After the Revolution: Cuban Women's Healing Practices and Knowledge Spaces
Authors: Corrigan Lisa M. 
Published: February 2013

AbstractIn Blessed by Thunder: Memoir of a Cuban Girlhood, Flor Fernandez Barrios examines the consequences of Castro's Revolution and its silencing, censoring, and prohibitions on the writing, speaking, thinking, and performance of public rituals of communities and families. Barrios is able to use the history of storytelling and orality to integrate her roles as a daughter, granddaughter, and healer into a larger history of Cuban women who have preserved knowledge practices that exist outside of the state's masculine identity and its sanctioned social and medical institutions. As Barrios rewrites the Cuban Revolution through the collective memories of three generations of women in her family, she articulates her own Cuban-ness as well as her relationship to Afro-Cuban culture, an often-overlooked connection that tells us as much about upper-class culture on the island during this period in the early 1960s as it does about Afro-Cuban life practices such as Santería.
Collocutio: Transformational Speeches
Authors: Ornatowski Cezar M. , Marin Noemi 
Published: February 2013

AbstractTransformational speeches represent the relationship between rhetoric and history, particularly attempts to exert control at moments of change in the life of a political community. Such speeches re-imagine the definition, principles, or motivation of a community. They also enlarge the scope and vocabulary of political speech. Finally, they interpret or constitute situations at the boundary between past and future. Collected in this Collocutio are fresh translations of historically significant transformational speeches from Bulgaria, Cuba, Mexico, Poland, and Romania.
Comparative study of RNA-seq- and Microarray-derived coexpression networks in Arabidopsis thaliana
Authors: Giorgi Federico M. , Del Fabbro Cristian , Licausi Francesco 
Published: February 2013

Abstract
Motivation: Coexpression networks are data-derived representations of genes behaving in a similar way across tissues and experimental conditions. They have been used for hypothesis generation and guilt-by-association approaches for inferring functions of previously unknown genes. So far, the main platform for expression data has been DNA microarrays; however, the recent development of RNA-seq allows for higher accuracy and coverage of transcript populations. It is therefore important to assess the potential for biological investigation of coexpression networks derived from this novel technique in a condition-independent dataset.
Results: We collected 65 publicly available Illumina RNA-seq high quality Arabidopsis thaliana samples and generated Pearson correlation coexpression networks. These networks were then compared with those derived from analogous microarray data. We show how Variance-Stabilizing Transformed (VST) RNA-seq data samples are the most similar to microarray ones, with respect to inter-sample variation, correlation coefficient distribution and network topological architecture. Microarray networks show a slightly higher score in biology-derived quality assessments such as overlap with the known protein–protein interaction network and edge ontological agreement. Different coexpression network centralities are investigated; in particular, we show how betweenness centrality is generally a positive marker for essential genes in A.thaliana, regardless of the platform originating the data. In the end, we focus on a specific gene network case, showing that although microarray data seem more suited for gene network reverse engineering, RNA-seq offers the great advantage of extending coexpression analyses to the entire transcriptome.

RepeatExplorer: a Galaxy-based web server for genome-wide characterization of eukaryotic repetitive elements from next-generation sequence reads
Authors: Novák Petr , Neumann Pavel , Pech Jiří , Steinhaisl Jaroslav , Macas Jiří 
Published: February 2013

Abstract
Motivation: Repetitive DNA makes up large portions of plant and animal nuclear genomes, yet it remains the least-characterized genome component in most species studied so far. Although the recent availability of high-throughput sequencing data provides necessary resources for in-depth investigation of genomic repeats, its utility is hampered by the lack of specialized bioinformatics tools and appropriate computational resources that would enable large-scale repeat analysis to be run by biologically oriented researchers.
Results: Here we present RepeatExplorer, a collection of software tools for characterization of repetitive elements, which is accessible via web interface. A key component of the server is the computational pipeline using a graph-based sequence clustering algorithm to facilitate de novo repeat identification without the need for reference databases of known elements. Because the algorithm uses short sequences randomly sampled from the genome as input, it is ideal for analyzing next-generation sequence reads. Additional tools are provided to aid in classification of identified repeats, investigate phylogenetic relationships of retroelements and perform comparative analysis of repeat composition between multiple species. The server allows to analyze several million sequence reads, which typically results in identification of most high and medium copy repeats in higher plant genomes.
Implementation and availability: RepeatExplorer was implemented within the Galaxy environment and set up on a public server at http://repeatexplorer.umbr.cas.cz/. Source code and instructions for local installation are available at http://w3lamc.umbr.cas.cz/lamc/resources.php.

Do Labor Market Policies have Displacement Effects? Evidence from a Clustered Randomized Experiment *
Authors: Crépon Bruno , Duflo Esther , Gurgand Marc , Rathelot Roland , Zamora Philippe 
Published: February 2013

AbstractThis article reports the results from a randomized experiment designed to evaluate the direct and indirect (displacement) impacts of job placement assistance on the labor market outcomes of young, educated job seekers in France. We use a two-step design. In the first step, the proportions of job seekers to be assigned to treatment (0%, 25%, 50%, 75%, or 100%) were randomly drawn for each of the 235 labor markets (e.g., cities) participating in the experiment. Then, in each labor market, eligible job seekers were randomly assigned to the treatment, following this proportion. After eight months, eligible, unemployed youths who were assigned to the program were significantly more likely to have found a stable job than those who were not. But these gains are transitory, and they appear to have come partly at the expense of eligible workers who did not benefit from the program, particularly in labor markets where they compete mainly with other educated workers, and in weak labor markets. Overall, the program seems to have had very little net benefits.

Authors: Fisher John R. 
Published: February 2013

In this brief, the authors describe the identification of Tobacco streak virus associated with a virus-like leaf symptom on Hosta spp. The identity of the virus was confirmed by ELISA and PCR using cDNAs synthesized from dsRNA template and immuncaptured virions and primers to amplify the movement protein and capsid protein genes. This is the first report of TSV infecting Hosta in Ohio, and to our knowledge in the United States. Accepted for publication 17 December 2012. Published 22 January 2013.
Fluoroscopic Radiation Exposure in Spinal Surgery
Authors: Mulconrey Daniel S. 
Published: February 2013

Study Design:
Prospective in vivo investigation of fluoroscopic radiation exposure during spinal surgery.

Objective:
To quantify the total amount of radiation dosage and identify techniques to maintain safe levels of fluoroscopic exposure in the operating room.

Summary of Background Data:
No previous study has performed an in vivo examination of fluoroscopic radiation exposure to the spinal surgeon and operating room personnel. Previous similar studies were in vitro, used older versions of fluoroscopy, and increased fluoro times associated with pedicle screw placement.

Methods:
Thirty-five surgeries were evaluated in 18 males and 17 females (mean age 52.4 y; range, 26.0–79.4). Surgeries included 37 lumbar levels fused, 45 lumbar decompressions, 8 anterior cervical fusions, and 19 transforaminal lumbar interbody fusion procedures. Spinal instrumentation was implemented in all fusion procedures (104 lumbar pedicle screws, 14 iliac, 22 anterior cervical). Radiation dosimetry was obtained through unprotected badges placed on surgeon’s chest, first assistant chest, cranial and caudal end of operating table.

Results:
Total fluoroscopic time was 37.01 minutes. Mean fluoroscopic time with lumbar spine instrumentation was greater than decompression alone (1.74 vs. 0.22 min). Total fluoroscopic radiation exposure was obtained for surgeon (1225 mrem), first assistant (369 mrem), cranial table (92 mrem), and caudal table (150 mrem). Mean dose/min (mrem/min) was calculated for surgeon (33.1), first assistant (9.97), cranial table (2.48), and caudal table (4.05). To remain below the maximum yearly permissible level of radiation, the estimated total number of minutes for the surgeon would be 453.

Conclusions:
The results of this in vivo study indicate fluoroscopic dosage to the spine surgeon remains below the annual maximum limit of radiation exposure. Increasing distance from radiation source led to a significantly diminished in vivo dosimetry reading. Monitoring fluoroscopic time and maintaining a distance from the beam source, radiation exposure to the spine surgeon may be kept within current safety standards.
Posterior Cervical Fusion With Recombinant Human Bone Morphogenetic Protein-2
Authors: Dorward Ian G. , Buchowski Jacob M. , Stoker Geoffrey E. , Zebala Lukas P. 
Published: February 2013

Study Design:
Retrospective case series.

Objective:
The purpose of this study was to determine the fusion rate and evaluate the complications associated with the application of recombinant human bone morphogenetic protein-2 (rhBMP-2) in posterior cervical fusion.

Summary of Background Data:
The rates of fusion and complications associated with the use of rhBMP-2 in posterior cervical fusion is unclear, though recent work has shown up to a 100% fusion rate.

Methods:
We independently reviewed consecutive series of patients who underwent posterior cervical, occipitocervical, or cervicothoracic instrumented fusion augmented with rhBMP-2. Two surgeons at a tertiary-referral, academic medical center performed all operations, and each patient had a minimum of 2-year follow-up. Fusion status was determined by bony bridging on computed tomography scans, absence of radiolucency around instrumentation, and absence of motion on lateral flexion/extension radiographs.

Results:
Fifty-seven patients with a mean age of 56.7±13.2 years and mean follow-up of 37.7±20.6 months were analyzed. Forty-eight patients (84.2%) had undergone previous cervical surgery, and 42.1% had a preexisting nonunion. Constructs spanned 5.6±2.6 levels; 19.3% involved the occiput, whereas 61.4% crossed the cervicothoracic junction. The mean rhBMP-2 dose was 21.1±8.7 mg per operation. Iliac crest autograft was used for 29.8% of patients. Six patients (10.5%) experienced nonunion; only 2 required revision. In each case of nonunion, instrumentation crossed the occipitocervical or cervicothoracic junction. However, none of the analyzed variables was statistically associated with nonunion. Fourteen patients (24.6%) suffered complications, with 7 requiring additional surgery.

Conclusions:
The observed fusion rate of rhBMP-2–augmented posterior cervical, occipitocervical, and cervicothoracic fusions was 89.5%. This reflects the complicated nature of the patients included in the current study and demonstrates that rhBMP-2 cannot always overcome the biomechanical challenges entailed in spanning the occipitocervical or cervicothoracic junction.
Thoracoscopic Vertebrectomy for Thoracolumbar Junction Fractures and Tumors
Authors: Ray Wilson Z. , Schmidt Meic H. 
Published: February 2013

Study Design:
Retrospective study.

Objective:
The authors evaluated the surgical technique and learning curve for video-assisted thoracoscopic surgery (VATS) for treating thoracolumbar junction burst fractures and bony tumors by examining surgical data and outcome for the first 30 VATS procedures performed by a single surgeon at a training institution.

Summary of Background Data:
VATS is commonly used in the treatment of early-stage lung cancer. Widespread use of this technique among neurosurgeons is limited by the lack of cases and the steep learning curve.

Methods:
This study was a retrospective case series of the first 30 T12 and L1 thoracoscopic vertebrectomies from 2003 to 2008. The sample was limited to 1 surgeon and 1 region of the spine to minimize the potential variation so that a learning curve could be assessed. Surgical data and outcomes were analyzed. Estimated blood loss and operation time were analyzed using a linear generalized estimating equation model with a first-order autoregression correlation structure.

Results:
The average operative time for thoracoscopic corpectomy was 270±65 minutes (range, 160–416 min). Operating room time decreased significantly after the first 3 operations. The authors observed a stable linear decrease in operating time over the course of the study. The average blood loss during the thoracoscopic procedure was 433±330 mL (range, 100–1500 mL) and did not change as the series progressed. Complications and conversions to open procedures occurred in 2 patients and were evenly distributed throughout the series.

Conclusions:
Thoracoscopic vertebrectomy at the thoracolumbar junction has a relatively long learning curve. In this series, operating room time improved dramatically after the first 3 cases but continued to improve subsequently. The learning curve can be accomplished without an increase in blood loss, complications, rate of conversion to open procedures, or frequency of misplaced instrumentation.

BackgroundThere is a keen interest to develop research systems and increase research output in the 14 Pacific Island Forum Countries (PIFC) to support development of policies and practice based on locally relevant research evidence.AimsTo assess the quantity and characteristics of reproductive health research output by each country (14 PIFC) from 2000 to 2011 using New Zealand's reproductive research outputs as the reference.MethodsA systematic search of the literature using a broad definition of reproductive health.ResultsThere were 174 papers published in the PIFC from 2000 to 2011 compared with 628 papers published in New Zealand (NZ). Most (57%) of the PIFC papers were from Papua New Guinea (PNG), although Samoa had the most papers by population (10/100 000). Five of the countries did not have a single publication. The majority of papers from both the PIFC and NZ were observational studies (72 vs 36%). Authors from Australia were responsible for 34% of PIFC publications followed by 25% from PNG. Sixty‐three per cent of papers by PIFC sole and first authors were published in local journals, whereas 86% of non‐PIFC authors published in international journals.ConclusionThere is a need for reproductive research in PIFC. PNG had the most publications on the back of a well‐funded dedicated research institute and a significant collaboration with Australian researchers. The large number of papers in PIFC countries without PIFC authors raises the question about the need to require non‐PIFC researchers to enter into genuine research partnerships in order to build research capacity in the PIFC.
Translation of Integrative Behavioral Couple Therapy to a Web‐based Intervention
Authors: Doss Brian D. , Benson Lisa A. , Georgia Emily J. , Christensen Andrew 
Published: February 2013

Couple therapy—across a number of different theoretical approaches—has been shown to be an effective treatment for a variety of individual and relationship difficulties. Moreover, recent studies have demonstrated that the effects of several approaches last at least 2–5 years after the end of treatment. However, couple therapy has a critical limitation: most distressed couples—including those who eventually divorce—do not seek couple therapy. Thus, although we recognize there are notable advances in the treatment approaches described in this special section, we argue that traditional approaches to couple therapy need to be supplemented by alternative interventions before we can make a profound, population‐level impact on relationship distress and divorce. To this end, we translated Integrative Behavioral Couple Therapy into a self‐help, web‐based program—www.OurRelationship.com. Through a combination of tailored feedback, filmed examples, and interactive education, the online program first helps couples identify a core problem in their relationship. The program then assists partners in coming to a new and more accurate understanding of the problem they jointly identified and subsequently brings them together in a structured conversation to share their new understandings with each other. Finally, based on this shared conceptualization, the program supports couples in making concrete changes in their relationship. In this article, we discuss the rationale for the program, describe the core components of the website, and illustrate these components with a case example. Relative advantages and disadvantages compared with traditional couple therapy are presented.

Published: February 2013

AbstractAimTo compare detection of the second mesiobuccal (MB2) canal in maxillary molar teeth using cone‐beam computed tomography (CBCT) with different voxel sizes against conventional radiographic examination when the MB1 was unprepared, prepared and filled.MethodologyRadiographic examination and 0.2‐, 0.25‐ and 0.3‐mm CBCT (n = 89) were performed in 3 stages: S1, no first mesiobuccal (MB1) canal preparation or filling; S2, after MB1 preparation and filling; and S3, after MB1 root canal filling removal and canal repreparation. Images were analysed using the i‐Cat software. After RE and CBCT acquisition in S3, all the samples were clarified to directly visualize the presence of the MB2 canal. All images were analysed by a blinded, previously calibrated examiner. Accuracy, specificity and sensitivity were compared using analysis of variance (P < 0.05 level of significance).ResultsMB2 root canals were detected in 67% of the samples. Overall, radiographic examination was associated with lower mean accuracy values for detecting MB2 than CBCT regardless of the MB1 condition. The MB1 root canal condition did not influence MB2 detection in 0.2‐mm voxel images. The presence of root fillings in the MB1 canals reduced the detection of MB2 canals, especially in the 0.3‐ and 0.25‐mm voxel‐size images (P < 0.05).ConclusionCBCT was associated with higher mean values of specificity and sensibility than radiographic examination for the detection of MB2 canals. When endodontic retreatment is necessary removal of the root filling prior to the CBCT examination eliminates artefacts, thereby permitting the use of the 0.3‐mm voxel protocol that has good diagnostic performance and lower radiation dose.
Age‐Related Changes in Prosodic Features of Maternal Speech to Prelingually Deaf Infants with Cochlear Implants
Authors: Kondaurova Maria V. , Bergeson Tonya R. , Xu Huipuing 
Published: February 2013

This study investigated prosodic and structural characteristics of infant‐directed speech to hearing‐impaired infants as they gain hearing experience with a cochlear implant over a 12‐month period of time. Mothers were recorded during a play interaction with their HI infants (N = 27, mean age 18.4 months) at 3, 6, and 12 months postimplantation. Two separate control groups of mothers with age‐matched normal‐hearing infants (NH‐AM) (N = 21, mean age 18.1 months) and hearing experience‐matched normal‐hearing infants (NH‐EM) (N = 24, mean age 3.1 months) were recorded at three testing sessions. Mothers produced less exaggerated pitch characteristics, a larger number of syllables per utterance, and faster speaking rate when interacting with NH‐AM as compared to HI infants. Mothers also produced more syllables and demonstrated a trend suggesting faster speaking rate in speech to NH‐EM relative to HI infants. Age‐related modifications included decreased pitch standard deviation and increased number of syllables in speech to NH‐AM infants and increased number of syllables in speech to HI and NH‐EM infants across the 12‐month period. These results suggest that mothers are sensitive to the hearing status of their infants and modify characteristics of infant‐directed speech over time.

AbstractRoot rot caused by Rhizoctonia bataticola is a serious threat in cotton. Field experiments were conducted to study the influences of intercropping system in cotton with inorganic fertilizer and two bioinoculants (Azospirillum and Pseudomonas) on root rot incidence and yield of cotton. The results revealed that among the intercropping systems, cotton intercropping with Sesbania aculeata (1 : 1 ratio) recorded the highest rhizosphere colonization of Pseudomonas fluorescens in the year 2007 and 2008 and the lowest root rot incidence of 1.40, 2.49 and 3.90; 1.02, 2.22 and 5.98% at the vegetative, flowering and maturity stages in the year 2007 and 2008, respectively. From nutrient management practices, integration of Azospirillum and Pseudomonas with 50% recommended dose of NPK recorded the highest rhizosphere colonization of P. fluorescens in both years and the lowest root rot incidence of 1.40, 2.32 and 3.36; 1.07, 2.01 and 5.25% at vegetative, flowering and maturity stages in 2007 and 2008, respectively. Cotton + S. aculeata recorded the maximum number of sympodial branches (23.5 and 20.62/plant in 2007 and 2008, respectively) and the highest seed cotton yield of 2010 and 1894 kg/ha. The highest cotton equivalent yield (CEY) of 2052 and 1895 kg/ha was recorded in cotton + onion system, which was closely followed by cotton + S. aculeata system that had the CEY of 2010 and 1894 kg/ha in 2007 and 2008, respectively. The increased CEY is due to increased cost of onion compared with S. aculeata. Combined application of 100% recommended dose of NPK and bioinoculants recorded the seed cotton yield of 2227 and 1983 kg/ha and CEY of 2460 and 2190 kg/ha in 2007 and 2008, respectively. The lowest root rot incidence and increased yield in cotton + S. aculeata combined with 50% NPK and bioinoculants could be due to synergistic effect among the bioinoculants and S. aculeata.
