Enhanced performance of hexavalent chromium reducing cathodes in the presence of Shewanella oneidensis MR-1 and lactate

, 2013
Biocathodes for the reduction of the highly toxic hexavalent chromium (Cr(VI)) were investigated using Shewanella oneidensis MR-1 (MR-1) as a biocatalyst and performance was assessed in terms of current production and Cr(VI) reduction. Potentiostatically

From biomonitoring studies to lowered occupational exposure limits for hexavalent chromium

Societal Impacts
Occupational exposure to the carcinogen hexavalent chromium [Cr(VI)] occurs during stainless steel production, welding, and chrome plating. Two sister-projects, SafeChrom and SAM-Krom, were initiated in Sweden and Denmark, respectively, to inform ...

Kinetic Study of Cr(VI) Reduction in an Indigenous Mixed Culture of Bacteria in the Presence of As(III)

Chemical Engineering Transactions, 2016
Organic compounds can serve as electron donors during Cr(VI) reduction by live microbial cultures. However, Cr(VI) reduction with concomitant oxidation of metalloids such as arsenic has not been studied.

Speciation of Cr(VI) and Cr(III) in Water Samples by Adsorptive Stripping Voltammetry in the Presence of Pyrogallol Red Applying a Selective Accumulation Potential

International Journal of Electrochemical Science, 2012
An adsorptive stripping voltammetric procedure for the speciation of Cr(VI) and Cr(III) in the presence of pyrogallol red (PGR) is presented. The method is based on the previous reduction of Cr(VI) to Cr(III) at the electrode surface, its complexation ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Characterization of chromium species and distribution during Cr(VI) removal by biochar using confocal micro-X-ray fluorescence redox mapping and X-ray absorption spectroscopy

Environment International, 2020
Biochar is an effective, environmentally sustainable material for removing Cr(VI) from water. Potential removal mechanisms include surface reactions or reactions within the biochar structure with direct bonding of Cr(VI) or reduction of Cr(VI) and ...
