The past few years have seen considerable advances in speciation research, but whether drift or adaptation is more likely to lead to genetic incompatibilities remains unknown. Some of the answers will probably come from not only studying incompatibilities between well-established species, but also from investigating incipient speciation events, to learn more about speciation as an evolutionary ...

Speciation often results from the accumulation of "complementary genes," i.e., from genes that, while having no deleterious effect within species, cause inviability or sterility when brought together with genes from another species. Here I model speciation as the accumulation of genic incompatibilities between diverging populations. Several results are obtained. First, and most important, the n...

methods this prospective observational study was conducted in a tertiary level neonatal intensive care unit, princess esra hospital, deccan college of medical sciences, hyderabad, telangana, india. consecutive intramural and extramural neonates admitted to neonatal intensive care unit with the rh-negative mother’s blood group and hyperbilirubinemia were enrolled. neonates born to rh+ve mothers ...

introduction hydrops fetalis is a serious condition in fetal period, characterized by the presence of serous fluid accumulation in at least two potential spaces in fetus including pleural effusion, pericardial effusion, and ascites. the incidence of hydrops fetalis is one per 2500-3000 pregnancies. this condition is followed by different diseases. fetal hemolytic anemia and its hypoxemia due to...

An inexpensive and simple technique for assessing fetomaternal bleeds in cases of Rh(D) incompatibility is described. The method is unlikely to replace the acid elution technique, but it may be of use in cases where results are in doubt owing to the presence of F cells of maternal origin.

Total number of abortions: 30,699.  60% of abortions were criminal and the re- mainder were due to:  (a)Cervical incompetence  (b) hypothyr oidism (c) Listeriosis (d) Toxoplasmosis (e) Luteal phase deficiency (f) Placental deficiency Mg) Rh and ABO incompatibility and unknown etiology.  Therapeutic abortions were also performed in several cases due to:  (a) Miliary tube...

Abstract Background Parental blood variables are one of the most important medical-biological causes of intellectual and physical-movement disabilities. The purpose of this study was to identify the relationship between parents’ blood variables (ABO and Rh blood type) and their relationship with frequency of intellectual and physical-movement disabilities in Isfahan province. Materials...

BACKGROUND Neonatal jaundice that occurs in ABO or Rhesus issoimunisation has been recognized as one of the major risk factors for development of severe hyperbilirubinemia and bilirubin neurotoxicity. AIM Aim of our study was to investigate clinical and laboratory parameters associated with hemolytic jaundice due to Rh and ABO incompatibility and compare results with the group of unspecific j...
