This study suggests that basonuclin may act as a tissue-specific transcription factor for ribosomal RNA genes by interacting with the promoter region necessary for high transcription levels in human keratinocytes.

This study identified 65 bacterial species from human hair with varying carbon metabolic capabilities and proposed a systematic way to evaluate their ease of isolation under different conditions.

The researchers observed that two non-antimicrobial shampoos caused a significant increase in fungal germs but did not affect the overall scalp microbiota diversity over two weeks, suggesting these formulations may preserve or stimulate the scalp microbiota without adverse effects.

In this study, the researchers found that a 28-day topical treatment with a postbiotic ferment complex notably altered the scalp microbiome in women with sensitive scalps, increasing certain bacterial species and decreasing others, while also reportedly alleviating symptoms of sensitive skin syndrome in all participants.

The study emphasizes that telomere shortening is identified as the sole cause of aging among the twelve hallmarks and suggests that increasing telomere and rDNA array length in adult stem cells might effectively reverse aging and extend lifespan.
