Small cell lung cancer (SCLC) is an aggressive disease, in which more than 80% of patients present distant metastases at the time of first diagnosis. Chemotherapy is considered as the main treatment of extensive disease of SCLC (ED-SCLC), while the role of radiotherapy in the treatment of ED-SCLC is controversial. A case-control study was undertaken of patients diagnosed as ED-SCLC between 2004...
OBJECTIVES Current National Comprehensive Cancer Network (NCCN) guidelines recommend thoracic consolidation radiation therapy (TCRT) for patients with Extensive Stage Small Cell Lung Cancer (ES-SCLC) with response to systemic chemotherapy, based on two randomized clinical trials, which varied in patient selection and radiation therapy doses administered. The current pattern of practice among US...
Background: Acute Necrotizing Mediastinitis (ANM) is a lethal disease that without antibiotic therapy and surgical Intervention has a mortality rate about 40% in best medical centers. With development of imaging technology (spiral CT- Scan) and shortening in time of diagnosis and surgery, the outcome and prognosis of the patients are improved. The surgical modalities are trans- cervical and tra...
Epigenome modulation potentially provides a mechanism for organisms to adapt, within and between generations. However, neither the extent to which this occurs, nor the mechanisms involved are known. Here we investigate DNA methylation variation in Swedish Arabidopsis thaliana accessions grown at two different temperatures. Environmental effects were limited to transposons, where CHH methylation...
The kinetics of the hydroxyl radical (OH) + carbon monoxide (CO) reaction, which is fundamental to both atmospheric and combustion chemistry, are complex because of the formation of the hydrocarboxyl radical (HOCO) intermediate. Despite extensive studies of this reaction, HOCO has not been observed under thermal reaction conditions. Exploiting the sensitive, broadband, and high-resolution capab...
BACKGROUND The Standard Tables of Food Composition in Japan do not include information on trans fatty acids. Previous studies estimating trans fatty acid intake among Japanese have limitations regarding the databases utilized and diet assessment methodologies. We developed a comprehensive database of trans fatty acid food composition, and used this database to estimate intake among a Japanese p...
Excess consumption of trans-fatty acid could increase the risk of non-alcoholic steatohepatitis (NASH); however, treatment targeting trans-fatty acid-induced NASH has not been examined. Here we focused on the influence of trans-fatty acid intake on endoplasmic reticulum (ER) stress in hepatocytes, so we investigated the effect of the chemical chaperone 4-phenylbutyric acid (PBA), on trans-fatty...
Various list accessing algorithms have been proposed in the literature and their performances have been analyzed theoretically and experimentally. Move-To-Front (MTF) and Transpose (TRANS) are two well known primitive list accessing algorithms. MTF has been proved to be the best performing online algorithm till date in the literature for real life inputs and practical applications with locality...
We study the reaction of atomic hydrogen with formic acid and characterize the radical products using IR spectroscopy in a Kr matrix and quantum chemical calculations. The reaction first leads to the formation of an intermediate radical trans-H2COOH, which converts to the more stable radical trans-cis-HC(OH)2via hydrogen atom tunneling on a timescale of hours at 4.3 K. These open-shell species ...
The relative position of exons in genes can be altered only after large structural mutations. These mutations are frequently deleterious, impairing transcription, splicing, RNA stability, or protein function, as well as imposing strong inflexibility to protein evolution. Alternative cis- or trans-splicing may overcome the need for genomic structural stability, allowing genes to encode new prote...
