Mortality Among Hardmetal Production Workers: Pooled Analysis of Cohort Data From an International Investigation.

Objectives: Based on a pooled analysis of data from an international study, evaluate total and cause-specific mortality among hardmetal production workers with emphasis on lung cancer.

Methods: Study members were 32,354 workers from three companies and 17 manufacturing sites in five countries. We computed standardized mortality ratios and evaluated exposure-response via relative risk regression analysis.

Mortality Among Hardmetal Production Workers: German Historical Cohort Study.

Objective: The aim of this study was to investigate a cohort in German hardmetal industry, especially relationship between exposures to cobalt, with and without tungsten, and risks of total and cause-specific mortality.

Methods: The cohort comprises blue-collar workers at three German plants who were employed in hardmetal processing. Individual cumulative exposures and long-term average concentrations were estimated for cobalt, nickel, tungsten, respirable, and inhalable dust.

Biological control of aragonite formation in stony corals.

Little is known about how stony corals build their calcareous skeletons. There are two prevailing hypotheses: that it is a physicochemically dominated process and that it is a biologically mediated one. Using a combination of ultrahigh-resolution threedimensional imaging and two-dimensional solid-state nuclear magnetic resonance (NMR) spectroscopy, we show that mineral deposition is biologically driven.

The Miller Range 090340 and 090206 Meteorites: Identification of New Brachinite-Like Achondrites with Implications for the Diversity and Petrogenesis of the Brachinite Clan.

Miller Range (MIL) 090340 and MIL 090206 are olivine-rich achondrites originally classified as ureilites. We investigate their petrography, mineral compositions, olivine Cr valences, equilibration temperatures, and (for MIL 090340) oxygen isotope compositions, and compare them with ureilites and other olivine-rich achondrites. We conclude that they are brachinite-like achondrites that provide new insights into the petrogenesis of brachinite clan meteorites.

Data donation after death: A proposal to prevent the waste of medical research data.

Biological data from deceased persons could be a rich resource for research, but is difficult to use owing to privacy and consent concerns. A Data Donation Card and registry would enable people to contribute their medical data to future research, even after their death. [Image: see text]

The chlorine isotope fingerprint of the lunar magma ocean.

The Moon contains chlorine that is isotopically unlike that of any other body yet studied in the Solar System, an observation that has been interpreted to support traditional models of the formation of a nominally hydrogen-free ("dry") Moon. We have analyzed abundances and isotopic compositions of Cl and H in lunar mare basalts, and find little evidence that anhydrous lava outgassing was important in generating chlorine isotope anomalies, because (37)Cl/(35)Cl ratios are not related to Cl abundance, H abundance, or D/H ratios in a manner consistent with the lava-outgassing hypothesis. Instead, (37)Cl/(35)Cl correlates positively with Cl abundance in apatite, as well as with whole-rock Th abundances and La/Lu ratios, suggesting that the high (37)Cl/(35)Cl in lunar basalts is inherited from urKREEP, the last dregs of the lunar magma ocean.

Risk behaviors and externalizing behaviors in adolescents dealing with parental cancer--a controlled longitudinal study.

Objective: The results of studies concerning levels of internalizing and externalizing behaviors in adolescent children with a parent suffering from cancer as compared with control groups or normative data are contradictory so far. Longitudinal designs using control groups are rare. No study explicitly exploring a broad range of risk behaviors in adolescent children with a parent suffering from cancer exists to date.

[Anticipatory grief in adolescents and young adults coping with parental cancer].

By the current state of research, it cannot be answered clearly how adolescents experience anticipatory grief and if and to which extent this process differs from anticipatory grief of adults. The present study will fill this gap by providing both a quantitative and a qualitative description of anticipatory grief processes. Therefore, 74 adolescents and young adults (11-21 years), whose parents have suffered from cancer, completed an adapted version of the "Trauerfragebogen" (Weiser u.
