exposure to mercury (hg) as a heavy metal can cause health effects. the objective of this study was to assess occupational exposure to hg in a chlor-alkali petrochemical industry in iran by determining of hg concentrations in air, blood and urine samples.the study was performed on 50 exposed subjects and 50 unexposed controls. air samples were collected in the breathing zone of exposed subjects...
background: hypertension is one of the most important, non-contagious diseases. every year many people either die or suffer from it. therefore, the first step is to screen prehypertensive people and change the manner of their life style. nowadays, prayer in complementary alternative medicine (cam) is known as an important factor in changing people's lives. this study is done with the goal of de...
Background: Previous studies demonstrated a health improving effect in patients underwent an automatic vibratory massage taking 10 minutes. One of reasons that may explain a healing effect of the automatic massage is a stimulated increase in both blood circulation through vascular system and effective size of blood vessels. Objective: This paper aims to quantify a contribution of the auto...

background: coarctation of the aorta (coa) is a defect that accounts for 5-8% of all congenital heart diseases. balloon angioplasty as a treatment for coa is increasingly performed, with endovascular stents having been proposed as a means of improving the efficacy and safety of the procedure. the aim of this study was to evaluate the systolic blood pressure gradient at rest and during maximal e...
Mercury (Hg) causes hazardous cumulative effects in humans; like central nervous system disorders,hypertension and chromosomal aberrations. Therefore, due to high toxicity and bioaccumulationfactor, mercury determination and speciation in human blood is very important. A sensitive,accurate, precise and inexpensive method was demonstrated for preconcentration and speciationof ultra-trace mercury...
Introduction: Hypertension is one of the most important preventable risk factors for cardiovascular disease. This observational study aimed to depict the role of regular blood donation on the systolic and diastolic blood pressure (SBP and DBP, respectively) in hypertensive patients in comparison with normotensive people. Methods: This study was performed as a cross-sectional descriptive study ...
OBJECTIVE To assess whether using intensive blood pressure targets leads to lower blood pressure in a community population of people with prevalent cerebrovascular disease. DESIGN Open label randomised controlled trial. SETTING 99 general practices in England, with participants recruited in 2009-11. PARTICIPANTS People with a history of stroke or transient ischaemic attack whose systolic ...
BACKGROUND Twenty-four hour ambulatory blood pressure thresholds have been defined for the diagnosis of mild hypertension but not for its treatment or for other blood pressure thresholds used in the diagnosis of moderate to severe hypertension. We aimed to derive age and sex related ambulatory blood pressure equivalents to clinic blood pressure thresholds for diagnosis and treatment of hyperten...
