[Efficacy of combination of needle extract, hesperidin and vitamin C in treatment of chronic venous diseases].

Angiol Sosud Khir 2021 ;27(2):82-91

Laboratory of Physiology of Visceral Systems named after K.M. Bykov, Institute of Experimental Medicine, Saint Petersburg, Russia.

Background: In Russia, physicians are virtually unaware of drugs based on needle extract. However, abroad, saponins and, in particular, a combined preparation containing needle extract, hesperidin and vitamin C is one of drugs of choice, if not the leading medication in treatment of venous oedemas and other venous symptoms.

Aim: The authors conducted a systematic review of the Russian-and English-language literature using the following search terms: saponins, hesperidin, needle, ruscus, ruscogenin (and their Russian equivalents), each of which was entered in a combination with the word 'venous' or its Russian equivalent, respectively.

Promoting parenting in home visiting: A CACE analysis of Family Foundations.

J Fam Psychol 2021 Jun 24. Epub 2021 Jun 24.

Edna Bennett Pierce Prevention Research Center, The Pennsylvania State University.

This randomized trial tested the impact of an established prevention program for first-time parents, Family Foundations, adapted for low-income mothers and fathers as a series of sessions provided to couples in their homes. To assess program impact, we recruited and randomly assigned a sample of 150 low-income adult mother-father dyads (not necessarily still romantically involved, cohabiting, or married) during pregnancy or shortly after birth. The randomly assigned intervention families participated in Family Foundations Home Visiting (FFHV), consisting of 11 in-home sessions focusing on parental cooperation, collaboration, and conflict management to support children's development.

Examining the joint development of antisocial behavior and personality: Predictors and trajectories of adolescent indirect aggression and machiavellianism.

Dev Psychol 2021 May;57(5):805-813

Counselling Psychology, Faculty of Education, University of Ottawa.

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were investigated. Predictors of joint trajectory groups at the start of high school (Grade 9) were also explored. Read More

Evidence for association of vasopressin receptor 1A promoter region repeat with childhood onset aggression.

J Psychiatr Res 2021 May 27;140:522-528. Epub 2021 May 27.

Centre for Addiction and Mental Health, Toronto, Ontario, Canada; Institute of Medical Science & Department of Psychiatry, University of Toronto, Toronto, Ontario, Canada.

Objective: Childhood onset aggression can cause major suffering to affected families and is associated with many negative outcomes in the child's later life, including poor academic performance, adolescent delinquency, drug abuse, depression and antisocial personality disorder. Currently available prevention and intervention strategies have limited efficacy, but a better understanding of underlying genetic and neurobiological factors can lead to more effective prevention and treatment strategies, through genetic screening programs and novel therapies.

Method: This study examined the RS1 (n = 299 aggression, n = 192 controls) and RS3 (n = 291 aggression, n = 189 controls) microsatellite repeats within the promoter region of the vasopressin receptor 1A gene (AVPR1A) and their association with extreme childhood aggression, as assessed by the Child Behavior Checklist (CBCL), as well as the Teacher Report Form (TRF) and Youth Self Report (YSR).

Dominance rank, female choice, and reproductive success in semi-free ranging adult male Japanese macaques (Macaca fuscata).

Am J Primatol 2021 Jun 22:e23294. Epub 2021 Jun 22.

Department of Anthropology, University of Oregon, Eugene, Oregon, USA.

The assumed evolutionary advantage of dominance is increased reproductive success. However, the efficacy of dominance as a mating strategy may be interrupted by any number of variables including female choice, estrous synchrony, and mating by non-troop males. In Japanese macaques (Macaca fuscata), there is evidence both for and against dominance as conferring reproductive success for adult males, with many discussions pointing to the importance of female choice in governing reproductive success in certain populations.

The Impact of Childhood Bullying Trajectories on Young Adulthood Antisocial Trajectories.

J Youth Adolesc 2021 Jun 22. Epub 2021 Jun 22.

Counselling Psychology, Faculty of Education, University of Ottawa, Ottawa, ON, K1N 6N5, Canada.

Long-term outcomes of childhood bullying perpetration have been explored, but heterogeneity in outcomes reflecting nonclinical antisocial tendencies including indirect aggression, psychopathic personality, and interpersonal relations have not been examined from a person-centered approach. Accordingly, latent class growth analyses were used to examine trajectory groups of childhood bullying perpetration across ages 10 to 18 and multi-trajectory groups of young adulthood outcomes across ages 19 to 23 (indirect aggression, psychopathic personality, interpersonal relations). In a sample of 701 participants (52. Read More

Female Narcissism: Assessment, Aetiology, and Behavioural Manifestations.

Psychol Rep 2021 Jun 22:332941211027322. Epub 2021 Jun 22.

Nottingham Trent University, Centre for Academic Development and Quality, Nottingham, UK.

Despite putative gender differences in the expression of narcissism, prominent theories have virtually dismissed the role of females in the development and manifestation of narcissism. The contention that narcissism is a pathology of the self that may partly differ in males and females is further evident in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The DSM-5 reports that up to 75% of those diagnosed with Narcissistic Personality Disorder (NPD) are men. Read More

Nuclear androgen and progestin receptors inversely affect aggression and social dominance in male zebrafish (Danio rerio).

Horm Behav 2021 Jun 18;134:105012. Epub 2021 Jun 18.

Department of Biology, East Carolina University, Greenville, NC 27285, USA. Electronic address:

Aggression is a fundamental behavior displayed universally among animal species, but hyper- or hypo-aggressiveness can be maladaptive with negative consequences for individuals and group members. While the social and ecological significance of aggression is well understood, the specific neurobiological and hormonal mechanisms responsible for mediating aggression have not been fully elucidated. Previous studies have shown a relationship between aggressive acts and circulating gonadal steroids, but whether classical nuclear steroid receptors regulate aggression in animals is still uncertain.

Toddlers' expectations of corporal third-party punishments against the non-defender puppet.

J Exp Child Psychol 2021 Jun 16;210:105199. Epub 2021 Jun 16.

Department of Psychology and Cognitive Science, University of Trento, 36068, Rovereto, Italy. Electronic address:

Recent research has demonstrated that toddlers expect individuals to approach and reward those who defend a victim from an aggressor rather than those who refuse to do so. This work focused on toddlers' expectations of corporal third-party punishments trought various actions, such as hitting with a stick or repelling someone who refused to defend a social partner following aggression. Using a violation of expectation paradigm (VoE), three experiments were carried out to investigate whether 21-month-olds expect others to apply different kinds of corporal punishments against the non-defender puppet (expected event) rather than the defender puppet (unexpected event), showing a bystander hitting with a stick (Experiment 1) or pushing strongly (Experiment 3) each of the two puppets.
