Characteristics of Salivary Iodine Concentration in Elderly Residents of High-iodine Areas.

Salivary iodine is considered a potential indicator for assessing iodine nutrition status. However, there is currently a lack of research data on the characteristics of salivary iodine concentration (SIC) in the elderly population. To evaluate the characteristics of SIC and assess its efficacy in diagnosing thyroid disorders among the elderly population, a cross-sectional study was conducted in a high-iodine area.

Reconstruction of a complex-valued object without a support constraint.

This study demonstrates that a nonnegative complex-valued object without support constraints can be reconstructed from its diffraction pattern, even with partially missing data. We employed a continuous hybrid input-output (CHIO) algorithm, which imposes double nonnegative constraints on the real and imaginary parts of the object. The missing data at the diffraction pattern center is recovered linearly before iterations.

A Plasmonic Nanoledge Array Sensor for Selective Detection of Cardiovascular Disease Biomarkers in Human Whole Blood.

Optical sensors face challenges when detecting ultralow amounts of analytes in whole blood, including signal quenching due to optical absorption and false positives due to nonspecific binding. This study introduces gold nanoscale array features termed nanoledges (NLs), which interact with incident white light to produce a transmitted surface plasmon resonance (tSPR) signal. This extraordinary optical transmission (EOT) spectrum occurs in the near-infrared (NIR) region, thereby minimizing signal quenching caused by visible-light absorption from blood proteins and pigments.

Drug-eluting contact lenses: Progress, challenges, and prospects.

Topical ophthalmic solutions (eye drops) are becoming increasingly popular in treating and preventing ocular diseases for their safety, noninvasiveness, and ease of handling. However, the static and dynamic barriers of eyes cause the extremely low bioavailability (<5%) of eye drops, making ocular therapy challenging. Thus, drug-eluting corneal contact lenses (DECLs) have been intensively investigated as a drug delivery device for their attractive properties, such as sustained drug release and improved bioavailability.
