in this study, isolate sr99-ua (race 70e 128) of wheat stripe rust (puccinia striiformis west. f. sp. tritici eriks) was used to infect susceptible spring wheat (cultivar thatcher) and its near isogenic line possessing yr-18 adult-plant resistance gene. samples were taken at the flag leaf stage and observed using light, transmission and scanning electron micro-scopes. no major differences in th...

In a recent publication we described a microscopical technique called Ultramicroscopy, combined with a histological procedure that makes biological samples transparent. With this combination we can gather three-dimensional image data of large biological samples. Here we present the theoretical analysis of the z-resolution. By analyzing the cross-section of the illuminating sheet of light we der...

background and objective: histological grading has prognostic and therapeutic implications in meningioma. however, histological criteria are sometimes not fulfilled to predict the biological behavior of meningiomas. p63 gene is a novel p53 family member, known as tumor suppressor factor, with multiple isoforms and shows high expression in many normal and neoplastic human tissues. in this study,...

background: colorectal adenocarcinoma is one of the most prevalent and treatable malignancies of the gastrointestinal tract. pattern of expression of the p53, p21, p16, e-cadherin and |î²|-catenin proteins are shown to be related to the prognosis of this malignancy. we aimed to compare the pattern of expression of these proteins in tumoral and nontumoral mucosal cells of cancer and on-cancer pa...

In this paper we prove that the extended triplicate graph (ETG) of finite paths admits product E-cordial, total product E-cordial labelings. We show that ETG of finite paths of length n where n ∉ {4m-3|m∈N} admits E-Cordial, total E-cordial labelings and also we prove the existence of Z3 – magic labeling for the modified Extended Triplicate graph.

background and objectives: cyclooxygenese-2 (cox-2) expression in breast cancer and its correlation with tumor prognosis is unclear. we investigated the incidence of cox-2 expression in patients and assessed interactions between cox-2 and clinical features of cancer and expression of her2/neu, estrogen receptor (er), and progesterone receptor (pr). methods: cox-2 expression was investigated by...

Introduction: One of the most important complications of exposure to noises is changes in the gene expression patterns. Irreversible damage to the inner ear, such as noise-induced hearing loss (NIHL), is caused by tissue damage and changes in the gene expressions in the auditory system. Changes in the GJB2 gene expression pattern lead to autosomal deafness at different loci. The present study a...

objective(s): to investigate the expression of human papilloma virus (hpv) l1 capsid protein, and human telomerase rna component (hterc) in cervical cancer and the role of detection of both genes in screening of cervical cancer.   materials and methods: a total of 309 patients were recruited and cervical exfoliated cells were collected. immunocytochemistry was employed to detect hpv l1 capsid p...
