In this study, researchers developed a method for high-resolution live imaging of leg regeneration in the crustacean Parhyale hawaiensis, which effectively captures the entire process at cellular resolution over 10 days while minimizing photodamage.

This study analyzed dosimetric quantities in x-ray microbeam radiation therapy and found that the peak-to-valley dose ratio decreases with depth in the irradiated object.

This study found that polarized light microscopy is more effective than diffractive microscopy in distinguishing scarring from non-scarring alopecia, providing a highly specific adjunct diagnostic tool for alopecia biopsy specimens.

This study used infrared spectral imaging to show for the first time the distribution of glypican-4 and glypican-6 in hair follicles across different growth phases, highlighting the potential of this technique for studying alopecia.

This study observed that CT imaging is essential for evaluating posterior column injuries in patients with tibial plateau fractures, finding a 26.7% occurrence rate in the posterolateral column and 25.7% in the posteromedial column, aiding in accurate intervention planning.

This study found that hair damage from sunlight and chemical processes like perms and bleaching varies in internal microstructure changes, suggesting that protective techniques should be tailored to the type of chemical treatment used.

This study developed a universal ballistic trajectory model for unguided projectiles that considers both aerodynamics and altitude effects, showing comparable results to existing trajectory models and radar measurements.

This study compared the diagnostic effectiveness of Folliscope and Trichoscope in 100 men with androgenetic alopecia, concluding that using both methods enhances diagnostic accuracy by providing complementary insights—Trichoscope highlights patterns while Folliscope offers objective measurements.

A simple method can show hair's surface pattern.

This study found that integrating machine learning enhances the predictive accuracy of forensic DNA phenotyping from low template DNA, achieving high accuracy for traits like eye color, although challenges remain for admixed populations and complex traits.
