(5) Neonatal alloimmune thrombocytopenia (NAIT) is caused by platelet antigen incompatibility between the mother and fetus.
(6) Neonatal alloimmune thrombocytopenia (NAIT) occurs when maternal alloantibodies to antigens present on fetal platelets cause their immune destruction resulting in thrombocytopenia in the newborn infant or fetus.
(7) Neonatal alloimmune thrombocytopenia (NAIT) is due to fetomaternal incompatibility for platelet specific antigens, most frequently HPA-1a (PLA1) and HPA-5b (BRa).

(9) An immune response to human platelet antigens (HPA), as in neonatal alloimmune thrombocytopenia (NAIT) and post-transfusion purpura (PTP), is the exception rather than the rule and evidence is accumulating for the importance of human leucocyte antigen (HLA) class II restriction in this situation.
(10) This report of an unaffected pregnancy in a woman with a history of previous pregnancies complicated by NAIT illustrates the role of paternal and fetal platelet phenotyping in managing existing pregnancies at risk of NAIT.
(11) The sera of 219 Zwa-positive mothers who gave birth to children with clinically suspected neonatal alloimmune thrombocytopenia (NAIT) were tested for platelet-reactive antibodies using the platelet adhesion immunofluorescence test and a glycoprotein-specific immunoassay (MAIPA).
(12) Because there is high risk that subsequent pregnancies might be also affected by NAIT, the mothers of a previously affected child should be managed similarly to the HPA-1b mothers (PIA2, Zwb).
(13) Platelet specific alloantibodies cause neonatal alloimmune thrombocytopenia (NAIT), posttransfusion purpura (PTP) and may be found in patients who are refractory to HLA-matched platelet transfusion.
(14) In accordance with established criteria, the Sra antigen represents the first example of a "private" platelet alloantigen that bears significance in rare instances of NAIT.
(15) We report our experience with the serological diagnosis of 14 NAIT cases using new performing techniques such as western blotting (WB) and MAIPA (monoclonal antibody specific immobilization of platelet antigens).
(16) This is a report of 39 cases of NAIT involving the HPA-5b antigen.
(17) Bra antibodies were from mothers of children with neonatal alloimmune thrombocytopenia (NAIT), and anti-Brb was found in the serum of a polytransfused patient.
(18) NAIT is mainly due to alloimmunization; the frequency varying among ethnic groups.
(19) Immunization against these alloantigens is implicated in NAIT and poly-transfused patients.
(20) In the serum of a mother who gave birth to a child with the typical clinical picture of NAIT we found an antibody directed against the new platelet antigen Sra.
Nit
Definition:
(n.) The egg of a louse or other small insect.
Example Sentences:
(1) Okay, that number 8 ranking isn’t incredibly impressive but it’s much better than, say, settling for a NIT bid and then (hilariously) losing in the first round .
(2) The extent and duration of the blood pressure (BP) lowering effect of 20 mg nitrendipine (NIT) once daily and 40 mg nicardipine slow release (NIC) twice daily were compared in 12 men (aged 39-55 years) with mild essential hypertension according to a randomized, cross over study.
(3) nit-4 is a pathway-specific regulatory gene which controls nitrate assimilation in Neurospora crassa, and appears to mediate nitrate induction of nitrate and nitrite reductase.
(4) We have studied the fate of NIT in the immature female rat, the animal model in which most of the biochemical studies of NIT have been carried out.
(5) In Neurospora crassa, the expression of nit-3, the structural gene which encodes nitrate reductase, is highly regulated and requires both nitrate induction and nitrogen catabolite derepression.
(6) In cells that contain a mutation in the putative regulatory gene nit-2, significantly lower levels of the 3.4-kilobase transcript were found, indicating that the wild-type nit-2 gene is involved in the control of nitrate reductase transcript levels.
(7) Approximately 80% of the infested children had nits that were 2-5 cm away from the scalp.
(8) His children will get used to a father who wears pants, without a dagger, and who does not pick out their nits in public.
(9) The lack of inhibitory effect by Nit-arg in cultured islets may reflect the absence of endothelial or nervous cells in the cultured islets.
(10) The synthesis and turnover of the nit-3 mRNA were also examined and found to occur rapidly and efficiently under changing metabolic conditions.
(11) Aspergillus extracts contained an inhibitor(s) which was measured by the decrease in NADPH-dependent nitrate reductase formed when extracts of Rhodospirillum rubrum and N. crassa, nit-1 were incubated at room temperature.
(12) The presence of molybdenum cofactor in the nitrate reductase was indicated by the formation of molybdopterin form A in the oxidation of the enzyme by iodine and by the complementation of NADPH-nitrate reductase with the heart-treated enzyme in the extract of Neurospora crassa nit-1.
(13) The presence of multiple copies of wild-type or mutant nit-4 genes did not generally lead to increased enzyme activity or growth rate, but instead frequently appeared to be detrimental to nit-4 function.
(14) Mutants of the nit-2 locus, a regulatory gene which is postulated to mediate nitrogen catabolite repression, are deficient in the ability to utilize several amino acids as well as other nitrogen sources used by wild type.
(15) An average of ten nits were taken from each patient both before and after treatment.
(16) So there are nits to pick but, by getting specific, Labour puts the coalition on the back foot.
(17) Nucleotide sequencing has revealed that the three nit-4 mutants, alleles 15, 1214, and 2994, are the result of a missense mutation, a nonsense mutation and a frameshift mutation, respectively.
(18) In addition, Nit may induce anti-anxiety through the modulation of Ca2+ mobilization in the central nervous system.
(19) Nit-picking about the detailed mechanisms of governance and accountability.
(20) However, transformants obtained with most of these nit-4 mutant genes possess a markedly reduced level of nitrate reductase and grow only slowly on nitrate, emphasizing the need to examine quantitatively the affects of in vitro-manipulated genes.
