The Genotoxic and Cytotoxic Effects of Bisphenol-A (BPA) in MCF-7 Cell Line and Amniocytes.

Bisphenol-A (BPA) is an industrial xenoestrogen used widely in our living environment. Recently, several studies suggested that BPA has destructive effects on DNA and chromosomes in normal body cells via estrogen receptors (ER). Therefore, BPA could be considered as an important mediator in many diseases such as cancer.

A novel ABCB11 mutation in an Iranian girl with progressive familial intrahepatic cholestasis.

Progressive familial intrahepatic cholestasis is an autosomal recessive liver disorder caused by (biallelic) mutations in the ATP8B1 of ABCB11 gene. A nine-year-old girl with cholestasis was referred for genetic counseling. She had a family history of cholestasis in two previous expired siblings.

Isolation, characterization, and mesodermic differentiation of stem cells from adipose tissue of camel (Camelus dromedarius).

Adipose-derived stem cells are an attractive alternative as a source of stem cells that can easily be extracted from adipose tissue. Isolation, characterization, and multi-lineage differentiation of adipose-derived stem cells have been described for human and a number of other species. Here we aimed to isolate and characterize camel adipose-derived stromal cell frequency and growth characteristics and assess their adipogenic, osteogenic, and chondrogenic differentiation potential.

Chromosome abnormality rate among Iranian patients with idiopathic mental retardation from consanguineous marriages.

Introduction: Mental retardation (MR) has heterogeneous aetiology mostly with genetic causes. Chromosomal aberrations are one of the most common causes of MR. Reports on chromosome abnormality rate among consanguineous families are sparse.

Early spontaneous immortalization and loss of plasticity of rabbit bone marrow mesenchymal stem cells.

Objectives: Bone marrow-derived mesenchymal stem cells (BM-MSC) have been widely used for cell therapy and tissue engineering purposes. However, there are still controversies concerning safety of application of these cells after in vitro expansion. Therefore, we aimed to investigate the characteristics of rabbit BM-MSC during long-term culture.

Dormant phase and multinuclear cells: two key phenomena in early culture of murine bone marrow mesenchymal stem cells.

Special features of mesenchymal stem cells (MSCs) have made them a popular tool in cell therapy and tissue engineering. Although mouse animal models and murine MSCs are common tools in this field, our understanding of the effect of in vitro expansion on the behavior of these cells is poor and controversial. In addition, in comparison to human, isolation of MSCs from mouse has been reported to be more difficult and some unexplained features such as heterogeneity and slow growth rate in the culture of these cells have been observed.

M-banding characterization of a 16p11.2p13.1 tandem duplication in a child with autism, neurodevelopmental delay and dysmorphism.

We describe a partial duplication of the chromosome 16 short arm [46,XY,dup(16)(p11.2p13.1)] in an Iranian girl with autism, neurodevelopmental delay, mental retardation, very poor memory, and dysmorphism including sparse hair, upslanting palpebral fissures, long philtrum, micrognathia, hypotonia, small feet and hands, syndactyly of the fingers, and hypoplastic thumbs.
