Epigenetic revival of a dead cardiomyocyte through mitochondrial interventions
Authors: Kunkel George H. , Chaturvedi Pankaj , Tyagi Suresh C. 
Published: July 2015

AbstractMitochondrial dysfunction has been reported to underline heart failure, and our earlier report suggests that mitochondrial fusion and fission contributes significantly to volume overload heart failure. Although ample studies highlight mitochondrial dysfunction to be a major cause, studies are lacking to uncover the role of mitochondrial epigenetics, i.e. epigenetic modifications of mtDNA in cardiomyocyte function. Additionally, mitochondrial proteases like calpain and Lon proteases are underexplored. Cardiomyopathies are correlated to mitochondrial damage via increased reactive oxygen species production and free calcium within cardiomyocytes. These abnormalities drive increased proteolytic activity from matrix metalloproteinases and calpains, respectively. These proteases degrade the cytoskeleton of the cardiomyocyte and lead to myocyte death. mtDNA methylation is another factor that can lead to myocyte death by silencing several genes of mitochondria or upregulating the expression of mitochondrial proteases by hypomethylation. Cardiomyocyte resuscitation can occur through mitochondrial interventions by decreasing the proteolytic activity and reverting back the epigenetic changes in the mtDNA which lead to myocyte dysfunction. Epigenetic changes in the mtDNA are triggered by environmental factors like pollution and eating habits with cigarette smoking. An analysis of mitochondrial epigenetics in cigarette-smoking mothers will reveal an underlying novel mechanism leading to mitochondrial dysfunction and eventually heart failure. This review is focused on the mitochondrial dysfunction mechanisms that can be reverted back to resuscitate cardiomyocytes.

Published: July 2015

AbstractThe importance of lipids in the understanding of disease states is constantly increasing. Whilst the link between metabolic disorders and lipids seems to be clear, interpreting lipid regulation in the context of neuropsychiatric disorders is a new approach. Mental disorders account for almost 15% of the total global disease burden with Alzheimer’s disease, depression or schizophrenia being amongst the most widespread mental disorders in the general population. For this reason rapid and early diagnosis is crucial and finding the right biomarkers is of great importance. Lipids appear to be essential in learning the aetiopathology of neuropsychiatric diseases as well as in biomarker research as they are most abundantly present in the brain. This study discusses recent findings in neuropsychiatry in the context of lipid analysis.

Published: July 2015

AbstractSunflower is a crop of world interest that is acquiring economic importance in Mexico. The aim of this study was to determine the effect of nitrogen (N) and phosphorus (P) on the growth of the root system and its relationship with the canopy dry matter and yield and its components of sunflower (Helianthus annuus L.). The planting of cv. Victoria was conducted in Montecillo Mex., of temperate climate in a vertisol under conditions of seasonal rainfall on 16 May, with population density of 5 plants per m2. Treatments consisted in supply 0–200 kg ha−1 of N and P. The time to phenological stages was similar between treatment. The N and in minor degree the P increased grain yield (GY) and oil yield (OY) by increases in the grains number (GN), capitulum area (CA), canopy dry matter (CDM) and radical area (RA). In contrast, the P increase RDM but decrease the CDM/RDM relation. The effect of the interaction N * P on GY, OY indicates it is necessary to seek the best combination of N and P for increased the production of sunflower. The size grain and oil content in the grain did not change with N and P. The growth cycle was 122 days, with a seasonal ETc of 207 mm and 1,369°C d (Heat unit, HU).

Published: July 2015

AbstractCraniopharyngioma is a histologically benign brain malformation with a fundamental role in satiety modulation, causing obesity in up to 52% of patients.To evaluate cardiovascular risk factors, body composition, resting energy expenditure (REE), and energy intake in craniopharyngioma patients and to compare the data with those from children with multifactorial obesity.All obese children and adolescents who underwent craniopharyngioma resection and a control group of children with multifactorial obesity in follow-up between May 2012 and April 2013.Anthropometric measurements, bioelectrical impedance, indirect calorimetry, energy intake, homeostatic model assessment insulin resistance (HOMA-IR), and dyslipidemia were evaluated.Twenty-three patients with craniopharyngioma and 43 controls were included. Children with craniopharyngioma-related obesity had a lower fat-free mass percentage (62.4 vs. 67.5; p=0.01) and a higher fat mass percentage (37.5 vs. 32.5; p=0.01) compared to those with multifactorial obesity. A positive association was found between %REE and %fat-free mass in subjects with multifactorial obesity (68±1% in normal REE vs. 62.6±1% in low REE; p=0.04), but not in craniopharyngioma patients (62±2.7 in normal REE vs. 61.2±1.8% in low REE; p=0.8). No differences were found in metabolic involvement or energy intake.REE was lower in craniopharyngioma patients compared to children with multifactorial obesity regardless of the amount of fat-free mass, suggesting that other factors may be responsible for the lower REE.

Published: July 2015

ABSTRACTPolyacrylonitrile (PAN) was printed into a nanostructured carbon nanopillar arrays using a quick, simple, and highly efficient method called spin-on nanoprinting (SNAP). The mold used to print PAN nanostructures could easily be reproduced via printing an inverse replica of carbon nanopillar arrays. The as-printed carbon nanopillar arrays were further prepared as supercapacitor electrodes. As a result, these nanostructured carbon electrodes display an order of magnitude enhancement in specific capacitance compared to non-nanostructured carbon electrodes.
Kayla’s Story Is Our Story
Authors: Strusberg Tanya 
Published: July 2015

ABSTRACTAs a Lamaze Certified Childbirth Educator, I find myself reading a lot of posts on various birth-related Facebook groups. It’s important for me to know the issues women are talking about, asking about, and concerned about. Late last year, I found myself drawn to the real-time labor of a woman in New Mexico who was desperately trying for a successful vaginal birth after cesarean. She was using the virtual Facebook group as her literal emotional support, and the reaction was unlike anything I have ever seen online before. Literally hundreds of women around the world were following her story and rallying behind her—a woman they had never met. This is Kayla’s story, and it is our story.

Authors: Spatz Diane L. , Froh Elizabeth B. , Schwarz Jessica , Houng Kathy , Brewster Isabel , Myers Carey , Prince Judy , Olkkola Michelle 
Published: July 2015

ABSTRACTResearch demonstrates that although many mothers initiate pumping for their critically ill children, few women are successful at maintaining milk supply throughout their infants’ entire hospital stay. At the Garbose Family Special Delivery Unit (SDU) at the Children’s Hospital of Philadelphia, we care for mothers who have critically ill infants born with complex cardiac and congenital anomalies. Human milk is viewed as a medical intervention at our institution. Therefore, nurses on the SDU wanted to ensure best practice in terms of pumping initiation. This article describes a continuous quality improvement project that ensured mothers pumped early and often. Childbirth educators can play a key role in preparing mothers who are anticipating an infant who will require hospitalization immediately post-birth.

Authors: Mitchell Teri M. , Beal Claudia 
Published: July 2015

ABSTRACTIt is important that expectant parents receive accurate information about the benefits and risks of circumcision as well as the benefits and risks of having an intact foreskin when making a decision about routine infant circumcision (RIC). A pilot study was conducted using the shared decision making (SDM) conceptual model to guide expectant parents through a 3-phase decision-making program about RIC as part of their childbirth education class. The participants showed a high level of preparedness following each of the 3 phases. Preparedness score were highest for those who decided to keep their expected sons’ penises natural. This SDM program was an effective way of guiding expectant parents through the decision-making process for RIC.

Firm-Specific Estimates of Differential Persistence and their Incremental Usefulness for Forecasting and Valuation
Authors: Call Andrew C. , Hewitt Max , Shevlin Terry , Yohn Teri Lombardi 
Published: July 2015

ABSTRACT
Although the differential persistence of accruals and operating cash flows is a firm-specific phenomenon, research seeking to exploit the differential persistence of these earnings components typically employs cross-sectional forecasting models. We find that a model based on firm-specific estimates of the differential persistence of accruals and operating cash flows is incrementally useful for out-of-sample forecasting relative to state-of-the-art cross-sectional models. In doing so, we show that firm-specific estimates of differential persistence are particularly useful when forecasting earnings for more stable firms (e.g., more profitable, lower growth, and less levered firms). We also demonstrate that a trading strategy exploiting investors' fixation on earnings and based on firm-specific estimates of differential persistence earns statistically and economically significant excess returns that are incremental to those generated by trading strategies based on the size of accruals. These results suggest that firm-specific estimates of differential persistence are incrementally informative for forecasting and valuation.

Estimating and Reporting Structural Equation Models with Behavioral Accounting Data
Authors: Hampton Clark 
Published: July 2015

ABSTRACT
Despite prior research explaining the benefits of using structural equation modeling (SEM) for analyzing accounting behavioral data, SEM remains underutilized in accounting behavioral research relative to related and reference domains such as psychology, information systems, and management. Prior research posits the frequency with which accounting behavioral data violate SEM assumptions as one probable reason for this underutilization. Accounting behavioral researchers may be unfamiliar with the techniques and approaches available to develop and estimate structural models when data violate SEM assumptions. Given this unfamiliarity, researches may opt to use less informative techniques. The purpose of this paper is to provide guidance on the testing, judgment, and decision-making processes that influence SEM estimation, analysis, and reporting with accounting behavioral data. A structural model is developed, tested, and evaluated using accounting behavioral data that violate, to varying degrees, the assumptions of SEM.
Do Accounting Faculty Characteristics Impact CPA Exam Performance? An Investigation of Nearly 700,000 Examinations
Authors: Bline Dennis M. , Perreault Stephen , Zheng Xiaochuan 
Published: July 2015

ABSTRACT
While many colleges and universities publicize CPA examination pass rates as evidence of having a high-quality accounting program, some have questioned whether program-specific characteristics are legitimate predictors of examination success. To examine this issue, we empirically investigate the link between accounting faculty characteristics and performance on the CPA examination. We examine the results from nearly 700,000 first-time exam sittings taken during the period 2005–2013 and find that faculty research and teaching specialization has a significant impact on CPA exam performance. That is, when a program has a relatively higher percentage of accounting faculty with expertise in a particular content area tested on the exam (e.g., auditing), graduates achieve higher scores on the related exam section (e.g., AUD). We also find that faculty research productivity and CPA certification status are positively related to candidate exam performance. We believe these results contribute to the existing literature on the determinants of CPA exam success and also provide important insights to those responsible for accounting faculty staffing and development.
Employer Perceptions of Online Accounting Degrees
Authors: Grossman Amanda M. , Johnson Leigh R. 
Published: July 2015

ABSTRACT
This study expands upon the current literature regarding how potential employers perceive the value of online accounting education at both the undergraduate and graduate level. Experimental results demonstrate that employers are significantly more willing to offer employment to an entry-level job applicant whose baccalaureate degree in accounting, from an AACSB-accredited institution, was obtained in a traditional (on campus) or hybrid (blended learning) environment as opposed to an online environment. The reputation of the educational institution as suggested by publication ratings does not significantly affect willingness to hire. Further results suggest that Big 4 employers are equally willing to hire the online accounting graduate as employers from most other types of firms. In addition, employers appear to be more accepting of lower-level, as opposed to upper-level, online accounting coursework and favor applicants who complete a baccalaureate degree on campus and an M.B.A. online, or vice versa, over those who complete both degrees online. Practitioners and students should be aware that, within the aforementioned boundaries, accounting firms are becoming more willing to hire accounting graduates whose academic career includes some online content.
“You Have to Keep Moving, Be Active”: Perceptions and Experiences of Habitual Physical Activity in Older Women With Osteoporosis
Authors: Dohrn Ing-Mari , Ståhle Agneta , Roaldsen Kirsti Skavberg 
Published: July 2015

Background
Physical activity (PA) is essential for older adults with osteoporosis, and health care professionals play important roles in promoting PA and encouraging patients to make healthy choices. However, many factors influence habitual PA, and there is only limited knowledge about the perceptions and experiences of PA among older women with osteoporosis.

Objectives
The purpose of this study was to describe perceptions and experiences of PA and the factors that influence habitual PA among older adults with osteoporosis, impaired balance, and fear of falling.

Design
This was a qualitative interview study applying interpretive content analysis with an inductive approach.

Methods
Informants were a purposeful sample of 18 women, aged 66 to 86 years, with osteoporosis, impaired balance, and fear of falling. Individual, semistructured, face-to-face interviews were recorded, transcribed, condensed, and coded to find subthemes and themes.

Results
The overall theme found was “Physical activity—a tool for staying healthy with osteoporosis.” This overall theme comprised 2 main themes interpreting the challenges and possibilities of being physically active with osteoporosis. These themes were not separate but rather linked to each other like 2 sides of the same coin, with factors that could act as both barriers to and facilitators of PA. Personal preferences and osteoporosis-related concerns influenced habitual PA, and individualization was perceived as important.

Limitations
Some results may be context specific and limit the transferability to people with other cultural or socioeconomic backgrounds.

Conclusions
The women perceived that PA was an important tool to maintain health with osteoporosis and believed that they had a responsibility to use this tool. They had adapted to disease-specific limitations and developed strategies to overcome challenges and barriers to PA. Lack of PA promotion and conflicting advice about PA from physicians created uncertainty. Encouragement and guidance from physical therapists, individually or in groups, were very important.
When the Native Is Also a Non-native: “Retrodicting” the Complexity of Language Teacher Cognition
Authors: Aslan Erhan 
Published: July 2015

Abstract:The impact of native (NS) and non-native speaker (NNS) identities on second or foreign language teachers’ cognition and practices in the classroom has mainly been investigated in ESL/EFL contexts. Using complexity theory as a framework, this case study attempts to fill the gap in the literature by presenting a foreign language teacher in the United States who teaches French as a NS and German as a NNS teacher, at the college level. Specifically, the study explores the interface between NS/NNS identities, teacher cognition, practice, and professional identity. The retrodictive qualitative analysis of semi-structured interviews and classroom observations reveals that the participant teacher’s NS French and NNS German identities influenced her teacher cognition, specifically in beliefs about teaching grammar. In addition, previous language learning experiences affect current decision-making processes in teaching. In terms of teaching practice, the dual NS French and NNS German identity affects teaching practice in the formal areas of language, target culture knowledge and awareness, teaching style, and perceptions about language varieties. Professional identity is construed here as being the mediator of target second language (L2) cultures in the classroom. The implications of teacher cognition as a complex system for L2 teaching and teacher education are discussed.
Advanced Practice Nursing Simulation for Neonatal Skill Competency: A Pilot Study for Successful Continuing Education
Authors: Stephenson Evelyn , Salih Zeynep , Cullen Deborah L. 
Published: July 2015

Background:
Skill readiness remains a challenge for all health care professionals who are involved in direct patient care. Researchers suggest that skill retention may decrease within 6 months of an educational session. The purpose of this study was to explore competency retention for high-risk, low-frequency procedures, specifically, managing a difficult airway and placing a laryngeal mask airway, using a web-based content refresher.

Method:
The pilot study was conducted in two sessions. Session one established clinical skill competency. Six months later, the advanced practice RNs were randomized into two groups. Group 1 reviewed didactic content and participated in a complex airway management simulation. Group 2 participated only in a complex airway management simulation.

Results:
This study showed a positive trend in maintaining competency for a low-frequency procedure for which complex airway management was given, using web-based content review. It is feasible to maintain competency for low-frequency procedures using web-based content refreshers.

Conclusion:
This pilot study benefited advanced practice nurses by providing them with the potential to maintain competency in this high-risk, low-frequency procedure. Continuing education is an important consideration for health care organizations.

Framing o teoría del encuadre en comunicación. Orígenes, desarrollo y panorama actual en España
Authors: Ardèvol-Abreu Alberto 
Published: July 2015

La teoría del framing, traducida al castellano como teoría del encuadre o de los marcos, ha experimentado una rápida evolución desde mediados de los años sesenta, donde encuentra sus orígenes en el campo de la sociología, hasta la actualidad. El framing se ha convertido en un paradigma multidisciplinario que permite abordar globalmente el estudio de los efectos de los medios de comunicación sobre los individuos y los públicos. Lejos de situarse exclusivamente en los emisores de información, el encuadre está localizado en cuatro elementos del proceso de comunicación: el emisor, el receptor, el texto (informativo) y la cultura. El presente artículo, bajo la forma de revisión de la literatura, realiza un recorrido por la teoría desde sus antecedentes en los años cincuenta hasta la actualidad, describiendo además el desarrollo de la investigación sobre framing en España y su estado actual.
