Proteomic and Metabolomic Profiling Reveal Mitochondrial Transplantation–Mediated Reprogramming in Gastric Cancer Cells

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Mitochondria provide multiple functions for cellular physiology. Transplantation of mitochondria isolated from gastric epithelial cells GES‐1 reducing the malignancy of gastric cancer cells AGS was previously reported. To elucidate the underlying mechanisms, TMT‐based proteomic analysis coupling ingenuity pathway software prediction revealed ...

Effects of Ferrostatin‐1 on Vocal Folds in Aging Rats

The Laryngoscope, EarlyView.
Age‐related vocal fold degeneration is associated with oxidative stress, and ferroptosis may contribute to structural changes in aging vocal folds. In this aged rat model, intracordal injection of the antioxidant ferrostatin‐1 attenuated ferroptosis‐related changes and was associated with modulation of collagen accumulation, hyaluronic acid ...

Long‐Term Nitrogen Addition Weakens the Linkage Between Phosphorus Cycling Gene Abundance and Phosphatase Activity Through Soil Acidification in a Larix gmelinii Plantation

Land Degradation &Development, EarlyView.
ABSTRACT Anthropogenic nitrogen (N) enrichment propels global forest ecosystems toward phosphorus (P) limitation, theoretically triggering the upregulation of microbial P‐acquisition capacity to maintain stoichiometric balance. However, the extent to which N addition regulates this adaptive capacity remains uncertain.

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

Land Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.

Spectrophotometric Determination of Hydrazine

Analytical Letters, 2007
Hydrazine is determined spectrophotometrically by forming the derivative 2,4-dinitrophenylhydrazine from 2,4-dinitrochlorobenzene. The formed dinitro derivative undergoes condensation reaction to form the hydrazone with p-dimethylaminobenzaldehyde (p-DAB).

Spectrophotometric Determination of Anthramycin

Journal of Pharmaceutical Sciences, 1971
A quantitative UV spectrophotometric method for the determination of a new antitumor antibiotic, anthramycin, is described. The method is shown to be applicable for the determination of anthramycin in fermentation beers of Streptomyces refuineus var. thermotolerans (NRRL 3143) and in various preparations containing this antibiotic.

Spectrophotometric determination of formaldehyde

Talanta, 1988
A new spectrophotometric method for the determination of micro amounts of formaldehyde in aqueous and methanol solutions is based on the oxidation of formaldehyde by hydrous silver oxide at pH 11-12.5 and oxidation of the metallic silver produced, with iron(III) in the presence of Ferrozine. The absorbance of the resulting iron(II)-Ferrozine complex at

Spectrophotometric determination of astemizole

Talanta, 1998
Four simple and sensitive spectrophotometric methods for the determination of astemizole (AZ) in pure samples and pharmaceutical formulations are described. They are based on the oxidation of astemizole with excess N-bormosuccinimide (NBS) and determination of the unconsumed NBS with, metol-sulphanilamide (method A, lambda(max): 520 nm) or celestine ...
