Interactions between and isolated from a case of diarrhea: evaluation of antimicrobial susceptibility and immune response of infected macrophages.

species cause a wide spectrum of human diseases, primarily gastroenteritis, septicemia, and wound infections. Several studies have shown that about 40% of these cases involve mixed or polymicrobial infections between spp. and bacteria from other genera.

Conflicts between priming and episodic retrieval: a question of fluency?

Human memory consists of different underlying processes whose interaction can result in counterintuitive findings. One phenomenon that relies on various types of mnemonic processes is the repetition priming effect for unfamiliar target faces in familiarity decisions, which is highly variable and may even reverse. Here, we tested the hypothesis that this reversed priming effect may be due to a conflict between target fluency signals and episodic retrieval processes.

Physiological and agronomical traits effects of titanium dioxide nanoparticles in seedlings of Solanum lycopersicum L.

Background: Titanium dioxide nanoparticles (TiO NPs) have been reported to have contrasting effects on plant physiology, while their effects on sugar, protein, and amino acid metabolism are poorly understood. In this work, we evaluated the effects of TiO NPs on physiological and agronomical traits of tomato (Solanum lycopersicum L.) seedlings.

Control over emotional facial expressions: Evidence from facial EMG and ERPs in a Stroop-like task.

Facial expressions carry important social signals that must be precisely regulated despite potentially conflicting demands on veridicality, communicative intent, and the social situation. In a sample of 19 participants we investigated the challenges of deliberately controlling two facial expressions (smiles and frowns) by the emotional congruency with the expressions of adult and infant counterparts. In a Stroop-like task requiring participants' deliberate expressions of anger or happiness, we investigated the impact of task-irrelevant background pictures of adults and infants showing negative, neutral, or positive facial expressions.

The other-race effect in facial expression processing: Behavioral and ERP evidence from a balanced cross-cultural study in women.

Although evidence for cultural variants in facial expression decoding is accumulating, the other-race effect in facial expression processing and its neural correlates are still unclear. We investigated this question with a fully balanced design, in which a group of East Asian and a group of European Caucasian women categorized pictures of sad, happy, angry, and neutral facial expressions posed by individuals of their own-race and the other-race. Results revealed a disadvantage in categorizing expressions of anger in other-race faces in both samples, and for sad expressions in the European sample only.
