background Studies of endovascular renal denervation (RDN) have demonstrated significant blood pressure reduction in eligible patients with resistant hypertension. These trials have used stringent inclusion and exclusion criteria in patient enrollment, potentially selecting for a small subset of patients with resistant hypertension. In this study, we examined the changes in estimated prevalence of resistant hypertension when using increasingly stringent definitions of resistant hypertension in a fixed population and assessed the generalizability of RDN when applying study criteria to a community-based hypertensive population.

In this paper a low cost rectangular ring monopole antenna element and antenna array with parasitic patches are presented for ultra‐wideband applications. The proposed antenna element and antenna array are constructed with a modified partial ground plane on FR4 epoxy substrate with relative permittivity 4.4 and thickness 1.5 mm. A parametric study on the main parameters of the radiating elements and the distance between them as well as the partial ground has been investigated to optimize the design of the antenna array. The return loss is less than −10 dB in the frequency range 3.6–9.6 GHz which makes it suitable for UWB applications. Impedance and radiation characteristics of the proposed antenna are simulated using Ansoft HFSS 13 software. The simulated and measured results show good agreement and validate the proposed approach. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2268–2273, 2016

A field experiment was carried out during the two successive seasons of 2012/2013 and 2013/2014 to study the effect of compost and biofertilizers, as well as, some vitamins and their interaction on Gladiolus grandiflorus cv. Carmen plant. Results showed that vegetative growth (leaf length, number of leaves/plant and dry weight of leaves/plant), flowering aspects (length of spike, number of florets/spike and lower floret diameter) and corms productivity (corm diameter, corm dry weight and number of cormels per plant) were gradually increased by increasing the level of compost fertilizer. All biofertilizers and vitamins treatments significantly increased all vegetative growth characters, flowering parameters and corm and cormels productivity in comparison with the control. Effective microorganisms (E.M.) + active dry yeast (A.Y.) treatment seemed to be more effective than other treatments in this concern. The use of high level of compost (21 ton/fed) in combination with combined biofertilizers noticeably improved the different vegetative growth characters, flowering parameters and corms productivity of gladiolus.

Infections from coxsackie B2 viruses often cause viral myocarditis and, only rarely, multisystem organ impairment. We present the unusual case of a 42-year-old man in whom coxsackie B2 virus infection caused multiorgan infection, necessitating distal pancreatectomy, splenectomy, renal dialysis, and venoarterial extracorporeal membrane oxygenation with mechanical ventilation. In addition, the patient had a rapid-eye-movement sleep–related conduction abnormality that caused frequent sinus pauses of longer than 10 s, presumably due to myocarditis from the coxsackievirus infection. He recovered after permanent pacemaker placement and was discharged from the hospital. We discuss our aggressive supportive care and the few other reports of multiorgan impairment from coxsackieviruses.
