Introduction: In this study, organ radiation doses were calculated for the renal agent 99mTc-DTPA in children. Bio-kinetic energy of 99mTc-DTPA was evaluated by scintigraphy and estimates for absorbed radiation dose were provided using standard medical internal radiation dosimetry (MIRD) techniques.Material and Methods: In this applied research, fourteen children patients (6 males and 8 females...
The rates of oxidation of four chelating agents with Ce(IV) in HC104 solutions, have been studied by the stopped-flow technique. The rates first increase with increasing acidity, reach maxima which are characteristic of the chelating agent and the medium, then progressively decrease with further increasing acid concentration. At their maximum reactivities, the tendencies for oxidation decrease ...
BACKGROUND Pertussis occurs in older children, adolescents and adults due to waning immunity after primary vaccination. Booster vaccination for pre-school children has been recommended in Italy since 1999. In this study (NCT00871000), the immunogenicity, safety and reactogenicity of a booster dose of reduced-antigen content diphtheria-tetanus-acellular pertussis-inactivated poliovirus vaccine (...
مصرف لجن فاضلاب با غلظت های بالای فلزات سنگین ، غلظت این عناصر را در خاک، آب های زیرزمینی و زنجیره غذایی افزایش می دهد. در این تحقیق اثر لجن فاضلاب و کلرید کادمیوم بر غلظت کادمیوم و انتقال این عنصردر خاک و جذب آن به وسیله گیاه مورد بررسی قرار گرفته است. لجن فاضلاب شهری به میزان 50 تن در هکتار به همراه کلرید کادمیوم با غلظت های صفر، 5/42 و 85 میلی گرم کادمیوم در کیلوگرم بر اساس وزن خشک لجن در ق...
We report two cases of focal nodular hyperplasia in patients following gadoxetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging confirmed with histopathology. These cases showed an atypical pattern during the delayed-hepatobiliary phase after the injection of gadoxetic acid. One case showed a total defect, and the other showed a peripheral ring-like enhancement without a visible central...
Abstract This review concerns the speciation of protactinium in aqueous solution under its both oxidation states +IV and +V. Emphasis is placed on experimental data obtained at trace level but also macroscopic amount leading to determination thermodynamic structural data. Thus, complexation Pa(V) with mineral acids organic acids, mainly polyaminocarboxylic (iminodiacetic acid [IDA], nitrilotria...
Biomarkers providing in vivo quantification of the basic elements of cystic fibrosis (CF) lung disease are needed. A study was performed to determine whether the absorption of a small radiolabelled hydrophilic molecule (Indium-111 (In-)DTPA) would be increased in CF airways. DTPA clearance has been used previously to assess epithelial permeability and may also be useful for quantifying liquid a...
BACKGROUND AND OBJECTIVES High-frequency chest wall oscillation (HFCWO) has been shown to be as effective as standard chest physiotherapy (SCPT) for removal of pulmonary secretions as well as increasing FEV(1) in cystic fibrosis (CF) patients. Patients using HFCWO often administer aerosolized medications simultaneously, reducing time required for daily care. While peripheral pulmonary distribut...
Sol-gel technology is a versatile tool for preparation of complex silica-based materials with targeting functions for use as adsorbents in water purification. Most efficient removal of organic pollutants is achieved by using enzymatic reagents grafted on nano-carriers. However, enzymes are easily deactivated in the presence of heavy metal cations. In this work, we avoided inactivation of immobi...
OBJECTIVES To assess the differences between normal and cirrhotic livers by means of T1 mapping of liver parenchyma on gadoxetic acid (Gd-EOB-DTPA)-enhanced 3 Tesla (3T) MR imaging (MRI). METHODS 162 patients with normal (n = 96) and cirrhotic livers (n = 66; Child-Pugh class A, n = 30; B, n = 28; C, n = 8) underwent Gd-EOB-DTPA-enhanced 3T MRI. To obtain T1 maps, two TurboFLASH sequences (TI...
