BACKGROUND: Invasive apocrine adenocarcinoma (AAC) of breast is a rare histopathological subtype of breast carcinomas. We aim to investigate the different characteristics and prognostic outcomes between AAC and invasive ductal carcinoma (IDC) of breast cancer. RESULTS: AAC patients presented with older ages, more aggressive behaviors, lower ER and PR proportions, higher HER2 amplification rates and less application of breast-conserving therapy and adjuvant chemotherapy compared to IDC patients...

BACKGROUND: Suicidal behavior (SB) is a major, worldwide health concern. To date there is limited understanding of the associated motivational aspects which accompany this self-initiated conduct. AIMS: To develop a method for identifying motivational features associated with SB by studying admitted psychiatric patients, and to examine their clinical relevance. METHODS: By performing a factor analytic study using data obtained from a patient sample exhibiting high suicidality and a variety of SB methods, Motivations for SB Scale (MSBS) was constructed to measure the features...

INTRODUCTION: Benign bone tumors are heterogeneous and have different biological behaviors. Treatment requires knowledge of the principle diagnosis and clinical behavior to avoid, on the one hand, overtreatment and, on the other hand, incorrect diagnosis of a potentially malignant tumor. METHODS: Bone tumors of stage I (according to Enneking) should be observed clinically and radiologically. For stage II and stage III lesions, a biopsy should be performed, based on the corresponding oncological guidelines...

Prostate cancer (PCa) growth is mainly driven by androgen receptor (AR), and tumors that initially respond to androgen deprivation therapy (ADT) or AR inhibition usually relapse into a more aggressive, castration resistant stage (CRPC). Circulating growth hormone (GH) has a permissive role in PCa development in animal models and in human PCa xenograft growth. As GH and GH receptor (GHR) are both expressed in PCa cells, we assessed whether prostatic GH production is linked to AR activity and whether GH contributes to the castration resistant phenotype...

Alzheimer's disease (AD) is a terminal, age-related neurological syndrome exhibiting progressive cognitive and memory decline, however AD patients in addition exhibit ancillary neuropsychiatric symptoms (NPSs) and these include aggression. In this communication we provide recent evidence for the mis-regulation of a small family of genes expressed in the human hippocampus that appear to be significantly involved in expression patterns common to both AD and aggression. DNA array- and mRNA transcriptome-based gene expression analysis and candidate gene association and/or genome-wide association studies (CGAS, GWAS) of aggressive attributes in humans have revealed a surprisingly small subset of six brain genes that are also strongly associated with altered gene expression patterns in AD...

OBJECTIVES: To examine whether chronic physical aggression (CPA) in adulthood can be epigenetically programmed early in life due to exposure to early-life adversity. METHODS: Literature search of public databases such as PubMed/MEDLINE and Scopus. RESULTS: Children/adolescents susceptible for CPA and exposed to early-life abuse fail to efficiently cope with stress that in turn results in the development of CPA later in life. This phenomenon was observed in humans and animal models of aggression...

Animals are born with a rich repertoire of robust behaviors that are critical for their survival. However, innate behaviors are also highly adaptable to an animal's internal state and external environment. Neuromodulators, including biogenic amines, neuropeptides, and hormones, are released to signal changes in animals' circumstances and serve to reconfigure neural circuits. This circuit flexibility allows animals to modify their behavioral responses according to environmental cues, metabolic demands, and physiological states...

Epidermodysplasia verruciformis (EV) is a rare genodermatosis associated with susceptibility to beta-human papilloma virus (HPV) infection. EV patients develop disseminated warts and non-melanoma skin cancer, mainly squamous cell carcinomas (SCC) that are locally aggressive. EV pathogenesis is not yet fully understood, but alterations in the p16 gene play a role in the pathogenesis of neoplasms caused by high-risk genital HPV. To explore its role in EV lesions, we compared p16 expression in SCC from patients with and without EV...

Calcifying epithelial odontogenic tumour also known as Pindborg tumour, is a rare benign odontogenic neoplasm of locally aggressive behavior. It is thought to arise from the epithelial element of the enamel origin which are reminiscent of the cells in the stratum intermedium layer of enamel organ in tooth development. The tumour is characterized histologically by the presence of polygonal epithelial cells, calcifications and eosinophilic deposits resembling amyloid. Non-calcifying epithelial odontogenic tumours are very rare and unusual...

Kin selection theory predicts that, where kin discrimination is possible, animals should typically act more favorably toward closer genetic relatives and direct aggression toward less closely related individuals. Contrary to this prediction, we present data from an 18-y study of wild banded mongooses, Mungos mungo, showing that females that are more closely related to dominant individuals are specifically targeted for forcible eviction from the group, often suffering severe injury, and sometimes death, as a result...

Pancreatic ductal adenocarcinoma (PDAC) is an extremely aggressive neoplasm, predicted to become the second leading cause of cancer-related deaths before 2030. This dismal trend is mainly due to lack of effective treatments against its metastatic behavior. Therefore, a better understanding of the key mechanisms underlying metastasis should provide new opportunities for therapeutic purposes. Genomic analyses revealed that aberrations that fuel PDAC tumorigenesis and progression, such as SMAD4 loss, are also implicated in metastasis...

The pericytic (perivascular myoid cell) family of tumors is a distinctive group of mesenchymal neoplasms encountered in superficial sites and only rarely seen in viscera. The pericytic family subtends a spectrum of lesions, namely, glomus tumors and variants; myopericytoma, including myofibroma; and angioleiomyoma. In light of the contemporary classification of pericytic lesions, we identified and reviewed 17 cases of renal pericytic tumors from the files of 6 referral centers. These tumors presented over an age range of 17 to 76years (mean 46...

BACKGROUND: The Parent PARQ/Control (short version) for mothers and fathers is an inventory of 29 items where parents record their acceptance-rejection and control behaviors towards their children. Despite vast research on IPARQTheory, it has yet to be vali-dated for a Spanish population. The goal of this study is to analyze the psychometric properties of the instrument and its factorial structure. METHOD: Participants were 4,168 parents from the Principality of Asturias (2,166 mothers and 2,002 fathers)...

Research on neural androgen receptors (ARs) has traditionally focused on brain regions that regulate reproductive and aggressive behaviors, such as the hypothalamus and amygdala. Although many cells in the prefrontal cortex (PFC) also express ARs, the number of ARs per cell appears to be much lower, and thus, AR immunostaining is often hard to detect and quantify in the PFC. Here, we demonstrate that biotin tyramide signal amplification (TSA) dramatically increases AR immunoreactivity in the rat brain, including critical regions of the PFC such as the medial PFC (mPFC) and orbitofrontal cortex (OFC)...

There is extensive research evidence indicating that children and youth are the most vulnerable population for developing psychological symptoms relating to war and terror. Although studies have documented a wide range of detrimental emotional and behavioral effects of such exposure, much less is known about the effects of exposure to a continuous security threat for children and adolescents. Against this background, the current article examined the implications of continuous exposure to missile attacks among 1096 children and adolescents enrolled in public schools near the Israeli border with Gaza...

Patients with Autism Spectrum Disorder present with a heterogeneous mix of features beyond the core symptoms of the disorder. These features can be emotional, cognitive or behavioral. Behavioral symptoms often include self-injury, and this may take the form of repetitive skin-picking. The prevalence of skin-picking disorder in Autism is unknown. Skin-picking may lead to significant medical and psychosocial complications. Recent data suggest that behavioral interventions may be more effective than medications at reducing skin-picking in neurotypical patients...

Neuroendocrine tumors (NET) are often metastatic at the time of diagnosis. Metastatic well-differentiated (G1/G2) NET may display a wide range of behaviors, ranging from indolent to aggressive, even within apparently homogeneous categories. Thus, selecting the optimal treatment strategy is a challenging task. Somatostatin receptor imaging (SRI) is the standard molecular imaging technique for well-differentiated NET. When performed with (68)Ga-labeled somatostatin analogs (SRI-PET), it offers exquisite sensitivity for disease staging...

Upon hearing a conspecific signal, animals must assess their relationship with the signaller and respond appropriately. Territorial animals usually respond more aggressively to strangers than neighbors in a phenomenon known as the "dear enemy effect". This phenomenon likely evolved because strangers represent a threat to an animal's territory tenure and parentage, whereas neighbors only represent a threat to an animal's parentage because they already possess a territory (providing territory boundaries are established and stable)...

BACKGROUND: Some people are highly motivated to seek aggressive encounters, and among those who have been incarcerated for such behavior, recidivism rates are high. These observations echo two core features of drug addiction: high motivation to seek addictive substances, despite adverse consequences, and high relapse rates. Here we used established rodent models of drug addiction to determine whether they would be sensitive to "addiction-like" features of aggression in CD-1 mice. METHODS: In experiments 1 and 2, we trained older CD-1 mice to lever press for opportunities to attack younger C57BL6/J mice...

Here we review the principles based on which aggression is rendered abnormal in humans and laboratory rodents, and comparatively overview the main methodological approaches based on which this behavior is studied in the two categories of subjects. It appears that the discriminating property of abnormal aggression is rule breaking, which renders aggression dysfunctional from the point of view of the perpetrator. We show that rodent models of abnormal aggression were created by the translation of human conditions into rodent equivalents, and discuss how findings obtained with such models may be "translated back" to human conditions when the mechanisms underlying aggression and its possibilities of treatment are investigated...
