BACKGROUND/AIM Exercise can positively influence risk factors associated with cardiovascular disease. The mechanisms by which exercise reduces atherogenic risk remain unknown. The aim of the present study was to investigate the effect of acute exercise (cardiopulmonary exercise cycle ergometer test) on atherogenic lipids in untreated mild hypertensive patients with or without hypercholesterolem...

OBJECTIVES The Baltimore Therapeutic Equipment (BTE) work simulator is routinely used by occupational therapists in functional capacity evaluation. Currently, there is a lack of normative data for various attachments on this instrument. The purposes of this study were to (a) establish norms for the biomechanical and physiological responses during three tasks on the BTE work simulator, namely, w...

OBJECTIVE To determine the pattern of the abnormal ventilatory response in heart failure and how it relates to symptoms by looking at tidal volume (VT) and frequency (f) during exercise. METHODS 45 patients with heart failure and 21 controls underwent maximal treadmill based exercise testing with metabolic gas exchange analysis. The relation of ventilation (VE) to VT was plotted to look for a...

Background: Blood gas and acid base values are very much essential for health assessment disease diagnosis of captive elephants especially when clinical signs were nonspecific other diagnostic techniques may not be available immediate applications. Region specific normal healthy animal profile is valuable in care planning elephants. The aim this study was to assess evolve the baseline reference...

The use of mixed venous oxygen saturation (SvO2) in patients with chronic congestive heart failure (CHF) has been advocated to analyze the action of therapy on cardiac index (CI). To evaluate the relationship between CI and SvO2, ten CHF patients (mean age 65 years) were studied before and one, two, three, four (T4), six, eight and 24 hours after oral administration of an angiotensin converting...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Cardiac rehabilitation program (CRP) is a multidisciplinary intervention tailored to improve functional fitness in different cardiovascular conditions. Patients with reduced left ventricular ejection fraction (LVEF) are commonly unrepresented hence the impact LVEF on uncertain. Purpose To evaluate changes capacity coh...

The hypothesis of an oxygen limited thermal tolerance due to restrictions in cardiovascular performance at extreme temperatures was tested in Atlantic cod, Gadus morhua (North Sea). Heart rate, changes in arterial and venous blood flow and venous oxygen tensions were determined during an acute temperature change to define pejus (= getting worse) temperatures which border the thermal optimum ran...

BACKGROUND: The present study was undertaken to examine the feasibility of venous oxygen measurements in the inferior vena cava (IVC) via a catheter through the umbilical vein. This may serve as a proxy for mixed venous oxygenation and the complications of right atrial cannulation can be avoided at the same time. It has the added advantage of not being affected by atrial right-left shunting. RE...

The umbilical artery and jugular venous blood gases of the first five neonatal puppies born from nine healthy bitches by elective caesarean section, were analyzed to determine whether the order of birth had any influence over the evaluated parameters. Anesthesia was induced with propofol (6.0 mg kg-1, IV) followed by epidural injection of 2% lidocaine chloride (5.0 mg kg-1). Additional boluses ...
