The failure of long descending pathways to regenerate after spinal cord injury (SCI) is generally attributed to inhibitory proteins associated with the glial scar and myelin, or to the loss of neurons' intrinsic capacity to grow, or both. Here, we describe the use of hydrogels as a novel way to deliver molecules that promote axon growth in the injured CNS(More)
Iodine induced thyroid involution is caused by apoptosis rather than necrosis. This effect of iodide on apoptosis of thyroid epithelial cells may be not a direct one but mediated by iodinated derivatives i.e. of polyunsaturated fatty acids, especially of iodolactones, which have previously shown to inhibit thyroid cell proliferation. We studied the(More)
The ring of symmetric functions Λ, with natural basis given by the Schur functions, arise in many different areas of mathematics. For example, as the cohomology ring of the grassmanian, and as the representation ring of the symmetric group. One may define a coproduct on Λ by the plethystic addition on alphabets. In this way the ring of symmetric functions(More)
There is growing evidence that STW 5 (Iberogast), fixed combination of hydroethanolic herbal extracts), besides being effective in functional dyspepsia, also improves symptoms in irritable bowel syndrome (IBS). Clinical data indicate that modulation of mucosal secretion is a promising approach to treat intestinal disorders associated with IBS. We therefore(More)
This study correlates whole organ measurements of intracellular calcium concentration ([Ca(2+)](i)) with hormone-induced (epinephrine, vasopressin) changes of liver functions (glucose release, K(+) balance and bile flow). [Ca(2+)](i) was measured in the isolated perfused rat liver using the sensor Fura-2 and applying liver surface fluorescence spectroscopy.(More)
The effect of the cycloocygenase inhibitor indometacin (Indo) on the synthesis of prostacyclin-like substances (PGI2-LS) in human veins has been studied after in vivo and in vitro application of the drug. PGI2-LS were bioassayed by ADP-induced platelet aggregation during twenty minutes incubation time. We used human veins of varicose patients, which were(More)
Cylindric plane partitions may be thought of as a natural generalization of reverse plane partitions. A generating series for the enumeration of cylindric plane partitions was recently given by Borodin. As in the reverse plane partition case, the right hand side of this identity admits a simple factorization form in terms of the " hook lengths " of the(More)
