In this study, Nd:YAG picosecond lasers using fractional micro-lens array were found to have a comparable effect to ablative fractional Er:YAG lasers in treating atrophic acne scars, with better safety profiles but slightly less patient satisfaction.

This study found that inhibiting DPP4 during a critical period post-wounding increases hair follicle regeneration and Wnt signaling in large skin wounds.

This article reviews applications of optical coherence tomography techniques in medicine, including for diagnosing androgenic alopecia and monitoring blood coagulation, but provides no new clinical results.

This study used phase contrast hard x-ray microscopy to capture detailed images of healthy human hair, revealing distinct structures such as the medulla, cortex, and cuticular layer.

This article discusses how DNA-based phenotyping is used by police to create visual profiles of suspects from crime scene samples, but reports no new research findings.

This study found that Tianqi trichogen promoted hair growth in tested animals, with no observed photoallergic reactions or significant skin allergies.

This study identified a new gene, mrp4, in mice, which suggests it may have a unique role in the growth and development of hair follicles in the ears and tails.

In this report, a 19-year-old Japanese man experienced severe and prolonged urticarial reactions following treatment with diphenylcyclopropenone for alopecia universalis, emphasizing the need for caution with potent sensitizers.

This study found that Rumex japonicus Houtt. root extract promoted hair growth by enhancing cell proliferation and preventing apoptosis in human dermal papilla cells and HaCaT cells, as well as in a mouse model.

This study found that UVB exposure led to visible tanning and distinct DNA methylation changes in pigmentation genes in tan-capable skin but not in non-tan skin, highlighting GNAS as a potentially UVB-responsive gene.

This study found that proton minibeam radiotherapy demonstrated a potential tissue-sparing effect in epidermis models by spatially confining DNA damage, suggesting reduced side effects in radiotherapy.

New method quickly and accurately measures dexpanthenol in hair products.

This report describes a case where solar-induced postinflammatory hyperpigmentation following laser hair removal was treated with a combination of topical treatments and serial TCA peels, resulting in only slight improvement.

A medication may help with hair growth in psoriasis, and a skin condition might be linked to a specific bacteria.

This study found that Pik3r1 Y657* mice, which model human SHORT syndrome, show increased energy expenditure despite insulin resistance, but this is not due to changes in locomotion, thermoregulation, or Ucp1-dependent thermogenesis, suggesting a different metabolic mechanism may protect against lipotoxicity.

In this study, I-PRF, a blood-derived biomaterial without anticoagulants, was found to inhibit melanin production and reduce oxidative stress damage in a rat model of melasma, suggesting it as a safe and cost-effective treatment option.

Hhip-Cre effectively targets dermal papilla cells for gene manipulation in hair biology.

This piece reflects on the past year of editing the Assistants' Corner and presents no new research findings.

This study identifies the PI4P-RHD4 module as a key regulator of GET pathway receptor dynamics in Arabidopsis, affecting TA protein insertion and root hair growth.

This study identified ISPP-Rb, a novel immuno-stimulatory complex from Royoporus badius, that significantly activates murine macrophage cells and induces multiple proinflammatory cytokines.

This study found that melanin extracted from cuttlefish ink provided significant protection against UV radiation damage to human hair, suggesting its potential as a photoprotective agent in hair-care products.

This study suggests that the transcription factors SP1 and KROX20 regulate CUX1 gene's effect on the proliferation of ovine dermal papilla cells in vitro.

This study concluded that intense pulsed light treatment effectively thinned hair to achieve a natural look after hairline correction surgery in East Asian women with naturally thick hair.

VIP reduces hair pigmentation by decreasing melanin production.

This retrospective study reported significant improvements in keloid scars among 60 patients treated with punch excision and superficial X-ray, with lower Vancouver Scar Scale and Patient and Observer Scar Assessment Scale scores a year post-treatment and no severe adverse reactions observed.

This study found an IFIS incidence rate of 3.18% among cataract surgeries in a Chinese hospital and identified reserpine, clozapine, and post-panretinal photocoagulation as new risk factors.

In this animal study, topical pentoxifylline was associated with improved hair regrowth in cyclophosphamide-induced hair loss in male Swiss albino rats.

This review discusses the regenerative potential of polynucleotides and polydeoxyribonucleotides in aesthetic medicine, noting their benefits for skin texture, hydration, and patient satisfaction despite limited high-quality evidence.
