“…Vanadium was higher in predators compared to scrapers from both sampling sites; contamination is usually caused by fossil fuel and coal combustion, the use of fertilizers, and pesticides [69]. Vanadium appears to be necessary for human health, but a specific function in aquatic invertebrates has not yet been found [70].…”

For this study, we measured the concentrations of 23 trace elements (Al, As, Ba, Bi, Cd, Cr, Co, Cu, Fe, Ga, Hg, In, Li, Mn, Mo, Ni, Pb, Se, Sr, Ti, Tl, V, and Zn) in the whole bodies of three functional feeding groups (FFG) (filterers—Hydropsychidae, scrapers—Heptageniidae, and predators—Odonata) of aquatic insects collected from two sites in the Po basin (Po Settimo and Malone Front, Northwest Italy) to determine: (a) how FFG influence trace element accumulations, (b) if scrapers accumulate higher elements compared to the other FFG, since they graze on periphyton, which represents one of the major sinks of metals, and (c) the potential use of macroinvertebrates to assess the bioavailability of trace elements in freshwater. The hierarchical clustering analysis generated three main groups based on trace element concentrations: the most abundant elements were Fe and Al, followed by Sr, In, Zn, V, Mo, and Cu. Tl was below the limit of detection (LOD) in all FFG. Ga was detected only in scrapers from both sites and Hg only in predators from Po Settimo. The principal component analysis showed that concentrations of Al, As, Bi, Cd, Co, Cr, Ga, Fe, In, Mn, Pb, Ni, and Sr were highest in scrapers, suggesting that trace elements accumulate from the ingestion of epilithic periphyton (biofilm). Odonata (predators) accumulate certain elements (Ba, Hg, Li, Se, V, Ti, and Zn) in higher concentrations by food ingestion composed of different aquatic organisms. Differently, Cu and Mo concentrations were the highest in filterers due to their bioavailability in the water column. Non-metric multidimensional scaling clearly differentiated the FFG based on their ability to accumulate trace elements. The findings from this study represent an important step toward the definition of an innovative approach based on trace element accumulation by macroinvertebrates.

“…Examples include magnesium in the prevention of atherosclerosis and potassium in reducing the risk of hypertension [ 51 ]. Furthermore, certain macro (Ca, Mg, K, Na) and micro-minerals (Fe, Cu, Zn, Mn) are required and sometimes essential for enzymatic reactions such as calcium for muscle contraction and blood clotting [ 52 , 53 ]. The mineral composition of the six analysed batches of Persimon ® is shown in Table 6 .…”

Potential Nutrition and Health Claims in Deastringed Persimmon Fruits (Diospyros kaki L.), Variety ‘Rojo Brillante’, PDO ’Ribera del Xúquer’

In Europe, nutrition and health claims made on food must be based on scientific evidence, which means a comprehensive evaluation by the European Food Safety Authority (EFSA) prior to authorisation. Processed foods are subject to numerous claims derived from the presence of bioactive compounds; however, natural food products, often the original sources of those compounds, are not habitually the subject of these claims. Although the consumption of persimmon fruit has important health benefits, up to date no specific health claims are authorised for this fruit. In this work, ‘Rojo Brillante’ persimmon fruits (Diospyros kaki L.), Protected Designation of Origin (PDO) ‘Ribera del Xúquer’ were characterized regarding the presence of fiber (soluble and insoluble), vitamin C (ascorbic and dehydroascorbic acids), carotenoids (neoxanthin, violaxanthin, β-cryptoxanthin, lycopene, β- carotene) and mineral elements (Fe, Cu, Zn, Mn, Ca, Mg, Na, K). Different fruit batches harvested in different seasons were analyzed by standardized analytical methods (Association of Official Analytical Chemists, AOAC), high-performance liquid chromatography with ultraviolet detection (HPLC-UV) and atomic absorption spectroscopy. Based on the results, Persimon® is potentially able to show two nutrition claims “Source of fiber” and “Sodium-free/salt-free”. This work could set the ground for future studies and to start considering natural food products as candidates for the use of approved claims.

“…Meanwhile, hematocrit, serum creatinine, calcium and 1,25-dihydroxy-vitamin D (1,25D) levels were comparable to wt littermates [ 45 ]. Taken together, besides elevated PTH concentrations, increased FGF-23 in FGF-2HMWtg mice activates the renal Klotho-FGFR-1-pErk1/2 complex, resulting in downregulation of the type 2a sodiumphosphate co-transporter (NPT2a) in the proximal tubulus of the kidney, additionally leading to less phosphate absorption [ 45 , 82 , 84 , 85 ]. In order to counteract hypophosphatemia in FGF-2HMWtg mice, a promising approach was achieved by a continuous high phosphate diet, which was able to normalize the exaggerated serum FGF-23 level [ 45 ].…”

Fibroblast growth factor 2 (FGF-2), ubiquitously expressed in humans and mice, is functionally involved in cell growth, migration and maturation in vitro and in vivo. Based on the same mRNA, an 18-kilo Dalton (kDa) FGF-2 isoform named FGF-2 low molecular weight (FGF-2LMW) isoform is translated in humans and rodents. Additionally, two larger isoforms weighing 21 and 22 kDa also exist, summarized as the FGF-2 high molecular weight (FGF-2HMW) isoform. Meanwhile, the human FGF-2HMW comprises a 22, 23, 24 and 34 kDa protein. Independent studies verified a specific intracellular localization, mode of action and tissue-specific spatiotemporal expression of the FGF-2 isoforms, increasing the complexity of their physiological and pathophysiological roles. In order to analyze their spectrum of effects, FGF-2LMW knock out (ko) and FGF-2HMWko mice have been generated, as well as mice specifically overexpressing either FGF-2LMW or FGF-2HMW. So far, the development and functionality of the cardiovascular system, bone formation and regeneration as well as their impact on the central nervous system including disease models of neurodegeneration, have been examined. This review provides a summary of the studies characterizing the in vivo effects modulated by the FGF-2 isoforms and, thus, offers a comprehensive overview of its actions in the aforementioned organ systems.
