Changes in intestinal absorption of glucose in rats treated with ethanol

Riassunto Gli Autori hanno indagato se l'intossicazione subacuta da etanolo provoca nel ratto alterazioni dell'assorbimento intestinale del glucosio. L'assorbimento intestinale del glucosio è diminuito in maniera statisticamente significativa nei ratti trattati per 2 e 7 giorni ed è risultato quasi normale in quelli trattati per 20 giorni con etanolo.     

Triglycerides and other lipid classes in human atherosclerosis

Riassunto I lipidi totali e le singole classi lipidiche sono stati determinati sul plasma di 15 soggetti normali e di 25 aterosclerotici. I lipidi totali e i trigliceridi plasmatici sono risultati, in modo statisticamente significativo, più alti nei soggetti aterosclerotici. I trigliceridi inoltre sono risultati più elevati negli aterosclerotici, anche quando erano espressi come percentuale dei lipidi totali. I trigliceridi sembrano essere la classe lipidica più significativa nella malattia aterosclerotica.     

Making Quantum Theory Compatible with Realism

After a brief account of theway quantum theory deals with naturalprocesses, the crucial problem that such atheory meets, the measurement or, better, themacro-objectification problem is discussed.The embarrassing aspects of the occurrence ofentangled states involving macroscopic systemsare analyzed in details. The famous example ofSchroedinger's cat is presented and it ispointed out how the combined interplay of thesuperposition principle and the ensuingentanglement raises some serious difficultiesin working out a satisfactory quantum worldview, agreeing with our definiteperceptions. The orthodox solution to themacro-objectification problem, i.e. thepostulate of wave packet reduction, isanalyzed and is proved to be inconsistent withthe assumption that the theory governes alsothe measurement process. After these premises,the rest of the paper is devoted to discuss arecent proposal of overcoming the difficultiesof the standard formalism by acceptingnonlinear and stochastic modifications of thequantum dynamics. The proposed theory is shownto agree with all known predictions of thestandard theory concerning microscopic systemsand to account, on the basis of a universaldynamics which is assumed to govern allnatural processes, for wave packet reductionin measurement processes and, more important,to eliminate all the difficulties concerningmacroscopic situations. Actually, the proposedtheory allows one to take consistently amacrorealistic position about natural processes and about our definite perceptions.
