  • The successful introduction of extracellular gadolinium-based contrast agents for contrastenhanced MR angiography, and their wide acceptance today, raise the question of what part an intravascular contrast agent might play in diagnostic imaging. The answer lies in the capacity of an intravascular agent to give us high-level diagnostic information from first pass arterial imaging and, at the same time, to yield additional diagnostic value by allowing delayed imaging from the same contrast injection.

  • Computed tomography (CT) is the mainstay of cancer imaging outside of the central nervous system. Advances in multidetector CT (MDCT) technology have had a profound impact on its diagnostic capabilities. Such techniques as multiphase, single breath-hold imaging, CT angiography (CTA), volume rendering and virtual colonography owe their success to the development of multidetector arrays with continuously moving gantries.

  • The Institutional System of Protection (ISP), established by Decree-law 6/2010 offers an effective instrument to bring together a group of credit entities in order to pool their risk management strategies and develop risk sharing strategies. In the special case of saving banks, this system is organised around a central entity in the form of a commercial bank which will pool their risk management strategies, risk sharing and will have full access to financial markets, including raising capital. Thus, the ISP increases the ability to access markets in order to obtain equity.

  • Conventional treatments of hemorrhagic cystitis are hyper-hydration, diuresis and bladder irrigation to wash out viral particles and clots, and to prevent retrograde infection to kidneys and post-renal failure due to urethral obstruction caused by clots. High titer γ- globulin to specific adenovirus serotype is also administrated. In particular, serotype 35 specific antibody was present only at a very low titer in pooled gamma globulin (Flomenberg et al., 1987).

  • All of the cell types in the peripheral blood and some cells in every tissue of the body are derived from hematopoietic (hemo: blood; poiesis: creation) stem cells. If the hematopoietic stem cell is damaged and can no longer function (e.g., due to the nuclear accident at Chernobyl), a person would survive 2–4 weeks in the absence of extraordinary support measures. With the clinical use of hematopoietic stem cells, tens of thousands of lives are saved each year (Chap. 108). Stem cells produce tens of billions of blood cells daily from a stem cell pool that is estimated to be...

  • Theoretically, use of autologous HS could eliminate the risks of disease transmissions and immune reactions. However, it is not always possible to obtain a sufficient amount of autologous HS for ex vivo expansion of BMSCs. In fact, over 400 mL of peripheral blood is usually required to obtain 200 mL of autologous HS, which is only sufficient to support the growth of BMSCs for a few passages. Therefore, collection of a sufficient amount of autologous HS is a considerable burden for anaemic patients as well as for healthy female patients with a low body weight.

  • Internal iron exchange. Normally about 80% of iron passing through the plasma transferrin pool is recycled from broken-down red cells. Absorption of about 1 mg/d is required from the diet in men, 1.4 mg/d in women to maintain homeostasis. As long as transferrin saturation is maintained between 20–60% and erythropoiesis is not increased, iron stores are not required. However, in the event of blood loss, dietary iron deficiency, or inadequate iron absorption, up to 40 mg/d of iron can be mobilized from stores. RE, reticuloendothelial.

  • Apheresis technology is used for the collection of multiple units of platelets from a single donor. These single-donor apheresis platelets (SDAP) contain the equivalent of at least six units of RD platelets and have fewer contaminating leukocytes than pooled RD platelets. Plasma may also be collected by apheresis. Plasma derivatives such as albumin, intravenous immunoglobulin, antithrombin, and coagulation factor concentrates are prepared from pooled plasma from many donors and are treated to eliminate infectious agents.
