Objective(s): Bone marrow mesenchymal stem cells (MSCs) play an important role in bone health. Cadmium causes osteoporosis, but the exact mechanisms of its effect on MSCs are not known. Materials and Methods: Rats were treated with cadmium chloride (40 mg/l) in drinking water for six weeks, and then the biochemical and morphological studies on MSCs were carried out as a cellular backup for oste...

In his article “The Rise and Fall of the South African Bomb,” Peter Liberman uses organizational politics theory to explain South Africa’s latent development of a nuclear weapons program before 1977.1 He cites post-1976 security threats (from the Soviet Union and Cuba) as triggers for the militarization of the nuclear program and the building of six bombs. Although Liberman is less clear about ...

Objective(s):In previous investigations, we have shown para-nonylphenol (p-NP) caused significant reduction of proliferation and differentiation of rat bone marrow mesenchymal stem cells (MSCs) in vitro. In this study, we first treat the rats with p-NP, then carried out the biochemical and morphological studies on MSCs. Materials and Methods: Proliferation property of cells was evaluated with t...

Increasing attention has been focused in recent years on the need for multilateral negotiation processes in the disarmament and arms control field to “think outside the box” in addressing contemporary challenges. But beyond recognition that there are imperfections in current approaches, it is not always clear that the parameters of the existing box are sufficiently understood or, indeed, what t...
