The origin and emplacement of the Freetown Intrusion, Sierra Leone Open
The Freetown Intrusion in Sierra Leone is a large, layered mafic intrusion. Only a small part of the intrusion appears on land to form the Freetown Peninsula, and the larger part lies beneath the Atlantic Ocean. This is demonstrated by gra…

Generation of Alkalinity by Stimulation of Microbial Iron Reduction in Acid Rock Drainage Systems: Impact of Natural Organic Matter Types Open
To determine the role of organic matter in the attenuation of acid rock drainage (ARD), microcosm-based experiments were performed using ARD stimulated with plants and manures. Initial mineralogical, organic geochemical and microbial analy…

Enhanced Analgesic Effects and Gastrointestinal Safety of a Novel, Hydrogen Sulfide-Releasing Anti-Inflammatory Drug (ATB-352): A Role for Endogenous Cannabinoids Open
Aims: The covalent linking of nonsteroidal anti-inflammatory drugs to a hydrogen sulfide (H2S)-releasing moiety has been shown to dramatically reduce gastrointestinal (GI) damage and bleeding, as well as increase anti-inflammatory and anal…

Graphite to Graphene: From a Mineral to an Advanced Technological Material Open
Carbon is one of a small number of elements that occur in the “native” state. The two most dominant naturally occurring forms of carbon are graphite and diamond, and these could hardly be more different in their properties: diamond is the …

Paratracheal force, cricoid pressure and obstetric anaesthesia Open
We congratulate Gautier et al. on their interesting paper comparing the effect of left paratracheal force applied to the oesophagus with cricoid pressure 1. Their finding that left paratracheal force was more effective than cricoid force i…

A proof‐of‐concept, Phase 2 clinical trial of the gastrointestinal safety of a hydrogen sulfide‐releasing anti‐inflammatory drug Open
Background and Purpose ATB‐346 is a hydrogen sulfide (H 2 S)‐releasing anti‐inflammatory and analgesic drug. Animal studies demonstrated negligible gastrointestinal (GI) damage despite marked inhibition of COX activity and significant anal…

Mineralogy of Sulfides Open
Metal sulfides are the most important group of ore minerals. Here, we review what is known about their compositions, crystal structures, phase relations and parageneses. Much less is known about their surface chemistry, their biogeochemist…

Effects of Microbial Fe(III) Reduction on the Sorption of Cs and Sr on Biotite and Chlorite Open
Microbially mediated reduction of Fe(III) in chlorite and biotite by Shewanella oneidensis MR-1 leads to a significant reduction in sorption of both Cs and Sr compared to the abiotic systems. As seen in previous studies, biotite is a more …
