Analysis of the Inland Port Regionalization Process in Spain

AbstractThe aim of this paper is to analyse and compare the ability of the main Spanish containers ports to penetrate into their inland territory along the last decade. To achieve this goal we firstly identify the inland origin of the container cargo by considering the location of the Spanish companies generating those flows in the peninsula. Then we determine the distribution of flows among the considered ports from 2000 to 2010, setting the boundaries of their hinterlands along that period. Finally we use two indexes to assess the evolution of these hinterlands in a complementary way: by their scope and their homogeneity.Furthermore, considering that the inter-port distribution of the traffic can change according to their composition, we repeat the analysis in a disaggregate way; that is, separately for each one of the main flows (by volume) of the Spanish foreign trade on the basis of the Combined Nomenclature Clasification.The main results show that the port of Valencia is the one whose hinterland has better evolved: by increasing its scope and by reducing its dependency both geographical as by type of flow. They also highlight that the main centres generating the maritime container flows are closer to this port than to the rest. Also these results allow us to conclude that this port regionalization process has not been oblivious to its economic environment but positively influenced by it

Unusual Tachycardia Association In A patient Without Structural Heart Disease

We report an unusual association of persistent atrial flutter and bundle branch re-entrant ventricular tachycardia in a young patient without structural heart disease. Atrial flutter masked the infra-Hisian conduction disease, was fundamentally dependent on a long PR interval, and could be a possible trigger of ventricular tachycardia

Yerba Mate Modulates Tumor Cells Functions Involved in Metastasis in Breast Cancer Models

Breast cancer (BC) is the most frequent cancer in women and tumor metastasis is a major cause of cancer-related deaths. Our aim was to evaluate anti-metastatic properties of yerba mate extract (YMe) in BC models. 4T1, F3II, MCF-7, and MDA-MB231 cell lines were used to perform in vitro assays. The F3II syngeneic mammary carcinoma model in BALB/c mice was used to evaluate tumor progression, BC metastasis and survival. Cells were inoculated subcutaneously into the flank for the heterotopic model and into the mammary fat pad for the orthotopic model. YMe was administered p.o. in a dose of 1.6 g/kg/day. In vitro YMe inhibited cell proliferation and reduced tumor cell adhesion, migration and invasion. These biological effects were cell-line dependent. In vivo YMe reduced tumor metastasis and increased mice survival in both models. Our preclinical results suggest that YMe could modulate tumor progression and metastasis in BC models.Fil: Garcia Lazaro, Rocio Soledad. Universidad Nacional de Quilmes; Argentina.

Anti-proliferative effects of a blueberry extract on a panel of tumor cell lines of different origin

Background: Blueberries are among the fruits with the highest antioxidant activity and have been recognized by their health promoting properties. Aim:In vitro study of the anti-proliferative effects of a blueberry extract on a panel of cancer cells from different origin. Materials and Methods: A blueberry extract was produced using ethanol as extracting solvent. The anti-proliferative activity of the extract was evaluated against seven tumor cell lines. The properties of blueberry extract to decrease cell adhesion and migration were also investigated. Results: Blueberry extract showed a dose-dependent inhibitory effect on cell proliferation for all cell lines. Non-cytotoxic concentrations of the extract decreased cell adhesion in five of seven cell lines studied and inhibited the migration of MDA-MB-231 and PC-3 tumor cells. Conclusion: This work provides additional evidence regarding the ability of blueberry extract to inhibit the growth and decrease cell adhesion and migration of different cancer cell lines in vitro. Key Words: anthocyanins, anti-proliferative, blueberry extract, cancer, polyphenols.Fil: Lamdan Ordas, Humberto. Universidad Nacional de Quilmes. Departamento de Ciencia y Tecnología.

Estudio de la yerba mate (Ilex paraguariensis) en el crecimiento y la progresión tumoral

Existen evidencias en la bibliografía que muestran la potencialidad antitumoral de la Yerba Mate en modelos in vitro aislados como proliferación, crecimiento o invasión. Ninguno de estos trabajos evalúa en modelos conjuntos in vitro e in vivo la administración crónica de la Yerba Mate mediante extractos sobre la progresión tumoral en modelos integrales. El laboratorio de Oncología Molecular, específicamente, uno de sus proyectos denominado «Fitomedicina y cáncer», ha estudiado en profundidad el rol de la Yerba Mate en modelos de progresión tumoral. Para ello, ha utilizado un extracto soluble de Yerba Mate secado por el método de secado spray. La identificación fisicoquímica indicó que este extracto contiene una mezcla compleja de fitoquímicos activos

Protein Kinase Mitogen-activated Protein Kinase Kinase Kinase Kinase 4 (MAP4K4) Promotes Obesity-induced Hyperinsulinemia

Previous studies revealed a paradox whereby mitogen-activated protein kinase kinase kinase kinase 4 (Map4k4) acted as a negative regulator of insulin sensitivity in chronically obese mice, yet systemic deletion of Map4k4 did not improve glucose tolerance. Here, we report markedly reduced glucose-responsive plasma insulin and C-peptide levels in whole body Map4k4-depleted mice (M4K4 iKO) as well as an impaired first phase of insulin secretion from islets derived from M4K4 iKO mice ex vivo After long-term high fat diet (HFD), M4K4 iKO mice pancreata also displayed reduced beta cell mass, fewer proliferating beta cells and reduced islet-specific gene mRNA expression compared with controls, although insulin content was normal. Interestingly, the reduced plasma insulin in M4K4 iKO mice exposed to chronic (16 weeks) HFD was not observed in response to acute HFD challenge or short term treatment with the insulin receptor antagonist S961. Furthermore, the improved insulin sensitivity in obese M4K4 iKO mice was abrogated by high exogenous insulin over the course of a euglycemic clamp study, indicating that hypoinsulinemia promotes insulin sensitivity in chronically obese M4K4 iKO mice. These results demonstrate that protein kinase Map4k4 drives obesity-induced hyperinsulinemia and insulin resistance in part by promoting insulin secretion from beta cells in mice

Age and growth of the Amazonian migratory catfish Brachyplatystoma rousseauxii in the Madeira River basin before the construction of dams

The goliath catfish Brachyplatystoma rousseauxii has crucial economical and ecological functions in the Amazon basin. Although its life history characteristics have been studied in the Amazon, there is little information in the Madeira River basin, which holds genetically distinct populations and where dams were recently built. Using fish collected in Bolivia, Brazil and Peru, this study provides a validation of growth rings deposition and details the growth patterns of B. rousseauxii in the Madeira before the dams' construction. Age structure and growth parameters were determined from 497 otolith readings. The species exhibits two growth rings per year and sampled fish were between 0 and 16 years old. In the Brazilian portion of the basin, mainly young individuals below 5 years old were found, whereas older fish (> 5 years) were caught only in the Bolivian and Peruvian stretches, indicating that after migrating upstream to reproduce, adults remain in the headwaters of the Madeira River. Comparing with previous publications, B. rousseauxii had a slower growth and 20 cm lower maximum standard length in the Madeira River than in the Amazon River. This study provides a baseline for future evaluation of changes in population dynamics of the species following dams closure.Santo Antonio Energia (SAE)Universidade Federal de Rondonia (UNIR)Instituto de Estudos e Pesquisas Agroambientais e Organizacoes Sustentaveis (IEPAGRO)CAPES [1402376, 047/2012, 6632/14-9]CNPq [204344/2015-8]Foundation of Support to Research of the Amazon [PAREV/FAPEAM 019/2010]FAPESP (Sao Paulo Research Foundation) [2016/07910-0]Univ Fed Rondonia UNIR, Dept Biol, Lab Ictiol & Pesca, BR 364,Km 9,5, BR-76801059 Porto Velho, RO, BrazilPrograma Posgrad Rede Biodiversidade & Biotechnol, BR 364,Km 9,5, BR-76801059 Porto Velho, RO, BrazilUAGRM, IRD, IIAP, LMI,EDIA, Montpellier, FranceINPA, Av Andre Araujo 2936, BR-69067375 Manaus, AM, BrazilUniv Fed Alagoas UFAL, Av Lourival Melo Mota,S-N Tabuleiro Martins, BR-57072900 Maceio, AL, BrazilUniv Fed Sao Paulo, Rua Doutor Carvalho Mendonca 144, BR-11070100 Santos, SP, BrazilUniv Fed Amazonas, Av Gen Rodrigo Octavio Jordao Ramos 3000, BR-69077000 Manaus, AM, BrazilIIAP, Vv Jose Quinones Km 2-5,Apartado Postal 784, Iquitos, PeruIRD, UMR BOREA, MNHN, CNRS 7208,SU,UCN,UA,IRD 207, Ave Agropolis 911, F-34394 Montpellier, FranceUMSS, ULRA, FAUNAGUA, ECOSINTEGRALES SRL, Ave Max Fernandez Final S-N, Cochabamba, BoliviaECOSINTEGRALES SRL, Res Act, Carlos Muller St 211, Cochabamba, Cercado, BoliviaInst Amazon Invest Cient SINCHI, Ave Vasquez Cobo Entre Calles 15 & 16, Bogota, ColombiaUniv Fed Sao Paulo, Rua Doutor Carvalho Mendonca 144, BR-11070100 Santos, SP, BrazilCAPES [1402376, 047/2012, 6632/14-9]CNPq [204344/2015-8][PAREV/FAPEAM 019/2010]FAPESP [2016/07910-0]Web of Scienc

Rarity of monodominance in hyperdiverse Amazonian forests.

Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors

Genetic landscape of 6089 inherited retinal dystrophies affected cases in Spain and their therapeutic and extended epidemiological implications

Inherited retinal diseases (IRDs), defined by dysfunction or progressive loss of photoreceptors, are disorders characterized by elevated heterogeneity, both at the clinical and genetic levels. Our main goal was to address the genetic landscape of IRD in the largest cohort of Spanish patients reported to date. A retrospective hospital-based cross-sectional study was carried out on 6089 IRD affected individuals (from 4403 unrelated families), referred for genetic testing from all the Spanish autonomous communities. Clinical, demographic and familiar data were collected from each patient, including family pedigree, age of appearance of visual symptoms, presence of any systemic findings and geographical origin. Genetic studies were performed to the 3951 families with available DNA using different molecular techniques. Overall, 53.2% (2100/3951) of the studied families were genetically characterized, and 1549 different likely causative variants in 142 genes were identified. The most common phenotype encountered is retinitis pigmentosa (RP) (55.6% of families, 2447/4403). The most recurrently mutated genes were PRPH2, ABCA4 and RS1 in autosomal dominant (AD), autosomal recessive (AR) and X-linked (XL) NON-RP cases, respectively; RHO, USH2A and RPGR in AD, AR and XL for non-syndromic RP; and USH2A and MYO7A in syndromic IRD. Pathogenic variants c.3386G > T (p.Arg1129Leu) in ABCA4 and c.2276G > T (p.Cys759Phe) in USH2A were the most frequent variants identified. Our study provides the general landscape for IRD in Spain, reporting the largest cohort ever presented. Our results have important implications for genetic diagnosis, counselling and new therapeutic strategies to both the Spanish population and other related populations.This work was supported by the Instituto de Salud Carlos III (ISCIII) of the Spanish Ministry of Health (FIS; PI16/00425 and PI19/00321), Centro de Investigación Biomédica en Red Enfermedades Raras (CIBERER, 06/07/0036), IIS-FJD BioBank (PT13/0010/0012), Comunidad de Madrid (CAM, RAREGenomics Project, B2017/BMD-3721), European Regional Development Fund (FEDER), the Organización Nacional de Ciegos Españoles (ONCE), Fundación Ramón Areces, Fundación Conchita Rábago and the University Chair UAM-IIS-FJD of Genomic Medicine.
