In the dental practice, several situations that might lead to conflict are imaginable. How a dentist deals with a conflict depends in part on the importance he places on the content of the conflict in relation to the importance of the relationship with the patient. This article briefly describes 5 conflict management styles. Read More

Among Alzheimer's disease (AD) patients, it is very common to develop behavioral and psychological symptoms of dementia (BPSD), which has a close relation to the excess morbidity and mortality, greater healthcare use, earlier institutionalization, and caregiver burden. With evaluation of AD patients, the present study mainly aims to investigate whether citalopram would be efficient for BPSD, and examines citalopram's effects on cognitive function, caregiver distress, safety and tolerability. Eighty patients diagnosed with moderate AD and clinically significant BPSD from April 2015 to January 2016 were enrolled in this study. Read More

Neuropeptide F in invertebrates is a homolog of neuropeptide Y in mammals and it is a member of FMRFamide-related peptides. In arthropods, such as insects, there are two types of neuropeptide F comprising long neuropeptide F (NPF) and short neuropeptide F (sNPF). Both NPFs are known to play a crucial role in the regulations of foraging, feeding-related behaviors, circadian rhythm, stress responses, aggression and reproduction in invertebrates. Read More

Primates must balance the need to monitor other conspecifics to gain social information while not losing other resource opportunities. We consolidate evidence across the fields of primatology, psychology, and neuroscience to examine individual, population, and species differences in how primates, particularly macaques, monitor conspecifics. We particularly consider the role of serotonin in mediating social competency via social attention, aggression, and dominance behaviors. Read More

In several rodent species social play appears to be necessary for proper deployment of species-specific patterns of aggressive and reproductive behavior. Specifically, in male Syrian hamsters (Mesocricetus auratus), play has been linked to the development of adult aggression. We quantified several types of social play behavior in same-sex peer groups ofSyrian hamsters three times per week for three consecutiveweeksafter weaning, which included postnatal days 22-42 (PD22 to PD42).

Identity development depends on the ability to say 'no.' Setting limits enables a relationship between two separate individuals to develop. Early trauma can leave the individual so vigilant to others' demands that internal prohibitions against intrusion remain silenced, which we conceptualize as a 'no' that could not be sufficiently articulated to keep the person safe.

Two types of extracellular vesicles (EVs), exosomes and ectosomes, are generated and released by all cells, including immune cells. The two EVs appear different in many properties: size, mechanism and site of assembly, composition of their membranes and luminal cargoes, sites and processes of release. In functional terms, however, these differences are minor. Read More

Verbal bullying among adolescents, which has become increasingly prevalent in recent years, often involves swearing or sexually ridiculing one's family members or peers. Because many factors underlying the initiation of verbal bullying remain unknown, Giorgi's phenomenological method was used to examine the essence and meaning of verbal bullying among adolescents, which is an urgent issue in the field of nursing in South Korea.

Aggression is a crucial survival behavior: it is employed to defend territory, compete for food and mating opportunities, protect kin, and resolve disputes. Although widely differing in its behavioral expression, aggression is observed across many species. The neural substrates of aggression have been investigated for nearly a century and two highly conserved circuitries emerge as critical substrates for generating and modulating aggression. Read More

Diagnosis of prostate cancer is based on histological evaluation of tumor architecture using a system known as the 'Gleason score'. This diagnostic paradigm, while the standard of care, is time-consuming, shows intra-observer variability and provides no information about the altered metabolic pathways, which result in altered tissue architecture. Characterization of the molecular composition of prostate cancer and how it changes with respect to the Gleason score (GS) could enable a more objective and faster diagnosis. Read More

Callous-unemotional (CU) traits are thought to confer risk for aggression via reduced amygdala responsivity to distress cues in others. Low cortisol reactivity is thought to confer risk for aggression via reduced arousal and this effect may be confined to boys. We tested the hypothesis that the association between childhood CU traits and aggression would be greatest in the absence of the inhibitory effects of cortisol reactivity, and that this effect would be sex dependent.

Aggressive behavior (AB) is a multifaceted disorder based on the interaction between genetic and environmental factors whose underlying mechanisms remain elusive. The best-characterized gene by environment (GxE) interaction for AB is the relationship between child neglect/abuse and low-activity alleles of the monoamine-oxidase A (MAOA) gene. MAOA oxidizes monoamines like serotonin and dopamine, whose aberrant signaling at discrete developmental ages plays a pivotal role in the ontogeny of AB. Read More

Childhood sexual abuse (CSA) poses a risk for sexual revictimization. Additionally, according to theory CSA may lead to identification with the aggressor, expressed by adopting the perpetrator's experience concerning the abuse; identifying with the perpetrator's aggression; replacing one's agency with that of the perpetrator; and becoming hyper-sensitive to the perpetrator. Although clinical impressions suggest that identification with the aggressor underlies reenactment of trauma, this linkage between identification with the aggressor and sexual revictimization remains largely uninvestigated.

It was predicted that Latent Profile Analysis (LPA) would reveal a "low reactivity" group, characterized by symptoms of emotional numbing and callous-unemotional (CU) traits, and a "high reactivity" group, characterized by symptoms of hyperarousal and emotional dysregulation. It was hypothesized that the low reactivity group would have higher rates of violent offending and proactive aggression than the high reactivity group. Read More
