The title compound, [Ca(C4H4O6)].4H2O, calcium tartrate tetrahydrate, is a new triclinic centrosymmetric form identified in rat kidney calculus. The crystal structure was determined from powder and single-crystal X-ray diffraction. The four water molecules belong to one square face of the Ca-atom coordination (a square antiprism), the four O atoms of the second square face coming from two tartrate anions, building infinite chains alternating Ca atom polyhedra and tartrate anions along a, with the chains cross-linked by a network of hydrogen bonds.

In liver, but not in heart, the fructose-enriched diet induces an early tissue-specific reduction in PPAR gamma and delta expression, which is insensitive to n-3 PUFA intake and dissociated from lipogenesis.

A single administration of sTNFR-Fc at the time of reperfusion after myocardial infarction is able to limit infarct size and to reduce early LV diastolic dysfunction in rats. These findings suggest that intravenous neutralization of TNF-alpha during surgical cardiac reperfusion might improve the outcome of myocardial infarction in humans.
