Diagnosis and Management of Supine and Nocturnal Hypertension in Orthostatic Hypotension: A Review.

The prevalence of supine and nocturnal hypertension (S-N-HT) is high among patients with orthostatic hypotension (OH), especially in those who have a neurogenic aetiology. The evidence suggests that S-N-HT exacerbates OH, although it is unclear whether pharmacologic treatment of S-N-HT will improve OH. S-N-HT has also been associated with target organ damage.

Removal of hydroquinone from water by electrocoagulation using flow cell and optimization by response surface methodology.

In this study, hydroquinone was removed from water by electrocoagulation using flow electrolyzer in mono polar and bipolar configurations in a batch recirculation mode of operation. Treatment performances of such effluents have been evaluated in terms of chemical oxygen demand removal. The effect of important operating parameters such as current density, flow rate, concentration of hydroquinone and supporting electrolyte on the pollutant removal and energy consumption is critically evaluated.
