A HIGH INCIDENCE OF MEIOTIC SILENCING OF UNSYNAPSED CHROMATIN IS NOT ASSOCIATED WITH SUBSTANTIAL PACHYTENE LOSS IN HETEROZYGOUS MALE MICE CARRYING MULTIPLE SIMPLE ROBERTSONIAN TRANSLOCATIONS.

A high incidence of meiotic silencing of unsynapsed chromatin is not associated with substantial pachytene loss in heterozygous male mice carrying multiple simple robertsonian translocations.

Meiosis is a complex type of cell division that involves homologous chromosome pairing, synapsis, recombination, and segregation.When any of these processes is altered, cellular checkpoints arrest meiosis progression and induce cell elimination.Meiotic impairment is particularly frequent in organisms bearing chromosomal translocations.When chromoso

Intelligent Hybrid Taguchi-Genetic Algorithm for Multi-Criteria Optimization of Shaft Alignment in Marine Vessels

An intelligent hybrid Taguchi-genetic algorithm (IHTGA) is used to optimize bearing offsets and shaft alignment in a marine vessel propulsion system.The objectives are to minimize normal shaft stress and shear force.The constraints are permissible reaction force, bearing stress, shear force, and bending moment in the shaft thrust flange under cold

Transspecies Transmission of Gammaretroviruses and the Origin of the Gibbon Ape Leukaemia Virus (GaLV) and the Koala Retrovirus (KoRV)

Transspecies transmission of retroviruses is a frequent event, and the human immunodeficiency virus-1 (HIV-1) is a well-known example.The gibbon ape leukaemia virus (GaLV) and koala retrovirus (KoRV), two gammaretroviruses, are also the result of a transspecies transmission, however from a still unknown host.Related retroviruses have been found in
