Optical Urea Sensing in Sweat for Kidney Healthcare by Sensitive and Selective Non-enhanced Raman Spectroscopy

Christian Enz, Sandro Carrara, Assim Boukhayma, Ata Jedari Golparvar, Mattia Petrelli

Sweat biomarker analysis has attracted much interest in applications ranging from sports to wearable healthcare. Among all the sweat biomolecules, abnormal urea levels have been linked to several complications, particularly renal dysfunction. Here, we repo ...

Neurometabolic profiles of bile duct ligated rats after the treatment with an urease inhibitor – 1H MRS dataset

Cristina Ramona Cudalbu, Dunja Simicic

1H MRS in the cerebellum was used to study the effect of 2-octynohydroxamic acid (2-octynoHA) treatment on the brain of bile duct ligated (BDL) rats (type C hepatic encephalopathy). The study included four groups of rats: negative control group (rats recei ...

Urea Derivative-Promoted CsPbl(2)Br Perovskite Solar Cells with High Open-Circuit Voltage

Yang Liu, Bowen Yang, Chen Li, Xin Guo

Inorganic perovskite solar cells (PSCs) have witnessed extraordinary advances owing to their prominent stability against thermal aging. However, they suffer from a phase transition from black phase to yellow phase under ambient conditions and serious energ ...

High-resolution cryo-EM structure of urease from the pathogen Yersinia enterocolitica

Henning Paul-Julius Stahlberg, Jasenko Zivanov

Urease converts urea into ammonia and carbon dioxide and makes urea available as a nitrogen source for all forms of life except animals. In human bacterial pathogens, ureases also aid in the invasion of acidic environments such as the stomach by raising th ...

Effect of Chaotropes on the Transfer of Ions and Dyes across the Liquid–Liquid Interface

Hubert Girault, Pekka Eero Peljo, Evgeny Smirnov, Grégoire Clément Gschwend, Lucie Josette Renée Rivier, Elena Vladimirova

Chaotropes such as urea can break the structure of water, weakening the hydrophobic effect and reducing aggregation. Here, we investigated how the addition of urea affects the transfer of ions and cationic dyes across the interface between immiscible elect ...

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 ...

Forcing the "lazy" protons to work

Jayasubba Reddy Yarava

The combination of cross-polarization (CP) with flip-back (FB) pulse has enabled in NMR the enhancement of C-13 sensitivity and the decrease of the recycling delay at both moderate and fast magic-angle spinning (MAS) frequencies. However, only continuous-w ...

Use of VacA as a Vaccine Antigen

Dominique Velin, Mati André Marie Moyat

One of the major toxins secreted by H. pylori is the Vacuolating cytotoxin A (VacA) named after its ability to induce the formation of "vacuole"-like membrane vesicles in the cytoplasm of gastric cells. VacA has been associated with the disruption of mitoc ...
