RESULTS: Both groups showed a significant change in Investigator Assessed Overall Hyperpigmentation and Investigator Assessed Overall Photodamage over time (P<0. Both groups resulted in significant reduction of hyperpigmentation and photodamage.
Relevant if you're working with retinol, collagen for aging and hyperpigmentation.
If you're targeting aging, this research supports adding retinol to your PM routine. Effective concentration range: 0.05% based on this study. Timeline to expect: 4 weeks based on study duration.
If you're targeting aging, this research supports adding collagen to your AM/PM routine. Effective concentration range: 0.05% based on this study. Timeline to expect: 4 weeks based on study duration.

Single-Center, Prospective, Double-Blind, Evaluator-Blind, non-Randomized, Vehicle-Controlled Trial With a 1927 Nm Non-Ablative Fractionated Laser and Topical 0.05% Tretinoin Lotion for Facial Dyspigmentation and Photodamage. Almukhtar R, Carr E, Angra K, Lipp M, Boesn M, Goldman M. BACKGROUND: Dyspigmentation and photodamage are common concerns in patients who seek aesthetic consultation. A number of treatment modalities have been utilized to address this issue. 1927 nm thulium fiber laser is a fractionated non-ablative laser that has been shown to be safe and effective in treatment of photoaging. Topical retinoids have been used for over two decades for photoaging to promote epidermal hyperplasia and collagen synthesis and to decrease melanin production. There has been lack of data to support the combination of topical retinoids with laser treatments in the management of facial dyspigmentation and photodamage. OBJECTIVE: The primary objective of this study is to evaluate the benefits and subject satisfaction resulting from use of a 1927 nm thulium fiber laser with and without 0.05% tretinoin lotion for facial dyspigmentation and photodamage. RESULTS: Both groups showed a significant change in Investigator Assessed Overall Hyperpigmentation and Investigator Assessed Overall Photodamage over time (P<0.001). No statistically significant differences were seen between groups at any time point as measured by investigator reported and subject reported efficacy scales except for Subject Global Aesthetic Improvement Scale and Subject Satisfaction at 30 days after laser treatment, at which patients who received 0.05% tretinoin lotion reported a lower level of improvement (2.8 ± 0.86 in the treatment group vs 2 ± 0.85 in the vehicle group, P=0.009) and lower patient satisfaction when compared to the vehicle group (2.87 ± 1.55 in the treatment groups vs 1.53 ± 0.64 in the vehicle group, P=0.001). CONCLUSION: In our study, patients tolerated the combination of 1927 nm thulium fiber laser and 0.05% tretinoin lotion well. Both groups resulted in significant reduction of hyperpigmentation and photodamage. Subject satisfaction and perceived improvement were temporarily lower at 30 days only when, combining 0.05% tretinoin lotion with 1927 nm thulium fiber laser. Future studies are needed to investigate the impact on efficacy when combining laser procedures with a longer duration of use or a higher concentration of topical tretinoin.

Original source →Friedreich's ataxia is a rare, chronic, progressive, neurodegenerative condition affecting multiple organ systems, including neurological, musculoskeletal, cardiac, and endocrine systems, and is marked by low cardiopulmonary fitness. We tested the effect of exercise and NAD+ precursor supplementation with nicotinamide riboside, which have each shown benefits in animal and early clinical studies, on cardiopulmonary fitness in individuals with Friedreich's ataxia. This 12-week, outpatient, phase 2, single-site (Children's Hospital of Philadelphia, Philadelphia, PA, USA), randomised, 2 × 2 factorial clinical trial recruited individuals aged 10-40 years with an ejection fraction of 45% or greater who were able to exercise.
Wounds continue to represent a significant public health challenge globally. In recent years, Astragalus mongholicus Bunge, a traditional Chinese botanical drug utilized for wound treatment, has garnered increasing research attention. However, the therapeutic efficacy and safety of this natural botanical drug on wound healing remain poorly understood.
Recent preclinical studies have shown that nicotinamide adenine dinucleotide (NAD+) plays a critical role in molecular mechanisms of axon degeneration, and reductions in NAD+ levels are associated with axonal degeneration. Nicotinamide riboside (NR) is a safe and widely available pyridine-nucleoside form of vitamin B3 and is an NAD+ precursor. To investigate if oral supplementation of synthetic NR can act as a therapeutic agent to prevent degeneration of small somatic sensory axons innervating the skin or promote regeneration of these same fibers in humans, we utilized a validated experimental model of cutaneous nerve degeneration and regeneration and conducted a placebo-controlled, double-blinded Phase 2 study.
