Studying Stem Rust and Leaf Rust Resistances of Self-Fertile Rye Breeding Populations.

Stem rust (SR) and leaf rust (LR) are currently the two most important rust diseases of cultivated rye in Central Europe and resistant cultivars promise to prevent yield losses caused by those pathogens. To secure long-lasting resistance, ideally pyramided monogenic resistances and race-nonspecific resistances are applied. To find respective genes, we screened six breeding populations and one testcross population for resistance to artificially inoculated SR and naturally occurring LR in multi-environmental field trials.

Comprehensive proteomic data sets for studying adipocyte-macrophage cell-cell communication.

Cellular communication is a fundamental process in biology. The interaction of adipocytes with macrophages is a key event in the development of common diseases such as type 2 diabetes. We applied an established bilayer cell co-culture system and comprehensive mass spectrometry analysis to detect proteome-wide the paracrine interaction of murine adipocytes and macrophages.

Amorfrutin B is an efficient natural peroxisome proliferator-activated receptor gamma (PPARγ) agonist with potent glucose-lowering properties.

Aims/hypothesis: The nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ) is an important gene regulator in glucose and lipid metabolism. Unfortunately, PPARγ-activating drugs of the thiazolidinedione class provoke adverse side effects. As recently shown, amorfrutin A1 is a natural glucose-lowering compound that selectively modulates PPARγ.

Correlations between first documented cardiac rhythms and preceding telemetry in patients with code blue events.

Background: Among in-hospital cardiac arrest (IHCA) patients, the first cardiac rhythm documented on resuscitation records (FDR) is often used as a surrogate for arrest etiology. Although the FDR generally represents the electrical activity at the time of cardiopulmonary resuscitation initiation, it may not be the ideal rhythm to infer the arrest etiology. We hypothesized that a rhythm present earlier-at the time of the code blue call-would frequently differ from the FDR, because the FDR might represent the later stage of a progressive cardiopulmonary process.

Foam cell specific LXRα ligand.

Objective: The liver X receptor α (LXRα) is a ligand-dependent nuclear receptor and the major regulator of reverse cholesterol transport in macrophages. This makes it an interesting target for mechanistic study and treatment of atherosclerosis.

Methods And Results: We optimized a promising stilbenoid structure (STX4) in order to reach nanomolar effective concentrations in LXRα reporter-gene assays.
