OBJECTIVE: To discuss the use of alternative treatment methods in hemolytic disease of newborn to replace common early exchange transfusion. METHODS: Case report of newborn with intensive Rh incompatibility treated with intensive phototherapy, plus phenobarbital instead of traditional early exchange transfusion.RESULTS: The neonatés cord blood showed 9.2 mg/dL of total bilirubin and 39% hematoc...

The aim of this study was to evaluate mixed red cells population and red blood cell chimerism after hematopoietic stem cell transplantation. Red blood cell chimerism after hematopoietic stem cell transplantation was analyzed using a series of fluorescein isothiocyanate-conjugated monoclonal antibodies (BioAtlantic, France) directed against ABH, Rh (D, C, E, c, e), Kell, Duffy, Kidd, and Ss anti...

The association of deafness with haemolytic disease of the newborn has been reported by several authors in the past few years. Goodhill (1950) attempted a follow-up of 46 cases of haemolytic disease of the newborn. Of the 15 cases he managed to trace, two showed a significant degree of perceptive deafness. In a further investigation he obtained birth histories from the mothers of 904 severely d...

Cyto-nuclear incompatibility, a specific form of Dobzhansky-Muller incompatibility caused by incompatible alleles between mitochondrial and nuclear genomes, has been suggested to play a critical role during speciation. Several features of the mitochondrial genome (mtDNA), including high mutation rate, dynamic genomic structure, and uniparental inheritance, make mtDNA more likely to accumulate m...

Wolbachia pipientis is a bacterium that induces cytoplasmic incompatibility (CI), the phenomenon in which infected males are reproductively incompatible with uninfected females. CI spreads in a population of hosts because it reduces the fitness of uninfected females relative to infected females. CI encompasses two steps: modification (mod) of sperm of infected males and rescuing (resc) of these...

Nuclear-mitochondrial conflict (cytonuclear incompatibility) is a specific form of Dobzhansky-Muller incompatibility previously shown to cause reproductive isolation in two yeast species. Here, we identified two new incompatible genes, MRS1 and AIM22, through a systematic study of F2 hybrid sterility caused by cytonuclear incompatibility in three closely related Saccharomyces species (S. cerevi...

By introgressing Neurospora crassa translocations into N. tetrasperma, we constructed heterokaryons bearing haploid nuclei of opposite mating types, and either the translocation and normal sequence chromosomes (i.e., [T + N]) or a duplication and its complementary deficiency (i.e., [Dp + Df]). The [T + N] heterokaryons result from alternate segregation of homologous centromeres, whereas adjacen...

The Dobzhansky–Muller model posits that incompatibilities between alleles at different loci 5 cause speciation. However, it is known that if the alleles involved in a Dobzhansky–Muller 6 incompatibility (DMI) between two loci are neutral, the resulting reproductive isolation cannot 7 be maintained in the presence of either mutation or gene flow. Here we propose that speciation 8 can emerge thro...

To find markers linked to vegetative incompatibility (vic) genes in the chestnut blight fungus, Cryphonectria parasitica, we constructed a preliminary linkage map. In general, this map is characterized by low levels of polymorphism, as evident from the more than 24 linkage groups observed, compared to seven expected from electrophoretic karyotyping. Nonetheless, we found markers closely linked ...

Wolbachia are a group of maternally transmitted obligatory intracellular alpha-proteobacteria that infect a wide range of arthropod and nematode species. Wolbachia infection in Drosophila in most cases is associated with the induction of cytoplasmic incompatibility (CI), manifested as embryonic lethality of offspring in a cross between infected males and uninfected females. While the molecular ...
