Gene flow within populations can occur by sexual and/or parasexual means. Analyses of experimental and in silico work are presented relevant to possible gene flow within the aspergilli. First, the discovery of mating-type (MAT) genes within certain species of Aspergillus is described. The implications for self-fertility, sexuality in supposedly asexual species and possible uses as phylogenetic ...

The ability of genetic isolation to block gene flow plays a key role in the speciation of sexually reproducing organisms. This paper analyses the hybrid zone dynamics affected by"weak"Haldane's rule, namely the incomplete hybrids inferiority (sterility/inviability) against the heterogametic (XY or ZW) sex caused by a Dobzhansky-Muller incompatibility. Different strengths of incompatibility, dis...

Iso-leukoagglutinins are known to develop primarily in multitransfused patients (1-6). A possibly different kind of agglutinin for white cells, such as that related to aminopyrine leukopenia, has also been described (7). The therapeutic administration of blood and of aminopyrine may not be the only stimuli for leukoagglutinin production. Two groups of investigators, Dausset, Nenna and Brecy (8)...

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 ...

Polyhydramnios occurs in 1-2% of pregnancies and may be idiopathic in more than half of the cases. The diagnosis of idiopathic polyhydramnios can be made only in the absence of maternal diabetes, fetal anomalies, aneuploidies, multiple gestation, Rh incompatibility, placental tumours and non-immune hydrops. Rarely, idiopathic polyhydramnios may be recurrent in future pregnancies and sometimes n...

In the present work a new indomethacin (IND) self-nanoemulsifying drug delivery formulation (SNEDDF) have been prepared to enhance its dissolution which in turn could provide a better chance for IND oral absorption. IND SNEDDF have been prepared using different concentrations of castor oil as a solvent for IND, Cremophor RH 40 (Cr-40) as surfactant and Capmul MCM-C8 (Ca-8) as co-surfactant. Dro...

C3, factor B, and alpha-1-antitrypsin were determined in newborn infants with septicaemia and sclerema, associated with suspected infections, ABO or Rh incompatibility, and hyperbilirubinaemia of unknown origin, during and after treatment with exchange transfusion. Activation products from C3 and factor B, the clearance of the transfused C3, and its synthesis by the recipient were determined al...
