Development of some intestinal endocrine cell populations in water buffalo
No full textThe occurrence and distribution of different endocrine cell types in the gastrointestinal tract of large and small domestic mammals have been extensively studied (Ceccarelli et al. 1995; Agungpriyono et al.2000). Some studies have been also carried out on the ontogeny of gut endocrine cells in mammals (Ono et al. 1994), and only few in ruminant. (Kitamura et al. 1985; Guilloteau et al. 1997). In order to complete a previous study regarding postnatal development of intestinal endocrine cells (Lucini et al. 1999), in this study we report the appearance and distribution of some endocrine cell types in the gut of water buffalo during foetal development
Italian Lycium barbarum L. berry: Chemical characterization and nutraceutical value
No full textLycium barbarum L. has received considerable attention in recent years also in western countries because of the interesting healthy value of these berries. In this paper, goji samples cultivated in Southern Italy were analyzed for their chemical composition and nutritional profile in order to characterize fruits of Italian origin and to increase the awareness about their nutraceutical value. Lipid fraction was characterized by high percentages of unsaturated fatty acids, in particular oleic and linoleic acids, and very low values of atherogenic and thrombogenic indexes (0.1 and 0.2, respectively). In addition, goji berry was an interesting source of phytosterols (41.5 mg/100 g), essentially represented by β-sitosterol. Carotenoid analysis showed the presence of zeaxanthin, in esterified form, with high content of zeaxanthin dipalmitate (277.9 mg/100 g). Finally, in vitro antioxidant capacity and phenolic compounds were investigated. The results suggested that goji hydro-alcoholic extract possessed the ability to scavenge free radicals. Phenolic acids were clearly the most abundant compounds followed by flavonols and favanols. The results reported in this study confirm that Italian L. barbarum berry is a rich source of bioactive molecules with nutraceutical properties
Conventional, non-conventional extraction techniques and new strategies for the recovery of bioactive compounds from plant material for human nutrition
No full textCurrent food market demands authentic safe and nutritional food that is described as fresh and natural while being produced with sustainable industrial production (Granato et al., 2018). Functional foods is one such foods labeled as “natural health products” or “health foods” able to provide medicinal effects as well as be replacement to drug therapy (Brown, Caligiuri, Brown, & Pierce, 2018). Often such foods has some biologically active compounds (BACs) that are extracted from medicinal plants (Zhu et al., 2018), vegetables (Montesano, Rocchetti, Putnik, & Lucini, 2018; Poojary et al., 2017), fruits (Barba et al., 2017; Putnik & Bursać Kovačevć, 2017) or by-products from food production (Granato, Nunes, & Barba, 2017; Putnik et al., 2017). By-products of food production are very good sustainable and economic raw materials for food and pharmaceutical industry (Putnik et al., 2017)
Produzione, qualità e aspetti salutistici dell'Aloe
No full textAloe L., is the largest genus in the Xanthorrhoeaceae, (sub-family Asphodeloideae), a family of succulent-leaved, petaloid monocots. Aloes exhibit remarkable morphological variability and range in size from dwarf species to trees reaching heights of up to 20 m. Aloes are well represented in Southern Africa and especially South Africa, where they form an important component of the local flora from taxonomic, ethnomedicinal, chemical/chemotaxonomic, eco-touristic and horticultural perspectives.
They are cultivated in open fields in tropical and semitropical climates, in greenhouses in temperate climates, for ornamental, edible, medicinal and cosmetic purposes. The species A. vera (L.) Burm. f. and A. arborescens Mill. Are the most widely cultivated around the world.
Medicinal use of Aloe leaves dates back thousands of years and today aloes are world-renowned as a source of natural products derived from the leaf exudate and mesophyll. Mainly, active substances have been ascribed to β-polysaccharides (located in the inner leaf parenchyma) and phenolic compounds such anthrones, chromones and their glycosides. Among others, the therapeutic power related to these compounds includes wound-healing, antioxidant, antimicrobial, immunostimulant and anticancer properties.
The aim of this review is to provide an exhaustive collection of its bio-cultural values, health and therapeutic aspects and agronomic needs in order to improve the quantity and quality of the product. This knowledge will be of potential importance both to increase qualitative and quantitative traits of the production, as well as to protect biodiversity.
In vivo multiplication occurs through adventitious shoots that are formed on the underground stem but their formation is limited and has a seasonal frequency which makes this technique very slow and expensive. In vitro culture is an alternative propagation method, which facilitates large scale production in limited time and space.This review provides information for A. vera and A. arborescens about their pedo-climatic needs, agronomic aspects, both outdoors and in greenhouses, with particular reference to location and accommodation, irrigation and fertilization, as well as leaf production
Lipid Signaling Modulates the Response to Fumonisin Contamination and Its Source, Fusarium verticillioides, in Maize
No full textFumonisin-contaminated maize (Zea mays L.) products are a major health concern because of their toxic effects in humans and animals. Breeding maize for increased mycotoxin resistance is one of the key sustainable strategies for mitigating the effects of fumonisin contamination. Recent studies suggest a link between fumonisin accumulation and plant lipid and oxylipin profiles. However, the data collected so far do not reveal a cause-and-effect relationship. In this study, to decipher the multifactorial nature of mycotoxin resistance and plant–pathogen interaction mechanisms, we examined the oxylipin and complex lipid profiles of two maize hybrids (H21 and H22, the latter showing significantly lower FBs content) grown in the open field in two locations over 3years. Untargeted ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight (UHPLC-Q-TOF), together with chemometrics analysis, successfully distinguished between the two hybrids as having low- and high-level fumonisin contamination. Considering that H21 and H22 were exposed to the same environmental factors, the higher activation of lipid signaling systems in H22 suggests that other routes are enabled in the less susceptible hybrids to limit fumonisin B (FB) accumulation. Our results highlighted the crucial role played by oxylipin and sphingolipid signaling in modulating the complex maize response to F. verticillioides infection. Overall, our results returned a global view on the changes in lipid metabolites related to fumonisin accumulation under open field conditions, and revealed a strong activation of the lipid signaling cascade in maize in the presence of FB1
The exogenous application of wood vinegar induces a tissue- and dose-dependent elicitation of phenolics and functional traits in onion (Allium cepa L.)
No full textNovel insights on the valorisation of onion (Allium cepa L.) are required to decipher its potential as nutritional and health-promoting agent. Wood vinegar (WV) was exogenously applied to onion plants to determine its effectiveness as an elicitor. An untargeted UHPLC-QTOF-MS metabolomics approach was combined with evaluating the bioactivities of onion extracts. WV promoted tissue and dose-specific effects on onion metabolome, involving both primary and secondary metabolites. Accordingly, the antioxidant and enzyme-inhibiting properties of onion were significantly enhanced after WV treatment. Moderate to high WV concentrations, ranging 250–500 μL L−1, were found optimal at conferring the highest rates of biological activities. Polyphenols were related to the bioactivities of onion extracts since phenolic acids, flavanols, and flavonols were suggested as the contributors to their health-enhancing properties. This approach provides insight into the characterisation of WV as a natural elicitor and opens wide perspectives on the research of onion tissues as biofactories of functional ingredients
The Other Side of Resilience to Terrorism A Portrait of a Resilient-Healthy City
No full textThis timely treatise introduces an innovative prevention/preparedness model for cities to address and counter terrorist threats and events. It offers theoretical background, mixed-method research, and tools for creating a resilience-based response to terrorism, as opposed to the security-based frameworks commonly in use worldwide. The extended example of Milan as a “resilient-healthy” city pinpoints sociological, political, and economic factors that contribute to terror risk, and outlines how law enforcement and emergency management professionals can adopt more proactive measures. From these observations and findings, the author also makes recommendations for the professional training and city planning sectors to address preparedness issues, and for community inclusion programs to deter criminal activities in at-risk youth.
Features of the coverage:
- Summary of sociological theories of terrorism
- The Resilience D model for assessing and managing urban terrorist activity
- Findings on resilience and vulnerabilities of terror groups
- Photo-illustrated analysis of neighborhoods in Milan, describing areas of risk and resilience
- Virtual ethnography with perspectives from native residents, recent immigrants, and security experts
- Proposals for coordinated communications between resource agencie
Wine metabolomics and sensory profile in relation to terroir: a case study focusing on different wine-growing areas of Piacenza province (Italy)
No full textIn this work, a metabolomic approach based on ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC-ESI-QTOF) has been applied to investigate the untargeted phenolic profiles of wines from different growing areas, being Val Tidone, Val Nure and Val d'Arda, three valleys located in the province of Piacenza (Emilia Romagna, Italy). In this regard, eight "Gutturnio" DOC wines (both sparkling and still) from the same vintage (2016) were compared in order to highlight the impact of terroir on their phytochemical composition. At the same time, two white wines from the same vintage (2017) were analysed, being "Ortrugo" DOC and "Malvasia di Candia aromatica" DOC. Besides, a sensory evaluation was done in order to underline possible correlations between chemical and climatic data, as related to each growing area. Overall, interesting results were obtained by using UHPLC-ESI-QTOF mass spectrometry; white "Malvasia" and "Ortrugo" wines were very abundant in phenolic acids, being 107.36 and 98.36 mg/L, respectively, while among the "Gutturnio" wines, the highest content were recorded in still Gutturnio wines from Val Tidone and Val d'Arda (i.e., 389.92 and 388.18 mg/L, respectively). Unsupervised multivariate statistics (hierarchical clustering and principal component analysis) following metabolomics-based data allowed to clearly discriminate the different samples according to the corresponding growing-areas. Interestingly, the most discriminant compounds allowing sample grouping belonged to phenolic acids (such as isomeric forms of diferuloylquinic acid) and alkylphenols (such as 5-Heptadecylresorcinol). Besides, the venn diagram analysis revealed 7 common markers belonging to both conditions under investigation (i.e., terroir and winemaking typology). Finally, strong correlations were outlined when considering polyphenol profiles and climatic data, although further ad-hoc studies are extremely needed to confirm this trend
