The web application Isotopica has been developed as an aid to the interpretation of ions that contain naturally occurring isotopes in a mass spectrum. It allows the calculation of mass values and isotopic distributions based on molecular formulas, peptides/proteins, DNA/RNA, carbohydrate sequences or combinations thereof. In addition, Isotopica takes(More)
Growth hormone secretagogues (GHS) such as ghrelin induce an array of effects in different types of organisms. The role of ghrelin in immune cell activation includes the release of pro-and anti-inflammatory cytokines via different signaling pathways [1,2]. For example, murine RAW 264.7 macrophages express both ghrelin and GHS receptors. Treatment of these(More)

This research was directed toward predicting postural equilibrium configurations in normal humans for asymmetric locations of the feet. The objective of the study was to identify trends in the variation of the location of ground center of pressure (COP) with increasing levels of asymmetry in the foot placement. The procedure developed here minimized the(More)
