Background: Growth retardation is a long-term complication in pediatric transfusion-dependent thalassemias (TDTs), presented as short-stature and upper body segment shortening. The cause of this condition was chronic hypoxia, iron overload, endocrinopathy, inadequate transfusion, and iron chelation. We analyze the relationship between ferritin level and growth status of pediatric TDTs. Methods...

background: recently, some new nanobiosensors using different nanoparticles or microarray systems for detection of mycotoxins have been designed . however, rapid, sensitive and early detection of aflatoxicosis would be very helpful to distinguish high-risk persons.objectives: we report a highly sensitive competitive immunoassay using magnetic/silica core shell as a signal intensifier for the de...

Let $G$ be a simple graph of order $n$ and size $m$.The edge covering of $G$ is a set of edges such that every vertex of $G$ is incident to at least one edge of the set. The edge cover polynomial of $G$ is the polynomial$E(G,x)=sum_{i=rho(G)}^{m} e(G,i) x^{i}$,where $e(G,i)$ is the number of edge coverings of $G$ of size $i$, and$rho(G)$ is the edge covering number of $G$. In this paper we stud...

patients and methods this cross-sectional study included a total of 120 adult predialysis ckd patients. forty patients were allocated in each predialysis ckd group of stages 3, 4, and 5. serum ctnt and hs-crp, plasma nt-probnp, and single spot urine albumin creatinine ratio (acr) were measured. ultrasonographic examination of carotid artery was done with 7.5 mhz linear probe in b mode ultrasono...

Background: Katz Index is a well-known index for assessing basic activities of daily living. The aim was to determine validity and reliability of the Katz Index in Iranian patients with acute stroke. Methods: Eighty-seven patients (56 male, 31 female) with acute stroke (1-30 days post-stroke) participated in this psychometric properties study. Interval time for retest was 14 days. All partic...
