Network traffic measurements collected across the Internet provide very meaningful information for researchers, service providers, and other members of the Internet community [1]. On one hand, network operators may benefit from such information in their goal of ensuring the appropriate quality of service (QoS) to their customers. Indeed, the ever-increasing(More)
The purpose of this demonstration is to show the functionality of EDIV tool to manage distributed virtualization scenarios that are deployed on PASITO, a federated experimentation infrastructure created and coordinated by RedIRIS (the Spanish Research and Education Network). The demo presents the different phases a researcher would follow to create and(More)
Feeding mice an arginine-deficient diet decreased plasma concentrations of arginine, citrulline and ornithine in the females and arginine in the males, abolishing the sexual dimorphic pattern of these amino acids found in mice fed the standard diet. In addition, the restriction of dietary arginine produced a marked decrease in body and renal weights as well(More)
The antihormone RU486 (mifepristone, 11beta-(4-dimethylaminophenyl)-17beta-hydroxy-17alpha-(prop- 1-ynyl)-estra-4,9-dien-3-one) is currently used in many endocrinological studies and in clinical practice as a contraceptive agent. The results presented here indicate that the synthetic steroid RU486 may interfere in determinations of testosterone and(More)
Sexual dimorphism in potassium content was found in plasma, kidney, heart and skeletal muscle of CD1 mice. We observed that feeding mice with a K(+)-deficient diet had an uneven and gender-dependent effect on organ weight and tissue potassium concentrations. Treatment produced a marked decrease in plasma, pancreas and skeletal muscle K(+) levels in both(More)
1. The treatment of rats with glycine (2 mg/g) produced a marked decrease in the hepatic taurine content of neonate rats but not of adult rats. 2. The decrease observed in taurine concentration in the liver of newborn rats was not found in other organs, such as brain or kidney. 3. The results showed that the change in hepatic taurine concentration was dose-(More)
1. Neuronal, but not circulating catecholamines, regulate the induction of ornithine decarboxylase (ODC) by testosterone in the mouse kidney. 2. Central and peripheral catecholamine-depleting agents, such as reserpine or alpha-methyl-p-tyrosine, exerted a more pronounced effect on renal ODC than the selective agents tetrabenazine or guanethidine. 3.(More)
A substantial elevation of the excitatory neurotransmitter glutamate can be produced in the brain of 3-day old rats, either after subcutaneous injection of monosodium glutamate (4 mg/g), or by hyperthermic treatment (40 degrees C, 3 h). In the glutamate-treated animals a large increase in the GABA levels has also been observed while the elevation of this(More)
The content of free amino acids in the cerebrospinal fluid from 52 children in different age groups with febrile seizures were determined and compared to 88 age matched children without seizures. We found that the concentrations of some amino acids in CSF in the control group decreased slowly with age, reaching the concentrations found in adults at the age(More)
