Maternal Resveratrol Intake During Pregnancy and Lactation Modulates the Long-term Metabolic Effects of Maternal Nutrition on Offspring Depending on the Sex and Diet

Ros-Perez Purificacion , Diaz Francisca , Freire Alejandra , Argente-Arizon Pilar , Argente Jesus , A. Chowen Julie

Maternal nutrition can have significant long-term consequences on energy homeostasis in the offspring. However, whether resveratrol, with antioxidant and anti-obesity actions, can improve the impact of poor maternal nutrition on offspring metabolism remains largely unknown. We hypothesized that resveratrol intake by dams would protect the offspring against the harmful effects of a maternal high fat diet (HFD). We also determined if resveratrol’s effects are diet and sex d...

Palmitic Acid Could Modify Cognitive and Behavioural Functions Through Sex Specific Activation of Hippocampal Astrocytes

Frago Laura M , Freire-Regatillo Alejandra , Argente-Arizon Pilar , Argente Jesus , Chowen Julie A

Background: Prolonged poor dietary habits can result in hypothalamic inflammation and gliosis with more recent studies suggest that other brain areas may also be affected. Western or high fat diet intake has been associated with increased cognitive impairment and aberrant feeding behavior, with males and females being differentially affected. The hippocampus participates in both of these functions. Saturated free fatty acids can induce astrocyte inflammation and this could pot...

Neonatal Overnutrition Causes Sex and Age Dependant Long-Term Effects on Body Weight, Body Composition and Serum Triglyceride and Free Fatty Acid Levels

Argente-Arizon Pilar , Diaz Francisca , Fuente-Martin Esther , Chowen Julie Ann , Argente Jesus

Background: Neonatal over-nutrition (NON) can increase the propensity to become overweight and develop associated metabolic disturbances in later life. Moreover, some of these long-term effects are sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and triglyceride (TG) and non-esterified fatty acids (NEFA) levels. We hypothesized that the effects would be both age and sex dependant.<...

Free Fatty Acids Activate Hypothalamic Astrocytes in a Sexually Dimorphic Manner

Argente-Arizon Pilar , Fuente-Martin Esther , Diaz Francisca , Freire-Regatillo Alejandra , Argente Jesus , Chowen Julie A

Introduction: Obesity is known to associate with chronic systemic inflammation. However, hypothalamic inflammation also occurs in response to high fat diet (HFD)-induced obesity and is proposed to participate in central insulin/leptin resistance and the perpetuation of weight gain and systemic affectation. The weight gain and central responses to HFD differ between males and females. As hypothalamic glial cells are implicated in the central inflammatory response we hypothesize...

Long-Term Effects of Neonatal Over-Nutrition on Metabolic Equilibrium are Age and Sex Dependant

Argente-Arizon Pilar , Ros Purificacion , Diaz Francisca , Fuente-Martin Esther , Barrios Vicente , Chowen Julie A , Argente Jesus

Background: Neonatal over-nutrition (NON) can have a long-term effects on energy homeostasis and some of these effects may be sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and cytokine levels throughout development and if these changes are sexually dimorphic. We hypothesised that the effects would be both age and sex dependant.Methods: At birth, Wistar rats wer...

Being Overweight During the Peripubertal Period Modifies the Leptin Induced Changes in Hypothalamic Neuropeptides Involved in Metabolism but not those Involved in Pubertal Onset

Castro-Gonzalez David , Fuente-Martin Esther , Sanchez-Garrido Miguel A , Argente-Arizon Pilar , Tena-Sempere Manuel , Chowen Julie A , Argente Jesus

Background: Leptin is suggested to be a permissive factor in the onset of puberty by signaling at the level of the hypothalamus to indicate adequate energy stores. Overweight female rats due to increased neonatal nutrition have been shown to develop puberty before normal weight rats.Objective and hypothesis: We hypothesized that this permissive effect may be due not only to increased leptin levels, but also to increased hypothalamic sensitivity to this h...

Inflammation associated to body composition in European prepubertal children: Results from the IDEFICS study

Argente Pilar , Esther Gonzalez , Intemann Timm , Moreno Luis , Molnar Denes , Kaprio Jaakko , Russo Paola ,

Background: Obesity is characterised by excessive fat accumulation coursing with a chronic mild inflammatory state, with adipose tissue (AT) being the main site of increased systemic cytokine production. Increased adiposity early in life is the main risk factor for cardiometabolic disorders later in life, with the abnormal accumulation of lipids in AT leading to the production of pro-inflammatory cytokines. Inflammatory process that involves metabolic and card...

Sex Differences in the Pubertal Response to High-Fat Diet

Background: It is well known that ingestion of a high fat diet (HFD) can induce rapid weight gain and metabolic imbalances. However, males and females are not equally susceptible to these effects. Furthermore, an individual may be more prone to gain weight during specific developmental periods.Aims and objectives: We aimed to analyse the response to the acute exposure to a HFD during pubertal/adolescent period and to determine whether males and females r...

Novel Insights into Genetic Disorders of Growth

Argente Jesús

Human growth is a very complex phenomenon that is influenced by genetic, hormonal, nutritional and environmental factors from fetal life throughout puberty. Although the GH-IGF axis clearly has a central role in this process, with specific actions on longitudinal growth, numerous other genes are also involved in determining stature. Indeed, genome-wide association studies have identified >600 variants associated with human height, but this still only explains a small fract...

Hyponatraemia Secondary to Exudative Eczema

Viseras Irene Pilar Fernandez , Ajzensztejn Michal

Background: Classically adrenal insufficiency presents with hyponatraemia and hyperkalaemia, however the differential may be of alternative origin. Atopic dermatitis is a common inflammatory skin disease of infancy and childhood. In severe cases, the exudation from wet lesions can produce serious complications such as infection+very rarely electrolytes abnormalities as seen in this case.Case report: A 6-month-old female infant was referred for endocrine ...
