Dent disease is a rare X-linked tubulopathy that is characterized by low-molecular-weight (LMW) proteinuria associated with hypercalciuria, which may lead to nephrolithiasis, nephrocalcinosis, and kidney failure between the 3rd and the 5th decades of life in 30-80% of affected males. The disease is most often associated with various manifestations of proximal tubular dysfunction. Affected individuals may present nephrotic range proteinuria which may be misinterpreted and cause diagnostic delay.

Compared to youth with eating disorders like anorexia nervosa (AN), youth with ARFID tend to be younger and are more likely to be male. We aim to describe sex differences in clinical characteristics of youth hospitalized for medical complications of ARFID and compare their characteristics with youth hospitalized for anorexia nervosa.

This study presents an integrated infrared spectroscopic electronic nose system, a novel device that combines infrared (IR) spectroscopy and electronic nose (eNose) concepts for analyzing volatile organic compounds (VOCs) in exhaled breath. This system was calibrated using relevant gas mixtures and then tested during a feasibility study involving 26 gastric cancer patients and 32 healthy controls using chemometric analyses to distinguish between exhaled breath profiles.

- Metal-organic frameworks (MOFs) are important materials used in various applications like catalysis and gas storage, but their open metal sites often get blocked by solvent molecules, requiring activation to use them effectively.
- Traditional activation methods use high temperatures, which can damage the MOFs, but a new 'gas-flow activation' technique employing inert gases at lower temperatures preserves their structure while effectively removing these solvent molecules.
- This study shows that this method not only works well with a specific MOF (HKUST-1) but is also applicable to other types, offering a safer, more efficient approach for activating MOFs without compromising their integrity.
