Brown and beige adipocytes express uncoupling protein-1 (UCP1), which is located in the inner mitochondrial membrane and facilitates the dissipation of excess energy as heat. The activation of thermogenic adipocytes is a potential therapeutic target for treating type 2 diabetes mellitus, obesity, and related co-morbidities. Therefore, identifying novel approaches to stimulate the function of these adipocytes is crucial for advancing therapeutic strategies.

Objectives: Increased nuclear factor (NF-kβ) and carbonyl stress due to decreased glyoxalase-1 activity (Glo-I) contribute significantly to insulin resistance and vascular complications. Therefore, we aimed to study the impact of the combination of thiamine and niacin on hepatic NF-kβ signaling, metabolic profile, and Glo-I activity in male rats with type-2 diabetes (T2DM).
Materials And Methods: Forty male rats were divided equally into five groups: control, diabetic, diabetic treated with thiamine (180 mg/l in drinking water), niacin (180 mg/l), and a combination of both.

Probiotics benefit the health and production performance of chickens, but their impact on egg and eggshell quality, particularly in the later stage, remains unclear. Here, 1-day-old Tianfu green shell-laying hens were fed either non-probiotics feed (n = 180) or feed supplemented with 100 mg / kg probiotics (n = 180). 16S rDNA sequencing indicated that dietary probiotics decreased the distribution of uterine p_Firmicutes, g_Fusobacterium, and s_Fusobacterium_unclassified, while increased p_Proteobacteria, g_Ralstonia, and s_Ralstonia_unclassified.

Wernicke's encephalopathy (WE) is a severe neurological condition caused by the deficiency of thiamine, which is a vitamin B1 molecule. Herein, we present the case of a 3-year-old girl with steroid-resistant nephrotic syndrome (SRNS) who did not achieve remission despite steroid pulse therapy (MPT) and rituximab. She had frequent vomiting and decreased oral intake on the 61st day.

NSUN6 preferentially catalyzes the methylation of cytosine nucleotides in mRNA substrates, which enhances transcription. Dysregulation of NSUN6 catalysis drives the oncogenesis of certain cancers. In this study, we determined the crystal structure of human NSUN6 in complex with its S-adenosyl-L-methionine analog and a bound NECT-2 3'-UTR RNA substrate at 2.
