Stretching the limits of automated symbolic orienting.

Arrows trigger reflexive shifts of attention and instantiate the prototypical example of automated symbolic orienting. We conducted four experiments to further test the boundary conditions of this phenomenon. Participants discriminated a peripheral target while spatially uninformative arrows, pointing leftwards or rightwards, appeared at fixation.

N acetyl-transferases required for iron uptake and aminoglycoside resistance promote virulence lipid production in .

Unlabelled: Phagosomal lysis is a key aspect of mycobacterial infection of host macrophages. Acetylation is a protein modification mediated enzymatically by N-acetyltransferases (NATs) that impacts bacterial pathogenesis and physiology. To identify NATs required for lytic activity, we leveraged a nontubercular pathogen and an established model for hemolysis is a proxy for phagolytic activity.

An Uncommon Case of Pediatric Nasopharyngeal Carcinoma with Bone Metastases and Enchondromas Evaluated Using F-FDG PET/CT.

Nowadays, the utility of positron emission tomography/computed tomography (PET/CT) is well established in nasopharyngeal carcinoma (NPC). The incidence of NPC in the West population, especially in children, is very low. We present the first Italian case of a pediatric patient with NPC followed up with F-fluorodeoxyglucose (F-FDG) PET/CT scan in addition to the standard follow-up imaging methods, including CT and magnetic resonance imaging.

Internet use by pregnant women during prenatal care.

Objective: The search for medical information on the internet is a part of people's daily lives. Exponential volumes of data are available through various media and platforms. There are several problems related to the ease of creating and accessing medical information on the internet, as evidenced by the quantity of false content and increasing anxiety due to the consumption of these data.

Testing the effects of gaze distractors with invariant spatial direction on attention cueing.

In four experiments, we tested the boundary conditions of gaze cueing with reference to the resistance to suppression criterion of automaticity. Participants were asked to respond to peripheral targets preceded by a central gaze stimulus. Under one condition, gaze direction was random and uninformative with respect to target location (intermixed condition), as in the typical paradigm.
