The paper presents multi-sensor applications of Unmanned Aerial Vehicles (UAVs) on three different cases of study, belonging to the wide category of Cultural Heritage (CH). The contribution aims to examine the efficacy of different methodological approach of surveys made in VIS and TIR range with aerial platforms. The use of UAV on two archaeological areas, Çatalhöyük site (Konya, Turkey) and the Medicean Villa of Pratolino (Florence, Italy) and an application of precision agriculture in Lamole (Greve in Chianti, Italy) will be presented. In particular, the analysis will focus on the accuracy of the obtained data, in terms of both metric and image quality, the possible information to extract from the IR imaging, the relationship between costs and benefits and the total amount of information that can be gained. The two different fields of research (archaeological and agricultural one) show that there are some similarities in the approaches and which could be the improving to obtain using the aerial survey in the visual and IR bands.
Cruciferous vegetables have drawn a great deal of attention in cancer research because of their potential protective properties. In the present study, four vegetables viz. cabbage, cauliflower, kohlrabi and radish were procured and processed for cold extraction procedure using 70% ethanol. The extracts were subjected to the qualitative phytochemical analysis, quantitative estimation of glucosinolates content and in vitro antiproliferative activity by MTT assay on MCF7, DL and NIH-3T3 cell lines. The results of qualitative phytochemical analysis showed the presence of several bioactive compounds viz. polyphenols, flavonoids, terpenoids, steroids, glycosides and alkaloids. Quantitative estimation of glucosinolates in terms of potassium thiocyanate equivalence/5mg of extract revealed that the cabbage has highest content of glucosinolate (122.6 µg) followed by cauliflower (109 µg), kohlrabi (101.6 µg) and radish (60.2 µg). The four cruciferous vegetables registered notable cell proliferation inhibition at different concentrations (50, 100, 200, 400 and 800 µg/mL) in a dose dependent manner against three different cell lines. The results of antiproliferative activity was expressed in terms of IC 50. Among the four vegetables cabbage showed considerable cytotoxicity and cell proliferation inhibition with an IC 50 value of 192.5, 189.7, 589.7 µg/mL followed by cauliflower (378.7, 398.9, 597.9 µg/mL), kohlrabi (389.5, 396.9, 619.7 µg/ml) and radish (415.4, 423.3, 703.6 µg/ ml) in three different cell lines MCF7, DL and NIH-3T3, respectively.. The present study underlines the epidemiological surveys that cruciferous vegetables possess anticancer effects might be due to the presence of glucosinolates augmented with other phytochemicals.
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.
