Mammary ducts are formed through a process of branching morphogenesis. We present results of experiments using a simulation model of this process, and discuss their implications for understanding mammary duct extension and bifurcation. The model is a cellular automaton approximation of a reaction- diffusion process in which matrix metalloproteinases represent the activator, inhibitors of matrix metalloproteinases represent the inhibitor, and ...

Early detection of breast cancer is an important task for preventing the loss of lives/breasts of the women. In this paper we propose a method for detecting suspicious features of breast cancers on mammograms by the combination of multiscale image filtering and regression-line analysis. Images are represented and analyzed at different scales. Calcifications are detected on the finest resolution, masses and mammary glands are detected on a more abstracted plane. After detecting mammary glands, we apply linear regression to the parts of mammary ducts, and estimates the degree of concentration by the measure of average minimal distance to the concentration point. Experimental results on the DDSM mammography images demonstrate that these approaches could contribute to the successful detection of these features.
Mastitis, inflammation of the mammary glands of the cows, causes big financial losses in milk production each year. As these losses have been calculated to reach $50 million US in several countries, a good screening method for the rapid detection of mastitis helps minimize this problem. The determination of the somatic cell content of milk is a valuable means of detecting mastitis. Conventional methods used to estimate it include electronic cell counting and microscopy techniques. The presence of several chemical compounds in milk, has also been suggested as providing the basis for new screening methods to detect mastitis. One of the most promising of these methods is that described in this paper: the determination of the number of somatic cells in milk using bioluminescence analysis. So, this detection system can be used directly by the own cattleman without the need of waiting for the reports of the Laboratory.
Mammary ducts are formed through a process of branching morphogenesis. We present results of experiments using a simulation model of this process, and discuss their implications for understanding mammary duct extension and bifurcation. The model is a cellular automaton approximation of a reaction- diffusion process in which matrix metalloproteinases represent the activator, inhibitors of matrix metalloproteinases represent the inhibitor, and growth factors serve as a substrate. We compare results from the simulation model with those from in-vivo experiments as part of an assessment of whether duct extension and bifurcation during morphogenesis may be a consequence of a reaction-diffusion mechanism mediated by MMPs and TIMPs.
In this paper we present a method for the spatial analysis of complex cellular systems based on a multiscale study of neighborhood relationships. A function to measure those relationships, M, is introduced. The refined relative neighborhood graph is then presented as a method to establish vicinity relationships within layered cellular structures, and particularized to epithelial cell nuclei in the mammary gland. Finally, the method is illustrated with two examples that show interactions within one population of epithelial cells and between two different populations.
For detecting the corners of the mammary gland blood oxygen image effectively, using the improved SUSAN+CSS corner detector algorithm in the image. In this method, firstly, remove the noise of the image by the morphology open operation and median filtering; secondly, segment the image by the threshold based on the gray value of the image and transform to the structure chart image, then detect the corners with the improved SUSAN corner detector algorithm; finally, combine these corners and get the corners of the mammary gland image with the CSS. The results show that the method can detect the corners of the mammary gland image effectively, which can offer some available parameters for the diagnosis of breast tumor.
Microwave radiometry is the spectral measurement technique of resolving the electromagnetic radiation of all matter whose temperature is above absolute zero. This technique utilized the electromagnetic noise field generated by a thermal volume similar to a mechanism existing in biological tissues. One particular application of microwave radiometry is for analyzing the temperature differentials inside the human body to detect and diagnose some crucial pathologic conditions. For general evaluation of radiometers, we propose a new mammary gland tumor phantom simulating the heat diffusion propagated by tissues around tumors. Theoretical researches of human tumors have revealed the fact that the temperature distribution of tissues around a tumor forms gaussian statistics. To comply with this physiological property, we built a tumor imitator composed of two parts, pseudo-tumor and thermo- anomaly, and observed the temperature distribution of the tumor imitator inside a phantom. Our experimental results showed that the thermal properties of the tumor imitator well agreed with heat transfer properties of a real tumor.
The cancer of the breast is the type of cancer that touches more of women in the world. Nowadays, one appraises that one out of ten women has a risk to be touched by this type of cancer. The best means to fight against this illness is through prevention by the precocious tracking slant. Through the intermediary of mammographic exams, these exams permit to discover the different lesions of the breast (microcalcification) and has a primordial role in the struggle against the cancer of the breast. It is in this setting that several works have started to come in to help radiologists at the time of their diagnoses. In this context, our work consists of two well-known complex problems, improvement by filtering and enhancement, whose feasibility remains to be proven again. We present in this article a technique of enhancement and GIF filtering in order to detect microcalcificationses while achieving a more effective algorithm.
This paper discussed the lethal effects of steep pulsed electric field (SPEF) to target lymphatic capillaries in VX2 implanted breast cancer of rabbits using methylene blue dye injection staining, 5'-AMP-ALPase enzyme histochemical double staining, electron microscopy and VEGF-C observations. The result of methylene blue dye perfusion showed that the edge of tumor treated with SPEF was indistinct, no circularity or liner structure. Enzyme histochemical staining examination displayed that no positive staining was found in SPEF-target region of breast tumor, and lymphatic capillaries presented piecemeal structure in the edge of target region. Transmission electron microscopic examination showed that the continuity and integrality of lymphatic capillaries in tumor were destroyed after the treatment of SPEF. The expression of VEGF-C decreased markedly. The experiment indicated that SPEF induced the severe destruction of tumor cell and lymphatic capillaries in target region, and inhibited proliferation of lymphatic. Therefore it can decrease the possibility of lymphatic metastasis
We present two methods for automatic registration of microscope images of consecutive tissue sections. They represent two possibilities for the first step in the 3-D reconstruction of histological structures from serially sectioned tissue blocks. The goal is to accurately align the sections in order to place every relevant shape contained in each image in front of its corresponding shape in the following section before detecting the structures of interest and rendering them in 3D. This is accomplished by finding the best rigid body transformation (translation and rotation) of the image being registered by maximizing a matching function based on the image content correlation. The first method makes use of the entire image information, whereas the second one uses only the information located at specific sites, as determined by the segmentation of the most relevant tissue structures. To reduce computing time, we use a multiresolution pyramidal approach that reaches the best registration transformation in increasing resolution steps. In each step, a subsampled version of the images is used. Both methods rely on a binary image which is a thresholded version of the Sobel gradients of the image (first method) or a set of boundaries manually or automatically obtained that define important histological structures of the sections. Then distance- transform of the binary image is computed. A proximity function is then calculated between the distance image of the image being registered and that of the reference image. The transformation providing a maximum of the proximity function is then used as the starting point of the following step. This is iterated until the registration error lies below a minimum value.
The authors propose to build equipment for hyperthermia which could be utilized together with radiotherapy or chemotherapy in the treatment of mammary gland cancer and dermic carcinoma. The project consists of three parts: the first was the design, development, and construction of the equipment; the second, taking place now, is experimentation with animals and phantoms, the third will be the application of the equipment to oncologic patients. The equipment provides local, RF hyperthermia.<<ETX>>
