Impact of Antibiotic-Induced Depletion of Gut Microbiota and Selenium Supplementation on Plasma Selenoproteome and Metal Homeostasis in a Mice Model
(American Chemical Society, 2021)Selenium (Se) is a micronutrient involved in important health functions and it has been suggested to shape gut microbiota. Limited information on Se assimilation by gut microbes and the possible link with selenoproteins ... -
Intramolecular Interception of the Remote Position of Vinylcarbene Silver Complex Intermediates by C(sp3)−H Bond Insertion
(Wiley, 2022)The trapping of the elusive vinylogous position of a vinyl carbene with an aliphatic C(sp3)−H bond has been achieved for the first time during a silver-catalyzed carbene/alkyne metathesis (CAM) process. A Tpx-containing ... -
Metabolic and molecular approaches for the integrated production of bioenergetic precursors in microalgae
(Universidad de Huelva, 2023)Microalgae are photosynthetic microorganisms with a great ability of adapting to adverse conditions, developing regulation mechanisms to maintain optimal carbon/nitrogen ratios in the cell for survival. When these ... -
Effect of sulphur on selenium accumulation and speciation in Nannochloropsis oceanica
(Elsevier, 2022)Sulphur (S) and selenium (Se) are chemically similar. Once Se is taken up, it substitutes S in S-containing amino acids. This study investigated the effect of S on selenite accumulation in the microalga Nannochloropsis ... -
Photomodulation of ultrastable host–guest complexes in water and their application in light-controlled steroid release
(Royal Society of Chemistry, 2022)The cucurbit[8]uril (CB8) synthetic receptor is shown to form high-affinity host–guest complexes with dicationic dithienylethene (DTE) photoswitches in water. ITC experiments combined with computational studies suggest ... -
Toenail zinc as a biomarker: Relationship with sources of environmental exposure and with genetic variability in MCC-Spain study
(Elsevier, 2022)Background: Toenails are commonly used as biomarkers of exposure to zinc (Zn), but there is scarce information about their relationship with sources of exposure to Zn. Objectives: To investigate the main determinants of ... -
Selenium supplementation influences mice testicular selenoproteins driven by gut microbiota
(Nature Research, 2022)Selenium is a well-known essential element with important roles in human reproductive health mainly due to its antioxidant character. This study aimed to investigate the potential role of selenoproteins on gut microbiota ... -
Enhancing the recovery of volatile fatty acids from strawberry extrudate through anaerobic fermentation at different pH values
(Elsevier, 2022)tasted products. Adequate management of this substrate would entail a new source of benefit for the berry sector, instead of a costly waste to be treated. The aim of this work is to assess the potential use of SE as a ... -
Antagonistic Interaction of Selenium and Cadmium in Human Hepatic Cells Through Selenoproteins
(Frontiers Media, 2022)Cadmium (Cd) is a highly toxic heavy metal for humans and animals, which is associated with acute hepatotoxicity. Selenium (Se) confers protection against Cd-induced toxicity in cells, diminishing the levels of ROS and ... -
Combinación de metodologías ómicas y mea-ómicas para estudiar el efecto de la suplementación de selenio y su interacción con la microbiota intestinal
(Universidad de Huelva, 2022)El selenio (Se) es un elemento esencial para la salud humana con importantes funciones para el organismo. Está presente de forma natural en el medio ambiente tanto en formas orgánicas como inorgánicas. En el organismo, se ... -
Consolidation of iron powder by electrical discharge
(Elsevier, 2022-07-25)Capacitor electrical discharge consolidation (CEDC) is a technique that uses the heat of the Joule effect of a high intensity electric current to consolidate powders. In this study, the effect of the precompaction pressure ... -
Single and joint effects of cadmium and selenium on bioaccumulation, oxidative stress and metabolomic responses in the clam Scrobicularia plana
(Elsevier, 2022)Selenium (Se) is a vital trace element for many living organisms inclusive of aquatic species. Although the antagonistic action of this element against other pollutants has been previously described for mammals and birds, ... -
Metallomic and Untargeted Metabolomic Signatures of Human Milk from SARS-CoV-2 Positive Mothers
(Wiley, 2022-06-29)Scope: Lack of information about the impact of maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the elemental and metabolomic profile of human milk (HM). Methods and results: An ... -
The Role of Microalgae in the Biogeochemical Cycling of Methylmercury (MeHg) in Aquatic Environments
(MDPI, 2022-09)Methylmercury (MeHg) is the most important and the most abundant organic Hg pollutant in the aquatic ecosystem that can affect human health through biomagnification. It is the most toxic organic Hg form, which occurs ... -
Enhanced wastewater bioremediation by a sulfur-based copolymer as scaffold for microalgae immobilization (AlgaPol)
(Elsevier, 2023)In recent years, there has been an increasing concern related to the contamination of aqueous ecosystems by heavy metals, highlighting the need to improve the current techniques for remediation. This work intends to address ... -
Exploring Nordic microalgae as a potential novel source of antioxidant and bioactive compounds
(Elsevier, 2023)Nordic microalgae are a group of photosynthetic organisms acclimated to growth at low temperature and in varying light conditions; the subarctic climate offers bright days with moderate temperatures during summer and cold ... -
Hollow-Fiber Liquid-Phase Micro-Extraction Method for the Simultaneous Derivatization, Extraction, and Pre-concentration of Organotin Compounds from Packed Fruit Juices
(Springer, 2022)Organotin compounds are widely employed as pesticides and fungicides in agriculture and as stabilizers for the industrial manufacture of polyvinyl chloride and other polymers. Accordingly, these endocrine disruptors can ... -
