Control of feeding behavior

Control of feeding behavior involves peripheral peptides (insulin, ghrelin, leptin) plus several peptides in the CNS (orexins/hypocretins, CCK, galanin, MSH, neuropeptide Y, CRH, cocaine-and-amphetamine-regulated transcript (CART)) [35, 36]. Some of the same peptides are involved in reward systems crucial to drug addiction. Specific receptor blockers are being tested for many of these peptide-receptor systems, with the hope of very selective actins with minimal side effects [35], For example, there are two CCK receptor subtypes, CCK-A and...

Alternatively, fabric patches treated with permethrin have been evaluated against natural and laboratory strains of human body flee in Pern. Permethrin-treated fabric is toxic to flee on contact and quickly affects feeding behavior, even when washed up to 20 times. Thus permethrin-treated clothing intermpts disease transmission, and offers a passive louse control not previously feasible (39). 

The results for this test and for the responses to disturbances in feed compositions of B and C are summarized in Table 4. A consistent trend with the servo tests was observed, in the sense that one option provides the best common choice for the control of the system under feed disturbances on the extreme components of the mixture, but a different arrangement yields a superior dynamic performance for the control task under a feed disturbance on the intermediate component. From Table 4, the lAE values indicate that the PUL system shows the best behavior for feed disturbances in the light and heavy component. However, the PUL arrangement shows the worst response when the feed disturbance in the intermediate component was considered, in which case both the Petlyuk and the PUV systems show fairly similar rejection capabilities.
