Degeneration of ALF D n Metrics
نویسندگان
چکیده
Beginning with the Legendre transform construction of hyperkähler metrics, we analyze the ALF version of the D n metrics. We determine the constraint equation obtained from extremizing the w coordinate of the generating function F (z, ¯ z, u, ¯ u, w) and study its behavior as we send two of the mass parameters of the D n metric to zero. We find that the constraint equation enforces the limit that the metric becomes that of multi-Taub-NUT.

متن کاملProteomic Signature of Acute Liver Failure: From Discovery and Verification in a Pig Model to Confirmation in Humans.
Acute liver failure (ALF) is a fatal condition hallmarked by rapid development. The present study aimed to describe the dynamic alterations of serum proteins associated with ALF development, and to seek for novel biomarkers of ALF. Miniature pigs (n = 38) were employed to establish ALF models by infusing d-galactosamine (GALN, 1.3 g/kg). A total of 1310 serum proteins were compared in pooled se...
متن کاملArtificial liver support in pigs with acetaminophen-induced acute liver failure
AIM To establish a reversible porcine model of acute liver failure (ALF) and treat it with an artificial liver system. METHODS Sixteen pigs weighing 30-35 kg were chosen and administered with acetaminophen (APAP) to induce ALF. ALF pigs were then randomly assigned to either an experimental group (n = 11), in which a treatment procedure was performed, or a control group (n = 5). Treatment was ...
متن کاملDigestibility and nitrogen retention in llamas and goats fed alfalfa, C3 grass, and C4 grass hays
The objective of this experiment was to determine the relative digestive capabilities and N retention between goats and llamas fed three forages. Four llamas (2 yrs; 125± 7.3 kg BW) and four Boer-cross goats (2 yrs; 53± 8.4 kg BW) were housed in metabolism crates and fed alfalfa (Medicago sativa; ALF), temperate C3 grass (Festuca arundinacea; C3G) and tropical C4 grass (Cynodon dactylon; C4G) h...
متن کاملAcute liver failure-induced death of rats is delayed or prevented by blocking NMDA receptors in brain.
Developing procedures to delay the mechanisms of acute liver failure-induced death would increase patients' survival by allowing time for liver regeneration or to receive a liver for transplantation. Hyperammonemia is a main contributor to brain herniation and mortality in acute liver failure (ALF). Acute ammonia intoxication in rats leads to N-methyl-D-aspartate (NMDA) receptor activation in b...
