Chlorine dioxide (ClO2) is widely used as a drinking water disinfectant in many countries. Due to its antibiotic and antiviral capacity, it has aroused interest as a potential therapeutic agent with respect to the COVID-19 disease, AIDS and Influenza. As a result of this debate in scientific and governmental settings, it was deemed highly timely to...

Universidad de Almería (España) pcampra@ual.es Resumen: Los niveles y condiciones de toxicidad del dióxido de cloro y del clorito han sido determinados por numerosos estudios e informes emitidos por organismos oficiales, en particular del gobierno norteamericano. De acuerdo con dichos informes, no hay base experimental para afirmar que exista ries...

The effects of increasing the surface reflectance by albedo modifications have been evaluated using an air quality modelling system. We have evaluated the influence over pollutant concentrations of increasing from 0.20 to 0.55 the roof surface albedo (scenario called Albedo1) and increasing from 0.15 to 0.30 the ground surface albedo and from 0.20...

Gazpacho is a traditional cold soup of the Mediterranean diet consisting of a main base of fresh pureed tomato and other vegetables. Tomato and tomato products have demonstrated chemopreventive activity against several types of cancer through in vitro studies, and in animal and clinical research. Here we have applied a whole-food approach for the p...

The magnitude of the trends of environmental and climatic changes is mostly derived from the slopes of the linear trends using ordinary least-square fitting. An alternative flexible fitting model, piecewise regression, has been applied here to surface air temperature records in southeastern Spain for the recent warming period (1973–2014) to gain ac...

A long-term local cooling trend in surface air temperature has been monitored at the biggest concentration of reflective greenhouses in the world, at the Province of Almeria, SE Spain, associated with a dramatic increase in surface albedo in the area. The availability of reliable long-term climatic field data at this site offers a unique opportunit...

The essential oil of Artemisia campestris and the ethanol-water, hexane and water extracts of A. campestris and Thymelaea hirsuta collected in southern of Tunisia were investigated for their antioxidant (DPPH, ABTS and beta-carotene methods) and antitumor growth inhibition of human colon cancer HT-29 cells using MTT test activities. All the A. camp...

Purpose Climate change impacts in life cycle assessment (LCA) are usually assessed as the emissions of greenhouse gases expressed with the global warming potential (GWP). However, changes in surface albedo caused by land use change can also contribute to change the Earth’s energy budget. In this paper we present a methodology for including in LCA t...

A chemical-ecology approach has been used to screen plants growing in Guyana Highlands as an indicator of production of biologically active secondary metabolites. Extracts of leaves from 19 species, most of them endemic in this area, and collected at the top of Roraima Tepui (2,723 m) were screened in vitro at different concentrations for their pot...

Greenhouse horticulture has experienced in recent decades a dramatic spatial expansion in the semiarid province of Almeria, in southeastern (SE) Spain, reaching a continuous area of 26,000 ha in 2007, the widest greenhouse area in the world. A significant surface air temperature trend of -0.3°C decade-1 in this area during the period 1983-2006 is f...

Several oil sources of gamma-linolenic acid (GLA) were extracted from their corresponding seeds using several extracting systems: A, supercritical fluid extraction (CO2-SFE); B, methanol/acetyl chloride/hexane (1:0.05:0.5, v/v/v); C, chloroform/methanol/water (1:2:0.8, v/v); D, hexane/diethyl ether (1:1.5, v/v); E, hexane/ethanol (96%) (1:0.9, v/v)...

The essential fatty acid -linolenic acid (GLA, 18:3n6), which has several pharmaceutical properties, has been purified from Echium fastuosum seed oil. The procedure was effected through a two-step process. First, the oil was simultaneously extracted, saponified and concentrated by applying the solubility difference method, and then, the mother mixt...

New strategies of research have proven an efficient and rapid tool for natural drug discovery. For instance, a chemical-ecology approach has been used to screen plants according to their plant growth habitat as an indicator of production of biologically active secondary metabolites. Venezuelan Tepuys are uplifted mountains surrounded by forests or...

The functional properties of the Porphyridium cruentum, Nannochloropsis spp. and Phaeodactylum tricornutum defatted microalgal biomasses were investigated and compared with those of soybean flour. The following properties were evaluated for each microalgal biomass: nitrogen solubility, water and oil absorption capacities, emulsification capacity, v...

Seeds from 50 species belonging to the family Caryophyllaceae, subfamilies Alsinoideae, Silenoideae, and Spergulaceae, were surveyed in a search for new sources of γ-linolenic acid (GLA) having low levels of other interfering PUFA and therefore appropriate for GLA purification. It was detected mainly in Alsinoideae species, with a maximum of 15.6%...

Solvent winterization of seed oil and free fatty acids (FFAs) was employed to obtain gamma-linolenic acid (GLA; 18:3omega6) concentrates from seed oils of two Boraginaceae species, Echium fastuosum and Borago officinalis. Different solutions of seed oils and FFAs from these two oils at 10%, 20% and 40% (w/w) were crystallized at 4 degrees C, -24 de...

Four edible oils, linseed, borage and sunflower seed oils, and the liver oil of shortfin mako ( Isurus oxyrinchus ), have been fractionated by open column liquid chromatography, using partially argentated silica gel as stationary phase, looking for purify polyunsaturated fatty acids (PUFA).
