- Sleep restriction is associated with increased morning plasma leptin concentrations, especially in womenNorah S Simpson
Department of Neurology, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA 02215, USA
Biol Res Nurs 12:47-53. 2010..We evaluated the effects of sleep restriction on leptin levels in a large, diverse sample of healthy participants, while allowing free access to food...
- Effects of sleep restriction on adiponectin levels in healthy men and womenNorah S Simpson
Department of Neurology, Beth Israel Deaconess Medical Center Harvard Medical School, 330 Brookline Ave DA 779, Boston, MA 02215, United States
Physiol Behav 101:693-8. 2010..Adiponectin is an adipocyte-derived, anti-inflammatory hormone that is related to cardiovascular disease risk. We hypothesized that sleep restriction would reduce adiponectin levels in healthy young adults...
- Altered regional blood volume in chronic cannabis smokersJennifer T Sneider
Cognitive Neuroimaging Laboratory, Brain Imaging Center, McLean Hospital, Belmont, MA 02478, USA
Exp Clin Psychopharmacol 14:422-8. 2006..It would be of interest to extend the investigation beyond 6-36 hr of abstinence from cannabis to determine whether increased CBV values persist for several weeks or eventually normalize...
- Increased amygdala fMRI activation after secretin administrationDeborah A Yurgelun-Todd
Neuroimaging Laboratory, McLean Hospital Harvard Medical School, Belmont, MA 02478 9106, USA
Exp Clin Psychopharmacol 16:191-8. 2008..The presence of increased activation of the amygdala during the viewing of fearful faces is consistent with findings from animal studies and suggests a mechanism by which secretin may modulate social behavior...
- Differences in regional blood volume during a 28-day period of abstinence in chronic cannabis smokersJennifer T Sneider
Cognitive Neuroimaging Laboratory, Brain Imaging Center, McLean Hospital, Belmont, MA 02478, United States
Eur Neuropsychopharmacol 18:612-9. 2008..These findings suggest that while CBV levels begin to normalize with continued abstinence from cannabis, specifically in frontal areas, other temporal and cerebellar brain regions show slower CBV decreases...
- Sleep loss and inflammationJanet M Mullington
Department of Neurology, Beth Israel Deaconess Medical Center and Harvard Medical School, 330 Brookline Avenue, Boston, MA 02215, USA
Best Pract Res Clin Endocrinol Metab 24:775-84. 2010..Although the mechanism of this altered inflammatory status in humans undergoing experimental sleep loss is unknown, it is likely that autonomic activation and metabolic changes play key roles...
- Lack of hippocampal volume change in long-term heavy cannabis usersGolfo K Tzilos
Cognitive Neuroimaging Laboratory, Brain Imaging Center, McLean Hospital, Harvard Medical School, Belmont, MA 02478, USA
Am J Addict 14:64-72. 2005..These findings are consistent with recent literature suggesting that cannabis use is not associated with structural changes within the brain as a whole or the hippocampus in particular...
