Does a Nonclassical Signaling Mechanism Underlie an Increase of Estradiol-Mediated Gonadotropin-Releasing Hormone Receptor Binding in Ovine Pituitary Cells?1

Estradiol-17beta (E2) is the major regulator of GnRH receptor (GnRHR) gene expression and number during the periovulatory period; however, the mechanisms underlying E2 regulation of the GNRHR gene remain undefined. Herein, we find that E2 conjugated to BSA (E2-BSA) mimics the stimulatory effect of E2 on GnRH binding in primary cultures of ovine pituitary cells. The time course for maximal GnRH analog binding was similar for both E2 and E2-BSA. The ability of E2 and E2-BSA to increase GnRH analog binding was blocked by the estrogen receptor (ER) antagonist ICI 182,780. Also, increased GnRH analog binding in response to E2 and the selective ESR1 agonist propylpyrazole triol was blocked by expression of a dominant-negative form of ESR1 (L540Q). Thus, membrane-associated ESR1 is the likely candidate for mediating E2 activation of the GNRHR gene. As cAMP response element binding protein (CREB) is an established target for E2 activation in gonadotrophs, we next explored a potential role for this protein as an intracellular mediator of the E2 signal. Consistent with this possibility, adenoviral-mediated expression of a dominant-negative form of CREB (A-CREB) completely abolished the ability of E2 to increase GnRH analog binding in primary cultures of ovine pituitary cells. Finally, the presence of membrane-associated E2 binding sites on ovine pituitary cells was demonstrated using a fluorescein isothiocyanate conjugate of E2-BSA. We suggest that E2 regulation of GnRHR number during the preovulatory period reflects a membrane site of action and may proceed through a nonclassical signaling mechanism, specifically a CREB-dependent pathway.
Arenicella chitinivorans sp. nov., a gammaproteobacterium isolated from the sea urchin Strongylocentrotus intermedius.

A strictly aerobic, Gram-stain-negative, rod-shaped, non-motile and yellow-pigmented bacterial strain, designated KMM 6208(T), was isolated from a sea urchin. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that this novel isolate was affiliated to the class Gammaproteobacteria and formed a robust cluster with Arenicella xantha KMM 3895(T) with 98.2 % 16S rRNA gene sequence similarity. Strain KMM 6208(T) grew in the presence of 0.5-5 % NaCl and at a temperature range of 4-38 °C. The isolate was oxidase-positive and hydrolysed aesculin, casein, chitin, gelatin, starch and Tweens 40 and 80. The prevalent fatty acids of strain KMM 6208(T) were C16 : 1ω7c, iso-C16 : 0, iso-C18 : 0, C18 : 1ω7c and C16 : 0. The polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified aminophospholipid, and the major isoprenoid quinone was Q-8. The DNA G+C content of strain KMM 6208(T) was 46.3 mol%. The DNA-DNA relatedness value of strain KMM 6208(T) with Arenicella xantha KMM 3895(T) was 5 %. Molecular data in a combination with phenotypic findings strongly suggest inclusion of this novel strain in the genus Arenicella as a representative of a novel species for which the name Arenicella chitinivorans sp. nov. is proposed. The type strain is KMM 6208(T) ( = KCTC 12711(T) = LMG 26983(T)).
Emergence of sigh rhythmogenesis in the embryonic mouse

The respiratory oscillator of the pre‐Bötzinger complex (preBötC) can generate distinct inspiratory motor patterns underlying eupnoeic and sigh‐related rhythmic activities. The preBötC can generate ‘fictive’ eupnoea at embryonic stages, but its ability to also generate sigh‐like activity remains unexplored at prenatal stages. Here, using mouse brainstem slice preparations, we show that sigh‐like activity emerges during embryonic development but later than eupnoeic rhythmogenesis. Inspiratory cells active during the latter are also active during fictive sighing, although a small subset of neurons was found to fire exclusively during sighs. Effective glycinergic inhibitory signalling is also required for sigh generation. We conclude that the developmental emergence of a sigh‐generating capability occurs after the onset of eupnoeic rhythmogenesis and requires an appropriate maturational state of chloride‐mediated glycinergic synaptic transmission.
Interference of the CD30–CD30L Pathway Reduces Atherosclerosis Development

Objective—Costimulatory molecules tightly control immune responses by providing positive signals that promote T-cell activation or by transducing inhibitory signals that limit T-cell responses. CD30 and CD30L are members of the tumor necrosis factor receptor superfamily and are involved in the activation and proliferation of T and B cells, which have been implicated in the initiation and progression of atherosclerosis. In the present study, we thus aimed to determine the role of the CD30–CD30L pathway in the development of atherosclerosis. Methods and Results—Western-type diet–fed low-density lipoprotein receptor–deficient mice were treated with an anti-CD30L antibody for 8 weeks, which resulted in a reduction of atherosclerotic lesion formation in the aortic root by 35%. Reduced numbers of adventitial CD3+ T cells were found in anti-CD30L–treated mice, whereas no differences were observed in collagen and macrophage content of the atherosclerotic lesions. B-cell and mast cell responses were also not affected on anti-CD30L treatment. Interestingly, splenocyte proliferation was reduced by 53%, whereas T-cell numbers were concomitantly reduced in anti-CD30L–treated mice compared with control mice. These data thus indicate that the CD30–CD30L pathway solely exerts its function via inhibition of T-cell responses. Conclusion—In the present study, we are the first to show that interruption of the CD30–CD30L pathway reduced initial atherosclerosis development by modulating T-cell function.
Foreign ministries and limits to organisational learning in Central Eastern Europe

Joining the European Union (EU) has had a transformative effect for the foreign policies of the new member states and the Ministries of Foreign Affairs (MFAs). There is a growing body of literature that analyses Europeanisation of foreign policies of EU member states as a result of their participation in Common Foreign and Security Policy. At the same time, the significance of learning in bringing change in foreign policy remains underexplored avenue of international relations (IR) and foreign policy analysis (FPA). This article demonstrates how learning processes can contribute to the processes of Europeanisation and shows what are the possible inhibitors to institutionalisation of the lessons learnt at individual level.
Postpartum tuberculosis incidence and mortality among HIV-infected women and their infants in Pune, India, 2002-2005.

BACKGROUND In contrast with many other countries, isoniazid preventative therapy is not recommended in clinical care guidelines for human immunodeficiency virus (HIV)-infected persons with latent tuberculosis (TB) in India. METHODS Seven hundred fifteen HIV-infected mothers and their infants were prospectively followed up for 1 year after delivery at a public hospital in Pune, India. Women were evaluated for active TB during regular clinic visits, and tuberculin skin tests were performed. World Health Organization definitions for confirmed, probable, and presumed TB were used. Poisson regression was performed to determine correlates of incident TB, and adjusted probabilities of mortality were calculated. RESULTS Twenty-four of 715 HIV-infected women who were followed up for 480 postpartum person-years developed TB, yielding a TB incidence of 5.0 cases per 100 person-years (95% confidence interval [CI], 3.2-7.4 cases per 100 person-years). Predictors of incident TB included a baseline CD4 cell count <200 cells/mm(3) (adjusted incident rate ratio [IRR], 7.58; 95% CI, 3.07-18.71), an HIV load >50,000 copies/mL (adjusted IRR, 3.92; 95% CI, 1.69-9.11), and a positive tuberculin skin test result (adjusted IRR, 3.08; 95% CI, 1.27-7.47). Three (12.5%) of 24 women with TB died, compared with 7 (1.0%) of 691 women without TB (IRR, 12.2; 95% CI, 2.03-53.33). Among 23 viable infants with mothers with TB, 2 received a diagnosis of TB. Four infants with mothers with TB died, compared with 28 infants with mothers without TB (IRR, 4.71; 95% CI, 1.19-13.57). Women with incident TB and their infants had a 2.2- and 3.4-fold increased probability of death, respectively, compared with women without active TB and their infants, controlling for factors independently associated with mortality (adjusted IRR, 2.2 [95% CI, 0.6-3.8] and 3.4 [95% CI, 1.22-10.59], respectively). CONCLUSIONS Among Indian HIV-infected women, we found a high incidence of postpartum TB and associated postpartum maternal and infant death. Active screening and targeted use of isoniazid preventative therapy among HIV-infected women in India should be considered to prevent postpartum maternal TB and associated mother-to-child morbidity and mortality.
Elevated C-Reactive Protein and Hypoalbuminemia Measured before Resection of Colorectal Liver Metastases Predict Postoperative Survival

Background: Few studies have investigated whether the Glasgow Prognostic Score (GPS), an inflammation-based prognostic score measured before resection of colorectal liver metastasis (CRLM), can predict postoperative survival. Patients and Methods: Sixty-three consecutive patients who underwent curative resection for CRLM were investigated. GPS was calculated on the basis of admission data as follows: patients with both an elevated C-reactive protein (>10 mg/l) and hypoalbuminemia (<35 g/l) were allocated a GPS score of 2. Patients in whom only one of these biochemical abnormalities was present were allocated a GPS score of 1, and patients with a normal C-reactive protein and albumin were allocated a score of 0. Results: Significant factors concerning survival were the number of liver metastases (p = 0.0044), carcinoembryonic antigen level (p = 0.0191), GPS (p = 0.0029), grade of liver metastasis (p = 0.0033), and the number of lymph node metastases around the primary cancer (p = 0.0087). Multivariate analysis showed the two independent prognostic variables: liver metastases ≧3 (relative risk 2.83) and GPS1/2 (relative risk 3.07). Conclusions: GPS measured before operation and the number of liver metastases may be used as novel predictors of postoperative outcomes in patients who underwent curative resection for CRLM.
Performance characteristics obtained for a new 3-dimensional lutetium oxyorthosilicate-based whole-body PET/CT scanner with the National Electrical Manufacturers Association NU 2-2001 standard.

UNLABELLED This article reports the results of performance measurements obtained for the lutetium oxyorthosilicate (LSO)-based whole-body PET/CT scanner Biograph 16 HI-REZ with the National Electrical Manufacturers Association (NEMA) NU 2-2001 standard. The Biograph 16 HI-REZ combines a multislice (16-slice) spiral CT scanner with a PET scanner composed of 24.336 LSO crystals arranged in 39 rings. The crystal dimensions are 4.0x4. 0x20 mm3, and the crystals are organized in 13x13 blocks coupled to 4 photomultiplier tubes each. The 39 rings allow the acquisition of 81 images 2.0 mm thick, covering an axial field of view of 162 mm. The low- and high-energy thresholds are set to 425 and 650 keV, respectively, acquiring data within a 4.5-ns-wide coincidence window. METHODS Performance measurements for the LSO-based PET/CT scanner were obtained with the NEMA NU 2-2001 standard, taking into account issues deriving from the presence of intrinsic radiation. RESULTS The results obtained with the NEMA NU 2-2001 standard measurements were as follows: average transverse and axial spatial resolutions (full width at half maximum) at 1 cm and at 10 cm off axis of 4.61 (5.10) mm and 5.34 (5.91) mm, respectively; average sensitivity of 4.92 counts per second per kilobecquerel for the 2 radial positions (0 and 10 cm); 34.1% system scatter fraction; and peak noise equivalent count (NEC) rates of 84.77 kilocounts per second (kcps) at 28.73 kBq/mL (k=1 in the NEC formula; noiseless random correction) and 58.71 kcps at 21.62 kBq/mL (k=2; noisy random correction). CONCLUSION The new integrated PET/CT system Biograph 16 HI-REZ has good overall performance, with, in particular, a high resolution, a low scatter fraction, and a very good NEC response.
A time domain approach for the fluctuation analysis of heart rate related to instantaneous lung volume

A time domain technique for estimating transfer characteristics from fluctuations of instantaneous lung volume (ILV) to heart rate (HR) is presented. An effective procedure for estimating the impulse response of HR to ILV is proposed. Pre- and post-processing procedures, including prefiltering of the HR signal, preenhancement of the high frequency content of the ILV signal, and post-filtering of the estimated impulse response, together with a random breathing technique, are shown to effectively reduce spurious transfer gain so as to get a stable estimate of the impulse response. Analysis of the data collected from fourteen healthy male subjects in various conditions revealed that there are three components in the impulse response: fast positive, delayed slow negative, and oscillatory. The effects of the autonomic blocking agents propranolol and atropine on these transfer characteristics are also described. <<ETX>>
Functional Network Reconstruction Reveals Somatic Stemness Genetic Maps and Dedifferentiation‐Like Transcriptome Reprogramming Induced by GATA2

Somatic stem cell transplantation holds great promise in regenerative medicine. The best‐characterized adult stem cells are mesenchymal stem cells (MSCs), neural stem cells (NSCs), and CD133+ hematopoietic stem cells (HSCs). The applications of HSCs are hampered since these cells are difficult to maintain in an undifferentiated state in vitro. Understanding genes responsible for stem cell properties and their interactions will help on this issue. The construction of stem cell genetic networks will also help to develop rational strategies to revert somatic cells back to a stem‐like state. We performed a systemic study on human CD133+ HSCs, NSCs, MSCs, and embryonic stem cells and two different progenies of CD133+ HSCs, microvascular endothelial cells (MVECs) and peripheral blood mononuclear cells. Genes abundant in each or in all three somatic stem cells were identified. We also observed complex genetic networks functioning in postnatal stem cells, in which several genes, such as PTPN11 and DHFR, acted as hubs to maintain the stability and connectivity of the whole genetic network. Eighty‐seven HSC genes, including ANGPT1 and GATA2, were independently identified by comparing CD34+CD33−CD38− hematopoietic stem cells with CD34+ precursors and various matured progenies. Introducing GATA2 into MVECs resulted in dedifferentiation‐like transcriptome reprogramming, with HSC genes (such as ANGPT1) being up and endothelial genes (such as EPHB2) being down. This study provides a foundation for a more detailed understanding of human somatic stem cells. Expressing the newly discovered stem cell genes in matured cells might lead to a global reversion of somatic transcriptome to a stem‐like status.
Real-time vehicle detection using Haar-SURF mixed features and gentle AdaBoost classifier

On-road vehicle detection is one of the key techniques in intelligent driver systems and has been an active research area in the past years. Considering the high demand for real-time and robust vehicle detection method, a novel vehicle detection method has been proposed. This paper presents a real-time vehicle detection algorithm which uses cascade classifier and Gentle AdaBoost classifier with Haar-SURF mixed features. We built up a large database including vehicles and non-vehicles for training and testing. A pipeline is then presented to solve the detection problem. Firstly, lane detection is employed to reduce the search space to a ROI. Secondly, the cascade classifier is applied to generate some candidates. Finally, the single decision classifier evaluates the candidates and provides the target vehicle. The experiments and on-road tests prove it to be a real-time and robust algorithm. In addition, we demonstrate the effectiveness and practicability of the algorithm by porting it to an Android mobile.
Direct Evidence for a Binding between Cognitive and Motor Functions in Humans: A TMS Study

During voluntary motor actions, the cortico-spinal (CS) excitability is known to be modulated, on the one hand by cognitive (intention-related) processes and, on the other hand, by motor (performance-related) processes. Here, we studied the way these processes interact in the tuning of CS excitability during voluntary wrist movement. We used transcranial magnetic stimulation (TMS) both as a reliable tool for quantifying the CS excitability, through the motor-evoked potentials (MEPs), and as a central perturbation evoking a movement (because the stimulation intensity was above threshold) with subjects instructed to prepare (without changing their muscle activation) either to let go or to resist to this evoked movement. We studied the simultaneous evolution of both the motor performance and the MEPs in the wrist flexor and extensor, separately for the successful trials (on average, 66 of the trials whatever the condition) and the unsuccessful trials; this allowed us to dissociate the intentionand performance-related processes. To their great surprise, subjects were found able to cognitively prepare themselves to resist a TMS-induced central perturbation; they all reported an important cognitive effort on the evoked movement. Moreover, because TMS only evoked short-latency MEPs (and no long-latency components), the amplitude of these short-latency MEPs was found to be related in a continuous way to the actual movement whatever the prior intention. These results demonstrate that prior intention allows an anticipatory modulation of the CS excitability, which is not only selective (as already known) but also efficient, giving the intended motor behavior a real chance to be realized. This constitutes a direct evidence of the role of the CS excitability in the binding between cognitive and motor processes in humans.
Personalized 2 D color maps

2D color maps are often used to visually encode complex data characteristics such as heat or height. The comprehension of color maps in visualization is affected by the display (e.g., a monitor) and the perceptual abilities of the viewer. In this paper we present a novel method to measure a user's ability to distinguish colors of a two-dimensional color map on a given monitor. We show how to adapt the color map to the user and display to optimally compensate for the measured deficiencies. Furthermore, we improve user acceptance of the calibration procedure by transforming the calibration into a game. The user has to sort colors along a line in a 3D color space in a competitive fashion. The errors the user makes in sorting these lines are used to adapt the color map to his perceptual capabilities. & 2016 Elsevier Ltd. All rights reserved.
Psychophysiological Reactivity Profiles of Partner-Violent Men With Borderline or Psychopathic Personality Features: The Role of Empathy

Borderline and psychopathic features have been linked to unique psychophysiological reactivity profiles. Studies have suggested that levels of psychophysiological reactivity for partner-violent men cannot be attributed to personality features alone. This study tested cognitive and affective empathy as moderators of relations between borderline personality, Factor 1 psychopathy, and psychophysiological reactivity using a community sample of 135 male participants and their female partners. Cognitive empathy moderated the relation between borderline personality features and heart rate reactivity. Affective empathy moderated the relation between Factor 1 psychopathy features and heart rate reactivity. However, directions of these interactions were contrary to original predictions. Understanding unique empathy deficits may be beneficial for identifying ways to minimize relationship conflict, manage arousal, and decrease violence.
Spiritual needs as defined by Swedish nursing staff.

A study was undertaken to describe how Swedish nursing staff at six different units characterize spiritual needs in a broad context, including both religious and existential issues. Another aim was to study whether there are any special groups of patients for whom these needs are considered to be of utmost importance. A questionnaire comprising two open-ended questions (the focus of the study) and six background questions was mailed to 191 nurses. Data were obtained from 141 nurses who worked on the oncology, palliative, neurological, neurosurgery and psychiatric units or in nursing homes. Data from the open-ended questions were analysed using content analysis and classified into three categories: (i) (general) spiritual issues, (ii) religious issues, and (iii) existential issues. Sub-categories of the latter were (a) meaning, (b) freedom, (c) isolation and (d) death, i.e. the four central issues in existentialism as previously defined by existential philosophers. A majority of the nurses only had limited theoretical knowledge about definitions. Nevertheless, their suggestions for improved spiritual and existential support contained essential elements that could be allocated to the three main categories. They had some difficulty distinguishing between spiritual and psychosocial care. According to the nurses, special groups of interest for spiritual and existential support were severely ill, dying persons and immigrants who actively practiced their religion. We conclude that there is a willingness to pay attention to spiritual and existential needs, but nurses still have difficulty defining what such care should include. The study revealed that nursing staff needed, and also made inquiries about, more education in order to deepen their knowledge.
High-quality 3D correction of ring and radiant artifacts in flat panel detector-based cone beam volume CT imaging

The use of an x-ray flat panel detector is increasingly becoming popular in 3D cone beam volume CT machines. Due to the deficient semiconductor array manufacturing process, the cone beam projection data are often corrupted by different types of abnormalities, which cause severe ring and radiant artifacts in a cone beam reconstruction image, and as a result, the diagnostic image quality is degraded. In this paper, a novel technique is presented for the correction of error in the 2D cone beam projections due to abnormalities often observed in 2D x-ray flat panel detectors. Template images are derived from the responses of the detector pixels using their statistical properties and then an effective non-causal derivative-based detection algorithm in 2D space is presented for the detection of defective and mis-calibrated detector elements separately. An image inpainting-based 3D correction scheme is proposed for the estimation of responses of defective detector elements, and the responses of the mis-calibrated detector elements are corrected using the normalization technique. For real-time implementation, a simplification of the proposed off-line method is also suggested. Finally, the proposed algorithms are tested using different real cone beam volume CT images and the experimental results demonstrate that the proposed methods can effectively remove ring and radiant artifacts from cone beam volume CT images compared to other reported techniques in the literature.
