Trends in coordination of rhenium organometallic complexes in the Protein Data Bank

IUCrJ, 2022
Radiopharmaceutical development has similar overall characteristics to any biomedical drug development requiring a compound's stability, aqueous solubility and selectivity to a specific disease site. However, organometallic complexes containing 188/186Re

Ethanol affects the absorption and tissue distribution of orally administered antigens in mice

Brazilian Archives of Biology and Technology, 2013
The aim of this work was to evaluate the effects of ethanol on the adsorption and tissue distribution of orally administered antigens in mice. Results showed that ethanol reduced the level of anti-ovalbumin IgA antibodies in intestinal fluid for the mice

Detection of silent reflux events by nuclear scintigraphy in healthy dogs

Journal of Veterinary Internal Medicine, 2020
Background Reflux and aspiration in people are associated with respiratory disease, whereas approximately 50% of healthy adults microaspirate without apparent consequence. In dogs, analogous information is lacking.

Radionuclide Methods in the Diagnosis of Sacroiliitis in Patients with Spondyloarthritis: An Update

Rambam Maimonides Medical Journal, 2016
Sacroiliitis, inflammation of the sacroiliac joint (SIJ), is the hallmark of ankylosing spondylitis and spondyloarthritis (SpA) in general. The arsenal of recommended diagnostic modalities for imaging of the SIJ is scanty and, in practice, includes only ...

An Investigation of Iodovanadinite Wasteforms for the Immobilisation of Radio-Iodine and Technetium

Ceramics, 2023
99Tc and 129I are two long-lived, highly soluble and mobile fission products that pose a long-term hazard. A proposed wasteform for the disposal of radio-iodine is iodovanadinite (Pb5(VO4)3I), an apatite-structured vanadate.

Study on Separation of Rhenium, a Surrogate Element of Fissiogenic Technetium, from Aqueous Matrices Using Ion-Selective Extraction Chromatographic Resins

Separations, 2023
Long-lived fissiogenic technetium, 99Tc (half-life, 2.11 × 105 yrs), is a byproduct of the 235U and 239Pu fission in nuclear reactors and is a major component in nuclear waste.
