Impaired synthesis of DHA in patients with X-linked retinitis pigmentosa
Journal of Lipid Research, 2001 Many patients with X-linked retinitis pigmentosa (XLRP) have lower than normal blood levels of the long-chain polyunsaturated ω3 fatty acid docosahexaenoic acid (DHA; 22:6 ω3).

Consensus recommendations for hyperpolarized [1‐13C] pyruvate MRI multi‐center human studies
MRI of hyperpolarized (HP) [1-13C]pyruvate allows in vivo assessment of metabolism and has translated into human studies across diseases at 15 centers worldwide. To determine consensus on best practice for multi-center studies for development of clinical

Advanced Materials, EarlyView.A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

Advanced Materials, EarlyView.We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Bridging Biosensing and Hardware‐Level Data Security With a Conjugated Radical Polymer
Advanced Materials, EarlyView.A conjugated radical polymer provides two complementary functions within a common material platform: sensitive dopamine biosensing and device‐specific stochastic electrical responses for security. The work demonstrates a materials‐based approach for combining bioelectronic signal acquisition with hardware‐level authentication while maintaining the ...

Three-Dimensional 13C-13C-Correlated Experiments on Oligosaccharides
Journal of Magnetic Resonance, Series B, 1993 Abstract The use of three-dimensional 1H-detected 13C-13C-correlated experiments is demonstrated for the purpose of assigning all of the ring proton and carbon resonances from a digalactosyl diacylglyceride sample, uniformly 13C-enriched to 15% by microbiological methods. In addition to improving the previously published phase-cycled pulse sequences (
