[Johannes Müller (1801-1858) and his school: pioneer and giant of German physiology].

Johannes Müller was indisputably the most versatile and brilliant physiologist in the mid-nineteenth century. Müller was born in Koblenz in 1801 as the eldest of five children. He received an excellent education in mathematics and the ancient languages and was thus able to read with ease the writings of Aristotle in the original.

AFM-Based Force Spectroscopy Guided by Recognition Imaging: A New Mode for Mapping and Studying Interaction Sites at Low Lateral Density.

Ligand binding to receptors is one of the most important regulatory elements in biology as it is the initiating step in signaling pathways and cascades. Thus, precisely localizing binding sites and measuring interaction forces between cognate receptor-ligand pairs leads to new insights into the molecular recognition involved in these processes. Here we present a detailed protocol about applying a technique, which combines atomic force microscopy (AFM)-based recognition imaging and force spectroscopy for studying the interaction between (membrane) receptors and ligands on the single molecule level.

Trigeminal Neuralgia and Multiple Sclerosis: A Historical Perspective.

Trigeminal neuralgia (TN) associated with multiple sclerosis (MS) was first described in Lehrbuch der Nervenkrankheiten für Ärzte und Studirende in 1894 by Hermann Oppenheim, including a pathologic description of trigeminal root entry zone demyelination. Early English-language translations in 1900 and 1904 did not so explicitly state this association compared with the German editions. The 1911 English-language translation described a more direct association.

Publications on Peripheral Nerve Injuries during World War I: A Dramatic Increase in Knowledge.

Publications from French (Jules Tinel and Chiriachitza Athanassio-Bénisty), English (James Purves-Stewart, Arthur Henry Evans and Hartley Sidney Carter), German (Otfrid Foerster and Hermann Oppenheim) and American (Charles Harrison Frazier and Byron Stookey) physicians from both sides of the front during World War I (WWI) contributed to a dramatic increase in knowledge about peripheral nerve injuries. Silas Weir Mitchell's original experience with respect to these injuries, and particularly causalgia, during the American Civil War was further expanded in Europe during WWI. Following the translation of one of his books, he was referred to mainly by French physicians.

Palbociclib in Hormone-Receptor-Positive Advanced Breast Cancer.

Background: Growth of hormone-receptor-positive breast cancer is dependent on cyclin-dependent kinases 4 and 6 (CDK4 and CDK6), which promote progression from the G1 phase to the S phase of the cell cycle. We assessed the efficacy of palbociclib (an inhibitor of CDK4 and CDK6) and fulvestrant in advanced breast cancer.

Methods: This phase 3 study involved 521 patients with advanced hormone-receptor-positive, human epidermal growth factor receptor 2-negative breast cancer that had relapsed or progressed during prior endocrine therapy.

In vitro efficacy of antibiotic beads in treating abdominal vascular graft infections.

Objective: Abdominal aortic vascular graft infection often involves several different organisms. Antibiotic polymethyl methacrylate (PMMA) beads may be effective in controlling infection after débridement, but bacterial species identification and antibiotic susceptibility are often not available at the time of operation, generating a need for a broad-spectrum drug combination for empirical use. We sought to determine an effective antibiotic in PMMA beads for use in abdominal vascular graft infection.

Dying to play video games: carbon monoxide poisoning from electrical generators used after hurricane Ike.

Background: Carbon monoxide (CO) poisoning is common after major storms because of loss of electrical power and use of alternate fuel sources for heat and electricity. In past epidemics of hurricane-related CO poisoning, the source has typically been gasoline-powered electrical generators. Although it is typically believed that generators were used to power air conditioning and refrigeration, this report demonstrates an unsuspected reason for their use.

Quantitative protein composition and baking quality of winter wheat as affected by late sulfur fertilization.

Increasing prices for wheat products and fertilizers, as well as reduced sulfur (S) contributions from the atmosphere, call for an improvement of product quality and agricultural management. To detect the impact of a time-dependent S fertilization, the quantitative protein composition and the baking quality of two different wheat cultivars, Batis and Turkis, were evaluated. The glutathione concentration in grains serves as a reliable marker of the need for added S fertilizer.

Dominant negative MORT1/FADD rescues mice from CD95 and TNF-induced liver failure.

Derangement of the apoptotic program is considered an important cause of liver disease. It became clear that receptor-mediated apoptosis is of specific interest in this context, and CD95 and CD120a, both members of the tumor necrosis factor (TNF) receptor superfamily, are the most prominent cell death receptors involved. The death signal is induced upon ligand binding by recruitment of caspases via the adapter molecule MORT1/FADD to the receptor and their subsequent activation.
