Abstract The crystal chemistry and structure of the rare earth element phosphates, monazite-(Ce), Ce(PO 4 ), xenotime-(Y), Y(PO as well arsenates, gasparite-(Ce), Ce(AsO chernovite-(Y), Y(AsO from hydrothermal quartz-bearing fissures, related to pegmatites overprinted by amphibolite facies, cropping out at Mt. Cervandone, Western Alps, Piedmont, Italy, have been investigated means electron micr...
Abstract This study focuses on hydrothermal alteration in the geothermal reservoir of Cerro Pabellón (Andean Cordillera, Northern Chile). It is based CP2A and CP5A production wells drilled above a local normal fault presenting unlike hydraulic properties. Cuttings from 300 to 1555 m depth were sampled analyzed using X-ray diffraction (XRD) observe distribution minerals crystal chemistry variati...
Novel hyper-resistant bacteria were isolated from the Crven Dol mine (Allchar, North Macedonia), arsenic-rich extreme environment. Bacteria recovered a secondary mineral mixture, an alteration of hydrothermal realgar rich in arsenates (pharmacolite, hornesite, and talmessite). The sample was dark part at 28 m depth. Three bacterial strains consortium for their capacity to survive exposure 32 g/...

Metal organic frameworks (MOFs) are highly porous and crystalline coordination polymers that can be synthesized from a wide variety of metal-cluster nodes and a diverse selection of multitopic organic linkers. As a result, they are highly tailorable and different combinations of functionalities can be incorporated into the nodes and the linkers in an orthogonal manner. Not surprisingly, these m...
Amphibian populations are experiencing catastrophic declines driven by the fungal pathogen Batrachochytrium dendrobatidis (Bd). Although horizontal gene transfer (HGT) facilitates the evolution and adaptation in many fungi by conferring novel function genes to the recipient fungi, inter-kingdom HGT in Bd remains largely unexplored. In this study, our investigation detects 19 bacterial genes tra...
BACKGROUND An excess incidence of brain cancer in farmers has been noted in several studies. The National Institute for Occupational Safety and Health developed the Upper Midwest Health Study (UMHS) as a case-control study of intracranial gliomas and pesticide uses among rural residents. Previous studies of UMHS participants, using "ever-never" exposure to farm pesticides and analyzing men and ...
