Determination of Platinum-Group Elements (PGE) from catalytic converters in soil by means of docimasy and INAA.

1996

The nickelsulfide fire assay (docimasy) for the enrichment of platinum-group elements (PGEs) has been modified for the use with small samples and combined with instrumental neutron-activation analysis (INAA). This procedure has been applied to the determination of PGEs exhausted from catalytic converters and deposited in soil near the Wiesbadener Kreuz (highway A3, Frankfurt-Koln). Our results show a considerable enhancement of the Pt (up to 330 ng/g), Pd (6.6 ng/g) and Rh (7.5 ng/g) contents close to the highway.

Child maltreatment by nursing staff and caregivers in German institutions: A population-representative analysis.

2019

Abstract Background Child maltreatment by caregivers seem to make a significant contribution to general maltreatment rates. Interestingly, research assessing prevalence rates of maltreatment mainly focuses on individual components either in relation to different types of maltreatment or in relation to different types of institutions. Objective The current study assesses prevalence rates for child maltreatment by caregivers in hospitals, rehabilitation centers, facilities for the disabled, schools, Kindergartens, and after-school care or residential care. Participants and setting: In a cross-sectional survey, a representative sample of the German population above the age of 14 (N = 2,516) wa…

Prevalence, correlates, and predictors of depersonalization experiences in the German general population.

2009

The survey aimed to investigate the prevalence of depersonalization (DP) experiences, its sociodemographic characteristics and its associations with medical conditions, illness behavior, and potential etiologic factors. A representative face-to-face household survey was conducted. The sample consists of n = 1,287 participants aged 14 to 90 years. Sociodemographic variables, medical conditions, current mental disorders, health care utilization, and childhood adversities were assessed. A total of 1.9% participants scored in the range of clinically significant DP (DP-C) and 9.7% reported at least some impairment through DP (DP-I). DP-C/DP-I were strongly associated with depression and anxiety.…

Childhood Adversities and Adult Headache in Poland and Germany.

2015

Objective Various childhood adversities have been found to be associated with chronic pain in adulthood. However, associations were moderate in most studies, i.e. odds ratios (OR) were between one and two. Method An internet survey was performed in 508 Polish and 500 German subjects. A total of 19 childhood adversities were selected and their associations with headaches explored. Age, gender and country were included as potential confounders, as well as their two-way interaction with the risk factors. Results Two strong risk factors were identified. (1) A combined score for physical and emotional neglect showed an odds ratio (OR) of 2.78 (p < .002) to the frequency of headache in adulthood …

Impact of the COVID-19 pandemic on incidence, time of diagnosis and delivery of healthcare among paediatric oncology patients in Germany in 2020: Evi…

2021

ABSTRACT Background The indirect impact of the COVID-19 pandemic on cancer care and timely diagnosis is of increasing concern. We investigated the impact of the COVID-19 pandemic on incidence, time of diagnosis and delivery of healthcare among paediatric oncology patients in Germany in 2020. Methods We analysed incident paediatric cancer cases diagnosed in 0- to 17-year olds in Germany in 2020 using data of the German Childhood Cancer Registry. Absolute numbers and age-standardised incidence rates (ASR) in 2020 were compared to the previous five years (2015–2019). Moreover, we conducted a survey with open-ended questions, gathering perceptions of the diagnostic process and healthcare delive…

Molecular Characterization and Source Identification of Atmospheric Particulate Organosulfates Using Ultrahigh Resolution Mass Spectrometry.

2019

Organosulfates (OSs) have been observed as substantial constituents of atmospheric organic aerosol (OA) in a wide range of environments; however, the chemical composition, sources, and formation mechanism of OSs are still not well understood. In this study, we first created an "OS precursor map" based on the elemental composition of previous OS chamber experiments. Then, according to this "OS precursor map", we estimated the possible sources and molecular structures of OSs in atmospheric PM2.5 (particles with aerodynamic diameter ≤ 2.5 μm) samples, which were collected in urban areas of Beijing (China) and Mainz (Germany) and analyzed by ultrahigh-performance liquid chromatography (UHPLC) c…

Molecular biology, China and the West

2000

More than 15 years ago, in November 1985, I travelled to China for the first time. I joined a symposium on developmental biology in the Shanghai Institute of Cell Biology (CBI), organised by the Chinese Academy of Sciences and the Max‐Planck‐Gesellschaft in Germany. The symposium was meant to provide perspectives for the future of the Max Planck Guest Laboratory, just founded in the CBI. When I attended, I did not anticipate that my visit to Shanghai would initiate a long‐term commitment to China. I did not even expect to return to China in the near future. But early in 1987, my colleague Uli Schwarz from the Max Planck Institute of Developmental Biology in Tubingen, who was and still is in…

Tracing anthropogenic thallium in soil using stable isotope compositions.

2014

Thallium stable isotope data are used in this study, for the first time, to apportion Tl contamination in soils. In the late 1970s, a cement plant near Lengerich, Germany, emitted cement kiln dust (CKD) with high Tl contents, due to cocombustion of Tl-enriched pyrite roasting waste. Locally contaminated soil profiles were obtained down to 1 m depth and the samples are in accord with a binary mixing relationship in a diagram of Tl isotope compositions (expressed as e(205)Tl, the deviation of the (205)Tl/(203)Tl ratio of a sample from the NIST SRM 997 Tl isotope standard in parts per 10(4)) versus 1/[Tl]. The inferred mixing endmembers are the geogenic background, as defined by isotopically l…

Comparative analysis of short tandem repeats and single nucleotide polymorphisms on the Y-chromosome in Germans, Chinese and Thais.

2003

We have typed genomic DNA samples from 95 individuals from Western Germany, 78 individuals from Bangkok/Thailand and 56 individuals from Chengdu/China for 11 Y-chromosomal diallelic polymorphisms and eight short tandem repeat (STR) systems. For single nucleotide polymorphism (SNP) analysis, a rapid method was applied using the single base extension technology (minisequencing) in combination with capillary electrophoresis. PCR products for SRY-8299, Tat, SRY2627, 92R7, SRY1532, M9, M13, M17/M19 and M20 were pooled and used as templates for the commercially available SNaPshot kit. In addition to these ten SNPs we also tested the Y-chromosomal diallelic Alu repeat insertion DYS287 (YAP) by aga…
