Abstract
About one third of individuals living with epilepsy have treatment-resistant seizures. Alternative therapeutic strategies are thus urgently needed. One potential novel treatment target is microRNA-induced silencing, which is differentially regulated in epilepsy. Inhibitors (antagomirs) of specific microRNAs have shown therapeutic promise in preclinical epilepsy studies; however, these studies were mainly conducted in male rodent models, and research into microRNA regulation in females and by female hormones in epilepsy is scarce. This is problematic because female sex and the menstrual cycle can affect the disease course of epilepsy and may, therefore, also alter the efficacy of potential microRNA-targeted treatments. Here, we used the proconvulsant microRNA miR-324-5p and its target, the potassium channel Kv4.2, as an example to test how microRNA-induced silencing and the efficacy of antagomirs in epilepsy are altered in female mice. We showed that Kv4.2 protein is reduced after seizures in female mice similar to male mice; however, in contrast to male mice, microRNA-induced silencing of Kv4.2 is unchanged, and miR-324-5p activity, as measured by the association with the RNA-induced silencing complex, is reduced in females after seizure. Moreover, a miR-324-5p antagomir does not consistently reduce seizure frequency or increase Kv4.2 in female mice. As a possible underlying mechanism, we found that miR-324-5p activity and silencing of Kv4.2 in the brain were differentially correlated with plasma levels of 17β-estradiol and progesterone. Our results suggest that hormonal fluctuations in sexually mature female mice influence microRNA-induced silencing and could alter the efficacy of potential future microRNA-based treatments for epilepsy in females.Significance StatementMicroRNA-induced silencing is currently investigated in preclinical studies as a potential novel class of treatment target for epilepsy; however, surprisingly little is known about if and how microRNA-induced silencing is regulated by biological sex and if microRNA therapeutics are as effective in females as they are in males. This study shows that microRNA silencing of the potassium channel Kv4.2 and the functional activity of its targeting microRNA, miR-324-5p, change with plasma levels of estrogens and progesterone and that an inhibitor of miR-324-5p is less effective in female mice to suppress seizures. These findings are significant as they suggest microRNA-induced silencing as a novel molecular mechanism contributing to sex differences in epilepsy that could impact future therapy development.

Abstract
Antineutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) comprises a group of multisystem disorders involving severe, systemic, small-vessel vasculitis with short- and long term serious and life-threating complications. Despite the simplification of treatment, fundamental aspects concerning assessment of its efficacy and its adaptation to encountered complications or to the relapsing/remitting/subclinical disease course remain still unknown. The pathogenesis of AAV is complex and unique, and despite the progress achieved in the last years, much has not to be learnt. Foremost, there is still no accurate marker enabling us to monitoring disease and guide therapy. Therefore, the disease management relays often on clinical judgment and follows a" trial and error approach". In the recent years, an increasing number of new molecules s have been explored and used for this purpose including genomics, B- and T-cell subpopulations, complement system factors, cytokines, metabolomics, biospectroscopy and components of our microbiome. The aim of this review is to discuss both the role of known historical and clinically established biomarkers of AAV, as well as to highlight potential new ones, which could be used for timely diagnosis and monitoring of this devastating disease, with the goal to improve the effectiveness and ameliorate the complications of its demanding therapy.

Abstract
Background: Many patients with cancer are diagnosed through an emergency presentation, which is associated with inferior clinical and patient-reported outcomes compared with those of patients who are diagnosed electively or through screening. Reducing the proportion of patients with cancer who are diagnosed as emergencies is, therefore, desirable; however, the optimal means of achieving this aim are uncertain owing to the involvement of different tumor, patient and health-care factors, often in combination. Methods: We searched the literature to identify all population-based studies that examined emergency presentation as a diagnosis or independent variable. Results: Most relevant evidence relates to patients with colorectal or lung cancer in a few economically developed countries, and defines emergency presentations contextually (that is, whether patients presented to emergency health-care services and/or received emergency treatment shortly before their diagnosis) as opposed to clinically (whether patients presented with life-threatening manifestations of their cancer). Consistent inequalities in the risk of emergency presentations by patient characteristics and cancer type have been described, but limited evidence is available on whether, and how, such presentations can be prevented. Evidence on patients' symptoms and health-care use before presentation as an emergency is sparse. Conclusion: In this review, we describe the extent, causes and implications of a diagnosis of cancer following an emergency presentation, and provide recommendations for public health and health-care interventions, and research efforts aimed at addressing this underresearched aspect of cancer diagnosis.

Abstract
BACKGROUND Augmentation with human alpha-1 proteinase inhibitor is the only specific treatment for Alpha-1-Antitrypsin Deficiency (AATD), a rare genetic disease with symptoms of progressive COPD. OBJECTIVES A prospective long-term exploration of outcomes during the "Alpha-1-Mobile" home care AAT augmentation program in seven advanced-stage patients. METHODS Patients received weekly i. v. AAT augmentation and COPD therapy. Symptoms, lung function, health status, quality-of-life aspects, and safety were documented continuously. Outcomes during six years of home care augmentation therapy were observed and evaluated on an inter- and intraindividual basis. FEV1 profiles were compared to pre-program data. RESULTS The seven patients had a mean age of 56.7 (40-68) years and had previously received augmentation for 8.8 (1-19) years. Compared to the three-year preprogram period, functional decline of FEV1 (ΔFEV1 0.47 L vs 0.17 L) slowed. Mean QoL scores showed seasonal fluctuations in the first three years of observation, and then stabilized. All blood samples tested exceeded the protective threshold of 50 mg/dL with a dose of 60 mg AAT/kg/week. Less than one exacerbation-related hospitalization occurred per patient-year. No adverse events of related to augmentation therapy were observed. CONCLUSIONS Home care with i. v. augmentation therapy by medical professionals contributes to optimum care through consistent treatment and close health-status monitoring in our collective. Exacerbation-related hospitalizations were largely avoided. "Alpha-1-Mobile" was well accepted, practical, and safe.

Abstract
OBJECTIVE To compare cognitive-behavioral therapy (CBT), panic-focused psychodynamic psychotherapy (PFPP), and applied relaxation training (ART) for primary DSM-IV panic disorder with and without agoraphobia in a 2-site randomized controlled trial. METHOD 201 patients were stratified for site and DSM-IV agoraphobia and depression and were randomized to CBT, PFPP, or ART (19-24 sessions) over 12 weeks in a 2:2:1 ratio at Weill Cornell Medical College (New York, New York) and University of Pennsylvania ("Penn"; Philadelphia, Pennsylvania). Any medication was held constant. RESULTS Attrition rates were ART, 41%; CBT, 25%; and PFPP, 22%. The most symptomatic patients were more likely to drop out of ART than CBT or PFPP (P = .013). Outcome analyses revealed site-by-treatment interactions in speed of Panic Disorder Severity Scale (PDSS) change over time (P = .013). At Cornell, no differences emerged on improvement on the primary outcome, estimated speed of change over time on the PDSS; at Penn, ART (P = .025) and CBT (P = .009) showed greater improvement at treatment termination than PFPP. A site-by-treatment interaction (P = .016) for a priori-defined response (40% PDSS reduction) showed significant differences at Cornell: ART 30%, CBT 65%, PFPP 71% (P = .007), but not at Penn: ART 63%, CBT 60%, PFPP 48% (P = .37). Penn patients were more symptomatic, differed demographically from Cornell patients, had a 7.2-fold greater likelihood of taking medication, and had a 28-fold greater likelihood of taking benzodiazepines. However, these differences did not explain site-by-treatment interactions. CONCLUSIONS All treatments substantially improved panic disorder with or without agoraphobia, but patients, particularly the most severely ill, found ART less acceptable. CBT showed the most consistent performance across sites; however, the results for PFPP showed the promise of psychodynamic psychotherapy for this disorder.

Abstract
Over the past 3.5 years 220 patients with aneurysmal subarachnoid hemorrhage were treated in the Department of Neurosurgery University of Vienna Medical School using either endovascular techniques (Guglielmi Detachable Coils) or open craniotomy with aneurysm clipping. A retrospective analysis was undertaken to assess whether any difference in outcome could be correlated with the treatment choice. The patients were stratified as to 1) Hunt and Hess grade at time of treatment, 2) method of treatment, and 3) clinical outcome at 2–4 weeks following treatment. The outcomes in this population of patients were consistent with recent published series regardless of whether the aneurysms were treated with microvascular surgery or endovascular surgery. There was a trend toward better outcome in a relatively small sub-group of patients presenting as Hunt and Hess grade III who were treated by the endovascular method. Guglielmi detachable coils have been available for a relatively short time, and although early results are promising, the ultimate long-term efficacy of the coils will have to be assessed.

Abstract
Clinically significant separation anxiety [SA] has been identified as being common among patients who do not respond to psychiatric interventions, regardless of intervention type (pharmacological or psychotherapeutic), across anxiety and mood disorders. An attachment formation and maintenance domain has been proposed as contributing to anxiety disorders. We therefore directly determined prevalence of SA in a population of adult treatment non-responders suffering from primary anxiety. In these separation anxious nonresponders, we pilot-tested an SA-focused, attachment-based psychotherapy for anxiety, Panic-Focused Psychodynamic Psychotherapy-eXtended Range [PFPP-XR], and assessed whether hypothesized biomarkers of attachment were engaged. We studied separation anxiety [SA] in 46 adults (ages 23-70 [mean 43.9 (14.9)]) with clinically significant anxiety symptoms (Hamilton Anxiety Rating Scale [HARS]≥15), and reporting a history of past non-response to psychotherapy and/or medication treatments. Thirty-seven (80%) had clinically significant symptoms of separation anxiety (Structured Clinical Interview for Separation Anxiety Symptoms [SCI-SAS] score≥8). Five of these subjects completed an open clinical trial of Panic Focused Psychodynamic Psychotherapy eXtended Range [PFPP-XR], a 21-24 session, 12-week manualized attachment-focused anxiolytic psychodynamic psychotherapy for anxiety. Patients improved on "adult threshold" SCI-SAS (current separation anxiety) (p=.016), HARS (p=0.002), and global severity, assessed by the Clinical Global Impression Scale (p=.0006), at treatment termination. Salivary oxytocin levels decreased 67% after treatment (p=.12). There was no significant change in high or low frequency HRV after treatment, but change in high frequency HRV inversely correlated with treatment change in oxytocin (p<.02), and change in low frequency HRV was positively associated with change in oxytocin (p<.02). SA is surprisingly prevalent among non-responders to standard anti-anxiety treatments, and it may represent a novel transdiagnostic target for treatment intervention in this population. Anxiety and global function improved in a small trial of a brief, manualized, attachment-focused psychodynamic psychotherapy, potentially supporting the clinical relevance of attachment dysfunction in this sample. The large decrease in oxytocin levels with treatment, although not statistically significant in this very small sample, suggests the need for further study of oxytocin as a putative biomarker or mediator of SA response. These pilot data generate testable hypotheses supporting an attachment domain underlying treatment-resistant anxiety, and new treatment strategies.

Abstract
Scientific misconduct has been defined as fabrication, falsification, and plagiarism. Scientific misconduct has occurred throughout the history of science. The US government began to take systematic interest in such misconduct in the 1980s. Since then, a number of studies have examined how frequently individual scientists have observed scientific misconduct or were involved in it. Although the studies vary considerably in their methodology and in the nature and size of their samples, in most studies at least 10% of the scientists sampled reported having observed scientific misconduct. In addition to studies of the incidence of scientific misconduct, this review considers the recent increase in paper retractions, the role of social media in scientific ethics, several instructional examples of egregious scientific misconduct, and potential methods to reduce research misconduct.

Abstract
Abstract
Objective: Oncotype DxTM (ODx) is a gene expression profile test that is rapidly gaining popularity for its ability to stratify breast cancer patients according to risk of distant recurrence and suggest the potential benefit of adjuvant chemotherapy (CTx). Presently, National Comprehensive Cancer Network (NCCN) guidelines suggest use of ODx for all patients with node negative (or micrometastatic node positive disease), hormone receptor positive breast cancer with a primary tumor measuring over 5mm. However, if risk factors predictive of a high recurrence score (RS) were defined, clinicians would be better able to tailor use of ODx. This study was undertaken to identify standard clinicopathologic factors that correlate with a high RS by ODx, and to determine whether these factors or RS most influenced receipt of CTx. We also measured compliance with NCCN guidelines regarding ODx utilization.
Methods and Materials: We performed an IRB approved retrospective review of women with invasive breast cancer treated at Yale Cancer Center from 2008-2012 to identify patients that received ODx testing, and abstracted clinical and tumor characteristics including: age, tumor size, grade, histology, lymphovascular invasion (LVI), number of involved nodes, size of nodal metastasis, presence of extracapsular extension, hormone receptor status (including percent positive), HER2 status (by FISH), RS, and receipt of CTx. The RS was categorized into low (<18), intermediate (18-30), and high score (>30). We assessed the association between these characteristics and both high RS as well as CTx receipt using Chi squared tests and Wilcoxon ranked test as appropriate. Characteristics with a p-value <0.1 in bivariate analysis were included in logistic models to estimate the odds of a high RS and receiving CTx.
Results: We identified 432 women with a median age of 58 years. RS was low, intermediate, and high in 56%, 37%, and 7%, respectively. Median tumor size was 1.6cm (range 0.1-13.2). Differentiation was rated as well, moderate, or poor in 32%, 60%, and 8%, respectively. Tumors were hormone receptor positive in 99%. ODx was used outside of NCCN guidelines in 12%. CTx was given to 30% of patients. Younger age, HER2-positivity, LVI, poor differentiation, progesterone receptor positivity (PR+) 50% or less, and RS were associated with receipt of CTx (p< = 0.01) in bivariate analyses. High RS remained independently associated with CTx receipt in multivariate analysis. Poor differentiation, PR+ 50% or less, and HER2-positivity were significantly associated with a high RS (p<0.01), and all remained independently associated with high RS in multivariate analysis. Patients with any one of these three factors had 18% odds of a high RS, versus just 1% among those without such risk factors.
Conclusions: High RS independently influences recommendations for chemotherapy. Poor differentiation, PR+ 50% or less, and HER2-positivity were associated with a high RS. In the absence of any of these three factors, the likelihood of a high RS is minimal. Noncompliance with NCCN guidelines was observed.

Abstract
In the long history of the study of the nervous system, there have been a number of major developments that involved radical and permanent changes in fundamental beliefs and assumptions about the nervous system and in tactics and strategies for studying it. These may be termed Revolutions in Neuroscience. This essay considers eight of these, ranging from the 6th century BCE to the end of the 20th century.

Abstract
In addition to its well known calcemic actions, 1,25-dihydroxyvitamin D-3 [1,25(OH)(2)D] exhibits differentiating and antiproliferative effects in several types of cancer cells. 1,25(OH)(2)D receptors (VDR) as well as 1,25(OH)(2)D-mediated growth-inhibition have been demonstrated in human prostate cancer cell lines. In order to further develop model systems for the study of 1,25(OH)(2)D action and to elucidate the mechanism of growth-inhibition, we studied several human prostate cell lines immortalized with either simian virus 40 (SV40) or human papillomavirus type 18 (HPV). The SV40-transformed cell lines P69SV40-T and P153SV40-T were not growth-inhibited by 1,25(OH)(2)D at concentrations as high as 100 nM, whereas the HPV-transformed cells PZ-HPV-7 and CA-HPV-10 were growth-inhibited. All cell lines expressed VDR, and VDR mRNA was demonstrated by Northern blot analysis. All cells exhibited induction of 24-hydroxylase mRNA, a 1,25(OH)(2)D responsive gene, after 1,25(OH)(2)D treatment. In an attempt to understand the apparent dissociation of 1,25(OH)(2)D actions in the SV40-transformed cells, we turned to the human prostate cancer cell line DU 145. These cells, like the SV40-transformed cells, are not growth-inhibited but demonstrate induction of 24-hydroxylase mRNA after 1,25(OH)(2)D treatment. DU 145 cells contain a mutated retinoblastoma gene (Rb) which contributes to their uncontrolled growth, analogous to the disruption of Rb by SV40 and HPV. We compared DU,145 cells to DU 145 cells transfected with normal Rb (DU 145/Rb). Similar to DU 145, DU 145/Rb cells were not growth-inhibited by 1,25(OH)(2)D, while 24-hydroxylase mRNA was induced. These results suggest that divergent pathways mediate the growth-inhibitory effect of 1,25(OH)(2)D and its induction of 24-hydroxylase. It also appears that the antiproliferative effect of 1,25(OH)(2)D is mediated by an Rb-independent mechanism.

Abstract
We experimentally investigate the mixing and demixing dynamics of Bose-Einstein condensates in the presence of a linear coupling between two internal states. The observed amplitude reduction of the Rabi oscillations can be understood as a result of demixing dynamics of dressed states as experimentally confirmed by reconstructing the spatial profile of dressed state amplitudes. The observations are in quantitative agreement with numerical integration of coupled Gross-Pitaevskii equations without free parameters, which also reveals the criticality of the dynamics on the symmetry of the system. Our observations demonstrate new possibilities for changing effective atomic interactions and studying critical phenomena.

Abstract
BACKGROUND With anterior lumbar interbody fusion (ALIF) alone, the morbidity associated with a posterior approach can be avoided. In this study we evaluated the use of a PEEK cage with an integrated angle-stable locking plate (SynFix-LR™). MATERIAL AND METHODS Thirty-two patients with osteochondrosis at L4/5 or L5/S1 were treated with the SynFix-LR™. Follow-up at 0, 3, 6, 9, 12, and 24 months included the Oswestry Disability Index (ODI), visual analog scale (VAS), and questions regarding satisfaction and use of pain medication. The fusion rate was assessed by X-ray and computed tomography (CT) examination. RESULTS A significant reduction of the ODI and VAS was achieved (p<0.05) with a high rate of patient satisfaction. After 2 years, 79% of the patients were able to dispense with long-term use of analgesics. We observed a fusion rate of 93% (X-ray) and 70% (CT) at final follow-up. CONCLUSION The SynFix-LR™ device is a suitable option for the treatment of monosegmental osteochondrosis at L4/5 and L5/S1 with comparable or superior results in comparison to posterior or combined fusion techniques.

Abstract
Criteria suitable for measuring entanglement between two different potential wells in a Bose-Einstein condensation are evaluated. We show how to generate the required entanglement, utilizing either an adiabatic two-mode or a dynamic four-mode interaction strategy, with techniques that take advantage of s-wave scattering interactions to provide the nonlinear coupling. The dynamic entanglement method results in an entanglement signature with spatially separated detectors, as in the Einstein-Podolsky-Rosen paradox.

Abstract
Acquiring the behavioral significance of sound has repeatedly been shown to correlate with long term changes in response properties of neurons in the adult primary auditory cortex. However, the molecular and cellular basis for such changes is still poorly understood. To address this, we have begun examining the auditory cortical expression of an activity-dependent effector immediate early gene (IEG) with documented roles in synaptic plasticity and memory consolidation in the hippocampus: Arc/Arg3.1. For initial characterization, we applied a repeated 10 min (24 h separation) sound exposure paradigm to determine the strength and consistency of sound-evoked Arc/Arg3.1 mRNA expression in the absence of explicit behavioral contingencies for the sound. We used 3D surface reconstruction methods in conjunction with fluorescent in situ hybridization (FISH) to assess the layer-specific subcellular compartmental expression of Arc/Arg3.1 mRNA. We unexpectedly found that both the intranuclear and cytoplasmic patterns of expression depended on the prior history of sound stimulation. Specifically, the percentage of neurons with expression only in the cytoplasm increased for repeated versus singular sound exposure, while intranuclear expression decreased. In contrast, the total cellular expression did not differ, consistent with prior IEG studies of primary auditory cortex. Our results were specific for cortical layers 3-6, as there was virtually no sound driven Arc/Arg3.1 mRNA in layers 1-2 immediately after stimulation. Our results are consistent with the kinetics and/or detectability of cortical subcellular Arc/Arg3.1 mRNA expression being altered by the initial exposure to the sound, suggesting exposure-induced modifications in the cytoplasmic Arc/Arg3.1 mRNA pool.

Abstract
Today the fame of Alfred Russell Wallace is as the independent codiscoverer with Charles Darwin of the origin of species by natural selection. Although they were on very amiable terms all their lives, 11 years after announcing their discovery, Wallace and Darwin had a major disagreement on the evolution of human cognition. The author considers how this divergence and other disagreements, particularly on the role of instinct, are related to the differences in their class backgrounds, education, experience with non-European cultures, and views on socialism, phrenology, mesmerism, and spiritualism.
