S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

open access: yesThe FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

open access: yesThe FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).

The Implications of Atlantic Salmon (Salmo salar L.) Fatty Acid Profiles for Their Thiamine Status

open access: yesEcology and Evolution
Thiamine deficiency is an ongoing issue across the Northern Hemisphere, causing reproductive failure in multiple salmonid populations. In the Baltic Sea, a large brackish water system in northern Europe, previous research has suggested that this ...

Recent advances of emergent extraction technologies to enhance bioactive compounds extraction of microalgae—An overview towards application in cosmetics

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Microalgae extracts show immense potential in cosmetics for their bioactivities; emerging extraction techniques enhance bioactive compound yield from microalgae. Abstract Microalgae have attracted significant interest in numerous sectors, particularly in the cosmetic industries, owing to their rich composition of bioactive compounds. This paper aims to

Associative learning and thiamine based flavor preference [PDF]

open access: yes
The current experiment explored the extent to which thiamine deficiency at the time of conditioning is important as well as the importance of thiamine deficiency at the time of testing. This experiment controlled for previous experiments' flaws.

Cytosolic delivery of bacterial metabolites by riboflavin transporters promotes MR1 antigen presentation and MAIT cell recognition

open access: yesImmunology &Cell Biology, EarlyView.
VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.

Alcohol consumption and risk of dementia: a systematic review and meta‐analysis

open access: yesInternal Medicine Journal, EarlyView.
Abstract To examine the relationship between alcohol intake and the risk of developing dementia, we conducted a comprehensive search of PubMed, Embase, Cochrane Library and Web of Science databases for relevant studies up to July 22, 2024. The quality of the original studies was appraised utilising the Newcastle‐Ottawa Scale (NOS).

De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus

open access: yesJournal of Integrative Plant Biology, EarlyView.
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.
