The basolateral amygdala (BLA) is implicated in responding to affective stimuli. Dopamine (DA) is released in the BLA during numerous conditions; however, the neurophysiological effects of DA in the BLA have not been examined in depth. In this study, the effects of DA receptor manipulation on spontaneous and afferent-driven neuronal firing were examined using in vivo extracellular single-unit r...

BACKGROUND During the last decade, the prevalence of carbapenem-resistant Enterobacteriaceae in human patients has increased. Carbapenemase-producing bacteria are usually multidrug resistant. Therefore, early recognition of carbapenemase producers is critical to prevent their spread. OBJECTIVES The objective of this study was to develop the primers for single and/or multiplex PCR amplificatio...

OBJECTIVES To report the identification of the metallo-beta-lactamase (MBL) variant VIM-19 in a Klebsiella pneumoniae clinical strain co-producing KPC-2 carbapenemase, CMY-2 cephalosporinase and CTX-M-15 extended-spectrum beta-lactamase. METHODS MICs were determined by agar dilution. Phenotypic tests were performed to detect carbapenemase production. PCR and nucleotide sequencing were used fo...

Among 603 isolates of Enterobacteriaceae collected between June and November 2003 from three university hospitals within Korea, bla(CTX-M-3), bla(CTX-M-15), bla(CTX-M-14), and bla(CTX-M-9) were detected in 41 isolates of species from five different genera of Enterobacteriaceae, Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii, Enterobacter spp., and Serratia marcescens.

We evaluated the presence of various Beta-lactamase genes within the bacteriophages in sewage. Results showed the occurrence of phage particles carrying sequences of bla(OXA-2), bla(PSE-1) or bla(PSE-4) and bla(PSE)-type genes. Phages may contribute to the spread of some Beta-lactamase genes.

Both the nucleus accumbens (NAc) and basolateral amygdala (BLA) contribute to learned behavioral choice. Neurons in both structures that encode reward-predictive cues may underlie the decision to respond to such cues, but the neural circuits by which the BLA influences reward-seeking behavior have not been established. Here, we test the hypothesis that the BLA drives NAc neuronal responses to r...

There is strong evidence that two cerebral hemispheres are differentially involved in emotional memory and that amygdala is a key subcortical structure for emotional experience. The present research investigated the possible involvement of lateralization of basolateral amygdala (BLA) and central amygdala (CEA) in place avoidance memory. For this purpose, male Long-Evans rats (280-320 g) were im...

The mechanisms of antimicrobial resistance were characterized in 90 Salmonella enterica isolates either resistant or with intermediate resistance to amoxicillin/clavulanate (AMC(R/I)) or resistant to third-generation cephalosporins (C3G(R)). These isolates were recovered in three Spanish hospitals during 2007-2009. The C3G(R) phenotype was expressed by three isolates that carried the following ...

The orbital and medial prefrontal cortex (OMPFC) receives inputs from the CA1/subicular (CA1/S) region of the ventral hippocampus and the basolateral nucleus of the amygdala (BLA). Despite many studies about these projections, little is known as to how CA1/S and BLA inputs converge and interact within the OMPFC. Extracellular recordings of single-unit activity in the OMPFC were performed in sod...

Introduction: It has been shown that administration of WIN55,212-2, a cannabinoid receptor agonist, into the basolateral amygdala (BLA), dose-dependently increases the thermal latency to withdrawal in the tail-.ick test and decreases pain related behaviors in both phases of the formalin test. Recent human and animal imaging data suggest that the nucleus accumbens (NAc) is an important neural su...
