C Sue Carter
Selective relationships and attachments are central to human health and well-being, both in current societies and during the course of evolution. The presence or absence of social bonds has consequences across the lifespan. The neurobiology of attachment is grounded in neuroendocrine substrates that are shared with reproduction and survival. Experimental studies of species, such as sheep or prairie voles, capable of showing selective social behaviors toward offspring or partners, have provided empirical evidence for the role of oxytocin and vasopressin in the formation of selective attachments...

The current study examined to what extent early adolescents' implicit and explicit evaluations of a classmate predict (a) their own aggressive behavior toward that classmate and (b) their classmate's aggressive behavior toward them. Implicit and explicit peer evaluations were assessed among 148 early adolescents (78 boys and 70 girls; Mage = 11.1 years) with an approach-avoidance task and a likeability rating. Adolescents' aggression was measured by the number of grams of hot sauce administered to the peer in a "taste test...

Background: Right ventricular (RV) function is an important entity in heart failure. Patients with RV dysfunction (RVD) have poorer prognosis and exercise tolerance than those with preserved RV systolic function. Tricuspid annular plane systolic excursion (TAPSE) has been proposed as a simple and reproducible parameter for the qualitative assessment of RV systolic function/ejection fraction (EF). This study aims at describing RV function/RVD among heart failure patients in a specialized cardiac facility in Southwestern Nigeria...

The study of warfare from an evolutionary perspective has expanded rapidly over the last couple of decades. However, it has tended to focus on the ancestral origins, prevalence, and instruments of war rather than adaptationist analyses of its underlying psychology. I argue that our evolved coalitional psychology may contain a set of distinct evolved heuristics designed specifically for offensive and defensive coalitional aggression. Data from two survey experiments are presented, in which subjects were given scenarios depicting offensive or defensive aggression and were told to make decisions, for example, regarding their willingness to participate in the conflict, their opinions of others who did not choose to participate, and their expectations benefit...

REVIEW
Qizheng Cai, Lei Feng, Kai Zhen Yap
Recent studies suggested oxytocin as a possible drug to treat social deficits caused by Autism Spectrum Disorder (ASD), but the safety of intranasal oxytocin in autistic patients is not established. The aim of this review was to characterise the side effect profile of long-term intranasal oxytocin in treatment of ASD compared to placebo. All randomised controlled trials of intranasal oxytocin in the treatment of ASD published before 1 January 2017 that reported safety data were identified from databases including Pubmed, Embase, Cochrane Library, and International Pharmaceutical Abstract...

OBJECTIVE: Past research suggests a positive link between family meals and child and adolescent health. Although researchers have often relied on how often families eat together, this may not capture the complexity of the experience. Using a birth cohort, this study examines the prospective associations between the environmental quality of the family meal experience at age 6 years and child well-being at age 10. METHODS: Participants are 1492 children of the Quebec Longitudinal Study of Child Development...

Colorectal cancer (CRC) holds the woeful record of being the most preventable but least prevented type of cancer. Although healthy lifestyles and screening programs associated to early polyp removal greatly reduce CRC incidence and CRC-related death, the overall lack of information and of effective preventive policies is promoting an overwhelming global escalation of this disease. Moreover, new challenges such as the increasing occurrence of aggressive CRC in young adults highlight underlying changes not only in the incidence but also in the nature of this disease...

Biomedical facilities across the nation and worldwide aim to develop cost-effective methods for the reproductive management of macaque breeding groups, typically by housing macaques in large, multi-male multi-female social groups that provide monkey subjects for research as well as appropriate socialization for their psychological well-being. One of the most difficult problems in managing socially housed macaques is their propensity for deleterious aggression. From a management perspective, deleterious aggression (as opposed to less intense aggression that serves to regulate social relationships) is undoubtedly the most problematic behavior observed in group-housed macaques, which can readily escalate to the degree that it causes social instability, increases serious physical trauma leading to group dissolution, and reduces psychological well-being...

In substance use and psychotic disorders, socially problematic behaviours, such as high aggression may, in part, be explained by deficits in social cognition skills, like the detection of emotions or intentions in others. The aim of this study was to assess the magnitude of social cognition impairment and its association with aggression in individuals with methamphetamine (MA) dependence, methamphetamine-associated psychosis (MAP), and healthy controls (CTRL). A total of 20 MAP participants, 21 MA-dependent participants without psychosis, and 21 CTRL participants performed a facial morphing emotion recognition task (ERT) across four basic emotions (anger, fear, happiness and sadness) and the reading the mind in the eyes task (RMET), and completed the aggression questionnaire...

INTRODUCTION: Little is known about the nature and extent of substance use among pregnant women in Cape Town (South Africa) despite the very high levels of substance use and related consequences such as FASD in this part of the country. The aim of the study was to determine predictors of alcohol use among pregnant women. METHODS: A cross-sectional survey was conducted among pregnant women attending 11 Midwife Obstetric Units (MOUs) in greater Cape Town. A two-stage cluster survey design was used...

Honest signaling is generally taken to be a necessary pre-condition for a stable signaling system, because deceptive signaling at a high enough rate should cause receivers to ignore the signal, which in turn undermines the utility of sending signals. Deception is normally thought to occur because of benefits it has to the deceiver. This raises the question of why signaling systems should exist and persist over time, especially in cases in which the interests of the senders and receivers are not well aligned...

In the present study, the predictors and outcomes associated with the trajectories of peer rejection were examined in a longitudinal sample of Italian children (338 boys, 269 girls) ages 10 to 14 years. Follow-up assessments included 60% of the original sample at age 16-17. Low, medium, and high rejection trajectory groups were identified using growth mixture models. Consistent with previous studies, we found that (a) being less prosocial and more physically aggressive at age 10 was characteristic of those children with the high rejection trajectory; (b) being less attractive was related to higher peer rejection from age 10 to 14; and (c) boys with a high rejection trajectory showed high levels of delinquency and anxiety-depression and low levels of academic aspiration at age 16-17, whereas girls with a high rejection trajectory showed low levels of academic aspiration and social competence at age 16-17...

BACKGROUND: Celebrities have long influenced the medical decisions of the general population. By analyzing Google search data using Google Trends, we measured the impact of highly publicized plastic surgery-related events on the interest level of the general population in specific search terms. Additionally, we investigated seasonal and geographic trends around interest in rhinoplasties, which is information that physicians and small surgical centers can use to optimize marketing decisions...

INTRODUCTION: Intimate partner violence (IPV) is a serious public health problem that frequently results in oral-maxillofacial traumas, generating high social and economic costs. The aim of this study was to describe the profile of women victims of IPV and determine the pattern of oral-maxillofacial traumas, according to a medical-legal and forensic perspective. An exploratory study of 1361 suspected cases of women victims of IPV was carried out based on database of an Institute of Legal Medicine and Forensic Dentistry of Northeastern Brazil during a period of 4 years...

Struggles managing conflict and hostility in adolescent social relationships were examined as long-term predictors of immune-mediated inflammation in adulthood that has been linked to long-term health outcomes. Circulating levels of interleukin-6 (IL-6), a marker of immune system dysfunction when chronically elevated, were assessed at age 28 in a community sample of 127 individuals followed via multiple methods and reporters from ages 13 to 28. Adult serum IL-6 levels were predicted across periods as long as 15 years by adolescents' inability to defuse peer aggression and poor peer-rated conflict resolution skills, and by independently observed romantic partner hostility in late adolescence...

We investigated how forage material affects indicators of welfare in three male Western lowland gorillas (Gorilla gorilla gorilla) at the Detroit Zoo. In addition to their maintenance diet and enrichment foods, the gorillas generally received forage material four times a week. From this baseline, we systematically manipulated how much forage material the group received on a weekly basis, with either daily or bi (twice)-weekly presentation of browse (mulberry, Morus sp.) or alfalfa hay. We collected behavioral data (60 hr per gorilla) and measured fecal glucocorticoid metabolites (FGM)...

INTRODUCTION: Odontogenic cysts are commonly encountered lesions among head and neck pathologies. Odontogenic keratocyst (OKC) has unique features of recurrence and local aggressiveness. Podoplanin (PDP) is a lymphatic endothelial marker and is shown to be expressed in a variety of tissues. Hence, we planned to assess the significance of PDP in OKC and dentigerous cyst (DC). MATERIALS AND METHODS: The present study included assessment of immunoexpression of PDP in OKC and DC...

REVIEW
Bárður Eyjólfsson Ellendersen, Anne C von Philipsborn
Drosophila melanogaster sexual behaviour relies on well-studied genetically determined neuronal circuits. At the same time, it can be flexible and is modulated by multiple external and internal factors. This review focuses on how physiological state, behavioural context and social experience impact sexual circuits in the two sexes. We discuss how females tune receptivity and other behaviours depending on mating status and how males adjust courtship intensity based on sexual satiety, age and the conflicting drive for aggression...

Chronic maternal stress during pregnancy can have long-term, detrimental consequences for the offspring. An understanding of the mechanisms responsible for mediating these effects is essential for devising therapeutic interventions. Here, we examined whether serotonin 1A receptor (5-HT1AR) mediates the effects of maternal stress on the behavioural outcomes of the offspring as adults. Heterozygous (HET) mouse dams were bred with HET males and were randomly assigned to stress or control groups. Pregnant dams in the stress group were exposed to a regime of chronic unpredictable stress from embryonic day 7 to 18...
