Soil microorganisms are critical for soil carbon (C) cycling. They primarily regulate the turnover of the soil organic C (SOC) by adjusting their community structure, and contributing residues with a considerable amount to the resistant SOC. Nevertheless,

Chlortetracycline Residues in Broiler Tissue and Organs
Abstract Chlortetracycline was fed continuously to chicks at levels of 50–200 g/ton from the age of 1 day to 12 weeks; t h e tissue, blood, and organs were examined for residues. Average muscle tissue concentrations ranged from 0.036 to 0.109 μ/g in the feeding range, blood levels ranged from 0.043 to 0.076 μ/g, liver residues ranged ...

ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...
