It is well known from epidemiology that values of indices describing physiological state in a given age may influence human morbidity and mortality risks. Studies of connection between aging and life span suggest a possibility that dynamic properties of age trajectories of the physiological indices could also be important contributors to morbidity and mortality risks. In this paper we use data ...

objectives the aim of this study was to evaluate the biological effects of opium on the number of peripheral blood cells and red blood cells (rbcs) indices in diabetic rats. materials and methods peripheral blood samples were collected from diabetic, opium-addicted, diabetic opium-addicted and normal male and female rats and hematological parameters were measured. results the mean number of whi...

this study aimed at investigating the variations of blood pressure, heart rate and oxygen consumption and their relationship with body lipid profile in active and inactive students. 10 active students (mean age 21 yr, weight 68.1 kg and height 174.1 cm) and 10 inactive students (mean age 21.5 yr, weight 73.07 kg and height 177 cm) from shahid rajaee teacher training university who volunteered t...

The aim of this study was to evaluate, in a context of general inhibition of the sympathetic nervous system, the cerebral haemodynamic response to -30 degrees head-down tilt (HDT), a manoeuvre that produces an increase in intracranial arterial pressure. Nineteen healthy subjects were studied according to the following protocol: 10 min lying in supine position, 10 min HDT, 10 min recovery. Inhib...

PURPOSE The current study objective was to compare blood platelet indices in preterm newborns (PTN) and full term newborns (FTN). MATERIALS AND METHODS We introduced to our study 51 PTN (25 females, 26 males) and 55 FTN (25 females, 30 males). Platelet indices were estimated in blood samples collected from the umbilical artery. RESULTS PTN demonstrated a decreased count of blood platelets (...

Diffuse impairment of ventricular function after cardiac surgery may be related to the generation during reperfusion of the myocardium of free radicals derived from oxygen. Fifteen patients undergoing elective coronary bypass surgery were studied by previously described assays for peroxidised lipids and for isomerised lipids which were used as indices of free radical activity. Serial blood samp...

OBJECTIVES To determine the value of ankle and toe blood pressure indices and pedal pulse palpation in the assessment of peripheral arterial disease in subjects with type 2 diabetes mellitus (DM). DESIGN Cross-sectional study. SUBJECTS A convenience sample of 85 female subjects with type 2 DM underwent a series of peripheral vascular assessments at the diabetes clinic of a community hospita...

The present study aimed to investigate the applicability of Universal Thermal Climate Index (UTCI) as an innovative and science-based index in public health researches, in occupational heat stress assessment. All indoor and outdoor workers (200 people) of Brick industries of Shahroud, Iran participated in the research. First, the environmental variables such as air temperature, wet-bulb tempera...

To evaluate the utility of blood pressure variability (BPV) calculated using previously published and newly introduced indices using the variables falls and age as comparators.While postural hypotension has long been considered a risk factor for falls, there is currently no documented evidence on the relationship between BPV and falls.A case-controlled study involving 25 fallers and 25 nonfalle...

background: according to the high prevalence of cardiovascular diseases (cvd) in developing countries as well as high treatment expenses for patients and health-care systems, cvd prevention in such societies has a great importance. one of the most effective strategies is improvement of knowledge and attitude towards the cvd risk factors. this study aimed to evaluate the knowledge and attitude o...
