Abstract
Mitochondrial dysfunction activates the mitochondrial retrograde signaling pathway, resulting in large scale changes in gene expression. Mitochondrial retrograde signaling in neurons is poorly understood and whether retrograde signaling contributes to cellular dysfunction or is protective is unknown. We show that inhibition of Ras-ERK-ETS signaling partially reverses the retrograde transcriptional response to alleviate neuronal mitochondrial dysfunction. We have developed a novel genetic screen to identify genes that modify mitochondrial dysfunction in Drosophila. Knock-down of one of the genes identified in this screen, the Ras-ERK-ETS pathway transcription factor Aop, alleviates the damaging effects of mitochondrial dysfunction in the nervous system. Inhibition of Ras-ERK-ETS signaling also restores function in Drosophila models of human diseases associated with mitochondrial dysfunction. Importantly, Ras-ERK-ETS pathway inhibition partially reverses the mitochondrial retrograde transcriptional response. Therefore, mitochondrial retrograde signaling likely contributes to neuronal dysfunction through mis-regulation of gene expression. Loss of mitochondrial function activates the mitochondrial retrograde signaling pathway resulting in large scale changes in nuclear gene transcription. Very little is known about retrograde signaling in the nervous system and how the transcriptional changes affect neuronal function. Here we identify Ras-ERK-ETS signaling as a novel mitochondrial retrograde signaling pathway in the Drosophila nervous system. Inhibition of Ras-ERK-ETS signaling improves neuronal function in Drosophila models of mitochondrial disease. Targeting Ras-ERK-ETS signaling may therefore have therapeutic potential in mitochondrial disease patients. Using a transcriptomic approach, we find that inhibition of Ras-ERK-ETS signaling partially reverses the mitochondrial retrograde transcriptional response. Surprisingly therefore, the mitochondrial retrograde transcriptional response contributes to neuronal dysfunction.

Abstract
Following peripheral axon injury, dysregulation of non-coding microRNAs (miRs) occurs in dorsal root ganglia (DRG) sensory neurons. Here we show that DRG neuron cell bodies release extracellular vesicles, including exosomes containing miRs, upon activity. We demonstrate that miR-21-5p is released in the exosomal fraction of cultured DRG following capsaicin activation of TRPV1 receptors. Pure sensory neuron-derived exosomes released by capsaicin are readily phagocytosed by macrophages in which an increase in miR-21-5p expression promotes a pro-inflammatory phenotype. After nerve injury in mice, miR-21-5p is upregulated in DRG neurons and both intrathecal delivery of a miR-21-5p antagomir and conditional deletion of miR-21 in sensory neurons reduce neuropathic hypersensitivity as well as the extent of inflammatory macrophage recruitment in the DRG. We suggest that upregulation and release of miR-21 contribute to sensory neuron–macrophage communication after damage to the peripheral nerve. Exosomes are known to contain microRNAs (miRs). Here the authors show that dorsal root ganglion neurons release exosomes containing miR-21-5p, which contributes to inflammatory cell recruitment following peripheral nerve injury.

Abstract
The secretome of human amniotic fluid stem cells (AFSCs) has great potential as a therapeutic agent in regenerative medicine. However, it must be produced in a clinically compliant manner before it can be used in humans. In this study, we developed a means of producing a biologically active secretome from AFSCs that is free of all exogenous molecules. We demonstrate that the full secretome is capable of promoting stem cell proliferation, migration, and protection of cells against senescence. Furthermore, it has significant anti-inflammatory properties. Most importantly, we show that it promotes tissue regeneration in a model of muscle damage. We then demonstrate that the secretome contains extracellular vesicles (EVs) that harbor much, but not all, of the biological activity of the whole secretome. Proteomic characterization of the EV and free secretome fraction shows the presence of numerous molecules specific to each fraction that could be key regulators of tissue regeneration. Intriguingly, we show that the EVs only contain miRNA and not mRNA. This suggests that tissue regeneration in the host is mediated by the action of EVs modifying existing, rather than imposing new, signaling pathways. The EVs harbor significant anti-inflammatory activity as well as promote angiogenesis, the latter may be the mechanistic explanation for their ability to promote muscle regeneration after cardiotoxin injury.

Abstract
Part 2 of this narrative review outlines the theoretical and practical bases for assessing the efficacy and effectiveness of conventional medicines and homeopathic products. Known and postulated mechanisms of action are critically reviewed. The evidence for clinical efficacy of products in both categories, in the form of practitioner experience, meta-analysis and systematic reviews of clinical trial results, is discussed. The review also addresses problems and pitfalls in assessing data, and the ethical and negative aspects of pharmacology and homeopathy in veterinary medicine.

Abstract
For many years after its invention around 1796, homeopathy was widely used in people and later in animals. Over the intervening period (1796-2016) pharmacology emerged as a science from Materia Medica (medicinal materials) to become the mainstay of veterinary therapeutics. There remains today a much smaller, but significant, use of homeopathy by veterinary surgeons. Homeopathic products are sometimes administered when conventional drug therapies have not succeeded, but are also used as alternatives to scientifically based therapies and licensed products. The principles underlying the veterinary use of drug-based and homeopathic products are polar opposites; this provides the basis for comparison between them. This two-part review compares and contrasts the two treatment forms in respect of history, constituents, methods of preparation, known or postulated mechanisms underlying responses, the legal basis for use and scientific credibility in the 21st century. Part 1 begins with a consideration of why therapeutic products actually work or appear to do so.

Abstract
BACKGROUND Studies of workers exposed to benzene at average air concentrations below one part per million suggest that benzene, a known hematotoxin, causes hematopoietic damage even at low exposure levels. However, evidence of such effects outside of occupational settings and for other volatile organic compounds (VOCs) is limited. OBJECTIVE To investigate associations between ambient exposures to five VOCs, including benzene, and hematologic parameters among adult residents of the U.S. Gulf Coast. MATERIALS AND METHODS Blood concentrations of selected VOCs were measured in a sample of adult participants in the Gulf Long-term Follow-up Study (GuLF STUDY) during 2012 and 2013. Complete blood counts with differentials were also performed on a subset of participants (n=406). We used these data together with detailed questionnaire data to estimate adjusted associations between blood BTEXS (benzene, toluene, ethylbenzene, o-xylene, m/p-xylene, and styrene) concentrations and hematologic parameters using generalized linear models. RESULTS We observed inverse associations between blood benzene concentrations and hemoglobin concentration and mean corpuscular hemoglobin concentration, and a positive association with red cell distribution width among tobacco smoke-unexposed participants (n=146). Among tobacco smoke-exposed participants (n=247), we observed positive associations between blood VOC concentrations and several hematologic parameters, including increased white blood cell and platelet counts, suggestive of hematopoietic stimulation typically associated with tobacco smoke exposure. Most associations were stronger for benzene than for the other VOCs. CONCLUSIONS Our results suggest that ambient exposure to BTEXS, particularly benzene, may be associated with hematologic effects, including decreased hemoglobin concentration, mean corpuscular hemoglobin concentration, and increased red cell distribution width.

Abstract
OBJECTIVE Our objective was to improve understanding of the differences in use behavior and exposure when smoking menthol and non-menthol cigarettes using a 2-part cross-over design. METHODS Adult daily smokers were assigned randomly to alternate between 2 weeks of exclusively smoking a menthol test cigarette or a non-menthol test cigarette. Urine and saliva were collected for biomarker measurements; carbon monoxide (CO) was measured, and participants smoked test cigarettes through a CreSS® smoking topography device during 3 clinic visits. Participants turned in their cigarette butts from the test periods for determination of mouth level nicotine and completed subjective questionnaires related to the test cigarettes. RESULTS Regardless of cigarette preference, participants had higher salivary cotinine when smoking the non-menthol test cigarette, but there were no significant differences detected in urine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol between the 2 test cigarettes. Mouth level nicotine, puff volume, and puff duration were significantly higher when smoking the menthol brand. Both menthol and non-menthol smokers reported significantly lower enjoyment and satisfaction scores for test cigarettes compared with their brand of choice. CONCLUSIONS Our results suggest that mentholation has an effect on measures of smoking behavior and that mouth level nicotine is a useful indicator of between-brand smoke exposure.

Abstract
Clean cooking has emerged as a major concern for global health and development because of the enormous burden of disease caused by traditional cookstoves and fires. The World Health Organization has developed new indoor air quality guidelines that few homes will be able to achieve without replacing traditional methods with modern clean cooking technologies, including fuels and stoves. However, decades of experience with improved stove programs indicate that the challenge of modernizing cooking in impoverished communities includes a complex, multi-sectoral set of problems that require implementation research. The National Institutes of Health, in partnership with several government agencies and the Global Alliance for Clean Cookstoves, has launched the Clean Cooking Implementation Science Network that aims to address this issue. In this article, our focus is on building a knowledge base to accelerate scale-up and sustained use of the cleanest technologies in low- and middle-income countries. Implementation science provides a variety of analytical and planning tools to enhance effectiveness of clinical and public health interventions. These tools are being integrated with a growing body of knowledge and new research projects to yield new methods, consensus tools, and an evidence base to accelerate improvements in health promised by the renewed agenda of clean cooking.

Abstract
The hypothalamic GnRH neurons are a small group of cells that regulate the reproductive axis. These neurons are specified within the olfactory placode, delaminate from this structure, and then migrate to enter the forebrain before populating the hypothalamus. We have used microarray technology to analyze the transcriptome of the olfactory placode at a number of key time points for GnRH ontogeny using the chick embryo. This resulted in the identification of a large number of genes whose expression levels change significantly over this period. This repertoire includes those genes that are known to be important for GnRH neuronal development as well as many novel genes, such as the serotonin receptor 1A, HTR1A. We find that HTR1A is expressed in the region of the olfactory placode that generates GnRH neurons. We further show that when this receptor is inactivated using a selective HTR1A antagonist as well as a gene knockdown approach using RNAi, this resulted in delayed migration causing the GnRH neurons to stall just outside the forebrain. These findings implicate HTR1A as being important for GnRH neuronal migration from the olfactory placode to the forebrain. Our study thus extends the repertoire of genes involved in GnRH neuron biology and thus identifies new candidate genes that can be screened for in patients who do not show mutations in any of the previously identified hypogonadotrophic hypogonadism/Kallmann syndrome genes.

Abstract
Urinary diamines are biomarkers of diisocyanate exposure. Diisocyanates are considered as skin and respiratory sensitizers and are the most frequently reported cause of occupational asthma. Herein we report on the development and validation of an ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the measurement of five aromatic diamines, 4,4'-methylenedianiline (MDA), 2,4-toluenediamine (4TDA), 2,6-toluenediamine (6TDA), 1,5-naphthalenediamine (NDA), and p-phenylenediamine (PPDA) in human urine. The method incorporates sample preparation steps, which include a 4 h acid hydrolysis followed by high-throughput solid-phase extraction prior to chromatographic separation. Chromatographic separation was achieved using a C18 reversed phase column with gradient elution of basic mobile phases (pH 9.2). The duty cycle of the method was less than 5 min, including both the column equilibration and autosampler movement. Analytical detection was performed using positive ion atmospheric pressure chemical ionization tandem mass spectrometry (APCI-MS/MS) in scheduled multiple reaction monitoring (sMRM) mode. Excellent linearity was observed over standard calibration curve concentration ranges of 3 orders of magnitude with method detection limit ranging from 10 to 100 pg/mL. The interday and intraday reproducibility and accuracy were within ±15%. This method is fast, accurate, and reproducible and is suitable for assessment of exposure to the most common aromatic diisocyanates within targeted groups as well as larger population studies such as the National Health and Nutrition Examination Survey (NHANES).

Abstract
BACKGROUND A 2-day consensus working meeting, hosted by the United States National Institutes of Health and the Veterans Administration, focused on issues related to dissemination and implementation (D&I) research in measurement and reporting. Meeting participants included 23 researchers, practitioners, and decision makers from the USA and Canada who concluded that the field would greatly benefit from measurement resources to enhance the ease, harmonization, and rigor of D&I evaluation efforts. This paper describes the findings from an environmental scan and literature review of resources for D&I measures. FINDINGS We identified a total of 17 resources, including four web-based repositories and 12 static reviews or tools that attempted to synthesize and evaluate existing measures for D&I research. Thirteen resources came from the health discipline, and 11 were populated from database reviews. Ten focused on quantitative measures, and all were generated as a resource for researchers. Fourteen were organized according to an established D&I theory or framework, with the number of constructs and measures ranging from 1 to more than 450. Measure metadata was quite variable with only six providing information on the psychometric properties of measures. CONCLUSIONS Additional guidance on the development and use of measures are needed. A number of approaches, resources, and critical areas for future work are discussed. Researchers and stakeholders are encouraged to take advantage of a number of funding mechanisms supporting this type of work.

Abstract
An electronic survey was responded to by 233 fellows of the American College of Dentists and by 586 graduates of four dental schools. Rate of involvement and weighted number of leadership positions held gradually increased until about age 45 to 50, then declined more steeply. Leadership potential manifested itself as early as dental school and the characteristics most associated with leadership were professionalism and a strong ethic, while available time and personal sacrifice were not regarded as great drawbacks.

Abstract
Social media consist of powerful tools that impact not only communication but relationships among people, thus posing an inherent challenge to the traditional standards of who we are as dental educators and what we can expect of each other. This article examines how the world of social media has changed dental education. Its goal is to outline the complex issues that social media use presents for academic dental institutions and to examine these issues from personal, professional, and legal perspectives. After providing an update on social media, the article considers the advantages and risks associated with the use of social media at the interpersonal, professional, and institutional levels. Policies and legal issues of which academic dental institutions need to be aware from a compliance perspective are examined, along with considerations and resources needed to develop effective social media policies. The challenge facing dental educators is how to capitalize on the benefits that social media offer, while minimizing risks and complying with the various forms of legal constraint.

Abstract
The goal of this article is to describe the broad curricular constructs surrounding teaching and learning about social media in dental education. This analysis takes into account timing, development, and assessment of the knowledge, skills, attitudes, and behaviors needed to effectively use social media tools as a contemporary dentist. Three developmental stages in a student's path to becoming a competent professional are described: from undergraduate to dental student, from the classroom and preclinical simulation laboratory to the clinical setting, and from dental student to licensed practitioner. Considerations for developing the dental curriculum and suggestions for effective instruction at each stage are offered. In all three stages in the future dentist's evolution, faculty members need to educate students about appropriate professional uses of social media. Faculty members should provide instruction on the beneficial aspects of this communication medium and help students recognize the potential pitfalls associated with its use. The authors provide guidelines for customizing instruction to complement each stage of development, recognizing that careful timing is not only important for optimal learning but can prevent inappropriate use of social media as students are introduced to novel situations.

Abstract
OBJECTIVE The purpose of this single-blind, crossover study was to compare plaque removal associated with a new manual toothbrush, the O'Nano and a best-selling, commercially available manual toothbrush, the Oral-B Indicator 40. The O'Nano toothbrush has a patented "one-piece molded design" made of Thermal Plastic Urethane, a plastic that has been used in medical devices. METHODOLOGY Over a six-week period, 40 subjects participated. Following random assignment, 22 subjects started with the O'Nano brush and the remaining started with the Oral-B Indicator 40 brush. Crossover occurred after two-weeks' use of each brush (two-week washout in between). Plaque was scored before and after brushing using the Turesky modification of the Quigley-Hein Index (T/Q-H). Plaque accumulation was 12 to 18 hours prior to examination and brushing. RESULTS Thirty-nine subjects completed the study; one subject was dropped for non-compliance. Groups were virtually identical at the onset in plaque level scores by study design. In comparison to baseline, both brushes achieved significant (p < 0.001) plaque reductions (gains) with a matched-paired comparison t-test. The O'Nano brush gain was 0.445 (18%) per subject and the Oral-B Indicator 40 brush was 0.504 (20%) per subject. The difference in plaque removal capability between brushes averaged 0.60 in favor of the Oral-B Indicator 40 brush, a non-significant (p = 0.20) finding determined by a matched-paired comparison t-test, which is identical to the repeated measures ANOVA when there are two groups and two time periods. Standard deviation (SD) was smaller for the O'Nano brush in plaque reduction scores (0.183 < 0.235). This difference was tested and found to be non-significant with this particular group size. CONCLUSION Statistical analysis of T/Q-H scores demonstrated that the O'Nano brush is comparable to the Oral-B Indicator 40 brush under the conditions of this study protocol. With this small study group the slight differences in plaque removal efficiency between both brushes was not significant. The unique "one-piece molded" design of the O'Nano brush was not evaluated for durability in comparison to a more conventional brush, the Oral-B 40.

Abstract
OBJECTIVES To determine the effective dose and CT dose index (CTDI) for a range of imaging protocols using the Sirona GALILEOS(®) Comfort CBCT scanner (Sirona Dental Systems GmbH, Bensheim, Germany). METHODS Calibrated optically stimulated luminescence dosemeters were placed at 26 sites in the head and neck of a modified RANDO(®) phantom (The Phantom Laboratory, Greenwich, NY). Effective dose was calculated for 12 different scanning protocols. CTDI measurements were also performed to determine the dose-length product (DLP) and the ratio of effective dose to DLP for each scanning protocol. RESULTS The effective dose for a full maxillomandibular scan at 42 mAs was 102 ± 1 μSv and remained unchanged with varying contrast and resolution settings. This compares with 71 μSv for a maxillary scan and 76 μSv for a mandibular scan with identical milliampere-seconds (mAs) at high contrast and resolution settings. CONCLUSIONS Changes to mAs and beam collimation have a significant influence on effective dose. Effective dose and DLP vary linearly with mAs. A collimated maxillary or mandibular scan decreases effective dose by approximately 29% and 24%, respectively, as compared with a full maxillomandibular scan. Changes to contrast and resolution settings have little influence on effective dose. This study provides data for setting individualized patient exposure protocols to minimize patient dose from ionizing radiation used for diagnostic or treatment planning tasks in dentistry.

Abstract
Air breathing is an essential motor function for vertebrates living on land. The rhythm that drives breathing is generated within the central nervous system and relayed via specialised subsets of spinal motor neurons to muscles that regulate lung volume. In mammals, a key respiratory muscle is the diaphragm, which is innervated by motor neurons in the phrenic nucleus. Remarkably, relatively little is known about how this crucial subtype of motor neuron is generated during embryogenesis. Here, we used direct differentiation of motor neurons from mouse embryonic stem cells as a tool to identify genes that direct phrenic neuron identity. We find that three determinants, Pou3f1, Hoxa5 and Notch, act in combination to promote a phrenic neuron molecular identity. We show that Notch signalling induces Pou3f1 in developing motor neurons in vitro and in vivo. This suggests that the phrenic neuron lineage is established through a local source of Notch ligand at mid-cervical levels. Furthermore, we find that the cadherins Pcdh10, which is regulated by Pou3f1 and Hoxa5, and Cdh10, which is controlled by Pou3f1, are both mediators of like-like clustering of motor neuron cell bodies. This specific Pcdh10/Cdh10 activity might provide the means by which phrenic neurons are assembled into a distinct nucleus. Our study provides a framework for understanding how phrenic neuron identity is conferred and will help to generate this rare and inaccessible yet vital neuronal subtype directly from pluripotent stem cells, thus facilitating subsequent functional investigations.

Abstract
Abstract
Epidemiologists and public health researchers are increasingly interested in the translational value of their research. However, only a small fraction (estimated at 14 percent) of scientific discoveries are ever translated into public health practice, and the process from discovery to translation is exceedingly slow – approximately 17 years. There is a clear need for greater speed, relevance and application of scientific discoveries into programs and policies. In the past decade, the National Cancer Institute and the National Institutes of Health (NIH) expanded their mission to include practice-based research to best understand how scientific discoveries and evidence-based interventions can best be translated not only into clinical or community applications but to have a broader impact on population health through changes in policy and practice. Through trans-NIH funding announcements, 15 institutes and centers at the NIH currently are soliciting proposals for research in the field of dissemination and implementation research in health. For the purposes of these announcements, dissemination is defined as the targeted distribution of information and intervention materials to a specific public health or clinical practice audience. The intent is to spread (or scale-up) and sustain knowledge and the associated evidence-based interventions. Implementation is the use of strategies to adopt and integrate evidence-based health interventions and change practice patterns within specific settings. In this presentation we will describe in more detail the emerging field of dissemination and implementation research in health, identify priority research areas that are highlighted in the program announcements, and provide advice on how to prepare an application. We also will provide additional information on training opportunities in dissemination and implementation science, and we will describe resources that are available for cancer researchers. Finally, we will discuss emerging areas including issues such as sustainability, reach and representativeness, cost-effectiveness, and de-implementation (particularly in regard to overtreatment and overdiagnosis in cancer.)
