Cinnamaldehyde protects against ligature-induced periodontitis through the inhibition of microbial accumulation and inflammatory responses of host immune cells.

Cinnamaldehyde (CA), the main active ingredient in cinnamon, has been proved to be a potential candidate for controlling inflammation; however, there has been little evidence demonstrating its role in alleviating periodontitis. The aim of this study was to investigate the effect of orally administered CA on ligature-induced periodontitis in mice and the administration of CA on the (Pg) supernatant-induced inflammatory responses of murine macrophages and human periodontal ligament cells (HPDLCs). experiments showed that the oral administration of CA significantly inhibited bone resorption, the accumulation of anaerobic bacteria and host immuno-inflammatory responses in ligature-induced periodontitis in mice.

Teacher's Emotional Intelligence and Employee Brand-Based Equity: Mediating Role of Teaching Performance and Teacher's Self-Efficacy.

Educational institutions need to respond to global competitive problems, and branding has become a method for higher education institutions to differentiate themselves. Thus, this study attempted to investigate predictors of employee brand-based equity. A cross-sectional research design has been used to record the perception of the teachers, and data are collected using a convenience sampling technique.

Toward the Impact of EFL Teachers' Self-Efficacy and Collective Efficacy on Students' Engagement.

Given the centrality of students' engagement in their academic success, considerable attention has been paid to this construct and its potential predictors. Notwithstanding, a limited number of studies have focused on the role of teacher self- and collective efficacy as antecedents of student engagement. Further, no review study has been carried out to illustrate the impact of EFL teacher' efficacy on learning engagement.

Sex differences of oxytocin and vasopressin in social behaviors.

The neuropeptides oxytocin (OT) and vasopressin (VP) are known to mediate social cognition and behaviors in a sex-dependent manner. This chapter reviews the sex-dependent influence of OT and VP on social behaviors, focusing on (1) partner preference and sexual orientation, (2) memory modulation, (3) emotion regulation, and (4) trust-related behaviors. Most studies suggest that OT promotes familiar (opposite-sex) partner preference, strengthens memory, relieves anxiety, and increases trust.

[Effect of electroacupuncture at "Weizhong" (BL40) on expression of muscular PDGF-CC, PDGFR-α and MMP-1 in rats with lumbar multifidus muscle injury].

Objective: To observe the effect of electroacupuncture (EA) of "Weizhong" (BL40) on the expression of platelet-derived growth factor (PDGF)-CC, PDGF receptor (PDGFR)α and matrix metalloproteinase-1 (MMP-1) in rats with lumbar multifidus muscle injury (LMMI) so as to study its mechanisms underlying improvement of skeletal muscle injury.

Methods: Fifty-four male SD rats were randomly divided into normal group (=6), model group (=24) and EA group (=24), and the latter two groups were further divided into four subgroups (1, 3, 5 and 7 days), with 6 rats in each group. The LMMI model was established by injection of 0.

Nitrogen-containing flavonoid and their analogs with diverse B-ring in acetylcholinesterase and butyrylcholinesterase inhibition.

In this study, a series of new flavones (2-phenyl-chromone), 2-naphthyl chromone, 2-anthryl-chromone, or 2-biphenyl-chromone derivatives containing 6 or 7-substituted tertiary amine side chain were designed, synthesized, and evaluated in acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibition. The results indicated that the alteration of aromatic ring connecting to chromone scaffold brings about a significant impact on biological activity. Compared with flavones, the inhibitory activity of 2-naphthyl chromone, 2-anthryl-chromone derivatives against AChE significantly decreased, while that of 2-biphenyl chromone derivatives with 7-substituted tertiary amine side chain is better than relative flavones derivatives.

Interactive effects of gender and sexual orientation on cortical thickness, surface area and gray matter volume: a structural brain MRI study.

Background: Testosterone is thought to play a crucial role in sexual differentiation of the brain, and sexual orientation is programmed into our brain structures even when we are still fetuses. Although gender and sexual orientation differences have been shown respectively in many brain structures, the mechanism underlying the sexual differentiation of the brain is still unknown. The study is to investigate the interactive effects of gender and sexual orientation on cerebral structures in homosexual and heterosexual people.

Gut Microbiota in Bipolar Depression and Its Relationship to Brain Function: An Advanced Exploration.

The mechanism of bipolar disorder is unclear. Growing evidence indicates that gut microbiota plays a pivotal role in mental disorders. This study aimed to find out changes in the gut microbiota in bipolar depression (BD) subjects following treatment with quetiapine and evaluate their correlations with the brain and immune function.

Gut Microbiota Changes in Patients with Bipolar Depression.

This study aims to characterize the gut microbiota in depressed patients with bipolar disorder (BD) compared with healthy controls (HCs), to examine the effects of quetiapine treatment on the microbiota, and to explore the potential of microbiota as a biomarker for BD diagnosis and treatment outcome. Analysis of 16S-ribosomal RNA gene sequences reveals that gut microbial composition and diversity are significantly different between BD patients and HCs. Phylum and are the predominant bacterial communities in BD patients and HCs, respectively.

Sexual dimorphism of oxytocin and vasopressin in social cognition and behavior.

The neuropeptides oxytocin (OT) and vasopressin (VP) are hormones that are known to mediate social behavior and cognition, but their influence may be sex-dependent. This paper aims to provide a comprehensive review of the sex-related influence of OT and VP on social cognition, focusing on partner preference and sexual orientation, trust and relevant behaviors, memory modulation, and emotion regulation. Most studies have suggested that OT facilitates familiar-partner preference in both sexes, with females being more significant, increased trust in others, especially for male, enhanced memory in either sex, and reduced anxious emotion in males.
