“…The mean Cu daily intake by participants in this study in urban area (2.25 mg/day) was slightly lower than 2.7 mg/ day reported by Shokunbi, et al [21] in foods analysed in the Nigerian Food Composition Table and 2.7 mg/day reported by Bowen [22] for Germans and was slightly higher than 2.1 mg/day reported by Rubio, et al [23] for Spanish population.…”

This study estimated the non-carcinogenic health risk of Pb, Cu, Cd, Zn via dietary intake in the urban and rural areas of Baia Mare city, northwestern Romania, a former mining area. A total of 230 food items grouped in ten food categories (meat and animal organs, meat-derived products, animal fat, eggs, dairy, bread, corn flour, potato, vegetables, fruits) and 32 water samples were collected and analyzed for Pb, Cu, Cd and Zn using atomic absorption spectrometric method. The human health risk assessment through dietary exposure was evaluated by calculating the estimated daily intake of metals, the Target Hazard Quotients (THQ) and the Total Target Hazard Quotients (TTHQ) for normal daily consumption in adults. The average daily intakes of Pb, Cd and Zn were higher than the Tolerable Daily Intake (TDI) reference value for urban and rural residents, which showed that there was a potentially high risk of ingestion of food and water. The average daily intake of Cu with food and drinking water was lower than the corresponding TDI value, which indicated that Cu intake was not a potential hazard to the health of residents in the study areas. The individual target hazard quotients, calculated for food consumption in urban area decreased in the following order: Cd>Cu>Pb>Zn, and in rural area: Pb>Cd>Cu>Zn, having values higher than 1 for Pb and Cd in the rural area and approximately equal to 1 for Cd (urban) and Cu (rural), indicating non-carcinogenic adverse health effects. The TTHQs for the two areas (urban and rural) were 2.934 and 5.164, respectively, established cumulative adverse effects of metals. The results showed that vegetables, potato and bread were the main sources of metal intake from foodstuff for adults, but fruit, water and meat were secondary contributors.

“…Zinc is the last 3d-metal in the periodic table, and it is extremely useful due to its numerous applications in different fields such as animal [350] and human diets [351], galvanizing solutions [352], cosmetics [353], and potential pharmaceutics [354]. Due to its relatively low costs it has been widely studied as a metallic source of several catalysts, either in its metallic [355], or in its ionic form [356].…”

Several valuable biologically active molecules can be obtained through C–H activation processes. However, the use of expensive and not readily accessible catalysts complicates the process of pharmacological application of these compounds. A plausible way to overcome this issue is developing and using cheaper, more accessible, and equally effective catalysts. First-row transition (3d) metals have shown to be important catalysts in this matter. This review summarizes the use of 3d metal catalysts in C–H activation processes to obtain potentially (or proved) biologically active compounds.

“…It also promotes T‐cell growth and differentiation (Gombart et al, 2020 ) (Figure 3 ), increases the number of circulating B cells, stimulates B‐cell responses, and maintains the activity of SOD (Ibrahim & El‐Sayed, 2016 ; Wintergerst et al, 2007 ). Copper‐rich foods include S. melongena (eggplant), A. hypogaea (groundnut), Bos taurus indicus (beef), Clarias gariepinus (catfish), Juglans regia (walnut), and Abelmoschus esculentus (okra) (Shokunbi et al, 2019 ).…”

The flare‐up in severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) that emerged in December 2019 in Wuhan, China, and spread expeditiously worldwide has become a health challenge globally. The rapid transmission, absence of anti‐SARS‐CoV‐2 drugs, and inexistence of vaccine are further exacerbating the situation. Several drugs, including chloroquine, remdesivir, and favipiravir, are presently undergoing clinical investigation to further scrutinize their effectiveness and validity in the management of COVID‐19. Natural products (NPs) in general, and plants constituents specifically, are unique sources for various effective and novel drugs. Immunostimulants, including vitamins, iron, zinc, chrysin, caffeic acid, and gallic acid, act as potent weapons against COVID‐19 by reinvigorating the defensive mechanisms of the immune system. Immunity boosters prevent COVID‐19 by stimulating the proliferation of T‐cells, B‐cells, and neutrophils, neutralizing the free radicals, inhibiting the immunosuppressive agents, and promoting cytokine production. Presently, antiviral therapy includes several lead compounds, such as baicalin, glycyrrhizin, theaflavin, and herbacetin, all of which seem to act against SARS‐CoV‐2 via particular targets, such as blocking virus entry, attachment to host cell receptor, inhibiting viral replication, and assembly and release.
