In this study, researchers examined two new cases of trichothiodystrophy and observed that the condition is linked to decreased synthesis of high-sulfur matrix proteins in hair.

This review explores how air pollutants may contribute to various skin diseases and highlights potential mechanisms, but it presents no new clinical findings.

In this study, researchers found that trichothiodystrophy hair brittleness is linked to abnormalities in sulfur content and structural organization, making it prone to breakage.

This study suggests that increased amounts of less stable disulfide conformers in hair shafts may be linked to the brittleness observed in trichothiodystrophy.

This paper describes recent advancements in the synthesis of thiasteroids but reports no new experimental results, noting that introducing heteroatoms in steroidal structures has potential biological effects.

This report describes a new case of isolated trichothiodystrophy with characteristic brittle hair and suggests a simplified classification scheme for understanding sulfur-deficient hair disorders.

This study reports that despite normal cystine incorporation into hair follicles, trichothiodystrophy patients have decreased cystine levels in hair shafts, contradicting the hypothesis of defective transport in hair follicles.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study found that trichothiodystrophy can be diagnosed prenatally in the second trimester using an endoscopically-guided fetal eyebrow biopsy, with sulfur content analysis being the most reliable test.

This study found that high exposure to air pollutants like SO2, NO, NO2, NOx, and PM2.5 was linked to a significantly increased risk of developing PCOS in women.

This study demonstrated that using lead-doped keratin film as a calibration standard allows for accurate tracking of lead distribution along hair strands, revealing different exposure patterns among workers in a battery manufacturing factory in Thailand.

This review discusses the evolutionary history of keratins and reports no new results, highlighting key events that contributed to the development of mammalian hair and integument.

In this study, the varied phenotype of trichothiodystrophy was highlighted, with findings of distinctive hair shaft abnormalities and a wide range of multisystem issues, including neurologic and urologic disorders.

This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.

This study found that a patient with giant axonal degeneration had unique hair abnormalities such as trichorrhexis nodosa and altered S:N ratios, unlike her relatives but comparable to unrelated controls.

This study found that electron and proton microprobe analysis can reveal differences in element distribution within human hair and epidermis, although no significant water content differences were noted between atopic eczema and normal skin.

This case report describes a patient with trichothiodystrophy presenting with autism, mental retardation, and seizures, characterized by distinct hair abnormalities under microscopy.

Tiger tail banding and hair abnormalities are reliable indicators for diagnosing trichothiodystrophy.

This study explains that while trichothiodystrophy and xeroderma pigmentosum share genetic defects, TTD patients primarily exhibit issues in transcription initiation, not the increased skin cancer risk seen in XP.

This article discusses silicon in hair loss but provides no new research findings or clinical results.

This review explores the immunological aspects of epidermal differentiation in loricrin knockout mice, offering insights into keratinization and potential intrinsic factors affecting immune function, but provides no new clinical findings.

This review discusses molecular signaling pathways and nutritional factors influencing feather growth and regeneration in poultry and offers no new results; the authors suggest these insights may guide strategies for producing superior plumage.

This study found that the concentrations of major inorganic elements in human scalp hair increase with age up to 25 years, and calcium and magnesium concentrations are significantly associated with sex in individuals over 20.

This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

This study describes a rare form of congenital alopecia in domestic short hair cats, characterized by hair shaft defects and follicular dystrophy similar to those seen in certain mutant mouse strains.

This study measured elemental content in anagen hair fibers of Caucasian people aged 10-69 and found average levels of sulfur, zinc, calcium, and chlorine, establishing a baseline for future research.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This article discusses the history and understanding of Tay syndrome, recognizing it as a distinct condition related to ichthyotic erythroderma, mental retardation, and brittle hair but reports no new clinical results.

Using hair oil/grease may be linked to dandruff in African American girls.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.
