Lactating rats show less noise-induced freezing and fewer inhibitory responses on the 6th day post-delivery when submitted to water and food deprivation in a classical conflict paradigm. Lactating mice go more often to the illuminated chamber in a light-dark cage and stay longer in it than virgin females. The present study was designed to assess the influence of this physiological state, i.e. l...

Several findings have pointed to the role of histaminergic neurotransmission in the modulation of anxiety-like behaviors and emotional memory. The elevated plus-maze (EPM) test has been widely used to investigate the process of anxiety and also has been used to investigate the process of learning and memory. Visual cues are relevant to the formation of spatial maps, and as the hippocampus is in...

Epimorphin/syntaxin-2 (EPM) is a plasma membrane-anchored protein that has at least two distinct functions depending on its membrane topology: vesicle fusion when localized to the cytoplasmic surface and morphogenic signaling when localized to the extracellular surface. Transgenic mice that express full-length extracellular EPM fused to the NH2-terminal signal sequence of interleukin-2, under t...

This paper proposes the application to requirements elicitation of an innovative creativity technique based on a model of the pragmatics of communication, the Elementary Pragmatic Model (EPM). The EPM has been used to define a creative process, called EPMcreate that consists of sixteen steps. In each step, the problem is analyzed according to one elementary behavior identified by the EPM. Each ...

Equine protozoal myeloencephalitis (EPM) is a syndrome in which the inflammatory component of disease is an identifying criterion for histological diagnosis, but not addressed in clinical diagnosis or treatment. Two parasites, Sarcocystis neurona or Neospora hughesi, are generally believed to be the cause EPM in horses. Elucidating the nature of the immune response in EPM, determining how S neu...

Central pontine myelinolysis (CPM) and extrapontine myelinolysis (EPM) are well recognized syndromes related to the rapid correction of hyponatremia, which are reported to show brain stem signs and various movement disorders. Cognitive dysfunction and neuropsychological findings, however, have seldom been reported. Cognitive manifestations in osmotic myelinolysis may have been underestimated du...

Sarcocystis neurona is an apicomplexan parasite that can cause mortality in domestic and wild animals. It is an important cause of the neurological disease equine protozoal myeloencephalitis (EPM) in the Americas. Different surface antigen (SAG) phenotypes have been observed for S. neurona, and not all isolates of S. neurona contain the genes (SnSAG) to encode all SAGs. Recent studies indicate ...

INTRODUCTION Anxiety is among the most common and treatable mental disorders. Adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. The elevated plus-maze (EPM) has broadly been used to investigate anxiolytic and anxiogenic compounds. The present study investigated the effects of intraperitoneal (IP) injection of cannabinoid CB1 receptor antagonist (AM251) in...
