Evaluation of the use of low-level laser therapy in pain control in orthodontic patients: A randomized split-mouth clinical trial
Authors: Farias Rodrigo Duarte , Closs Luciane Quadrado , Miguens Sergio Augusto Quevedo 
Published: July 2015

ABSTRACT

Objective:
To evaluate the effect of using low-level laser therapy (LLLT) to control pain and discomfort during orthodontic treatment.

Materials and Methods:
A randomized, split-mouth clinical trial was conducted with 30 volunteers in need of orthodontic treatment, of both genders, aged between 18 and 40 years, who were randomly divided into two groups. One hemiarch was considered the exposed group (EG) and the other, the placebo group (PG). Both groups had elastic separators placed mesially and distally to the first molars of the two hemiarches at different times. The EG received an AIGaAs diode LLLT (810 nm, 100 mW, 2J/cm2) application for 15 seconds per point (interdental papilla at the mesial, distal, and near the root apex) immediately after separator placement on the maxillary right side. The PG also had elastics placed around the maxillary right molars, but received only simulated LLLT application. The elastics were left in place for 5 days, and after a waiting period of 1 week, they were inserted on the left side in both groups; however, the order of laser application was changed. While the separator remained in place, the patient marked his degree of perceived discomfort on a Visual Analog Scale (VAS) at 5 minutes (T0), 24 hours (T1), and 120 hours (T2), after LLLT application.

Results:
A statistically significant difference was observed (P &lt; .005) in reducing discomfort in the exposed group compared with the placebo group. This reduction of discomfort in the EG was observed at all time intervals.

Conclusions:
A sincle AIGaAs diode LLLT application may be indicated for the control or reduction of pain in the early stages of orthodontic treatment.

Joseph Warren: a discussion of his life and analysis of his death
Authors: Holland Ryan , Sabourin Victor M. , Gandhi Chirag D. , Carmel Peter W. , Prestigiacomo Charles J. 
Published: July 2015

As his fellow soldiers ran past him, Joseph Warren stood bravely on Bunker Hill. It was June 17, 1775, and British troops were fighting the colonists in one of the early battles of the American Revolution. The British had already attempted two major assaults that day, and the third would end with Warren’s death. He was a medical doctor, public figure, and general who spent his life and last living moments fighting for freedom for the American colonists.
After the battle, there was much confusion about what had happened to Joseph Warren. Some thought he had survived the battle; other accounts differed on how exactly he had died. The details of the events on Bunker Hill remained a mystery until the following year, when Paul Revere helped identify Warren’s body by the false teeth that had been implanted years earlier. Warren’s remains showed that his head had been struck by a bullet.
Analysis of the skull helped to sift through the differing tales of Warren’s death and thus unveil the truth about what occurred that day. The smaller bullet wound in the left maxilla suggests that he was not shot while retreating with the rest of the soldiers. The larger exit wound in the right occiput illustrates that the bullet’s trajectory crossed the midline of the brain and most likely injured the brainstem. Therefore, contrary to rumors that circulated at the time, Joseph Warren most likely was killed instantly at the Battle of Bunker Hill while heroically facing his enemy.
Left temporal craniotomy for clipping of fusiform aneurysm of posterior cerebral artery
Authors: Malik Ghaus M. , Pabaney Aqueel H. 
Published: July 2015

Aneurysms of the posterior cerebral artery (PCA) are a distinct pathological entity and are surgically challenging. Fusiform aneurysms involving the PCA are quite rare and scarcely reported in the literature. In this video, we demonstrate the utility of the subtemporal approach to surgically reconstruct an unruptured, fusiform aneurysm of the left PCA, located at the junction of P3 and P4 segments. Curved clips were used to reconstruct the aneurysm such that flow was maintained in the parent vessel as well as distal branches. Postoperatively, the patient remained neurologically intact.The video can be found here: http://youtu.be/l7yzUPsaMc4.
Microsurgical treatment of recurrent coiled aneurysms
Authors: David Carlos A. 
Published: July 2015

The number of endovascularly-treated aneurysms has steadily increased over the past two decades. A small but significant number of recurrent or partially recanalized aneurysms have been identified. If repeat endovascular therapies are not feasible due to anatomical or technical considerations, surgical clipping may be considered. The technical challenges in the microsurgical treatment include coils interfering with the clip application; the possibility of an aneurysm that is less collapsible and less easy to manipulate; and intraluminal thrombus formation requiring thrombus and coil removal. The video presents the technical steps and nuances for clipping. The technical issues for coil removal are illustrated in two cases.The video can be found here: http://youtu.be/NvhSDVT4iuE.
Accountable wiretapping – or – I know they can hear you now

Published: July 2015

Abstract In many democratic countries, Communications Assistance for Law Enforcement Act (CALEA) wiretaps are used by law enforcement agencies to perform investigations and gather evidence for legal procedures. However, existing CALEA wiretap implementations are often engineered with the assumption that wiretap operators are trustworthy and wiretap targets do not attempt to evade the wiretap. Although it may be possible to construct more robust wiretap architectures by reengineering significant portions of the telecommunications infrastructure, such efforts are prohibitively costly. This paper instead proposes a lightweight accountable wiretapping system for enabling secure audits of existing CALEA wiretapping systems. Our proposed system maintains a tamper-evident encrypted log over wiretap events, enforces access controls over wiretap records, and enables privacy-preserving aggregate queries and compliance checks. We demonstrate using campus-wide telephone trace data from a large university that our approach provides efficient auditing functionalities while incurring only modest overhead. Based on publicly available wiretap reporting statistics, we conservatively estimate that our architecture can support tamper-evident logging for all of the United States’ ongoing CALEA wiretaps using three commodity PCs.
Practical and provably secure distance-bounding
Authors: Boureanu Ioana , Mitrokotsa Aikaterini , Vaudenay Serge 
Published: July 2015

Abstract From contactless payments to remote car unlocking, many applications are vulnerable to relay attacks. Distance bounding protocols are the main practical countermeasure against these attacks. In this paper, we present a formal analysis of SKI, which recently emerged as the first family of lightweight and provably secure distance bounding protocols. More precisely, we explicate a general formalism for distance-bounding protocols, which lead to this practical and provably secure class of protocols (and it could lead to others). We prove that SKI and its variants are provably secure, even under the real-life setting of noisy communications, against the main types of relay attacks: distance-fraud and generalised versions of mafia- and terrorist-fraud. To attain resistance to terrorist-fraud, we reinforce the idea of using secret sharing, combined with the new notion of a leakage scheme. In view of resistance to generalised mafia-frauds (and terrorist-frauds), we present the notion of circular-keying for pseudorandom functions (PRFs); this notion models the employment of a PRF, with possible linear reuse of the key. We also identify the need of PRF masking to fix common mistakes in existing security proofs/claims. Finally, we enhance our design to guarantee resistance to terrorist-fraud in the presence of noise.
Tanshinone IIA inactivates Akt and induces caspase-dependent death in cervical cancer cells via the mitochondrial pathway
Authors: Li Hu , Xu Yan , Yang Li , He Lei 
Published: July 2015

<p>In human cervical cancer cells pro-apoptotic effect of tanshinone IIA isolated from the ethanol extract of Scutellaria barbata was investigated. Tanshinone IIA treatment resulted in apoptosis and mitochondrial membrane potential loss in the cervical cancer cells. The viability of SW756 and C4-1 cells was reduced in a concentration dependent manner on treatment with tanshinone IIA for 36 hours. Flow cytometric analysis in SW756 cells showed marked increase in accumulation of sub-G1-phase cell population. Tanshinone IIA treatment also caused significant increase in DNA fragmentation in these cells. DAPI staining revealed significant increase in nuclear condensation and apoptotic body formation on tanshinone IIA treatment in SW756 cells However, the effect of tanshinone IIA was reversed by caspase inhibitor, z-VAD-fmk. In tanshinone IIA treated cells Akt phosphorylation was markedly reduced and this decrease was inhibited by LY294002 (phosphatidylinositol-3'-kinase inhibitor). Tanshinone IIA treated apoptotic cells exhibited decrease in expression of Mcl-1. Thus tanshinone IIA induces apoptosis in cervical cancer cells through mitochondrial pathway. </p><p> </p>

<p>Escopoletin, a phenolic compound belonging to anthocyanin family shows promising antioxidant activities. In the present study, anti-cancer effects of escopoletin treatment in DU145 cells were investigated. The sulphorhodamine-B staining and annexin V and propidium iodide were respectively used for the analysis of cell viability and death. The results revealed a significantly higher cytotoxicity by escopoletin that caused cell death in DU145 cells. Escopoletin treatment in DU145 cells markedly inhibited cell growth through non-apoptotic cell death and induced significant reactive oxygen species (ROS) production. It also induced G1 cell cycle arrest and cyclin D1 accumulation through the enhanced expression of p21. However, the effect of escopoletin on DU145 cells was reversed by pretreatment with glutathione antioxidant. This suggests that escopoletin induced generation of ROS is responsible for the increased cytotoxicity in DU145 cells. Thus, escopoletin exhibits potential therapeutic efficacy for the treatment of prostate cancer.</p><p> </p>

O artigo parte de um desvendamento etnográfico da(s) chamada(s) cracolândia(s) paulistana e carioca, com o intuito de lançar um olhar antropológico sobre determinadas dinâmicas relacionais e espaciais urbanas. Para tanto, detemo-nos sobre os modos como se constituem como territorialidades itinerantes, em São Paulo e no Rio de Janeiro. A comparação sugere que a “itinerância” mesma da(s) cracolândia(s) aponta o fato de como elas se produzem em espaços constituídos por outras territorialidades em disputa – em particular, no contexto de grandes intervenções urbanas que visam ressignificar certas regiões das cidades em questão – e ainda para como as rotinas e as disputas em torno da(s) cracolândia(s) geram uma série de conflitos para além daqueles relacionados à repressão policial, produzindo também conexões com outros espaços.
Mulher cuidadora, homem arredio: diferenças de gênero na promoção da saúde masculina

Jean Ballard, une figure du « travailleur intellectuel »
Authors: Brun-Franc Christel 
Published: July 2015

Les directeurs de revue sont presque toujours considérés comme des intellectuels. Pourtant, cette notion pose problème et les définitions s’opposent. En confrontant plusieurs d’entre elles, nous proposons de nous interroger sur le personnage de Jean Ballard, directeur de la revue marseillaise les Cahiers du Sud entre 1925 et 1966, au travers de trois des critères principaux qui semblent définir un intellectuel (l’absence d’intérêt pour les questions pratiques, l’engagement politique et une grande faculté de conceptualisation). Nous circonscrirons notre propos à la période de l’entre-deux-guerres. Devant l’impasse à laquelle nous aboutirons, plutôt que d’utiliser cette notion mouvante, nous préférerons revenir au concept d’« intellectualité » et de parler, en ce qui le concerne, de « travailleur intellectuel ».
Clinical Indicators for Endotracheal Suctioning in Adult Patients Receiving Mechanical Ventilation
Authors: Sole Mary Lou , Bennett Melody , Ashworth Suzanne 
Published: July 2015

Background
Critically ill patients who need mechanical ventilation require endotracheal suctioning. Guidelines recommend coarse crackles over the trachea and/or the presence of a sawtooth pattern on the flow-volume loop of the ventilator waveform as the best indicators.

Objective
To determine clinical cues for endotracheal suctioning in patients who require mechanical ventilation.

Methods
A descriptive study of 42 adult patients receiving mechanical ventilation. After baseline endotracheal suctioning with a closed-system device, patients were assessed hourly up to 4 hours for guideline-based cues for endotracheal suctioning and lung sounds were auscultated. Endotracheal suctioning was done when cues were detected or 4 hours after baseline suctioning. Secretions were collected, measured, and weighed.

Results
Most patients were male (62%) and white (93%). Mean age was 51 years, and mean duration of mechanical ventilation was 7.5 days. The median time to endotracheal suctioning was 2 hours, and a mean of 4.4 mL of secretions was removed. Three patients had no cues identified but had 1.0 mL or more of secretions. The most frequent cues were crackles over the trachea (88%), sawtooth waveform (33%), coughing (29%), and visible secretions (5%). Cues resolved and physiological parameters improved after suctioning. Coarse lung sounds did not improve.

Conclusions
Patients receiving mechanical ventilation should be routinely assessed for coarse crackles over the trachea, the most common indicator for endotracheal suctioning. Despite common practice, assessment of lung sounds to identify the need for suctioning is not supported.
Assessment of a Brief Handoff Skills Workshop for Incoming Interns: Do past Handoff Experiences Impact Training Outcomes?
Authors: Smith Christopher J. , Wadman Michael C. , Harrison Jeffrey , Beck Gary L. 
Published: July 2015

Background Patient care handoffs are a core professional activity that incoming interns are expected to perform without direct supervision upon starting residency, yet training in medical schools is inconsistent. Objective To implement a brief handoff communication workshop for incoming interns and determine whether learner-level determinants were associated with differences in training outcomes. Methods We conducted a one-hour interactive handoff skills workshop for all incoming interns at a Midwestern academic medical center. We performed paired pre/post-intervention assessments of participants' attitudes and ability to perform representative handoff skills. The results were analyzed in aggregate and based upon participants' prior handoff experiences using Wilcoxon signed-rank test. Results Ninety-nine of 108 interns (91.7%) completed both pre- and post-surveys. There was significant improvement in all 10 attitude-based questions ( P ≤ 0.014 for all) and on the skills assessment (1.07 vs 2.16 on 0–4 point scale, SD 1.25, P ≤ 0.001). Results remained significant regardless of prior training, number of handoffs observed, number of handoffs performed, medical school, or residency discipline. Conclusion A brief interactive workshop for incoming interns can improve participants' confidence and performance of basic handoff skills, regardless of previous training or experience.
Analysis of an Implicit Fully Discrete Local Discontinuous Galerkin Method for the Time-Fractional Kdv Equation
Authors: Wei Leilei , He Yinnian , Zhang Xindong 
Published: July 2015

AbstractIn this paper, we consider a fully discrete local discontinuous Galerkin (LDG) finite element method for a time-fractional Korteweg-de Vries (KdV) equation. The method is based on a finite difference scheme in time and local discontinuous Galerkin methods in space. We show that our scheme is unconditionally stable and convergent through analysis. Numerical examples are shown to illustrate the efficiency and accuracy of our scheme.
Thermoelectric Viscoelastic Fluid with Fractional Integral and Derivative Heat Transfer
Authors: Ezzat Magdy A. , Sabbah A. S. , El-Bary A. A. , Ezzat S. M. 
Published: July 2015

AbstractA new mathematical model of magnetohydrodynamic (MHD) theory has been constructed in the context of a new consideration of heat conduction with a time-fractional derivative of order 0 < α ≤ 1 and a time-fractional integral of order 0 < γ ≤ 2. This model is applied to one-dimensional problems for a thermoelectric viscoelastic fluid flow in the absence or presence of heat sources. Laplace transforms and state-space techniques will be used to obtain the general solution for any set of boundary conditions. According to the numerical results and its graphs, conclusion about the new theory has been constructed. Some comparisons have been shown in figures to estimate the effects of the fractional order parameters on all the studied fields.
Local RBFs Based Collocation Methods for Unsteady Navier-Stokes Equations
Authors: Zhang Xueying , An Xin , Chen C. S. 
Published: July 2015

AbstractThe local RBFs based collocation methods (LRBFCM) is presented to solve two-dimensional incompressible Navier-Stokes equations. In avoiding the ill-conditioned problem, the weight coefficients of linear combination with respect to the function values and its derivatives can be obtained by solving low-order linear systems within local supporting domain. Then, we reformulate local matrix in the global and sparse matrix. The obtained large sparse linear systems can be directly solved instead of using more complicated iterative method. The numerical experiments have shown that the developed LRBFCM is suitable for solving the incompressible Navier-Stokes equations with high accuracy and efficiency.

Published: July 2015

AbstractIn this paper, an optimal bicubic finite volume method is established and analyzed for elliptic equations on quadrilateral meshes. Base on the so-called elementwise stiffness matrix analysis technique, we proceed the stability analysis. It is proved that the new scheme has optimal convergence rate in H1 norm. Additionally, we apply this analysis technique to bilinear finite volume method. Finally, numerical examples are provided to confirm the theoretical analysis of bicubic finite volume method.
