The paper gives an overveiew of radioecological concepts, reference information on plants and soils used in the project. Main classification schemes applied to summarize the data on radionuclide transfer to plants are also described. Generic quantities and units used in the current document are also given. They are mainly defined according to the the ICRU 65 report. 1. DEFINITIONS, QUANTITIES A...

To gain insight into the role of the CCN genes in human breast carcinomas, we quantified connective tissue growth factor (CTGF), WISP-1, CYR61, and human NOV (NOVH) mRNA expression levels in samples from 44 primary breast tumors and seven normal breasts using quantitative real-time PCR assay. Overexpression of CTGF, WISP-1, CYR61, and NOVH was found in 55 (24 of 44), 46 (20 of 44), 39 (17 of 44...

BACKGROUND AND PURPOSE Conformal radiotherapy requires accurate dose calculation at the dose specification point, at other points in the planning target volume (PTV) and in organs at risk. To assess the limitations of treatment planning of lung tumours, errors in dose values, calculated by some simple tissue inhomogeneity correction algorithms available in a number of currently applied treatmen...

Telah dilakukan penelitian mengenai distribusi dosis radiasi foton pada Treatment Planning System (TPS) menggunakan teknik Three Dimension Conformal Radiotherapy (3DCRT) dan Intensity Modulation (IMRT) untuk terapi kanker serviks, ini bertujuan mengetahui yang mencangkup Target Volume (PTV) ) Cakupan melalui Conformity Index (CI) Homogeneity (HI) serta Normal Tissue to Integral Dose (NTID) jari...

Background: Ultrasound propagation velocity was measured experimentally in normal, fibroadenoma and ductal carcinoma breast tissues, in order to distinguish normal breast tissue from tumors. Materials and methods: In quantitative measurements of ultrasound velocity, 403 breast tissue images were selected, comprising 130 normal breast tissue, 130 fibroadenoma, and 143 ductal carcinoma tumors. Th...

background : seroma formation is a common problem following axillary dissection. it is probably caused by a local inflammatory response. local steroids may prevent this problem by inhibiting inflammatory response at the wound site. methods : this randomized prospective study was undertaken to evaluate the effect of local triamcinolone injection on seroma formation following axillary dissection....

The levels of mRNA for transforming growth factors (TGF alpha and beta) and the epidermal growth factor receptor (EGFR) were determined in 69 human breast carcinomas and 20 biopsies of nonneoplastic breast tissue by dot blot hybridisation analysis. TGF alpha mRNA was detected in 42% of cancers and 44% of non-neoplastic breast tissue at low levels. TGF beta mRNA was found in all breast cancers a...

Breast cancer is one of the leading causes of fatality in women. Mammogram is the effectual modality for early detection of breast cancer. Increased mammographic breast density is a moderate independent risk factor for breast cancer, Radiologists have estimated breast density using four broad categories (BI-RADS) swearing on visual assessment of mammograms. The aim of this paper is to review ap...

introduction: of the factors leading to false negative results in mammography is breast tissue density, and by increasing the density of breast tissue in mammography, the mammography sensitivity decreases. on the other hand, increasing the breast tissue density leads to increased risk of breast cancer. various factors such as inheritance, genetics, hormonal and reproductive factors, and nutriti...
