objective: aggression is a disruptive behavior that limits children’s ability for a better adjustment. as commonly reported, sleep problems is associated with the presentation of aggression in adhd children. in this study, we aimed to investigate the association between sleep problems and aggressive behavior in children with adhd.  methods: the study method is correlational and cross-sectional....

effects of oral administration of testosterone and fluoxetine exposure on aggressive behavior of the fighting fish, betta splendens , were investigated. testosterone diluted in ethanol and sprayed on pre-weighted pellet to achieve concentrations of 0, 1, 2 and 4 mg/kg of hormone in food. two main behaviors were recorded: the time in front of mirror and duration of the gill flaring using a mirro...

Background and Objective: Clinical behavior of basal cell carcinoma (BCC) is known to be different according to histological growth pattern and basosquamous cell carcinomas (BSC) are known with their aggressive behavior and metastatic capacity. In this study, we evaluated bcl-2 and cyclin D1 expressions in BCC and BSC cases comparatively, to explore their predictive value on the aggres...

introduction: the present study investigated the interactive effect of gabab receptors and extremely low frequency electromagnetic field (elf-emf) on foot shock-induced aggression in rats. methods: fifty adult male rats were randomly assigned into 10 groups. groups 2, 4, 6, 8 and 10 were exposed to 50 hz, 500 µt elf-emf for 30 days 8h per day while the remaining groups (1, 3, 5, 7 and 9) were s...

Introduction: Aggressive behavior is a major issue in the field of mental health. Pharmacotherapy is often used for the treatment of violent individuals. A neurochemical system most consistently linked with aggression is the GABAergic system. The aim of the present investigation was to examine the effect of muscimol (GABAA agonist) 250 and 500 ng/rat and picrotoxin (GABAA antagonist) 1.5 and...

background and objective: clinical behavior of basal cell carcinoma (bcc) is known to be different according to histological growth pattern and basosquamous cell carcinomas (bsc) are known with their aggressive behavior and metastatic capacity. in this study, we evaluated bcl-2 and cyclin d1 expressions in bcc and bsc cases comparatively, to explore their predictive value on the aggressive beha...

Testosterone is assumed to be the key hormone related to resource-defence aggression. While this role has been confirmed mostly in the context of reproduction in male vertebrates, the effect of testosterone on the expression of resource-defence aggression in female vertebrates is not so well established. Furthermore, laboratory work suggests that progesterone inhibits aggressive behaviour in fe...

Predatory (towards crickets), intermale, and maternal aggression were examined in four replicate lines of mice that had been selectively bred for high wheel-running (S) and in four random-bred control lines (C). In generation 18, individual differences in both predatory and intermale aggression were significantly consistent across four trial days, but predatory and intermale aggression were unc...

Territorial animals are known to be able to differentiate between intruding individuals posing a low or high threat and adjust their aggressive response accordingly. However, plastic territorial aggression based on recognising individuals with different attributes is typically assumed to be relevant only in the context of conspecific interactions. In this study, we investigated territorial aggr...

High levels of aggressive behaviors against intruders in the nest area are displayed by female rats during the first 10 days after delivery, declining thereafter to very low levels, even though lactation continues. Cross-fostering experiments were undertaken to test the hypothesis that pup age may affect aggression in lactating rats. The behavior of females on the 8th day after delivery when ra...
