Three studies examined how members of a national group react to in-group wrongdoings. We expected that perceived in-group moral superiority would lead to unwillingness to repair the aggression. We also expected that internal-focused emotions such as group-based guilt and group-based shame would predict specific, misdeed-related reparative intentions but not general approach motivation toward the victim groups. In Study 1, facing the in-group's recent aggression, participants who believed that the Hungarians have been more moral throughout their history than members of other nations, used more exonerating cognitions, experienced less in-group critical emotions and showed less willingness to provide reparations for the members of the victim group...

Self-regulation processes and violent contexts play an important role in predicting adolescents' aggressive behavior; less clear is how all three constructs are linked to each other over time. The present study examined the longitudinal relations among adolescents' self-reported effortful control (EC), exposure to community violence, both as a witness and as a victim, and aggressive behavior. Participants were 768 Italian adolescents (358 males) living in a high-risk context, with a mean age at T1 of 11 years in the younger cohort and 14 years in the older cohort...

While most research on the development of antisocial and criminal behavior has considered nonviolent and violent crime together, some evidence points to differential risk factors for these separate types of crime. The present study explored differential risk for nonviolent and violent crime by investigating the longitudinal associations between three key child risk factors (aggression, emotion dysregulation, and social isolation) and two key adolescent risk factors (parent detachment and deviant peer affiliation) predicting violent and nonviolent crime outcomes in early adulthood...

Malignant hypertension can occasionally be associated with microangiopathic haemolytic anaemia. A 38-year-old male presented with nausea, vomiting, loss of appetite and oliguria for 2 weeks. He was diagnosed with hypertensive emergency with cardiac and renal dysfunction. Interestingly, further workup was diagnostic for the presence of thrombotic microangiopathy (TMA): haemoglobin =12.7 g/dL, indirect bilirubin =2.0 mg/dL, haptoglobin ≤6 mg/dL, platelet count =121 000/μL and schistocytes on peripheral smear...

M S Fanjul, R R Zenuto
Ctenomys talarum is a solitary and highly territorial species in which dominant males aggressively deter other males and monopolize reproductive activity. Female preference for dominant males is not easy to assess due to coercive mating by males. Hence, we aimed to answer if behavioural dominance and several condition-related traits like testosterone and cortisol levels, endoparasite load, and hematocrit volume may affect female preference when they have the opportunity to exert it. We designed a laboratory experiment using wild-caught C...

Glioblastoma is among the most aggressive brain tumors and has an exceedingly poor prognosis. Recently, the importance of the tumor microenvironment in glioblastoma cell growth and progression has been emphasized. Toll-like receptor 4 (TLR4) recognizes bacterial lipopolysaccharide (LPS) and endogenous ligands originating from dying cells or the extracellular matrix involved in host defense and in inflammation. G-protein coupled receptors (GPCRs) have gained interest in anti-tumor drug discovery due to the role that they directly or indirectly play by transactivating other receptors, causing cell migration and proliferation...

REVIEW
Farid G Khalafalla, Mohammad W Khan
Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and one of the most lethal human cancers. Inflammation is a critical component in PDAC initiation and progression. Inflammation also contributes to the aggressiveness of PDAC indirectly via induction of epithelial-mesenchymal transition (EMT), altogether leading to enhanced resistance to chemotherapy and poor survival rates. This review gives an overview of the key pro-inflammatory signaling pathways involved in PDAC pathogenesis and discusses the role of inflammation in induction of EMT and development of chemoresistance in patients with PDAC...

BACKGROUND: Families have an important role supporting a family member with problematic substance use (PSU), although this can often be challenging and confronting. Previous research has identified high rates of family aggression and violence within the context of PSU, although few studies have examined this issue from the perspective of affected family members (AFMs) supporting a member with PSU. The aims of the current study were to understand AFMs' experience of aggression and violence while supporting a member with PSU, and to explicate the strategies they used to prevent and cope with this behaviour...

From the discovery of the Zika virus (ZIKV) in 1947 in Uganda (Africa), until its arrival in South America, it was not known that it would affect human reproductive life so severely. Today, damage to the central nervous system is known to be multiple, and microcephaly is considered the tip of the iceberg. Microcephaly actually represents the epilogue of this infection's devastating process on the central nervous system of embryos and fetuses. As a result of central nervous system aggression by the ZIKV, this infection brings the possibility of arthrogryposis, dysphagia, deafness and visual impairment...

High neuroticism and low agreeableness have been found to predict higher levels of aggression through an increase of negative emotions such as anger. However, previous research has only investigated these indirect associations for physical aggression, whereas evidence for such indirect effects on other types of aggression (i.e., verbal or indirect aggression) is currently lacking. Moreover, no previous work has investigated the moderating role of Ability Emotional Intelligence (AEI), which may buffer against the effects of anger on aggression...

There are 18 lysine deacetylases, also known as histone deacetylases (HDACs), that remove acetyl groups from histone and non-histone proteins, thereby playing critical roles in numerous biological processes. In many human cancers, HDACs are dysregulated through mutation, altered expression, or inappropriate recruitment to certain loci. However, knowledge of the genomic and transcriptomic alterations and the clinical significance of most HDACs in breast cancer remain incomplete. We used TCGA and METABRIC datasets to perform comprehensive, integrated genomic and transcriptomic analyses of 18 HDAC genes in approximately 3000 primary breast cancers and identified associations among recurrent copy number alteration, gene expression, clinicopathological features, and patient survival...

The current study used data from two longitudinal samples to test whether self-regulation, depressive symptoms, and aggression/antisociality were mediators in the relation between a polygenic score indexing serotonin (5-HT) functioning and alcohol use in adolescence. The results from an independent genome-wide association study of 5-hydroxyindoleacetic acid in the cerebrospinal fluid were used to create 5-HT polygenic risk scores. Adolescents and/or parents reported on adolescents' self-regulation (Time 1), depressive symptoms (Time 2), aggression/antisociality (Time 2), and alcohol use (Time 3)...

The current study examined relational aggression as a potential mechanism that explains the association between off-time pubertal development and internalizing problems in youth. Youth gender was also examined as a moderator for the association between these variables. It was hypothesized that early pubertal maturation would be associated with higher levels of relationally aggressive behavior which, in turn, would be associated with elevated levels of internalizing problems. Parents of 372 children between the ages of 8 and 17 were recruited through Amazon's Mechanical Turk...

Intimate partner violence (IPV) is associated with numerous long-term consequences and warrants significant clinical attention. Recent theoretical models and empirical research have suggested that several factors play a role in the development of IPV perpetration, including childhood maltreatment, early maladaptive schemas, anger, and difficulties in emotion regulation. This study investigated the relationship between childhood maltreatment and IPV, specifically examining the mediation of this relationship by several variables thought to be related to this pernicious problem, including early maladaptive schemas, the experience of anger, and emotion regulation difficulties...

Peer victimization is predictive of serious problems in adjustment, especially among children who are both victimized and aggressive. This study investigated how different types of aggression contribute to later victimization. Specifically, we examined prospective relationships between the types of aggression that children perpetrated and the types that they experienced at the hands of others. Trained observers coded schoolyard behavior of 553 children in grades 3-6 during the initial year of a bullying intervention program...

Recently, aggressive advertisement claimed a "magic role" for plant stem cells in human skin rejuvenation. This review aims to shed light on the scientific background suggesting feasibility of using plant cells as a basis of anti-age cosmetics. When meristem cell cultures obtained from medicinal plants are exposed to appropriate elicitors/stressors (ultraviolet, ultrasound ultraviolet (UV), ultrasonic waves, microbial/insect metabolites, heavy metals, organic toxins, nutrient deprivation, etc.), a protective/adaptive response initiates the biosynthesis of secondary metabolites...

Recent literature suggests that posttraumatic stress disorder (PTSD) symptoms can interact with personality factors to predict externalizing behaviors. Engagement in externalizing behaviors such as substance abuse and aggressive behavior may, in turn, increase risk for further trauma exposure and a more chronic course of PTSD. In order to better understand how to intervene on this cycle, the current study aimed to identify factors that could explain risk for externalizing behaviors among trauma-exposed veterans...

Papillary Thyroid Cancer (PTC) is an endocrine malignancy in which BRAF(V600E) oncogenic mutation induces the most aggressive phenotype. In this way, considering that lncRNAs are arising as key players in oncogenesis, it is of high interest the identification of BRAF(V600E)-associated long noncoding RNAs, which can provide possible candidates for secondary mechanisms of BRAF-induced malignancy in PTC. In this study, we identified differentially expressed lncRNAs correlated with BRAF(V600E) in PTC and, also, extended the cohort of paired normal and PTC samples to more accurately identify differentially expressed lncRNAs between these conditions...

Pancreatic ductal adenocarcinoma (PDAC) is marked by an abundant stromal deposition. This stroma is suspected to harbor both tumor-promoting as well as -suppressing properties. This is underscored by the disappointing results of stroma targeting in clinical studies. Given the complexity of tumor-stroma interaction in PDAC, there is a need to identify the stromal proteins that are predominantly tumor-promoting. One possible candidate is SPOCK1 that we previously identified in a screening effort in PDAC. We extensively mined PDAC gene expression datasets, and used species-specific transcript analysis in mixed-species models for PDAC to study the patterns and driver mechanisms of SPOCK1 expression in PDAC...

In response to the same moral violation, some people report experiencing anger, and others report feeling disgust. Do differences in emotional responses to moral violations reflect idiosyncratic differences in the communication of outrage, or do they reflect differences in motivational states? Whereas equivalence accounts suggest that anger and disgust are interchangeable expressions of condemnation, sociofunctional accounts suggest that they have distinct antecedents and consequences. We tested these accounts by investigating whether anger and disgust vary depending on the costs imposed by moral violations and whether they differentially correspond with aggressive tendencies...
