However, to address the needs of large clinical trials and long-term monitoring, in which efficiency may compete with precision of measurement, we developed the 8-item self-administered SF-Qualiveen.

Materials and Methods: A total of 180 English speaking and French speaking outpatients with multiple sclerosis

at multiple sclerosis clinics and departments of rehabilitation in Canada and France completed the entire Qualiveen, the Multiple Sclerosis Quality of Life-54 questionnaire or its French version (SEP-59) as well as urinary function assessments at study enrollment and 2 to 10 weeks later. At visit 2 patients also made global ratings of change in urinary health related quality of life. SF-Qualiveen development and testing used this data set.

Results: Correlations selleckchem of SF-Qualiveen with its original form were high (r = 0.70 to 0.92). find more SF-Qualiveen proved reliable (ICC 0.83 to 0.93). Its responsiveness was similar to that of the long form (SRM 0.75 to 1.62).

Correlations with other measures were consistent with our a priori predictions (weighted kappa 0.55 for cross-sectional correlations and 0.66 for correlations of change), supporting the cross-sectional and longitudinal construct validity of SF-Qualiveen.

Conclusions: SF-Qualiveen has excellent measurement properties, similar to those of the long form. The new instrument is likely to perform well in the clinical and research context.”
“Synaptic plasticity depends on the generation, modification and disconnection of synapses. An excitatory synapse is connected to a specialized dendritic compartment called a spine, which undergoes activity-induced remodeling. Here, we discuss a signaling pathway that transduces neuronal activity into the remodeling of spine through p38 mitogen-activated protein kinase ( MAPK) and N-cadherin. Dendritic spines change their morphology and density in response to neuronal activity. In the early phase, posttranslational modifications of synaptic molecules regulate spine morphology, whereas activity-induced gene products reduce

spine density in the late phase. One of the targets of these mechanisms is N-cadherin. An activity-induced protocadherin, Tangeritin arcadlin, stimulates thousand and one 2 beta ( TAO2 beta) kinase, which in turn activates p38 MAPK through MAPK kinase 3 ( MEK3), resulting in the endocytosis of N-cadherin and the decrease in spine number. This pathway also underlies the mechanism of the spine decrease in neuronal disorders, such as Alzheimer’s disease and epilepsy. Development of new p38 MAPK inhibitors brings a ray of hope with respect to the development of more effective therapies for these patients.”
“Neurotrophic factors (NTFs) are a pleiotropic group of secreted growth factors that regulate multiple aspects of neuronal development, including the regressive event of cell death.
