Immunomodulatory effects of human placenta gangliosides. (1990)

The immunomodulatory properties of the major gangliosides of human placenta were studied. All the gangliosides investigated suppressed the cytotoxic activity of human natural killer cells. The magnitude of the inhibitory effect depended on ganglioside structure. Gangliosides GM1, GM3, and GD3 were the most effective suppressors. Some of the placental gangliosides (GD3, GD1a, IV3NeuAc-nLc4Cer, VI3NeuAc-nLc6Cer) also inhibited lymphoblastic transformation, and one of them (GM3) strongly stimulated the Con-A-induced T-suppressor activity of human lymphocytes. It is suggested that the combined action of the placental gangliosides on maternal effector cells may be involved in the defence of the human embryo against the maternal immune system.
Regulation of Insulin-Like Growth Factor-Binding Protein-1 Production in Human Granulosa-Luteal Cells* (1989)

Human follicular fluid contains the insulin-like growth factor-binding protein (IGFBP-1) synthesized by ovarian granulosa cells. We studied the regulation of IGFBP-1 production by the granulosa-luteal cells from the hyperstimulated follicles of patients attending an in vitro fertilization program. The cells were first allowed to attach and recover from the hyperstimulation for 2 days. Then, a protein kinase-C activator, 12-O-tetradecanoyl phorbol-13-acetate (TPA), and adenylate cyclase activators, gonadotropins, FSH, hCG, cholera toxin, or prostaglandin E2 (PGE2) were added to the cells. The gonadotropins failed to increase IGFBP-1 production, whereas it was enhanced by TPA and to a lesser extent by cholera toxin and PGE2. The maximal response to TPA occurred at the concentration of 1.0 ng/mL, and the enhancing effect of TPA was detected at 24 h. PGE2 stimulated IGFBP-1 production; the lowest effective concentration was 10(-8) mol/L. The mean highest response was 4.3-fold and occurred at the PGE2 concentration of 10(-5) mol/L. The effect of PGE2 on IGFBP-1 production became detectable at 24 h, and it continued to increase up to 72 h. PGE2 also increased granulosa-luteal cell progesterone production in a dose- and time-dependent manner. Incorporation of [35S]methionine into immunoreactive IGFBP-1, as detected by sodium dodecyl sulfate-polyacrylamide electrophoresis and fluorography, was also increased by TPA. This suggests that TPA accelerated the synthesis of IGFBP-1. Our results indicate that the production of IGFBP-1 by human granulosa-luteal cells can be regulated both via protein kinase-C- and adenylate cyclase-dependent pathways.
Physical layer specification for wireless sensor networks dedicated to evaluation of buildings energetic performances (2010)

In this paper, we propose an extension of the energy model, and show the influence of the channel on energy consumption. Simulation results show that significant gains are obtained by adjusting the transmission power in function of the kind of link between the central node and individual nodes. Future works are dedicated to develop a cross-layer approach based on the presented works. Indeed, once the transmission power is adjusted, the parameters that can optimize the overall energy system are in relation to the strategies of sleep and wake up of nodes (MAC sub-layer).
Patient-reported dyspnea and health predict waitlist mortality in patients waiting for lung transplantation in Japan (2021)

Both mMRC dyspnea and SGRQ score were significantly associated with waitlist mortality, in addition to other clinical variables such as patients' background, underlying disease, and pulmonary function. Patient-reported dyspnea and health may be measured through multi-dimensional analysis (including subjective perceptions) and for risk stratification regarding waitlist mortality.
Visualisation of abscisic acid and 12-oxo-phytodienoic acid in immature Phaseolus vulgaris L. seeds using desorption electrospray ionisation-imaging mass spectrometry (2017)

The plant hormone abscisic acid (ABA) and the jasmonic acid related-compound 12-oxo-phytodienoic acid (OPDA) play crucial roles in seed development, dormancy, and germination. However, a lack of suitable techniques for visualising plant hormones has restricted the investigation of their biological mechanisms. In the present study, desorption electrospray ionisation-imaging mass spectrometry (DESI-IMS), a powerful tool for visualising metabolites in biological tissues, was used to visualise ABA and OPDA in immature Phaseolus vulgaris L. seed sections. The mass spectra, peak values and chemical formulae obtained from the analysis of seed sections were consistent with those determined for ABA and OPDA standards, as were the precursor and major fragment ions observed in tandem mass spectrometry (MS/MS) imaging. Furthermore, the precursor and fragment ion images showed similar distribution patterns. In addition, the localisation of ABA and OPDA using DESI-IMS was confirmed using liquid chromatography-MS/MS (LC-MS/MS). The results indicated that ABA was mainly distributed in the radical and cotyledon of the embryo, whereas OPDA was distributed exclusively in external structures, such as the hilum and seed coat. The present study is the first to report the visualisation of plant hormones using IMS, and demonstrates that DESI-IMS is a promising technique for future plant hormone research.
Fluoresence Spectra From Vegetable Oils Using Violet And Blue Ld/Led Exitation And An Optical Fiber Spectrometer (2013)

In this article the possibility to detect adulteration of costly olive oils with cheaper vegetable oils using fluorescence spectroscopy is studied. Total luminescence spectra were recorded by measuring the emission spectra in the range 350 nm to 720 nm for excitation wavelengths from 375 nm to 450 nm. Fluorescence spectra of 12 types of olive oil samples were studied. Ten of the olive oil types were purchased locally, while two (samples 1 and 4) were obtained directly from Greek olive oil producers. Analysis of the fatty acid and the tocopherol contents has been performed. Two of the samples exhibit the content of sunflower oils, two are admixtures of sunflower and olive oils, while the remaining eight samples are natural olive oils. The samples show differences in their fluorescence spectra. The latter fact shows that fluorescence spectroscopy can be used for the quick identification of possible adulterations of olive oil, although a more detailed gas chromatographic analysis is needed for the exact quantitative determination of the content of the adulterant.
Androgen Receptor-Ets Protein Interaction Is a Novel Mechanism for Steroid Hormone-mediated Down-modulation of Matrix Metalloproteinase Expression (1996)

Matrix metalloproteinases belong to a family of structurally related enzymes that plays important role in tissue morphogenesis, differentiation, and wound healing. Their expression is negatively regulated by several members of the steroid hormone receptor family. This is thought to occur through interaction of the steroid receptors with the transcription factor AP-1 that is otherwise required for positive regulation. Here, we demonstrate that AP-1 is not always a target for down-regulation of expression of matrix metalloproteinases by steroid receptors. Androgen receptor negatively regulates matrix metalloproteinase-1 expression not through AP-1 but through a family of Ets-related transcription factors that are also required for positive regulation. This negative regulation is specific for the androgen receptor. It does not require the DNA binding activity but needs amino-terminal sequences of the receptor. These results identify a novel regulatory pathway for negative regulation utilized by a member of the steroid hormone receptor family for down-regulating the expression of matrix metalloproteinases.

Abstract WP41: Peri-Procedural Arterial Spin Labeling and Dynamic Susceptibility contrast Perfusion in Detection of Cerebral Blood Flow in Patients with Acute Ischemic Syndrome (2013)

Purpose: To investigate the potential clinical value and diagnostic performance of arterial spin-labeled (ASL) and dynamic susceptibility contrast (DSC) perfusion in detection of cerebral blood flow (CBF) changes before and after endovascular recanalization in patients with acute ischemic syndrome (AIS). Methods: This retrospective study was performed using MR examinations between 2010-2012. Inclusion criteria were: patients with AIS who underwent endovascular recanalization and acquisition of both ASL and DSC before and after revascularization. ASL CBF and multiparametric DSC perfusion maps were qualitatively evaluated for image quality, presence of hypo or hyperperfusion and location of perfusion abnormality. Lesion segmentation for infarct core (ADCb &gt;550) and hypoperfused area (TMax &gt; 4 sec) was performed on DSC. rCBF was calculated using a regions-of-interest (ROI) method in the infarction core and hypoperfused areas using coregistered ASL and DSC images. Core and hypoperfused rCBF ROI’s were used for paired pre- and post-treatment intermodality comparisons. Interobserver and intermodality agreement was evaluated by Kappa test. T-test and Spearman correlation coefficients were calculated for ASL and DSC rCBF values. Results: Twenty-five patients were met our inclusion criteria. Five studies were rated non-diagnostic, resulting in a total of 45 pair of DSC-ASL for comparison. ASL and DSC agreed on type of perfusion abnormality in 32 of 45 cases (71%) and location of the perfusion abnormality in 36 of 45 cases (80%). The image quality of ASL was lower than DSC, resulting in interobserver variability for the type (k =0.45) and location (k=0.56) of perfusion abnormality. ASL was unable to show any type of perfusion abnormality in 11% of patients. In patients with successful recanalization, hyperperfusion (rCBF&gt; 1) was detected in 100% on DSC and 47% on ASL. ASL showed prolonged arterial transit effects in 58% of successfully recanalized patients. Conclusion: ASL is moderately consistent with DSC for detection of cerebral blood flow changes in patients with AIS. Qualitative and quantitative differences exist between two modalities, in particular in respect to detection of hyperperfusion in successfully recanalized patients.
Multimodal Generative Models for Scalable Weakly-Supervised Learning (2018)

Multiple modalities often co-occur when describing natural phenomena. Learning a joint representation of these modalities should yield deeper and more useful representations. Previous generative approaches to multi-modal input either do not learn a joint distribution or require additional computation to handle missing data. Here, we introduce a multimodal variational autoencoder (MVAE) that uses a product-of-experts inference network and a sub-sampled training paradigm to solve the multi-modal inference problem. Notably, our model shares parameters to efficiently learn under any combination of missing modalities. We apply the MVAE on four datasets and match state-of-the-art performance using many fewer parameters. In addition, we show that the MVAE is directly applicable to weakly-supervised learning, and is robust to incomplete supervision. We then consider two case studies, one of learning image transformations---edge detection, colorization, segmentation---as a set of modalities, followed by one of machine translation between two languages. We find appealing results across this range of tasks.

Instrumental Aspects of Dynamic Two-Dimensional Infrared Spectroscopy (1993)

Dynamic two-dimensional infrared (2D IR) correlation maps are a convenient means of examining the information contained in time-resolved IR spectra. Dynamic 2D IR spectra can be collected with the use of either dispersive or Fourier transform (FT) IR spectrometers. Use of a step-scanning FT-IR spectrometer has advantages over conventional rapid-scan FT-IR spectrometry when one is acquiring time-resolved IR data on time scales faster than about 0.1 s, because the spectral multiplexing is removed from the time domain. Dynamic IR spectra of atactic polystyrene (undergoing a small-amplitude oscillatory strain) collected on both dispersive and FT instrumentation are compared. Although the dispersive approach produces higher signal-to-noise ratios over small spectral regions, the multiplex advantage makes the FT approach attractive when broader spectral coverages are required. The first vibrational circular dichroism (VCD) spectrum [of (–)- α;-pinene] collected on a step-scanning interferometer is also presented.
Cognition as Interaction (2007)

Many cognitive activities are irreducibly social, involving interaction between several different agents. We look at some examples of this in linguistic communication and games, and show how logical methods provide exact models for the relevant information flow and world change. Finally, we discuss possible connections in this arena between logico-computational approaches and experimental cognitive science.
Migraine prevention with a supraorbital transcutaneous stimulator: A randomized controlled trial (2013)

Schoenen et al.1 provided evidence that trigeminal neurostimulation with a supraorbital transcutaneous stimulator (STS) is effective for migraine. STS involves the application of electrodes and stimulator via an invasive surgical procedure that includes expensive medical consumables and possible complications. Only 70.6% of patients are very satisfied or moderately satisfied and approximately 1 out of 5 was not satisfied after STS effective neurostimulation.1 This means that 20%–30% of patients were dissatisfied with the procedure. Unfortunately, there is no way to preoperatively predict which patients will respond to the stimulation. STS has a sedative effect via a change in CNS activity.1 Acupuncture (e.g., somatic acupuncture, ear acupuncture, or electroacupuncture) has been successfully used for migraine2,3 and reduces sympathetic nerve activity.4 Based on those data, we propose that acupuncture can predict the efficacy of STS: if acupuncture is effective, STS will also be effective. For migraineurs, inexpensive and minimally invasive acupuncture can be performed before the STS. If acupuncture is efficient, STS may also be efficient and worth performing.

Global Ranking Using Continuous Conditional Random Fields (2008)

This paper studies global ranking problem by learning to rank methods. Con-ventional learning to rank methods are usually designed for ‘local ranking’, in the sense that the ranking model is defined on a single object, for example, a document in information retrieval. For many applications, this is a very loose approximation. Relations always exist between objects and it is better to define the ranking model as a function on all the objects to be ranked (i.e., the relations are also included). This paper refers to the problem as global ranking and proposes employing a Con-tinuous Conditional Random Fields (CRF) for conducting the learning task. The Continuous CRF model is defined as a conditional probability distribution over ranking scores of objects conditioned on the objects. It can naturally represent the content information of objects as well as the relation information between objects, necessary for global ranking. Taking two specific information retrieval tasks as examples, the paper shows how the Continuous CRF method can perform global ranking better than baselines. 1
Alcohol Abuse in Later Life: Issues and Interventions for Counselors (2000)

Problems in identification, diagnosis, assessment, and treatment of older abusers are reviewed. A case example illustrates the dynamics of effective treatment with this population.
Burnout in therapy radiographers in the UK (2012)

The 2007 UK National Radiotherapy Advisory Group report indicated that the number and type of staff available is one of the "rate-limiting" steps in improving productivity in radiotherapy departments. Retaining well-trained, satisfied staff is key to meeting the objectives of the report; burnout is an important factor linked to satisfaction and attrition. The results of a survey measuring burnout in a sample of radiotherapists (therapy radiographers) are presented and considered against norms for the health sector and burnout in therapists from Canada and the USA. Case study methodology was used studying six radiotherapy departments selected because of close geographical proximity and differing vacancy rates for radiotherapists. An anonymous survey of radiotherapists used the Maslach Burnout Inventory (MBI) and other workforce-related measures (e.g. job satisfaction scales, measures of professional plateau, intentions to leave, job characteristics and demographic data); the results of the burnout questionnaire alone are presented in this paper. A total of 97 completed questionnaires were returned (representing a 28% response rate). The average score for emotional exhaustion was higher than the MBI norms, with 38% of respondents reporting emotional exhaustion (an element of burnout). The data presented support and validated a previous qualitative study, and highlighted key areas of concern requiring further study. A correlation between burnout and job dissatisfaction and intention to leave was identified; managers may want to consider encouraging role extension and good leadership qualities in treatment unit leaders to minimise the potential for burnout.
Attenuation of Reflected and Transmitted Ultrasonic Waves Through a Rough Interface (1987)

The problem of ultrasonic transmission and reflection at a randomly rough interface is considered in connection with ultrasonic NDE of rough surface samples by immersion method. A simple first-order phase perturbation technique is used to calculate both transmitted and reflected components for comparison with experimental results. The transmitted wave is shown to be attenuated in a way similar to the reflected one, and their attenuation ratio is found to be independent of frequency in the considered cases of slight surface roughness. For instance, the surface roughness incuded attenuation of the wave reflected from a water-aluminum interface is about seven times higher than that of the transmitted component. Experimental results are presented to show good agreement with calculated predictions of the suggested simple technique for both sand- and shot-blasted aluminum samples with 8 to 40 pm rms roughness in the 2 to 20 MHz frequency range.
