A Fragment of the LG3 Peptide of Endorepellin Is Present in the Urine of Physically Active Mining Workers: A Potential Marker of Physical Activity

Biomarker analysis has been implemented in sports research in an attempt to monitor the effects of exertion and fatigue in athletes. This study proposed that while such biomarkers may be useful for monitoring injury risk in workers, proteomic approaches might also be utilised to identify novel exertion or injury markers. We found that urinary urea and cortisol levels were significantly elevated in mining workers following a 12 hour overnight shift. These levels failed to return to baseline over 24 h in the more active maintenance crew compared to truck drivers (operators) suggesting a lack of recovery between shifts. Use of a SELDI-TOF MS approach to detect novel exertion or injury markers revealed a spectral feature which was associated with workers in both work categories who were engaged in higher levels of physical activity. This feature was identified as the LG3 peptide, a C-terminal fragment of the anti-angiogenic/anti-tumourigenic protein endorepellin. This finding suggests that urinary LG3 peptide may be a biomarker of physical activity. It is also possible that the activity mediated release of LG3/endorepellin into the circulation may represent a biological mechanism for the known inverse association between physical activity and cancer risk/survival

The rank reversal problem in multi-criteria decision making : a literature review

Despite the importance of multicriteria decision-making (MCDM) techniques for constructing effective decision models, there are many criticisms due to the occurrence of a problem called rank reversal. Nevertheless, there is a lack of a systematic literature review on this important subject which involves different methods. This study reviews the pertinent literature on rank reversal, based on 130 related articles published from 1980 to 2015 in international journals, which were gathered and analyzed according to the following perspectives: multicriteria technique, year and journal in which the papers were published, co-authorship network, rank reversal types, and research goal. Thus our survey provides recommendations for future research, besides useful information and knowledge regarding rank reversal in the MCDM field

EXPERIMENTAL INVESTIGATION OF UREA-SCR IN C.I. ENGINE FUELLED WITH DIESEL AND JATROPHA BLENDS

Abstract: An Experimental Investigation was conducted to examine the performance and exhaust emission of diesel Engine by using Selective Catalytic Reduction (SCR) concept fuelled with diesel and Biodiesel namely Jatropha ( 25% of Jatropha and 75% Diesel blends). A test was conducted in four cylinder direct injection diesel engine with different loading condition. And the urea with distilled water solution was sprayed at the Exhaust manifold before it enters the SCR setup for different concentrations and the emission parameters were investigated are CO, HC, NO X and Smoke Opacity. Results showed that Biodiesel reduced the NO X and other emission. The result showed that the Biodiesel derived from jatropha oil showed comparable performance in the Selective Catalytic Reduction system (SCR). Results indicated that a maximum of 73.94% of NO X reduction was achieved with constant flow rate of 0.75 lit/hr with a urea concentration of 32.5% by means of the Titanium dioxide catalyst in Selective Catalytic Reduction (SCR) System
