Changing the light schedule in late pregnancy alters birth timing in mice

Amano, Tomoko ; Ripperger, Jürgen A. ; Albrecht, Urs

In: Theriogenology, 2020, vol. 154, p. 212–222

In rats, birth timing is affected by changes in the light schedule until the middle of the pregnancy period. This phenomenon can be used to control birth timing in the animal industry and/or clinical fields. However, changes in the light schedule until the middle of the pregnancy period can damage the fetus by affecting the development of the major organs. Thus, we compared birth timing in...

Food vs money? Effects of hunger on mood and behavioral reactivity to reward in anorexia nervosa

Piccolo, Mayron ; Milos, Gabriella ; Bluemel, Sena ; Schumacher, Sonja ; Müller-Pfeiffer, Christoph ; Fried, Michael ; Ernst, Monique ; Martin-Soelch, Chantal

In: Appetite, 2019, vol. 134, p. 26-33

BACKGROUND: Previous studies using neuroimaging and behavioral measures reported altered reward processing in anorexia nervosa (AN). In addition, anhedonia states are frequently reported in AN, potentially due to the physiological stress produced by the permanent starvation. We investigated the effect of fasting and satiety on mood and reaction times to monetary rewards in AN patients and healthy...

Altered circulating endocannabinoids in anorexia nervosa during acute and weight‐restored phases: A pilot study

Piccolo, Mayron ; Claussen, Malte Cristian ; Bluemel, Sena ; Schumacher, Sonja ; Cronin, Annette ; Fried, Michael ; Goetze, Oliver ; Martin‐Soelch, Chantal ; Milos, Gabriella

In: European Eating Disorders Review, 2020, vol. 28, no. 1, p. 46-54

Anorexia nervosa (AN) is an eating disorder characterized by a low food intake and often exceeding exercise, leading to a particularly low body × weight proportion. Patients with AN usually report less hunger than healthy controls. Endogenous endocannabinoids (eCBs), specifically the anandamide, have been associated to hunger, as a meal initiator, but research regarding AN and eCB and...

Physiological and Molecular Responses to Altered Sodium Intake in Rat Pregnancy

Eisele, Nicole ; Klossner, Rahel ; Escher, Geneviève ; Rudloff, Stefan ; Larionov, Alexey ; Theilig, Franziska ; Mohaupt, Markus G. ; Mistry, Hiten D. ; Gennari‐Moser, Carine

In: Journal of the American Heart Association, 2018, p. -

In pregnancy, a high plasma volume maintains uteroplacental perfusion and prevents placental ischemia, a condition linked to elevated maternal blood pressure (BP). Reducing BP by increasing Na+ intake via plasma volume expansion appears contra‐ intuitive. We hypothesize that an appropriate Na+ intake in pregnancy reduces maternal BP and adapts the renin‐angiotensin system in a...

Impact of physical activity on energy balance, food intake and choice in normal weight and obese children in the setting of acute social stress : a randomized controlled trial

Horsch, Antje ; Wobmann, Marion ; Kriemler, Susi ; Munsch, Simone ; Borloz, Sylvie ; Balz, Alexandra ; Marques-Vidal, Pedro ; Borghini, Ayala ; Puder, Jardena J.

In: BMC Pediatrics, 2015, vol. 15, no. 12, p. 1-10

Background: Psychological stress negatively influences food intake and food choices, thereby contributing to the development of childhood obesity. Physical activity can also moderate eating behavior and influence calorie intake. However, it is unknown if acute physical activity influences food intake and overall energy balance after acute stress exposure in children. We therefore investigated the...
