lineage in the islamic law is one of the most basic human rights each individual inherits from his family. when modern assisted reproductive technologies appeared in recent decades, the issue of lineage and the child’s rights did not encounter serious challenges. but with the advent of these technologies, the issue of the child’s lineage resulting from new technologies has become the center of ...

Although symmetry may be important for understanding the selection of form in art over the historical period, this preference may have originally stemmed from certain basic perceptual mechanism that initially arose during prehistory. The first signs of an awareness to symmetry can be found in the archaeological record with the arrival of Acheulean handaxes, especially those dating from 500,000 ...

BACKGROUND Menstrual blood-derived stem cells (MenSCs) are a novel source of stem cells that can be easily isolated non-invasively from female volunteered donor without ethical consideration. These mesenchymal-like stem cells have high rate of proliferation and possess multi lineage differentiation potency. This study was undertaken to isolate the MenSCs and assess their potential in differenti...

F etal cells are consistently found in the maternal circulation, and polymerase chain reaction based studies have led to the identification of cell free fetal DNA (fetal DNA) in maternal blood. Approximately 1.2 nucleated fetal cells/ml of whole blood from women carrying a male fetus were detectable, and relative enrichment of fetal DNA was detected in the maternal plasma and serum. The amount ...

Differentiation is an epigenetic process which is installed by changes of transcriptional programs over successive cellular divisions. A number of studies have reported the effects of biochemical modifications of chromatin (DNA and chromatin proteins) on the regulation of transcription. Although, these studies are able to explain how transcription of a given gene is regulated (toward activation...

SUMMARY Genomic imprinting and X chromosome inactivation (XCI) require epigenetic mechanisms to direct allele-specific expression. Despite their critical roles in embryonic development, how universal regulators coordinate these specific tasks from single locus chromosome-scale remains understudied. Here, we systematically disrupted multiple essential pathways within polymorphic F1 zygo...

Genetic parameters for nuclear and cytoplasmic genetic effects were estimated from preweaning growth data collected on three synthetic lines of beef cattle differing in mature size. Lines of small-, medium-, and large-framed calves were represented in each of two research herds (Rhodes and McNay). Variance components were estimated separately by herd and size line for birth weight and 205-d wei...
