We examined faecal egg count reduction tests (FECRTs) conducted with hookworm-infected humans in Ghana in 2007 (study 1) and 2010 (study 2) in order to explore aspects of the test analysis. Some subjects showed increased FEC following drug treatment. This occurred mostly in <150 epg pre-treatment FEC subjects. We sought a means to remove 'erroneous' negative drug efficacy cases from the FECRT a...

Log-linear-binomial distribution was introduced for describing the behavior of the sum of dependent Bernoulli random variables. The distribution is a generalization of binomial distribution that allows construction of a broad class of distributions. In this paper, we consider the problem of estimating the two parameters of log-linearbinomial distribution by moment and maximum likelihood methods...

We consider a random network evolving in continuous time in which new nodes are born and old may die, and where undirected edges between nodes are created randomly and may also disappear. The node population is Markovian and so is the creation and deletion of edges, given the node population. Each node is equipped with a random social index and the intensity at which a node creates new edges is...

Methods for interval estimation of the ratio of two independent coefficients of variation (CVs) of the delta-lognormal distribution are proposed based on the concept of the generalized variable approach (GPA) and the method of variance estimates recovery (MOVER). The performances of both methods are assessed through Monte Carlo simulation in terms of the coverage probabilities and average lengths.

this experiment was conducted to determine the effects of the oral consumption of guggulplant resin on the performance and humoral immunity response of broiler chicks. for doing this experiment, 320 one-day old chicks of the cobb 500 strains, in a completely randomized design with 4 treatments and 4 replicates were used. experimental diets include: control diet (without the guggul), control die...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

this paper presents a 54-year-old female with lupus whom severe anaemia due to pure red cell aplasia (prca) was the first manifestation. there was seven years interval between prca onset and diagnosis of lupus. thymectomy due to thymoma had been carried out six years before but anaemia sustained. hypothyroidism and hypoparathyroidism were other associated diseases. severe anaemia and the need f...

INTRODUCTION AND OBJECTIVES Red blood cell distribution width has emerged as a new prognostic biomarker in cardiovascular diseases. Its additional value in risk stratification of patients with chronic heart failure has not yet been established. METHODS A total of 698 consecutive outpatients with chronic heart failure were studied (median age 71 years [interquartile range, 62-77], 63% male, le...
