Targeting IGF1‐Induced Cellular Senescence to Rejuvenate Hair Follicle Aging

Aging Cell, EarlyView.
Age‐related increases in IGF‐1 expression in the skin accelerate stem cell exhaustion and senescence by impairing SIRT1 function, ultimately driving hair follicle aging. Conversely, activating SIRT1, clearing senescent cells, or adopting dietary restriction can mitigate excessive IGF‐1 signaling and provide a promising strategy to rejuvenate hair ...

Prevention of Post‐Inflammatory Hyperpigmentation in Skin of Colour: A Systematic Review

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background/Objectives Post‐inflammatory hyperpigmentation (PIH) impacts all skin tones with a heightened predilection for Fitzpatrick skin types (FST) III‐VI. Preventative measures include pre‐ and post‐intervention approaches, such as sunscreen and corticosteroids. This systematic review aims to summarise the preventative measure outcomes for

Two‐year changes of macular choroidal thickness in response to 0.01% atropine eye drops: Results from the myopia outcome study of atropine in children (MOSAIC) clinical trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate 2‐year changes in macular choroidal thickness (ChT) in children receiving 0.01% atropine eyedrops and its relationship with spherical equivalent refraction (SER) progression and axial length (AL) elongation. Methods A total of 250 myopic children aged 6–16 years (167%–0.01% atropine, 83‐placebo) were enrolled in the ...

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?

Acta Ophthalmologica, EarlyView.
Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.
