Summary: This study examined the impact of neuroticism on nomophobia among Chinese college students and the mediating effects of attachment and loneliness. The results showed positive correlations between neuroticism, loneliness, attachment anxiety, and nomophobia. Attachment avoidance was not significantly related to neuroticism, loneliness, and nomophobia. Neuroticism directly predicted nomophobia, and attachment anxiety and loneliness sequentially played a mediating role in the relationship between neuroticism and nomophobia. Furthermore, the mediating models differed in the subdimension of nomophobia-losing Internet connection, particularly in social media, at different levels of attachment avoidance.

Summary: The study found associations between COMT haplotypes and DNA methylation, cytokine expression, and symptoms in patients with CFS/FM, but not specific to one condition. Significant differences were observed in increased DNA methylation in the MB-COMT promoter and decreased IFN-gamma expression in patients.

Summary: In this study, fear and anxiety are examined in the context of personality and psychopathology models, along with their assessment. Anxiety is a sustained, future-oriented response to potential threat, while fear is a brief, present-focused response to acute threat. Assessing individual differences in fear can be done through phobic responses to specific stimuli or through differentiating between harm avoidance and risk taking. These measures are correlated with various personality traits and factors within psychopathology models.

Summary: This article explores the relationships between fear and anxiety within structural models of personality and psychopathology, as well as important issues related to their assessment. Anxiety represents a core facet within the domain of neuroticism, while fear is a response to acute threat. Different assessment methods reflect individual differences in fear and anxiety.

Summary: The COMT gene has been considered as the pain sensitivity gene for almost two decades, but there is inconsistent evidence in the literature. Our meta-analyses of 31 samples and 4631 participants showed small effects of rs4680 on pain thresholds in fibromyalgia, headache, and chronic pain conditions. The effects of rs4680 were found in pain patients when affected body sites were assessed. No effects were found for other investigated SNPs. These results support the theory that rs4680 may only impact behavioral measures of pain under certain conditions.

Summary: The study identified Scutellariae radix as the most potent inhibitor of hCOMT among 53 herbal products. Specific chemicals like scutellarein, baicalein, and oroxylin A from the extract were found to be potent COMT inhibitors. These findings suggest the potential for developing more effective non-nitrocatechol COMT inhibitors for biomedical applications.

Summary: This study investigated the impact of the COMT gene on pain sensitivity and found that the low pain sensitivity haplotype is influenced by genetic variation in gene expression, rather than SNP rs4680. The results suggest that the frequency of the COMT low pain sensitivity haplotype varies widely among global populations.

Summary: The study revealed that the flavonoids in vine tea exhibit strong inhibition against human catechol-Omethyltransferase, with myricetin being the most potent compound. This finding not only has implications for the drug exposure of catechol drugs, but also provides a promising lead compound for developing more effective hCOMT inhibitors.

Summary: The study reported the biochemical and structural analysis of COMT enzyme from Niastella koreensis, revealing that its activity is mainly influenced by magnesium ion, but also shows significant activity with copper and zinc ions. Structural analysis showed that the region near the SAM binding site undergoes conformational changes upon binding of the cosubstrate and the metal ion. Additionally, by developing variants, the activity and selectivity of NkCOMT can be enhanced.

Summary: This systematic review examines the relationship between genetic polymorphisms and vulnerability to psychosis induced by cannabis. The findings suggest that genes involved in dopamine pathways, such as COMT and AKT1, are associated with a higher risk for cannabis-induced psychosis. Additionally, a genetic variant near the cholinergic receptor muscarinic 3 was identified as being predisposing to cannabis-induced hallucinations. The study emphasizes the need for broader genetic research to enhance our understanding of cannabis-induced psychosis and improve prevention and treatment strategies.

Summary: This study adopted a new concept of empathy to explore its relationship with age and COMT gene polymorphisms. The findings showed significant differences in empathy indicators among individuals with different genotypes in specific age groups. Additionally, age and education can shape an individual's empathy together with inherent factors.

Summary: This study conducted a meta-analysis to examine the association between the rs4680 polymorphism in the COMT gene and OUD. The results showed a significant association between rs4680 and OUD in Asians, but no association in Caucasians.

Summary: The study investigated the novel biological activities of NDGA in relation to COMT and how COMT inhibition by NDGA affects 4-OHE2-induced cyto- and genotoxicity in MCF-7 human breast cancer cells. The results showed that NDGA both inhibits COMT-mediated formation of 4-MeOE2 and increases 4-OHE2-induced DNA damage and cytotoxicity, potentially increasing catechol estrogen-induced genotoxicities in mammary tissues.

Summary: This study investigated the effects of tDCS on swallowing function in individuals with different COMT gene polymorphisms. The results showed that individuals with COMT Val/Val polymorphism experienced improvement in swallowing motor function after tDCS, while those with COMT Met carrier group did not show significant changes.

Summary: Anxiety, specifically neuroticism and worry, is associated with elevated risk of cardiometabolic disease, with higher anxiety levels leading to stable differences in cardiometabolic risk (CMR) that persist into older ages. This study suggests that individuals with higher levels of anxiety may experience earlier deteriorations in cardiometabolic health and remain at a heightened risk throughout their lives.

Summary: This study examined the associations between postdeployment neurocognitive performance and subsequent intimate partner violence (IPV) among warzone veterans. The findings showed that greater psychopathology, history of traumatic brain injury (TBI), and poorer neurocognitive performance were associated with higher perpetration of IPV in warzone veterans. These results highlight the importance of considering both psychological/behavioral and neurocognitive factors in understanding and preventing IPV among warzone veterans.
