Type III secretion systems identified in bacterial pathogens of animals and plants transpose effectors and toxins directly into the cytosol of host cells or into the extracellular milieu. Proteins of the type III secretion apparatus are conserved among diverse and distantly related bacteria. Many type III apparatus proteins have homologues in the flagellar(More)
Zeolites were synthesized from silica-rich (SF-Z) and calcium-rich (CF-Z) fly ashes, respectively, and their performance in immobilizing ammonium and phosphate was investigated through batch experiments. The cation exchange capacity and phosphate immobilization capacity of SF-Z were identified as 2.79 meq/g and 12.97 mg/g while those of CF-Z were 0.69 meq/g(More)
This randomized, double-blind, placebo-controlled study examines the effects of clonidine (a centrally acting sympathoinhibitor) on ventricular arrhythmias in 35 patients with congestive heart failure (CHF) by using the 24-h ambulatory electrocardiographic recording. After baseline examination and Holter recording, patients were balanced and 18 patients(More)
Congestive heart failure (CHF) is characterized by sympathetic activation and parasympathetic withdrawal, and the magnitude of sympathoneural activation is associated with adverse outcome. Angiotensin-converting enzyme inhibitor therapy has been shown to reduce mortality and improve prognosis in patients with CHF, but whether this therapy improves cardiac(More)
