purpose: to assess the effect and long-term results of oral propranolol in pediatric capillary hemangiomas. methods: four children aged 3 months to 5 years with periocular and orbital hemangioma of infancy (hoi) were treated with propranolol, 2 milligram per kilogram per day divided in 2 doses. propranolol was continued in all cases until the end of the first year of life and tapered over 2-3 w...

multiple sclerosis (ms) is one of the autoimmune diseases with an unknown cause. the aim of this study was to explore the link between air quality and ms relapses in patients who suffer from ms.this time-series study was conducted on patients registered at the iranian multiple sclerosis society in 2011-2012. they were randomly selected from patients lived in tehran in the last five years, and h...

in this paper, under the condition that $k$ is concave, we characterize lacunary series in $q_{k}$ spaces. we improve a result due to h. wulan and k. zhu.

background and objective: scorpion sting and snakebite are the important problems in some area such as iran that must be addressed. this study was to investigate temporal pattern of scorpion sting and snakebite incidence in patients referred to masjedsoleiman’s main hospital, during 24 months from 21 march 2008 to 20 march 2009. materials and methods: it was an analytical study to scrutiny of m...

Inflationary models whose vacuum energy arises from a D-term are believed not to suffer from the supergravity eta problem of F-term inflation. That is, D-term models have the desirable property that the inflaton mass can naturally remain much smaller than the Hubble scale. We observe that this advantage is lost in models based on string compactifications whose volume is stabilized by a nonpertu...

En 1965 Lotfi Zadeh propuso un procedimiento para evitar los círculos viciosos en sí mismos paradójicos, que habían provocado la crisis de fundamentos de la teoría de conjuntos. Dada la imposibilidad de aportar un procedimiento axiomático capaz de evitarlos, se optó por intentar neutralizar esta situación por un recurso de tipo práctico, como fue la formalización de los conjuntos borrosos o imp...

String compactifications with non-abelian gauge fields localized on D-branes, with background NSNS and RR 3-form fluxes, and with non-trivial warp factors, can naturally exist within T-dual versions of type I string theory. We develop a systematic procedure to construct the effective bosonic Lagrangian of type I T-dualized along a six-torus, including the coupling to gauge multiplets on D3-bran...

in this paper, we will compare a homotopy perturbation algorithm and taylor series expansin method for a system of second kind fredholm integral equations. an application of he’s homotopy perturbation method is applied to solve the system of fredholm integral equations. taylor series expansin method reduce the system of integral equations to a linear system of ordinary differential equation.

Background: In the past 20 years, a dramatic improvement in the prognosis of patients with hepatoblastoma (HB)has been achieved by combining surgery and chemotherapy in several national and international trials.Materials and Methods: Four children ( 3 girl and 1 boy) aged 34 days, 4 months, 13 months, and 1 year with meanage of 6.53 (±5.15) months were presented to our center from 2002 to 2009 ...
