Blood carotenoid concentration measurement is considered the gold standard for fruit and vegetable (F&V) intake estimation; however, this method is invasive and expensive. Recently, skin carotenoid status (SCS) measured by optical sensors has been evaluated as a promising parameter for F&V intake estimation. In this cross-sectional study, we aimed to validate the utility of resonance Raman spectroscopy (RRS)-assessed SCS as a biomarker of F&V intake in Korean adults. We used data from 108 participants aged 20-69 years who completed SCS measurements, blood collection and 3-d dietary recordings. Serum carotenoid concentrations were quantified using HPLC, and dietary carotenoid and F&V intakes were estimated via 3-d dietary records using a carotenoid database for common Korean foods. The correlations of the SCS with serum carotenoid concentrations, dietary carotenoid intake and F&V intake were examined to assess SCS validity. SCS was positively correlated with total serum carotenoid concentration ( = 0·52, 95 % CI = 0·36, 0·64, < 0·001), serum -carotene concentration ( = 0·60, 95 % CI = 0·47, 0·71, < 0·001), total carotenoid intake ( = 0·20, 95 % CI = 0·01, 0·37, = 0·04), -carotene intake ( = 0·30, 95 % CI = 0·11, 0·46, = 0·002) and F&V intake ( = 0·40, 95 % CI = 0·23, 0·55, < 0·001). These results suggest that SCS can be a valid biomarker of F&V intake in Korean adults.

Background: Fatal familial insomnia (FFI) is a rare autosomal dominant inherited disease and a type of prion diseases. We report a case of fatal familial insomnia (FFI) in a 52-year-old man who was initially misdiagnosed as Alzheimer's disease.
Case Presentation: The patient presented with persistent insomnia as the initial symptom, accompanied by cognitive impairment, autonomic dysfunction, and disorders of voluntary movement.

Polyelectrolyte complex nanoparticles (PECNPs) often fully dissociate into individual polycations (PC) and polyanions (PA) at high salinities. Herein, we introduce a novel type of colloidally stable PECNP in which the PC is cross-linked, in this case branched polyethylenimine (PEI) to limit this dissociation, even in solutions up to 5.2 M NaCl or 5.

Lexical competition between newly acquired and already established representations of written words is considered a marker of word integration into the mental lexicon. To date, studies about the emergence of lexical competition involved mostly artificial training procedures based on overexposure and explicit instructions for memorization. Yet, in real life, novel word encounters occur mostly without explicit learning intent, through reading texts with words appearing rarely.

Background: Radiotherapy with or without concurrent chemotherapy is a standard of care treatment for patients with head and neck squamous cell carcinoma (HNSCC). Upon completion, patients are referred for a post-treatment F-FDG PET/CT (Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography) scan to help guide ongoing management by assessing for the presence or absence of residual or recurrent disease and differentiating this from post-treatment inflammation. To improve objective reporting of response, we developed the Christie score.
