Hypothalamic-pituitary-adrenal Responses to Weight Loss in Mice Following Diet Restriction, Activity or Separation Stress: Effects of Tyrosine
Despite similar weight loss in the three models there were no predictable associations between hypothalamic noradrenaline metabolism and plasma ACTH or glucocorticoid concentrations and Tyrosine might alleviate some of the different patho-physiological problems associated with the stress of weight loss.
Diet Restriction in Mice Causes a Decrease in Hippocampal Choline Uptake and Muscarinic Receptors that is Restored by Administration of Tyrosine: Interaction between Cholinergic and Adrenergic Receptors Influencing Cognitive Function
The effect of diet restriction and tyrosine appeared to be both pre- and post-synaptic, indicating modulation of cholinergic activity by adrenergic tone, and may have implications for the treatment of mood changes associated with weight loss and semi-starvation.
Protective effects of luteolin on cognitive impairments induced by psychological stress in mice
It is suggested that luteolin treatment serves as a key role in improving the psychological stress-induced cognitive impairments.
Effects of epigallocatechin-3-gallate on behavioral impairments induced by psychological stress in rats
GTPs and EGCG modulation could improve the cognitive impairments induced by psychological stress, and the related mechanisms may be involved with the changes of catecholamines, 5-hydroxytryptamine, cytokines and expressions of metallothioneins.
Histamine H3 Receptor Ligands—KSK-59 and KSK-73—Reduce Body Weight Gain in a Rat Model of Excessive Eating
The pharmacological properties of histamine H3 receptor antagonists, (4-pyridyl)piperazine derivatives, are shown as the compounds causing not only slower weight gain but also ameliorating some metabolic disorders in rats having the opportunity to overeat.
Long-Term Physiological Alterations and Recovery in a Mouse Model of Separation Associated with Time-Restricted Feeding: A Tool to Study Anorexia Nervosa Related Consequences
Interestingly, during a recovery phase, mice showed a high capacity to normalize these parameters with the exception of plasma leptin levels, and this study strongly supports the separation-based anorexia protocol as a valuable model of long-term negative energy balance state.
