Finger length ratios are not linked to the number of specific gene repeats affecting testosterone sensitivity.

This study found that diffuse and pseudo-fringe sign patterns are common in Asian patients with frontal fibrosing alopecia, and that treatments combining antiandrogens or antimalarials with topical therapy are effective.

This study showed that the zinc finger protein GIS3 is important for root hair growth in Arabidopsis by regulating RHD2 and RHD4 genes, with application of ethylene and cytokinin helping restore root hair presence in mutated variants.

In this study, fingertip regeneration in mice was associated with specific signaling pathways involving hair follicles and hedgehog signaling, with potential implications for improving human hand injury treatments.

This study reports that a lower 2D:4D finger length ratio is significantly associated with higher disease activity and reduced spinal mobility in females with ankylosing spondylitis, but not in males.

This study reviews the role of the zinc finger protein CXXC5 in cellular signaling and its implications for cancer, discussing how its dysregulation is linked to various physiological and pathological processes, as well as potential therapies targeting CXXC5.

This study highlights the use of hair and fingernail cortisol levels as retrospective indicators of chronic stress, particularly in minoritized populations facing social stressors that increase the risk of mental health issues.

In this study, researchers found that mouse digits without nails could not regenerate after amputation, highlighting the necessity of nails for fingertip regeneration and suggesting a potential role for the Lmx1b gene in this process.

This case report highlights a rare instance of fingernail and toenail hyperpigmentation following the use of valproic acid, which resolved after discontinuation of the drug.

In this study, Flii overexpression in mice enhanced fingertip regeneration and nail formation after both distal and proximal amputations, suggesting a role in digit and hair follicle regeneration possibly involving Wnt signaling.

This case report describes a 75-year-old carpenter with unexplained weight loss, fingernail loss, and discoloration of the palms and soles, whose diagnostic investigations revealed hypertrophic pangastritis and enteritis.

In this study, researchers found that none of the participants were color blind and reported varying lengths of index and ring fingers among them, exploring a possible link between these finger length ratios and sex-influenced gene expression.

This study found that all five toxic microelements analyzed were most prevalent in the Caspian thin-fingered gecko's bone and muscle tissues, suggesting their tolerance to these elements in polluted areas.

This study found that self-reported androgen-driven phenotypes, like balding and finger length ratios, were not associated with cancer aggressiveness or biochemical recurrence in prostate cancer after prostatectomy.

This article introduces a novel, inexpensive hair preparation technique using glove-finger sheaths to secure and protect hair during calvarial surgery, reducing procedure time and hair damage without the need for full scalp shaving.

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.

This study reported that toxic shock syndrome, originally noted in children, is now predominantly associated with menstruating women, with some experiencing recurrence and complications like vocal cord paralysis and impaired finger sensation.

In this study, tofacitinib treatment in a male patient with alopecia areata led to significant hair regrowth and improvement in nail dystrophy symptoms, restoring finger function within 10 months.

This study found that after application of a testosterone cream containing 17α-methyltestosterone and testosterone propionate, these compounds could be detected in dried blood spots up to 97 hours post-application, potentially leading to sample contamination during fingertip puncture.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

This study found that rete ridge morphogenesis in mammalian skin is directed by a BMP-dependent developmental program, which is evolutionarily distinct from other known pathways controlling the development of hair follicles, sweat glands, and fingerprint ridges.

In this article, researchers describe a novel FUE device designed to enhance follicular unit excision surgery by minimizing follicular injury and improving ergonomics with features such as Bluetooth functionality, fingertip touch sensors, and automated operation.

In a meta-analysis of 210 hair tourniquet syndrome cases, this study reported that 44.2% involved the penis, 40.4% the toes, and 8.6% fingers, highlighting the condition's potential severity and underreporting, especially in infants and some adults with cognitive impairments.

This case study reports that a heterozygous missense GJA1 mutation, p.Gly138Ser, in a 2-year-old boy with oculodentodigital syndrome primarily resulted in syndactyly, fifth finger hypoplasia, and hypotrichosis, without neurological or craniofacial abnormalities.

In this case report, a 17-year-old male with a specific TRPS1 gene mutation presented with sparse, soft hair, short thumbs and toes, misaligned teeth, and distinctive bone abnormalities in the fingers and toes as observed through X-ray analysis.

This study found that videodermoscopy can help diagnose nailbed psoriasis by revealing distinctive hyponychial capillary patterns, which correlated with disease severity and response to treatment.

This study demonstrated that AIRE-deficient rats exhibit key symptoms of APECED, making them a relevant model for exploring potential treatments.

In this study, fMRI results suggested that mechanical stimulation evoked a stronger prickle sensation comprising both pain and itch on hairy skin compared to glabrous skin.

Suplatast tosilate successfully treated a woman's systemic sclerosis symptoms.

This study found that structural changes in the stroma surrounding hair follicles and skin laxity are associated with the appearance of large pores, regardless of ethnicity or age.
