Background: Various factors affect child behavior in different situations such as in a dental clinic. The purpose of this study was to investigate the relationship between temperament and child behavior during routine dental treatment.
Materials And Methods: The present study is a descriptive-analytic study that included 199 children aged 3-7-years from patients referred to a dental clinic of Guilan University of Medical Sciences in 2017-2018. The Children's Behavior Questionnaire, which is specific to children aged 3-7 years, was used to assess children's dental temperament. Children's behaviors during dental treatment were recorded using Frankl scale. Finally, the data were analyzed by the SPSS-16 statistical software.
Results: About 47.9% of the samples were female, with a mean temperament score of 4.79 which was significantly higher than males ( < 0.05). Almost 2.4% of children had completely negative behaviors and 2.8% had a completely positive behavior. The mean scores of fear ( = 0.008) and anger ( = 0.004) in children with completely negative behavior were higher than those with completely positive behavior. Moreover, the average scores of inhibitory control ( = 0.003) and perceptual sensitivity ( = 0.001) in completely positive children were higher than completely negative children.
Conclusion: The results of the present study showed that girls had a better mean score of temperament than boys. The inhibitory control and perceptual sensitivity in completely positive children were significantly higher than negative children. In addition, a higher mean score of fear and anger was observed in completely negative children.

Background: The authors aimed to explore the association of fatty acids with periodontitis and its severity and to assess causality using Mendelian randomization (MR) analyses.
Methods: Data for participants with complete data were extracted from the 2009-2014 National Health and Nutrition Examination Survey. Weighted logistic regression was used to explore the relationship between dietary fatty acids and periodontitis and its severity.

Soil seed bank (SSB) is valuable reserves of seeds hidden in the soil and are especially important for the preservation and establishment of vegetation under adverse environmental conditions. However, there is a lack of knowledge on the effects of restoration measures on SSB, especially in arid ecosystems. Here, we assess the impacts of oil mulching (1 and 3 years after mulching) and plantations (15-year-old) on the diversity and composition of SSB and aboveground vegetation (AGV) in comparison with those in non-restored areas (i.

Background: Worldwide, lung cancer (LC) is the second most frequent cancer and the leading cause of cancer related mortality. Low-dose CT (LDCT) screening reduced LC mortality by 20-24% in randomised trials of high-risk populations. A significant proportion of those screened have nodules detected that are found to be benign.

Background: The effect of statins use on the incidence of Alzheimer's disease (AD) is still under debate, and it could be modified by a series of factors.
Objectives: We aimed to examine the association of statins use with the risk of cognitive impairment and AD, and assess the moderating roles of genetic susceptibility and other individual-related factors.
Design: A longitudinal study was conducted from the UK Biobank where individuals completed baseline surveys (2006-2010) and were followed (mean follow-up period: 9 years).

Background: The potential pairwise connections among high-sensitivity C-reactive protein (hs-CRP), striatum-based circuits, and anhedonia in adolescent depression are not clear. This study aimed to explore whether hs-CRP levels in adolescents with depression influence anhedonia via alterations of striatum-based functional connectivity (FC).
Methods: A total of 201 adolescents (92 with depressive episodes with anhedonia (anDE), 58 with DE without anhedonia (non-anDE), and 51 healthy controls (HCs)) underwent resting-state functional magnetic resonance imaging (fMRI) and completed the anhedonia subscale of the Children's Depression Inventory (CDI).
