Abstract:
It has been suggested that the potential for thrombo-embolic complications is greater with the use of non-ionic contrast agents than with ionic contrast agents. The increasing use of interventional therapy in patients with acute coronary disease makes the discussion of a possible relationship between thrombo-embolic complications and use of non-ionic contrast media pertinent. It has been shown that ionic contrast media have a marked effect on the coagulation system and platelet function. The non-ionic contrast media have a less pronounced effect on the coagulation system and platelet function

Angiographic contrast media (CM) may cause both vasodilatation and vasoconstriction, effects that can only be partly be explained by the media's hyperosmolality. The present study describes a CM-induced vasoconstriction of isolated rabbit coronary arteries that depends on chemotoxicity and ion content of the CM. Rings of arteries were mounted in tissue baths and the constrictions induced by different CM were measured. Iotrolan and iodixanol (nonionic dimers) caused the most powerful constrictions followed by iohexol (non-ionic monomer) and mannitol. Ioxaglate (ionic dimer) and diatrizoate (ion

While noir and woman's film used expressive techniques to emphasize the split nature of the human psyche—the opposition between conscious and unconscious realities—1950s musical goes one step further.

However, U.S. news followed, and even continued in digital venues, the century-spanning trend of growing longer.

Abstract Oxygen ingress in H2S media is often the cause of serious corrosion which is extremely difficult to inhibit. Potential-pH diagrams show that in acidic media in which H2S predominates, the introduction of traces of oxygen generally leads to the formation of thiosulfates in solution. However, in the presence of H2S this intermediate oxidation product has little effect on the corrosivity. An H2S atmosphere slightly contaminated with oxygen is therefore not necessarily corrosive, particularly in the presence of buffered waters.

These non-biodegradable, potentially carcinogenic metals pose serious health risks in drinking water. This study developed an efficient aqueous biphasic system (ABS) for removing these metals using real drinking water samples. Two ionic liquids, tetrabutylphosphonium DTPA ([TBP][DTPA]) and tetrabutylphosphonium acetate ([TBP][Ac]), were selected as ABS components, with ammonium sulfate as the salting-out agent. Phase dia

Abstract:
Using a legally obtained dataset of 34 copyrighted O’Reilly Media books, we apply the DE-COP membership inference attack method to investigate whether OpenAI’s large language models were trained on copyrighted content without consent. Our AUROC scores show that GPT-4o, OpenAI’s more recent and capable model, demonstrates strong recognition of paywalled O’Reilly book content (AUROC = 82%), compared to OpenAI’s earlier model GPT-3.5 Turbo. In contrast, GPT-3.5 Turbo shows greater relative recognition of publicly accessible O’Reilly book samples. GPT-4o Mini, as a much smaller model, shows no kno

Abstract:
The purpose of this report is to compare the risk communication strategies and public health mitigation measures implemented by Germany, Norway, Sweden, Switzerland, and the United Kingdom (UK) in 2020 in response to the COVID-19 pandemic based on publicly available documents. The report compares the country responses both in relation to one another and to the recommendations and guidance of the World Health Organization where available. The comparative report is an output of Work Package 1 from the research project PAN-FIGHT (Fighting pandemics with enhanced risk communication: Messages, comp
