Kulinaria w przestrzeni miasta : nowe trendy, nowe potrzeby mieszkańców
2015
The subject of this article is culinary trends observable in Polish cities during the past few years. They include both the rediscovered practices, directly related to the cultural (culinary) heritage of a particular area, and these which have become popular only recently. According to the author, characteristic culinary fads are: the promotion of local delicacies on a large scale, growing interest in shopping in farmers’ markets offering organic produce (bio-markets) and traditional goods, growing popularity of street food (including street food festivals and picnics), and organizing the so called “breakfast on the grass” events.
Immunostimulatory Potential of Natural Compounds and Extracts: A Review
2020
The proper functioning of human immune system is essential for organism survival against infectious, toxic and oncogenic agents. The present study aimed to describe the scientific evidence regarding the immunomodulatory properties of the main micronutrients and specific phytochemicals. Plants of food interest have the ability to dynamically affect the immune system through particular molecules. Plant species, type of compounds and biological effects were herein reviewed mainly focusing on plants which are not commonly used in food supplements. Several efficient phytoproducts showed significant advantages compared to synthetic immunomodulators, being good candidates for the development of i…
A Participatory Agrobiodiversity Conservation Approach in the Oases: Community Actions for the Promotion of Sustainable Development in Fragile Areas
2021
Rural development policies today include significant directions towards ecological transition and sustainability. Biodiversity plays a fundamental role, especially in fragile environments. The North African oases, for example, are socio-ecological structures with delicate balances in terms of natural resources, where the activation of participatory conservation approaches appears today to be very useful, aiming at long-lasting results. This type of approach was applied in the oasis of El Hamma, in Tunisia. The socio-ecological analysis was carried out through semi-structured interviews with different stakeholders of the oasis. The results were used to activate focus groups and to identify, …
Quantifying the evolution of animal dairy intake in humans using calcium isotopes
2021
International audience; The contribution of dairy products to modern human diets has a debated role in the expansion of Neolithic economies and the dynamics of demographic transitions. While current methods allow discussing dairy production and processing, no approach allows reconstructing quantitatively its effective consumption. Calcium isotopes (δ44/42Ca) potentially represent such a marker due to the abundance of isotopically fractionated Ca in dairy products. Here, we test Ca isotope sensitivity to dietary intake of dairy product: we first used a dietary model based on a compilation of available data of dietary Ca sources; we then compared the modelled outputs to available and newly ac…
The production of traditional building materials in Oristano (Sardinia, Italy)
2016
The study of ceramic-making communities which employ traditional practices can provide insights into the raw materials and techniques used over the centuries in a particular territory. The archaeometric study of ceramic products and of the raw materials used in their production is an effective complement to the existing ethnographic information. This paper focuses on the brick and tile making tradition of Oristano, a town in Central-Western Sardinia (Italy). Applying a combination of techniques, it includes an extensive analysis of traditional handmade and early industrial bricks and tiles, and a study of the local clays that may have been used as raw materials. Although we were unable to s…
The problem of misidentification between edible and poisonous wild plants: Reports from the Mediterranean area
2018
Abstract Today, in many European countries, people are looking for wild edible plants to experience new tastes and flavors, by following the new trend of being green and environmentally friendly. Young borage and spinach leaves can be easily confused by inexpert pickers with those of other plants, including poisonous ones, such as Mandragora autumnalis Bertol. (mandrake) or Digitalis purpurea L. (foxglove), common in southern and northern Italy respectively. In the last twenty years, several cases of intoxication by accidental ingestion of mandrake and foxglove have been reported. The purpose of this work was to perform a pharmacognostic characterization of young leaves from borage, mandrak…
What has been thought and taught on the lunar influence on plants in agriculture? Perspective from physics and biology
2020
This paper reviews the beliefs which drive some agricultural sectors to consider the lunar influence as either a stress or a beneficial factor when it comes to organizing their tasks. To address the link between lunar phases and agriculture from a scientific perspective, we conducted a review of textbooks and monographs used to teach agronomy, botany, horticulture and plant physiology; we also consider the physics that address the e ects of the Moon on our planet. Finally, we review the scientific literature on plant development, specifically searching for any direct or indirect reference to the influence of the Moon on plant physiology. We found that there is no reliable, science-based evi…
Production of rosmarinic acid and salvianolic acid B from callus culture of Salvia miltiorrhiza with cytotoxicity towards acute lymphoblastic leukemi…
2016
Salvia miltiorrhiza (SM) Bunge is one of the widely-used Chinese medicinal herbs. In this study, the chemical constituents and anticancer potential of SM stems and leaves were examined with those of respective callus cultures. The callus culture for stem and leaf explants was initiated in modified Murashige and Skoog (MS) medium. Active constituents of respective extracts were analyzed by high performance liquid chromatography coupled with DAD and MS (HPLC-DAD-MS). Rosmarinic acid (RA) and salvianolic acid B (Sal B) were determined to be the main phenolic compounds. Quantitative analyses revealed that callus stem extracts produced higher amount of RA and Sal B (stem RA: 1.27±0.38%; stem Sal…
Antioxidant Phenolic Compounds in Salvia officinalis L. and Salvia sclarea L.
2018
Abstract The differences in the chemical composition of the phenolic compounds of Salvia officinalis versus Salvia sclarea growing in different habitats, were studied. First, the optimal solvent - methanol - for ultrasonic extraction of phenolic compounds from these plants was chosen experimentally. Total phenolic content and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays were determined spectrophotometrically. Total phenolic content was in the range of 63.9 to 134.4 mg GAE/g of plant depending on the studied species. The highest antiradical activity was displayed by the methanol fractions of S. sclarea varieties (83 and 67%). HPLC-DAD analysis of extracts was done in order to identify the pre…
Will legal international rhino horn trade save wild rhino populations?
2020
Wild vertebrate populations all over the globe are in decline, with poaching being the second-most-important cause. The high poaching rate of rhinoceros may drive these species into extinction within the coming decades. Some stakeholders argue to lift the ban on international rhino horn trade to potentially benefit rhino conservation, as current interventions appear to be insufficient. We reviewed scientific and grey literature to scrutinize the validity of reasoning behind the potential benefit of legal horn trade for wild rhino populations. We identified four mechanisms through which legal trade would impact wild rhino populations, of which only the increased revenue for rhino farmers cou…
