There are some reports on the lignan constituents of Linum spp. In this study, we investigated the cyototoxicity of Linum spp. in vitro cultures for the first time. If they show significant cytotoxic activity, they will be valuable candidates for isolation of cytotoxic compounds in large scale from them by tissue culture technology. In our study, we chose normal root, hairy root and calli cultu...

skin cancer has a broad and burdensome impact on the health and well-being of iranian and account for substantial health care costs to the nation. the first most common form of skin cancer is basal cell carcinoma (bcc); followed by the squamous cell carcinoma (scc) and the incidence of malignant melanoma (mm) is lower but is fatal. kaposi sarcoma (ks) is a tumor caused by human herpes virus 8. ...

background and objective: basal cell carcinoma (bcc) and squamous cell carcinoma (scc) are two common tumors of the skin. in some cases, distinction between bcc and scc can be difficult. this study aimed to clarify this uncertainty through immunohistochemical analysis. in this respect, epithelial membrane antigen (ema) and ber-ep4 are the two immunohistochemical markers on which we focus in dif...

conclusions the findings of this study are consistent with the hypothesis that local, systemic, or tumor-induced immunosuppression may allow the mcpyv to initiate skin aggressive cancer. it is necessary to maintain regular check over patients taking immunosuppressive medications for mcpyv infection. since there is not any information about detection and molecular biology analysis of mcpyv among...

background: sulfur mustard (sm) has been considered as a carcinogen in the laboratory studies. however, its carcinogenic effects on human beings were not well discussed. the main purpose of our study is to assess carcinogenesis of sm following acute and/or chronic exposures in human beings. methods: the valid scientific english and persian databases including pubmed, web of science, scopus, ira...

Forty-six cases of primary bronchogenic carcinoma occurring in patients with other unilateral pleuropulmonary diseases were studied. In 37 cases (80-4%) carcinoma developed in the previously healthy lung. All but one squamous-cell carcinoma and all of five undifferentiated small-cell carcinomas developed in the previously healthy lung while 7 of 15 adenocarcinomas were in the lung with impaired...

Many studies demonstrated unique microRNA profiles in lung cancer. Nonetheless, the role and related signal pathways of miR-375 in lung cancer are largely unknown. Our study investigated relationships between carcinogenesis and miR-375 in adenocarcinoma, squamous cell carcinoma and small cell lung carcinoma to identify new molecular targets for treatment. We evaluated 723 microRNAs in microdiss...

BACKGROUND Lung Carcinoma is the leading causes of morbidity and mortality worldwide with an incidence of 1.3 million cases per year. This study was undertaken to determine prevalence of various histological types of lung carcinoma and to analyse their changing trends with time. METHODS This is a retrospective analytical study. A total of 330 cases of lung carcinoma were analysed from 2003 to...

background: invasive squamous cell carcinoma of the vulva is primarily a disease of postmenopausal women and thus is rarely associated with pregnancy. case: we have reported on a young woman under 40 years old with vulvar carcinoma, which occurred during the pregnancy but optimal treatment was delayed to the postpartum period. this 37-year-old woman was diagnosed with 3x3 cm vulvar lesion, 2 we...

Magnetic nanoparticles have been highly regarded because of their unique properties, such as hyperthermia, medicine control release, and diagnostic applications. The main aim of the current paper is to offer a new system for the modification of Fe3O4 (SPIONs) superparamagnetic nanoparticles physically and chemically with polymers through physical retention. These modified nanoparticles have bee...
