ABSTRACT
Objective@#To discuss the correlation between growth status and eating behaviors in children with attention deficit and hyperactivity disorder (ADHD), providing reference data for management and dietary behavior guidance among ADHD children.@*Methods@#A total of 703 children aged 4-13 years old were collected from the ADHD patients from Children s Health Department of Children s Hospital of Nanjing Medical University from June to September, 2019. The demographic characteristics and information regarding children’s eating behaviors were collected by self-designed questionnaire and Chinese version of the parent-completed Children’s Eating Behavior Questionnaire(CEBQ). The correlation physical growth with dietary behaviors among the ADHD children were analyzed.@*Results@#Food avoidant behaviors, including satiety responsiveness, slowness in eating and emotional undereating in ADHD children with thinness scored significantly higher than that of children with short stature, overweight and obesity(F=17.57, 29.32, 4.07, P<0.01), while food approach behaviors, including food responsiveness, enjoyment of food, desire to drink and emotional overeating scored higher in obese children, compared to other three groups(F=24.54, 47.44, 2.96,5.85, P<0.05). Multiple linear regression analysis showed that, after adjusting for the confounders, satiety responsiveness, slowness in eating were still negatively associated with BMI-Z score of the ADHD children(B=-0.05, -0.07, P<0.01). Food responsiveness, enjoyment of food and emotional overeating had a positive association with the BMI-Z score(B=0.04, 0.09, 0.05, P<0.05).@*Conclusion@#Emotional eating and high food responsiveness in ADHD children are associated with the overweight and obesity, while long eating time and high satiety responsiveness is associated with underweight among ADHD children. For clinical doctors and parents, problematic eating behaviors among ADHD children should be concerned regarding its negative effects on growth and development, besides core symptoms of ADHD.
ABSTRACT
Aim To generate the mouse FoxGl overexpression in the specific brain region based on App/psl mice. Methods A FoxGl transgenic mouse line CAG-loxp-stop-loxp-FoxG1-IRES-EGFP was introduced from Southeast University. By crossing B6; 129-5-HT1Btml(CreERT)Cre with this line, we generated a transgenic mouse line Cre; FoxGl. By crossing App/ps1 with this line, combined with tamoxifen induction, FoxG1 was ectopically expressed in the cortex, striatum and hippocampus in app/ ps1 mice. Results The offspring of the mice over expression of FoxGl in the specific brain region of App/ps1 mice were successful in generation. Conclusions FoxG1 overexpression mice in Alzheimer's Disease brain region is obtained by using reasonable gene recombination, providing new model into the mechanism underlying the Alzheimer's disease related with FoxG1.
ABSTRACT
Low temperature storage is a common method for storing pomegranates post-harvest; however, unsuitable low temperaturescan cause fruit chilling injuries, the molecular mechanism of which is as yet unclear. Ethylene is a major factor affecting thepost-harvest storage quality of pomegranates, and functions mainly through the ethylene signal transduction pathway.ERF1, ERF2 and ETR are key genes in the ethylene signal transduction pathway. Here, we used RACE and homologouscloning techniques to obtain PgERF1 (KU058889), PgERF2 (KU058890) and PgETR (KU058891) from Punica granatumcv. Yushizi. Sequence alignment and functional domain analysis revealed that both PgERF1 and PgERF2 contained aDNA-binding-site at the 120th to 177th amino acids of the N-terminus, which is a typical AP2/ERF center structuredomain. Analysis of changes in expression of PgERF1, PgERF2 and PgETR following storage for different lengths of time(0, 14, 28, 42 and 56 days) at different temperatures (0C, 5C, 10C and 15C) revealed that the expression levels ofPgERF1 and PgERF2 had a significant positive correlation. At the same time, the expression of both PgERF1 and PgERF2increased continuously with time when seeds were stored at 0C. However, there was no obvious linear relationshipbetween time stored and the levels of expression of PgETR. Therefore, we inferred that at 0C, the ethylene signaltransduction pathway might play an important role in fruit chilling injuries during post-harvest storage.
