Opera and poison : a secret and enjoyable approach to teaching and learning chemistry [PDF]

, 2013
The storyline of operas, with historical or fictional characters, often include potions and poisons. This has prompted a study of the chemistry behind some operatic plots.

Hydroxocobalamin. VI. Comparison of Intestinal Absorption in Man Of Large Doses of Hydroxocobalamin and Cyanocobalamin.

Experimental Biology and Medicine, 1966
SummaryIntestinal absorption of large oral doses of hydroxocobalamin and cyanocobalamin (100,. 500 and 1000 μg) was compared and quantitated in 17 normal subjects using a double label isotope technique.In 3 pairs of normal individuals, Co57-labeled cyanocobalamin and Co60-labeled hydroxocobalamin were administered simultaneously in oral doses of 100 ...

Hemodialysis Failure Secondary to Hydroxocobalamin Exposure [PDF]

Baylor University Medical Center Proceedings, 2017
Hydroxocobalamin is a recently approved antidote for the treatment of cyanide poisoning. The case presented involves a young patient administered empiric hydroxocobalamin due to suspected cyanide overdose. Due to the development of acute kidney injury and severe metabolic derangement, emergent hemodialysis was initiated. Unfortunately, hemodialysis was

Redirecting Intermediary Metabolism to Counteract Cyanide Poisoning

The FASEB Journal, Volume 39, Issue 12, 30 June 2025.
Cyanide is coined “the classic metabolic poison”; however, FDA‐approved cyanide chelators do not counteract cyanide's metabolic damage. Here, we review the mechanisms of cyanide toxicity, with a focus on intermediary metabolism. We present the theory that, within the innate plasticity of the metabolome, there may reside metabolic pathways that can ...

Site directed mutagenesis of L-pyrrolysine in dimethylamine methyltransferase [PDF]

, 2009
Methanosarcina barkeri is an archaeon and is able to use methylamines as growth substrates for methanogenesis. The methylamine methyltransferases that are involved in initiating methanogenesis from the methylamines have an in-frame amber codon (UAG) that

The Explanatory Indispensability of Memory Traces [PDF]

, 2020
During the first half of the twentieth century, many philosophers of memory opposed the postulation of memory traces based on the claim that a satisfactory account of remembering need not include references to causal processes involved in recollection ...

Gene identification for the cblD defect of vitamin B12 metabolism [PDF]

, 2008
Background Vitamin B12 (cobalamin) is an essential cofactor in several metabolic pathways. Intracellular conversion of cobalamin to its two coenzymes, adenosylcobalamin in mitochondria and methylcobalamin in the cytoplasm, is necessary for the ...

Evolutionary Trajectories of Methionine Metabolism in Mycobacterium and Its Application to Engineer a Vitamin B12 Whole‐Cell Ribosensor

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
Molecular and functional experiments highlight the relevance of species‐specific polymorphisms in a B12 riboswitch of the Mycobacterium genus. This information provided proof‐of‐concept to engineer a whole‐cell biosensor capable of detecting vitamin B12. ABSTRACT Vitamin B12 metabolism differs among members of the Mycobacterium genus.

Cyanide in breath as a marker for cyanide poisoning [PDF]

, 2011
Approximately 120 people die every year due to fires in Sweden. A majority of the fire victims die due to toxic fire gases. Carbon monoxide is often thought to be the major cause of death. Still, another very toxic fire gas, hydrogen cyanide, is formed

Concomitant use of metformin and proton pump inhibitors increases vitamin B12 deficiency risk in type 2 diabetes

Journal of Diabetes Investigation, Volume 16, Issue 6, Page 1020-1027, June 2025.
The concomitant use of metformin and PPI was significantly associated with an increased risk of vitamin B12 deficiency in patients with type 2 diabetes. ABSTRACT Introduction Vitamin B12 deficiency is one of the adverse drug reactions of metformin and proton pump inhibitors (PPIs).
