Celiac Disease and Overweight in Children: An Update
Antonella Diamanti,Teresa Capriati,Maria Sole Basso,Fabio Panetta,Vincenzo Maria Di Ciommo Laurora,Francesca Bellucci,Fernanda Cristofori,Ruggiero Francavilla
Nutrients , 2014, DOI: 10.3390/nu6010207
Abstract: The clinical presentation of celiac disease in children is very variable and differs with age. The prevalence of atypical presentations of celiac disease has increased over the past 2 decades. Several studies in adults and children with celiac disease indicate that obesity/overweight at disease onset is not unusual. In addition, there is a trend towards the development of overweight/obesity in celiac patients who strictly comply with a gluten-free diet. However, the pathogenesis and clinical implications of the coexistence of classic malabsorption (e.g., celiac disease) and overweight/obesity remain unclear. This review investigated the causes and main clinical factors associated with overweight/obesity at the diagnosis of celiac disease and clarified whether gluten withdrawal affects the current trends of the nutritional status of celiac disease patients.
El aborto en las trayectorias de mujeres y varones de la ciudad de Buenos Aires
Petracci, Mónica;Pecheny, Mario;Mattioli, Marina;Capriati, Alejandro;
Sexualidad, Salud y Sociedad (Rio de Janeiro) , 2012, DOI: 10.1590/S1984-64872012000600008
Abstract: this article presents results of the argentine chapter of the hexca research project, on heterosexualities, contraception and abortion in four south american cities. in-depth interviews were conducted with 30 women and 30 men residing in the buenos aires metropolitan area, about their experiences of abortion as a landmark in their personal trajectories. findings show that illegality does not determine the decision to interrupt a pregnancy, but the differential conditions of its clandestine practice; abortion leaves a mark both on women and on men. for low-income women, the first pregnancy results in childbirth, then followed by an abortion; while for middle-class women the first pregnancy results in an abortion, then followed by children. the interruption of a pregnancy is not a response to exceptional situations, but an ordinary part of the process initiated by the suspicion of a pregnancy.
Greedy Friensdhip Decompositions of Graphs  [PDF]
Teresa Sousa
Open Journal of Discrete Mathematics (OJDM) , 2011, DOI: 10.4236/ojdm.2011.11004
Abstract: A graph that consists of t cliques sharing a vertex v is said to be a t-friendship graph with center v. A friendship graph is a graph that is t-friendship for some . We solve the problem of finding the best upper bound for the size of a greedy 2-friendship decomposition and a greedy friendship decomposition of graphs of order n.
The H-Decomposition Problem for Graphs  [PDF]
Teresa Sousa
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.311237
Abstract: The concept of H-decompositions of graphs was first introduced by Erd?s, Goodman and Pósa in 1966, who were motivated by the problem of representing graphs by set intersections. Given graphs G and H, an H-decomposition of G is a partition of the edge set of G such that each part is either a single edge or forms a graph isomorphic to H. Let Ф(n,H) be the smallest number Ф, such that, any graph of order n admits an H-decomposition with at most Ф parts. The exact computation of Ф(n,H) for an arbitrary H is still an open problem. Recently, a few papers have been published about this problem. In this survey we will bring together all the results about H-decompositions. We will also introduce two new related problems, namely Weighted H-Decompositions of graphs and Monochromatic H-Decom- positions of graphs.
4-Cycle Decompositions of Graphs  [PDF]
Teresa Sousa
Open Journal of Discrete Mathematics (OJDM) , 2012, DOI: 10.4236/ojdm.2012.24024
Abstract: In this paper we consider the problem of finding the smallest number such that any graph G of order n admits a decomposition into edge disjoint copies of C4 and single edges with at most elements. We solve this problem for n sufficiently large.
Friendship Decompositions of Graphs: The general problem  [PDF]
Teresa Sousa
Open Journal of Applied Sciences (OJAppS) , 2012, DOI: 10.4236/ojapps.2012.24B008
Abstract: A friendship graph is a graph consisting of cliques sharing a common vertex. In this paper we investigate the maximum number of elements in an optimal friendship decomposition of graphs of order n. We obtain upper and lower bounds for this number. These bounds relate this problem with the classical Ramsey numbers.
Justification of public investment initiatives on water transfer systems as an instrument for water balances in Spain: the case of the Júcar–Vinalopó water transfer system  [PDF]
Martin Sevilla, Teresa Torregrosa
Agricultural Sciences (AS) , 2011, DOI: 10.4236/as.2011.24067
Abstract: One of the most controversial issues in recent years in water management has been finding a balance between available resources and water needs related to certain territories. The changes brought about by a new awareness over the need to preserve the environment, the social perception of the ownership of the river channels, the need for adjust financial costs arising from the waterworks and the compliance with European standards urgently require redesign of water supply policies in force at this time. The Júcar-Vinalopó water transfer, considered as an historic aspiration for many years in the region, has been regarded as a key element for solving the depletion of groundwater in a large area located in the southeast of the Iberian Peninsula, mainly for irrigation purposes. In this paper we present an approach to the economic aspects related to the implementation of the project, its investment and financing arrangements and the question of the subsequent management with the impact of the well-known “recovery cost principle", highlighting the current difficulties in carrying out projects of this size, due to severe limitations, as social and economic conditions of the transfer.
Phosphoinositide and phospholipid phosphorylation and hydrolysis pathways
—Organophosphate and organochlorine pesticides effects
 [PDF]

Teresa Fonovich, Gladis Magnarelli
Advances in Biological Chemistry (ABC) , 2013, DOI: 10.4236/abc.2013.33A004
Abstract:

Phospholipid and phosphoinositide phosphorylation pathways have been shown to be of crucial importance on producing lipid mediators. The earlier findings reported on lipid molecules playing roles in different metabolic pathways used to assign them the exclusive role of second messenger generators. Several researchers have recently described how direct interaction of phospholipids and phosphoinositides with molecules or organelles, without the need for producing second messenger molecules, is responsible for their mechanism of action. Organophosphate and organochlorine pesticide toxicity mechanisms have been extensively studied in relation to their well known effects on cholinesterase activities and on the alterations of electric activity in the nervous system of different organisms respectively. There is little but consistent evidence that some compounds, including in both groups of pesticides, are also able to interact with phospholipid and phosphoinositide phosphorylation pathways in several organisms and tissues. The present review consists of an actualization of basic research on phospholipid and phosphoinositide phosphorylation and hydrolysis pathways, as well as a description of some reported evidences for the effects of the above mentioned pesticides on them.

Protein phosphorylation pathways disruption by pesticides  [PDF]
Gladis Magnarelli, Teresa Fonovich
Advances in Biological Chemistry (ABC) , 2013, DOI: 10.4236/abc.2013.35050
Abstract: Phosphosites in the human proteome represent an excellent source of potential biomarkers of pesticide toxicity. In fact, experimental animal models as well as in vitro studies have revealed phosphorylation disruption associated to metabolic regulation, hormone signaling, neuronal function and differentiation, cell survival and death. Due to their estrogen-mimicking ability, pesticides are considered as prime etiological suspects of increasing tumor incidence. Evidences of alterations in the signal transduction pathways involved in the tumor progression stage of pesticides were also provided. Despite progress in understanding the effect of pesticides on the human phosphorproteome and their health outcomes, it remains a complex issue to be studied. By now, the potential impact of pesticides in epigenetic phosphorylation pathways remains poorly explored. In addition, studies involving pesticides mixtures effects are needed. This review updates and provides a comprehensive discussion on the molecular and biochemical events underlying protein phosphorylation pathway disruption caused by pesticides most frequently detected in human tissues and fluids, such as organochlorine pesticides and organophosphates. The link between epidemiological studies and experimental approaches is also considered. Future challenges, such as micro-array phosphoproteome studies to complement gene expression arrays to understand the mechanisms involved in pesticide toxicology are briefly discussed.
Charting the Course for Sustainable Small Island Tourist Development  [PDF]
Teresa L. McKee
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.43030
Abstract:

This article, Charting the Course for Sustainable Small Island Tourist Development, addresses sustainability criteria for small island tourist development drawing on the history of development in the last decade in the Bocas del Toro archipelago of the Republic of Panama in the Caribbean Sea near the border of Costa Rica. Tax deferments for the development of vacation and resort properties spurred a boom in this island locale since the late 1980’s. Tourist Law 8 of the Panamanian constitution is referenced. Sustainability criteria of water supply and availability are suggested and outer island projects are discussed. Lessons are outlined and recommendations are made for permit qualifications that promote sustainable small island tourist development.
