Summary: The bactericidal effects of a self-designed device that combines intense pulsed light (IPL), plasma, and ultraviolet irradiation (UV) on granular and powdered foods were investigated. The combined IPL-plasma-UV system achieved the highest reduction of microorganisms on sesame seeds, while the effects were slightly lower on black pepper powder and red pepper powder.

Summary: This study investigated the efficacy and safety of intense pulse light (IPL) therapy and meibomian gland expression (MGX) in cases of recurrent chalaziosis after excision surgery. The results showed that IPL-MGX treatment significantly reduced the recurrence rate and improved meibomian gland function. Therefore, IPL-MGX can be considered as a first-line treatment for recurrent or refractory chalaziosis cases post excision.

Summary: The study indicated that using the IPL system alone and combining it with RF yielded similar results in hair reduction, but the combined treatment was more effective in long-term observations. These therapies were found to be safe, effective, and comfortable for patients with skin phototypes II or III.

Summary: This study investigated the bactericidal capacity of intense pulsed light (IPL) on Salmonella as well as the sublethal injuries caused by IPL treatment. The results showed that IPL treatment caused various intracellular oxidative damages in Salmonella, but these damages could be repaired in nutrient-rich environments. The study also identified two key repair mechanisms in Salmonella under IPL stimulus: repairing membrane proteins and addressing DNA damage.

Summary: The aim of this study was to assess the hyperspectral reflectance of acne skin before and after intense pulsed light (IPL) therapy and to compare it with the reflectance of healthy skin. The results showed that acne skin after IPL therapy had increased reflectance, similar to healthy skin. This indicates that IPL therapy increases the reflectance of acne skin by reducing chromophores, making it closer to the reflectance of healthy skin.

Summary: The study examined how intense pulsed light processing parameters affected aroma, flavor, and mouthfeel of nonfat dry milk, finding that increasing exposure time led to increased intensities of overall flavor and umami taste, while increasing temperature increased certain aromas. All levels of exposure time resulted in increased aroma and flavor, while appearance changes were only noticeable in milk powder at the highest exposure level and lowest temperature. The study highlights the importance of understanding critical factors impacting sensory properties for better implementation of this decontamination technology.

Summary: It has been reported that a significant amount of agricultural products worldwide is wasted every year due to mold contamination, leading to immense economic losses. Despite advancements in food technology, the issue of mold contamination still persists. This study explored the use of Intense Pulsed Light (IPL) as a non-thermal physical sterilization technique to inhibit fungal growth on food surfaces, demonstrating effective fungicidal rates for both planktonic and biofilm molds.

Summary: This study compared the efficacy of intense pulsed light (IPL) combined with meibomian gland expression (MGX) and instant warm compresses combined with MGX as treatments for meibomian gland dysfunction (MGD)-related dry eye disease (DED). The results showed that both methods were able to reduce inflammation, but the IPL group had a better inhibitory effect on the inflammatory cytokine IL-6. Additionally, some cytokines showed a downward trend during treatment, suggesting that the vicious cycle of DED was suppressed.

Summary: For bacteria, the transition from unicellular entities to multicellular biofilm communities generates distinct metabolic microenvironments. Dynamic and programmed metabolic responses allow the biofilms to react to local changes in nutrient levels and contribute to phenotypic antibiotic resistance of the community. Novel therapeutic approaches targeting biofilms may stem from these metabolic adaptations.

Summary: The distribution of free chlorine in a flume washer was studied, showing that at lower injection velocities chlorine tends to concentrate near the bottom of the flume, and the presence of soluble organic matter depletes free chlorine. Simulation of turbulent fluid flow in an industry-scale washer indicated that optimizing free chlorine injection strategy can result in a more uniform distribution.
