recombinant human erythropoietin (rh-epo) is known to accelerate erythropoiesis in preterm infants. the purpose of this study was to compare the effectiveness of early treatment with two doses of rh-epo (high vs. low dose) in the management of anemia of prematurity. twenty preterm infants with hematocrit (hct) < 30% when infant’s age was between 2 to 3 weeks after birth or hct <25% when infant’...

A new class of (E)-N-phenyl-3-styrylpyridin-2-amine conjugates were designed and synthesized on the basis of E7010 and resveratrol scaffolds. These conjugates were evaluated for their antiproliferative activity in four human cancer cell lines with GI50 values ranging from 2.1 μM to 20 μM. Two of the conjugates RSV-1 and RSV-11 were found to possess 13-fold higher GI50 values than resveratrol an...

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 ...

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...

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...

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...

Under favorable soil conditions such as existence of easily destructible organic compounds, balanced heat and moisture, adequate ventilation and abundant nutrients, organic materials are mineralized. Once mineralizing occurs, mineral elements like P, S, Ca, Mg, K and other cations are released. A related study was conducted to determine the effect of seven organic fertilizers (Leaf Mold (LM), R...
