background: selecting the best embryo for transfer, with the highest chance of achieving a vital pregnancy, is a major goal in current in vitro fertilization (ivf) technology. the high rate of embryonic developmental arrest during ivf treatment is one of the limitations in achieving this goal. chromosomal abnormalities are possibly linked with chromosomal arrest and selection against abnormal f...

Background: Tuberculosis of the genital tract is one of the major causes of gynecological morbidity. Genital TB affects about 12% of patients with pulmonary tuberculosis and represents 15-20% of extrapulmonary tuberculosis.

Despite being successfully used to produce live offspring in many species, somatic cell nuclear transfer (NT) has had a limited applicability due to very low (>1%) live birth rate because of a high incidence of pregnancy failure, which is mainly due to placental dysfunction. Since this may be due to abnormalities in the trophectoderm (TE) cell lineage, TE cells can be a model to understand the ...
