In this study, silencing BMAL1 and PER1 genes increased melanogenic activity in follicular and epidermal melanocytes, suggesting that peripheral circadian clocks may regulate melanin pigmentation.

This article explores the concept of cycling synergistic nutrients to minimize overdose risks and enhance nutrient absorption, but presents no new clinical findings; it suggests applicability across various health domains.

This pilot study found that night shift workers showed fewer signs of wrinkle formation compared to day workers, but there were no significant differences in DNA amplification or collagen percentage.

This study found that extracting RNA from equine hair follicles can effectively identify 24-hour oscillations of specific circadian clock genes, offering a valuable non-invasive method to evaluate the equine circadian clock.

This review discusses recent evidence on how night-shift work affects the circadian system, sleep, and alertness in shift workers, and reports no clinical results; potential impacts on health are considered.

This study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.

In this case report, a patient with Cronkhite-Canada Syndrome developed colon cancer and liver metastasis despite hormone therapy, highlighting the need for regular monitoring and early detection strategies.

The new method can measure sleep-related hormones in hair effectively and could help track long-term sleep patterns.

This case report describes a 60-year-old woman with Cronkhite-Canada syndrome whose symptoms and polyposis improved following prednisolone therapy, but emphasizes the need for periodic digestive tract screening due to associated cancer risks.

In this study, bright light exposure during the daytime did not significantly affect clock gene expression in humans, although Rev-erb-ß expression appeared stronger under bright light compared to dim light.

In this case report, a 72-year-old female with Cronkhite-Canada syndrome showed significant improvement in symptoms and gastrointestinal polyps after hormone therapy and additional treatment.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This article discusses the challenges in evaluating drug effects on hair growth and emphasizes DNA-flowcytometry as a reliable method for this purpose, without reporting new clinical results.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

In this study, cancer patients aged 30 to 50 reported experiencing diagnostic delays, coping through self-advocacy, and facing stigma-related challenges such as alopecia. The authors concluded that improved physician awareness, tailored screening, and addressing stigma are essential for enhancing care for early-onset colorectal cancer patients.

This case report from Qatar highlights the failure of traditional diagnostic approaches in a young woman with severe hair loss, emphasizing the potential benefits of DNA-guided nutrigenomics and the importance of compassionate communication in addressing psychosocial distress.

This pilot study suggests that topical melatonin may protect hair follicle stem cells from paclitaxel-induced damage, potentially preventing chemotherapy-induced alopecia and enhancing the effects of scalp cooling caps.

In this case study, administration of prednisolone and Bactrim for a woman with Cronkhite-Canada syndrome led to the cessation of diarrhea, increased serum protein, and improvement in hyperpigmentation and hair regrowth.

This study found that clipping is the most effective method for anagen synchronization in adult rat models to mimic chemotherapy-induced alopecia, producing robust anagen phases without causing skin trauma.

In this pilot study, researchers found that ex vivo treatment with topical melatonin reduced chemotherapy-induced apoptosis and DNA damage in hair follicle stem cells of human scalp cultures, suggesting melatonin's potential as a protective agent against taxane-induced permanent hair loss.

This source redefines anti-aging medicine as "precision healthspan pharmacology," suggesting that rather than just treating diseases or accepting aging, pharmacology should focus on expanding functional capacity across various health domains, while emphasizing the importance of fundamental physiological and psychosocial health factors.

This narrative review highlights the critical role of intracrine hormone production in peripheral tissues, suggesting that continuous-release subcutaneous testosterone pellet therapy may offer a more effective symptom-driven approach for aging populations, though large-scale randomized controlled trials are needed for confirmation.

This study found that cold exposure disrupts the circadian rhythm in cultured human cells by reducing oscillation amplitude, which is restored upon rewarming, while human hair follicle cells showed minimal amplitude sensitivity to temperature changes, suggesting an evolutionary advantage related to Hopf bifurcation dynamics.

This study found that cooling combined with antioxidants can improve scalp cooling effectiveness in preventing chemotherapy-induced alopecia by maintaining hair follicle viability and function.

This study developed a physician-guided algorithm to manage cutaneous adverse events from hormonal therapy in cancer patients, aiming to reduce treatment interruptions and enhance quality of life.

This review discusses the potential of traditional Chinese medicine to relieve clinical symptoms in cases of CCS and emphasizes the need for further large-scale, long-term studies to verify these effects.

This review discusses Cronkhite-Canada syndrome, highlighting a relatively mild case and suggesting that it may be a more benign and possibly reversible condition with treatment, but reports no new clinical results.

This study introduces a mouse model of cyclophosphamide-induced alopecia, which effectively replicates human chemotherapy-induced hair loss and can be pharmacologically manipulated to study hair regrowth patterns.
