Background/objectives: UV radiation is a primary cause of skin damage and photoaging. β-carotene, a potent antioxidant, aids in mitigating UV-induced oxidative stress and enhancing skin photoprotection. This research aimed to evaluate the efficacy of a nutraceutical product designed to prevent photoaging.
Methods: The product consists of a blend of hemp seed oil and banana ( AA), formulated as a chewable tablet. Healthy male participants aged 35-50 years were enrolled in a randomized, parallel, single-blind, placebo-controlled clinical trial. Participants received either the chewable nutraceutical (five tablets after meals in the morning and evening, equivalent to 8 ± 2 mg/day of β-carotene and 400 mg/day of PUFA) or a chewable placebo for 16 weeks. A total of thirty-six participants successfully completed the entire 16-week study.
Results: Administration of the nutraceutical resulted in a significant reduction ( < 0.05) in UV solar light stimulator-induced erythema on the dorsal skin at week 4, with a mean value of 3.76 ± 0.46 AU, compared to the initial value of 4.88 ± 0.62 AU at week 0. Additionally, serum β-carotene concentration significantly increased from 0.45 ± 0.02 µg/mL at week 0 to 0.61 ± 0.06 µg/mL at week 16 ( < 0.05). Moreover, skin intensity in the sun-exposed arm area also significantly improved at week 16, increasing from 71.33 ± 3.50 at week 0 to 81.80 ± 4.45 ( < 0.05).
Conclusions: The results indicate that the developed nutraceutical may offer effective protection against erythema, making it a promising option for preventing photoaging.

Objectives: Macrophage activation syndrome (MAS) is a severe, life-threatening complication of systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD). The objective of this study was to confirm the adequacy of an emapalumab dosing regimen in relation to interferon-γ (IFNγ) activity by assessing efficacy and safety. The efficacy outcome was MAS remission by week 8, based on clinical and laboratory criteria.

Purpose: To characterize the clinical changes occurring in the initial phase of the orthokeratology (OK) treatment for myopia correction, developing a model of prediction of the refractive changes in such phase.
Methods: Prospective study enrolling 64 eyes of 32 patients (range, 20-40 years) undergoing myopic OK treatment with the reverse geometry contact lens CRT (Paragon Vision Science). Changes in uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), refraction, corneal topography, ocular aberrations, and corneal epithelial thickness were evaluated during the first hour of OK lens wear and after 1 week of OK treatment.

The endosome-associated GTPase Rab5 is a central player in the molecular mechanisms leading to degeneration of basal forebrain cholinergic neurons (BFCN), a long-standing target for drug development. As p38α is a Rab5 activator, we hypothesized that inhibition of this kinase holds potential as an approach to treat diseases associated with BFCN loss. Herein, we report that neflamapimod (oral small molecule p38α inhibitor) reduces Rab5 activity, reverses endosomal pathology, and restores the numbers and morphology of BFCNs in a mouse model that develops BFCN degeneration.

Gasoline exposure has been widely reported in the literature as being toxic to human health. However, the exact underlying molecular mechanisms triggered by its inhalation have not been thoroughly investigated. We herein present a model of sub-chronic, static gasoline vapor inhalation in adult female C57BL/6 mice.
