The effects of H2 gas treatment of an agricultural soil cultivated previously with a mixture of clover (Trifolium pratense) and alfalfa (Medicago sativa) on CO2 dynamics and microbial activity and composition were analyzed. The H2 emission rate of 250 nmol H2 g K1 soil h was similar to the upper limit of estimated H2 amounts emitted from N2 fixing nodules into the surrounding soil ([Dong, Z., L...

Blood pressure–lowering therapy reduces left ventricular mass, but the question of whether differences exist among drug classes has not been fully resolved. Our aim was to compare the effects of diuretics, -blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin receptor blockers on left ventricular mass regression in patients with hypertension on the basis...

The contributions of histamine (H, or Hj) receptor-mediated responses and, therefore, the effects of histamine blocking agents are unclear with regard to regulation of proximal epicardial and distal resistance coronary arteries. This study was designed to evaluate the effects of selective H,and Hj-receptor antagonists on epicardial and resistance vessels in the closed chest dog model. Histamine...

BACKGROUND The utility of esophagogastroduodenoscopy (EGD) performed at the time of percutaneous endoscopic gastrostomy (PEG) is unclear. We examined whether EGD at time of PEG yielded clinically useful information important in patient care. We also reviewed the outcome and complication rates of EGD-PEG performed by trauma surgeons. METHODS Retrospective review of all trauma patients undergoi...

Since the 2007 discovery that molecular hydrogen (H2) has selective antioxidant properties, multiple studies have shown that H2 has beneficial effects in diverse animal models and human disease. This review discusses H2 biological effects and potential mechanisms of action in various diseases, including metabolic syndrome, organ injury, and cancer; describes effective H2 delivery approaches; an...

BACKGROUND In elderly hemodialysis (HD) patients, the risk of medication-related problems is particularly high. Thus, certain medications should generally not be prescribed to those patients. The Beers criteria for potentially inappropriate medications (PIMs) have been publicized. Still, with regard to elderly HD patients, the prevalence and risk factors for prescription of PIMs are unknown. ...

Blood pressure-lowering therapy reduces left ventricular mass, but the question of whether differences exist among drug classes has not been fully resolved. Our aim was to compare the effects of diuretics, beta-blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin receptor blockers on left ventricular mass regression in patients with hypertension on the b...
