RESULTS: see more One hundred twenty patients with AFLUS underwent thyroidectomy; 18 (15%) had carcinoma. FSE altered management in 36 (62%) of the 58 patients-32 with benign disease and 4 with cancer who underwent lobectomy and total thyroidectomy, respectively. Total thyroidectomy without FSE was performed in 61 (51%) patients with sonographically. confirmed bilateral disease. FSE had a 36.4% sensitivity, 100% specificity, 100% positive predictive value, 87% negative predictive
value, and 88% accuracy. CONCLUSION: Ultrasound in combination with FSE is of value for determining the extent of thyroidectomy in patients with AFLUS. (C) 2015 Elsevier Inc. All rights reserved.”
“The amygdala is implicated in chronic pain-induced emotional changes. Chronic pain induces plastic
changes of the N-methyl-D-aspartate receptor (NMDAR) functions in the brain including the amygdala. D-Serine is synthesized endogenously by serine racemase and modulates NMDAR-mediated synaptic transmission as a coagonist of glycine binding site. To clarify the functional roles of endogenous CYT387 mouse D-serine in chronic pain-induced plasticity of NMDAR mediated synaptic transmission, we investigated the NMDAR-mediated excitatory synaptic current (EPSC) of neurons in the latero-capsular division of the central amygdala (CeLC) using brain slices from serine racemase knockout (SR-KO) mice with chronic pain induced by monoarthritis. The decay time of NMDAR-mediated EPSC was significantly elongated by monoarthritis in wild type (WT) mice, but not in SR-KO mice. The D-serine application-induced increase of NMDAR-mediated EPSC was significantly facilitated by monoarthritis in WT mice, but not in SR-KO mice. These results suggest that endogenous D-serine facilitates chronic pain-induced plastic
changes of NMDAR mediated synaptic transmission in CeLC. (c) 2012 Elsevier Ireland Ltd. All rights reserved.”
“Electrical stimulation of cutaneous tissue through surface electrodes is an often used method for evoking experimental pain. However, at painful intensities both non-nociceptive selleck screening library A beta-fibers and nociceptive A delta- and C-fibers may be activated by the electrical stimulation. This study proposes a finite element (FE) model of the extracellular potential and stochastic branching fiber model of the afferent fiber excitation thresholds. The FE model described four horizontal layers; stratum corneum, epidermis, dermis, and hypodermal used to estimate the excitation threshold of A beta-fibers terminating in dermis and A delta-fibers terminating in epidermis. The perception thresholds of 11 electrodes with diameters ranging from 0.2 to 20 mm were modeled and assessed on the volar forearm of healthy human volunteers by an adaptive two-alternative forced choice algorithm. The model showed that the magnitude of the current density was highest for smaller electrodes and decreased through the skin.
