The bacterial flora in the teat duct of ewes can protect against and can cause mastitis
(2007)We studied the possible effects of bacterial populations within the teat duct, in the pathogenesis of ovine mastitis. In experiment I, 32 ewes were allocated into group A (ewes from which we isolated (+++ growth) ... -
Breast Cancer Classification on Multiparametric MRI – Increased Performance of Boosting Ensemble Methods
(2022)Introduction: This study aims to assess the utility of Boosting ensemble classification methods for increasing the diagnostic performance of multiparametric Magnetic Resonance Imaging (mpMRI) radiomic models, in differentiating ... -
Computer-based automated estimation of breast vascularity and correlation with breast cancer in DCE-MRI images
(2017)Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) with gadolinium constitutes one of the most promising protocols for boosting up the sensitivity in breast cancer detection. The aim of this study was twofold: ... -
Contrast-enhanced and unenhanced diffusion-weighted imaging of the breast at 3 T
(2018)Aim: To evaluate the effect of intravenous gadolinium contrast agent on diffusion-weighted sequences and apparent diffusion coefficient (ADC) measurements at 3 T. Materials and methods: Sixty-two biopsy-proven breast lesions ... -
Diagnostic performance of quantitative diffusion tensor imaging for the differentiation of breast lesions at 3 T MRI
(2019)Background: Conventional breast magnetic resonance imaging (MRI), including dynamic contrast-enhanced MR mammography, may lead to ambiguous diagnosis and unnecessary biopsies. Purpose: To investigate the contribution of ... -
Efficacy of Mannan-Oligosaccharides as Alternatives to Commonly Used Antibiotic Growth Promoters in Broilers
(2021)The present study was conducted to evaluate the efficacy of mannan oligosaccharides (MOS) as alternatives to antibiotic growth promoters (AGP) in broiler diets. Two hundred day-old Hubbard broiler chicks were randomly ... -
Electron density of tissues and breast cancer radiotherapy: A quantitative CT study
(1998)Purpose: To obtain more accurate data on the electron density of tissues to be used in the treatment planning of breast cancer patients. Methods and materials: Single kV(p) quantitative computed tomography was applied in ... -
Immunohistochemical expression of extracellular matrix components tenascin, fibronectin, collagen type IV and laminin in breast cancer: their prognostic value and role in tumour invasion and progression
(2002)The immunohistochemical expression of the extracellular matrix (ECM) components tenascin (TN), fibronectin (FN), collagen type IV (Coll) and laminin (LN), and their possible relationships were studied in a series of 134 ... -
Incorporating diffusion-weighted imaging in a diagnostic algorithm for multiparametric MR mammography
(2022)Background: Apparent diffusion coefficient (ADC) measurements are not incorporated in BI-RADS classification. Purpose: To assess the probability of malignancy of breast lesions at magnetic resonance mammography (MRM) at 3 ... -
Reproducibility of apparent diffusion coefficient measurements evaluated with different workstations
(2018)Aim To evaluate apparent diffusion coefficient (ADC) measurements of breast lesions on different computer platforms to address post-processing influences on ADC measurement reproducibility. Materials and methods One hundred ... -
Survivin regulation by HER2 through NF-kappa B and c-myc in irradiated breast cancer cells
(2011)Radiotherapy is an important treatment modality against cancer resulting in apoptosis and inhibition of cell growth. Survivin is an important cancer biomarker conferring to tumour cells increased survival potential by ...
