abstract: on december 2010, the government of iran ended the decades-long subsidy program for bread and energy products and launched the targeted subsidy reform program that considerably raised prices of food products. the objective of the study was to measure welfare impacts of food price changes on iranian urban households between two survey data of 2009/10 and 2011/12 which were taken from i...

iran has experienced high food prices in recent years. this paper examines the welfare impacts of rising major food groups' prices on iranian urban households using quadratic almost ideal demand system (quaids) approach. the elasticity coefficients derived from quaids are used to estimate compensated variations (cv).the study uses iranian household expenditure and income survey (heis) raw data,...

BACKGROUND Heterogeneous ventilation in lungs of individuals with allergies, cigarette smokers, asthmatics and chronic obstructive pulmonary disease (COPD) patients has been demonstrated using imaging modalities such as positron emission tomography (PET), magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT). These individuals suffer from narrow and/or closed a...

Spatially explicit capture-recapture methods, used widely to estimate the abundance of large carnivores, allow for movement within home ranges during sampling. Probability of detection is a decreasing function of distance from the home range center, with one parameter for magnitude and another for spatial scale. Sex-based and other differences in home range size potentially cause heterogeneity ...

PURPOSE To assess the repeatability and reproducibility of dynamic corneal response parameters measured by the Corvis ST (Oculus, Wetzlar, Germany). METHODS One eye randomly selected from 32 healthy volunteers was examined by the Corvis ST. Three different devices were used in an alternated random order for taking three measurements at each device in each subject. Standard intraocular pressur...

BACKGROUND Cystatin C is a new interesting marker of glomerular filtration rate (GFR). However, data regarding its biological variance are scarce and conflicting. The ability of cystatin C to longitudinally follow renal function in patients therefore remains questionable. METHODS 12 healthy subjects (6 men and 6 women) were included in the final statistical analysis. Serum creatinine, plasma ...

1.5 and 3% of Maillard's reaction products (MRP), prepared by heating glycine and glucose, were incorporated ino a semi-synthetic diet. The diet was sterilized by irradiation. MRP caused a change in apparent absorption of calcium and magnesium in germfree (GF) and conventional (CV) rats. The absorption of these minerals was reduced in the small intestine of CV and GF, perhaps due to the action ...
