Spatially Informed Feature Selection and Machine Learning in Matrix‐Assisted Laser Desorption/Ionization Imaging for Cohort‐Scale Molecular Tissue Phenomics in Glioblastoma

Advanced Intelligent Discovery, EarlyView.
Matrix‐assisted laser desorption/ionization imaging‐based identification of reliable small molecule markers across heterogeneous glioblastoma cohorts is challenging with intensity‐only methods. We present spatially informed feature selection (SIFS), a spatially informed framework that prioritizes molecules consistently colocalizing with histopathology.

Fluorescent Hydrogel‐Based Strain Sensor With Machine Learning‐Augmented Performance

Advanced Intelligent Discovery, EarlyView.
Fluorescent hydrogel strain sensor based on carbon quantum dots enabling optical readout of deformation through strain‐dependent emission changes, coupled with Random Forest analysis to capture nonlinear fluorescence‐concentration relationships and identify optimal sensing conditions. Hydrogels are ideal matrices for bio‐integrated wearable sensors due

Artificial Eyes and Tear Measurements

Ophthalmology, 1980
Ninety-four consecutive persons with unilateral enucleations or eviscerations were tested by the Schirmer I and Schirmer II tests for tear production. The findings on the artificial eye were compared with those on the companion, living (control) eye. The collected data were subjected to statistical analysis.

Rheological Behavior Patterns in Artificial Tears

Optometry and Vision Science, 2022
SIGNIFICANCE Rheological patterns were objectively calculated considering the first and last viscosity, besides the difference of viscosity with a specific shear rate. Shear thinning, shear thickening, thixotropic, and Newtonian behavior patterns were found.

Classification of Artificial Tears

1998
Natural tears serve three main functions: they maintain the metabolism of the ocular surface tissues, afford a smooth surface that allows regular light refraction, and lubricate the ocular surface to facilitate blinking. They also have other functions, such as specific and non-specific antimicrobial and buffer effects, etc. Natural tears have a complex

Toxic preservatives in artificial tears

Ugeskrift for Læger
Dry eye disease (DED) is a common condition, especially among the elderly. Artificial tears are formulated to relieve the symptoms of DED. However, selecting the most suitable option can be challenging, as the products differ in various aspects, including eligibility for reimbursement, pricing, packaging formats, composition, and presence of ...
