The authors report three patients with abdominal pseudocysts and one with cerebrospinal fluid ascites as late complications of ventriculoperitoneal shunts. The presenting signs and symptoms were those of intraabdominal abnormality, with no neurological symptoms suggestive of shunt malfunction.
The fibroblast growth factor receptor FGFR2 is overexpressed in a variety of solid tumors, including breast, gastric, and ovarian tumors, where it offers a potential therapeutic target. In this study, we present evidence of the preclinical efficacy of BAY 1187982, a novel antibody-drug conjugate (ADC). It consists of a fully human FGFR2 monoclonal antibody(More)
In this paper it will be shown that the deposition method is an important parameter for the electrical properties of the metal gate. Indeed, ALCVD(Atomic Layer Chemical Vapor Deposition) TiN metal has a 5.3eV workfunction, suitable for PMOS devices. The PVD sputtered (Physical Vapor Deposition) TiN has a lower workfunction around 4.8eV and is mid-gap like.(More)
This report describes a new method for the determination of protein binding and relative protein binding (ratio of f(u) for different species) for compounds strongly bound to proteins. The method used is based on the distribution of the drug in plasma water, plasma proteins, and blood cells. Incubations were performed in diluted plasma. In diluted plasma,(More)
Novel cyclohexadienes have been identified as potent and specific IK(Ca)-channel blockers. In this communication we describe their synthesis as well as their chemical and biological properties. A selected derivative is being enriched in rat brain and reduces the infarct volume, intracranial pressure as well as the water content in a rat subdural hematoma(More)
Early deterioration and death after brain injury is often the result of oedema in the injured and peri-lesional tissue. So far, no pharmacotherapy is available that exhibits significant brain oedema-reducing efficacy in patients. We selected two low molecular weight compounds from different chemical classes, a triazole(More)
Some cases of occurrence of matrix effects (mostly ion suppression) in protein-precipitated plasma samples, and their influence on the validity of plasma concentrations and pharmacokinetic parameters, are discussed. The comparison of matrix effects using either electrospray (TurboIonspray, TISP) or atmospheric pressure chemical ionization (APCI) indicated(More)
The reaction of 2-alkenals with GSH to form GSH conjugates by Michael addition is a major detoxification pathway. The reaction proceeds at a much higher rate under catalysis by glutathione S-transferase (GST) than the non-enzymatic reaction. Oxidation of 2-alkenals to the corresponding acids by cytosolic and microsomal fraction of rat liver also contributes(More)
The pseudopeptide pyrrolidinedione antibiotics, such as moiramide B, have recently been discovered to target the multisubunit acetyl coenzyme A (acetyl-CoA) carboxylases of bacteria. In this paper, we describe synthetic variations of each moiety of the modularly composed pyrrolidinediones, providing insight into structure-activity relationships of(More)
For treatment of patients with prostate cancer (PCa), we developed a novel T cell-engaging (BiTE) antibody designated AMG 212 or BAY2010112 that is bispecific for prostate-specific membrane antigen (PSMA) and the CD3 epsilon subunit of the T cell receptor complex. AMG 212/BAY2010112 induced target cell-dependent activation and cytokine release of T cells,(More)
