Primary clear cell adenocarcinomas most commonly involve the genitourinary system, including the vagina. Previously, primary clear cell adenocarcinomas of the vagina have been discussed within the context of prenatal exposure to diethylstilbestrol. Due to its widely proven role in the development of this carcinoma, administration of diethylstilbestrol is prohibited. We present two cases of non-...

background: alpha particle irradiation from radon progeny is one of the major natural sources of effective dose in the public population. oncogenic transformation is a biological effectiveness of radon progeny alpha particle hits. the biological effects which has caused by exposure to radon, were the main result of a complex series of physical, chemical, biological and physiological interaction...

Two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. Cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HepG2 (liver hepatocellular cells), A549 (adenocarcinomic human alveolar basal epithel...

Assessment of the cellular effects of natural and/or synthetic products is one of the major goals in biological experiments. This assessment may be conducted at different levels; cellular viability, cellular biological activity, and cellular structure and morphology. Different assays are available for any of above purposes. It is becoming of a routine exercise to apply any of these assays, and ...

Basic IC fabrication techniques are employed in this paper with the purpose of designing a microfluidic device with a 3D electrode arrangement to separate live and dead biological cells. This is done using the concept of dielectrophoresis, which describes the transnational motion of particles due to the application of a non-uniform electrical field. The simulations where carried out using the p...

The cell biological basis of endometrial receptivity and trophoblast invasiveness, the two preconditions for implantation ("implantation windowtl), still remains enigmatic. Recently, however, the application of modern concepts of cell biology and developmental biology concentrating on celladhesion and cell polarity seems to open promising new views of these phenomena. At implantation initiation...
