This case study found that a 7-year-old girl's crystalline cataract had sulfur-containing amino acids likely cystine, and was associated with abnormal hair conditions.

This study reported that using photomnemonics facilitated accurate histopathologic interpretation of horizontal scalp sections in distinguishing between nonscarring and scarring alopecias by dermatopathologists and residents in a validation test.

This study found that crossbred lambs fed liquid diets with reconstituted cow's milk initially grew wool without crimp, with crimp resuming two weeks post-weaning.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This study found that knocking down P-cadherin expression in cultured human hair follicles recreates the hair abnormalities seen in patients with hypotrichosis with juvenile macular dystrophy.

Trichoscopy is a helpful and quick method to diagnose hair loss without shaving.

This study developed a multifunctional bilayer dressing containing nanosilver and basic fibroblast growth factor, which improved wound healing by preventing bacterial penetration, promoting angiogenesis and hemostasis, and accelerating cell proliferation and migration, outperforming a control group by increasing healing rates by 47% in vivo.

This case report describes the first known instance of loose anagen hair syndrome in a Southeast Asian child, a 13-year-old Thai boy with hair thinning and excessive shedding on the frontal scalp.

This review discusses the basic principles of hair pathology and findings in common types of alopecia but reports no new research results.
