The combined use of Nd:YAG laser and enamel matrix proteins in the treatment of periodontal infrabony defects.

BACKGROUND The objective of regenerative periodontal therapy is the reconstitution of lost periodontal structures, such as cementum, periodontal ligament, and alveolar bone. Enamel matrix proteins (EMP) are used as a local adjunct to periodontal surgery to stimulate regeneration of periodontal tissues lost to periodontal disease. The aim of this split-mouth study evaluates and compares the healing of intrabony defects after treatment with an EMP with or without neodymium-doped:yttrium-aluminum-garnet (Nd:YAG) laser application for root surface conditioning. METHODS Forty-two intrabony defects in 21 patients with chronic periodontitis were randomly assigned to an access flap surgery with application of Nd:YAG laser (1 W, 10 Hz, 100 mJ, 1064 nm) and EMP (test group), and on the contralateral defect to an access flap surgery with application of EDTA and EMP alone (control group). Clinical periodontal parameters were assessed at baseline and after 6 and 12 months. RESULTS Both treatments yielded significant improvements in terms of decrease in probing depth (PD) and gain in clinical attachment level (CAL) compared to baseline values. At 12 months after therapy, in the test group, the mean PD value was reduced from 7.3 ± 0.6 to 3.3 ± 0.4 mm and the mean CAL value changed from 9.5 ± 0.7 to 6.9 ± 0.7 mm (P <0.001). The sites treated with EMP (control) showed a reduction in mean PD value from 7.3 ± 0.7 to 3 ± 0.4 mm and a change in mean CAL value from 9.3 ± 0.8 to 6.4 ± 0.5 mm (P <0.001). The control group showed a greater reduction in PD and gain in CAL compared to the test group (P <0.05). CONCLUSION Within the limits of the present study, it may be concluded that both therapies led to improvements of the clinical parameters, and Nd:YAG laser root conditioning as used in this study compared to EDTA root conditioning did not improve the outcome of EMP use.
Optimal reactive power dispatch using particle swarm optimization with time varying acceleration coefficients

In this paper a particle swarm optimization with time varying acceleration coefficients (PSO-TVAC) algorithm is applied to solve the optimal reactive power dispatch problem (ORPD). The ORPD problem is formulated as nonlinear, non-convex constrained optimization problem considering both continuous and discrete control variables, also it has both equality constraints and inequality constraints. The acceleration coefficients in PSO algorithm are varied adaptively during iterations to improve solution quality of original PSO and avoid premature convergence. The feasibility of the proposed algorithm has been tested on the IEEE 14-bus and IEEE-118 bus test systems. Moreover, the obtained results are compared with those available recently in the literature.
A cell surface antigen expressed by astrocytes and their precursors

Increasing evidence suggests that astrocytes of the mammalian CNS are a heterogeneous population of cells that express a number of common characteristics. In most cases, astrocytes or their precursors contain a class of intermediate filaments, composed in large part of glial fibrillary acidic protein (GFAP). While the expression of GFAP immunoreactivity is a specific characteristic of astrocytes in the vertebrate CNS, not all astrocytes contain detectable levels of glial filaments, particularly during early development. We have isolated a monoclonal antibody termed 7B11 which binds to the surface of astrocytes and glial precursors, but not to other major types of neural cells. The 7B11 antigen is expressed by astrocytes in the adult CNS in vivo and in cultures of developing CNS tissue, but not on cells of the peripheral nervous system. During early development, 7B11 immunoreactivity appears prior to the expression of GFAP and is retained as punctate staining on the surface of most classes of astrocytes. During CNS maturation, however, 7B11 immunoreactivity is lost from the surface of Bergmann glia in the cerebellum, suggesting that differentiative events lead to functionally and anti‐genically distinct classes of CNS glial cells. In the adult spinal cord, biochemical analysis suggests that the epitope recognized by 7B11 is associated with a group of polypeptides of apparent molecular weights 200‐160, 140, and 92 kD. The cellular distribution of 7B11 expression suggests that astrocytes and their precursors share a distinct cell surface antigenic property and that the expression of 7B11 immunoreactivity may be a useful operational marker for astrocytes in the absence of detectable GFAP expression. © 1993 Wiley‐Liss, Inc.
Care of the elderly in United Arab Emirates

The United Arab Emirates (UAE) is a small, highincome country with rich natural resources. The country enjoys peace, stability and actively seeks and facilitates investment from all over the world. It is considered by many to be the new commercial hub of the Middle East. The gross national income increased from 4.7 billion AED in 1972 to 229 billion AED in 2002, with an annual growth rate of 13.8%. Non-oil sectors contributed 188 billion AED in 2002 compared to 2.4 billion AED in 1972. Health care services are supported by the state and are regulated by seven different federal agencies each representing one emirate. The government fully supports health care services for all citizens and recent law has made medical insurance coverage obligatory for all expatriates. Life expectancy is 76 years for male and 79 years for females. The country has a very good vaccination program and enjoys a low maternal and below 5-year mortality rate (WHO, 2007). According to world health statistics (2008), only 2.9% of UAE overall population (nationals and expatiates) are older than 65. However, according to UAE ministry of health estimation, 13% of the indigenous UAE indigenous population (about 850 000) are older than 65. In neighboring Saudi Arabia, this figure is estimated to be around 7% (WHO, 2007; UAE, 2008; http://www.moh.gov.ae/en/Page_342.aspx). Similar to most countries around the world, the number of elderly people is predicted to increase in the coming decades and caring for them will obviously put a significant pressure on health care systems.
Design of algorithm of inverse viewing transformation with using multistage correlation analysis of stereoimage

Today, according to product automatisation systems, which are used for building of three dimension models of technological environment, enginery and machinery, became widespread. Many modern fast - acting scanning laser systems are used only in unmanned situations because of danger for human. It means development of passiv optical systems of three - dimensional vision. In this work algorithm of inverse viewing transformation is suggested, which based on determination unknown parameters of system of equations for point in three - dimensional space: v(x, y, z) = (ρ<inf>1</inf>, ρ<inf>2</inf>, ϕ<inf>1</inf>, ϕ<inf>2</inf>, θ<inf>1</inf>, θ<inf>2</inf>, d)· w(x<inf>1</inf>, x<inf>2</inf>, y<inf>1</inf>, y<inf>2</inf>), where w - vector of screen coordinates, v - vector of coordinates of point in three - dimensional space, A - generalized matrix of rotation and transfer [1]. Common area of images is detected using correlation analysis [2, 3] with optimization of computational complexity and growing of data accuracy on each step of calculation of correlation function of images of object.
Single Cell Analysis of Factor VIII-specific T Cells in Hemophilic Mice after Treatment with Human Factor VIII

Summary A multi-parameter flow-cytometry assay was established suitable for analyzing T-cell-specific cell surface markers (CD3, CD4) together with intracellular cytokines on a single cell level. This assay was used to identify the frequency and the kinetic of different populations of factor VIII (FVIII)-specific CD4+ T cells in hemophilic E-17 mice after treatment with human FVIII. A clear temporal correlation was found between the appearance of FVIII-specific CD4+ T cells in the spleen and the detection of anti-FVIII antibodies in plasma. These cells and antibodies were detectable in all experiments after two doses of FVIII and in a few even after a single dose. The IFN-γ- producing T cells were the most prominent type of FVIII-specific T cells suggesting Th1-type T cells have an important role in regulating the anti-FVIII immune response in E-17 mice. IL-10-producing T cells were the second most dominant type. They were detectable after two doses of FVIII and increased in frequency after four. Cytokine co-expression studies analyzing IL-10 and IFN-γ- in the same cell indicated that there might be at least two types of IL-10 positive T cells, those cells that produce IL-10 only and in addition cells that produce IL-10 and IFN-γ-. Furthermore, FVIII-specific T cells producing IL-2 were found in all experiments after two doses of FVIII. In a few experiments IL-4-producing T cells were seen but in most experiments they were not detectable. In contrast, IL-4 could be found in supernatants of in vitro restimulated CD8– spleen cells.
RETHINKING RACISM: TOWARD A STRUCTURAL INTERPRETATION *

The study of race and ethnic conflict historically has been hampered by inadequate and simplistic theories. I contend that the central problem of the various approaches to the study of racial phenomena is their lack of a structural theory of racism. I review traditional approaches and alternative approaches to the study of racism, and discuss their limitations. Following the leads suggested by some of the alternative frameworks, I advance a structural theory of racism based on the notion of racialized social systems. "The habit of considering racism as a mental quirk, as a psychological flaw, must be abandoned. " -Frantz Fanon (1967:77) he area of race and ethnic studies lacks a _ sound theoretical apparatus. To complicate matters, many analysts of racial matters have abandoned the serious theorization and reconceptualization of their central topic: racism. Too many social analysts researching racism assume that the phenomenon is selfevident, and therefore either do not provide a definition or provide an elementary definition (Schuman, Steeh, and Bobo 1985; Sniderman and Piazza 1993). Nevertheless, whether implicitly or explicitly, most analysts regard racism as a purely ideological phenomenon.
Impact of subband quantization on DPD correction performance

The digital predistortion (DPD) is a technique to linearize the response of power amplifiers which is the subject of an active research. In order to model accurately and properly linearize the PA, the ADC in the feedback path must digitize the distorted signal with an adequate resolution and bandwidth. The multi-stage noise band cancellation (MSNBC) ΣΔ architecture is able to provide a signal digitized by subbands and where the subbands may be digitized with different resolutions. We show that the correction performance can be maintained while different quantization for the main high power subband and for the low power subbands are used resulting in a more flexible and low power consumming solution.
Differential signaling mechanisms of HNP‐induced IL‐8 production in human lung epithelial cells and monocytes

Human neutrophil peptides (HNP) kill microorganisms but also modulate immune responses through upregulation of the chemokine IL‐8 by activation of the nucleotide P2Y6 receptor. However, the intracellular signaling mechanisms remain yet to be determined. Human lung epithelial cells (A549) and monocytes (U937) were stimulated with HNP in the absence and presence of the specific kinase inhibitors for Src, extracellular signal‐regulated kinase‐1 and ‐2 (ERK1/2), p38 mitogen‐activated protein kinase (MAPK), c‐Jun‐N‐terminal kinases (JNK), and Akt. HNP induced a rapid phosphorylation of the kinases in both cell types associated with a dose‐dependent, selective production of IL‐8 among 10 cytokines assayed. The HNP‐induced IL‐8 production was blocked by the Src tyrosine kinase inhibitor PP2, MEK1/2 inhibitor U0126, and the phosphatidylinositol 3 kinase (PI3K) inhibitor LY294002, but not by the JNK inhibitor SP600125 in both cell types. Treatment with the p38 inhibitor SB203580 attenuated the HNP‐induced IL‐8 production only in monocytes. Blockade of Src kinase blunted HNP‐induced phosphorylation of the ERK1/2 and Akt but not p38 in monocytes. In contrast, Src inhibition had no effect on phosphorylation of the other kinases in the lung epithelial cells. We conclude that the activation of ERK1/2 and PI3K/Akt pathways is required for HNP‐induced IL‐8 release which occurs in a Src‐independent manner in lung epithelial cells, while is Src‐dependent in monocytes.

Severe Thrombocytopenia in a Child Secondary to Passive Platelet Antibody Transfer from a Plasma Transfusion

Although rare, passive transfer of platelet antibodies through blood products can result in thrombocytopenia, acute transfusion reactions, and death. We report a case of severe alloimmune thrombocytopenia from a plasma transfusion. A postliver transplant patient with a normal platelet count received fresh frozen plasma before liver biopsy. Postbiopsy, she developed cardiorespiratory distress, petechiae, and severe thrombocytopenia (platelet count 2000/&mgr;L). Her platelet count recovered to normal after 1 week. This diagnosis should be considered whenever an unexpected drop in the platelet count occurs after a plasma-rich transfusion. Conservative transfusion practices and more targeted donor screening may prevent similar events.
Rabbit supraspinatus motor endplates are unaffected by a rotator cuff tear

Rotator cuff tears are a major cause of morbidity. Following rotator cuff tears, muscle atrophy and fatty infiltration begin in the tissue, limiting repair potential and leading to a higher re‐tear rate and a worse functional outcome. We evaluated whether fatty degeneration resulting from a complete supraspinatus tear with retraction is associated with an injury to the suprascapular nerve. Four skeletally mature New Zealand white rabbits were randomized to receive an index procedure on either their right or left shoulder with the opposite shoulder serving as a control. At the index procedure, the supraspinatus tendon was transected at its insertion and allowed to retract. At 3 months, the rabbits were euthanized, and both supraspinatus muscles were harvested. The specimens were then examined with confocal microscopy and histology. Atrophy was grossly visible in all four test muscles, and fatty infiltration was confirmed with osmium tetroxide staining. In all four rabbits, the degree of denervation (p = 0.71) and partial denervation (p = 0.91) was not significantly different between control and experimental muscle. Rotator cuff tear does not affect the motor endplate or innervation status of the supraspinatus. Fatty infiltration occurs independent of denervation of the supraspinatus. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 31:99–104, 2012
DETERMINATION OF ENZYME ACTIVITIES IN FOUR SELECTED GRAINS ( RICE , MILLET , SORGHUM AND MAIZE ) AT VARIOUS GERMINATION STAGES

The content of starch and the activities of enzymes involved in starch biosynthesis were examined in germinating grains of field grown rice, sorghum, millet and maize plants. Enzyme activities were monitored throughout the grain germinating periods for three days. The activities of most of the grain enzymes involve in starch biosynthesis increased and reached their maxima during the initial period of grain development, then gradually declined towards the later stages of grain germination.
Complex congenital heart disease after in vitro fertilization.

Sir . —Congenital heart disease is a rare complication in newborns conceived by in vitro fertilization and embryo transfer. 1-3 We describe a patient with a complex congenital heart disease born after this procedure. The mother was 28 years old and had had previous abortions that caused infertility. The blastocystic implantation was accomplished in Rome, at another institution. The newborn, a chromosomically normal female, was born at the 34th week of gestation following an uncomplicated pregnancy. Delivery was normal, and birth weight was 2300 g. Cyanosis was noted at birth, and cardiac catheterization revealed pulmonary atresia with a large ventricular septal defect. The pulmonary arteries were supplied by a ductus arteriosus, the aorta arose completely from the right ventricle surrounded by a muscular infundibulum, and a persistent left superior vena cava drained into the left atrium through an unroofed coronary sinus. The patient underwent a right Blalock-Taussig shunt as a neonate,
[Integrated treatment of traditional Chinese medicine and western medicine for early- and intermediate-stage diabetic nephropathy].

OBJECTIVE To study the therapeutic effect of traditional Chinese herbal medicinal preparation Tangshenqing (TSQ) combined with alprostadil in the treatment of early- and intermediate-stage diabetic nephropathy (DN). METHODS One hundred and twenty DN patients were randomized into 3 groups for different treatment protocols. The patients in the control group were given the basic treatment (low-protein diabetic diet and rigorous control of blood glucose, blood pressure, and blood fatty acid), and those in treatment group A received TSQ (containing Astragalus membranaceus, Panax notoginseng, Epimedium brevicornum, etc) in addition to the basic treatment, and those in treatment group B were treated with alprostadil injections (for 14 consecutive days) in addition to the treatment given in group A. Therapeutic effect evaluation was carried out after a 30-day treatment in all the patients. RESULTS The overall efficaey rate of the treatment was 78.37% in the control group, 88.57% in the treatment group A, and 94.44% in treatment group B, suggesting better therapeutic effect in the latter two groups than in the control group (P<0.05). Patients in all the 3 groups exhibited symptomatic improvement of various degrees, but the treatment group B had the best results. After the treatments, the patients' blood glucose and fatty acids were lowered, without obvious difference between the 3 groups. Compared with the control group, the patients in the two treatment groups showed significant reduction in fibrinogen, 24-h urine microprotein and urine protein after the treatment (P<0.01 or 0.05). CONCLUSION Combined use of traditional Chinese herbal medicine TSQ and alprostadil injections produces definite therapeutic effect on early- to intermediate-stage DN.

Adaption for 2-D Edge Elements in the Nonconforming Voxel Finite-Element Method

The nonconforming voxel finite-element (FE) method avoids many of the difficulties of traditional FE mesh generation using a nested grid of rectangular elements. It models arbitrary boundary shapes by adaptively refining the mesh at the boundaries. Here, the adaption is extended to reduce errors arising from elements that are away from boundaries, but are too big to represent the field adequately. The application is to 2-D edge elements for solving the time-harmonic wave equation. Results for a miter-bend waveguide and a dielectric post resonator demonstrate the effectiveness of the new algorithm.
A 22-dBm 24-GHz power amplifier using 0.18-µm CMOS technology

A fully integrated 24-GHz 22-dBm power amplifier was designed and fabricated in 0.18-µm CMOS technology. Optimized device size selection and resonance matching techniques are adopted in this single stage power amplifier design. High pass matching circuit is used to reduce output losses and maintain gain flatness. The measurement results shows a 22 dBm of saturation power and 20 dBm of output power at 1 dB compression point with peak PAE of 20% under 3.6 V bias supply. To the best of author's knowledge, this PA demonstrates the highest output power and highest PAE at 1 dB compression among the reported CMOS PAs in this frequency range.

Person X situation interactionism in self-encoding (I am...when...): implications for affect regulation and social information processing.

Although Person X Situation (P X S) interactionism is central in current social-cognitive conceptions of personality organization, its implications for the encoding of the self remain unexplored. Two studies examined the causal role of P X S interactionism in self-encoding on affect regulation and discriminative social perception. Following failure (Studies 1 and 2) and success (Study 2) ideation, participants were prompted to encode the self either in P X S interactionist terms (I am.when.) or in traitlike unconditional terms (I am.). Interactionist (compared with unconditional) self-encoding led to less affective extremity, suggesting that such encoding may prevent individuals from generalizing specific success and failure experiences to the self as a whole. Study 2 also found that interactionist self-encoding attenuated the endorsement of global stereotypes, suggesting that such encoding may enhance fine-grained social perception as well.
Power Traces Clipping and Splicing Enhanced Correlation Collision Analysis

Correlation enhanced Collision Attacks (CCA) can be able to exploit any first-order leakage without knowing the precise hypothetical power model. However, the correlation between time samples of two S-boxes is relatively weak, which leads to the low efficiency of CCA. Actually, the efficiency of CCA is much lower than that of Correlation Power Analysis (CPA). In this paper, two methods named Invalid Power Traces Clipping based CCA (IPTC-CCA) and Power Traces Splicing based CCA (PTS-CCA) are proposed to improve the efficiency of CCA. IPTC+PTS-CCA, a combination of IPTC-CCA and PTSCCA, which is more efficient than both stand-alone IPTC-CCA and PTS-CCA, is also proposed in this paper. Experiments on the power trace set of Rotating S-boxes Masking (RSM) protected AES-256 algorithm implemented on the Side-channel Attack Standard Evaluation Board (SASEBO) from the website DPA contest v4 show that the 3 schemes proposed in this paper can significantly improve the efficiency of CCA.
