Fiber-optic attraction of urinary stones during laser lithotripsy may be exploited to manipulate stone fragments inside the urinary tract without mechanical grasping tools, saving the urologist time and space in the ureteroscope working channel. We compare thulium fiber laser (TFL) high pulse rate/low pulse energy operation to conventional holmium:YAG low pulse rate/high pulse energy operation ...

The efficacy of single-agent chemotherapy for patients with low risk gestational trophoblastic neoplasia (LRGTN) with methotrexate or dactinomycin is well established, but efforts continue to reduce the toxicity, the patients time and cost of treatment. In a randomized clinical trial, we evaluated and compared the efficacy, toxicity and cost effectiveness of pulse-methotrexate versus pulse-dact...

bronchial breathing were present, and the diagnosis of lobar pneumonia was made. The pulse at the time was 9? p. m. Next morning the patient's temperature was 98.6? F., and the pulse rate 52. For the next six days the temperature was of the same type, viz., 102.5? F. in the evenings, and 98.5? F. in the mornings, with corresponding changes in the pulse rate. Crisis occurred on the seventh day, ...

Pulse diagnosis is important in oriental medicine. The purpose of this study is explaining the mechanisms of pulse with a cardiovascular simulator. The simulator is comprised of the pulse generating part, the vessel part, and the measurement part. The pulse generating part was composed of motor, slider-crank mechanism, and piston pump. The vessel part, which was composed with the aorta and a ra...

HEART RATE PARTICULARITIES IN CHRONIC OBSTRUCTIVE PULMONARY DISEASE (Abstract): Autonomic nervous system dysfunction proved in chronic obstructive pulmonary disease (COPD) patients might determine an elevated cardiovascular risk by heart rate alteration. Aim: To assess the particularities of heart rate as a possible cardiovascular risk factor in COPD patients. Materials and Methods: This prospe...

lead forms the complexes with xylenol orange in the basic solution. an adsorptivedifferential pulse stripping method for the determination of lead is proposed. the procedureinvolves an adsorptive accumulation of lead on a hanging mercury drop electrode (hmde) inthe presence of xylenol orange, followed by reduction of adsorbed lead by voltammetric scanusing differential pulse modulation. the opt...
