Conventional treatment of prostate cancer need more specificity, and higher efficiency. The present work is the first attempt to utilize hydrogel-loaded carvacrol-based chemotherapy with fractionated photothermal therapy (F-PTT) using a 635 nm laser for its treatment. Gold nanobipyramids (AuNBPs) were used as drug carrier and photosensitizer.

Hydrogels in agriculture offer controlled release, however, face issues with rapid disintegration, swift release, and inability to protect active ingredients. To overcome this, the study presents a hydrogel delivery system that uses dopamine-functionalized nanoporous diatom (DE-PDA) microparticles entrapped in alginate and chitosan matrices to deliver plant growth hormone, gibberellic acid (GA) that suffers from instability, limiting its field application. Developed GA@hydrogel beads exhibited an encapsulation efficiency of 85.

Military personnel often encounter situations that can trigger acute stress, which may affect operational performance. Therefore, it is important to examine stress responses in controlled environments to obtain more insights in performance-influencing effects of acute stress. This study investigated the impact of passive heat exposure combined with virtual combat scenarios on cardiovascular and psychophysiological parameters in a controlled setting.

To unveil the mechanisms underlying the compromised growth in Atlantic wolffish when reared at higher temperatures, we investigated the relationship between temperature, growth rate, aerobic capacity, stress biomarkers, and gut barrier function. Juveniles acclimated to 10°C were maintained at 10°C (control) or exposed to 15°C for either 24 h (acute exposure) or 50 days (chronic exposure).

Fatty acids, in particular, are valued as phase change materials (PCMs) for their non-toxic, biodegradable nature and thermal stability. However, the leakage and supercooling issues during phase transitions limit their application. Microencapsulation of PCMs, while improving thermal response, often leads to supercooling, complicating temperature regulation and increasing energy consumption.
