Potential in vitro antioxidant, anti-inflammatory, antidiabetic, and anticancer effect of arachidonic acid-elicited basil leaves

2017

Abstract The study presents the impact of elicitation of basil with 0.01 µM (AA1), 1 µM (AA2) and 100 µM (AA3) arachidonic acid on the content and bioactivity of potentially bioavailable polyphenols. Elevated levels of phenolic compounds correlated with increased biological activity were observed in the extracts from basil (control and elicited) subjected to simulated gastrointestinal digestion in comparison to chemical and standard buffer extracts. Elicitation with AA1 and AA2 resulted in an 3-fold and more than 4-fold increase in the content of potentially bioavailable rosmarinic acid, respectively. In some cases, elicitation with arachidonic acid improved the pro-health properties of the…

National audience; Le XXe Siècle a été le théâtre d’importantes mutations en matière de développement urbain. A la ville pédestre, millénaire, aura succédé sur un temps très court la ville étendue à ses faubourgs desservis par les transports en commun, puis la ville périurbaine, diffuse, parfois lointaine et zonée fonctionnellement, autorisée particulièrement par la démocratisation de l’automobile (Mumford, 1964 ; Wiel, 1999). Ville et mobilité faisant système, les révolutions récentes de l’offre de mobilité ont bouleversé les formes du développement urbain, consacrant notamment la dépendance automobile (Dupuy, 1999).

Matrix-isolation and ab initio study of the complex between formic acid and xenon

2012

Abstract We report on the identification of the complexes of formic acid (FA) and Xe in an argon matrix. The geometries, interaction energies, reaction barriers, and vibrational spectra of the FA⋯Xe complexes are calculated at the MP2 level of theory. The calculations reveal four structures for the trans-FA⋯Xe complex and four structures for the cis-FA⋯Xe complex. In the experiments, two structures of the trans-FA⋯Xe complex are observed after deposition of FA/Xe/Ar matrices, with and without OH⋯Xe interaction (H-bonded and non-H-bonded structures). The cis-FA⋯Xe complex was synthesized by vibrational excitation of the non-H-bonded trans-FA⋯Xe complex. The non-H-bonded and H-bonded structur…

Measurements of transition probabilities for two N I infrared transitions and their application for diagnostics of low temperature plasmas

2010

Abstract Spectra emitted from a wall-stabilized arc, running in a gas mixture of helium, argon, nitrogen, oxygen and traces of hydrogen have been studied. Intensities of selected spectral transitions of neutral nitrogen and oxygen have been measured. Applying the Boltzmann plot method and using a reliable set of O I transition probabilities of spectral lines, originating from levels considerably spread in excitation energies, the temperatures of arc plasmas have been determined. Line intensities of two N I infrared transitions, originating from doubly excited terms 3p′ 2 F o and 3p′ 2 G have been measured. In order to obtain the corresponding transition probabilities ( A ki ) for these line…

Access to Gamma-ray Spectroscopy of Neutron-Rich sdfp Shell Nuclei

2000

γ-rays in neutron-rich sdfp shell nuclei, produced in deep-inelastic processes during collisions of 37Cl and 40Ar ions on 208Pb and of 48Ca ions on 48Ca, have been studied using large Ge multidetector arrays. Candidates for new yrast states in heavy argon and sulfur isotopes have been identified.

Phonon coupling of non-bridging oxygen hole center with the silica environment: Temperature dependence of the 1.9 eV emission spectra

2008

Abstract We report an experimental study on the shape of the 1.9 eV emission associated with non-bridging oxygen hole centers in silica and its temperature dependence, from 4 up to 300 K, under visible and ultraviolet excitation. Our analysis points out that these defects are coupled with their environment by phonons whose contribution can be described by the single mode of mean frequency between 300–400 cm −1 and Huang–Rhys factor of ∼3. On increasing the temperature, the luminescence intensity undergoes a thermal quenching caused by non-radiative processes, its deviation from a pure Arrhenius law can be accounted for by an uniform distribution of activation energy, from 0.002 to 0.05 eV. …

Artificial ventilation for basic life support leads to hyperventilation in first aid providers.

2003

The 'Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care - International Consensus on Science' recommend an artificial ventilation volume of 10 ml/kg bodyweight (equivalent to a tidal volume of 700-1000 ml) without the use of supplemental oxygen in adults with respiratory arrest. For first aid providers using the mouth-to-mouth or mouth-to-nose-ventilation technique, respectively, a ventilation volume of approximately 9.6 l/min results. Additionally, a deep breath is recommended before each ventilation to increase the end-expiratory oxygen concentration of the air exhaled by the first aid provider. To investigate the effects of these recommendations in health…

Dynamic computed tomography: a novel technique to study lung aeration and atelectasis formation during experimental CPR

2002

Objective: To develop an image based technique to study the effect of different ventilatory strategies on lung ventilation and alveolar recruitment during cardiopulmonary resuscitation (CPR). Design: (1) Technical development of the following components: (a) construction of an external chest compression device, which does not interfere with CT imaging, and (b) development of a software tool to detect lung parenchyma automatically and to calculate radiological density parameters. (2) Feasibility studies: three strategies of CPR ventilation were performed and imaged in one animal each (pigs, 25 kg): volume-constant ventilation (VCV), no ventilation, or continuous airway pressure (CPAP). One m…

Effektivit�t pr�klinischer Notfallversorgung Fiktion oder Fakt?

1996

The current increase in the cost of health care must be considered as a severe threat to the prehospital emergency services system. Two examples have been selected--the patient with polytrauma and the patient in cardiac arrest--to demonstrate the dilemma between a need for objective data and the requirements of emergency patients. Study results obtained in trauma patients indicating that total prehospital time, including scene time, is correlated to patient outcome have led to the conclusion that at the scene treatment by emergency physicians may be dispensable. It has, however also been demonstrated that the time required for medical treatment at the scene is equivalent to 20% of the total…
