The incidence of pancreatic septic necroses in the group with total enteral nutrition (23%) was lower than that in the group with total parenteral nutrition (72%, P < 0.05). Mortality in the total parenteral nutrition group (43%) was higher than in the total enteral nutrition group (11%, P < 0.05).\n\nConclusion: Total enteral nutrition is better than total parenteral nutrition in the prevention of pancreatic necrotic infection in severe acute pancreatitis.”
“A new approach of periodic production of dusty plasma consisting of pulsed injection of BIX 01294 hexamethyldisiloxane (HMDSO) in argon axially asymmetric
radiofrequency (RF) discharge was investigated in this work. The range of plasma operating conditions in which this dusty plasma can exist was closely examined. The obtained results clearly show that a net periodicity in the formation/disappearance of dust particles in the plasma can be maintained on a very large scale of discharge duration. The significance of discharge axial asymmetry to the dust particles behaviour in the plasma is revealed by the development of an asymmetric in shape void shifted towards the powered RF electrode. SBE-β-CD in vivo The key role of the reactive gas and its pulsed injection on each stage of the oscillating process
of formation/disappearance of dust particles is disclosed by optical and electrical measurements. It is shown that Proteasome inhibitor the period of dusty plasma formation/disappearance is inversely related to the HMDSO injection time. Moreover, the impact of time injection over short period (5 s) is examined.
It indicates the conflicting role played by the HMDSO on the reduction of dusty plasma during the reactive gas injection and the reappearance of particles in the plasma during the time off. The electronegative behavior of the plasma in the presence of negatively charged particles seems to explain the energetic modifications in the discharge. A frequency analysis of the floating potential reveals all these cyclic processes. Particularly, in the 10-200 Hz frequency range, the presence and the evolution of dust particles in the plasma over one generation can be observed. (C) 2012 American Institute of Physics.
