BACKGROUND Some dietary factors have been associated with the risk of type 1 diabetes in childhood. OBJECTIVE We investigated relations between dietary energy from major food groups and incidence of childhood type 1 diabetes by using an ecologic study design. DESIGN We conducted univariate and multivariate regression analysis with incidence rates of type 1 diabetes in the late 1980s and ear...

Let G be a simple graph with vertex set V(G) {v1,v2 ,...vn} . For every vertex i v , ( ) i  v represents the degree of vertex i v . The h-th order of Randić index, h R is defined as the sum of terms 1 2 1 1 ( ), ( )... ( ) i i ih  v  v  v  over all paths of length h contained (as sub graphs) in G . In this paper , some bounds for higher Randić index and a method for computing the higher R...

An Euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix M = [dij], where for ij, dij is the Euclidean distance between the nuclei i and j. In this matrix dii can be taken as zero if all the nuclei are equivalent. Otherwise, one may introduce different weights for distinct nuclei. Balaban introduced some monster graphs and then Randic computed complexit...

in this paper we carried out an exact statistics on the basis of total admission due to abortions, with following results: 1- abortion incidence is 14 of total admissions. 2- 46.8 of abortions were between the 8th and 12th weeks of gestation. 3- 42,038 of the patients with abortion were 24 years old or younger (younger than 25 years of age). 4- the abortion incidence is equal in different blood...

background rabies has been reported as the most important endemic zoonotic disease in iran and still remains as a major public health problem. objectives the main objective of the current research was to study the epidemiology of animal bites in borujerd county in iran and to compare its prevalence to other parts of iran from april 2006 to september 2011. patients and methods the data were reco...

pseudomembrane colitis (pmc) and antibiotic associated colitis (aac) are acute disease of the colon. in the case of in adequate treatment, the disease will often become chronic and my lead to the dysplasia of the epithelial cells of the infected areas. previously because of poor knowledge. treatment in this case, one of the method for treatment was surgical ablation of the large intestine while...

background: to manage relapsing‑remitting multiple sclerosis (ms) in the course of acute exacerbations, methylprednisolone (mp) (medrol or solu‑medrol), has the ability to lock the injured blood‑brain barrier and decrease irritation in the central nervous system. the aim of this preliminary study was to investigate the frequency and time interval related to mp pulse therapy in patients with ms....

conclusions according to the results obtained, the largest numbers of deaths and illnesses were due to the high average pm10 concentration or an increase in the number of days of exposure to this pollutant. background particulate matters have harmful effects on human health and can intensify mortality and disease. objectives the purpose of this study was to evaluate the health impacts of partic...

QSAR study has been carried out on the CDK2 inhibitory activity of 6-substituted 2-arylaminopurines in 0D- to 2D-Dragon descriptors. The derived models have revealed that reciprocal hyper-detour index (descriptor Rww) and path/walk 5 Randic shape PW5) played a pivotal role rationalization inhibition titled compounds. Molecular weight (MW), mean atomic volume scaled Carbon atom (Mv) properties s...
