Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...
In a retrospective study of 126 cases of infiltrating ductal adenocarcinoma of the breast the percentage area of sections of each neoplasm occupied by malignant cells was assessed by morphometry. The duration of postoperative survival was related to the area occupied by tumour cells within a neoplasm; the greater the tumour cell area to stroma the more prolonged the survival. This variable seem...
The study includes 16 cases of Warthin's tumor in a period of 4 years (2004-2008). The tumors were diagnosed at patients of VII decade, most of them smoker. The studies of Warthin's tumor macroscopic morphological parameters allow us to establish the localization exclusive at parotid glands like solitary tumor and the tumoral volume oscillate mostly between 2-4 cm in diameter. Histopathological...
in this study, the effect of hormon ovafact (gnrha) on biological semen characteristics (motility duration, percentage of motile spermatozoa, spermatocrit, sperm density, milt volume, ph, na+, k+, ca+, mg2+, total protein, cholesterol and glucose) in sub species commons, comets, wakins and fantail goldfish (carassius auratus gibelio) males was compared. from each treatment ten males has been in...
A combined nonlinear optical microscopy (NLOM) and optical coherence microscopy (OCM) imaging system has been assembled in order to simultaneously capture co-registered volumetric images of corneal morphology and biochemistry. Tracking of cell nuclei visible in the OCM volume enabled the calculation of strain depth profile in response to changes in intraocular pressure for rabbit cornea stroma....
The poor clinical outcome in pancreatic ductal adenocarcinoma (PDA) is attributed to intrinsic chemoresistance and a growth-permissive tumor microenvironment. Conversion of quiescent to activated pancreatic stellate cells (PSCs) drives the severe stromal reaction that characterizes PDA. Here, we reveal that the vitamin D receptor (VDR) is expressed in stroma from human pancreatic tumors and tha...
Background: For the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, MRSI was used as a molecular imaging modality with MRI and CT images. Materials and Methods: The images of 20 prostate cancer patients were used in this study. The MR and MRSI images were registered with CT ones using non-rigid registration technique. The CT based planning (BP), CT/MR...
Gully erosion is one of the causes of land degradation, which causes a lot of damage with the loss of fertile soil. For this purpose, in the present study, using the Cochran relation, 40 gullies were selected for measurement in the Mazayjan watershed located in the southeast of Fars province. Factor analysis method was used to determine the factors affecting the classification of samples. Backw...
Aims: Strong expression of CD 34 has been described in many tumors. It has been proposed that these lesions arise from long-lived mesenchymal cells. We tested the hypothesis that spindle cell lesions of the breast arise from similar mesenchymal cells in mammary stroma, and to determine the potential diagnostic value of CD 34 immunostaining in these lesions. Methods and results: Sections of fibr...
In this study, the dynamic buckling of the embedded laminated nanocomposite plates is investigated. The plates are reinforced with the single-walled carbon nanotubes (SWCNTs), and the Mori-Tanaka model is applied to obtain the equivalent material properties of them. Based on the sinusoidal shear deformation theory (SSDT), the motion equations are derived using the energy method and Hamilton's p...
