Purpose: To investigate the effects of split dose irradiation on primary and metastatic uveal melanoma cell lines using a clonogenic survival assay. Methods: Appropriate cell concentrations of four primary and four metastatic human uveal melanoma cell lines were cultured for irradiation with single doses and with two equal fractions separated by 5 h. After irradiation colony formation was allow...

259 Lines are protected by overcurrent-, distance-, or pilot-relaying equipment, depending on the requirements. Overcurrent relaying is the simplest and cheapest, the most difficult to apply, and the quickest to need readjustment or even replacement as a system changes. It is generally used for phaseand ground-fault protection on station-service and distribution circuits in electric utility and...

Introduction: Midbrain dopaminergic neurons are involved in various brain functions, including motor behavior, reinforcement, motivation, learning, and cognition. Primary dopaminergic neurons and also several lines of these cells are extensively used in cell culture studies. Primary dopaminergic neurons prepared from rodents have been cultured in both DMEM/F12 and neurobasal mediums in several ...

primary-like and weakly primary-like submodules are two new generalizations of primary ideals from rings to modules. in fact, the class of primary-like submodules of a module lie between primary submodules and weakly primary-like submodules properly.  in this note, we show that these three classes coincide when their elements are submodules of a multiplication module and satisfy the primeful pr...

PURPOSE RASSF1A, a recently identified candidate tumor suppressor gene, was found to be inactivated in lung cancer and other tumor types. We sought to understand the role of RASSF1A in head and neck cancer. EXPERIMENTAL DESIGN We analyzed the status of RASSF1A and presence of high-risk human papilloma virus (HPV) in head and neck cancer squamous cell carcinoma (HNSCC) cell lines and primary t...

objective: multiple myeloma (mm) is a plasma cell malignancy where plasma cells are increased in the bone marrow (bm) and usually do not enter peripheral blood, but produce harmful factors creating problems in these patients (e.g. malignant plasma cells over activate osteoclasts and inhibit osteoblasts with factors like rankl and dkk). these factors are a main cause of bone lesion in mm patient...

The VLSI technology has led to the increased complexity in hardward design, therefore the verification for the correctness of circuit operations has become an exrtremely important task. The verification procedure can be reduced by means of the equivalent signal lines in the circuits. In this paper, a new method is presented for determining the equivalent signal lines, the method utilizes the we...

The Ewing tumor family of peripheral primitive neuroectodermal tumors (pPNETs) are characterized by chromosomal translocations leading to EWS-ETS gene fusions. These hybrid genes express chimeric proteins that are thought to act as aberrant transcription factors. We therefore used differential display-PCR to compare gene expression patterns in pPNET cell lines with those of other small round ce...

let r be a commutative ring and m be an r-module. we say that m is fully primary, if every proper submodule of m is primary. in this paper, we state some characterizations of fully primary modules. we also give some characterizations of rings over which every module is fully primary, and of those rings over which there exists a faithful fully primary module. furthermore, we will introduce some ...

Suppression of p21 has been implicated in the genesis and progression of many human malignancies. DNA methylation is an important mechanism of gene silencing in human malignancies. In this study, we examined the expression status and aberrant methylaion of p21 in lung cancers and malignant pleural mesotheliomas (MPM). We used 12 small cell lung cancer (SCLC) cell lines, 13 non-small cell lung c...
