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.

Abstract. The dynamics of growing collisional orogens are mainly controlled by buoyancy and shear forces. However, the relative importance of these forces, their temporal evolution and their impact on the tectonic style of orogenic wedges remain elusive. Here, we quantify buoyancy and shear forces during collisional orogeny and investigate their impact on orogenic wedge formation and exhumation of crustal rocks. We leverage two-dimensional petrological–thermomechanical numerical simulations of a long-term (ca. 170 Myr) lithosphere deformation cycle involving subsequent hyperextension, cooling, convergence, subduction and collision. Hyperextension generates a basin with exhumed continental m…

Construct validity of the LSB-50 in argentinean adults: cross-validation and factorial invariance

2015

El trabajo se propone aportar evidencias de validez referidas al Listado de Síntomas Breve (LSB-50; de Rivera y Abuín, 2012), instrumento psicométrico de screening para medir síntomas sicológicos, analizadas en una muestra de adultos argentinos. Los participantes fueron 1291 individuos distribuidos proporcionalmente según sexo (51% mujeres; 49% varones) con edades entre 18 y 89 años (M = 38.9, DE = 16.49). Se llevaron a cabo estudios de validación cruzada e invarianza factorial para examinar si un modelo de siete factores que se correspondía con siete escalas clínicas (Hipersensibilidad, ObsesionesCompulsiones, Ansiedad, Hostilidad, Somatización, Depresión, y Alteraciones del sueño) present…

On the occurrence of the invasive Atlantic blue crab Callinectes sapidus Rathbun 1896 (Decapoda: Brachyura: Portunidae) in Sicilian inland waters

2022

The Atlantic blue crab Callinectes sapidus Rathbun, 1896 is included among the worst invasive alien species in the Mediterranean Sea. Here, we report the finding of the species in two Sicilian rivers, the Irminio and the Imera Meridionale, where it was collected up to 6 km from the river mouths. Although several records of the species are already available from Italy, this is the first evidence of the occurrence of this invasive crab so far from the coastline in the whole country. In the light of the well-known impact of the Atlantic blue crab on the invaded water bodies, the monitoring of the species and appropriate mitigation strategies should be implemented in order to protect the threat…

Cruise tourism effects on the mediterranean islands' economies

2009

Precedent studies show that cruises are able to generate daily visitors distributing additional expenditure for tourist destinations, giving new possibilities to support existing and future local economic activities. For Mediterranean islands, particularly related to this kind of tourism, the economic effects of cruise tourism seem to be different if compared with other territories, here defined as mainland. The aim of this paper is to analyze the effects of cruise tourism in the Mediterranean ports of call for insular and non insular territories. By focusing on Daily Cruise Visitors behaviour and by analyzing the passengers spending patterns in this work, we evaluated the economic effects …

Acute Toxicity Tests with Cadmium, Lead, Sodium Dodecyl Sulfate, and Bacillus thuringiensis on a Temporary Pond Ostracod

2012

A complete assessment of effects of pollutants in the environment requires the use of a wide assemblage of test organisms. Crustaceans have been widely used in aquatic environments, but within this group, ostracods have been overlooked, even though they are one of the commonest groups of animals in temporary waters. Within this framework, static acute toxicity bioassays were conducted with heavy metals Cd and Pb, the surfactant SDS and spores of the bacteria Bacillus thuringiensis var. israeliensis using adult parthenogenetic females of the temporary pond ostracod Heterocypris bosniaca. Experiments were run at 20 °C and in a 12 by 12 h photoperiod. The toxicity tests results are expressed a…

Ability of soil bacterial composition as an indicator of levels of soil erosion in a badland

2022

Calanchi (plural of calanco) are typical Italian badlands created by a combination of morphogenetic processes (rill and interrill erosion, gullying, piping, and mass movements) mainly originated by the effect of water. Calanchi are characterized by the sparse and patchy distribution of vegetation, and, in interplant areas, the soil surface is colonized by an association of organisms known as biological soil crust (BSC). A morphometric analysis of 45 basins in the studied calanchi area, based on a high-resolution digital elevation model, showed those basins are sediment removal systems characterized by rapid and relevant erosion processes. The goal of the current research is to evaluate the …

High-resolution analysis of trace elements in crustose coralline algae from the North Atlantic and North Pacific by laser ablation ICP-MS

2011

We have investigated the trace elemental composition in the skeleta of two specimens of attached-living coralline algae of the species Clathromorphum compactum from the North Atlantic (Newfoundland) and Clathromorphum nereostratum from the North Pacific/Bering Sea region (Amchitka Island, Aleutians). Samples were analyzed using Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) yielding for the first time continuous individual trace elemental records of up to 69 years in length. The resulting algal Mg/Ca, Sr/Ca, U/Ca, and Ba/Ca ratios are reproducible within individual sample specimens. Algal Mg/Ca ratios were additionally validated by electron microprobe analyses (Amch…
