Blood pressure and serum potassium levels in hypertensive patients receiving or not receiving antihypertensive treatment.

Objective: Serum potassium has a fundamental role in blood pressure (BP) regulation, and there is evidence highlighting the importance of potassium homeostasis in hypertension. The aim of this study was to determine the relationship between serum potassium levels and office BP in untreated essential hypertensives and the effect of antihypertensive medication on serum potassium levels.

Setting And Participants: In a retrospective analysis, we collected data for consecutive patients first visiting our Hypertension Clinic from 1999-2004.

The effects of marathon swimming on serum leptin and plasma neuropeptide Y levels.

It seems likely that the neuropeptide Y (NPY)-leptin axis is involved in the regulation of energy expenditure in man. The purpose of this study was to observe the effect of a model of intense prolonged exercise-mediated energy expenditure (25 km swim race in 6.9-10.

A phase III study of 5-fluorouracil versus 5-fluorouracil plus interferon alpha 2b versus 5-fluorouracil plus leucovorin in patients with advanced colorectal cancer: a Hellenic Cooperative Oncology Group (HeCOG) study.

We conducted a phase III study in patients with advanced colorectal carcinoma (ACC). The total number of patients randomized from October 1993 until July 1998 was 192, whereas therapy was started on 179 and 158 (82.3%) have been evaluable.
