This case report describes the first confirmed instance of trichodysplasia spinulosa in a child with Down syndrome and leukemia, linking it to the TS-associated polyomavirus.

This study observed that undifferentiated matrix cells at the base of the hair follicle differentiate into the medulla, cortex, cuticle, and inner root sheath cell types through specific morphological changes.

This study examined the morphological variations of terminal hair from different body regions of a Caucasian male, finding notable differences in diameter and features like "steak-boning" in specific hair types.

This review examines physical methods like electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry, highlighting their complementary capabilities in analyzing biomolecular structures and mycobacterial interactions with reactive oxygen species and antioxidants.

This study investigated the hair structure of wild pigs in the Balıkesir region using stereomicroscopy and scanning electron microscopy, finding distinct bifurcation patterns, but concluded that pig bristles used in brushes likely wouldn't retain these features, complicating species identification.

This study observed that hairless mice of different strains initially grow hair but soon develop alopecia and other skin and pigmentation changes with age.

This study suggests that holes found in mature hair fibers may be linked to daily hair care actions and the removal of extractable substances.

In this study, an 11-year-old girl with acrodermatitis enteropathica showed significant improvement in symptoms after oral zinc therapy.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

This study found that bimatoprost eye drops increased eyelash length, thickness, pigmentation, and the number of eyelashes per follicle in rabbits, without causing inflammation.

This study found that bimatoprost eye drops significantly increased eyelash length, thickness, pigmentation, and the number of eyelashes per follicle in rabbits within one month.

In this case report, an 11-year-old girl with acrodermatitis enteropathica experienced a complete resolution of symptoms following oral zinc therapy, highlighting its effectiveness in managing this condition.

In this study, researchers found that progesterone promotes breast tumor growth in mice through its metabolite 5αP, which can be blocked by the 5α-reductase inhibitor finasteride.

In this study, eight healthy dogs showed hair and skin damage, including hair shaft fractures and skin irritation, after repeated application of Clairol Hair Dye Flaxen Blonde.

This study observed that individuals with type 1 diabetes mellitus have notably lower levels of essential and trace elements like Calcium, Potassium, and Zinc in biological samples compared to non-diabetic controls.

In this animal study, researchers observed that both aging and lower androgen levels in male albino rats led to significant structural changes in meibomian glands, including reduced acinar cell size, diminished meibum secretion, and increased collagen deposition.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This study found that nanoparticles can penetrate the skin, but artifacts produced during specimen preparation complicate accurate observation, and proposed a method for reducing errors in imaging quantum dots as tracers.

This study observed that epidermal necrosis and keratinocytic ballooning are consistent histopathologic signs of monkeypox in skin lesions, reinforcing the diagnostic value of histopathologic and immunohistochemical analyses.

This case report describes a giant pigmented tumor of the scalp in a 47-year-old woman and suggests a possible dual origin involving neural crest differentiation.

This study found that the switch-off of melanogenesis during the hair cycle in C57 BL-6 mice is a gradual and stochastic process starting in mid anagen VI, with specific biochemical markers indicating the transition to catagen.

This study observed that particles sized 300-600 nm penetrate hair follicles more efficiently, likely due to alignment with the thickness of the human hair cuticula.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

This case report describes the characteristic clinicopathological features of trichodysplasia spinulosa in two boys with acute lymphocytic leukemia, highlighting its resolution as immune function normalizes.
