymeric solution confined within a slit is also addressed, and the proposed approach is shown to yield results in qualitative agreement with those obtained with field-theoretic simulations.
Quantum oscillatory exciton migration in photosynthetic reaction centers

Published: August 2010

The harvesting of solar energy and its conversion to chemical energy is essential for all forms of life. The primary photon absorption, transport, and charge separation events, which trigger a chain of chemical reactions, take place in membrane-bound photosynthetic complexes. Whether quantum effects, stemming from entanglement of chromophores, persist in the energy transport at room temperature, despite the rapid decoherence effects caused by environment fluctuations, is under current active debate. If confirmed, these may explain the high efficiency of light harvesting and open up numerous applications to quantum computing and information processing. We present simulations of the photosynthetic reaction center of photosystem II that clearly establish oscillatory energy transport at room temperature originating from interference of quantum pathways. These signatures of quantum transport may be observed by two dimensional coherent optical spectroscopy.
Lattice thermal conductivity of freestanding gallium nitride nanowires
Authors: Zou Jie
Published: August 2010

We report detailed calculations of the lattice thermal conductivity of freestanding gallium nitride (GaN) nanowires with diameters ranging from 20 to 140 nm. Results are compared with experimental data on GaN nanowires grown by thermal chemical vapor deposition (CVD). Calculations are based on the Boltzmann transport equation and take into account the change in the nonequilibrium phonon distribution in the case of diffuse scattering at the surfaces. Phonon dispersion relation is obtained in the elastic continuum approximation for each given nanowire. For valid comparisons with the experimental data, simulations are performed with a dopant concentration and impurity profile characteristic of thermal CVD GaN nanowires. Our results show that the room-temperature thermal conductivity of the nanowires has very low values, ranging from 6.74 W/m K at 20 nm to 16.4 W/m K at 140 nm. The obtained results are in excellent agreement with the experimental data. We have also demonstrated that in addition to impurity scattering, boundary scattering, and phonon confinement, the change in the nonequilibrium phonon distribution leads to a further reduction in the thermal conductivity of the nanowires and has to be taken into account in the calculations. Our conclusion is different from that of an earlier study which attributed the very low thermal conductivity to the unusually large mass-difference scattering in the nanowires.
Spin-adapted open-shell random phase approximation and time-dependent density functional theory. I. Theory
Authors: Li Zhendong , Liu Wenjian
Published: August 2010

The spin-adaptation of single-reference quantum chemical methods for excited states of open-shell systems has been nontrivial. The primary reason is that the configuration space, generated by a truncated rank of excitations from only one component of a reference multiplet, is spin-incomplete. Those “missing” configurations are of higher ranks and can, in principle, be recaptured by a particular class of excitation operators. However, the resulting formalisms are then quite involved and there are situations [e.g., time-dependent density functional theory (TD-DFT) under the adiabatic approximation] that prevent one from doing so. To solve this issue, we propose here a tensor-coupling scheme that invokes all the components of a reference multiplet (i.e., a tensor reference) rather than increases the excitation ranks. A minimal spin-adapted n-tuply excited configuration space can readily be constructed by tensor products between the n-tuple tensor excitation operators and the chosen tensor reference. Further combined with the tensor equation-of-motion formalism, very compact expressions for excitation energies can be obtained. As a first application of this general idea, a spin-adapted open-shell random phase approximation is first developed. The so-called “translation rule” is then adopted to formulate a spin-adapted, restricted open-shell Kohn–Sham (ROKS)-based TD-DFT (ROKS-TD-DFT). Here, a particular symmetry structure has to be imposed on the exchange-correlation kernel. While the standard ROKS-TD-DFT can access only excited states due to singlet-coupled single excitations, i.e., only some of the singly excited states of the same spin (Si) as the reference, the new scheme can capture all the excited states of spin Si−1, Si, or Si+1 due to both singlet- and triplet-coupled single excitations. The actual implementation and computation are very much like the (spin-contaminated) unrestricted Kohn–Sham-based TD-DFT. It is also shown that spin-contaminated spin-flip configuration interaction approaches can easily be spin-adapted via the tensor-coupling scheme.

Published: August 2010

We have investigated the absorption of 0.9–1.4 nm silicon carbide nanoparticles (SiC NPs) by time-dependent density functional calculations, focusing on the effect of various oxygen adsorbates of the surface. We have found that SiO and CO single bonds result in relatively large optical gaps in the ultraviolet region while SiO and CO double bonds will dramatically lower the optical gap into the visible blue and red regions, respectively. Our findings can help interpret recent experiments on colloidal SiC NPs and their utilization in biological applications.

We reveal the low-temperature anomaly in the temperature and angular dependencies of the coercivity in granular (CoFeB)x–(SiO2)1−x films with oriented in-plane anisotropy. Namely, at T<100 K the in-plane angular dependence of coercive field acquires two maxima corresponding to easy and hard (in a film plane) directions. This signifies the emergence of coercivity for hard direction in a film plane. The experimental results are explained in terms of a random field model, which describes the onset of spin glass-like correlations in the ensemble of oriented weakly interacting Stoner–Wohlfarth particles.

Published: August 2010

Different imaging modes of low temperature laser scanning microscopy (LTLSM) have been applied to probe local optical and superconducting properties, as well as the spatial variations in thermoelectric and electronic (both dc and rf) transport, in a YBa2Cu3O6.95/LaAlO3 (YBCO/LAO) superconducting microstrip resonator with micron-range resolution. Additionally, the local sources of microwave nonlinearity (NL) were mapped in two-dimensions simultaneously by using the LTLSM in two-tone rf intermodulation distortion contrast mode as a function of (x,y) position of the laser beam perturbation on the sample. The influence of the direction of individual twin-domain YBCO blocks on its NL properties was analyzed in detail. The result shows the direct spatial correlation between NL microwave and dc electronic transport properties of the YBCO film that are imposed by the underlying twin-domain topology of the LAO substrate. In these circumstances, the scale of local NL current densities JIM(x,y) in different areas of the YBCO microstrip quantitatively coincide with the scale of local critical current densities Jc(x,y) measured at the same positions.

We study the anomalous acoustic softening behavior in La68−xCexAl10Cu20Co2 (x=0, 34, and 68) metallic glasses by magnetic susceptibility, thermal expansion, and specific heat at low temperatures. The Ce-based metallic glass exhibits valence fluctuation phenomenon, anomalous thermal expansion and acoustic Grüneisen parameter at low temperatures. And we provide experimental evidence of the existence of strong electron–phonon coupling in the Ce-based metallic glasses by specific heat. The anomalous acoustic and thermal properties are attributed to the valence instability in the metallic glasses.
Theory and simulation of the dynamic heat capacity of the east Ising model
Authors: Brown Jonathan R. , McCoy John D. , Borchers Brian
Published: August 2010

A recently developed methodology for the calculation of the dynamic heat capacity from simulation is applied to the east Ising model. Results show stretched exponential relaxation with the stretching exponent, β, decreasing with decreasing temperature. For low temperatures, the logarithm of the relaxation time is approximately proportional to the inverse of the temperature squared, which is the theoretical limiting behavior predicted by theories of facilitated dynamics. In addition, an analytical approach is employed where the overall relaxation is a composite of relaxation processes of subdomains, each with their own characteristic time. Using a Markov chain method, these times are computed both numerically and in closed form. The Markov chain results are seen to match the simulations at low temperatures and high frequencies. The dynamics of the east model are tracked very well by this analytic procedure, and it is possible to associate features of the spectrum of the dynamic heat capacity with specific domain relaxation events.
Conical intersections of free energy surfaces in solution: Effect of electron correlation on a protonated Schiff base in methanol solution

Published: August 2010

The minimum energy conical intersection (MECI) optimization method with taking account of the dynamic electron correlation effect [T. Mori and S. Kato, Chem. Phys. Lett. 476, 97 (2009)] is extended to locate the MECI of nonequilibrium free energy surfaces in solution. A multistate electronic perturbation theory is introduced into the nonequilibrium free energy formula, which is defined as a function of solute and solvation coordinates. The analytical free energy gradient and interstate coupling vectors are derived, and are applied to locate MECIs in solution. The present method is applied to study the cis-trans photoisomerization reaction of a protonated Schiff base molecule (PSB3) in methanol (MeOH) solution. It is found that the effect of dynamic electron correlation largely lowers the energy of S1 state. We also show that the solvation effect strongly stabilizes the MECI obtained by twisting the terminal CN bond to become accessible in MeOH solution, whereas the conical intersection is found to be unstable in gas phase. The present study indicates that both electron correlation and solvation effects are important in the photoisomerization reaction of PSB3. The effect of counterion is also examined, and seems to be rather small in solution. The structures of free energy surfaces around MECIs are also discussed.

Published: August 2010

The hot-electron thermopower of a quantum point contact (QPC) is exploited for full-wave rectification at low temperatures. In a nanoscale AlGaAs/GaAs cross junction with orthogonal current and voltage leads the QPC is embedded into one voltage lead. The transfer resistance RT, given by the output voltage divided by input current, exhibits a distinct maximum at finite current and at gate voltages close to the QPC pinch-off voltage. Values in excess of RT=7 kΩ and output voltages up to 60% of the input voltages indicate an efficient ballistic rectification process.

Published: August 2010

We present an experimental study on the effect of optical feedback in both ground and excited emission of a GaAs quantum dot passively mode locked laser. The experimental setup consisted of a long external cavity with variable cavity length and feedback level ranging from –50 to –20dB. The obtained experimental results show dependence of the emission properties on the cavity length regarding both the ground and excited state. In addition a strong tolerance of the laser operation to feedback at the excited state operation regime is observed.

Published: August 2010

The authors report on high quality ZnCdO alloy epilayers and ZnCdO/ZnO single quantum well structures on sapphire substrates by pulsed laser deposition. The Cd concentration in the ZnCdO alloy can be systematically adjusted via the substrate temperature and single-phase ZnCdO alloy with a band gap at room temperature extended to 2.94 eV is achieved. The single quantum well structures exhibit strong photoluminescence from the well layer with extremely weak emission from deep level defects and the ZnO barrier, indicating the high quality of ZnCdO/ZnO single quantum well structures.
