Brassica tardarae (Brassicaceae), a New Species from a Noteworthy Biotope of South-Western Sicily (Italy)
2020
A new species of Brassica sect. Brassica is described here from Sicily (Italy), which is known to be one of the centers of the diversification of wild taxa of this group. The new species (named Brassica tardarae) is restricted to the carbonate cliffs in the Tardara Gorges between Menfi and Sambuca di Sicilia (Agrigento province), an area with a peculiar geological history and where another strictly endemic species was recently described. The morphological relationships between the new species and other similar taxa are discussed, and an analytical key to the Sicilian taxa belonging to the genus Brassica sect. Brassica is also provided.
Relevance of the natural HDAC inhibitor sulforaphane as a chemopreventive agent in urologic tumors.
2018
Due to an increased understanding of molecular biology and the genomics of cancer, new and potent agents have been approved by the Food and Drug Administration (FDA) to fight this disease. However, all of these drugs cause severe side effects and resistance inevitably develops, re-activating tumor growth and dissemination. For this reason, patients turn to natural compounds as alternative or complementary treatment options, since it has been found that natural plant products may block, inhibit, or reverse cancer development. The present review focusses on the role of the natural compound sulforaphane (SFN) as an anti-tumor agent in urologic cancer. SFN is a natural compound found in crucife…
Mārtiņa Lapiņa fotografētais Aleksandra Zāmeļa portrets
2022
Godinot latviešu botāniķi un ģenētiķi Aleksandru Zāmeli 125 gadu jubilejā par mēneša priekšmetu Latvijas Universitātes Muzejs ir izvēlējies A. Zāmeļa portretu, ko fotografējis viens no 20. gadsimta pirmās puses izcilākajiem fotogrāfiem Mārtiņš Lapiņš. Raksts veltīts šai fotogrāfijai.
In vitro antifungal activity of allyl isothiocyanate (AITC) against Aspergillus parasiticus and Penicillium expansum and evaluation of the AITC estim…
2015
Abstract Isothiocyanates (ITCs) are natural compounds derived from cruciferous vegetables produced by enzymatic conversion of metabolites called glucosinolates. They are potentially useful antimicrobial compounds for food applications have been shown to be promising agents against cancer in human cell culture, animal models, and in epidemiological studies. In this study, the antifungal activity of the allyl isothiocyanate (AITC) was evaluated on two mycotoxigenic fungi as Aspergillus parasiticus and Penicillium expnsum , aflatoxins (AFs) and patulin (PAT) producers, employing an assay on solid medium. Also an approximation of the risk evaluation associated to the intake of food treated with…
Recatalogación de Vella lucentina M.B. Crespo (Cruciferae) según las categorías UICN (2001)
2006
Vella lucentina es un endemismo del centro de la provincia de Alicante que habita en matorrales esteparios calcícolas, bajo bioclima termomediterráneo semiárido. Su fragmentada área de ocupación apenas alcanza tres kilómetros cuadrados y se encuentra sometida a una fuerte presión antrópica, por lo que hasta el momento se tiene como especie “vulnerable” (VU), según las categorías de amenaza de la UICN. Sin embargo, últimamente se ha constatado una merma en la calidad de su hábitat y la desaparición de algunos núcleos poblacionales secundarios, a causa a actividades urbanísticas que amenazan a las restantes poblaciones. Los trabajos que se vienen realizando en los últimos meses sobre la biolo…
Child Nutrition and Bone Health
2018
AbstractNutrition is one of the modifiable factors that contributes to bone accrual during childhood and adolescence, a critical period to prevent adult osteoporosis. Calcium and vitamin D seem to be the most important nutrients for optimal bone growth. Requirements for calcium intake are different among countries and organizations, and exact recommendations are difficult to determine since other dietary factors directly affect calcium metabolism, such as salt intake and vitamin D levels. Some scientists have suggested that the actual calcium requirements are overestimated and that increased dairy intake does not necessarily translate to better bone health in adults. Moreover, calcium can b…
Typification of names inDrabasect.Aizopsis(Cruciferae, Arabideae) based on material from Italy
2013
Names of 20 presumed taxa in Draba sect. Aizopsis, all based on material from Italy, are considered. Full synonymies are provided, and types are designated (for 14 names) or indicated. Most of the taxa are currently considered unworthy of recognition, of which 16 belong to D. aspera sensu lato. However, the question of whether the Sicilian populations might be distinct from the peninsular populations is still unsettled.
Molecular Characterization of the Multigene Family Encoding the Different Glutamine Synthetase Isoforms in the Amphidiploid CROP Brassica Napus
1998
The fusion of the A genome of Brassica campestris (AA/n=10) and the C genome type of Brassica oleracea (CC/n=9) has led to the origin of the amphidiploid crucifer Brassica napus (AACC/n=19) [1], one of the most important oil crop in modern farming. The production of high quality industrial lubricants, edible oils and fatty acids or the supply of high protein press-residues for animal mast are only some utilizations of oilseed rape. Furthermore, rape oil can also be used for the manufacture of alternative fuels like ‘Bio-Dieser’.
An international case-control study of maternal diet during pregnancy and childhood brain tumor risk: a histology-specific analysis by food group.
2009
Maternal dietary data from an international collaborative case-control study on childhood brain tumors were used to evaluate associations between histology-specific risk and consumption of specific food groups during pregnancy.Nine study centers from seven countries contributed 1218 cases and 2223 controls. Most cases were diagnosed between 1982 and 1992 and ranged in age from 0 to 19 years. Dietary consumption was measured as average grams per day.Foods generally associated with increased risk were cured meats, eggs/dairy, and oil products; foods generally associated with decreased risk were yellow-orange vegetables, fresh fish, and grains. The cured meat association was specific to astroc…
Sociodemographic profiles regarding bitter food consumption. Cross-sectional evidence from a general French population
2013
International audience; Certain beneficial foods taste bitter (e.g., cruciferous vegetables) and might be aversive to consumers. Here, individual characteristics according to bitter food consumption patterns were assessed. The study included 2327 participants in the SU.VI.MAX antioxidant-based randomized controlled trial (1994-2002). The sample was drawn from the general French population. Dietary data were obtained from a minimum of twelve 24-h dietary records provided during the first 2 years of follow-up. Two bitter food consumption scores were computed - one assessing the variety of items consumed (unweighted score) and the other reflecting exposure to bitterness estimated via complemen…
