Recent studies have shown that perceiving the pain of others activates brain regions in the observer associated with both somatosensory and affective-motivational aspects of pain, principally involving regions of the anterior cingulate and anterior insula cortex. The degree of these empathic neural responses is modulated by racial bias, such that stronger neural activation is elicited by observ...

Historically, managers in livestock production have focused on production management; however, as operations have grown they have spent more time managing employees. Increased time spent overseeing employees brings additional risks and challenges, and, hence, a greater need for human resource management (HRM) skills. This study investigated HRM practices in pork production and analyzed their ri...

introduction: one of the most important reasons for postoperative pain is the extrusion of debris from the apical foramen during preparation and shaping of root canals. the aim of this clinical trial was to evaluate the severity of postoperative pain with the use of two different engine-driven niti systems. methods and materials: ninety mandibular molars were randomly divided into two groups ( ...

Social relationships affect empathy in humans such that empathic neural responses to perceived pain were stronger to racial in-group members than to racial out-group members. Why does the racial bias in empathy (RBE) occur and how can we reduce it? We hypothesized that perceiving an other-race person as a symbol of a racial group, rather than as an individual, decreases references to his/her pe...

Several theories suggest that people do not represent race when it does not signify group boundaries. However, race is often associated with visually salient differences in skin tone and facial features. In this study, we investigated whether race could be decoded from distributed patterns of neural activity in the fusiform gyri and early visual cortex when visual features that often covary wit...

introduction: the most important aims of root canal preparation are the removal of vital pulp tissue, remaining necrotic debris and infected dentin, eliminating the bulk of bacteria present in the root canal system. the aim of this study was to compare the cleaning efficacy of hand k-flexofiles and rotary race and k3 instruments in root canal preparation. materials and methods: a total of 60 si...
