- The differential cross section for the H-1(d, pp)n breakup reaction at deuteron beam energy of 340 MeV has been measured with the use of the WASA detector at COSY-Jillich. The set of proton-proton coincidences registered at the Forward Detector has been analyzed on a dense grid of kinematic variables, giving in total around 5600 data points. The cross-section data are compared to theoretical predictions based on the state-ofthe-art nucleon-nucleon potentials, combined with a three-nucleon force or the Coulomb interaction or carried out in a relativistic regime.

- To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.

- Nineteen nondiabetic kidney graft patients treated with cyclosporin A for 2 years underwent percutaneous renal allograft biopsy as well as renal hemodynamic examination. Renal allograft fibrosis was quantitatively evaluated as the relative volume of the renal cortical interstitium (VV %) and as the interstitium/tubuli ratio (I/T ratio). The histological changes were then classified into four groups, depending on the degree of interstitial fibrosis. The glomerular filtration rate (GFR), renal plasma flow (RPF), renal blood flow (RBF), filtration fraction (FF), and fractional clearance of sodium, potassium, phosphate, chloride, osmoles, and free water clearance were determined in all patients and in 13 healthy controls. Kidney graft recipients had significantly lower GFR, lower RPF, and lower RBF than the healthy controls (P < 0.001 for all comparisons) while FF was similar in patients and controls. Transplant recipients had a significantly higher fractional excretion of sodium, potassium, chloride, and phosphate than controls. All except one patient had clearly increased VV values, indicating increased interstitial fibrosis. The mean VV in renal allograft patients was 35% ± 10% (normal < 16% ± 5%) and the I/T ratio was 1.07 ± 0.60 (normal < 0.24 ± 0.08). No correlation was found between the quantitative or semiquantitative biopsy analysis and any renal hemodynamic parameter measured. We conclude that renal function is significantly decreased in kidney graft recipients, but that adaptive tubular changes occur in the graft. Interstitial renal fibrosis was common but did not correlate to any renal functional parameter.
