Sterols of grapefruit,orange, and mandarin pulps

The composition and percentage distribution of the sterols in preparations of the free (I), glycosylated (II), and esterified (III) sterols in the pulp of citrus fruits have been studied. In the sterol preparations, cholesterol, campesterol, stigmasterol, and β-sitosterol have been identified and detected, and three other sterols have been detected but not identified. It has been established that the sequences of the relative amounts of sterols in preparations (I), (II), and (III) of the grapefruit and the orange are similar and differ from that of mandarin pulp.     

Differential Scanning Calorimetry and Hydrodynamic Study of Bacterial Viruses. About possible heat effects in hermetically closed calorimetric vessels with free volume above the liquid

The phase transitions occurring in aqueous solutions of macromolecules and their complex structures (like order-disorder transitions in proteins or nucleic acids solutions) are usually accompanied by small changes in their specific partial volumes. If the quantity of these substances in the closed calorimetric vessels is relatively large (few mg) and if the phase transition is accompanied by a high change of specific partial volume (like in solution of bacteriophages),it is possible to detect some imaginary heat effects in the DSC calorimeters which have closed (sealed) vessels with free volume above the liquid. This revised version was published online in July 2006 with corrections to the Cover Date.
