Effect on uptake of heavy metal ions by phosphate grafting of allophane

Journal of Colloid and Interface Science, 2005
The effect of phosphate grafting on the uptake of various heavy metal ions was investigated using allophane, a clay mineral having a chemical composition of 1-2SiO2Al2O3.5-6H2O with hollow nanoparticles 3.5-5 nm in size. Phosphate grafting was performed on allophane with an atomic ratio Si/Al=0.85 using the orthophosphates (NH4)2HPO4, Na2HPO4 and ...

Thermosensitive Poly(N-Isopropylacrylamide)-Grafted Magnetic-Cored Dendrimers for Benzene Uptake

SSRN Electronic Journal, 2022
A series of thermosensitive and magneto-responsive dendrimers was synthesized based on magnetic-cored dendrimers (MCD) and carboxylic end-capped poly(N-isopropylacrylamide) (PNIPAM) to obtain PNIPAM-g-MCD. Thermo-response profiles of the PNIPAM-g-MCD from dynamic light scattering within the temperature range of 25-45 °C indicated that the lower ...

The Significance of the Absence of ¹³¹ I-Hippuran Uptake by a Kidney Graft

Nephron, 2008
Anuria is a frequent complication during the immediate post-transplantation period in kidney transplant recipients. Radioisotopic studies with 13lI-Hippuran and 99mTc-pertechnetate allow correct differentiation between viable and non-viable grafts.

The uptake and transfer of radioactive compounds in axial grafts ofHydra

Development, 1972
ABSTRACTHydra littoralis and H. attenuata were labelled with 45Ca, 32PO4, or [3H]thymidine, either by exposing them to a medium containing the isotope or by injecting the isotope into their gut cavities. Various portions of labelled and unlabelled hydra were grafted together in diverse combinations, and the rate of transfer of radioactivity to the ...

Graft-induced reduction in [3H]dopamine uptake into the non-lesioned striatum

NeuroReport, 1995
The effect of intraventricular fetal mesencephalic grafts placed in the 6-hydroxydopamine (6-OHDA) lesioned striatum on [3H]dopamine (DA) uptake into synaptosomes was studied. Apomorphine (APO)- and amphetamine (AMPH)-induced rotational behaviour was continuously reduced by the grafts over 7 months. After this time, a non-significant increase in [3H]DA

Does glubran 2 improve the graft uptake in tympanoplasty? A retrospective study

European Archives of Oto-Rhino-Laryngology, 2014
Tympanoplasty is a common procedure in otolaryngology practice and several factors have been described to increase graft uptake. Independent of the technique and graft material, the revascularization process of the graft is related to patient factors as well as contact of the tympanic membrane remnant's edges with the graft material.

Ga-67 Uptake in Cutaneous Lesions of Graft-Versus-Host Disease

Clinical Nuclear Medicine, 2000
Acute graft-versus-host disease (GVHD) usually involves the skin, gastrointestinal tract, and liver. A 47-year-old woman with fever of unknown origin was referred for a Ga-67 scan. The study showed diffuse uptake of Ga-67 throughout the skin. Subsequently, a skin biopsy confirmed the diagnosis of acute GVHD.

Uptake of radiolabeled leukocytes in prosthetic graft infection.

Surgery, 1981
The utility of radionuclide labeled leukocytes in the demonstration of infection within vascular prostheses was examined. The infrarenal aorta was replaced with a 3 cm Dacron graft in 12 dogs. On the third postoperative day, six of the animals received an intravenous injection of 10(8) Staphylococcus aureus.
