HEMODYNAMICS STUDIES OF THE PREOVULATORY FOLLICLE AND CORPUS LUTEUM IN CATTLE
… follicle and corpus luteum hemodynamics by color-Doppler ultrasonography is becoming more commonly used in cattle reproductive management. Improved understanding of the relationships between size and blood flow of the preovulatory follicle (POF) and corpus luteum (CL) with the subsequent systemic …

The impact of ischaemic preconditioning on cerebrovascular function in healthy individuals.
… of 10 mmHg. CBF was measured using transcranial Doppler ultrasonography. Cerebral autoregulation was assessed using the squat to stand technique (5 second squat-5 second stand) while cerebral CO2 reactivity was assessed via a period of hypercapnia involving inhalation of 5% CO2. Finally, cerebral …

Stellenwert der Messung des renalen Widerstandsindex bei Patienten mit Leberzirrhose
… The extent of resistive index detected with doppler ultrasonography corresponds with the risk of developing a hepatorenal syndrome. This study examines in daily routine work if the resistive index is influenced by therapy of blood pressure or diuretics. The study discusses the value of …

Audit of the quality and cost of acute inpatient stroke care in the general medical wards at Groote Schuur Hospital
… was performed on 95% of patients, carotid duplex Doppler ultrasonography and echocardiography were not often done. Although all patients with ischaemic stroke received inpatient antiplatelet or anti - coagulation therapy, not all risk factors were adequately addressed on discharge. The median cost …
