Various studies support the view that analogs of luteinizing hormone-releasing hormone (LH-RH) exert some direct effects on mammary tumor cells. Recently, new LH-RH antagonists [Ac-D-Nal(2)1,D-Phe(pCl)2,D-Trp3,D-Hci6,D-Ala10]-LH-RH (SB-29) and [Ac-D-Nal(2)1,D-Phe(pCl)2,D-Trp3,D-Cit6,D-Ala10]LH-RH (SB-30), which are devoid of edematogenic effects, were synthesized. In this study, we examined whe...

OBJECTIVE To determine the frequency of ABO blood group and Rhesus (Rh) D antigen in the females of "District" Peshawar, Khyber Pakhtunkhwa Province, Pakistan. METHODS This cross-sectional study was conducted on 429 women having pregnancy induced hypertension, admitted in the three teaching hospitals of Peshawar, over a period of one year. Blood sample was collected from each subject after ta...

Human red blood cells are traditionally typed as Rhesus (Rh)-positive or -negative depending on the presence or absence of the Rh D antigen. A recent report demonstrated that the Rh D gene is completely absent in Rh D-negative individuals. In this study, Rh D-negative blood donors with ccee (n = 25) and CCee (n = 3) phenotypes were examined for the presence of absence of the D gene. Polymerase ...

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...

background: rh (rhesus) is a highly complex blood group system in man deeply rooted in transfusion medicine. isolation of rhd from cord blod, cloning and expression of recombinant rhd antigen in bacterial expression system was the aim of this study. methods: total rnas were extracted from cord blood (o + ).  the quality of rna was determined by electrophoresis. in or­der to obtain coding sequen...

The minimum number of IgG anti-A (or anti-B) molecules detectable on A or B red cells by the antiglobulin reaction was found to be the same-that is, about 150 molecules per red cell-with newborn as with adult cells. Furthermore, the ratio of anti-IgG bound to IgG anti-A (or anti-B) molecules was the same whether the anti-A (or anti-B) molecules were present on newborn or on adult cells and was ...

Reports of heterogeneity of IgG receptor activity of normal circulating neutrophils prompted measurements in myeloproliferative disease to determine if dysplasia of the hematic stem cell resulted in an abnormality of this membrane property. IgG receptors were assayed by rosette formation in suspension with human Rh-positive erythrocytes sensitized with high-titer Rh antiserum. IgG receptors wer...

The effect of ractopamine hydrochloride (RH) and zilpaterol hydrochloride (ZH) on slice shear force (SSF) and sensory characteristics of beef from calf-fed Holstein steers was evaluated. All steers were implanted with a progesterone (100 mg) plus estradiol benzoate (10 mg) implant followed by a terminal trenbolone acetate (200 mg) plus estradiol (40 mg) implant. Steers were blocked by weight in...
