The popular ‘incentive salience theory’ of food reward recognises not only a hedonic/pleasure component (‘liking’) but also an incentive motivation component (‘wanting’ or ‘reward-seeking’). Central to the neurobiology of the reward mechanism is the mesoaccumbal dopamine system that confers incentive motivation not only for natural rewards such as food but also by artificial rewards (eg. addictive drugs). Indeed,

this mesoaccumbal dopamine system receives and integrates information about the incentive (rewarding) Caspase-8 Inhibitor value of foods with information about metabolic status. Problematic over-eating likely reflects a changing balance in the control exerted by hypothalamic versus reward circuits and/or

it could reflect an allostatic shift in the hedonic set point for food reward. Certainly, for obesity to DNA-PK inhibitor prevail, metabolic satiety signals such as leptin and insulin fail to regain control of appetitive brain networks, including those involved in food reward. On the other hand, metabolic control could reflect increased signalling by the stomach-derived orexigenic hormone, ghrelin. We have shown that ghrelin activates the mesoaccumbal dopamine system and that central ghrelin signalling is required for reward from both chemical drugs (eg alcohol) and also from palatable food. Future therapies for problematic over-eating and obesity may include drugs that interfere with incentive motivation, such as ghrelin antagonists.”
“Familial hypercholesterolemia is a rare disorder characterized by high cholesterol levels and early cardiovascular disease. Early detection and treatment with statins and CRT0066101 mouse other hypolipidemic agents are effective in heterozygous patients. Low-density lipoprotein

apheresis and liver transplantation are treatment options in homozygous familial hypercholesterolemia. We report a case of a 27-year-old pregnant woman with familial hypercholesterolemia who presented with breathlessness and swelling in the joints. She had been taking statins previously, which were stopped and she had been put on low-lipid and low-residue diet to reduce the risk of acute coronary event and sudden intrauterine death. She was found to have dilated cardiomyopathy with 25% ejection fraction. At 36 weeks of gestation, we carried out cesarean section in view of poor biophysical profile. Familial hypercholesterolemia is a very rare disorder with only a few cases reported in the published work during pregnancy. Statins are contraindicated during pregnancy and diet modification remains the mainstay of therapy.”
