Is weight status associated with peripheral levels of oxytocin? A pilot study in healthy women.

Publication date: Available online 17 October 2019Source: Physiology &BehaviorAuthor(s): Janelle A Skinner, Manohar L Garg, Christopher V Dayas, Tracy L BurrowsABSTRACTThe neuropeptide oxytocin is best known for its role during parturition and the milk-let down reflex. Recent evidence identifies a role for oxytocin in eating behaviour. After oxytocin administration, caloric intake is reduced with stronger inhibitory effects in individuals with obesity. Whether the experience of visual food cues affects secretion or circulating levels of oxytocin is unknown. This pilot study had three aims: 1) to measure fasting appetite hormones with a focus on plasma oxytocin concentrations; 2) determine whether healthy vs. hyperpalatable visual food cues differentially altered plasma oxytocin; and 3) assess whether appetite hormone responses to healthy vs. hyperpalatable food images depended on weight or food addiction status. Eighteen healthy women of varying weight status, with/without self-reported food addiction were recruited. Study participants completed a set of standardised questionnaires, including Yale Food Addiction Scale, and attended a one-off experimental session. Blood was collected before and after viewing two sets of food images (healthy and hyperpalatable foods). Participants were randomly allocated in a crossover design to view either healthy images or hyperpalatable foods first. A positive correlation between BMI and plasma oxytocin was found (r2=0.32, p=0.021) at ba...

CONCLUSION: Dysregulated activity of EFhd2 is increasingly considered as a contributing factor for the development of numerous neurodegenerative disorders. Whether EFhd2 can be used as biomarker or in therapeutic approaches has to be addressed in future research. PMID: 31742960 [PubMed - in process]

Publication date: Available online 19 November 2019Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Allison M. Ahrens, Omar J. AhmedAbstractIndividuals differ widely in their drug-craving behaviors. One reason for these differences involves sleep. Sleep disturbances lead to an increased risk of substance use disorders and relapse in only some individuals. While animal studies have examined the impact of sleep on reward circuitry, few have addressed the role of individual differences in the effects of altered sleep. There does, however, exist a rodent model of individual differences in reward-seeking behavior: the ...

The objective of this presentation is to explore historical, scientific, interventional, and other differences between the two paradigms, so that innovators, researchers, practitioners, policy-makers, patients, end-users, and others can gain clarity with respect to both the explicit and implicit assumptions associated with brain advancement agendas of any kind. Over the course of three decades, a series of brain-centric, evolution-inspired insights have been articulated with increasing refinement, as principles of allostasis (Sterling and Eyer, 1988; Sterling, 2004, 2012, 2014). Allostasis recognizes that the role of the ...

Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroinfla...

Conclusion The relationships between the potency of 5-HT2C blockade and hypertriglyceridemia and the potency of M3 blockade and glucose intolerance were shown in clinical setting.

CONCLUSIONS: Components crucial for psychophysiological resilience are none-wandering mind (typical of ADHD-related behavior), good social coping and attachment, and good physical health. Excessive digital media use by children and adolescents appears as a major factor which may hamper the formation of sound psychophysiological resilience.
