Abhishek Aggarwal, David Feldman, Brian J Feldman
Several epidemiological studies have found that low vitamin D levels are associated with worse prognosis and poorer outcomes in patients with breast cancer (BCa), although some studies have failed to find this association. In addition, prior research has found that BCa patients with vitamin D deficiency have a more aggressive molecular phenotype and worse prognostic biomarkers. As vitamin D deficiency is common in patients diagnosed with BCa, elucidating the cause of the association between poor outcomes and vitamin D deficiency promises to have a significant impact on improving care for patients with BCa including enabling the development of novel therapeutic approaches...

Jane L Ireland, Philip Birch, Johann Kolstee, Alison Ritchie
This study examines partner abuse in LBGTI relationships, with focus on the associations with emotional distress and protective factors. Two hundred and eighty-seven participants took part. Partner abuse (victimisation) comprised three factors; conflict orientated aggression; hostile ignorance and control of communication; and social control and possessiveness (including threats to possessions). Perpetration factors were similar. Significant differences across sexuality or gender were limited to the perpetration of abuse relating to suspicion and possessiveness, where men were more likely to report this than the other gender groups, and women were less likely to report this...

This review covers the field of olfaction and chemosensation of odorants and puts this information into the context of interactions between microbes and behaviour; the microbiome-gut-brain axis (MGBA). Recent emphasis has also been placed on the concept of the holobiome which states that no single aspect of an organism should be viewed separately and thus must include examination of their associated microbial populations and their influence. While it is known that the microbiome may be involved in the modulation of animal behaviour, there has been little systematized effort to incorporate into such studies the rapidly developing knowledge of the wide range of olfactory systems...

BACKGROUND: Children who experience multiple adversities, such as prenatal exposure to drugs and poverty, early in development are at increased risk for the early initiation of alcohol and cigarette use. However, studies that examine potentially malleable processes associated with substance use initiation in the context of exposure to cumulative stressors are scant. This study examined associations between cumulative contextual risk at birth and initiation of alcohol and cigarette use in adolescence, testing childhood peer marginalization and peer aggression and behavior problems as mediating mechanisms...

The opioid epidemic in the United States is unprecedented and continues to worsen. Many opioid abusers obtain their pills through legitimate prescriptions, directly or indirectly, from a medical provider. While practitioners have a responsibility to treat pain, it is now becoming clear that aggressive opioid prescription practices contribute to an epidemic of abuse. The medical community has to balance the unintended consequences of opioid misuse and abuse with the need to provide adequate pain control. Additionally, providers are being held accountable by the legal system and professional organizations for their prescribing practices...

When intentionally pushed or insulted, one can either flee from the provoker or retaliate. The implementation of such fight-or-flight decisions is a central aspect in the genesis and evolution of aggression episodes, yet it is usually investigated only indirectly or in nonsocial situations. In the present fMRI study, we aimed to distinguish brain regions associated with aggressive and avoidant responses to interpersonal provocation in humans. Participants (thirty-six healthy young women) could either avoid or face a highly (HP) and a lowly (LP) provoking opponent in a competitive reaction time task: the fight-or-escape (FOE) paradigm...

REVIEW

Mitochondria-shaping proteins control the dynamic equilibrium between fusion and fission of the mitochondrial network. Their balance is strictly required to regulate various processes, including the quality of mitochondria, cell metabolism, cell death, proliferation and cell migration. Alterations in these processes are frequently encountered in cancer, during both its onset and later progression, as evidence emerge connecting alterations in mitochondrial dynamics with cancer development. In recent years, novel therapeutic approaches to fight against different human tumors aim at exploiting the immune system's ability to specifically recognize tumor antigens, thus killing malignant cells in a process named immune-surveillance...

BACKGROUND: This study tested a moderated-mediational model whereby dimensions of impulsivity (i.e., negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance) differentially predict perpetration of physical intimate partner aggression through problematic drinking in intoxicated and non-intoxicated heavy drinkers. METHODS: Participants were 249 heavy drinkers (148 men and 101 women) with a recent history of psychological and/or physical intimate partner aggression perpetration toward their current partner recruited from two metropolitan U...

REVIEW

Fungi, like other organisms, actively sense the environmental light conditions in order to drive adaptive responses, including protective mechanisms against the light-associated stresses, and to regulate development. Ecological niches are characterized by different light regimes, for instance light is absent underground, and light spectra from the sunlight are changed underwater or under the canopy of foliage due to the absorption of distinct wavelengths by bacterial, algal and plant pigments. Considering the fact that fungi have evolved to adapt to their habitats, the complexities of their 'visual' systems may vary significantly...

Although community violence is an established risk factor for youth aggression, less research has examined its relation with internalizing psychopathology. This study examined associations of community violence exposure with internalizing symptoms, and state and trait emotion dysregulation as mechanisms underlying these associations, in 287 adolescents aged 16-17 (45.6% male; 40.8% White). Community violence exposure was associated with internalizing symptoms, negative affect during peer evaluation, trait emotional reactivity, and infrequent problem solving...

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...

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...
