Probing renal pH using hyperpolarized [1-13C]alaninamide
Rolf Gruetter, Arnaud Comment, Hikari Ananda Infinity Yoshihara, Alice Radaelli
Hyperpolarized molecular probes can be effectively used as pH markers. To date, the only two probes reported in vivo as extracellular pH sensors are 13C-bicarbonate, and [1,5-13C2]zymonic acid. Alaninamide is a derivative of alanine which is found to be se ...
2018Towards a point-of-care nanoplasmonic biosensor for rapid and multiplexed detection of pathogenic infections
Hatice Altug, Xiaokang Li, Filiz Yesilköy, Alexander Belushkin, Maria Soler Aznar
The implementation of multiplexed point-of-care biosensors is a top priority to address the current epidemic problems originated by widespread pathogenic infections, like those caused by viruses or bacteria. A rapid and accurate detection, identification, ...
SPIE-INT SOC OPTICAL ENGINEERING2018Multiplexed nanoplasmonic biosensor for one-step simultaneous detection of Chlamydia trachomatis and Neisseria gonorrhoeae in urine
Hatice Altug, Andrea Cavallini, Alexander Belushkin, Maria Soler Aznar
Development of rapid and multiplexed diagnostic tools is a top priority to address the current epidemic problem of sexually transmitted diseases. Here we introduce a novel nanoplasmonic biosensor for simultaneous detection of the two most common bacterial ...
2017Identification of the inactivating factors and mechanisms exerted on MS2 coliphage in concentrated synthetic urine
Volume reduction (condensation) is a key for the practical usage of human urine as a fertilizer because it enables the saving of storage space and the reduction of transportation cost. However, concentrated urine may carry infectious disease risks resultin ...
Elsevier2017Towards sustainable sanitation: Identifying and mitigating microbial health risks in the production of urine-derived fertilizers
Tamar Kohn, Simon Schindelholz, Timothy R. Julian
Sanitation systems that systematically recover and reuse waste can promote social enterprise, reduce discharge of harmful nutrients, pathogens and other contaminants to the environment, replace synthetic fertilizer sources, and increase access to sanitatio ...
2017Reaction extents: A Divide-and-Conquer Approach for Kinetic Model Identification
Dominique Bonvin, Julien Léo Billeter
Obtaining reliable wastewater treatment process models is critical for the application of model-based design, operation, and automation. For example, Masic et al. (2014) explored the use of an observer designed for nonlinear processes to estimate nitrite i ...
2017Solar photo-Fenton and UV/H2O2 processes against the antidepressant Venlafaxine in urban wastewaters and human urine. Intermediates formation and biodegradability assessment
Hubert Girault, César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Stefanos Giannakis, Milica Jovic, Idriss Hendaoui
In this work, the use of Advanced Oxidation Processes (AOPs) against the degradation of an emerging contaminant has been subjected under systematic investigation. The optimization of treatment of the anti- depressant drug Venlafaxine (VFA) was performed, u ...
Elsevier Science Sa2017Quantifying microbial risks of field-scale struvite production from source-separated urine using first-person videography exposure assessment
Tamar Kohn, Ana Karina Pitol Garcia, Timothy R. Julian
This paper quantifies occupational exposures to pathogens in urine during urine collection and processing into fertilizer as well as attendant risks of infection from indirect pathogen exposure. We also detail the microlevel activity time series (MLATS) me ...
2016Hygiene considerations during the collection, storage and processing of source-separated urine into a marketable fertilizer
Tamar Kohn, Simon Schindelholz, Manfred Schoger
Laboratory and field studies along with inactivation data from the literature are used to model bacteria inactivation during urine storage and struvite production. The model is used to evaluate urine storage and struvite drying under the fluctuating temper ...
2016Bacteria inactivation during the drying of struvite fertilizers produced from stored urine
Tamar Kohn, Loïc Decrey, Simon Schindelholz, Manfred Schoger, Kai Udert
Human urine can be processed into market-attractive fertilizers like struvite; however, concerns regarding the microbial safety of such products remain. The present study evaluated the inactivation of in situ heterotrophs, total bacteria as observed by flo ...
