Direct interpretation of near-field optical images.

2001

The interpretation of the detection process in near-field optical microscopy is reviewed on the basis of a discussion about the possibility of establishing direct comparisons between experimental images and the solutions of Maxwell equations or the electromagnetic local density of states. On the basis of simple physical arguments, it is expected that the solutions of Maxwell equations should agree with images obtained by collecting mode near-field microscopes, while the electromagnetic local density of states should be considered to provide a practical interpretation of illumination mode near-field microscopes. We review collecting mode near-field microscope images where the conditions to o…

Peculiarities of imaging one- and two-dimensional structures using an electron microscope in the mirror operation mode.

2001

Measurements performed in an electron microscope with the mirror operation mode are most sensitive to local electric fields and geometrical roughness of any kind of the object being studied. The object with a geometrical relief is equivalent to a smooth surface with an effective distribution of microfields. Electrons forming the image interact with the local microfields for an extended time: during approach to the object, deceleration and acceleration away from the object. As a result, the electron trajectories can be strongly distorted, and the contrast changes essentially, leading to image deformation of details of the object under investigation and to lowering of the resolution. These ef…

Imprisoned But Innocent: Wrongful Convictions and Imprisonments in Germany, 1990-2016

2019

Although in the United States wrongful convictions and imprisonments are a major public and scientific concern, this topic has been largely ignored in Germany for decades. The present article offers for the first time an overview of all accessible German cases of successful retrials involving convicted persons who served a prison sentence since 1990. The data refer to 31 wrongfully convicted persons in 29 independent cases. Although the largest group consists of cases of false allegations, some of the wrongly convicted were considered not guilty by reason of insanity, and a few wrongful convictions occurred because of eyewitness misidentification and false confessions. In addition, incorre…

Tödliche Hundebisse im Sektionsgut rechtsmedizinischer Institute

2001

Hundebisse werden im angelsachsischen Raum als ernstes medizinisches, soziales und legislatorisches Problem angesehen, wohingegen in der deutschsprachigen Literatur nahezu keine Angaben uber die Inzidenz derartiger, insbesondere letal ausgehender Verletzungen zu finden sind. Zur Gewinnung von Daten uber todliche Hundebiss-Vorfalle in einem ungefahr 10 Jahre umfassenden Zeitraum wurde ein Fragebogen an alle rechtsmedizinischen Institute in Deutschland, der Schweiz und Osterreich versandt. Aus 13 Instituten wurden 20 Falle berichtet, unter denen 11-mal als Todesursache Verbluten und 3-mal eine schwere Infektion genannt wurden. Funfmal war es zu einem Schadel-Hirn-Trauma und 7-mal zu einer Hal…

Extranodal extension of lymph node metastasis is a marker of poor prognosis in oesophageal cancer: A systematic review with meta-analysis

2016

The extranodal extension (ENE) of nodal metastasis is the extension of neoplastic cells through the nodal capsule into the perinodal adipose tissue. This histological feature has recently been indicated as an important prognostic factor in different types of malignancies; in this manuscript, we aim at defining its role in the prognosis of oesophageal cancer with the tool of meta-analysis. Two independent authors searched SCOPUS and PubMed until 31 August 2015 without language restrictions. The studies with available data about prognostic parameters in subjects with oesophageal cancer, comparing patients with the presence of ENE (ENE+) versus only intranodal extension (ENE-), were considered…

Mothers who killed or attempted to kill their child: life circumstances, childhood abuse, and types of killing.

1999

The objectives of the present study were to examine the life circumstances, childhood abuse, and types of homicidal acts of 48 mothers who killed/attempted to kill their children) under age 12 between 1970-96 in Finland. Data on the mothers’ life stresses, psychological problems, and childhood abuse were collected from mental state examination (MSE) reports. The cases were divided into 15 neonaticides and 33 mothers who killed an older child. Childhood abuse was documented in 63% of the mothers’ MSE reports. Qualitative analysis identified neonaticides, joint homicide-suicide attempts, impulsive aggression, psychotic acts, postpartum depression, and abusive acts. Nonlinear principal compone…

The predictive and incremental validity of the German adaptation of the Static-2002 in a sexual offender sample released from the prison system

2015

Purpose The aim of this study was to examine the predictive validity of the German adaptation of the Static-2002 and to compare it with the results of the Static-99. Method The predictive validity of Static-2002 was investigated in a sample of n = 452 sexual offenders released from the Austrian Prison System. The instrument was coded retrospectively using file information. Afterwards, the predictive estimates of the Static-2002 were related to officially documented reconviction data. Results The Static-2002 was found to have large effect sizes for predicting sexual, violent, and general recidivism (area under the receiver operating characteristic curve [AUC] = .78, .75, .75, respectively) f…

Molecular Alterations of the RBI, TP53, and MDM2 Genes in Primary and Xenografted Human Osteosarcomas

1997

We report the status of the RBI, TP53, and MDM2 genes in human osteosarcomas and cell lines established from surgical specimens and transplanted into athymic naked mice. By using reverse transcriptase-polymerase chain reaction (RT-PCR) as a prescreening technique and posterior sequencing, we observe

Ischemic Preconditioning: Postischemic Structural Changes in the Brain

2008

Ischemic brain damage can be prevented or at least significantly reduced when there is a preceding brief ischemic period that does not exceed the threshold for tissue damage--a phenomenon termed "ischemic preconditioning" (ischemic PC). Experimental PC in rodents is now considered to be a model for transient ischemic attacks in humans, and there is increasing hope for translating the knowledge of underlying mechanisms in the animal models into the clinic to enhance endogenous neuroprotective mechanisms in patients with stroke. However, although PC was originally defined as a subtoxic stimulus without any morphologic damage, there is a growing body of evidence from studies using sensitive te…
