Health Risk Assessment of Exposure to 15 Essential and Toxic Elements in Spanish Women of Reproductive Age: A Case Study

2021

This case study investigates the exposure of 119 Spanish women of reproductive age to 5 essential (Co, Cu, Mn, V, Zn) and 10 toxic (Ba, Be, Cs, Ni, Pb, Pt, Sb, Th, Al, U) elements and assesses their risk. The essential elements (Co, Cu, Mn, V, and Zn) showed average concentrations (GM: geometric mean) of 0.8, 35, 0.5, 0.2, and 347 μg/L, respectively. Five of the toxic elements (Ba, Cs, Ni, Al, U) exhibited detection frequencies of 100%. The GM concentrations of the novel toxic elements were 12 μg/L (Al), 0.01 μg/L (Pt), 0.02 μg/L (U), 0.12 μg/L (Th), 0.009 μg/L (Be) and 4 μg/L (Cs). The urine analysis was combined with a survey to assess any variations between subgroups…

A prospective observational study on oral administration of Ellagic Acid and Annona Muricata in patients affected by non-muscle invasive bladder canc…

2021

Introduction: BCG and MMC shortage and Covid-19 pandemic, more recently, limit accessibility to maintenance regimen in intravesical prophylaxis against recurrence of non-muscle invasive bladder cancer (NMIBC). Ellagic acid (EA) and Annona muricata (AM) exert antitumor activity against different human tumours. An observational prospective study on the prophylactic effect of oral administration of EA+AM in patients avoiding maintenance regimen is presented. Materials and methods: Patients affected by NMIBC and not undergoing maintenance after a 6-week course of intravesical prophylaxis with MMC or BCG were entered. Tis and very high-risk tumours were excluded. After informed consent, the pati…

Seaweed Extract Improves Lagenaria siceraria Young Shoot Production, Mineral Profile and Functional Quality

2021

Vegetable landraces represent the main source of biodiversity in Sicily. Lagenaria siceraria is appreciated by Southern Mediterranean consumers for its immature fruits and young shoots. Plant-based biostimulants supply, such as seaweed extract (SwE), is a contemporary and green agricultural practice applied to ameliorate the yield and quality of vegetables. However, there are no studies concerning the effects of SwE on L. siceraria. The current study evaluated the effects of SwE foliar application (0 or 3 mL L−1) on five L. siceraria landraces (G1, G2, G3, G4 and G5) grown in greenhouses. Growth traits, first female flower emission, fruit yield, young shoot yield, fruit firmness, young shoo…

Synergistic effects of neurons and astrocytes on the differentiation of brain capillary endothelial cells in culture

2003

Brain capillary endothelial cells form a functional barrier between blood and brain, based on the existence of tight junctions that limit paracellular permeability. Occludin is one of the major transmembrane proteins of tight junctions and its peripheral localization gives indication of tight junction formation. We previously reported that RBE4.B cells (brain capillary endothelial cells), cultured on collagen IV, synthesize occludin and correctly localize it at the cell periphery only when cocultured with neurons. In the present study, we describe a three-cell type-culture system that allowed us to analyze the combined effects of neurons and astrocytes on differentiation of brain capillary …

Digital Trace Data in the Study of Public Opinion

2016

In this article, we examine the relationship between metrics documenting politics-related Twitter activity with election results and trends in opinion polls. Various studies have proposed the possibility of inferring public opinion based on digital trace data collected on Twitter and even the possibility to predict election results based on aggregates of mentions of political actors. Yet, a systematic attempt at a validation of Twitter as an indicator for political support is lacking. In this article, building on social science methodology, we test the validity of the relationship between various Twitter-based metrics of public attention toward politics with election results and opinion pol…

Neuron-Glial Interaction During Injury and Edema of the CNS

1994

During injury and ischemia of the CNS mediator compounds are released or activated which cause secondary swelling and damage of nerve cells. Such mediators are glutamate, acidosis, free fatty acids, or high extracellular potassium. Glial homeostatic mechanisms are activated to prevent the secondary injury from these mediators. The glial clearance mechanisms have been studied in detail using in vitro systems allowing for a close control of the glial environment. Current evidence suggests glial swelling to occur together with glutamate uptake or in response to extracellular acidosis. Glial swelling, therefore, is rather the result of homeostatic mechanisms than an indication of glial demise.
