Role of P‐glycoprotein‐mediated secretion in absorptive drug permeabiity: An approach using passive membrane permeability and affinity to P‐glycoprot…

1999

Abstract It has been shown in vivo and in vitro that P‐glycoprotein (P‐gp) may be able to influence the permeability of its substrates across biological membranes. However, the quantitative contribution of the secretion process mediated by P‐gp on the overall permeability of membranes has not been determined yet. In particular, observations need to be clarified in which substrates showing high affinity to P‐glycoprotein, e.g., verapamil, apparently do not seem to be greatly influenced by P‐gp in their permeability and consequently also with respect to their extent of GI‐absorption after oral administration, whereas weaker substrates of P‐gp, e.g., talinolol, have clearly shown P‐gp‐related …

La détermination passive et quelques thématisations particulières en anglais médical

1997

À partir d’exemples caractéristiques issus d’un corpus de 2 115 structures passives tirées de la revue britannique The Lancet, j’ai réalisé une classification originale de ces diathèses passives en trois grandes catégories, à savoir la détermination passive simple, la détermination passive complexe et la détermination passive tronquée. Après avoir précisé en quoi ces opérations de détermination correspondaient à une stratégie énonciative particulière — qu’elle soit réfléchie ou spontanée — mise en œuvre par les médecins, j’ai analysé quelques formes extrêmes, ou déterminations particulières, notamment celles présentées sous la forme d’adjectifs composés. Thanks to 2,115 passive structures c…

Reproducibility of Rolandic beta rhythm modulation in MEG and EEG

2022

The Rolandic beta rhythm, at ∼20 Hz, is generated in the somatosensory and motor cortices and is modulated by motor activity and sensory stimuli, causing a short lasting suppression that is followed by a rebound of the beta rhythm. The rebound reflects inhibitory changes in the primary sensorimotor (SMI) cortex, and thus it has been used as a biomarker to follow the recovery of patients with acute stroke. The longitudinal stability of beta rhythm modulation is a prerequisite for its use in long-term follow-ups. We quantified the reproducibility of beta rhythm modulation in healthy subjects in a 1-year-longitudinal study both for MEG and EEG at T0, 1 month (T1-month, n = 8) and 1 year (T1-ye…

Ozone-Based Atomic Layer Deposition of Al2O3 from Dimethylaluminum Chloride and Its Impact on Silicon Surface Passivation

2017

Dimethylaluminum chloride (DMACl) as an aluminum source has shown promising potential to replace more expensive and commonly used trimethylaluminum in the semiconductor industry for atomic layer deposited (ALD) thin films. Here, the Al2O3 DMACl-process is modified by replacing the common ALD oxidant, water, by ozone that offers several benefits including shorter purge time, layer-by-layer growth, and improved film adhesion. It is shown that the introduction of the ozone instead of water increases carbon and chlorine content in the Al2O3, while long ozone pulses increase the amount of interfacial hydrogen at silicon surface. These are found to be beneficial effects regarding the surface pass…

Human Activity Signatures Captured under Different Directions Using SISO and MIMO Radar Systems

2022

In this paper, we highlight and resolve the shortcomings of single-input single-output (SISO) millimeter wave (mm-Wave) radar systems for human activity recognition (HAR). A 2×2 distributed multiple-input multiple-output (MIMO) radar framework is presented to capture human activity signatures under realistic conditions in indoor environments. We propose to distribute the two pairs of collocated transmitter–receiver antennas in order to illuminate the indoor environment from different perspectives. For the proposed MIMO system, we measure the time-variant (TV) radial velocity distribution and TV mean radial velocity to observe the signatures of human activities. We deploy the Anc…

Les miraculés a bierność edukacyjna i zawodowa młodych mieszkańców wsi - case study Polska i kraje UE

2018

Poziom wykształcenia jako składnik kompetencji może odgrywać ważną rolę w określaniu szans społecznego i materialnego sukcesu, jak i w podnoszeniu jakości życia jednostek i społeczeństw, tworząc odpowiednie warunki wzrostu gospodarczego. Znajduje to odzwierciedlenie zarówno w dokumentach strategicznych Unii Europejskiej, jak i poszczególnych państw członkowskich, stając się tematem debaty publicznej. Celem artykułu jest przedstawienie skali zjawiska bierności zawodowej i edukacyjnej młodzieży w wieku 15-34 lata w Polsce i w UE (młodzież NEET), w szczególności społeczności wiejskiej, w kontekście opinii mieszkańców wsi na temat wpływu wykształcenia na ich sytuację oraz oczekiwań w zakresie w…

Natural Laboratories for Field Observation About Genesis and Landscape Effects of Palaeo-Earthquakes: a Proposal for the Rocca Busambra and Monte Bar…

2018

Earthquakes are phenomena that are still being learned by the scientific community, and poorly known, especially as regards the prevention, by the population. Having a more complete knowledge is a basic step in understanding the vastness and intensity of the destructive phenomenon that involves a great amount of people. The recent earthquakes occurred in Central Italy (L’Aquila and Amatrice earthquakes) are examples that demonstrate the importance of having knowledge about these phenomena to contrast their destructive effects. We present a geological field trip to recognise causes and landscape effects of palaeo-earthquakes recorded in the Mesozoic rock successions outcropping in Sicily. Th…
