Side-streams are most often used as feed, landfilled, incinerated, or discharged into sewage. These disposal methods are far from perfect. Taking into account the composition of the side-streams, it seems that they should be used as raw materials for further processing, in accordance with the zero-waste policy and sustainable development.

Idiopathic recurrent pyoderma gangrenosum with cobalamin deficiency in a 62-year-old male: a case report
CONCLUSION: PG is a rare form of neutrophilic dermatosis that can be difficult to diagnose and treat. PG has a mixed nutritional deficiency and a history of ulcers. It is crucial to have a high degree of suspicion when making a diagnosis, as well as to look for associated diseases and start treatment as soon as possible.PMID:36923778 | PMC:PMC10010805 | DOI:10.1097/MS9.0000000000000253 (Source: Hand Surgery)

Seeing Red: Hydroxocobalamin and Result Interference
Intravenous high dose hydroxocobalamin (CyanoKit ®, BTG Pharmaceuticals, London, United Kingdom) is indicated for the treatment of cyanide toxicity.1 In the last 10 years, the nitric oxide scavenging properties of hydroxocobalamin have brought it to the forefront for use in the treatment of vasoplegia.1–3 Despite a lack of randomized evidence, many retrospective studies have demonstrated its value in this context, and hydroxocobalamin has a number of characteristics favorable to critically ill patients with vasoplegia including a lack of serotonergic activity or evidence of contributing to a hypercoagulable state. (Sour...

Structural basis for activation of cobalt-carbon bond and control of adenosyl radical in coenzyme B12 catalysis
Chembiochem. 2023 Mar 14:e202300021. doi: 10.1002/cbic.202300021. Online ahead of print.ABSTRACTAdenosylcobalamin (AdoCbl) or coenzyme B12 is a naturally occurring organometallic compound that serves as a cofactor for enzymes that catalyze intramolecular group-transfer reactions and ribonucleotide reduction in a wide variety of organisms from bacteria to animals. AdoCbl-dependent enzymes are radical enzymes and generate an adenosyl radical by homolysis of the coenzyme's cobalt-carbon (Co-C) bond for catalysis. How do the enzymes activate and cleave the Co-C bond to form the adenosyl radical? How do the enzymes utilize the ...

Vitamin B12 attenuates leukocyte inflammatory signature in COVID-19 via methyl-dependent changes in epigenetic markings
COVID-19 induces chromatin remodeling in host immune cells, and it had previously been shown that vitamin B12 downregulates some inflammatory genes via methyl-dependent epigenetic mechanisms. In this work, whole blood cultures from moderate or severe COVID-19 patients were used to assess the potential of B12 as adjuvant drug. The vitamin normalized the expression of a panel of inflammatory genes still dysregulated in the leukocytes despite glucocorticoid therapy during hospitalization. B12 also increased the flux of the sulfur amino acid pathway, that regulates the bioavailability of methyl. Accordingly, B12-induced downre...

Disturbances in folate or methionine metabolism have been identified in many individuals with ASD, suggesting that the folate–methionine cycle may play an essential role in the pathogenesis of autism. Thus, changes in...

Genetically predicted levels of folate, vitamin B12, and risk of autoimmune diseases: A Mendelian randomization study
ConclusionThe study provides convincing evidence for an inverse association between serum folate level and risk of vitiligo. Further studies are warranted to elucidate the possible association between vitamin B12 and risk of IBD. (Source: Frontiers in Immunology)

Molecules, Vol. 28, Pages 2544: Co-Encapsulation of Epigallocatechin-3-Gallate and Vitamin B12 in Zein Microstructures by Electrospinning/Electrospraying Technique
evinho EGCG is a catechin known for its antioxidant and anti-inflammatory characteristics. Vitamin B12 is an essential vitamin found in animal-derived products, and its deficiency may cause serious health problems such as anemia. The effectiveness of both catechin and vitamin B12 depends on their stability and bioavailability, which can be lost during industrial processes due to degradation when exposed to external factors. A potential solution to this issue is the microencapsulation, which protects the compounds from external agents. The current study aims to microencapsulate EGCG and vitamin B12 in a polymer matrix o...

Association between adherence to the Mediterranean diet with anthropometric measurements and nutritional status in adolescents
CONCLUSION: adolescents' adherence to the Mediterranean diet was low and correlated with some anthropometric measures. Increasing adherence to the Mediterranean diet may contribute to preventing obesity and adequate and balanced nutrition in adolescents.PMID:36880734 | DOI:10.20960/nh.04545 (Source: Nutricion Hospitalaria)
