706 Lymphocyte subpopulations in patients with primary versus post-embolic pulmonary hypertension: a pilot study

Aim: To evaluate and compare cell-mediated immunity in patients with primary and post-embolic pulmonary arterial hypertension (PAH). Methods: Flow cytometry and measurement of endothelin 1, thromboxane B2 and 6-ketoprostaglandin F1a levels was performed in 16 patients with idiopathic PAH [iPAH] and 12 with post-embolic PAH [pePAH]. Results: CD3+ numbers (mature T-lymphocytes) were slightly reduced in both groups (see Table), with the reduction being significantly more frequent in iPAH than in pePAH patients (100% vs. 83% patients, p < 0,001). The same pattern followed numbers of CD3+CD4+ (T-helpers/inducers) (100% vs. 50%, p < 0,05) and of CD3+CD8+ (cytotoxic T-cells) (66% vs. 42% patients, p < 0,01). There were similar reductions of CD50+ and increases of CD3+CD25+ (activated lymphocytes) in both groups, and no significant abnormalities in CD3–CD16+ (NK cells), CD19+ (B-cell) numbers and CD4/CD8 ratio. Phagocytic activity was at the lower normal limit in both groups. Phagocytic counts correlated with endothelin 1 levels (r=0,41, p < 0,002) and with thromboxane B2 and 6-ketoprostaglandin F1a (r = -0,46, p < 0,001 and r = -0,3, p < 0,05, respectively). Table. No title available. Conclusion: This data indicates potential defectiveness of lymphatic cellular interactions more evident in iPAH than in pePAH. Functional level of cellular immunity is associated with vasoactive endothelial mediators.
A Novel High K Inter-Poly Dielectric(IPD), A1203 for Low VoltageMigh Speed Flash Memories: Erasing in msecs at 3.3V

We propose a novel high K dielectric, A1203 for low voltage/ high speed flash memory without built-in charge pumps. From the analytical modeling, we have quantified the impact of high K IPD and we have verified the feasibility of 10-11 nm A1203 IPD with K-10 for msecs erasing at k3.3V. We have also developed lOnm A1203 films which show the lowest leakage current ever reported for the dielectrics with K>5 [ 131. For the first time, high K dielectric has been demonstrated for high retention fish technology.
OPTICAL ACOUSTIC INVESTIGAITON OF FEMTOSECOND LASER PULSE INTERACTION WITH BIOLOGICAL TISSUES

The results of experimental optical acoustic investigation of femtoand nanosecond pulses attenuation by some biological tissues (muscular tissue, adipose tissue, cutaneous covering, milk) and optical breakdown thresholds on these one are presented. It was shown that penetration depth of short laser pulse radiation into biological tissues is the same as for longer one. However, amplitude of acoustic response to a process of interaction of femtosecond laser pulse with biological tissue is larger in several times than that to interaction with nanosecond pulses of the same power and spectral distribution. The obtained of threshold values can be interesting for tabulation of limit allowable levels of irradiation at work with laser radiation. Such values are unknown for femtosecond laser pulses today.
A 0.5-1V MTCMOS/SIMOX SRAM Macro with Multi-Vth Memory Cells

high-Vth one are also shown for comparison. The noise margins of both memory cells deceasc for reducing the supply voltage. But, the noise margin of the multi-Vth memory cell is more than twice that of the conventional one because the read-port of the multi-Vth cell does not affect the data-hold itode of the cell. The characteristics of the power dissipation of the multiplexer are shown in Fig. 5. The increase of'the Vth makes possible the reduction of the power dissipation of the multiplexer. When the threshold voltage is increased i'rom 0.15 to 0.35 V, the multiplexer can reduce the power dissipation by 60 % at 1 V and 80 % at 0.5 V. The delay-time characteristics of the multiplexer are shown in Fig. 6. The capacitance of the bit-line connected to the multi-Vth nlemory cell composed of SO1 devices with small junction capacitance is smaller than that of a memory cell composed of bulk devices. At 0.5 V, the delay time of the rnultiplexer of the SO1 SRAM with the bit-line capacitance of 0.4 pF, which comesponds to the sum of a row of 512 memory cells, is less than 75% that of the bulk SRAM with the bit-line capacitance of 0.8 pF. To verify the effectiveness of the multi-Vth memory cell scheme, we designed and fabricated a 64-Kb SRAM with 0.35-pm MTCMOS/SIMOX technology. The thicknesses of the gate-oxide, the active silicon layer, and the buriedoxide in the SIMOX-wafer are 7, 50, and 100 nm, respectively. The absolute values of the threshold voltage of lowand high-Vth MOSFETs are 0.15 and 0.35 V. A microphotograph of the SRAM is shown in Pig. 7 (a). The memory cell is 30% larger than the conventional single-port cell. The shmoo plots for evaluating the maxirnum operating frequency are shown in Fig. 7 (b). The maximum operating frequencies of over 100 and 20 MHz were confinned at the supply voltages of I and 0.5 V. The power consuniptions are 8 mW and 0.4 mW, respectively. The power consumption in the sleep mode is less than 0. I pW. The features of the SRAM are sunimarized in Table. Acknowledgment
Analysis of fractal radiation patterns from concentric-ring hexagonal arrays

Abstract. These hexagonal arrays are becoming increasingly popular, especially for their applications in the area of wireless communications. The overall objective of this article has been to use the theoretical foundation developed for the analysis of radiation patterns and design of the hexagonal arrays. A technique has been developed for the analysis of radiation patterns from concentric ring arrays. A family of functions, known as generalized Weierstrass functions, has been shown to play a key role in the theory of fractal radiation pattern analysis.
Local Sagittal Alignment after Indirect Reduction and 2-Level Short-Segment Pedicle Screw Fixation of Thoracolumbar Burst Fractures

Local Sagittal Alignment after Indirect Reduction and 2-Level Short-Segment Pedicle Screw Fixation of Thoracolumbar Burst Fractures The treatment of thoracolumbar burst fractures with short-segment pedicle screw fixation alone has been associated with progressive loss of correction and instrumentation failure. However, some burst fractures can be treated successfully by this technique without correction loss or implant failure.
Strain Engineering for 2D Ferroelectricity in Lead Chalcogenides

The quest for new 2D ferroelectric materials continues to arouse interest. Based on first‐principles calculations, here, 2D ferroelectric properties in lead chalcogenides PbXs (X = S, Se, and Te) with a thickness of two atomic layers via strain engineering is demonstrated. Although these materials are stable in a rocksalt‐type cubic structure and are intrinsically nonferroelectric materials, an appropriate mechanical strain can readily activate a paraelectric to ferroelectric phase transition and induce in‐plane electric polarization in these atomic layers. The induced polarization magnitude can be as large as 1.90 × 10−10 C m−1 at a biaxial strain of ε = 4.0%, which is comparable in magnitude to that of ultrathin ferroelectric SnTe. The Curie temperature Tc of the materials is also estimated using effective Hamiltonian simulations. The origin of the emerged ferroelectric phase is attributed to softening of the polar mode with applied strain. In addition, the band gaps of the crystals are found to be tunable with applied strain, which can be adjusted to the ideal value of 1.3 eV for photovoltaic applications. The results not only provide a new route to explore ferroelectricity in 2D materials but also suggest promising semiconducting ferroelectrics for solar applications.
Mexican American Mothers' Perceptions of their Role in Childhood Obesity Prevention: A Qualitative Study

Despite myriad preventive efforts, childhood obesity rates continue to increase and disproportionately affect Mexican American children. Mothers can be very influential in preventing childhood obesity especially within the home. Home is where children first learn normative behaviors, including dietary and physical activities. Three focus groups with 23 Mexican American mothers were conducted in Bryan, TX to assess perceptions of childhood obesity prevention. Thematic analysis of interview transcripts was conducted. Mothers acknowledged they were primarily responsible for their children’s health and weight. However, they also identified barriers to obesity prevention and were unsure of which strategies were best for encouraging children to eat vegetables and be physically active. Mothers can be catalysts to obesity prevention, but programs need to provide the education, skill set, and opportunities to make these differences.
The Great Transformation of Central Eastern Europe

The study examines the changes of the Central Eastern European region first in the context of world history. It confirms by comparative historical analyses that the transformation was indeed unique. This has been the only total transformation that took place peacefully, without violence, and at the same time astonishingly fast, in the main direction of the economic and the political changes of Western civilization. From that perspective it is an exceptional success story. However, from the perspective of everyday life, the result is different. Deep economic troubles are experienced by a considerable portion of the population. The perception of losses is intensified by various cognitive problems. Based on the experience of today's generation, evaluating the change as an unequivocal success would be unwarranted. Both approaches are justified: it would be wrong to blend the two and to weigh them by the same scale. Copyright (c) The European Bank for Reconstruction and Development, 2006.
Highlight of primary and secondary relaxations in amorphous stereocomplex polylactides

A racemic mixture of two stereoregular polylactides (PLAs) ( i.e. PLLA and PDLA) allows obtaining wholly amorphous stereocomplex PLA films by solvent casting method. The amorphous phase behavior of stereocomplex PLA is compared with that of PLLA and PDLA by advanced thermal analysis, such as Fast Scanning Calorimetry (FSC) and Dielectric Relaxation Spectroscopy (DRS). FSC allows us to quench at very high cooling rate (up to 4000 K·s –1 ) the studied polymers and to obtain glassy amorphous phases with high excess of enthalpy. It is shown that stereocomplexation has no influence on the glass transition temperature, the physical aging and on the cooperativity. The α and β processes were examined to study the dielectric properties, such as relaxation time, dielectric strength, and fragility. The results of FSC and DRS are correlated to determine the values of cooperativity length which are found to be similar in a wide temperature range. It is found that the studied polymers have the similar dielectric properties independently on their tacticity.

Trimodal electroencephalogram during isoflurane anaesthesia

Abstract The effects of common anaesthetic agents, such as isoflurane or propofol, on the electroencephalogram are well-known. The most characteristic feature is the marked increase in delta power and alpha power resulting in a bimodal power spectrum from light to moderately deep anaesthesia. Here, a case is presented where the power spectrum became trimodal when anaesthesia was lightened towards wake up. The implications of a third mode for depth-of-anaesthesia monitoring are discussed. Its neuro-physiology is unknown, as it has never been reported before.
Treatment of femoral neck fractures in young adults

Objective To explore one convenient and effective way to treatment of femoral neck fractures in young adults.Methods Twenty-six cases of femoral neck fractures in young and middle aged adults were treated by pin of bone and iliac osteoperiosteal flap pedicled with deep iliac circumflex blood vessel.Results Twenty-six cases showed excellent outcomes after following up for 10 month～5 years.The femoral neck fractures had been healed.There was no ischemic necrosis of femoral head.Their functions on the hips were satisfactory.Conclusion Femoral neck fractures in young adults are severe injuries because the ruined local blood circulation hampers healing and results in high rate of the ischemic necrosis of femoral head.The multiple muscle pedicle iliac bone graft is helpful for young adults with femoral neck fractures in that it can accelerate bone healing,reduce the rate of the ischemic necrosis,and improve curative effects.
Life Style and Perception of Obesity of Male White Collar Workers

Background : This study investigated and analyzed the life style of male white- collar workers and their perception of obesity to determine how to improve eating habits and prevent obesity. Materials and Methods : Using the questionnaires distributed to and collected from 300 male white-collar workers in Daegu, the survey was conducted from December 20, 2005 to February 28, 2006. Two hundred sets of collected questionnaires were used for the analysis, and SPSS WIN 12.0 was employed to analyze the data. Results : Forty-two percent of subjects had weights ranging between 71 kg and 80 kg; 39.5%, weighted between 61 kg and 70 kg. The waist measurements of 64.5% of all respondents were between 32 and 34 inches. The lifestyle questions found that 54% of respondents were smokers and 88.5% drank alcohol. In addition, 62.5% of all respondents reported doing exercise, whereas 37.5% reported no exercise. Conclusion : The height and weight of 200 respondents were used to calculate the body mass index (BMI). Only 31.6% had a normal BMI, whereas 32% were found to be overweight, a condition likely to lead to obesity. Meanwhile, 36.5% of respondents were obese or morbidly obese.
Humidity sensors based on ZnO/TiO(2) core/shell nanorod arrays with enhanced sensitivity

Highly aligned arrays of ZnO/TiO(2) core/shell nanorods were fabricated on glass substrates by hydrothermal growth of ZnO nanorods cores followed by the deposition of anatase TiO(2) shells in a sol-gel process. The characterization of these composite materials with scanning electron microscopy (SEM), Raman spectroscopy, X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX) and transmission emission microscopy (TEM) points to the formation of crystalline ZnO nanorod cores that are coated with anatase TiO(2) shells. Humidity sensors based on these core/shell nanorod arrays exhibit outstanding sensitivities with capacitances varying from 10(1) to 10(6) pF over a relative humidity (RH) range of 11%-95% at room temperature, which is 1.5 and 3 orders of magnitude higher than that of pristine TiO(2) films and ZnO nanorods, respectively. Complex impedance analysis indicated that the enhanced humidity sensitivity is probably due to the high surface/volume ratio of this core/shell material in combination with the remarkable hydrophilicity of the TiO(2) shell.

Investigation of Notch Dept Effect on Domain Wall Depinning in Ferromagnetic Nanowires by Micromagnetic Simulation

Utilization of topological nanostructure such as magnetic domain wall (DW) as a future generation of non-volatile memory as racetrack memory has been attracted more researchers due to potential to achieve higher speed of data read/writing and capacity. However, completed understanding of DW dynamics was still need to be improved by advanced analysis from the theoretical/simulation or experimental methods. In this study, the effect of geometrical notch dept on domain wall depinning in Permalloy (Py) nanowires by micromagnetic simulation method have been investigated. The varied double notch dept from 10 to 90 nm in 200 nm of wire width were used and the transverse type DW was triggered by nanosecond current pulse to observe the critical depinning current (Jd). It is observed that the depinning current was increased as the notch dept increases. However, the magnitude of Jd have a maximum values for all notch length variation. The increasing of notch length has shifted the maximum Jd to the larger notch dept values. This behavior indicated that the optimum notch design was needed to obtain higher speed and lower depinning energy in the development of domain wall based devices.
Structure of the IBEX Ribbon from Distributed Sources

The Interstellar Boundary Explorer (IBEX) mission discovered the presence of a global structure in energetic neutral atom emissions from the outer heliosphere not predicted by any model – the IBEX “ribbon”. In the search for possible explanations, observations have pointed to a likely source from neutral atoms produced through charge-exchange with the outflowing solar wind. The secondary (neutral) solar wind then undergoes charge-exchange beyond the heliopause to produce the proton population that forms the ribbon. Here we study the plasma structure beyond the heliopause created from distributed secondary neutral atom sources. We provide a framework to analyze the IBEX ribbon taking into account distributed neutral atom sources within the local interstellar medium.
Chemical preparation, thermal behavior and infrared studies of the new cyclotriphosphate tetrahydrate of manganese and distrontium, MnSr2(P3O9)2.4H2O

A new cyclotriphosphate tetrahydrate of manganese and distrontium, MnSr2(P3O9)2.4H2O, was obtained as a polycrystalline sample by the method of ion-exchange resin. The cyclotriphosphate studied in this work is the second one having the formula MnSr2(P3O9)2.4H2O after BaZn2(P3O9)2.10H2O. Its crystallographic characterization, infrared studies and thermal behavior are given. The studied phosphate crystallizes in the triclinic system, P-1, with the following unit cell parameters : a = 6,653(1)Å, b = 7,110(1)Å, c = 5,123(1)Å, a = 103,37(2)°, b = 95,81(2)°, g = 93,04(2)° and Z = 1. The intermediate products of dehydration of MnSr2(P3O9)2.4H2O are MnSr2(P3O9)2.2H2O, mixture of ([Mn(PO3)2]∞ + 2g [Sr(PO3)2]∞) and mixture of ([Mn(PO3)2]∞ + 2b[Sr(PO3)2]∞). The thermal behavior of the studied condensed phosphate has been investigated and interpreted by IR absorption and X-ray diffraction experiments. The title compound can be used as catalyst, ion exchanger, the reactant in ionic conditions, intercalation reactions, superphosphate fertilizer and as an inorganic pigment in ceramics.
Redesigning Teacher Education in the Context of Multiple Reform Initiatives

Numerous teacher educators are revising their programs by focusing on high-leverage practices (HLPs). Concurrently, edTPA has been adopted by a number of states as a way to assess teacher candidates’ readiness to teach. There is considerable conceptual congruence in these reform strategies. Both are practice-based, focusing on the authentic work of teaching. Nonetheless, the origins of these strategies, language, and materials are not seamless. HLPs, and ways of teaching them, are generated by local teacher educators themselves; edTPA was developed on a national scale with one purpose being to provide a common assessment of readiness to teach. This chapter illustrates the collective efforts of one teacher education program to productively handle the challenges that emerge in this dual reform climate while simultaneously meeting accreditation association requirements, including a conceptual framework for educator preparation programs. A model is subsequently presented for meaningful integration of edTPA, HLPs, and institutional conceptual frameworks.
Use of High Titer RSV immunoglobulin (RI-001-RSV-IVIG) in Immunocompromised Adults

Immunocompromised patients are at high risk for serious sequelae due to RSV infection. Patients with hematologic malignancies,solid organ and hematopoetic stem cell transplant (HSCT) recipients are particularly susceptible to fulminant infection. The reported mortality rate in pre-engraftment HSCT patients who develop RSV-LRTI can be as high as 70-100% without treatment. Inhaled Ribavirin and standard IVIG have been used in the treatment of RSV disease with some success; however, morbidity and mortality remain high in this patient population. RespiGam® (high titer RSV IVIG) was first introduced in the United States in 1996, but was voluntarily withdrawn from the market by the manufacturer in December 2003 after the introduction of Palivizumab. Because Palivizumab is dosed by weight, its use in adults is prohibitively expensive.
The Firehawk Stent: A Review of a Novel Abluminal Groove-Filled Biodegradable Polymer Sirolimus-Eluting Stent

Despite recent advances in drug-eluting stent (DES) technology, late adverse events remain concerns after percutaneous coronary intervention. The persistence of polymer material on DES has been suggested as a trigger for chronic inflammation. The Firehawk, a novel DES, has a unique design with recessed abluminal grooves, to which sirolimus and biodegradable polymer are applied. The Firehawk stent is designed to minimize polymer volume and antiproliferative drug concentration to reduce inflammation and hypersensitivity reactions. Several recent trials have reported the clinical outcomes of this device. This article provides a review of the current clinical evidence concerning the Firehawk stent.
Effect of Sago Starch Concentrations, Stirring Speeds, and Lemongrass Oil Concentration for Edible Film Production Using Solvent Casting Method

Foods such as meat, fillet, fruit and vegetable tend to have short shelf life when it is stored outside without packaging. Recently, edible film and coating become a potential alternative for food packaging. Edible film brings a lot of advantages from environmental aspect because it is easier to be decomposed rather than the synthetic film. Furthermore, edible film might be produced from both natural raw material and waste materials. Edible film from natural raw material gives a rigid structure. Another additive agent must be used to make a better quality product, such as glycerol and lemon grass oil as plasticizer and antimicrobial agent, respectively. These materials are commonly used in edible film production due to its capability for extending the food shelf-life by inhibiting bacterial growth. The objectives of this study are to investigate the effect of starch concentration (3% to 10% w/v), stirring speed (350, 700, 1100 rpm) and lemon grass oil concentration (1%, 5% v/v) on tensile strength, water vapor permeability, and antimicrobial activity. Results show that 4% (w/v) sago starch gives the best edible film mechanical properties and least water transfer. Edible film with 4% (w/v) sago starch, 8 rpm constant stirring, and 5% (v/v) lemongrass oil gives the best result in tensile strength, water vapor permeability and bacterial growth. In addition, variables of starch concentration, stirring speed and lemon grass oil concentration are interrelated to produce the best edible film.
