Pyruvic acid lay on the center position of Eremothecium ashbyii metabolic fluxes, during fermentation, a high performance liquid chromatography (HPLC) method is presented for the simultaneous determination of pyruvic acid in the Eremothecium ashbyii cell culture of both with ultrasound stimulation and the control. Dry weight and riboflavin are also mentored. The results of this study show that the ultrasound stimulation can give rise to pyruvic acid change, at the same time; change of pyruvic acid concentration is correlative to that of dry weight of mycelium and content of riboflavin.

VKM Ac-1390 (family Microbacteriaceae, class Actinomycetes) contains three rhamnose-containing glycopolymers in the cell wall, the structures of which were established by chemical and NMR spectroscopy methods. The first polymer, a rhamnomannan, consists of repeating tetrasaccharide units with xylopyranose side residues, →2)-α-[β-D-Xyl-(1→3)]-D-Rha-(1→3)-α-D-Man-(1→2)-α-D-Rha-(1→3)-α-D-Man-(1→. The second polymer found in minor amounts, is a rhamnan, →2)-α-D-Rha-(1→3)-α-D-Rha-(1→.

The hypoxic environment of solid tumors significantly diminishes the therapeutic efficacy of oxygen-dependent photodynamic therapy. Developing efficient photosensitizers that operate photoredox catalysis presents a promising strategy to overcome this challenge. Herein, we report the rational design of two rhenium(I) tricarbonyl complexes ( and ) with electron donor-acceptor-donor configuration.

Low phosphorus (P) use efficiency significantly impacts rice yields. An environmentally friendly approach to increase phosphorus absorption and utilization in rice involves the exploration of phosphorus-solubilizing fungal resources. This study aimed to isolate and characterize fungal strains from the rice rhizosphere and assess their phosphate solubilization capabilities, plant-growth-promoting (PGP) traits, and mechanisms involved.

Background: Osteopenia (ON) and osteoporosis (OP) are highly prevalent among postmenopausal women and poses a challenge for early diagnosis. Therefore, identifying reliable biomarkers for early prediction using metabolomics is critically important.
Methods: Initially, non-targeted metabolomics was employed to identify differential metabolites in plasma samples from cohort 1, which included healthy controls (HC, n = 23), osteonecrosis (ON, n = 36), and osteoporosis (OP, n = 37).
Head and neck squamous cell carcinoma (HNSCC) develops and advances because of the accumulation of somatic mutations located in orthosteric and allosteric areas. However, the biological effects of allosteric driver mutations during tumorigenesis are mostly unknown. Here, we mapped somatic mutations generated from 10 tumor-normal matched HNSCC samples into allosteric sites to prioritize the mutated allosteric proteins via whole-exome sequencing and AlloDriver, identifying the specific mutation H351Q in β-glucuronidase (GUSB), a lysosomal enzyme, as a novel allosteric driver mutation, which considerably encouraged HNSCC progression both in vitro and in vivo.
