[Learning to die/practice means learning about life with an awareness of death].
Living with the understanding that one must take leave of life means being able to restore the past. Living with the understanding that one must take leave of life means new insight into the present. Living with the understanding that one must take leave of life means creating an inspiring future. These three theorems are discussed in detail based on conversations with elderly persons.

Molecular characterisation of a predominant antigenic region of Giardia lamblia variant surface protein H7.
During infection, the intestinal protozoan parasite Giardia lamblia undergoes continuous antigenic variation which is determined by diversification of the parasite's major surface antigen, named VSP (variant surface protein). One member from this protein family, VSP H7, is expressed by G. lamblia clone GS/M-83-H7. In the present study, we characterised a highly antigenic portion of VSP H7 which is positioned inside a 130 amino acid C-terminal region of the protein. This region overlaps with a cysteine-rich motif that is rather conserved within the VSP family. Detailed molecular dissection of the antigenic portion monitored a 12 amino acid peptidyl structure which constitutes a non-conformational epitope of VSP H7. In the murine host, this epitope is recognised relatively early (before day 10 p.i.) during infection and stimulates a strong intestinal immunoglobulin A response. At late infective stages (after day 10 p.i.) this immune reaction is progressively complemented by reactions against 'late' antigenic epitopes which are also located inside the 130 amino acid antigenic portion but in closer proximity to the C-terminal end of VSP H7 than the 12 amino acid epitope. Both the high antigenicity and the conserved character suggest that the 12 amino acid epitope is a key factor within the immunological interplay between G. lamblia and the experimental murine host.

Wilhelm Ebstein and Ebstein's malformation.
In 1866, Wilhelm Ebstein published a scholarly description of a tricuspid valve anomaly with dilation of the right atrium and patent foramen ovale that bears his name. However, his original report was almost overlooked. Despite a wide range of publications on the history of cardiac pathology and cardiac surgery, the international literature provides only scarce information regarding the personality of Wilhelm Ebstein and his original description of the anomaly that bears his name. In this article, we present biographical data of Wilhelm Ebstein and discuss how his original description of autopsy findings correlates with our current knowledge of this congenital disorder. It is the excellent correlation of Ebstein's pathologic findings with clinical notes of his colleague and Ebstein's hypotheses of the pathophysiology that made his publication a landmark in the description of a new entity. In addition, Ebstein's report provided a strong basis for the development of repair techniques for this rare anomaly 100 years later.

Diagnosis of Neospora caninum and Toxoplasma gondii infection by PCR and DNA hybridization immunoassay.
A recently described PCR test for the identification of Neospora caninum and Toxoplasma gondii has been further developed and optimized in view of its practicability for routine diagnostic application. The N. caninum-specific PCR was adapted to the diagnostic operating standard of the T. gondii-specific PCR in that the uracil DNA glycosidase system was introduced, which eliminates potential carry-over contaminations of amplified target DNA from previous reactions. Furthermore, both PCR tests were optimized by including a DNA hybridization immunoassay based on the use of the commercially available Gen-eti-k DEIA kit. This assay allowed highly sensitive and specific detection of respective DNA amplification products and thus substantially facilitated the reading and interpretation of the test results.

Percutaneous absorption, metabolism, and hemolytic activity of n-butoxyethanol.
A series of studies was conducted to examine the percutaneous absorption, distribution, excretion, and hemolytic activity of n-butoxyethanol (BE). Rats receiving a subcutaneous dose of 14C-labeled BE excreted the radioactivity in the urine (79%), expired air (10%), and feces (0.5%) within 72 hr. Of the organs analyzed, thymus and spleen showed elevated specific radioactivities as compared with blood. A percutaneous application of BE on rats, under nonocclusive conditions, showed 25-29% absorption within 48 hr. Peak blood levels of BE occurred at 2 hr after application; butoxyacetic acid (BAA) was found to be the major metabolite. Comparison of in vitro skin penetration data showed the following absorption pattern of BE: hairless rat much greater than pig greater than human skin. Hemolysis and associated hematological changes were noted in the rats which received single dermal applications of 260-500 mg/kg of BE. In vitro, BAA showed markedly greater hemolytic ability on rat erythrocytes than did BE. Human erythrocytes showed no hemolysis when incubated with BE or BAA at concentrations that are hemolytic to rat erythrocytes. An intravenous dose of 62.5 mg/kg of BE does not result in hemolysis or hemoglobinuria in the rat. The rat may be an animal model with increased susceptibility to the effects of BE compared with humans because of its rapid percutaneous absorptive ability and its greater hemolytic sensitivity.
