... It is probably true to say that the reason behind some Islamic instructions, regarding hijab and the observance of some issues, especially communication with distance between women and men, might be related to the connection of pheromones to the receptors, such that the pheromones of male and female hormone activate the sexual arousal when binding to their receptors in the opposite sex, not to the same sex or those who share the same mother or father. In other words, they do not activate the same familiar genetic structures (14). ...

... It has been proposed that b-cell translocation gene 2 (btg2) and ier2a are key regulators of vertebrate neural development (Moriya et al., 2016). Previous investigations associating btg2 deletion in zebrafish and mice with aberrant aggression raise the possibility that both genes are crucial for brain processes related to aggression (Malki et al., 2016;Liu et al., 2020). The vgf (VGF nerve growth factor-inducible), a neuropeptide involved in crucial neural processes such as synaptic plasticity, neurogenesis, and brain neurite growth, is produced by brain-derived neurotrophic and nerve growth factors (Mizoguchi et al., 2017;Takeuchi et al., 2018) and has been shown to have neuroprotective effects on retinal ganglion cells (Takeuchi et al., 2018). ...

... Deficiency of tryptophane hydroxylase and 5-day predation stress Tph2 +/− male mice Increased aggressive behaviours in males; reduced brain serotonin content, reduced expression of 5-HT6 receptor, GSK3-β overexpression [72] Tph2 +/− female mice Increased aggressive behaviours in females; reduced brain serotonin content, GSK3-β and myelin basic protein overexpression; deficient neuroplasticity, downregulation of synaptophysin [73] Another stress paradigm that is used to elicit aggression in experimental rodents is chronic mild stress [18,74]. Chronic unpredictable stress was found to provoke increased aggression in male BALB/C, CD1 and C57BL/6J mice, as shown in the resident-intruder test [51][52][53][54][55]. C57BL/6J mice exposed to a chronic mild stress paradigm showed increased offensive and aggressive behaviours in the resident-intruder test and the social dominance tube test [75]. ...

... A gyermekeket ért szexuális bűncselekmények motivációs és oksági háttere régóta a kutatások érdeklődésének fókuszában áll, mert a feltárt tényezők mind a kockázatbecslés, mind a prevenciós és intervenciós gyakorlat szempontjából kulcsfontosságúak (BAUR et al., 2016). ...

... A human genetic study that was focused on female patients with severe alcohol dependence in Sweden reported that two haploid genotypes of the GHSR gene were associated with smoking status [130]. Another study showed that the minor allele of the rs2948694 singlenucleotide polymorphism (SNP) was located in the GHSR-1A gene (GHSR), but none of the tested SNPs of the pre-proghrelin gene (GHRL) appeared to be associated with an increased severity of cigarette smoking [131]. ...

... Due to the inclusion of twins in the sample, responses regarding the frequency of childhood maltreatment and sexual orientation were compared to various Finnish population samples. (e.g., Albrecht et al., 2014) of the overall population. Our sample outcomes are pertinent to non-identical twins, as we noticed no statistically significant differences between our samples. ...

... Inflammation and immune functions were the most important pathways unveiled by the sPLS or sPLSDA analyses. Other transcriptomic studies conducted in mouse models of aggressiveness [60] or in zebrafish [61] but on brain tissues, led to the same conclusions. In mice prefrontal cortex of aggressive versus non-aggressive mice, the transcriptomic analysis uncovered NFKB and MAPK pathways which are known to be both involved in inflammation [60]. ...

... For example, in a representative Québec sample, child sexual abuse was associated with psychological, physical, and sexual violence among both males and females (Hébert et al., 2017). Finally, child maltreatment has been associated with experiencing sexual coercion or exploitation later in life (Forsman et al., 2015;Layne et al., 2014). ...

... As a popular measure of Big Five personalities, the BFI-44 includes 44 items that are rated on a 5-point Likert scale ranging from 1 (disagree strongly) to 5 (agree strongly). Prior studies have shown adequate validity and reliability of the BFI-44 in different Chinese samples [44][45][46]. The Cronbach's αs for BFI-44 subscales in this study were acceptable: extraversion (0.72), agreeableness (0.72), conscientiousness (0.80), neuroticism (0.78), and openness (0.78). ...

... [12]- [14]); but it is not clear if they emerge for the first time at that age or if they are revealed because they become more pronounced. These differences continue in the adult stage: it has been reported that whereas women tend to be higher in anxiety, men tend to be higher in avoidance [15], although the magnitude of the dissimilarity varies from small to moderate depending on the cultural region considered [16]. Other investigation [17] found significant effects in romantic attachment when anxiety and avoidance dimensions were divided into facets: avoidance into self-reliance and discomfort with closeness, and anxiety into neediness, preoccupation, and a rejected desire for closeness. ...
