the purpose of this study was to investigate the hypothesis weather the combination of lead acetate and deltamethrin can enhance avian toxic effects produced by lead exposure only. overall, 48 japanese quails, coturnix coturnix japonica (15 day old) were randomly divided into 4 experimental groups of 12 birds each and sex ratio of 1:1. experimental groups consisted of control japanese quails, b...

keloids are aesthetically disfiguring and severely disabling. the optimal treatment remains undefined. this clinical study, evaluate the efficacy and side effects of combined topical silicone and 5-fluorouracil on the prevention of keloids. in this double blind randomized clinical trial, fifty patients with keloids were randomly allocated in two groups. the control group were treated by periles...

ABSTRACT Introduction: Apelin and resistin as novel adipokines have insulin-sensitizing effects, which may be associated with decreased blood glucose concentration. In this study, we aimed to investigate the impact of combined exercise training on plasma concentrations of apelin, resistin and insulin resistance in patients with type 2 diabetics male (T2D). Methods: In a quasi-...

Let the mixed linear regression model when mean value parameters satisfy some linear constraints be under consideration. To detect rough errors or mistakes (outliers) in observations needs a knowledge of a covariance matrix of an observation vector. If unknown variance components occur in it, some problems arise how to recognize, whether estimates or approximations of them can be used instead o...

The Government and its agencies have seriously overestimated the impact of the specialist schools programme on educational attainment. The substantially higher exam scores achieved on average by schools with specialist status are due primarily to sample selection bias and not to any benefits flowing from subject specialisation itself. A fixed effects model is used on the panel of maintained sec...

The effects of including incoherent (bound-electron) and coherent (Rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (E?) range of 40 keV to 3 MeV. Incoherent scattering decreases the values of these factors in both layers up to E? ~ 200 keV and the effect i...

This study examines the relation of language arts instruction to students’ letter-word reading skill growth from the beginning of 1st grade to the end of 2nd grade using cross-classified random effects models. Amounts of teacher-managed, code-focused instruction in 1st and 2nd grade each uniquely predicted students’ letter-word reading skill growth; plus, there were child-by-instruction interac...

Control of wildlife pest populations by infectious recombinant virus, expressing genes for specific sterilization could be more effective than conventional reproductive antigens. Using the rabbit, I describe the mortality agents, provided that two conditions are met: research required to test the concept and discuss the legal 111 the endocrine function of affected animals is not and ethical con...
