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...

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...

Background: Despite the meager role of the masculine agent in infertility (the low number of infertile men than women infertile), there are men whose wives are unable to become pregnant due to the absence of sperm, decreased numbers of sperm or lack of sufficient motile sperm. Utilizing donated sperm is a method that enables these families to have children. The use of this method prompts us to ...

background: several influential factors such as transcription factors and intracellular signaling components are involved in differentiation of stem cells into a specific lineage. p15 and p16 proteins are among these factors. accumulating evidences has introduced the epigenetic as a master regulator of these factors during lineage specification. the main objective of this study is to determine ...

We have examined mitochondrial DNA (mtDNA) restriction-site variation within and between populations of fall-adult field crickets across a narrow hybrid zone in Connecticut. Our analysis reveals two distinct mtDNA lineages, each consisting of a single common genotype together with one or more rare genotypes. Outside the hybrid zone, the association between mtDNA genotype and species designation...

Derma is progenitor cells sours, which are able to differentiate further in several mesodermal lineage and neural and endodermal lineage. Culture conditions, skin taking site and culture medium composition considerably contribute to it. Spheroid cultured mesenchymal dermal cells contribution to skin regeneration in granulating wound in rat model was estimated.
