Effects of severe arterial hypocapnia on regional blood flow regulation, tissuePO2 and metabolism in the brain cortex of cats
1981
The effect of a stepwise decrease in PaCO2 from 3.9-1.6 kPa on rCBF, rCMRO2, tissue PO2 and concentrations of glucose, lactate, pyruvate, ATP, ADP, AMP and phosphocreatine in the brain cortex was studied in cats lightly anaesthetized with sodium pentobarbital. 1. Moderate lowering of PaCO2 to 2.5 kPa induced in all animals a homogeneous decrease of rCBF in corresponding areas of the right and left hemisphere. Mean rCBF fell from 129.2 to 103.1 ml X 100 g-1 X min-1, while rCMRO2 remained unchanged (12.7-12.9 ml X 100 g-1 X min-1). The tissue PO2 frequency histograms showed a shift to lower values without indicating the presence of brain tissue hypoxia. 2. Severe arterial hypocapnia (PaCO2 = …
Die dynamische 31-Phosphor-Magnetresonanz-Spektroskopie des M. quadriceps: Einfluß von Geschlecht und Alter auf spektroskopische Parameter
1999
PURPOSE 31P-MRS is used to assess the influence of sex und age on quadriceps muscle metabolism before and after exercise. MATERIALS AND METHODS 32 healthy volunteers (15 women, 17 men, mean age: 38 +/- 17 yrs.) were examined by dynamic phosphorus-31 (31P) magnetic resonance spectroscopy (MRS). In the magnet, the quadriceps muscle was stressed by an isometric und an isotonic form of exercise until exhaustion, respectively. RESULTS Resting conditions: With increasing subjects' age, the ratio beta-adenosine triphosphate/total phosphate decreased (r = -0.37; p = 0.02). With increasing subjects' age, the ratios inorganic phosphate/phosphocreatine (r = 0.79; p = 5 x 10(-8), phosphomonoester/beta-…
Il sistema di offerta delle organizzazioni di microfinanza nei paesi in via di sviluppo: una prospettiva di sostenibilità economico-finanziaria
2007
Microfinance has evolved as an economic development approach intended to benefit low-income people. The term refers to the provision of financial services to low-income clients. The first section of this paper describes the role of microfinance sustainability as a necessary precondition for the stability and permanence of the financial system. Sustainable microfinance models demonstrate that formal institutions can deliver services profitably at the local level, challenging the assumption that subsidies are required for microfinance in developing countries. The second section aims to analyse the categories of products and services provided by microfinance institutions. A commercial approach…
Subaerālās atsegšanās notikumu pazīmes un veidojumi devona slāņkopā Latvijā
2015
Promocijas darba mērķis ir identificēt subaerālās atsegšanās notikumus devona periodā Latvijas teritorijā un noskaidrot ģeoloģiskos apstākļus un procesus, kas bija raksturīgi šiem notikumiem. Detalizēti pētīti Živetas stāva Burtnieku svītas, Franas stāva Amatas svītas un Famenas stāva Šķerveļa svītas Nīkrāces ridas nogulumi. Pētījuma pamatā ir dolokrētu paveidu nodalīšana un veidošanās apstākļu interpretācija, pamatojoties uz to struktūru un tekstūru, minerālā sastāva, it īpaši māla minerālu pētījumiem, ģeoķīmisko, t. sk. O un C stabilo izotopu analīzi, kā arī pētījumiem SEM. Ir diskutēts par abiogēnu morfoloģisko pazīmju izmantošanu subaerālās atsegšanās apstākļu identifikācijā, par pētīto…
PRIVACY E PROCREAZIONE MEDICALMENTE ASSISTITA: UNA INDAGINE COMPARATISTICA
2008
Lo studio del tema della procreazione assistita in chiave comparatistica apre nuove prospettive di ricerca, impensabili senza il confronto tra ordinamenti diversi. Ferma restando la diversità delle culture di appartenenza di ciascun sistema giuridico, appare sempre più opportuno — specie in materie di elevata rilevanza personale e sociale come quella qui trattata — valutare l'impatto e l'esito di istituti già in uso in altri ordinamenti, al fine di prevederne la possibile applicazione nel nostro ordinamento. Quello della riservatezza, ad esempio, costituisce un tema con una grande tradizione nel sistema anglo-americano, a noi ancora poco noto. Lo studio condotto ha mostrato l'elevato grado …

La volontà e il corpo
2019
Il volume affronta il tema del ruolo della volontà individuale nelle decisioni che riguardano, in senso ampio, il corpo umano. In particolare il principio di autodeterminazione, quale epifania del più ampio concetto di dignità personale, è posto a raffronto con le disposizioni in tema di trattamento sanitario – anche in riferimento alle prescrizioni anticipate di cura di cui alla l. n. 219/2017 – e con le scelte, assai complesse e dense di implicazioni sociali, sul termine della vita. La trattazione prosegue con l’esame della natura e della latitudine del consenso al prelievo di organi e tessuti da cadavere, per concludersi con l’analisi del ruolo della volontà nella procreazione, in quelle…
Cybernetics of Value Cocreation for Product Development
2017
In marketing theory, the shift from the paradigm of value creation to value ‘cocreation’ calls for a deeper grasp of the interactions between producers and customers. Marketing studies have widely focused on the value cocreation concept, but so far, the mechanism through which consumers can be involved in the process of value cocreation through product development had found little space in marketing studies. In this theoretical paper, we aim to fill this gap and pave the way towards a better understanding of the mechanisms of value cocreation for product development through second-order cybernetics. We conceive the market arena as a physical or virtual place where communications of value pro…

Efficacy of the support in medically-assisted procreation: an inter-institutional path
2020
The study refers to a research project related to PhD course in “Health Promotion and Cognitive Sciences”, Department of Psychological, Educational Sciences and Human Movement of the University of Palermo. In particular, this research focuses on one specific supportive care treatment direct to parents who are facing pregnancy at risk also of preterm birth, in a longitudinal perspective (from prenatal to neonatal). The study, which is currently in a start-up phase, will involve 100 couples recruited from a Medically Assisted Procreation Service which are at risk of preterm birth and/or which are living a diagnosis of foetal malformations or genetic syndromes. These conditions, once considere…
