In just a few weeks, a near 100% increase in body mass is observed due to high levels price JNJ-7706621 of fat storage, while the duration and depth of daily hypothermia bouts increase, The effect of RSV supplementation on body mass, rest ing metabolic rate, daily body temperature variations and spontaneous food intake in the grey mouse lemur was explored to investigate of the hypothesis that RSV supplementation will affect the time courses of pre wintering fattening mechanisms in this primate.

Because previous studies on mouse lemurs have suggested that several gut hormones may be related to the pre wintering fattening phase and to the daily heterothermia expression, we also tested the effects of RSV supplementation on several gut derived peptide hormones that are involved in numerous LDN193189 臨床試験 aspects of fuel homeostasis, We measured glucagon like peptide 1, pancre atic polypeptide, peptide YY and glucose dependent insulinotropic polypeptide, Glucagon like peptide 1 and PYY were shown to decrease energy expenditure and food intake, Conversely, PP and GIP induced an increase in energy expenditure, motor activity and mobilization of fat stores, Consequently, possi ble relationships between the key parameters involved in energy balance regulation and gut hormones in grey mouse lemurs were also investigated. Results During the control week prior to RSV supplementation, the studied animals presented an average body mass gain of 6. 2 1. 3% from their initial mass, At the end of the four weeks of RSV supplementation, the body mass gain was gradually suppressed to 1. 0 0.

3%, A 13% decrease in spontaneous food intake was noted from the third week of RSV treatment, The RMR increased by 29% after four weeks of RSV treatment com pared to the control period, Total daily locomotor activity was not modified by RSV treatment, A representative profile of the weekly average of variations in Tb of one mouse lemur is represented in Figure purchase LY2228820 2A. The mouse lemurs exhibited a significant increase in their mean Tb during the diurnal phase with a gain of 1. 0 0. 3 C between the control and the fourth week of treatment, The minimal Tb value of the animals increased by 1. 5 0. 6 C between the control and the fourth week of treatment, The amplitude of the phase of daily hypo thermia was greatly reduced in response to RSV supple mentation.

On the other hand, no significant change in the mean Tb during the active nocturnal phase was found in response to RSV supplementation, No significant time course change was reported for GLP 1, PP and PYY levels. Only the GIP level was signifi cantly increased by RSV after four weeks of supplementa tion, Although trends are visible, the increased inter indi vidual variability observed during the treatment did not allow any significant conclusion to be reached.
