Cytogenetic aspects of neutron -induced cellular response

Effect of Chromium on Certain Aspects of Cellular Toxicity

Introduction: The impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male Wistar rats (80-100 g body weight). Material & Method: It was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight a...

Selected Aspects of Neutron Decay

Precision measurements of neutron decay offer complementary access to particle physics at small distance scales or high energies. In particular they allow tests of the V-A structure of the weak interaction. Among many experimental activities which are ongoing around the world we present two new experiments which are planned or studied for the near future. While the neutron lifetime still bears ...

Roberts syndrome: clinical and cytogenetic aspects.

Cellular and molecular aspects of organotin-induced thymus atrophy.

1. Organotin compounds, di-n-butyltin dichloride (DBTC) in particular, have been shown to cause thymus atrophy in the rat. 2. DBTC-induced thymus atrophy results from a depletion of small CD4+CD8+ thymocytes which is caused by a diminished production of immature CD4-CD8+ and CD4+CD8+ thymoblasts. 3. DBTC inhibits the activation, but not the differentiation of immature CD4-CD8+ thymocytes in vit...

Cellular Aspects of Immunity

was later verified principally by others. One may note his theories of the relationship of viruses to cancer as an example: Viruses may cause cancer by making cells unresponsive to normal control mechanisms, or possibly, by transducing abnormal genes from one cell to another or, perhaps, the so-called cancer viruses may actually be abnormal genetic material derived from the first host. The pref...
