Retinaldehyde is one of the major members of the retinoid family, which has potential skin rejuvenating effects on photoaged skin and has a good safety profile.
The study aimed to evaluate the efficacy and safety of multilamellar vesicle containing retinaldehyde (MLV-RAL) 0.05% and 0.1% used to treat photoaged skin.
A randomized, prospective, investigator-blinded, split-face comparison study was conducted. We enrolled 23 Korean volunteers who applied MLV-RAL 0.05%/0.1% cream on one randomized side of their face and retinol 0.05%/0.1% cream on the opposite side. Wrinkle depth on both crow's feet was assessed by the Antera 3D system. Skin hydration, elasticity, facial curved length, and dermal density were also evaluated.
After an 8-week application, all objective parameters, including wrinkle depth, were significantly improved in both MLV-RAL 0.05%/0.1% and retinol 0.05%/0.1% treated sides. Compared with the retinol-treated side, MLV-RAL-treated side showed a significant improvement of objective assessments except for dermal density. Additionally, there was no adverse event associated with the use of either MLV-RAL 0.05%/0.1% or retinol 0.05%/0.1% cream.
The application of MLV-RAL 0.05%/0.1% cream improved wrinkle, facial contour, and biophysical parameters associated with skin aging.

When a defect occurs in the sanitary plumbing system that affects the system integrity, a cross-transmission route is created that can enable the emission of bioaerosols from the system into the building. These emission occurrences are characterized as short-burst events (typically 11 μm anywhere in the system. Particle count was influenced by toilet flush volume, but it was not possible to determine if there was any direct influence from airflow rate since both particle and biological data showed no correlation with upward airflow rates and velocities. Typical emissions resulting from a 6 L toilet flush were in the range of 280-400 particles per second at a concentration of typically 9-12 number per cm3 and a total particle count in the region of 3000 to 4000 particles, whereas the peak emissions from a 1.2 L toilet flush were 60-80 particles per second at a concentration of 2.4-3 number per cm3 and a total particle count in the region of 886 to 1045 particles. The reduction in particles is in direct proportion to the reduction in toilet flush volume. The slit-to-agar sampler was able to provide viable time course CFU data and confirmed the origin of the particles to be the tracer microorganism flushed into the system. The time course data also have characteristics consistent with the unsteady nature of a toilet flush.Photocaging holds promise for the precise manipulation of biological events in space and time. However, current near-infrared (NIR) photocages are oxygen-dependent for their photolysis and lack of timely feedback regulation, which has proven to be the major bottleneck for targeted therapy. Herein, we present a hypoxia-dependent photo-activation mechanism of dialkylamine-substituted cyanine (Cy-NH) accompanied by emissive fragments generation, which was validated with retrosynthesis and spectral analysis. For the first time, we have realized the orthogonal manipulation of this hypoxia-dependent photocaging and dual-modal optical signals in living cells and tumor-bearing mice, making a breakthrough in the direct spatiotemporal control and in vivo feedback regulation. This unique photoactivation mechanism overcomes the limitation of hypoxia, which allows site-specific remote control for targeted therapy, and expands the photo-trigger toolbox for on-demand drug release, especially in a physiological context with dual-mode optical imaging under hypoxia.
Minimal evidence exists supporting therapeutic selections for equine placentitis. The goal of this study was to characterize the anti-inflammatory effects of firocoxib when administered to mares with placentitis.
Mares (gestation D270-300) were assigned to INFECT (n=6; placentitis, no treatment), FIRO (n=6; placentitis, firocoxib, 0.1mg/kg, PO, daily), and NORM (n=6; no infection/treatment). Allantoic fluid (8hours, 24hours, birth) and amniotic fluid (birth) were collected from mares after infection. Concentrations of IL-1β, IL-6, TNF-α, IL-10, PGF
, and PGE
in fluids were measured by ELISA. Rocaglamide mRNA expression of IL-1β, IL-6, TNF-α, IL-8, IL-10, matrix metalloproteinases (MMPs) -1, 3, and 9 in fetal membranes/fetuses was quantified using real-time PCR.
Allantoic TNF-α concentrations were lowest in FIRO at 8hours and 24hours post-infection; IL-6 concentrations were lower in FIRO than NORM at 8hours, lower in FIRO than INFECT at 24hours post-inoculation, and lower in NORM than FIRO or INFECT at birth. Marginal mean allantoic IL-β and IL-10 concentrations were lower in FIRO and NORM than INFECT. Amniotic fluid cytokines were lowest in NORM with all measurements in that group being below the limit of detection. Allantoic PGF
concentrations were lower in FIRO and INFECT than NORM at 8hours post-inoculation, and lower in FIRO than INFECT or NORM at 24hours post-inoculation. Allantoic PGE
concentrations were lower in FIRO than INFECT. Amniotic PGF
and PGE
concentrations were lower in NORM than INFECT. In fetal membranes, group differences with respect to IL-1β, IL-6, IL-8, and MMP1 were dependent on tissue type.
