Adjunctive use of mitomycin C on endoscopic lacrimal surgery

AIMS Endoscopic endonasal dacryocystorhinostomy (DCR) has some advantages over external DCR as a less invasive method with no skin incisions. But the success rate of the operation has not reached the level of external method. In this study, a wound healing inhibitor mitomycin C was used intraoperatively to prevent the closure of the osteum after the operation. METHODS Endoscopic endonasal DCR was performed on 40 eyes of 39 patients (26 female, 13 male). Mitomycin C was applied to the ostium in 14 of 23 patients who had undergone primary endoscopic DCR by means of a microdrill and in eight of 17 patients who had a revision endoscopic DCR secondary to a previously failed external DCR. RESULTS The postoperative follow up period was 9–27 (mean 18.2) months. The success rate of endoscopic DCR with intraoperative mitomycin C was 77.3%, whereas the success rate of endoscopic DCR without mitomycin C was 77.8%. The statistical analysis did not show a difference between the two groups according to the ostium size and their success rates. CONCLUSIONS Adjunctive use of a wound healing inhibitor is considered to increase the success rate of endoscopic endonasal DCR. Its intraoperative use seems to be easy and safe. But the study of this limited series shows no benefit in using it.
A Study on relationships among Parent-adolescent communication, Self Differentiation, Self Esteem, Life Stress in Nursing department students

Abstract The purpose of this study was to explore relationship among communication with parent, self differentiation, self esteem, life stress in nursing department students. Data were collected from 305 nursing department students and analyzed using descriptive statistics, t-test, ANOVA, Bonferroni's test, Pearson's correlation coefficients and multiple regressions with the SPSS/WIN 18.0 program. Stress frequency differed according to stress importance, self differentiation, self esteem. Hierarchical multiple regression analysis showed stress importance, self differentiation, self esteem explained 38.6% of the total variance in stress frequency. The findings indicate that stress importance, self differentiation, self esteem have an influence on stress frequency. We need to develop and provide nursing intervention programs to decrease college student's stress. Key words : Nursing students, Communication, Self differentiation, Self esteem, Life stress 1. 서론 현대사회가 산업화되고 정보화되면서 환경의 변화는 극심해지고 복잡한 사회구조 속에서 사람들은 다양한 갈등을 경험하면서 여러 가지 스트레스에 시달리고 있다. 그 중에서도 대학생들은 대학에 진학하면서부터 부모의 보호에서 벗어나 스스로의 행동과 사고에서 책임감이 뒤따르고 자율성 또한 요구받게 되어 대학생활 적응에 어려움을 느끼게 된다[24]. 또한 대학생이 되면서 가정이나 사회로부터 능동적이고 책임감을 가진 사회인으로서의
Heart failure from diastolic dysfunction related to hypertension: Guidelines for management

Purpose To provide advanced practice nurses with a greater understanding of the pathophysiology, diagnostics, and management of diastolic dysfunction resulting from hypertension. Data sources Electronic database searches were performed using Medline and CINAHL. Data were obtained from medical textbooks and research and review articles. Conclusions As the number of older adults with heart failure (HF) continues to increase, so will the need for effective care and guidance. In addition to further testing of appropriate pharmacologic regimens, adherence factors such as medication costs and patients’ functional abilities must be considered. Implications for practice HF resulting from diastolic dysfunction has emerged as a separate entity over the past 10–15 years. One of the most common causes of diastolic dysfunction is uncontrolled hypertension. Populations at greatest risk include elders, particularly women, and African Americans.
Performing arithmetic functions with the Chinese abacus approach

-This brief introduces a novel (or ancient) technique for highspeed arithmetic. The new proposed method is based on the still-used Chinese abacus. We show that proper electronic circuits, based on pass transistor and domino logic, allow us to achieve the same functions of the Chinese abacus. Simulations with a 0.35-/spl mu/m CMOS technology show that either a pipeline 8-bit adder and 8/spl times/8 multiplier can run at a speed as high as 1 GHz.
C/EBPδ targets cyclin D1 for proteasome-mediated degradation via induction of CDC27/APC3 expression

The transcription factor CCAAT/enhancer binding protein δ (C/EBPδ, CEBPD, NFIL-6β) has tumor suppressor function; however, the molecular mechanism(s) by which C/EBPδ exerts its effect are largely unknown. Here, we report that C/EBPδ induces expression of the Cdc27 (APC3) subunit of the anaphase promoting complex/cyclosome (APC/C), which results in the polyubiquitination and degradation of the prooncogenic cell cycle regulator cyclin D1, and also down-regulates cyclin B1, Skp2, and Plk-1. In C/EBPδ knockout mouse embryo fibroblasts (MEF) Cdc27 levels were reduced, whereas cyclin D1 levels were increased even in the presence of activated GSK-3β. Silencing of C/EBPδ, Cdc27, or the APC/C coactivator Cdh1 (FZR1) in MCF-10A breast epithelial cells increased cyclin D1 protein expression. Like C/EBPδ, and in contrast to cyclin D1, Cdc27 was down-regulated in several breast cancer cell lines, suggesting that Cdc27 itself may be a tumor suppressor. Cyclin D1 is a known substrate of polyubiquitination complex SKP1/CUL1/F-box (SCF), and our studies show that Cdc27 directs cyclin D1 to alternative degradation by APC/C. These findings shed light on the role and regulation of APC/C, which is critical for most cellular processes.
Friction and friction compensation in the Furuta pendulum

Inverted pendulums are very well suited to investigate friction phenomena and friction compensation because the effects of friction are so clearly noticeable. This paper analyses the effect of fiction on the Furuta pendulum. It is shown that friction in the arm drive may cause limit cycles. The limit cycles are well predicted by common friction models. It is also shown that the amplitudes of the limit cycles can be reduced by friction compensation. Compensators based on the Coulomb friction model and the LuGre model are discussed. Experiments performed show that reduction of the effects of friction can indeed be accomplished.
Radixin regulates cell migration and cell–cell adhesion through Rac1

Summary The ERM proteins ezrin, radixin and moesin are adaptor proteins that link plasma membrane receptors to the actin cytoskeleton. Ezrin and moesin have been implicated in cell polarization and cell migration, but little is known about the involvement of radixin in these processes. Here we show that radixin is required for migration of PC3 prostate cancer cells, and that radixin, but not ezrin or moesin, depletion by RNA interference increases cell spread area and cell–cell adhesion mediated by adherens junctions. Radixin depletion also alters actin organization, and distribution of active phosphorylated ezrin and moesin. Similar effects were observed in MDA-MB-231 breast cancer cells. The phenotype of radixin-depleted cells is similar to that induced by constitutively active Rac1, and Rac1 is required for the radixin knockdown phenotype. Radixin depletion also increases the activity of Rac1 but not Cdc42 or RhoA. Analysis of Rac guanine nucleotide exchange factors (GEFs) suggests that radixin affects the activity of Vav GEFs. Indeed, Vav GEF depletion reverses the phenotype of radixin knockdown and reduces the effect of radixin knockdown on Rac1 activity. Our results indicate that radixin plays an important role in promoting cell migration by regulating Rac1-mediated epithelial polarity and formation of adherens junctions through Vav GEFs.
Reduced-order pattern representation of UWB antenna devoted to positioning

An ultra-wideband antenna and array are designed for positioning applications. The antennas are supposed to be placed against a wall; hence, pattern stability and low back-radiation are among the design criteria. Simulations are compared to measurements at the level of impedance of a single antenna. Several compact representations of the patterns are considered. As for intermediate accuracy, a dipole based representation is found to require fewer parameters than spherical-wave decompositions.
A New Threshold Multisignature Scheme for Mobile Ad Hoc Networks

#1 Professor, Dean-Faculty of Applied Science, National University of Rwanda, Rwanda Corresponding Author: dsdawoud@gmail.com PhD Student, University of Waterloo, Canada, Dr. Consultant – SA Dr. Senior Lecturer – National University of Rwanda ABSTRACT Mobile ad hoc networks offer communication over a shared wireless channel without any preexisting infrastructure. Threshold digital signatures are an important cryptographic tool used in most existing key management schemes for mobile ad hoc networks. This paper proposes a threshold-multisignature scheme designed specifically for mobile ad hoc networks. The signature scheme allows a subset of shareholders with threshold t, to sign an arbitrary message on behalf of the group. The group signature is publicly verifiable and allows any outsider to establish the identity of the individual signers. The paper proposes a self-certified public key issuing protocol that allows negotiation between a single entity and a distributed certificate authority for an implicit self-certified public key. The results of this paper will be extended and used in (Dawoud et al, 2011b), to introduce a public key management that is suitable for ad hoc networks.
A Computational Psycholinguistic Model of Natural Language Processing

Double R Model (Referential and Relational model) is a computational psycholinguistic model of NLP founded on the principles of Cognitive Linguistics and implemented using the ACT-R cognitive architecture and modeling environment. Despite its psycholinguistic basis, Double R Model is intended for use in the development of large-scale, functional language comprehension systems. Given the inherently human nature of language, this approach may be reasonable from an AI as well as a psycholinguistic point of view.
Imaging Prevalence of Sigmoid Sinus Dehiscence among Patients with and without Pulsatile Tinnitus

Objective Define the radiographic prevalence of sigmoid sinus diverticulum or dehiscence (SSDD) in patients with and without pulsatile tinnitus (PT). Study Design Case series with chart review. Setting Tertiary care university medical center. Subjects Patients imaged between January 1, 2003, and December 31, 2012. Methods Two groups were evaluated for SSDD. The first (“PT”) included patients whose radiology report indicated a clinical history of PT (n = 37 symptomatic ears in 30 patients). The second (“non-PT”) included all patients undergoing temporal bone high resolution CT (HRCT) between November 2011 and November 2012 (n = 308 ears in 164 patients) for reasons other than pulsatile tinnitus. Primary outcome measure was the radiographic presence of SSDD. Covariates including age, gender, body mass index (BMI), and audiometric data were analyzed by independent t tests and Fisher’s exact test. Results Within the PT group, SSDD was identified in 24% of ears (9/37) and 23% of patients (7/30); all SSDD patients were female (P = .024). Patients with SSDD were significantly younger (P = .037). SSDD more frequently caused objective tinnitus (P = .016). There was no difference in average BMI between those with and those without SSDD. In the non-PT group, SSDD was identified in 2 (both female) of 164 patients (1.2%; 0.6% of ears). The difference in SSDD prevalence between groups was significant (P < .0001). Conclusions The prevalence of SSDD in patients with PT was 23%. Among patients with PT, those with SSDD were younger, exclusively female, and presented with objective tinnitus. The prevalence of SSDD among asymptomatic patients in 1 year was 1.2%.
A novel approach for location promotion on location-based social networks

Maximizing the spread of influence was recently studied in several models of social networks. For location-based social networks, it also plays an important role, so a further research about this field is necessary. In this study, based on users' movement histories and their friendships, we first design the Predicting Mobility in the Near Future (PMNF) model to capture human mobility. Human mobility is inferred from the model by taking into account the following three features: (1) the regular movement of users, (2) the movement of friends of users, (3) hot regions, the most attractive places for all users. Second, from the result of predicting movements of users at each location, we determine influence of each user on friends with the condition that friends are predicted to come to the location. Third, the Influence Maximization (IM) algorithms are proposed to find a set of k influential users who can make the maximum influence on their friends according to either the number of influenced users (IM num) or the total of probability of moving the considered location of influenced users (IM score). The model and algorithms are evaluated on three large datasets collected by from 40,000 to over 60,000 users for each dataset over a period of two years in the real world at over 500,000 checked-in points as well as 400,000 to nearly 2,000,000 friendships also considered. The points are clustered into locations by density-based clustering algorithms such as OPTICS and GRID. As a result, our algorithms give an order of magnitude better performance than baseline approaches like choosing influential users based on the number of check-ins of users and selecting influential users by the number of friends of users. From the result of experiments, we are able to apply to some areas like advertisement to get the most efficient with the minimum costs. We show that our framework reliably determines the most influential users with high accuracy.
[Impact of insulin resistance on prognosis in non-diabetic patients with acute coronary syndromes].

OBJECTIVE To evaluate the impact of insulin resistance (IR) on prognosis in non-diabetic acute coronary syndrome patients. METHODS In this prospective study, we enrolled 332 non-diabetic patients suffering from acute coronary syndrome. The patients were divided into three groups by HOMA-IR which calculated by formula: low HOMA-IR group (HOMA-IR < 2), 44 cases; moderate HOMA-IR group (2 ≤ HOMA2-IR < 6), 99 cases; high HOMA-IR group (HOMA ≥ 6) with HOMA index, 179 cases. The in-hospital medical records of patients were compared, and all patients were followed up for one year after discharge. RESULTS Incidence of hypertension (P = 0.013), dyslipidemia (P < 0.001), faster resting heart rate (P < 0.001) and number of triple vessel coronary artery disease (P = 0.017) in high HOMA-IR group were significantly higher than in low and moderate HOMA-IR group. During follow-up, the major end-point events increased in proportion to IR grade: 64.3% (26/44) in the high HOMA-IR group, 54.7% (52/99) in moderate HOMA-IR group and 41.3% (74/199) in low HOMA-IR group (P = 0.034). Multivariable logistic regression analysis showed that high sensitivity C reactive protein (OR = 1.012, 95%CI:1.002-1.022, P = 0.022), HOMA-IR (OR = 1.250, 95%CI:1.043-1.497, P = 0.015) , triple vessel coronary artery disease (OR = 5.914, 95%CI:2.947-11.868, P < 0.001) , ischemic changes on ECG (OR = 5.495, 95%CI:2.925-10.324, P < 0.001) and low left ventricular ejection fraction (LVEF ≤ 40%) (OR = 13.205, 95%CI:5.000-34.661, P < 0.001) were independent risk factor for major end-point events during follow-up. CONCLUSIONS Increased insulin resistance is linked with poor prognosis of non-diabetic patients with acute coronary syndrome.
Masking Disrupts Reentrant Processing in Human Visual Cortex

In masking, a stimulus is rendered invisible through the presentation of a second stimulus shortly after the first. Over the years, authors have typically explained masking by postulating some early disruption process. In these feedforward-type explanations, the mask somehow catches up with the target stimulus, disrupting its processing either through lateral or interchannel inhibition. However, studies from recent years indicate that visual perceptionand most notably visual awareness itselfmay depend strongly on cortico-cortical feedback connections from higher to lower visual areas. This has led some researchers to propose that masking derives its effectiveness from selectively interrupting these reentrant processes. In this experiment, we used electroencephalogram measurements to determine what happens in the human visual cortex during detection of a texture-defined square under nonmasked (seen) and masked (unseen) conditions. Electro-encephalogram derivatives that are typically associated with reentrant processing turn out to be absent in the masked condition. Moreover, extrastriate visual areas are still activated early on by both seen and unseen stimuli, as shown by scalp surface Laplacian current source-density maps. This conclusively shows that feedforward processing is preserved, even when subject performance is at chance as determined by objective measures. From these results, we conclude that masking derives its effectiveness, at least partly, from disrupting reentrant processing, thereby interfering with the neural mechanisms of figure-ground segmentation and visual awareness itself.
A Compile-Time Scheduling Heuristic for Interconnection-Constrained Heterogeneous Processor Architectures

The authors present a compile-time scheduling heuristic called dynamic level scheduling, which accounts for interprocessor communication overhead when mapping precedence-constrained, communicating tasks onto heterogeneous processor architectures with limited or possibly irregular interconnection structures. This technique uses dynamically-changing priorities to match tasks with processors at each step, and schedules over both spatial and temporal dimensions to eliminate shared resource contention. This method is fast, flexible, widely targetable, and displays promising performance. >
The adolescent brain and the college drinker: biological basis of propensity to use and misuse alcohol.

OBJECTIVE This article reviews the literature on adolescent brain development and considers the impact of these neural alterations on the propensity to use and misuse alcohol. METHOD Neural, behavioral and hormonal characteristics of adolescents across a variety of species were examined, along with a review of the ontogeny of ethanol responsiveness, tolerance development and stress/alcohol interactions. RESULTS The adolescent brain is a brain in transition. Prominent among the brain regions undergoing developmental change during adolescence in a variety of species are the prefrontal cortex and other forebrain dopamine projection regions, stressor-sensitive areas that form part of the neural circuitry modulating the motivational value of alcohol and other reinforcing stimuli. Along with these characteristic brain features, adolescents also exhibit increased stressor responsivity and an altered sensitivity to a variety of ethanol effects. Findings are mixed to date as to whether exposure to ethanol during this time of rapid brain development alters neurocognitive function and later propensity for problematic ethanol use. CONCLUSIONS Developmental transformations of the adolescent brain may have been evolutionarily advantageous in promoting behavioral adaptations to avoid inbreeding and to facilitate the transition to independence. These brain transformations may also alter sensitivity of adolescents to a number of alcohol effects, leading perhaps in some cases to higher intakes to attain reinforcing effects. These features of the adolescent brain may also increase the sensitivity of adolescents to stressors, further escalating their propensity to initiate alcohol use. Additional investigations are needed to resolve whether ethanol use during adolescence disrupts maturational processes in ethanol-sensitive brain regions.
Lightweight, low cost GaAs solar cells on 4″ epitaxial liftoff (ELO) wafers

GaAs single junction solar cells were fabricated on epitaxial liftoff (ELO) 4:″ GaAs wafers. 1 cm2 single junction GaAs solar cells have been fabricated with a yield ≫80% across full 4″ ELO wafers. Photoluminescence studies of ELO GaAs wafers showed no evidence of residual strain in the layers as indicated by single peak at 870 nm at 300 K. Transmission electron microscopy studies of ELO solar cells indicated no evidence of threading dislocations, voids or delaminating at the semiconductor-metal interface. Quantum efficiency measurements on ELO GaAs single junction solar cells indicated improved performance near the band edge in the ELO samples compared with conventional, non-ELO GaAs cells. GaAs ELO solar cells exhibited efficiencies in excess of 21% with Voc = 1.007 V and FF≫85%.

System Architectures, Protocols and Algorithms for Aperiodic Wireless Control Systems

Wide deployment of wireless sensor and actuator networks in cyber-physical systems requires systematic design tools to enable dynamic tradeoff of network resources and control performance. In this paper, we consider three recently proposed aperiodic control algorithms which have the potential to address this problem. By showing how these controllers can be implemented over the IEEE 802.15. 4 standard, a practical wireless control system architecture with guaranteed closed-loop performance is detailed. Event-based predictive and hybrid sensor and actuator communication schemes are compared with respect to their capabilities and implementation complexity. A two double-tank laboratory experimental setup, mimicking some typical industrial process control loops, is used to demonstrate the applicability of the proposed approach. Experimental results show how the sensor communication adapts to the changing demands of the control loops and the network resources, allowing for lower energy consumption and efficient bandwidth utilization.
Improving CNN Performance with Min-Max Objective

In this paper, we propose a novel method to improve object recognition accuracies of convolutional neural networks (CNNs) by embedding the proposed Min-Max objective into a high layer of the models during the training process. The Min-Max objective explicitly enforces the learned object feature maps to have the minimum compactness for each object manifold and the maximum margin between different object manifolds. The Min-Max objective can be universally applied to different CNN models with negligible additional computation cost. Experiments with shallow and deep models on four benchmark datasets including CIFAR- 10, CIFAR-100, SVHN and MNIST demonstrate that CNN models trained with the Min-Max objective achieve remarkable performance improvements compared to the corresponding baseline models.
Articulatory Parameters

The production of speech is constrained by the articulatory parameters that people can vary. It is suggested that there are seven parameters affecting tongue shapes, three determining the positions of the lips, one controlling the position of the velum, four varying laryngeal actions, and one controlling respiratory activity. Descriptions of all linguistic utterances can be made in terms of about 16 parameters.
