Deoxyhemoglobin values for the plantar metatarsal, arch, and heel angiosomes were significantly different between patients with and without PAD (P < .005). Mean deoxyhemoglobin values for the same three angiosomes showed significant buy APR-246 differences between patients with monophasic, biphasic, and triphasic waveforms (P < .05). In patients with PAD, there was also significant correlation between deoxyhemoglobin values and ABI for the same three angiosomes (P = .001). Oxyhemoglobin values did not predict the presence or absence

of PAD, did not correlate with PAD severity, and did not correlate with the ABI.

Conclusions: These results suggest the ability of hyperspectral imaging to detect the presence of PAD.

Hyperspectral measurements can also evaluate different severities of PAD. (J Vasc Surg 2011;54:1679-88.)”
“Electrolytic lesions of the commissural nucleus of the solitary tract (commNTS) in rats enhance the pressor response to bilateral carotid occlusion or to intravenous infusion of hypertonic NaCl without changing baroreflex responses. In an opposite direction, commNTS lesions abolish the pressor responses to peripheral chemoreflex activation. These opposite effects of commNTS lesions Citarinostat mouse apparently result from an impairment of sympathetic activation in one case and in a facilitation of vasopressin secretion in the others. In the present study, we investigated the effects of the electrolytic lesions of the commNTS in the pressor responses

that depend on sympathetic activation and vasopressin secretion produced by central cholinergic or adrenergic activation with intracerebroventricular (i.c.v.) injections of carbachol or noradrenaline, respectively, in unanesthetized rats. Male Holtzman rats (280-320g, n = 8-15/group) with acute (1 day) or chronic (21 days) sham or commNTS lesions (1 mA x 10 s) and a stainless steel cannula implanted find more in the lateral ventricle were used. Acute commNTS lesions increased the pressor response to i.c.v, injection of carbachol (0.5 nmol/1 mu 1) (52 +/- 2, vs. sham: 37 +/- 2 mmHg) or noradrenaline (80 nmol/1 mu 1) (45 +/- 6, vs. sham: 30 +/- 3 mmHg), whereas chronic commNTS lesions did not affect the pressor responses to the same treatments. Lesions of the commNTS impaired chemoreflex responses produced by intravenous KCN, without changing baroreflex responses. The results suggest that commNTS-dependent inhibitory signals are involved in the modulation of the pressor responses to central cholinergic and adrenergic activation, probably limiting vasopressin secretion.
