Hypersulfidic deep biosphere indicates extreme sulfur isotope fractionation during single-step microbial sulfate reduction

Cultural Transformation in the Geoscience Community AND Program Evaluation

Bernasconi SM, Böttcher ME, Wortmann UG.
GSID: r4PibTEGnD4J
UG Wortmann, SM Bernasconi, ME Böttcher - Geology, 2001 - pubs.geoscienceworld.org

Coexisting dissolved sulfide and sulfate from hypersulfidic interstitial waters of a 380-m-long sediment core show a large isotopic difference of up to 72‰ caused by in situ microbial sulfate reduction. This is considerably larger than the assumed biological maximum...

First report of splenic rupture following deep enteroscopy.

World journal of gastrointestinal endoscopy

Girelli CM, Pometta R, Facciotto C, Mella R, Bernasconi G.
PMID: 27170840
World J Gastrointest Endosc. 2016 May 10;8(9):391-4. doi: 10.4253/wjge.v8.i9.391.

Splenic rupture is a rare complication of diagnostic and therapeutic gastrointestinal endoscopy procedures. Herein, we report for the first time a case of splenic rupture following therapeutic retrograde double-balloon enteroscopy, which occurred in an 85-year-old man who was treated...

PMID: 26955645
Open Forum Infect Dis. 2016 Feb 01;3(1):ofw022. doi: 10.1093/ofid/ofw022. eCollection 2016 Jan.

Background.  Limited data exist on human immunodeficiency virus (HIV)-infected individuals' ability to work after receiving combination antiretroviral therapy (cART). We aimed to investigate predictors of regaining full ability to work at 1 year after starting cART. Methods.  Antiretroviral-naive HIV-infected...
