“Purpose: We compared the effect of static magnetic field (SMF) and verapamil, a potent vascular calcium channel blocking agent, on sudden elevation in blood pressure in conjunction with arterial baroreflex sensitivity (BRS) and microcirculation.
Materials and methods: Forty-four experiments were performed on conscious rabbits sedated using pentobarbital intravenous (i.v.) infusion (5 mg kg(-1) h(-1)). Mean femoral artery blood pressure (MAP), heart rate, BRS and car lobe skin microcirculatory blood flow, estimated using microphotoelectric plethysmography (MPPG), VE-822 order were simultaneously measured after a 40 min exposure of the sinocarotid baroreceptors to 350 mT SMF, generated by Nd(2)-Fe(14)-B magnets, or 30 min of verapamil i.v. administration (20 mu g kg(-1) min(-1)). BRS was assessed from heart rate and MAP responses to i.v. bolus of nitroprusside and phenylephrine.
Results: The decrease in phenylephrine-induced abrupt elevation in MAP (Delta MAP(AE)) was significantly larger after verapamil than after SMF exposure. Delta MAP(AE) inversely correlated with
verapamil-induced significant increase in Delta MPPG (r = 0.53, p < 0.000) and with SMF-induced significant increase in Delta BRS (r = 0.47, p < 0.016).
Conclusions: Our results suggest that verapamil-potentiated vascular blood pressure buffering mechanism was more effective than SMF-potentiated baroreflex-mediated
blood pressure buffering mechanism, and a potential benefit of both approaches in cardiovascular conditions with abrupt high elevation in blood pressure.”
“We demonstrated that transmittance and field intensities of a thick metal sandwiched between two dielectric photonic crystals (PCs) can be enhanced by more than two orders of magnitude and by nearly 20 times, respectively, compared to a single metal layer with the same thickness. Under the tunneling mechanism, the light can enter the sandwiched structure without reflection and localizes at the two interfaces of the metal film and PCs. This configuration of fields facilitates Quisinostat purchase the reduction of absorption in the metal. Experimental results are in good agreement with simulations.

“Purpose: To investigate radiation-induced bystander responses and to determine the role of gap junction intercellular communication and the radiation environment in propagating this response.
Materials and methods: We used medium transfer and targeted irradiation to examine radiation-induced bystander effects in primary human fibroblast (AG01522) and human colon carcinoma (RKO36) cells.
