Let the dust settle: Impact of enhanced rock weathering on soil biological, physical, and geochemical fertility.

Terrestrial enhanced rock weathering (ERW) is a promising carbon dioxide removal technology that consists in applying ground silicate rock such as basalt on agricultural soils. On top of carbon sequestration, ERW has the potential to raise the soil pH and release nutrients, thereby improving soil fertility. Despite these possible co-benefits, concerns such as heavy metal pollution or soil structure damage have also been raised.

Urinary ethyl glucuronide (EtG) and ethyl sulphate (EtS) assessment: valuable tools to improve verification of abstention in alcohol-dependent patients during in-patient treatment and at follow-ups.

Aims: The aims of this study were (i) to assess the effect of additional urinary ethyl glucuronide (EtG) and ethyl sulphate (EtS) assessment on diagnosed relapse rates in detoxified alcohol-dependent patients; and (ii) to compare dropout rates between EtG- and EtS-negative and -positive patients.

Design: Two studies on detoxified alcohol-dependent patients. If patients had no indication of relapse they were asked for a urinary sample at discharge from in-patient treatment 3, 6 and 12 weeks after discharge (study 1) and 1, 3 and 6 weeks after discharge (study 2), respectively.

Gender differences for ghrelin levels in alcohol-dependent patients and differences between alcoholics and healthy controls.

Background: Ghrelin is a 28-amino acid gut-brain peptide, mainly secreted by the gastric mucosa. Its effects are linked to energy homeostasis and particularly seem to increase hunger and food intake. In recent years, studies suggested that appetite-regulating peptides, such as ghrelin play a relevant role in alcoholism.
