L. Apuleius Madaurensis. The Metamorphoses. A commentary on book III with text & introduction.

In his "Aspects of the Novel" (first ed. 1927, many reprints) E.M. Forster divided the characters which may be found in a novel into flat and round characters. (...) We may therefore conclude that curiositas is an important element in the whole story, but its religious meaning should not be overestimated. ... Zie: Appendi

Management of Cytomegalovirus Infection and Disease after Solid-Organ Transplantation

Cytomegalovirus (CMV) continues to be a cause of substantial morbidity and death after solid-organ transplantation. There are 3 major consequences of CMV infection: CMV disease, including a wide range of clinical illnesses; superinfection with opportunistic pathogens; and injury to the transplanted organ, possibly enhancing chronic rejection. This article discusses the considerable progress that has been made in elucidating risk factors for CMV disease, in the rapid detection of CMV in clinical specimens, and in the use of antiviral chemotherapy and immunoglobulin to prevent and treat CMV disease after solid-organ transplantatio

Epidemiology and Management of Infections after Lung Transplantation

Lung transplantation has become an accepted treatment for end-stage pulmonary parenchymal and vascular diseases. Infections still are the most common cause of early and late morbidity and mortality in lung transplant recipients. Bacterial infections comprise approximately half of all infectious complications. Cytomegalovirus (CMV) infections and disease have become less frequent, because of prophylaxis with ganciclovir. Because CMV is also involved in the pathogenesis of obliterative bronchiolitis, the frequency of this infection may also reduce the occurrence of this main obstacle to successful lung transplantation. Invasive fungal infections remain a problem, but they have also decreased in frequency because of better control of risk factors such as CMV disease and preemptive antifungal therapy. Nonherpes respiratory viral infections have emerged as a serious problem. Their severity may be reduced by treatment with ribavirin. Meticulous postoperative surveillance, however, is still crucial for the management of lung transplant patients with respect to early detection and treatment of rejection and infectio

Effects of RNA branching on the electrostatic stabilization of viruses

Many single-stranded (ss) RNA viruses self assemble from capsid protein subunits and the nucleic acid to form an infectious virion. It is believed that the electrostatic interactions between the negatively charged RNA and the positively charged viral capsid proteins drive the encapsidation, although there is growing evidence that the sequence of the viral RNA also plays a role in packaging. In particular the sequence will determine the possible secondary structures that the ssRNA will take in solution. In this work, we use a mean field theory to investigate how the secondary structure of the RNA combined with electrostatic interactions affects the efficiency of assembly and stability of the assembled virions. We show that the secondary structure of RNA may result in negative osmotic pressures while a linear polymer causes positive osmotic pressures for the same conditions. This may suggest that the branched structure makes the RNA more effectively packaged and the virion more stable
