“…Drought stress reduces photosynthetic pigments, CO 2 intake, photosynthesis and relative water contents, impairs cell division and elongation [3] and disturbs the balance between reactive oxygen species (ROS) and antioxidants [4]. Roots of rice seedling are also very sensitive to abiotic stresses because they inhibit the cell expansion and other attributes of root development system [5]. Nevertheless, enzymatic antioxidants such as superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT), and non-enzymatic antioxidants play a vital role in detoxifying ROS [6].…”

Changing climate, food shortage, water scarcity and rapidly increasing population are some of the emerging challenges globally. Drought stress is the most devastating threat for agricultural productivity. Natural plant growth substances are intensively used to improve the productivity of crop plants grown under stressed and benign environments. The current study evaluated whether leaf extract of different moringa (Moringa oleifera L.) could play a role in improving drought-tolerance of rice (Oryza sativa L.). Rice plants were grown under three drought conditions, i.e., no, moderate and severe drought (100, 75 and 50% field capacity, respectively). Moringa leaf extract (MLE) obtained from four landraces (Multan, Faisalabad, D. G. Khan and exotic landrace from India) was applied during critical crop growth stages, i.e., tillering, panicle initiation and grain filling. Drought stress adversely affected the gas exchange attributes, photosynthetic pigments, antioxidant enzymes’ activities, yield and quality parameters of rice. Application of MLE from all landraces significantly improved physiological, biochemical and yield parameters under stressed and normal environmental conditions. The highest improvement in gas exchange traits (photosynthetic rate, stomatal conductance and respiration rate), photosynthetic pigments (chlorophyll a, b and carotenoids) and enzymatic activities (superoxide dismutase, catalase) and oxidative marker (H2O2) was recorded with MLE obtained from Faisalabad landrace. The application of MLE of Faisalabad landrace also improved yield and grain quality of rice grown under drought stress as well as drought-free environment. Thus, MLE of Faisalabad can be successfully used to improve growth, productivity and grain quality of rice under drought stress.

“…Chl-mediated API was reported to be effective against S. aureus for food preservation and decontamination [ [ 39 , 40 ]]. Several other studies have also indicated an effective inactivation of planktonic S. aureus cells by photosensitized chlorophyllin copper sodium salt [ 41 ], or chlorophyllin sodium magnesium salt, which has a superior antimicrobial activity to the former under irradiation of blue light [ 42 ]. Hasenleitner and Plaetzer (2019) and Caires et al (2020) demonstrated the inactivation of planktonic S. aureus and MRSA cells, respectively, by a combination of red-light with chlorophyllin sodium magnesium salt [ [ 43 , 44 ]].…”

Infected wounds pose challenges such as exudate management, bacterial infections, and persistent inflammation, making them a significant challenge for modern dressings. To address these issues in infected wounds more effectively, we have developed aerogel‐hydrogel biphase gels (AHB‐gel) based on Dextran (Dex). The gel introduced in this study exhibits antibacterial and anti‐inflammatory properties in the process of wound therapy, contributing to accelerate wound healing. The aerogel phase exhibits exceptional water‐absorption capabilities, rapidly soaking up exudate from infected wound, thereby fostering a clean and hygienic wound healing microenvironment. Concurrently, the aerogel phase is enriched with hydrogen sulfide donors. Following water absorption and the formation of the hydrogel phase, it enables the sustained release of hydrogen sulfide around the wound sites. The experiments confirmed that hydrogen sulfide, by promoting M2 macrophage differentiation and reducing the levels of inflammatory factors IL‐6 and TNF‐α, effectively diminishes local inflammation levels at the wound site. Furthermore, the sodium copper chlorophyllin (SCC) component within the hydrogel phase demonstrates effective antibacterial properties through photodynamic antimicrobial therapy (PAT), providing a viable solution to wound infection challenges.This article is protected by copyright.
