| 11[beta]-hydroxysteroid dehydrogenase type-2 (11[beta]-HSD2) regulates the local concentration of cortisol that can activate the glucocorticoid receptor and mineralocorticoid receptor, as well as the concentration of 11-keto-testosterone, the active androgen in fish. Similarly, 17[beta]-HSD2 regulates the levels of testosterone and estradiol that activate the androgen receptor and estrogen receptor, respectively. Interestingly, although human 11[beta]-HSD2 and 17[beta]-HSD2 act at different positions on different steroids, these enzymes are paralogs. Despite the physiological importance of 11[beta]-HSD2 and 17[beta]-HSD2, details of their origins and divergence from a common ancestor are not known. An opportunity to understand their evolution is... |

| Zum Themenkreis „Pflanzenschutz im Ökologischen Landbau – Probleme und Lösungsansätze“ führt das JKI seit 1998 regelmäßig spezielle Fachgespräche durch. Ziel ist es, umfassende Informationen zum Pflanzenschutz anzubieten, geeignete Verfahren des Pflanzenschutzes vorzustellen und die Entwicklung von Mitteln und Methoden für den Ökologischen Landbau zu fördern. Das 14. Fachgespräch wurde vom Institut für Strategien und Folgenabschätzung im Pflanzenschutz organisiert und ging um die Anwendung von Phosphonaten, insbesondere im Ökologischen Landbau. Phosphonate (Salze der Phosphonsäure) sind in der Natur weit verbreitete Stoffe und kommen in vielen Organismen natürlich vor. In Deutschland und Österreich sind sie in Pflanzenstärkungsmitteln enthalten und können... |

| This study investigates the N transfer from legumes to neighbouring plants, grasses, legumes and herbs in a temperate grassland. In a field experiment white clover (Trifolium repens), red clover (Trifolium pratense) and lucerne (Medicago sativa) were leaf-labelled with 15N enriched urea. The 15N tracer was measured in above-ground plant tissue of eight neighbouring plants in two subsequent harvests in 2008. The three legumes donated 15N to all neighbouring plants, of which grasses, white and red clover were strong receivers. Results show that N transfer increases with N application and from the 1st to the 2nd cut. |

| Average net farm income was $69,787 in 2009 for the 95 farms included in this annual report of the Southwestern Minnesota Farm Business Management Association. Average earnings decreased by 63% from $190,901 in 2008. This continues the downward trend that began in 2008 after six years of steady increases. As expected, low incomes for virtually all types of livestock operations pulled the average down, and some livestock farms sustained large losses. Crop farms, on average, were profitable but also earned much lower incomes compared to recent years. Median net farm income, or the income earned by the middle farm, was $96,130, substantially higher than the average. This indicates that the average was pulled down or skewed by large losses sustained by... |
