Photoperiodic regulation of body mass, food intake, and reproduction in meadow voles
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1983Adult male voles were maintained for 10 wk in long or short photoperiods (14 or 10 h of light/day). A third group of animals housed in the long photoperiod was implanted with capsules containing melatonin. Body weight and food intake were measured weekly; various tissues were weighed and analyzed at the time of autopsy. After 10 wk, voles in the short

Regulation of body fat mass by the gut microbiota: Possible mediation by the brain
Peptides, 2016New insight suggests gut microbiota as a component in energy balance. However, the underlying mechanisms by which gut microbiota can impact metabolic regulation is unclear. A recent study from our lab shows, for the first time, a link between gut microbiota and energy balance circuitries in the hypothalamus and brainstem. In this article we will review

Towards an Understanding of Physiological Body Mass Regulation: Seasonal Animal Models
Nutritional Neuroscience, 2000This review is based around a number of interlinked hypotheses that can be summarised as follows: (i) mammalian body mass is regulated, (ii) the mechanisms that effect this regulation are common to all mammalian species, including humans, (iii) the neurochemical substrates involved in long term body mass regulation and in determining the level of body ...

Body mass regulation and the daily singing routines of European robins
Animal Behaviour, 2002Stochastic dynamic programming (SDP) models of daily singing and foraging routines in birds relate an individual's fat reserves to the relative costs and benefits of singing and foraging at different times of day. Two central predictions of such models are that: (1) overnight loss of fat reserves is higher on colder nights, and (2) birds sing more at ...

Regulation of lateral position of body centre of mass in standing balance
Physiotherapy Theory and Practice, 1992On average, normal adults stand with a nearly symmetric distribution of body weight between the legs, although there is a wide range of individual differences. In the static case, the symmetric distribution of weight implies a position for the centre of body mass (CM) that would maximise stability in the face of random, laterally directed ...

Food intake, feeding rhythm, and body mass regulation in Svalbard rock ptarmigan
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1986Food intake (FI), feeding activity (FA), and body mass (BM) were recorded continuously throughout a 13-mo period in Svalbard rock ptarmigan kept under natural conditions of light and ambient temperature at Svalbard (79 degrees N). FI was persistently high from March until August, including the period when daylight is continuous, whereas it was low ...

Functional Ecology, 1997
1. The adaptive mass‐regulation hypothesis suggests that birds should respond to worsening or unpredictable foraging conditions by increasing body mass and energetic reserves. However, previous work on adult European Starlings, Sturnus vulgaris L., has revealed that the response to worsening foraging conditions varies according to the seasonal status ...

Hypothalamic digoxin and regulation of body mass index.
Neurology India, 2003The hypothalamus produces digoxin, an endogenous membrane Na+-K+ ATPase inhibitor and regulator of neurotransmission. Digoxin being a steroidal glycoside, is synthesised by the isoprenoid pathway. In view of the reports of elevated digoxin levels in metabolic syndrome X with high body mass index, the isoprenoid pathway mediated biochemical cascade was ...

Prenatal exercise regulates influence of parental body mass index on birth outcomes
Early Human DevelopmentOffspring body mass index is often higher in parents with overweight or obesity, thereby increasing the risk of obesity later in life. As data has shown that exercise during pregnancy reduces gestational weight gain and offspring adiposity, we believe the intergenerational risk of obesity could be reduced.This study aimed to test the influence of ...
