Microbial Ecology of Mid‐Ocean Ridges and Back‐Arc Basins
Over the past two decades, microbiologists have gained significant insights into the diversity and physiology of microbial communities associated with deep-sea hydrothermal systems. Much of the… Expand

Microbial diversity of a sulphide spire located in the Edmond deep-sea hydrothermal vent field on the Central Indian Ridge
A culture-independent molecular phylogenetic survey was carried out for a bacterial and archaeal community of a mineralized crust coating a sulphide spire, which was collected from the Edmond vent… Expand

Effect of hydrogen limitation and temperature on the fractionation of sulfur isotopes by a deep-sea hydrothermal vent sulfate-reducing bacterium
Abstract The fractionation of sulfur isotopes by the thermophilic chemolithoautotrophic Thermodesulfatator indicus was explored during sulfate reduction under excess and reduced hydrogen supply, and… Expand

Isotopic links between atmospheric chemistry and the deep sulphur cycle on Mars
The geochemistry of Martian meteorites provides a wealth of information about the solid planet and the surface and atmospheric processes that occurred on Mars. The degree to which Martian magmas may… Expand

Preclinical and clinical experiences with the role of somatostatin receptors in the treatment of pituitary adenomas
The patho-physiological role of somatostatin receptor subtypes (sst) in neuro endocrine diseases has gained enhanced scientific interest in the past few years. The development of novel… Expand

Temperature effect on the sulfur isotope fractionation during sulfate reduction by two strains of the hyperthermophilic Archaeoglobus fulgidus.
Sulfur isotope fractionation during dissimilatory sulfate reduction by two strains of the thermophilic archaeon Archaeoglobus fulgidus (strains VC-16 and Z) was explored over the entire temperature… Expand

Early inner solar system origin for anomalous sulfur isotopes in differentiated protoplanets
Significance This investigation focuses on the sulfur isotopic compositions of magmatically differentiated meteorites, the oldest igneous rocks in our solar system. We present evidence of anomalous… Expand

Pharmacokinetic‐pharmacodynamic comparison of a novel multiligand somatostatin analog, SOM230, with octreotide in patients with acromegaly
Acromegaly is a serious hormonal disorder resulting from a pituitary adenoma causing excess growth hormone (GH) production. Somatostatin analogs such as octreotide have been the medical treatment of… Expand

The Role of Somatostatin Analogs in Cushing's Disease
Somatostatin (SRIF) has been proposed to be of therapeutic interest in the medical treatment of Cushing's disease. While in vitro data demonstrate the presence of SRIF-receptor subtype (sst)… Expand

Controls on Isotope Fractionation During Dissimilatory Sulfate Reduction
Sulfur isotopes are fractionated during dissimilatory sulfate reduction; therefore, sulfur isotope studies have been useful in elucidating the role of sulfate reduction in the sulfur cycle, and in… Expand
