Background: This paper presents a method to reduce radiation exposure during mammography by analysing the doses to ipsilateral and contralateral breasts and to adjacent organs by evaluating material-dependent shielding performance.  Materials and Methods: Six target-filter combinations (Mo-Mo, Mo-Rh, Rh-Rh, Rh-Mo, W-Mo, W-Rh) were tested by measuring the doses delivered to the breasts and adjac...

background one of the most important cause of severe neonatal hyperbilirubinemia is hemolysis including rh incompatibility.  the aim of this study was to assess the rate of hyperbilirubinemia due to hemolysis in rh positive neonates  born to rh negative mothers. methods in this retrospective study from march 1998 to february 2003, 60 icteric rh positive newborns that were born to rh negative mo...

The expression ' typing of blood' has been applied loosely to determination of blood groups. It should not be so applied. One groups blood in determining 0, A, B and AB; types blood in determining M, N and MN; Rhesus groups blood in determining the Rh -fand Rh states; and Rhesus types (or Rh types) blood in determining R-h0, Rh', Rh", Rh'Rh", Rh15 Rh2, RhjRh2, and rh (using C-D-E system for a p...

Reticulohistiocytoma (RH) is a dermal histiocytic infiltration composed of large histiocytes with eosinophilic glassy cytoplasm. RH is classified into three clinical forms: solitary RH, diffuse cutaneous RH without systemic involvement and multicentric reticulohistiocytosis with systemic diseases. Solitary RH generally manifests as a nodular lesion in adults without accompanying systemic diseas...

The title compound, trans-[RhCl(C(18)H(14)BrP)(2)(CO)], has a slightly disordered square-planar geometry with the Rh ion(I) situated on an inversion the centre and carbon-yl-chloride disorder observed as a result of the crystallographic inversion symmetry. Selected geometric parameters include: Rh-P = 2.3430 (8) Å, Rh-Cl = 2.434 (3) Å, Rh-C = 1.722 (8) Å, P-Rh-P = 180.00 (3)°, P-Rh-Cl = 95.40 (...

Nothing in the immunological constitution of human red blood cells has grown so luxuriantly such a short time as the details of the Rh antigens (Rh 'factor', a haemagglutinogen, an antigen contained in the red blood cells). Six years ago there was one antigen, Rh, and two characters, (i) Rh positive, Rh, dominant and (w) Rh negative, rh, recessive. To-day there are three antigens and eight type...

The incidence of maternal Rh immunization in Rh-negative women following a single ABO compatible Rh-positive pregnancy is about 17%. This incidence was determined by following Rh-negative women through two Rh-incompatible pregnancies and analysing their sera for anti-Rh at the time of delivery of their second observed pregnancy. Maternal Rh immunization occurs almost exclusively after delivery;...

I describe and discuss the sometimes heated controversy surrounding the recognition heuristic (RH) as a model of inferential decision making. After briefly recapitulating the history of the RH up to its current version, I critically evaluate several specific assumptions and predictions of the RH and its surrounding framework: recognition as a memory-based process; the RH as a cognitive process ...

Rhesus (Rh) proteins were first identified in human erythroid cells and recently in other tissues. Like ammonia transporter (Amt) proteins, their only homologues, Rh proteins have the 12 transmembrane-spanning segments characteristic of transporters. Many think Rh and Amt proteins transport the same substrate, NH(3)/NH(4)(+), whereas others think that Rh proteins transport CO(2) and Amt protein...
