Geomorphic status of regulated rivers in the Iberian Peninsula.

River regulation by dams modifies flow regimes, interrupts the transfer of sediment through channel networks, and alters downstream bed dynamics, altogether affecting channel form and processes. So far, most studies on the geomorphic impacts of dams are restricted to single rivers, or even single river stretches. In this paper we analyse the geomorphic status of 74 river sites distributed across four large basins in the Iberian Peninsula (i.

[The Alliance for the Prevention of Colorectal Cancer in Spain. A civil commitment to society].

Colorectal cancer (CRC) is the most common malignant tumor in Spain, when men and women are considered together, and the second leading cause of cancer death. Every week in Spain over 500 cases of CRC are diagnosed, and nearly 260 people die from the disease. Epidemiologic estimations for the coming years show a significant increase in the number of annual cases.

[Rh (D) alloimmunization and pregnancy. Analysis of the causes after prophylaxis introduction].

Purpose: Prenatal and postnatal prophylaxis of the Rh (D) haemolytic disease of the newborn have clearly reduced the number of cases but still there are alloimmunizations.

Patients And Methods: All cases detected in our Hospital in the last 24 years have been reviewed and possible causes analyzed.

Results: From a total of 10,332 deliveries in Rh (D) negative women we have detected 114 anti-D in 86 women.
