Laura Crispini; Maria-Luce Fre`zzotti, 1998: Fluid inclusion evidence for progressive folding during decompression in metasediments of the Voltri Group (Western Alps, Italy). Quartz veins syntectonic to distinct folding events in metasediments from the Voltri Group (Ligurian Alps) were studied in order to compare fluid and structural evolution. Studied veins (VS1, VS2, VS3) pertain to three distinct generations of fold...

Tiefenbacher, C.P., 2001: Tetrahydrobiopterin: a critical cofactor for eNOS and a strategy in the treatment of endothelial dysfunction?. A number of recent studies indicate that tetrahydrobiopterin could be a new and an effective therapeutical option in the treatment of endothelial dysfunction. On the basis of biochemical observations, these findings have been confirmed using in vi...

In patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) with thrombus aspiration, the histopathology of aspirated thrombus was previously related to long-term mortality. In th...

Background: The common practice is to treat bacterial urinary tract infections (UTI) in young women with suitable antibiotics for 3 days. Our purpose in the present analysis was to test whether 3 days of treatment were as effective as 5 days or mo...

Based on nannoflora, the Upper Maastrichtian and Paleocene sequence was divided into several biozones. The latest Maastrichtian, Micula prinsii Zone and the Earliest Danian, Markalius inversus Zone (NPI) were recorded, and thus, St. Paul section i...

Variability in female estrus expression has been identified as a barrier to captive panda reproduction [Lindburg and Millard, 1995]. In China, researchers have reported that 80% of female giant pandas in captivity exhibit "weak estrus,"...

Hernando, V.; Sanchez Conde, P., 1959: Effect of the Ca/K ratio of the soil on the development of iron chlorosis.. In water-culture experiments with wheat, 18 Ca/K ratios (1: 128 to 128: 1) were compared, with the concentration of the elements varying from 0 to 3, 200 ppm. Ratios between 1: 8 and 16: 1 produced best growth. Chlorosis appeared with high Ca and...
