Hypertrophy and ER Stress Induced by Palmitate Are Counteracted by Mango Peel and Seed Extracts in 3T3-L1 Adipocytes
2023
A diet rich in saturated fatty acids (FAs) has been correlated with metabolic dysfunction and ROS increase in the adipose tissue of obese subjects. Thus, reducing hypertrophy and oxidative stress in adipose tissue can represent a strategy to counteract obesity and obesity-related diseases. In this context, the present study showed how the peel and seed extracts of mango (Mangifera indica L.) reduced lipotoxicity induced by high doses of sodium palmitate (PA) in differentiated 3T3-L1 adipocytes. Mango peel (MPE) and mango seed (MSE) extracts significantly lowered PA-induced fat accumulation by reducing lipid droplet (LDs) and triacylglycerol (TAGs) content in adipocytes. We showed that MPE a…
On the variations of acoustic absorption peak with particle velocity in micro-perforated panels at high level of excitation.
2010
The acoustic behavior of micro-perforated panels (MPP) is studied theoretically and experimentally at high level of pressure excitation. A model based on Forcheimer's regime of flow velocity in the perforations is proposed. This model is valid at relatively high Reynolds numbers and low Mach numbers. The experimental method consists in measuring the acoustical pressure at three different positions in an impedance tube, the two measurement positions usually considered in an impedance tube and one measurement in the vicinity of the rear surface of the MPP. The impedance tube is equipped with a pressure driver instead of the usual loudspeaker and capable of delivering a high sound pressure lev…
Feasibility of using more polishable aggregates in dense-graded asphalt surface mixture: Case study of dolomite
2022
This study aimed to evaluate the feasibility of using more dolomite aggregates in asphalt surface mixtures that are typically used by West Virginia Division of Highways (WVDOH). The laboratory test results indicated that increasing dolomite content in asphalt surface mixtures resulted in a faster deterioration rate at the early polishing stage. In addition, asphalt surface mixtures containing more than 50% dolomite coarse aggregates would significantly reduce roadway safety. The field test results validated that dolomite shall not exceed 50% of coarse aggregate in asphalt surface mixture if the projected traffic volume is greater than 3.0 million equivalent single axle loads (ESALs).

La música tiene la capacidad de transmitir conocimientos, habilidades y valores intrínsecos a la cultura del compositor, y al mismo tiempo transmite emociones y sentimientos comunes a todas las culturas; por ello puede decirse que la música es un instrumento idóneo para el establecimiento de un diálogo intercultural. La acción comunicativa musical siempre ha sido objeto de análisis; aunque ha sido la falta de diálogo cultural la que ha aumentado la consideración de que la música puede posibilitar el camino hacia la adquisición de la Interculturalidad. Este artículo muestra cómo la música favorece el proceso comunicativo intercultural, al considerarse como la principal herramienta de trabajo…
Intelligent Adaptive Motion Control for Ground Wheeled Vehicles
2014
In this paper a new intelligent adaptive control is applied to solve a problem of motion control of ground vehicles with two independent wheels actuated by a differential drive. The major objective of this work is to obtain a motion control system by using a new fuzzy inference mechanism where the Lyapunov’s stability can be assured. In particular the parameters of the kinematical control law are obtained using an intelligent Fuzzy mechanism, where the properties of the Fuzzy maps have been established to have the stability above. Due to the nonlinear map of the intelligent fuzzy inference mechanism (i.e. fuzzy rules and value of the rule), the parameters above are not constant, but, time a…
Numerical simulations demonstrate that the double tapering of the spatualae of lizards and insects maximize both detachment resistance and stability
2011
Many biological attachment devices of insects, spiders and geckos consist of arrays of hairs (setae), which are terminated by contact elements of different shapes. However, the most frequently observed shape is a thin plate-like spatula. In spite of a rather wide range of sizes, most spatulae of different animals are not uniform, but rather possess a gradient in thickness and width. Here we show that the spatulae of insects and geckos become gradually thinner and wider approaching the end. This geometrical effect is explained in the present paper, by using a numerical approach for the modelling of the van der Waals adhesion and friction between the contact elements and the substrate. The ap…
Covert digital manipulation of vocal emotion alter speakers' emotional states in a congruent direction
2016
International audience; Research has shown that people often exert control over their emotions. By modulating expressions, reappraising feelings, and redirecting attention, they can regulate their emotional experience. These findings have contributed to a blurring of the traditional boundaries between cognitive and emotional processes, and it has been suggested that emotional signals are produced in a goal-directed way and monitored for errors like other intentional actions. However, this interesting possibility has never been experimentally tested. To this end, we created a digital audio platform to covertly modify the emotional tone of participants' voices while they talked in the directi…

Nurses' self-reflection via videotaping to improve communication skills in health counseling.
1999
Abstract The purpose of this qualitative research was to describe nurses' opinions of their communication skills in health counseling situations and to analyze the levels of reflectivity in their evaluations according to Mezirow. Nineteen nurses participated in the research on a voluntary basis and evaluated their interaction with patients on video on two occasions half a year apart. Nurses gave verbal feedback in an interview immediately after videotaping, after which they read education materials, watched their counseling on video and wrote an evaluation of their communication skills. Transcribed audiotaped interviews and written evaluations were analyzed using content analysis. Nurses sa…
Reflective questions in health counseling.
2000
This study explores questions that nurses ask patients in order to awaken reflection on their health behavior in health counseling. Thirty-eight counseling situations were videotaped in a hospital. The data were analyzed using conversation analysis which was adapted for the purpose of this study. Nonverbal communication supported speech and was interpreted alongside it. This study found that nurses used only a few reflective questions, most of which were future-oriented or introduced hypotheses. In a nonreflective discussion, nurses used only check-up and alternative questions to get information about patients' illnesses and health care measures. Findings indicated that reflective conversa…
