We study the effects of rounding on moments random variables. Specifically, given a variable X and its rounded counterpart rd(X), we study|E[Xk]-E[rd(X)k]|for non-negative integer k. consider case that function rd: R → F corresponds either to (i) nearest point in some discrete set or (ii) randomly larger smaller this same with probabilities proportional distances these points. In both cases, sh...

OBJECTIVE To investigate the incidence and risk factors for retinal detachment (RD) after cataract surgery or refractive lens exchange (RLE) in patients aged below 61 years. METHODS Retrospective medical chart review of 7,886 patients (13,925 eyes) who underwent cataract surgery or RLE. Patients aged below 61 years were selected. Age, gender, axial length, follow-up times, and the occurrence ...

background and objectives: to investigate coagulase gene polymorphisms of mrsa and mssa isolates from shiraz teaching hospitals from 2011 to 2012. materials and methods: a total of 302 isolates of staphylococcus aureus were collected from clinical specimens in three major teaching hospitals and confirmed on the basis of morphological characteristics and biochemical tests. the isolates were subj...

We investigated the effects of photoreceptor degeneration on the anatomy and physiology of inner retinal neurons in a mouse model of retinitis pigmentosa, the retinal degeneration (rd) mutant mouse. Although there is a general assumption that the inner retinal cells do not suffer from photoreceptor death, we confirmed major changes both accompanying and after this process. Changes include sprou...

This is a brief review of data obtained by analyzing the morphology and the physiology of the retinas in rd/rd and normal, wt mice, aged 10-90 days. Second-order neurons of the rd/rd show abnormalities that start with the anomalous development of rod bipolar cells around P10 and culminate with the atrophy of dendrites in cone bipolar cells, mostly evident at P90. Horizontal cells remodel consid...

background and objectives: bacillus anthracis is one of the most homogenous bacteria ever described. bacillus anthracis 17jb is a laboratory strain. it is broadly used as a challenge strain in guinea pigs for potency test of anthrax vaccine. material and methods: this work describes genetic characterization of b. anthracis 17 jb strain using the snps and mlva genotyping. results and conclusion:...

conclusions sequence and structural diversity of the 3'utr variable region and poly u/uc region found in the local isolates indicate specificity in the regulating elements of 3'utr that might be associated with differential replication efficacy of the hcv pakistani isolates. the study necessitates functional characterization of these regulating elements to elucidate variable viral eff...

conclusions the results of this study showed that pcr–rflp technique was a fast and applicable method especially for separation, detection and differentiation between species of b. melitensis and b. abortus biovars in blood sample. also the presented data showed that b. melitensis biovar 1 was the prevalence biovar. background brucella is an intracellular parasite of the disease brucellosis thr...

To determine the effects of the recessive retinal degeneration (rd) gene on behavioral performance, three Alzheimer's transgenic lines (APPsw, P301L, APPsw + P301L) and non-transgenic littermates were evaluated in a comprehensive behavioral battery between 5 and 8.5 months of age. For all four genotypes collectively, rd homozygosity resulted in profound impairment in spatial cognitive tasks req...
