In recent years concern has arisen whether carrying a cellular phone near the reproductive organs such as the testes may cause dysfunction and particularly decrease in sperm development and production, and thus fertility in men. The present study was performed to investigate the effects of a 1.95 GHz electromagnetic field on testicular function in male(More)
The aim of this study was to determine whether albumin leakage and dark neurons were present in rat brains 14 and 50 days after a single 2-h exposure to a 915 MHz electromagnetic field, as reported by Salford et al. (Environ. Health Perspect. 111, 881-883, 203). Sixty-four male F344 rats (12 weeks old) were exposed to a 915 MHz electromagnetic field at(More)
We describe a novel pharmacological activity of the gentian root, an ingredient of Chinese medicines. Root extract from Gentiana triflora triggered cell death of human Daudi cells in culture. In addition, daily administration of the extract to mice inhibited growth of implanted solid tumors. Extract treatment of cultured cells resulted in the appearance of(More)
Using vitrification and encapsulation-vitrification protocols, we successfully cryopreserved shoot apices from in-vitro plants of different Gentiana cultivars (lines). Although both protocols gave high survival percentages after storage in liquid nitrogen, the encapsulation-vitrification protocol had several distinct advantages over the vitrification(More)
Use of the third generation mobile phone system is increasing worldwide. This is the first study to investigate the effects of the third generation system on regional cerebral blood flow (rCBF) in humans. We compared effects of the electromagnetic field (EMF) emitted from the Wideband Code Division Multiple Access (W-CDMA) cellular system versus sham(More)
The binding of R 1881 in cytosols from the normal, benign hypertrophic and cancerous human prostates was examined in the presence of molybdate and triamcinolone acetonide. The addition of 10 mM Na2MoO4 resulted in an increase in the stability of the binder without any change in Kd. Triamcinolone acetonide added to the incubation of cytosol with R 1881(More)
We report a primary adrenal leiomyosarcoma in a 59-year-old man. Computed tomography demonstrated a poorly enhanced mass, measuring 10 cm, between the left kidney and the normal left adrenal gland, with tumor thrombus in the inferior vena cava (IVC). The patient underwent left radical nephroadrenalectomy with IVC thrombectomy. The histological diagnosis was(More)
Expression of the c-erbB-2 gene product and the epidermal growth factor receptor (EGF-R) was investigated in 54 cases of human bladder cancer immunohistologically and by Western blot analysis. For detection of the c-erbB-2 product, two specific antibodies, a rabbit polyclonal antibody directed to the intracellular domain and a murine monoclonal antibody(More)
We investigated the genetic basis for the derivation of pink coloration in petals from blue flowers in cultivated gentians. Using a revertant blue-flower phenotype that arose spontaneously from a pink-flowered cultivar, we sought to elucidate the molecular mechanism of flower color restoration caused by a suppressor mutation. Detailed sequencing analysis(More)
