We performed a randomized trial to compare the safety and efficacy of itraconazole with fluconazole in preventing fungal infections in patients undergoing allogeneic stem cell transplantation (SCT). Itraconazole (intravenous 200 mg daily, or oral solution 2.5 mg/kg 3 times daily) and fluconazole (intravenous or oral, 400 mg daily) were administered with the start of conditioning therapy, until ...

background: cuminum cyminum fruit essential oil (feo) dose-dependently can attenuate the expression of morphine tolerance and dependence in morphine-dependent mice. objective: in this study, the effects of cuminum cyminum feo on acquisition and expression of morphine-induced conditioned place preference (cpp) in morphine-sensitized mice were studied. methods: repeated subcutaneous (s.c.) admini...

Summary An important class of nonlinear weighted least‐squares problems arises from the assimilation observations in atmospheric and ocean models. In variational data assimilation, inverse error covariance matrices define weighting problem. For observation errors, a diagonal matrix (i.e., uncorrelated errors) is often assumed for simplicity even when errors are suspected to be correlated. While...

Fear conditioning is a widely used paradigm in non-human animal research to investigate the neural mechanisms underlying fear and anxiety. A major challenge in conducting conditioning studies in humans is the ability to strongly manipulate or simulate the environmental contexts that are associated with conditioned emotional behaviors. In this regard, virtual reality (VR) technology is a promisi...

Neuronal activity in medial prefrontal cortex (mPFC) is critical for the formation of trace fear memory, yet the cellular mechanisms underlying these memories remain unclear. One possibility involves the modulation of intrinsic excitability within mPFC neurons that project to the basolateral complex of amygdala (BLA). The current study used a combination of retrograde labeling and in vitro whol...

The immediate-early gene Arc is rapidly expressed in response to neuronal activity and is thought to be involved in mechanisms of synaptic plasticity. The function of Arc in these processes remains unknown. The present study demonstrates that during an in vitro neural correlate of eyeblink classical conditioning, there is a rapid and transient increase in levels of Arc protein that require acti...

The medial geniculate nucleus of the thalamus responds to auditory information and is a critical part of the neural circuitry underlying aversive conditioning with auditory signals for shock. Prior work has shown that lesions of this brain area selectively disrupt conditioning with auditory stimuli and that neurons in the medial geniculate demonstrate plastic changes during fear conditioning. H...

Global climate change increases heat loads in urban areas causing health and productivity risks for millions of people. Inhabitants in tropical and subtropical urban areas are at especial risk due to high population density, already high temperatures, and temperature increases due to climate change. Air conditioning is growing rapidly, especially in South and South-East Asia due to income growt...
