Interictal Heart Rate Variability Analysis Reveals Lateralization of Cardiac Autonomic Control in Temporal Lobe Epilepsy.

2020

International audience; Purpose: The temporal lobe, a critical hub for cognition, also plays a central role in the regulation of autonomic cardiovascular functions. Lesions in this area are usually associated with abnormalities in the regulation of heart rate (HR) and blood pressure (BP). The analysis of the heart rate variability (HRV) is useful to evaluate the cardiac parasympathetic nervous system activity. This study aims at comparing HRV changes occurring in two groups of patients suffering from Temporal Lobe Epilepsy (TLE). To that aim, we evaluated patients differentiated by the right or left location of the epileptic foci. Materials and Methods: Fifty-two adult patients with a diagn…

Le rappresentazioni dell'alterità nelle cerimonie carnevalesche. Forme e funzioni

2012

Nel saggio viene riesaminata, attraverso puntuali riferimenti alla vasta letteratura sull’argomento, una specifica modalità di guardare alle “epifanie dell’alterità”, essenzialmente ma non esclusivamente “in maschera”, così come si manifestano/manifestavano all’interno delle cerimonie carnevalesche euro-mediterranee e ci si propone di misurarne l’attuale efficacia euristica. Viene riesaminato cioè un indirizzo interpretativo essenzialmente di stampo storicistico-fenomenologico, che tende a attribuire ai mascherati il ruolo di rappresentanti dei morti, variamente riproposto entro filoni di studio di lunga durata e cui lo stesso autore ha fatto costante riferimento nei suoi lavori, direttamen…

The Influence of Natural and Model Forms of Humic Acids on the Dynamic Parameters of Model Membranes

2016

Abstract In this paper the influence of humic acid concentrations extracted from Histosols (HA-A) and their model forms (HA-B) separated from humic substances commercially produced by Carl Roth GmbH + Co.KG on the dynamic properties of liposome membranes was determined. Differences in the quality of the humic acids (HA-A and HA-B) were determined by the 1HNMR and FTIR methods. Liposomes from the sonication of egg yolk lecithin (EYL) in an aqueous solution and synthetic Dipalmitoylphosphatidylcholine (DPPC) were used. Fluidity of liposome membranes was determined by the EPR technique with spin probes (TEMPO, 16DOIXYL). The electrical parameters of membranes were found using a Keithley 6517 e…

Characterization of 1-aminocyclopropane-1-carboxylic acid oxidase from barley (Hordeum vulgare L.) seedlings and pine (Pinus sylvestris L.) needles

1999

Abstract Biochemical characteristics of 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase extracted from barley ( Hordeum vulgare L.) leaves and pine ( Pinus sylvestris L.) needles were investigated. ACC oxidase from barley leaves was soluble while for complete recovery of ACC oxidase from pine needles addition of Triton X-100 to extraction medium was necessary. The enzyme required Fe 2+ , ascorbate and NaHCO 3 for maximum activity. A non-linear time course of ACC oxidase reaction indicated possible catalytic inactivation of the enzyme. The maximum activity was measured at pH 7.0–7.2 for ACC oxidase from both barley leaves and pine needles. The apparent K m for ACC was found to be 77 and …

Research on the Diurnal Courses of Abscissic Acid, 1-Aminocyclopropane Carboxylic Acid and Its Malonyl Conjugate Contents in Needles of Damaged and U…

1993

Ethylene regulates many aspects of plant growth, development and senescence. The immediate precursor of ethylene was identified as 1-aminocyclopropane carboxylic acid (ACC) [7]. Amrhein et al. [1] discovered that ACC supplied exogenously was efficiently converted into ACC malonyl conjugate (MACC) along with ethylene production.

Studies on the diurnal courses of the contents of abscisic acid, 1-aminocyclopropane carboxylic acid and its malonyl conjugate in needles of damaged …

1993

Summary The diurnal courses of the contents of 1-aminocyclopropane carboxylic acid (ACC), its malonyl conjugate (MACC) and abscisic acid (ABA) in the two-year-old needles of damaged and undamaged spruce trees (Picea abies L.) were investigated. The contents of ACC and MACC were significantly higher in the needles of the damaged trees as compared with the undamaged ones. In the needles of the damaged spruce trees, the ACC and MACC contents, and ABA contents as well, fluctuated to a greater extent than those in the undamaged spruce trees during the day. The relationships between ACC-ABA and MACC-ACC contents as well are also discussed.
