tumor size seems to be a determinant in the prognosis of early cervical cancer. patients with tumor size greater than 4 cm (bulky) in diameter have worse outcome.' the purpose of this study was to compare the efficacy of preoperative combined chemoradiation and neoadjuvant chemotherapy (narc) programs followed by radical hysterectomy in stage ib - lib bulky cervical cancer. from september ...

the oxidative stress causes many diseases in human, therefore antioxidants have a specialposition in the medicinal chemistry. tyrosol is an important antioxidant with a plenty ofbiological properties. there are many strategies such as clustering single drug units in orderto develop new drugs. the cluster effect can increase drug effects relative to single drug unit.calixtyrosol is the novel clu...

antibacterial, antifungal and antioxidant activities of methanolic crude extracts from aerial parts of four arnebia species namely arnebia fimbriopetala, arnebia linearifolia, arnebia garandiflora, arnebia tubata were screened. total phenolic contents were determined by folin-ciocalteu procedure and ranged from 2.2 ± 0.13 (a. fimbriopetala) to 1.6 ± 1.0 mg (arnebia tubata) gallic acid µmol equi...

background there is an interest in finding new and safe antioxidants from natural sources such as medicinal plants. objectives the aim of this study was to evaluate the antioxidant activity of ten iranian medicinal plants extracts. materials and methods for antioxidant activity, the radical scavenging activity, reducing power and phenolic contents of ethanol plant extracts were determined. gall...

background: modified radical mastectomy (mrm) is still one of globally accepted surgical techniques for breast cancer and in some selected patient is the gold standard type of surgery. the most frequent complication of this procedure is seroma under skin flaps or in the axilla as reported as much as 30% in some studies. the use of closed suction drainage system to reduce the incidence of this c...

background: primary leiomyosarcoma (lms) of the breast is a very rare neoplasm of the breast arising from the mesenchymal tissue. the clinical presentation of this entity simulates other benign and malignant lesions of mesenchymal tissue of the breast. case presentation: case 1: a 40-year-old female presented with a right-sided breast lump, which was suspected to be a malignant spindle cell tum...

the spectroscopic properties of the 2,2,6,6-tetramethyl-piperidine-1-oxyl (tempo) radicalderivatives of the fullerene (c60) were theoretically investigated. the ground state optimizedstructures of the radical adducts of the fullerene were calculated by using dft (b3lyp) with 6-31g(d) level. it was concluded that a 6-6 ring junction of c60 moiety generally covalently links to thepiperidine ring ...
