The influence of a depressed scapular alignment on upper limb neural tissue mechanosensitivity and local pressure pain sensitivity
2017
A depressed scapular alignment could lead to prolonged and repetitive stress or compression of the brachial plexus, resulting in sensitization of neural tissue. However, no study has investigated the influence of alignment of the scapulae on sensitization of upper limb neural tissue in otherwise asymptomatic people. In this case-control study, we investigate the influence of a depressed scapular alignment on mechanosensitivity of the upper limb peripheral nervous system as well as pressure pain thresholds (PPT). Asymptomatic individuals with neutral vertical scapular alignment (n = 25) or depressed scapular alignment (n = 25) participated. We measured the upper limb neurodynamic test (ULNT1…
Synergy of spatial frequency and orientation bandwidth in texture segregation
2021
Defining target textures by increased bandwidths in spatial frequency and orientation, we observed strong cue combination effects in a combined texture figure detection and discrimination task. Performance for double-cue targets was better than predicted by independent processing of either cue and even better than predicted from linear cue integration. Application of a texture-processing model revealed that the oversummative cue combination effect is captured by calculating a low-level summary statistic (\(\Delta CE_m\)), which describes the differential contrast energy to target and reference textures, from multiple scales and orientations, and integrating this statistic across channels wi…
Complementary feeding and "donner les bases du goût" (providing the foundation of taste). A qualitative approach to understand weaning practices, att…
2013
http://www.sciencedirect.com/science/article/pii/S0195666313003814; International audience; Complementary feeding (CF) practices vary within and across cultures but have been investigated only to a very limited extent. It is however important to understand CF practices and how they differ, as CF sets the foundation for children's later food choices. The present study was set out to examine practices, attitudes and experiences of CF including the introduction of vegetables amongst French mothers (n = 18, 25-39 years). Thematic analysis of transcribed focus groups and interviews revealed the perceived importance of the weaning period, as a critical milestone for infants' development but with …
Multimodal Device for Real-Time Monitoring of Skin Oxygen Saturation and Microcirculation Function
2019
The present study introduces a recently developed compact hybrid device for real-time monitoring of skin oxygen saturation and temperature distribution. The prototype involves a snapshot hyperspectral camera, multi-wavelength illuminator, thermal camera, and built-in computer with custom-developed software. To validate this device in-vivo we performed upper arm vascular occlusion on eight healthy volunteers. Palm skin oxygen saturation maps were analyzed in real-time using k-means segmentation algorithm and two-layer optical diffuse model. The prototype system demonstrated a satisfying performance of skin hyperspectral measurements in the spectral range of 507&ndash
Uncertainty quantification in simulations of epidemics using polynomial chaos.
2012
Mathematical models based on ordinary differential equations are a useful tool to study the processes involved in epidemiology. Many models consider that the parameters are deterministic variables. But in practice, the transmission parameters present large variability and it is not possible to determine them exactly, and it is necessary to introduce randomness. In this paper, we present an application of the polynomial chaos approach to epidemiological mathematical models based on ordinary differential equations with random coefficients. Taking into account the variability of the transmission parameters of the model, this approach allows us to obtain an auxiliary system of differential equa…
Recognition of Root Canal Orifices in Video Sequences as a Future Support System During Endodontic Treatment
2009
Abstract Introduction The objective of this study was to show the practical application of computer-aided techniques for detecting root canal orifices through the access cavity using a video camera mounted on a microscope. Methods A minimum distance classification image recognition algorithm was tested in an in vitro study to assess the possibilities of computer-aided recognition of root canal orifices. A Motic DM143 digital stereo microscope (Motic Germany GmbH, Wetzlar, Germany) was used because it includes a video camera that can be connected via USB1.1 to any computer. Results The newly developed software is capable of communicating with a video camera and can automatically detect the r…
Control of intrauterine device insertion with three-dimensional ultrasound: is it the future?
1996
A comparative study was designed to determine whether three-dimensional transvaginal sonography (3D-TVS) offered advantages over two-dimensional transvaginal sonography (2D-TVS) for the identification and location of IUDs in 66 asymptomatic women. Hysteroscopy was performed in cases in which there was a discrepancy between the information obtained by both methods (n = 14). In eight cases (12.2%) the IUD was misidentified with 2D-TVS. In six cases (9.1%) it was not possible to identify the device model with 2D-TVS. In two cases (3.0%) 2D-TVS failed to identify the position of the device. In contrast, all IUDs were identified and located accurately with 3D-TVS. © 1996 John Wiley & Sons, Inc.
Vesico-uterine fistula treated by amenorrhoea induced with contraceptive steroids. Two case reports.
1980
2 case reports of women with vesico-uterine fistulae who were successfully treated by inducing amenorrhea by the continuous administration of an estrogen-progestogen compound for 6 months are presented. Ortho-Novum 1/50 was used. The amenorrheic condition induced by continuous ingestion of an oral contraceptive agent allowed the fistula time to heal since fistulae rarely close spontaneously because of fluids flowing fhrough them inhibiting the healing process. This method of management should be tried before surgery the generally recommended treatment.
Temporal Structure of Human Gaze Dynamics Is Invariant During Free Viewing.
2015
We investigate the dynamic structure of human gaze and present an experimental study of the frequency components of the change in gaze position over time during free viewing of computer-generated fractal images. We show that changes in gaze position are scale-invariant in time with statistical properties that are characteristic of a random walk process. We quantify and track changes in the temporal structure using a well-defined scaling parameter called the Hurst exponent, H. We find H is robust regardless of the spatial complexity generated by the fractal images. In addition, we find the Hurst exponent is invariant across all participants, including those with distinct changes to higher or…
Ventricular Tachycardia and Early Fibrillation in Patients With Brugada Syndrome and Ischemic Cardiomyopathy Show Predictable Frequency-Phase Propert…
2015
[EN] Background¿ Ventricular fibrillation (VF) has been proposed to be maintained by localized high-frequency sources. We tested whether spectral-phase analysis of the precordial ECG enabled identification of periodic activation patterns generated by such sources. Methods and Results¿Precordial ECGs were recorded from 15 ischemic cardiomyopathy and 15 Brugada syndrome (type 1 ECG) patients during induced VF and analyzed in the frequency-phase domain. Despite temporal variability, induced VF episodes lasting 19.6±7.9 s displayed distinctly high power at a common frequency (shared frequency, 5.7±1.1 Hz) in all leads about half of the time. In patients with Brugada syndrome, phase analysis of …
