    Notes: [Auszug] All the culture techniques used 95% oxygen and 5% CO2 at 1 atm but New5 has shown that hyperbaric oxygen, at 2 to 3 atm, permits prolonged survival of twenty-five somite rat embryos in static culture medium and forty somite rat embryos in circulating medium. The inference was that hyperbaric oxygen ...

    Notes: [Auszug] Hearts were cut vertically into two along the atrial and ventricular septa and cultured with the cut surfaces touching in as nearly normal position as possible. They were put on stainless steel wire mesh?bridge-shaped grids?with a mesh size of 0.1 mm, and were arranged so that the lower surfaces of ...

    Notes: [Auszug] Occasional cerebral complications during cardiac surgery seem to be caused by gas embolism. Evidence is presented here for the existence of regions of sub-atmospheric pressure in the external circulation—particularly in the roller pump—as a result of which bubbles of gas form in the ...

    Notes: [Auszug] Wildenthal described a method in which functioning foetal mouse hearts could be studied in vitro for prolonged periods1,2. We have repeated Wildenthal's experiments and obtained comparable results. We tried other techniques for maintaining the hearts, including aortic perfusion with scaled-down ...

    Notes: [Auszug] We wished to study the biological effects of implants of foetal heart, or extracts, in damaged areas of the heart. We were particularly interested in the first 20-30% of term when most human abortion material would be available. In the species we studied, we found that there was a direct ...

    Notes: Abstract Magnetic resonance phase-shift-induced velocity mapping is a powerful technique for measuring in vivo blood velocity and flow non-invasively. Using this method we examined dimensions, distensibility, blood flow and its regional distribution in the abdominal aorta in 10 normal volunteers. Data were acquired at three levels of the descending aorta. Thirty percent reduction in diastolic cross sectional area was observed in the caudal direction between these levels. Total blood flow (ml/min) in the abdominal aorta at the three sites was 4094 ± 1600, 2339 ± 910 and 1602 ± 549 respectively. Flows in the coeliac trunk, superior mesenteric artery and renal arteries were also calculated. The net flow in the abdominal aorta above the coeliac trunk was persistently forward, while there was considerable backflow (13% of total instantaneous flow) below the renal arteries during early diastole. Magnetic resonance imaging is a non-invasive technique for quantitative assessment of blood flow in the abdominal aorta and its main branches.

    Notes: Conclusions Functional evaluation of the cardiovascular system using rapid imaging (spiral echo planar), chemical shift, and velocity mapping is capable of making the diagnosis in congenital and acquired cardiovascular disease which, between them, cause the largest number of deaths of any disease in the western world and massive morbidity and suffering. Furthermore, for the first time in the history of medicine, there is the opportunity to apply preventive measures to eardicate the epidemic of preventable arterial disease. There needs to be a change of emphasis and a switching of resources to apply to the most common diseases rather than to those which are most easily studied. There also needs to be proper training in cardiovascular MR, not so much for imagers as for cardiologists and experts in vascular disease.
