Extracellular bioelectrical lexicon: detecting rhythmic patterns within dermal ...
Félix, Rute; Medeiros, Maria do Carmo; Elamine, Youssef; Power, Deborah Mary; Gomes, Henrique LeonelThis study uses a bioelectronic-based method to establish how non-electrogenic cells, like dermal fibroblast, employ bioelectrical signals to convey information. Electrophysiology using large-area Multielectrode Arrays (MEAs) devices revealed how populations of non-electrogenic cells in vitro generate patterns of bioelectrical signals. The period of the bioelectrical patterns depends on cell population activity...
Volatile characterization of honey with dominance of Bupleurum spinosum pollen
Elamine, Youssef; Machado, Alexandra M.; Estevinho, Leticia M.; Lyoussi, Badiâa; Figueiredo, Ana Cristina; Miguel, Maria GraçaMoroccan honey with Bupleurum spinosum (Apiaceae/Umbelliferae) as the main pollen source is locally known as Zantaz honey. In the present work, the volatiles from 18 honeys of this type, were isolated by hydrodistillation and analysed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS), for volatiles quantification and identification. The percentage composition of the volatiles and polle...
Electrical impedance spectroscopy for potassium content analysis and botanical ...
Elamine, Youssef; Inácio, Pedro M.C.; Miguel, Maria da Graça; Carlier, Jorge D.; Costa, Maria Clara; Estevinho, Leticia M.; Gomes, Henrique L.Minerals are reported to dominate the electrical properties of honey and indicate its botanical and geographical origins. In this study, Electrochemical Impedance Spectroscopy (EIS) was used to assess the relation between mineral elements, electrical properties and botanical origin using three honey varieties - Citrus sp., Eucalyptus sp., and Erica sp. These varieties are identified through pollen analysis and ...

Nutritional Characteristics of the Seed Protein in 23 Mediterranean Legumes
Elamine, Youssef; Alaiz, Manuel; Girón-Calle, Julio; Guiné, Raquel P. F.; Vioque, JavierThe search for new sources of plant protein for food and animal feed is driven by an increasing demand in developing countries and the interest in healthy alternatives to animal protein. Seeds from 23 different wild legumes belonging to tribes Gallegeae, Trifolieae, and Loteae were collected in southern Spain and their total amino acid composition was analyzed, by reverse phase-high performance liquid chromatog...
Organic food consumption and eating habit in Morocco, Algeria, and Tunisia duri...
Ben Khadda, Zineb; Ezrari, Said; Radouane, Nabil; Boutagayout, Abdellatif; El Housni, Zakariae; Lahmamsi, Haïtam; Zahri, Aziz; Houssaini, Tarik SqalliThe purpose of the current study is to understand how the COVID-19 pandemic has affected eating behavior and directed toward organic food and bioproducts consumption in the North African region especially Morocco, Algeria, and Tunisia as well as identify the variables that may affect the eating behavior of these population. Data were collected using an anonymous online survey on 1,244 respondents from Morocco, ...

Antibacterial activity of moroccan zantaz honey and the influence of its physic...
Elamine, Youssef; Imtara, Hamada; Miguel, Maria da Graça; Anjos, Ofélia; Estevinho, Leticia M.; Alaiz, Manuel; Girón-Calle, Julio; Vioque, JavierThe emergence of multidrug-resistant bacteria has prompted the development of alternative therapies, including the use of natural products with antibacterial properties. The antibacterial properties of Zantaz honey produced in the Moroccan Atlas Mountains against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus was evaluated and analyzed using chemometric tools. Minimum inhibitory concentrati...

Elamine, Youssef; Lyoussi, Badiâa; Miguel, Maria da Graça; Anjos, Ofélia; Estevinho, Leticia M.; Alaiz, Manuel; Girón-Calle, Julio; Martín, JesúsZantaz honey is a monofloral variety produced from the melliferous plant Bupleurum spinosum (Apiaceae), a shrub that grows mainly in the Atlas Moroccan Mountains. Determination of the polyphenol composition revealed that methyl syringate accounts for more than 50% of total polyphenols, which represents a very useful parameter for the characterization of this monofloral honey. Epicatechin, syringic acid and cate...
