RATIONALE: Diabetic ketoacidosis is a serious and potentially life-threatening acute complication of diabetes mellitus (DM). Euglycemic diabetic ketoacidosis (eDKA) is however challenging to identify in the emergency department (ED) due to absence of marked hyperglycemia, often leading to delayed diagnosis and treatment. eDKA has been recently found to be associated with sodium-glucose cotransporter 2 (SGLT2) inhibitors, one of the newest classes of antidiabetics, though there are very limited reports implicating dapagliflozin as the offending agent in ED patients...

This study assessed the protective effect of melatonin against muscle atrophy provoked by chronic immobilization stress (CIS). CIS was induced in rats by limiting their trunk movement for 90 min daily for 6 weeks. Rats subjected to the CIS procedure demonstrated a substantial decrease in body weight, an increase in serum corticosterone, muscle atrophy, and an increase in atrogin-1 mRNA levels. An increase in the serum lactate-to-pyruvate ratio and the oxidative stress accompanied by a reduction of Na+ /K+ ATPase activity could be responsible for these changes...

Desulfitobacterium hafniense Y51 has been widely used in investigations of perchloroethylene (PCE) biodegradation, but limited information exists on its other physiological capabilities. We investigated how D. hafniense Y51 confronts the debilitating limitations of not having enough electron donor (lactate), or electron acceptor (fumarate) during cultivation in chemostats. The residual concentrations of the substrates supplied in excess were much lower than expected. Transcriptomics, proteomics, and fluxomics were integrated to investigate how this phenomenon was regulated...

Recent studies show that Epstein-Barr virus (EBV) positivity might be related to adverse prognosis in patients with diffuse large B-cell lymphoma (DLBCL), but the results are still inconclusive. We conducted this meta-analysis to define the clinical value of EBV infection in DLBCL. All potential articles in PubMed, Web of Science, Medline, and Embase were retrieved. Using the random-effects or fixed-effect model, pooled hazard ratios (HRs) or relative risk (RR) with 95% confidence intervals (CIs) were used to calculate the correlation between EBER and prognosis and clinical features in DLBCL...

Single cell transcriptome (SCT) analysis provides superior resolution to illustrate tumor cell heterogeneity for clinical implications. We characterized four SCTs of MCF-7 using 143 housekeeping genes (HKGs) as control, of which lactate dehydrogenase B (LDHB) expression is silenced. These SCT libraries mapped to 11,423, 11,486, 10,380, and 11,306 RefSeq genes (UCSC), respectively. High consistency in HKG expression levels across all four SCTs, along with transcriptional silencing of LDHB, was observed, suggesting a high sensitivity and reproducibility of the SCT analysis...

OBJECTIVES: Esophageal squamous cell carcinoma is a highly prevalent cancer withpoor survival rate and prognosis. Increasing evidence suggests an important role for metabolic regulation in treating esophageal squamous cell carcinoma, but the underlying mechanism remains unclear. The pyruvate kinase M2 isoform is a key enzyme in the energy production process, and the upregulation of pyruvate kinase M2 isoform also plays a crucial role in gene transcription and tumorigenesis. The mammalian target of rapamycin pathway regulates an array of cellular functions, including protein synthesis, metabolism, and cell proliferation...

Mitochondrial aminoacyl-tRNA synthetases (mt-aaRSs) are a family of enzymes that play critical roles in protein biosynthesis. Mutations in mt-aaRSs are associated with various diseases. As a member of the mt-aaRS family, PARS2 encoding prolyl-tRNA synthetase 2 was recently shown to be associated with Alpers syndrome and certain infantile-onset neurodegenerative disorders in four patients. Here, we present two patients in a pedigree with early developmental delay, epileptic spasms, delayed myelination combined with cerebellar white matter abnormalities, and progressive cortical atrophy...

Fatty and hydroxycarboxylic acids are one of the main intermediates of energy metabolism in ruminants and critical in the milk production of cattle. High production demands on a dairy farm can induce nutritional imbalances and metabolism disorders, which have been widely associated with the onset of sterile inflammatory processes and increased susceptibility to infections. The literature suggests that short-chain fatty acids (SCFA), long-chain fatty acids (LCFA) and hydroxycarboxylic acids are relevant modulators of the host innate inflammatory response...

Dietary supplementation of oats has been associated with reduced risk of cardiovascular disease, diabetes, and gastrointestinal disorders. The role of oat extract as prophylactic in treating acute liver injury is not thoroughly established. We, therefore, hypothesized that oat extract would exert protective effect against alcohol-induced acute liver injury in a mouse model. To test this hypothesis, male C57BL/6 mice were pretreated with phenolic-enriched ethyl acetate (EA) fraction of oats (prepared by fractionating aqueous ethanolic extract with solvents of increasing polarity) at dosages of 125 and 250 mg kg-1 d-1 for 12 consecutive days...
