Anxiety Sensitivity as a Predictor of Epilepsy-Related Quality of Life and Illness Severity Among Adult Epilepsy

The purpose of the current study was to examine the role of anxiety sensitivity in predicting seizure likelihood and QOL among 49 people with epilepsy (PWE; 63.3% female; Mage = 48.53, SD = 15.91). As hypothesized, after controlling for the effects of negative affectivity and past year seizure presence, greater levels of anxiety sensitivity significantly predicted poorer overall QOL as well as the QOL domains of seizure worry, medication effects, work-driving-social limitations, and cognitive functioning (8.8–22.9% unique variance). Anxiety sensitivity did not significantly predict seizure likelihood or QOL related to emotional well-being and energy difficulties. These findings suggest that PWE who are fearful of arousal-related sensations experience greater functional impairment, but not necessarily more severe epilepsy. Interventions aimed at decreasing anxiety sensitivity may be useful in improving QOL in this population.

Informal Caregiver Burden, Benefits, and Older Adult Mortality: A Survival Analysis.

OBJECTIVE Informal caregivers are crucial to maintaining older adults' health, but few studies examine how caregiving receipt is associated with older person longevity. In a nationally representative sample, we prospectively explore whether and how having an informal caregiver is associated with older adult overall mortality, and how caregivers' burden and benefits perceptions relate to care recipient mortality. METHODS We match six National Health and Aging Trends Study waves (2011-2016) with 2011 National Study of Caregiving data, conducting survival analysis on 7,369 older adults and 1,327 older adult-informal caregiver dyads. RESULTS Having an informal caregiver is associated with 36% (p < .001) higher mortality risk over 6-year follow-up, adjusting for demographic, economic, and health factors. Older adults whose caregivers perceive only burden have 38% higher (p < .05) mortality risk than those with caregivers reporting neither burden nor benefits. This risk is reduced from 38% higher to 5% higher (p < .001) for older adults with caregivers reporting benefits alongside burden, compared to those with caregivers reporting neither perception. DISCUSSION Having a caregiver may signal impending decline beyond known mortality factors. However, interventions to increase caregivers' benefit perceptions and reduce their burden may decrease mortality risk for older adults with declining health and functional ability.
How May Tribunals Apply the Customary Necessity Rule to the Argentine Cases? An Analysis of ICSID Decisions with Respect to the Interaction between Article XI of the U.S.-Argentina BIT and the Customary Rule of Necessity

Why have the nine ICSID decisions arising under the U.S.-Argentina BIT been inconsistent in the face of largely undisputed facts and identical legal norms? This article suggests that the disparate opinions in the Argentine cases may be a consequence of the lack of agreement on interpretive parameters that may guide an arbitration tribunal’s reasoning when faced with a rule of customary international law that is applicable to an investment dispute under a BIT. Specifically, the inconsistency seems to have emerged as tribunals have failed to agree on the principles that would allow them to deal with the interaction of Article XI of the US-Argentina BIT and the rule of necessity under customary international law. Drawing from Art. 31(3)(c) of the Vienna Convention on the Law of Treaties as dealt with in the International Law Commission’s Report and Conclusions on the Fragmentation of International Law, this article suggests a set of interpretive parameters that may serve future tribunals dealing with this same issue. The article concludes that a “harmonized fall-back” solution for the application of Art. XI in interaction with the customary rule of necessity may be more desirable from the perspective of international law, to the extent that tribunals wish to avoid conflict, instead conveying adherence to the principles of systemic integration, harmonization and the strong presumption against conflict.
Bone Matrix IGF-1 in Bone Remodeling

Abstract In bone remodeling, bone resorption and formation are coupled to ensure that the same amount of bone that is resorbed is replaced. Insulin-like growth factor type 1 (IGF-1) is a critical factor involved in coupled bone remodeling. IGF-1 is a unique peptide that can mediate endocrine, paracrine, and autocrine effects. IGF-1 is most often bound to proteins which aid in tissue-specific targeting, including deposition into the bone matrix. Bone matrix IGF-1 can act in a delayed paracrine manner to stimulate osteoblast and osteocyte differentiation, aiding in bone formation. IGF-1 interacts with multiple factors in the bone marrow microenvironment to regulate the bone remodeling process.
Lines of Play: Using Vector Tools to Place Game Objects in Augmented Reality

'Lines of Play' is a domino art application showcasing recent advancements in augmented reality (AR) technology. Unlike previous mobile AR applications that were limited to horizontal and vertical object placement, these game objects interact with real objects in the player's environment with surface-level resolution. Features of the player's environment provide kinematic constraints (on collision) and serve as obstructions both visually (occlusion) and during gameplay. Using single camera depth information, players can use familiar vector drawing tools to rapidly create and modify lines, rings, paths, and turns of domino tiles. We thereby provide a method for placing a plurality of gaming objects by converting raycasted anchor points into paths of game objects. This opens up novel possibilities of authoring tools specially adapted for AR game development or game-integrated level editing.
A Global Survey of EUV Coronal Power Spectra

We present results of an investigation of single-pixel intensity power spectra from a 12-hour time period on 26 June 2013 in a $1600 \times 1600$ -pixel region from four wavelength channels of NASA’s Solar Dynamics Observatory/Atmospheric Imaging Assembly. We extract single-pixel time series from derotated image sequences, fit two models as a function of frequency $[\nu]$ to their computed power spectra, and study the spatial dependence of the model parameters: i) a three-parameter power law + tail, $A\nu^{-n}+C$ , and ii) a power law + tail + three-parameter localized Lorentzian, $A\nu^{-n} + C + \alpha/ (1 + (\ln\nu-\beta)^{2} /\delta^{2} )$ , the latter to model periodicity. Spectra are well described by at least one of these models for all pixel locations, with the spatial distribution of best-fit model parameters shown to provide new and unique insights into turbulent, quiescent, and periodic features in the EUV corona and upper photosphere. Findings include the following: individual model parameters correspond clearly and directly to visible solar features; detection of numerous quasi-periodic three- and five-minute oscillations; observational identification of concentrated magnetic flux as regions of largest power-law indices $[n]$ ; identification of sporadically located five-minute oscillations throughout the corona; detection of the known global ${\approx}\,\mbox{four}$ -minute chromospheric oscillation; 2D spatial mapping of “coronal bullseyes” appearing as radially decaying periodicities over sunspots and sporadic foot-point regions, and of “penumbral periodic voids” appearing as broad rings around sunspots in 1600 and 1700 A in which spectra contain no statistically significant periodic component.
The SCREAM Concept for the Next-Generation Very Large Array Central Signal Processor

The Next-Generation Very Large Array (ngVLA) is a future radio astronomy facility, building on the existing Very Large Array in New Mexico, which promises an order of magnitude improvement over current capabilities in terms of sensitivity, angular and spectral resolutions. With 263 antennas up to thousands of miles away, each one generating almost a terabit-per-second of data to be processed in real time, the design of a Central Signal Processor for the ngVLA project appears as a formidable technical challenge. We propose the SCalable, REconfigurable And Modular (SCREAM) design concept based on highly optimized building blocks that connect to each other to form the system, thus enabling economies of scale while minimizing hardware cost, size, and power. Functional flexibility is obtained through block reconfigurability. Its scalable architecture makes the SCREAM design a suitable candidate not only for the ngVLA, but also for any potential future interferometer facilities.
Spread Spectrum Techniques with Channel Coding for Wideband Secured Communication Links

Ultra-wideband (UWB) radios provide avenues for interference immunity using spread spectrum (SS) techniques. Doing so, provides a processing gain of 21 dB, allowing for successful retrieval of signals propagated below the noise floor. In addition, by applying advanced channel coding an additional coding gain of 9 dB can be achieved. In this paper, we are exploiting SS techniques with channel coding to maximize gain in wireless communication links. Bit error rate (BER) performance is presented for multiple channel coding approaches.
Heading errors in all-optical alkali-metal-vapor magnetometers in geomagnetic fields

Using an Outsourced Online Tutoring Service to Promote Success in Online Composition Courses

For some students enrolled in online courses, receiving tutoring may be a key component to their success. This study sought to determine if the use of an outsourced online tutoring service (OOTS) was associated with course success in online English Composition courses. The authors employed chi-square tests to analyze the relationship between tutoring usage and final grades for students in two different composition courses, English Composition I (n = 888) and English Composition II (n = 1108). The results indicate that in both courses, students who utilized the OOTS passed the course at higher rates than those who did not. For students who utilized the service at least once, 95% passed English Composition I, compared with a 57% passing rate of students who did not utilize the service. Results for English Composition II were similar with 89% of OOTS users passing the course, compared with a 58% passing rate of non-users. This research supports and discusses the importance of online tutoring for students.
Late Presentation of Seizures in a 54 year old male with Sturge Weber Syndrome (329)

Objective: Case report of first seizure at the age of 54 years in an adult male with Sturge Weber Syndrome. Background: Sturge Weber Syndrome is a congenital disorder characterized by facial capillary malformations and capillary-venous malformations affecting the brain and eye. The capillary-venous malformations can occur in the leptomeninges, choroid, or conjunctiva, creating an epileptogenic focus, glaucoma, hemiparesis or visual field defects. We report a patient who, at the age of 54, presented with headache, right sided visual field deficit, progressive encephalopathy and ultimately new-onset seizures. His past medical history was significant for hypothyroidism and glaucoma OS. Physical exam revealed a violaceous rash over the left eyelid and forehead. Neurologic exam showed no focal deficits. MRI Brain with and without contrast revealed abnormal T2/FLAIR hyperintensity in the left parietal, temporal and occipital lobes along with the leptomeninges in the same region. The left choroid plexus avidly enhanced and there was left hemiatrophy. The patient was diagnosed with Sturge-Weber Syndrome from the clinical features and characteristic MRI findings. If present, seizures typically present within the first 5 years of life in patients with Sturge Weber Syndrome. However, this patient presented at the age of 54. These cases are atypical and often misdiagnosed as hemiplegic migraine. Design/Methods: NA Results: NA Conclusions: This patient is one of the oldest reported with new-onset seizures as the first manifestation of Sturge-Weber Syndrome. Violaceous facial rashes and seizures should always bring Sturge-Weber Syndrome into the differential diagnosis. Co-morbid seizures may occasionally present late in life and due to their potential origination from the occipital lobes, may present with features similar to migraine headache with visual aura.

The effects of shoulder arthroscopy on ultrasound image quality of the interscalene brachial plexus: a pre-procedure vs post-procedure comparative study.

Fluid extravasation from the shoulder compartment and subsequent absorption into adjacent soft tissue is a well-documented phenomenon in arthroscopic shoulder surgery. We aimed to determine if a qualitative difference in ultrasound imaging of the interscalene brachial plexus exists in relation to the timing of performing an interscalene nerve block (preoperative or postoperative). This single-center, prospective observational study compared pre- and postoperative interscalene brachial plexus ultrasound images of 29 patients undergoing shoulder arthroscopy using a pretest-posttest methodology where individual patients served as their own controls. Three fellowship-trained regional anesthesiologists evaluated image quality and confidence in performing a block for each ultrasound scan using a five-point Likert scale. The association of image quality with age, gender, BMI, duration of surgery, obstructive sleep apnea, and volume of arthroscopic irrigation fluid were analyzed as secondary outcomes. Aggregate preoperative mean scores in quality of ultrasound visualization were higher than postoperative scores (preoperative 4.5 vs postoperative 3.8; p < .001), as was confidence in performing blockade based upon the imaging (preoperative 4.8 vs postoperative 4.2; p < .001). Larger BMI negatively affected visualization of the brachial plexus in the preoperative period (p < 0.05 for both weight categories). Patients with intermediate-high risk or confirmed obstructive sleep apnea had lower aggregate postoperative mean scores compared to the low-risk group for both ultrasound visualization (3.4 vs 4.0; p < .05) and confidence in block performance (3.8 vs 4.4; p < .05). Due to the potential reduction of ultrasound visualization of the interscalene brachial plexus after shoulder arthroscopy, we advocate for a preoperative interscalene nerve block when feasible.

Validation of Methods for Estimation of Knee Joint Mechanical Impedance During Locomotion Using a Torque-Controllable Knee Exoskeleton.

The mechanical impedance of the joints of the leg govern the body's response to external disturbances, and its regulation is essential for the completion of tasks of daily life. However, it is still unclear how this quantity is regulated at the knee during dynamic tasks. In this work, we introduce a method to estimate the mechanical impedance of spring-mass systems using a torque-controllable exoskeleton with the intention of extending these methods to characterize the mechanical impedance of the human knee during locomotion. We characterize system bandwidth and intrinsic impedance, and present a perturbation-based methodology to identify the mechanical impedance of known spring-mass systems. Our approach was able to obtain accurate estimates of stiffness and inertia, with errors under 3% and ~13-16%, respectively. This work provides a qualitative and quantitative foundation that will enable accurate estimates of knee joint impedance during locomotion in future works.

Refusing to Tolerate Intolerance: An Experiment Testing the Link Between Exposure to Gay-Related Content and Resulting Attitudes and Behaviors

This article describes a 2 × 2 factorial design experiment with 334 undergraduates testing the influence of exposure to gay-related photographs on endorsement of tolerant gay attitudes and likelihood to interact with the photograph within a social media context. Individuals were more likely to interact with and be attitudinally influenced by pro-gay rather than anti-gay content. Prior media exposure to gay-related content was positively associated with likelihood to interact with the photographs. The experimental condition moderated this association. Our results provide support and extension for social cognitive theory, cultivation, and the heuristic processing model, as well as offer new information related to the study of social media, particularly those current conversational trends related to gay men and lesbians.
The quality of interactive computer use among HIV-infected individuals.

This study examined how HIV-infected individuals used an interactive health software package called CHESS (Comprehensive Health Enhancement Support System). CHESS packages information and support in a variety of ways ; the research examined how a subset of users whose posttest scores in a larger randomized trial showed significant improvement in quality of life compared on use patterns of CHESS with those who did not improve. The evidence presented here points to the nature of CHESS use more than it does to the amount of CHESS use. Those whose quality of life improved were among the most involved in their use of CHESS information tools. That is, even though Discussion Group accounted for the majority of all CHESS uses and time spent with the system, total use and Discussion Group use appeared less important than use of the information tools, especially if that use was at least somewhat sustained and involved.
High current proton beams in multi-stage linear induction accelerators

A 1-MV, 6-kA, 50-ns annular proton beam has been generated in a full-cusp-geometry diode and transported along a 0.6-T solenoidal magnetic field. The radial profile and transport efficiency were measured under different drift tube conditions using carbon activation. Faraday cup arrays gave time-resolved measurements of the net and ion current densities. The measurements showed that successful transport can be achieved by using a fast puff valve to fill the drift region immediately downstream of the full cusp with neutral gas. The exact neutralization process is still being studied, but it is thought that the plasma created from the neutral gas allows electrons to be pulled from the drift tube walls, neutralizing the space charge of the ion beam. Results have demonstrated beam transport efficiencies of 99% and maintenance of the annular beam profile throughout the drift region. The results have implications for the development of multistage induction accelerators. >

The Paradoxes of Global Economic Convergence

The global economy of the past century was dominated by the United States and Western Europe. When they sneezed, the old joke goes, the rest of the world caught a cold. But that dominance is now being challenged by the rise of rapidly growing emerging market economies. And the shift is changing the dynamics of trade and capital flows in profound ways. Here, I outline the consequences of this evolving world economic order – in particular, how it is decoupling the business cycles of the economies of the North and South while simultaneously tightening other bonds between them that must be managed well to ensure prosperity.
Applicability of a Measurement System: Sensor Response and Representativeness

A complete view of the management (acquiring and use) of meteorological data requires the consideration of many factors, from the dynamic response characteristics of the sensor to the time and spatial representiveness of the final numerical quantity produced. The mathematical techniques for quantifying the various factors associated with a particular measurement are well developed. This paper reviews some fundamentals of the response and errors of typical meteorological sensors, with an emphasis on the sort of responses and errors that arise when the instrument is used in the real turbulent atmosphere, and also reviews factors of averaging and representativeness. Broader aspects of representativeness are also discussed from the perspective of incorporating the measurements into complete atmospheric descriptions or models.
Interdiffusion and intrinsic diffusion in binary vanadium-titanium solid solutions at 1350°C

Interdiffusion coefficients, intrinsic diffusion coefficients, and vacancy wind parameters have been determined in the vanadium-titanium system at 1350°C with the use of infinite, solid-solid diffusion couples. The experimentally determined diffusion coefficients were compared with the values predicted from the models of Darken, Manning and Dayananda with the use of available tracer diffusion and thermodynamic information and were found to be larger than those calculated from the three models. Vacancy wind parameters, determined experimentally, were seen to reflect a greater influence of the vacancy wind phenomenon on the intrinsic diffusion flux of each species than that calculated on the basis of Manning’s theory. In particular, the faster diffusing component is enhanced and the slower diffusing component is retarded to a greater degree than is theoretically predicted. Furthermore, experimental and predicted values of intrinsic diffusivity ratios,D V /D Ti ,were compared and the results suggest an increased effect of vacancy flow on the intrinsic fluxes with respect to the magnitude of this phenomenon calculated from Manning’s treatment. The vacancy wind effect is shown to be an important factor in the consideration of intrinsic diffusion fluxes and their relation to tracer diffusion and thermodynamic information in the vanadium-titanium system.
Nontypeable Haemophilus influenzae susceptibility: Effect of inoculum size and β-lactamase production

The activities of cefixime, cefpodoxime, cefprozil, cefuroxime, loracarbef, and amoxicillin/clavulanate against 72 clinical isolates of nontypeable Haemophilus influenzae were determined by using an agar dilution method. The effects of β-lactamase production and bacterial inoculum size were investigated. All antimicrobials exhibited a significant inoculum effect, demonstrating the importance of accurately determining inoculum size in the performance of antimicrobial susceptibility testing of H. influenzae.
Timing and magnitude of serum creatine kinase-MB after transcatheter cardiac tissue fulguration in man.

Abstract This study examined the impact of transcatheter fulguration on creatine kinase-MB release in 21 patients (age range 17–71 years). Arrhythmia diagnoses were ventricular tachycardia 9, atrial fibrillation with a rapid ventricular response 7, atrioventricular nodal reentry 2, and reciprocating tachycardia utilizing a posteroseptal accessory pathway 3. Seven patients had apparently normal hearts while 8 had ischemic heart disease and 6 cardiomyopathy. Timing of initial elevated creatine kinase-MB activity (mean 1.34 ± 0.69 SD hours) and peak creatine kinase-MB activity (mean 3.73 ± 0.89 SD hours) was relatively uniform in all patients. Time to peak creatine kinase-MB activity was unrelated to either underlying cardiac disease (normal: 3.9 ± 1.0 hours; ischemic heart disease: 3.5 ± 0.9 hours; cardiomyopathy: 3.8 ± 0.9 hours), or fulguration site (His bundle ( n = 9): 4.2 ± 0.9 hours, proximal coronary sinus ( n = 3): 3.3 ± 0.3 hours, ventricle ( n = 9): 3.4 ± 0.8 hours). The magnitude of peak serum creatine kinase-MB activity was independent of myocardial diagnosis or fulguration site, but was linearly related to total energy delivered ( r = 0.5, P r = 0.92, P P r = 0.57, P = NS). Thus, serum creatine kinase-MB activity following transcatheter fulguration is linearly related to the magnitude of delivered energy, and is similar to that observed after transient coronary artery occlusion and reperfusion.
Regulatory elements for the tissue-specific expression of the rat serine dehydratase-encoding gene.

Abstract l -Serine dehydratase (SDH; EC 4.2.1.13), the key enzyme for serine utilization in the rat, is synthesized primarily in the liver. Cis-acting DNA elements required for liver-specific expression of the SDH gene were identified by two approaches: (7) transient expression assays in primary cultured rat hepatocytes, and in rat fibrosarcoma and normal rat kidney epithelial (NRK-52E) cell lines; and (2) in vitro transcription assays with nuclear extracts prepared from rat liver and spleen. Deletion analyses of the 5' flanking sequences of the gene have defined two functionally different regions: (a) a cell-type-specific promoter located between positions -62 and + 10, which is sufficient for liver-specific expression; and (b) a distal promoter region between bp −133 and −63 containing positive cu-acting elements that regulate the promoter activity in a non-tissue-specific fashion. No other cis-acting elements essential for liver-specific expression were found in the region of −134 to 2.1 kb upstream relative to the cap site of SDH.
Autonomous phase retrieval control for calibration of the Palomar Adaptive Optics system

An autonomous wavefront sensing and control software suite (APRC) has been developed as a method to calibrate the internal static errors in the Palomar Adaptive Optics system. An image-based wavefront sensing algorithm, Adaptive Modified Gerchberg-Saxton Phase Retrieval (MGS), provides wavefront error knowledge upon which actuator command voltages are calculated for iterative wavefront control corrections. This automated, precise calibration eliminates non-common path error to significantly reduce AO system internal error to the controllable limit of existing hardware, or can be commanded to prescribed polynomials to facilitate high contrast astronomy. System diagnostics may be performed through analysis of the wavefront result generated by the phase retrieval software.

Textured fluorine-doped ZnO films by atmospheric pressure chemical vapor deposition and their use in amorphous silicon solar cells

Abstract Fluorine-doped ZnO films were deposited on soda lime glass by atmospheric pressure chemical vapor deposition at temperatures from 350 to 470 °C by using diethyl zinc, ethanol and hexafluoropropene as precursors. The deposited films typically contained about 0.1 to about 1.0 at.% fluorine with conductivities up to 2500 ω−1 cm−1. The free electron concentrations determined from Hall coefficient measurements were up to 5 × 10 20 cm −3 and the mobilities were between 10 and 40 cm2 V−1 s−1. The films with very low sheet resistances of 5 ω/□ were found to have visible absorption of only 3% and transmittance up to 90% in the visible and reflectance of about 85% in the infrared. The film roughness was controlled by the deposition temperature and by introducing a small amount of water vapor. The rough films were used as substrates for amorphous silicon solar cells with very high quantum efficiency (up to 90%).

Spectrophotometric Determination of Acid Hydrazides via Nickel (II)-Catalyzed Hydroxamic Acid Formation

The reaction of phenyl acetate with hydroxylamine to form acetohydroxamic acid is catalyzed by nickel (II). Kinetic studies revealed that of the two steps in this process (the first being formation of O-acetylhydroxylamine and the second its conversion to acetohydroxamic acid), it is the second step that is catalyzed by nickel (II). Formation of a five-membered chelate ring between nickel (II) and O-acetylhydroxylamine was postulated to account for the catalysis. This hypothesis suggested that acid hydrazides, which are structurally similar to O-acylhydroxylamines, should also undergo hydroxylaminolysis catalyzed by nickel (II). This predicted catalysis was observed with four acid hydrazides. A spectrophotometric method for acid hydrazides was developed based upon their nickel (II)-catalyzed conversion to hydroxamic acids, followed by treatment with ferric ion to give the colored ferric hydroxamate complex. Isonicotinic acid hydrazide can be determined in the 10−4-10−2 M concentration range in aqueous solutions without interference from isonicotinic acid.
The interaction of Hoechst 33258 with natural and biosynthetic nucleic acids.

Abstract The bihelical polydeoxyribonucleotides DNA and poly (deoxyadenylate-deoxythymidylate form at least two distinct complexes with the dye Hoechst 33258. The nonfluorescent complex formed at low polymer/dye ratios is replaced at high polymer/dye ratios by an intensely fluorescent complex. The transition is accompanied by pronounced changes in circular dichroism and absorption spectra and may be interpreted in terms of a noncooperative replacement of dye molecules bound in proximity by isolated molecules of bound dye. In the case of the bihelical polyribonucleotides the transition exhibits positive cooperativity and major differences from the deoxyribose polymers exist in the circular dichroism spectra, suggesting a different geometry for the complex species.
Program reflections on the role of longitudinal digital portfolios in the development of technology competence

Abstract Digital portfolios in teacher education provide opportunities to conceptualize learning and growth over time. The digital portfolio experiences of two secondary teacher education students in the context of an entire preservice teaching experience are presented. These vignettes, along with programmatic observations from the past four years, indicate that high‐level uses of educational technology are difficult to facilitate in large teacher education programs using a technology infusion model that emphasizes general skills. Whereas many teacher education programs have abandoned required technology courses to jump start National Educational Technology Standards‐based competence, the authors argue that advanced courses in educational technology for teacher education majors are still necessary for curricular integration with technology. This article concludes with a discussion of the nature and level of technology competence in relation to portfolio development and makes recommendations for how progra...

A rapid protein folding assay for the bacterial periplasm.

An array of genetic screens and selections has been developed for reporting protein folding and solubility in the cytoplasm of living cells. However, there are currently no analogous folding assays for the bacterial periplasm, despite the significance of this compartment for the expression of recombinant proteins, especially those requiring important posttranslational modifications (e.g., disulfide bond formation). Here, we describe an engineered genetic selection for monitoring protein folding in the periplasmic compartment of Escherichia coli cells. In this approach, target proteins are sandwiched between an N-terminal signal recognition particle (SRP)-dependent signal peptide and a C-terminal selectable marker, TEM-1 β-lactamase. The resulting chimeras are localized to the periplasmic space via the cotranslational SRP pathway. Using a panel of native and heterologous proteins, we demonstrate that the folding efficiency of various target proteins correlates directly with in vivo β-lactamase activity and thus resistance to ampicillin. We also show that this reporter is useful for the discovery of extrinsic periplasmic factors (e.g., chaperones) that affect protein folding and for obtaining folding-enhanced proteins via directed evolution. Collectively, these data demonstrate that our periplasmic folding reporter is a powerful tool for screening and engineering protein folding in a manner that does not require any structural or functional information about the target protein.

The Pathophysiology, Diagnosis and Treatment of Fibromyalgia

Research in fibromyalgia has increased understanding of the possible genetic and environmental factors that could be involved in the etiology of fibromyalgia. There is now substantial evidence for augmentation of central pain processing in fibromyalgia. Because the clinical presentation of fibromyalgia is heterogeneous, treatment recommendations must be individualized for each patient. The rapid growth of trials in fibromyalgia in recent years has resulted in new evidence-based approaches to pharmacological and nonpharmacological treatment.
Exercise provocable right ventricular outflow tract tachycardia.

Abstract During the past 5 years, we have seen six patients who met inclusion criteria of exertional palpitations, reproducible treadmill (TM) provocable ventricular tachycardia (VT), and performance of electrophysiologic (EP) studies including isoproterenol (ISO) infusion. There were five males and one female, aged 15 to 55 years (mean ± SD, 31 ± 18 years). Three patients were trained athletes, two patients had mitral valve prolapse, three had enlarged right ventricular (RV) volumes (all trained athletes), and two had no evidence of organic heart disease. TM testing in all patients demonstrated reproducible exercise-provocable VT of at least 20 beats' duration. TM VT was characterized by left bundle branch block pattern QRS morphology and rates of 150 to 230 bpm (186 ± 30 bpm). Ep did not reproduce VT in five of six patients while ISO at a dose of 2 to 4 μg/min (2.5 ± 0.8 μg/min) reproduced VT in all patients. ISO VT was characterized by QRS morphology identical to TM VT and rates of 165 to 230 bpm (191 ± 26 bpm). Endocardial mapping of ISO VT revealed earliest activity in RV outflow tract. Serial TM testing revealed suppression of TM VT in all six patients on propranolol therapy. Responses to class I drugs were variable and less successful. In summary, we describe a group of patients with common clinical, ECG, and electrophysiologic features who may share a common pathophysiology of VT. Possible mechanisms are discussed.
Structure and transition of eutectic (Mg,Al)2Ca Laves phase in a die-cast Mg–Al–Ca base alloy

Abstract The crystal structure of a eutectic (Mg,Al)2Ca Laves phase in as-cast AXJ530 (Mg–5Al–3Ca–0.15Sr) was identified as C36 by electron diffraction analysis. The C36 phase transformed to C15(Al2Ca) during annealing at 573 K. The orientation relationship for the C15 and C36 phases is reported.
Cytokine production in patients with anorexia nervosa, bulimia nervosa, and obesity.

Objective We previously reported elevated serum levels of the cytokines interleukin-6 (IL-6) and transforming growth factor-β (TGF-β) in patients with anorexia nervosa (AN). We investigated the cellular production of these two cytokines and of interferon-γ (IFN-γ), interleukin-1α (IL-1α), and tumor necrosis factor-α (TNF-α) in subjects with AN, bulimia nervosa (BN), and obesity as well as in normal-weight control subjects. Methods Supernatant fluids from isolated peripheral blood mononuclear cells (PBMC) incubated with and without concanavalin A (ConA) were assayed for cytokine concentrations by enzyme-linked immunosorbent assay (ELISA). Results Significant differences across the four groups were found in the stimulated cellular production of IFN-γ and IL-6. Stimulated IFN-γ production was elevated in the AN group compared to controls. IL-6 production was significantly elevated in obese subjects relative to the two normal-weight groups, BN and controls, and tended to be higher in the AN group than in the controls, but not significantly so. IL-1α production was greater in obese subjects. Conclusion The findings of increased IFN-γ production and a tendency toward increased IL-6 production (both of which suppress food intake in animals) in individuals who severely restrict food intake suggest a potential role for these cytokines in the pathogenesis of AN. Elevated IL-6 and IL-1α production by PBMC in obese individuals requires further investigation to determine if these cytokines contribute to the development or perpetuation of obesity. © 2000 by John Wiley & Sons, Inc.

SPIRITUAL CAPITAL AND THE “GOOD LIFE”

The association among values, norms, roles and social structures is one of the major cornerstones of sociology. Since the publication of Bellah and company's Habits of the Heart (1996), more attention has been directed toward moral sociology while Putnam's Bowling Alone (2000) has stimulated discussions about social networks and social capital. This article meshes these areas while adding spiritual capital to the mix. This study draws heavily upon the classical work of W.E.B. Du Bois (Du Bois and Dill 1914) on morals, manners, and social uplift, the more contemporary work of Stark (2004) and Greeley (1989) on the perception of the supernatural and social behavior as well as Brewer's (1979) and Koenig's (1997 2002 2005) work on spiritual well-being and everyday life.
Clinical and Chest Radiographic Findings Among Persons With Sputum Culture Positive for Mycobacterium gordonae: A Review of 19 Cases

Study objectives To describe the clinical andradiographic findings associated with growth of Mycobacteriumgordonae in cultured sputum and to determine the proportion ofcases that fulfill criteria for nontuberculous mycobacterial pulmonarydisease as established by the American Thoracic Society. Design A retrospective review of charts and radiographs ofall patients from whom M gordonae was isolated fromsputum cultures between November 1996 and June 1998. Setting University-affiliated Veterans Affairshospital. Patients Nineteen patients were identifiedwith sputum culture positive for M gordonae . Allpatients had a chest radiograph within 1 month of sputum culture. Results Sixteen patients (84%) had suppressed localand/or general immunity. Sixteen patients (84%) had respiratorysymptoms, weight loss, fever, or night sweats as an indication forchest radiography. Seventeen patients (89%) had abnormal chestradiographs; however, no typical radiographic pattern was observed. Nopatient met diagnostic criteria for nontuberculous mycobacterialpulmonary disease as delineated by the American Thoracic Society. Allpatients with abnormal chest radiographs and/or respiratory symptomsultimately had alternative explanations for their pulmonarydisease. Conclusions There is a broad spectrum ofchest radiographic findings among persons with sputum culture positivefor M gordonae , arguing against the presence of acharacteristic chest radiograph in this patient population. Mgordonae is usually a nonpathogenic colonizing organism, evenamong persons with local or general immune suppression and abnormalchest radiograph findings.
Dissecting the Chain Length Specificity in Bacterial Aromatic Polyketide Synthases using Chimeric Genes

Abstract Many aromatic polyketides are synthesized by bacterial enzyme complexes called polyketide synthases (PKSs). Previous work has indicated that two subunits in the PKS, called the ketosynthase (KS) and chain length factor (CLF), play a central role in determining the chain length of the polyketide product. The purpose of this study was to construct and analyze chimeric KS and CLF proteins in order to identify the structural determinants of chain length. The genes encoding KS and CLF subunits from different aromatic PKSs share significant (50–70%) sequence identity. This similarity provides a means to genetically engineer the PKSs by directed gene shuffling methods. A set of hybrid KS and CLF genes were designed based on the sequences of the actinorhodin (a 16 carbon polyketide) and tetracenomycin (a 20 carbon polyketide) PKS genes. Analysis of these chimeric genes ruled out a role for most of the KS and reinforced the importance of the CLF in controlling polyketide chain length. Homology modeling of the quaternary structures of the functional hybrid KS–CLF dimers based on recent crystal structures of the ketosynthase homodimer from E. coli suggested that the regions of the KS and CLF that are most important for activity and specificity are located at the interface of this dimer.
Medication adherence challenges among HIV positive substance abusers: the role of food and housing insecurity.

This study examines the prevalence of food/housing insecurity and its association with psychological, behavioral, and environmental factors impacting antiretroviral (ARV) medication adherence and diversion among substance using HIV+ patients in South Florida. Five hundred and three HIV+ substance abusers were recruited through targeted sampling. Participants completed a standardized instrument assessing demographics, mental health status, sex risk behaviors, HIV diagnosis, treatment history and access, ARV adherence and diversion, and attitudes toward health-care providers. Chi-square and t-tests were used to examine differences by food/housing status and a multivariate linear regression model examined food/housing insecurity and its associations to ARV adherence. Food/housing insecurity was reported by 43.3% of the sample and was associated with higher likelihood of severe psychological distress and substance dependence. Nearly 60% reported recent ARV diversion; only 47.2% achieved 95% medication adheren...
