Researchers often have expectations about the research outcomes in regard to inequality constraints between, e.g., group means. Consider the example of researchers who investigated the effects of inducing a negative emotional state in aggressive boys. It was expected that highly aggressive boys would, on average, score higher on aggressive responses toward other peers than moderately aggressive...

This study reports on a population of early adolescent male sexual offenders 9 to 14 years of age compared with a clinic control group matched for age, sex, ethnic status, and the presence of a DSM-III-R conduct disorder. The sex offenders were found to exhibit a significant history of nonsexual antisocial behavior, physical and sexual abuse, and psychiatric comorbidity. The two groups did not ...

This study examined the relationship between biological and social risk factors and aggressive behavior patterns in an Australian high-risk sample of 370 adolescents. Perinatal, temperamental, familial, sociodemographic, and behavioral data were collected during interviews completed during pregnancy. immediately postpartum, and when the children were 6 months old and 5, 14, and 15 years old. Yo...

Arthroscopic inside-out and outside-in meniscus repair techniques are technically demanding. The need for additional incisions with the risk of iatrogenic neurovascular damage can lead to prolonged intraoperative and tourniquet time and can thereby increase morbidity and anesthesia costs. To overcome these disadvantages, all-inside repair devices were developed. Simple insertion of these rigid ...

Because stingrays are ubiquitous in all temperate and tropical oceans worldwide, and ev...

Angiofibrolipoma is a histological variant of lipoma, which commonly occurs in subcutaneous tissues. In the present report we illustrate the case of an angiofibrolipoma of the posterior upper mediastinum in a 75-year-old man presented with progressive chest pain. Xray chest showed a homogeneous opacity vertically oriented along the right lateral aspect of thoracic vertebrae with an obtuse angle...

Tumor cells display progressive changes in metabolism that correlate with malignancy, including development of a lipogenic phenotype. How stored fats are liberated and remodeled to support cancer pathogenesis, however, remains unknown. Here, we show that the enzyme monoacylglycerol lipase (MAGL) is highly expressed in aggressive human cancer cells and primary tumors, where it regulates a fatty ...

We investigated the reliability and (convergent and discriminant) validity of an observational measure of physical aggression in toddlers and preschoolers, originally developed by Keenan and Shaw [1994]. The observation instrument is based on a developmental definition of aggression. Physical aggression was observed twice in a laboratory setting, the first time when children were 1-3 years old,...

The computed tomographic (CT) findings in aggressive or invasive meningiomas have been described by several authors [1-3]. These signs include heterogeneous contrast enhancement with or without cystic components, irregular tumor margins , and marked surrounding edema. Recently , "mushrooming" has been added as an additional CT finding [4]. According to Taveras and Wood [5], the angiographic dem...
