Ruminal fermentation and fill change with season in an Arctic grazer: responses to hyperphagia and hypophagia
in muskoxen (Ovibos moschatus).
2001) Genetic ablation of orexin neurons in mice results in narcolepsy, hypophagia
, and obesity.
Therefore the present study was conducted to find out if lesion of septum decreases food intake and also to find out if this lesion alters hypophagia
induced by opioid antagonist naloxone which may normally act through septal opioid receptors along with through the opioid receptors in other areas of CNS.
Evidence of both hyper and hypophagia
leading to derangements in body weight during depression provides a conceptual understanding of leptin involvement in stress related behavioral changes [9,10, 11].
The animals are characterized by presenting normal or hypophagia
, reduced body growth, massive accumulation of fat and hyperinsulinemia, gradually developing to insulin resistance (DOLNIKOFF et al.
What is most interesting is that in animal models, damage to the ventromedial hypothalamus (VMH) leads to hyperphagia and increased appetite, while damage to the lateral hypothalamus (LH) causes hypophagia
and decreased appetite (Liu & Gold 2003).
Among the topics are grooming behavior, marble burying and burrowing, ultrasonic vocalizations by infant mice as a ethological expression of separation anxiety, the tail-suspension test as a model for characterizing antidepressant activity, learned helplessness, novelty-induced hypophagia
, stress protocols and behavioral testing for acute and chronic social defeat, and mice models for the manic pole of bipolar disorder.
Dr Shashi Bala Singh has immensely contributed to the understanding of high altitude physiology and pioneered the development of nutraceuticals and prophylactics for several high altitude maladies that include hypophagia
and cognitive impairment.
in rats switched from high-fat diets with different fatty-acid pattern to a high-carbohydrate diet.
Prenatal dexamethasone exposure in rats: Effects of dose, age at exposure, and drug-induced hypophagia
on malformations and fetal organ weights.
For both species, these estimates represent the end of the growing season, prior to rut and associated hypophagia
(Miquelle 1990) and before the animals enter a negative energy balance.
the remainder of the year; the states of Season-3 correspond to the main hibernation exclusive of late denning classes, active-season hypophagia
(the period of little feeding activity) and hyperphagia (the period of heightened feeding activity); and the states of Season-4 correspond to the core period of hibernation, the period of foraging on ungulate carcasses (including hibernation of females with cubs of the year), the hiatus between carcass and pine seed availability, and the period of foraging on pine seeds (Table 2; see Judd et al.
