Viral Infection Drives the Regulation of Feeding Behavior Related Genes in .

The feeding behavior in fish is a complex activity that relies on the ability of the brain to integrate multiple signals to produce appropriate responses in terms of food intake, energy expenditure, and metabolic activity. Upon stress cues including viral infection or mediators such as the proinflammatory cytokines, prostaglandins, and cortisol, both Pomc and Npy/Agrp neurons from the hypothalamus are stimulated, thus triggering a response that controls both energy storage and expenditure. However, how appetite modulators or neuro-immune cues link pathogenesis and energy homeostasis in fish remains poorly understood.

[Hepatic resection in localized Caroli disease].

Caroli disease is a cystic congenital malformation of the intrahepatic biliary tract, frequently associated with lithiasis. Commonly, cystic dilatations are bilateral and infrequently they affect only one hepatic lobule or segment. We report six patients with localized Caroli disease, three in the right and three in the left hepatic lobule, that were subjected to a hepatic resection.
