The aortic isthmus (AoI) is a unique fetal watershed with a waveform reflecting its complex haemodynamic physiology. The systolic component represents left and right ventricular systolic ejection, and the diastolic component represents comparative downstream vascular impedance between the brachiocephalic and subdiaphragmatic fetal circulations. Several indices have been devised to quantify diff...

DOI: 10.5812/atr.7245 Implication for health policy/practice/research/medical education: The role of trauma in the modern society has a vital importance and significance role that resorting to any facilities and strategies to handle the dilemma seems worthful for all researchers in this s...

Severe sepsis has a high fatality rate, but no clinical indices for prognosis have been established. In recent years, the renin-angiotensin system (RAS) has received considerable attention. However, clinical data on RAS are inconsistent. Therefore, the aim of the present study was to assess the significance of RAS in the prognosis of sepsis. Blood samples were collected from patients, who met t...

We aimed to establish gestation age specific reference intervals for Doppler indices of fetal cardiac function from 12 to 40 weeks of pregnancy. In a cross-sectional observational study of singleton pregnancies, examinations were performed in 221 women evenly distributed across each week of pregnancy. Blood flow through the four cardiac valves was examined with Doppler. For the atrioventricular...

Most birds rely on flight for survival. Yet as an energetically taxing and physiologically integrative process, flight has many repercussions. Studying pigeons (Columba livia) and employing physiological and immunological indices that are relevant to ecologists working with wild birds, we determined what, if any, acute immune-like responses result from bouts of intense, non-migratory flight. We...

Background: Longevity of basic medical sciences is a major concern of medical educators and physicians. It has been shown that different learning styles can affect the half-life of the material. This study aimed to evaluate the effect of partially tests during renal physiology course on "the student’s retention of renal physiology knowledge" and "knowledge loss" in pharmacy and medical students...
