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...

Human Rhnu11 red blood cells fail to react with Rh antibodies, indicating that these cells are either devoid of Rh protein or, like other species, possess antigenically distinct variants. To determine whether Rhnull cells possess an Rh-like polypeptide, 32-kDa proteins from D--, rr, and Rhnull cells were labeled with the cysteine-specific probe, lZ61-labeled pyridyldithioethylamine. Size compar...

The visual photopigment rhodopsin (Rh) is a prototypical G protein-coupled receptor (GPCR) responsible for initiation of the phototransduction cascade in rod photoreceptors. Similar to other GPCRs, Rh can form dimers or even higher oligomers and tends to have a supramolecular organization that is likely important in the dim light response. Rh also exhibits high affinity for lipid rafts (i.e. ra...

  Toxoplasma gondii contain various immunogenic antigens. The most important Toxoplasma antigens are somatic and excreted/secreted antigens. Rhoptry proteins are known as excreted/secreted antigens. These antigens have been proposed as a vaccine candidate against toxoplasmosis. The main objective of the present work was cloning rhoptry protein1 (ROP1) Gene of Toxoplasma gondii (RH) in a cloning...

BACKGROUND A woman's candidacy for Rh immune globulin depends on whether her blood type is Rh-positive (D antigen-positive) or Rh-negative (D antigen-negative). New molecular blood-typing methods have identified variant D antigens, which may be reported as Rh-positive or Rh-negative depending on the laboratory method. We describe a case illustrating the effect of the new laboratory methods on a...

Rh(D) antigen-containing polypeptide was prepared by immune precipitation of intact cDE/cDE erythrocytes by using a high-titer preparation of polyclonal anti-D. when isolated Rh(D) polypeptide was administered to rabbits, antibody was produced that was unresponsive toward Rh-positive and -negative cells but reacted strongly with the immunogen in enzyme-linked immunosorbent assay-type immunobind...

Recently human interleukin-3 (IL-3) produced by molecular cloning was characterized as a growth factor for basophils and eosinophils in human bone marrow cultures. Since we found a similar activity of the human factor on simian bone marrow cells, we investigated the in vivo effects of recombinant human (rh) IL-3 in healthy rhesus monkeys (n = 10). rh IL-3 was administered subcutaneously (SC) to...
