MicroRNAs as regulators of tumor metabolism
No full textCancer cells reprogram their metabolism to support their growth. Since the discovery of the Warburg effect, several other metabolic alterations and metabolites have been described in cancer cells, including lactate, glutamine, and lipid metabolism reprogramming. Together these alterations provide rapidly dividing tumor cells with metabolic intermediates needed for nucleotide, protein, and fatty acid biosynthesis. MicroRNAs are a class of small non-coding RNAs involved in the regulation of virtually all biological pathways. Altered microRNA expression patterns are associated with the onset and development of several diseases, including cancer. Tumor suppressor microRNAs targeting molecules involved in tumor metabolism are frequently downregulated in cancers. Therefore, microRNAs can serve as potential tumor biomarkers and also represent interesting therapeutic targets. This review summarizes recent findings about microRNAs involved in the regulation of tumor metabolism
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Intraseasonal variability in the southwestern Arabian Sea and its relation to the seasonal circulation
No full textAn analysis of TOPEX/POSEIDON altimeter data and in situ current and temperature data obtained between April 1995 and October 1996 from a moored array shows strong intraseasonal fluctuations in the southwestern Arabian Sea, an oceanic region where the Great Whirl (GW), a predominantly wind-generated, very energetic anticyclone, is present during the Southwest Monsoon. Fluctuation periods between 30 and 50 days, up to 100 days during some years, are observed in the 8-year altimetric dataset, mostly during late summer and fall. These fluctuations are largest in a 1000 km-wide region off the Somali, Omani and Yemeni coasts north of 5°N, suggesting a local generation mechanism. The in situ data at different moorings show strong and coherent fluctuations that are characterized by southwestward phase propagation and northward energy propagation. Their periods range from 30 to 60 days and increase steadily from July 1995 to January 1996. In the first stage, these periods are at and below the cut-off period of freely propagating, first baroclinic mode Rossby waves, but approach this theoretical limit later in the year. Instabilities of the flow in the transition region between the Southern Gyre and the GW are likely sources of these fluctuations

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Analysis of the DNA mismatch repair proteins expression in malignant melanomas
No full textThe importance of properly functioning DNA mismatch repair has been shown in several tumour types both hereditary and sporadic but not yet in malignant melanomas. The aim of this study was to examine the expression of DNA mismatch repair genes (MLH1, MSH2, PMS1 and PMS2) in primary melanomas and to define their possible prognostic impact in 106 primary melanomas. MLH1 was found in 64 and MSH2 in 61 out of 106 melanomas. PMS1 and PMS2 proteins were present in 69 and 67 tumours, respectively. Loss of the expression of DNA mismatch repair proteins correlated with the increase of Clark levels. Cox regression analysis demonstrated some prognostic significance for PMS1 (forward p = 0.0018 and backward selections p=0.0277), MLH1 (only forward selection p =0.0081) and MSH2 (only backward selection p =0.0115)
