1Is glucose-6-phosphate dehydrogenase deficiency more prevalent in Carrion's disease endemic areas in Latin America?显示文摘Glucose-6-phosphate dehydrogenase(G6PD) is a cytoplasmic enzyme with an important function in cell oxidative damage prevention.Erythrocytes have a predisposition towards oxidized environments due to their lack of mitochondria,giving G6 PD a major role in its stability.G6 PD deficiency(G6PDd) is the most common enzyme deficiency in humans:it affects approximately 400 million individuals worldwide.The overall G6 PDd allele frequency across malaria endemic countries is estimated to be 8%.corresponding to approximately 220 million males and 133 million females.However,there are no reports on the prevalence of G6 PDd in Andean communities where bartonellosis is prevalent.Fernando Mazulis Claudia Weilg Carlos Alva-Urcia Maria J.Pons Juana del Valle Mendoza 2015Asian Pacific Journal of Tropical Medicine2015,8,12:2
2Liouvillian and Analytic Integrability of the Quadratic Vector Fields Having an Invariant Ellipse显示文摘We characterize the Liouvillian and analytic integrability of the quadratic polynomial vector fields in R2 having an invariant ellipse.More precisely,a quadratic system having an invariant ellipse can be written into the form x=x2+y2-1+y(ax+by+c),y=x(ax+by+c),and the ellipse becomes x2+y2=1.We prove that(i) this quadratic system is analytic integrable if and only if a=0;(ii) if x2+y2=1 is a periodic orbit,then this quadratic system is Liouvillian integrable if and only if x2+y2=1 is not a limit cycle;and(iii) if x2+y2=1 is not a periodic orbit,then this quadratic system is Liouvilian integrable if and only if a=0.Jaume LLIBRE Claudia VALLS 2014Acta Mathematica Sinica,English Series2014,30,3:2

10Seronegative disseminated Bartonella spp. infection in an immunocompromised patient显示文摘An 11 year old, hispanic girl with a history of B-cell acute lymphoblastic leukemia was admitted to the hospital for symptoms compatible with Bartonella henselae infection. The first molecularly diagnosed case of disseminated Bartonella henselae infection was reported in an immunocompromised patient in Lima, Peru. The analysis was confirmed by Polymerase Chain Reaction and automated sequencing of a liver biopsy sample, even though the serologic tests were negative. In conclusion, Bartonella spp. infection should have a particular diagnostic consideration in immunocompromised patients with fever of unknown origin and further investigation regarding the patient's past exposures with cats should also be elicited.Claudia Weilg Olguita Del Aguila Fernando Mazulis Wilmer Silva-Caso Carlos Alva-Urcia Rosario Cerpa-Polar Erick Mattos-Villena Juana Del Valle Mendoza 2016Asian Pacific Journal of Tropical Medicine2016,9,12:0
11Weierstrass Integrability of Complex Differential Equations显示文摘We characterize the complex differential equations of the form dy/dx=a_(n)(x)y^)n_+a_(n-1)(x)y^(n-1)+…+a_(1)(x)y+a_(0)(x) where a_(j)(x) are meromorphic functions in the variable x for j = 0,..., n that admit either a Weierstrass first integral or a Weierstrass inverse integrating factor.Jaume LLIBRE Claudia VALLS 2021Acta Mathematica Sinica,English Series2021,37,10:0

13Wnt genes in colonic polyposis predisposition显示文摘Much of the genetic predisposition to polyposis,and particularly to serrated polyposis(SP),remains unknown.Only germline pathogenic variants in RNF43,a tumor suppressor that exerts negative feedback in the Wnt/β-catenin signaling pathway,have been causally linked to some SP cases(<2%),a disease associated with increased risk of colorectal cancer(CRC).^(1) Most known hereditary CRC and polyposis genes affect DNA repair,BMP/TGF-β,or Wnt signaling,being the latter associated with adenomatous and serrated polyposis phenotypes.2 Based on this observation,we evaluated the presence and role of germline variants in those pathways in unsolved polyposis patients.Isabel Quintana Mariona Terradas Pilar Mur Iris B.A.Wte Paske Sophia Peters Isabel Spier Verena Steinke-Lange Claudia Maestro David Torrents Montserrat Puiggròs Romina Royo Raul Tonda Genís Parra Davide Piscia Sergi Beltrán Matilde Navarro Virginia Piñol Joan Brunet Noemi Gonzalez-Abuin Gemma Aiza Anna Sommer Yasmijn van Herwaarden Galuh Astuti Elke Holinski-Feder Nicoline Hoogerbrugge Richarda Mde Voer Stefan Aretz Gabriel Capellá Laura Valle 2023Genes & Diseases2023,10,3:0
14PHASE PORTRAITS OF THE LESLIE-GOWER SYSTEM显示文摘In this paper we characterize the phase portraits of the Leslie-Gower model for competition among species.We give the complete description of their phase portraits in the Poincarédisc(i.e.,in the compactification of R^(2) adding the circle S1 of the infinity)modulo topological equivalence.It is well-known that the equilibrium point of the Leslie-Gower model in the interior of the positive quadrant is a global attractor in this open quadrant,and in this paper we characterize where the orbits attracted by this equilibrium born.Jaume LLIBRE Claudia VALLS 2022Acta Mathematica Scientia2022,42,5:0
