Brucella alters the immune response in a prpA-dependent manner

High-definition tDCS alters impulsivity in a baseline-dependent manner

In intertemporal choice (ITC), people discount future rewards in proportion to the time delay until reward receipt. Despite recent non-invasive brain stimulation studies suggesting a general causal link between dorsolateral prefrontal cortex (dlPFC) activity and ITC impulsivity, results regarding the functional specificity of dlPFC are mixed. We used high-definition transcranial direct current ...

Prevalence of proline racemase/ hydroxyproline epimerase gene in human brucella isolates in Iran

Background: Human brucellosis is a zoonotic disease caused by Brucella melitensis, Brucella abortus, and Brucella suis. Brucella causes a chronic disease, which subverts the immune defense system of their hosts. In this study, the prevalence of an important Brucella virulence determinant, PrpA, which can modulate immune response, was determined in human isolates. Methods: Polymerase chain reac...

Umbelliprenin, a bioactive constituent from the genus Ferula has cytotoxic and apoptotic activity in a dose- and time-dependent manner

Exhaustive Exercise Alters Thinking Times in a Tower of London Task in a Time-Dependent Manner

Purpose: In contrast to other aspects of executive functions, acute exercise-induced alterations in planning are poorly investigated. While only few studies report improved planning performances after exercise, even less is known about their time course after exhaustive exercise. Methods: One hundred and nineteen healthy adults performed the Tower of London (ToL) task at baseline, followed by a...

Medium-dependent activity of immune serum on Brucella-infected macrophages.

Medium constituents affect the inhibitory action of anti-Brucella melitensis serum during in vitro infection of oil-induced peritoneal macrophages of the guinea pig with B. melitensis.
