Objective: Many substances have been used for wound-burn treatment to date. Recent studies have focused not only on covering the wound but also on the production of dressings that will provide patient comfort at the highest level. This review mentions the types of dressings and the expected features of an ideal wound dressing. An ideal wound dressing should close the wound and protect against external factors such as microorganisms. It must have an appropriate absorption capacity for the exudate level in terms of not drying the wound. It should mimic healthy skin with mechanical strength and flexibility. Wound dressing is expected to accelerate healing by supporting cell proliferation and migration. Result and Discussion: One or more of these features come to the fore when the patient's age and chronic diseases, wound depth, degree, and stage are considered. As a result, since many factors are influential in wound dressing selection, it is crucial to examine the properties of materials. Wound dressings should be developed by considering tissue debridement, infection control, moisture balance, and epithelization.
In this study, one-year old grapefruit trees grafted onto sour Orange (SO) and C22 rootstocks were exposed to NaCl-induced salinity (approx. 6 dS m-1) in pot culture for two months under greenhouse conditions. The experiment was laid out in a randomized block design with eight replicates. The trees were irrigated with saline solution containing 0.1% liquid fertilizer "Miracle-Gro Liqua Feed 9-4-9" (N-P2O5-K2O) enriched with micronutrients. The experimental treatments consisted of three levels (4 mM, 8 mM, 12 mM) of foliar applied proline along with control application. Distilled water served as the control. During the experiment the seedlings were sprayed totally five times with ten days intervals. At the end of the treatment physiologically mature leaves, free of damage or defects, were sampled. Dried and ground leaf samples were used for chemical (Na and Cl) and biochemical (DPPH scavenging activity, reducing power, total phenolic content, proline) analysis. Spesific leaf area, leaf water relations and leaf gas exchange of the plants were also determined. Foliar PRO application decreased Na and Cl concentrations of the leaves, and improved spesific leaf area in the final dose. Water leaf relations, photosynthetic activity and biochemical parameters were affected positively even though some differences were determined between the cultivars.
In unmanaged ecosystems, soil nitrogen (N) released through mineralization of organic matter constitutes the source of N for the plants. In agro-ecosystems, N is applied additionally as mineral or organic fertilizers in order to compensate N which is removed with products. Adequate and timely application of fertilizer N as dictated that by contribution of soil N to crop production is important for minimizing production costs from overuse of N fertilizer and for reducing possible environmental impacts. Using 15 N-labelled fertilizers, it has now been convincingly proved that majority of the plant N comes from the soil N. Thus, soil N plays a vital role in supplying N to crop plants and dictates the efficiency of applied fertilizer N. Size of available N pool, though relatively small as compared to total soil N, throughout the crop growth season determines whether crop gets adequate N nutrition or N is lost from the soil-plant system. As fertilizer N contributes directly to available N pool and by N substitution to the soil organic matter pool, N management at that point following the principles of synchrony between crop N need and application of N through soil and fertilizer N can lead to high fertilizer NUE (nitrogen use efficiency). Evaluation of site-based N management in cereals using gadgets like chlorophyll meter, leaf colour chart or optical sensors or OTG (on the go) crop sensing spreaders revealed that same yields can be achieved with less N fertilizer applied but with enhanced fertilizer NUE and diminished losses of N to the environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
