摘要: Although MR contrast agents are safe, adverse reactions occur. Many centers have not adopted policies for the management of patients at increased risk.关键词: anaphylaxis and allergy contrast media, toxicity gadolinium magnetic resonance (MR), contrast agents ...
Iodinated contrast agents (ICAs) may present with adverse reactions (ARs) to ICAs that are classified into general and organ-specific, such as contrast-induced nephropathy and encephalopathy. General ARs are further classified as acute (occurring within
There has been much less work on developing algorithms in individuals of African ancestry than in other populations [57]. A systematic review has shown that variants which are more prevalent in Black Africans have functional effects which are equivalent to those seen in White individuals [58], ye...
Atom-to-atom mapping (AAM) is a task of identifying the position of each atom in the molecules before and after a chemical reaction, which is important for understanding the reaction mechanism. As more machine learning (ML) models were developed for retr
Objectives: Hypersensitivity reactions (HSRs) are uncommon but serious adverse events following the administration of iodinated contrast media (ICM) prior to CT imaging. While premedication is almost universally given in high-risk patients, there is a lack of evidence regarding the efficacy of such ...
Bees, in contrast, have different eating habits, which interfere very little with people’s lifestyles. Their behaviour is much less aggressive unless they or their hives are disturbed [21]. Hornet nests are similar to wasp nests. They build their nests out of a pulp material primarily made ...
valenceelectronscan be drawn for amoleculeor ion, it means that its valence electrons are delocalized, or spread over more than twoatoms. This phenomenon is calledresonance, and the structures are called resonance forms. A double-headed arrow is used to show that the two or more structures ...
neutrons break free of the nucleus and bombard other nuclei which creates a chain reaction unless another material is present to absorb the extra neutrons. A chain reaction is an ongoing series of fission reactions. This can cause billions of reactions to occur in each second, resulting in the...
For the aziridination to β-substituted styrene derivatives the expected behavior [17] was observed that starting from the trans derivatives leads to pure trans products. In contrast, from the cis derivative a mixture of both isomers is obtained. Both catalysts have an overall good activity in ...
