Production of diverse brGDGTs by Acidobacterium Solibacter usitatus in response to temperature, pH, and O2 provides a culturing perspective on brGDGT proxies and biosynthesis

Geobiology, Volume 21, Issue 1, Page 102-118, January 2023., 2023
Abstract Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are bacterial membrane lipids that are frequently employed as paleoenvironmental proxies because of the strong empirical correlations between their relative abundances and environmental temperature and pH.

Socio‐economic status and the effect of guideline‐directed medical therapy in the STRONG‐HF study

ESC Heart Failure, EarlyView.
Abstract Aims Acute heart failure (AHF) impacts millions globally, with outcomes varying based on socio‐economic status (SES). Methods SES measured by annual household income, years of education and medical insurance coverage. Each patient's income and education level relative to the median or mean, respectively, in the country was calculated, and ...

The effects of FTO gene rs9939609 polymorphism on the association between breast cancer and dietary intake

Journal of Cellular and Molecular Medicine, Volume 26, Issue 23, Page 5794-5806, December 2022., 2022
Abstract Breast cancer (BC) is the leading cause of cancer‐related deaths in females worldwide and is related to genetic and environmental factors. Dietary components may strongly influence the risk of BC. A possible association was also reported between the fat mass and obesity‐associated (FTO) single‐nucleotide polymorphisms (SNPs) and BC. This study

The upregulation of thiamine (vitamin B1) biosynthesis in Arabidopsis thaliana seedlings under salt and osmotic stress conditions is mediated by abscisic acid at the early stages of this stress response [PDF]

, 2012
Background Recent reports suggest that vitamin B1 (thiamine) participates in the processes underlying plant adaptations to certain types of abiotic and biotic stress, mainly oxidative stress.

Mitochondria from cultured cells derived from normal and thiamine-responsive megaloblastic anemia individuals efficiently import thiamine diphosphate [PDF]

, 2002
BACKGROUND: Thiamine diphosphate (ThDP) is the active form of thiamine, and it serves as a cofactor for several enzymes, both cytosolic and mitochondrial. Isolated mitochondria have been shown to take up thiamine yet thiamine diphosphokinase is cytosolic

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.
