statement of the problem diagnosis of periodontal diseases without any accurate radiograph is inadequate. bitewing (bw) and periapical (pa) radiographic techniques are commonly used to assess alveolar bone crest (abc) level which is crucial in the evaluation of periodontal disease. purpose the purpose of this study was to compare the precision of bw and pa radiographs in determining the distanc...

Some pts with functional dyspepsia (FD) present with delayed gastric emptying (GE). The association between this digestive motor abnormality and dyspeptic symptoms has never been investigated in a large FD population. We prospectively evaluated clinical features, dyspeptic symptoms and GE of solids in 296 strictly selected FD pts (118 M, 178 F; 39 ± 12 yrs; 62 ± 12 kg; m : SD). Epigastric pain ...

in this study, the effect of cognitive load (cl) training on duration and accuracy of bimanual coordination (bc) task was investigated. for this purpose, athletic male students of shiraz university were randomly divided into 4 groups: g1 with low cl, g2 with intermediate cl, g3 with high cl and g4 control. the subjects practiced for 6 weeks, 3 sessions a week, 6 blocks, 12 trials. the subjects ...

A 14-d study was conducted to evaluate the effects of cultured aflatoxin B1 (AFB1) on performance, serum biochemistry, serum natural antibody and complement activity, and hepatic gene expression parameters in Pekin ducklings. A total of 144 male Pekin ducklings were weighed, tagged, and randomly allotted to 4 dietary treatments containing 4 concentrations of AFB1 (0, 0.11, 0.14, and 0.21 mg/kg)...

Selection was applied from 1964 to 1978 for increased weaning weight (WWL) or yearling weight (YWL) in two Hereford lines. An Angus line was maintained as an unselected control line (CL). Each line was maintained with 50 cows and four sires each year (two sires selected each year and used for 2 yr). Primary traits measured in the lines were birth weight (BW), preweaning daily gain (WDG), weanin...

the objective of this study was to investigate the effect of birth weight (bw) on future milk production and reproductive performance in iranian holstein cattle. records of holstein cows between 1967 and 2010 were obtained from the animal breeding center of iran. birth weights within each herd were grouped into five categories based on the standard normal distribution curves (z ≤-0.8416, -0.841...

A study was carried out to investigate the sodium requirements of broiler chicks in the first week post-hatching using diets with two dietary electrolyte balances (DEB). During the first week, birds were given feeds with four levels of total sodium (0.12, 0.24, 0.36, and 0.48%) and two DEB (Na+ + K+ − Cl− = 160 or 240 mEq/kg). Feeds given thereafter to 42 d had common formulation. Both sodium a...

INTRODUCTION In septic patients, an unpredictable response to epinephrine may be due to pharmacodynamic factors or to non-linear pharmacokinetics. The purpose of this study was to investigate the pharmacokinetics of epinephrine and its determinants in patients with septic shock. METHODS Thirty-eight consecutive adult patients with septic shock were prospectively recruited immediately before e...

OBJECTIVES To determine the pharmacokinetic parameters of gentamicin in a population of 200 premature newborns and to investigate the influence of several clinical and physiopathological covariates on the pharmacokinetics of the drug. To validate the pharmacokinetic analysis performed in another population of 50 premature newborns. METHODS A total of 200 premature newborns were evaluated at t...
