Neuronal rhythmic activities within thalamocortical circuits range from partially synchronous oscillations during normal sleep to hypersynchrony associated with absence epilepsy. It has been proposed that recurrent inhibition within the thalamic reticular nucleus serves to reduce synchrony and thus prevents seizures. Inhibition and synchrony in slices from mice devoid of the gamma-aminobutyric ...

xanthan gum is a microbial polysaccharide of great commercial importance as it has unusual rheological properties in solution and consequent range of applications. in this study, a series of mutants were isolated from xanthomonas campestris ptcc 1473 by ethyl methanesulfonate mutagenesis. the polysaccharide yield of one mutant, xc1473e2, was 30% better than that of the parent strain. it also sh...

Despite the importance and significant clinical impact of understanding information processing in the nociceptive system, the functional properties of neurons in many parts of this system are still unknown. In this work we performed whole cell patch-clamp recording in rat brain stem blocks to characterize the electrophysiological properties of neurons in the dorsal reticular nucleus (DRt), a re...

Neurons of the medial pontine reticular formation (mPRF) are involved in the execution of numerous behaviors including initiation of locomotion, eye movements, startle responses, and rapid eye movement sleep phenomena. Approximately half of the afferent projections to mPRF neurons come from within the reticular formation (Shammah-Lagnado et al., 1987). In spite of the importance of reticulo-ret...

The monocarboxylate transporter (MCT)-1 plays an important role in the transfer of monocarboxylate metabolites such as lactate, ketone bodies, and acetic acid. The present study revealed the selective localization of MCT1 in reticular cells of the murine lymph node. An intense MCT1 immunoreactivity was found in the reticular cells forming a cellular network together with sinus-lining cells in t...
