The purpose of this study is to evaluate our institutional outcomes for percutaneous nephrostomy tube placement in pregnant patients, including potential complications that require early exchange. Our standard routine exchanges non-pregnant patients 6 weeks. This aims define a time interval patients. A retrospective chart and imaging review was conducted 51 who received between January 1, 2012,...

Abstract In this study, a new assemblage of Ediacaran metazoan fossils is reported from the basal Stáhpogieddi Formation on Digermulen Peninsula Arctic Norway, including Anulitubus n. gen. Moczyd?owska in et al., formosus sp. Coniculus elegantis Fistula and crenulata al. The specimens are three-dimensionally preserved include tubular conical skeletons that morphologically distinguished by their...

We hypothesised that raising the abdominal pressure could provide a non-manual approach to opening urinary valve, with potential application for indwelling catheters or an intraurethral device. The ‘Vysera’ valve remains closed during short high amplitude spikes but opens when pre-defined low-amplitude is maintained pre-specified duration, allowing sustained straining achieve voluntary opening....

Recent studies of bacterial Fe(II) oxidation at circumneutral pH by a newly-isolated lithotrophic β-Proteobacterium (strain TW2) are reviewed in relation to a conceptual model that accounts for the influence of biogenic Fe(III)-binding ligands on patterns of Fe(II) oxidation and Fe(III) oxide deposition in opposing gradients of Fe(II) and O2. The conceptual model envisions complexation of Fe(II...

The formation of oxalates in soils and rocks under conditions cryoarid climate, permafrost taiga vegetation was studied. Whewellite weddellite were found four areas associated with the mining industry: on kimberlite deposit Daldyn territory, lower reaches Markha River Central Yakut Plain, coastal outcrop Allah-Yun Sellah-Khotun ore cluster. upper organic horizon Skeletic Cryosol (Thixotropic) (...

This study focuses on two main questions: (1) what types of shell damage occur in the death assemblage of upper Chesapeake Bay benthic mollusks; and (2) how does shell damage differ according to intrinsic factors such as life habit, shell mineralogy, and shell organic content. Extrinsic and intrinsic factors, ranging from the environment to shell composition, interact to influence the quality o...

The fossil record of the subsurface biosphere is sparse. Results obtained on subsurface filamentous fabrics (SFF) from >225 paleosubsurface sites in volcanics, oxidized ores, and paleokarst of subrecent to Proterozoic age are presented. SFF are mineral encrustations on filamentous or fibrous substrates that formed in subsurface environments. SFF occur in association with low-temperature aqueous...

Microbial nitrate-dependent, Fe(II) oxidation (NDFO) is a ubiquitous biogeochemical process in anoxic sediments. Since most microorganisms that can oxidize Fe(II) with nitrate require an additional organic substrate for growth or sustained Fe(II) oxidation, the energetic benefits of NDFO are unclear. The process may also be self-limiting in batch cultures due to formation of Fe-oxide cell encru...
